the amount of jen's monthly phone bill is normally distributed with a population mean of $86 and a population standard deviation of $9. between what two values are 68.26% of her phone bills? $ and $ . (your answers should be integers - no decimal places.)
If the amount of jen's monthly phone bill is normally distributed with a mean of $86 and standard deviation of $9, Between the values of $77 and $95 inclusive, 68.26% of Jen's phone bills are expected to fall.
To find the values between which 68.26% of Jen's phone bills lie, we need to use the properties of the normal distribution and the empirical rule.
The empirical rule states that for a normal distribution, approximately 68% of the data lie within one standard deviation of the mean. Therefore, we can find the values between which 68.26% of Jen's phone bills lie by calculating the range of values that are one standard deviation away from the mean.
Using the given population mean of $86 and population standard deviation of $9, we can calculate one standard deviation as follows:
One standard deviation = population standard deviation = $9
To find the lower and upper bounds for 68.26% of Jen's phone bills, we can subtract and add one standard deviation from the mean, respectively:
Lower bound = population mean - one standard deviation = $86 - $9 = $77
Upper bound = population mean + one standard deviation = $86 + $9 = $95

suppose the time to process a loan application follows a uniform distribution over the range 5 to 17 days. what is the probability that a randomly selected loan application takes longer than 11 days to process?
The probability that a randomly selected loan application takes longer than 11 days to process is 0.1587.
The time taken to process a loan application is uniformly distributed between 5 and 17 days.
We need to determine the probability that a random loan application takes longer than 11 days to process.
To compute the probability, we'll first determine the distribution's parameters;
we have: a = 5 (minimum value)b = 17 (maximum value)
Mean: μ = (a+b) / 2 = (5+17) / 2 = 11
Variance: σ2 = (b-a)2/12
= (17-5)2/12
= 12.3333Standard deviation:
σ = 3.516
For the problem, we want to find the probability of a loan application taking more than 11 days to be processed.
In other words, we want to find the probability of the application taking more than one standard deviation from the mean, that is, P(X > μ + σ).
Since the distribution is symmetric, we can also find the probability by calculating P(X < μ - σ) and subtracting the result from 1, since the total probability must be 1.
Using the above formula, we have:
P(X > μ + σ) = P(X > 11 + 3.516)
= P(X > 14.516)
To standardize the value of 14.516, we'll convert it to a z-score, which is z = (X - μ) / σ.
Therefore, we have z = (14.516 - 11) / 3.516 = 1
Since we are dealing with a standard normal distribution, we can use the standard normal distribution table to find the probability associated with z = 1.
From the table, we find that the probability of z being less than 1 is 0.8413;
thus, the probability of z being greater than 1 is 1 - 0.8413 = 0.1587.

To find out how much time June should work out each day to spend an even amount of time working out, we can first find the total amount of time she spent working out:
6/8 + 4/8 + 2/8 + 4/8 = 16/8 = 2 hours
Since there are four days she worked out, to find out how much time she should work out each day, we can divide the total time by four:
2 hours ÷ 4 = 0.5 hours
Therefore, June should work out for 0.5 hours, or 30 minutes, each day to spend an even amount of time working out.
Mai drove 355 miles using 17 gallons of gas. At this rate, how many gallons of gas would she need to drive 284 miles?
Answer: We can use a proportion to solve the problem:
17 gallons / 355 miles = x gallons / 284 miles
Cross-multiplying, we get:
17 * 284 = 355 * x
4844 = 355x
x = 13.66 (rounded to two decimal places)
Therefore, Mai would need approximately 13.66 gallons of gas to drive 284 miles at the same rate.

Bob can afford to deposit $400 a month into a retirement account that compounds interest monthly with an APR of 1.8%. His plan is to have $200,000 saved so that he can then retire. Approximately how long will it take him to reach this goal?
it will take Bob approximately 47.3 years to save $200,000 for his retirement.
How to find?
To determine the time it will take Bob to reach his retirement goal of $200,000, we can use the formula for compound interest:
A = P(1 + r/n)²(nt)
where:
A = the final amount
P = the initial principal (deposit)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the time (in years)
In this case, we have:
P = $400 (monthly deposit)
r = 1.8% (annual interest rate, compounded monthly)
n = 12 (compounded monthly)
A = $200,000
We can solve for t by substituting the given values and solving for t:
200,000 = 400(1 + 0.018/12)²(12t)
500 = (1 + 0.0015)²(12t)
log(500) = 12t log(1.0015)
t = log(500) / (12 log(1.0015))
t ≈ 47.3
Therefore, it will take Bob approximately 47.3 years to save $200,000 for his retirement.

