The sum of three consecutive integers is 54. What are the integers? A. 17, 18, 19 B. 17, 19, 21 C. 18, 19, 20 D. 16, 17, 18
Answer:
Option A: 17,18,19 is the right answer.
Step-by-step explanation:
Let x be the first integer then the next two consecutive integers will be x+1, x+2
According to the given statement, the equation will be:
[tex]x + (x+1) + (x+2) = 54[/tex]
The equation is a linear equation in one variable, we have to solve the equation to get the values of integers
[tex]x+x+1+x+2 = 54\\3x+3 = 54\\3x = 54-3\\3x = 51\\\frac{3x}{3} = \frac{51}{3}\\x = 17[/tex]
Second integer = x+1 = 17+1 = 18
Third integer = x+2 = 17+2 = 19
The three integers are: 17,18 and 19
Hence,
Option A: 17,18,19 is the right answer.
Answer:
option a is the right answear trust

Consider population data with μ = 40 and σ = 4.(A) Compute the coefficient of variation(B) Compute an 88.9% Chebyshev interval around the population mean. ​What is the upper and lower limit?
Answer:
The answer is "[tex]10 \% ,\text{upper limit}=52,\ and \ \text{lower limit}=28[/tex]"
Step-by-step explanation:
Given value:
[tex]\mu =40\\\\\sigma=4[/tex]
In point a:
Calculating the value of the coefficient of variation:
[tex]\to C.V= \frac{6}{\mu} \times 100 \%\\\\ \to C.V= \frac{4}{\mu} \times 100 \% \\\\ \to C.V = 10 \%[/tex]
In point B:
when 88.9 \% of the value are lies then :
[tex]\to \mu \pm 36\\\\\to \mu -36 = 40-3\times 4 = 40 -12 =28\\\\\to \mu +36 = 40+3\times 4 = 40 +12 =52[/tex]
[tex]\text{upper limit}=52\\\\\text{lower limit}=28[/tex]

Answer:
[tex]x = - \frac{25}{3} [/tex]
Step-by-step explanation:
[tex] \frac{10}{3} = \frac{x}{( - \frac{5}{2}) } [/tex]
i) simplify the complex fraction[tex] \frac{10}{3} = - \frac{2x}{5} [/tex]
ii) simplify the equation using cross multiplication[tex]5(10) = - 2x(3)[/tex]
[tex]50 = - 6x[/tex]
iii) swap the sides of the equation[tex] - 6x = 50[/tex]
iv) divide both sides of the equation by -6[tex] \frac{ - 6x}{ - 6} = \frac{50}{ - 6} [/tex]
[tex]x = - \frac{50}{6} [/tex]
v) simplify the fraction[tex]x = - \frac{25}{3} [/tex]

Find the general solution of the given differential equation.y^(4)+18y"+81y=0
Answer:
The general solution of the given differential equation
[tex]y = ( c_{1} + c_{2} x ) cos3 x + ( c_{3} +c_{4} x) sin3 x[/tex]
Step-by-step explanation:
Step(I):-
Given differential equation
y⁴+18y"+81y=0
⇒ (D⁴+18D²+81)y =0
The auxiliary equation
[tex]m^4+18m^2+81 =0[/tex]
[tex](m^2)^{2} + 2 (9) m^{2} +(9)^2 = 0[/tex]
we will use formula ( a + b)² = a² + 2 a b + b²
⇒ ( m² + 9 ) ² = 0
⇒ ( m² + 9 ) ( m² + 9 ) = 0
[tex]m^{2} =-9\\m= - 3i and m=3i[/tex]
m² + 9 = 0
[tex]m² = -9\\m= -3i and m=3i[/tex]
The complex roots are 0± 3 i ,0 ± 3 i
Step(ii):-
The complementary function
[tex]y = e^{\alpha x } ( c_{1} + c_{2} x ) cos\beta x + ( c_{3} +c_{4} x) sin\beta x[/tex]
The general solution of the given differential equation
[tex]y = e^{0 x } ( c_{1} + c_{2} x ) cos3 x + ( c_{3} +c_{4} x) sin3 x[/tex]
The general solution of the given differential equation
[tex]y = ( c_{1} + c_{2} x ) cos3 x + ( c_{3} +c_{4} x) sin3 x[/tex]
Solve the following equation for x.
−13−4x−13x=−14+15x
Answer:
x = 0.84375
Step-by-step explanation:
-13 - 4x - 13x = 14 + 15x
-13 - 17x = 14 + 15x
-13 - 17x + 17x = 14 + 15x + 17x
-13 = 14 + 32x
-13 - 14 = 32x
-27 = 32x
-27 / -32 = 32x / 32
0.84375 = x

10+4x
40x
4+10x
10+x+x+x+x
Answer
The answer is 10 + 4x.
Step-by-step explanation:
Our base cost to enter is 10 dollars, and it is 4 dollars for each ride. Therefore, 10 dollars + 4(number of rides) = our total cost that Naomi spent at the fair.

Which expressions are equivalent to 6a(5+d) ?
SELECT EACH CORRECT ANSWER (theres more than 1)
30a+6ad
(6a⋅5)+(6a⋅d)
11a + d
30a+(6a⋅d)
30ad
Answer:
first, second and fourth
Step-by-step explanation:
If you use distribution,
6a(5+d) is the same as
6a(5) + 6a(d)
Multiplied = 30a + 6ad
So it's the 1st 2nd and fourth choice.
1st is stated above when multiplied out and combined.
2nd is after distribution.
4th choice is basically combination of 1 and 2 where one is combined (first term) and the second one just set up to be multiplied.
It cannot be third because you are multiplying the factors and not adding so you cannot have 11a.
It cannot be last choice because you have different types of terms that cannot be combined (one with a alone and one with ad)
Answer:
(6a*5) + (6a*d)
30a + 6ad
30a + (6a*d)
Step-by-step explanation:

Steve worked 7 hours Monday, 5 ¾ hours on Tuesday and 3.2 hours on Friday. If Steve earns $8.50 per hour, how much money did he earn for these three days?
Answer:
135.58 just did this
Step-by-step explanation:
First, I calculated the amount of money he got on Monday. I multiplied. 8.50 x 7 which