Triangle ABC is similar to triangle DEF. The tangent of angle A is equal to 5/12. What is the sine of angle F? Enter the answer in the box. If necessary, enter the answer as a fraction in the simplest form.
Triangle ABC is similar to triangle DEF. The tangent of angle A is equal to 5/12 and the sine of angle F is 1/13.
How is the sine of an angle determined?The sine of the angle is the proportion of a right-angled triangle's hypotenuse to its perpendicular.
Triangle ABC and triangle DEF are similar in that their respective sides are proportional and their corresponding angles are equal. As a result, we have:
BC/EF = AC/DF = AB/DE
To determine the ratio AB/BC, we can utilise the tangent of angle A:
Tan(A) = 5/12 = AB/BC
By multiplying both sides by 12, we may make this simpler:
AB/BC = 12 tan(A).
We can now determine the ratio AB/EF using the ratio BC/EF:
AB/DE = BC/EF
This can be rearranged to yield AB/EF:
BC/EF * DE/AB = AB/EF
Due to the similarity of the triangles, we know that BC/EF = 12/13 and can therefore insert this into the equation:
(12/13) * (AB/DE) = AB/EF
Using the formula AB/DE = 5/12 (from above), we can reduce this:
AB/EF = (12/13) * (5/12) = 5/13
Finally, we may calculate the sine of angle F using the sine ratio:
sinning(F) = EF/DF
Using the ratio AB/EF that we recently discovered, we may rephrase this as follows:
sin(F) = (1/AB) * (AB/EF) = (1/AB) * (5/13)
Simplifying and substituting AB = 5k results in:
sin(F) is equal to (1/5k) x (5/13) x 1/(k*13).
We can select k = 1 because we want the response in its simplest form:
sin(F) = 1/13
As a result, 1/13 is the sine of angle F.

selects a car key or door key?
The probability that Mark selects a car key or door key from the key ring is 0.3 or 30%.
What is probability?
Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Probability theory provides a framework for understanding random events and the laws of chance, and it is an important tool for modeling and simulating complex systems.
Calculating the probability that he selects a car key or door key :
In this context, we are asked to find the probability of Mark selecting a car key or door key from the key ring. To calculate this probability, we need to first determine the total number of keys on the key ring and then count the number of car keys and door keys.
Total number of keys = 10
Number of car keys = 2
Number of door keys = 1
The probability of selecting a car key or door key can be found by adding the probability of selecting a car key to the probability of selecting a door key. Since there is only one door key and two car keys, the probability of selecting a car key is higher, and we can simplify the calculation by finding the probability of selecting a car key and then adding the probability of selecting a door key that hasn't already been selected.
Probability of selecting a car key = 2/10 = 0.2
Probability of selecting a door key = 1/9 (since one key has already been selected) = 0.1111...
Therefore, the probability of Mark selecting a car key or door key from the key ring is 0.2 + 0.1111... ≈ 0.3 or 30%.

B 18 x minus 9 = 72
C 18 x minus 15 = 72
D 3 (6 x minus 3) = 72
E x = 4.5
The following equations will have the same value of x as the one provided:
(B) 18x - 9 = 72; (D) 3(6x - 3) = 72; (E) x = 4.5
What are equations?A mathematical statement that uses the word "equal to" between two expressions with the same value is called an equation.
Like 3x + 5 = 15, for instance.
Equations come in a wide variety of forms, including linear, quadratic, cubic, and others.
So, the given equation is:
3/5(30x-15)=72
Now, we have:
3/5 * 30x - 3/5 * 15 = 72
18x - 9 = 72
Using common 3 as an example, we have the following on the left side of the equation:
3(6x-3) = 72
6x-3 = 72/3
6x-3 = 24
6x = 24+3
6x = 27
x = 27/6
x = 9/2
x = 4.5
Therefore, the following equations will have the same value of x as the one provided:
(B) 18x - 9 = 72; (D) 3(6x - 3) = 72; (E) x = 4.5

Subtract the following polynomials, then place the answer in the proper location on the grid. Write your answer in descending powers of x.
Subtract 2x2 - 6x - 4
from 4x2 - 4x + 3.
The answer to subtracting the two polynomials is 2x2 - 10x - 7. The process of subtracting polynomials is like that of subtracting any other type of numerical expression.
What are polynomials?Polynomials are mathematical expressions consisting of variables, coefficients, and exponents. They are used to represent a variety of functions, such as polynomial equations, rational equations, and trigonometric functions.
In this case, our like terms are 2x2 and 4x2, and -6x and -4x, and -4 and +3. We begin by subtracting the coefficients of the like terms. We subtract the coefficient of the term with the highest power first. In this case, that is 2x2 and 4x2, we subtract 2 from 4 to get 2. Next, we subtract the coefficients of the terms with the second highest power. This is -6x and -4x, so we subtract -6 from -4 to get -2. Thus, our answer now reads 2x2 -2x.
Finally, we subtract the coefficients of the terms with the lowest power. This is -4 and +3, so we subtract -4 from 3 to get -7. Thus, our answer now reads 2x2 -2x -7.
This answer can then be placed in the proper position on the grid.

Please help it’s urgent!!! Pls help!!! Will give brainliest!!Tina purchased a new refrigerator
on a payment plan. Four months after purchasing the refrigerator, the balance was $630. Six months after purchasing the refrigerator,
the balance was $520.
Write an equation that models the balance y after t months.
y = _t + _
Answer:
We can use the slope-intercept form of a linear equation to model the balance y after t months, where the slope represents the rate of change of the balance and the y-intercept represents the initial balance.
The initial balance (y-intercept) is the amount Tina borrowed to buy the refrigerator, which we don't know. But we can find the slope using the two data points provided:
Four months: balance = $630
Six months: balance = $520
The change in the balance over the two-month period is:
$520 - $630 = -$110
The slope of the line is the rate of change of the balance per month, which is:
slope = Δy/Δt = (-$110)/(6-4) = -$55/month
Using the point-slope form of a linear equation, we can plug in one of the data points to find the y-intercept:
y - 630 = -$55(t - 4)
y - 630 = -$55t + 220
y = -$55t + 850
Therefore, the equation that models the balance y after t months is:
y = -$55t + 850.

a ship travels 70 km on a bearing of 27 0 , and then travels on a bearing of 147 0for 180 km. find the distance of the end of the trip from the starting point.
The distance of the end of the trip from the starting point is 193.1321 km.
The ship goes 180 kilometers on bearing after 70 km of subsequent journey.
The starting point in this case is A, and the ending point is C.
We now discover distance AC:
As we can see, a right-angled triangle results.
The Pythagorean Theorem states that in a right triangle, the sum of the squares of the two sides that make up the right angle is equal to the square of the hypotenuse. This can be expressed mathematically as a^2 + b^2 = c^2, where a and b are the two sides that make up the right angle, and c is the hypotenuse.
Use Pythagoras's principle.
c = √a² + b²
The distance in the Hypotenuse in our case is now.
c = √(70)² + (180)²
c = √4900 + 32400
c = √37,300
c = 193.1321 km

Alyssa and Caleb were splitting nachos. Alyssa ate 1/2 of the nachos and Caleb ate 1/3 of the nachos.
What fraction of the nachos did they eat together?
Alyssa and Caleb ate 5/6 of the nachos together.
To calculate the fraction of nachos that Alyssa and Caleb ate together, add the fractions representing the portions that they each ate. However, because the fractions have different denominators, we must first find a common denominator.
2 and 3 share a common denominator of 6. With a denominator of 6, we can rewrite 1/2 and 1/3 as follows:
1/2 = 3/6
1/3 = 2/6
We can now add these fractions:
3/6 + 2/6 = 5/6
As a result, Alyssa and Caleb shared 5/6 of the nachos.
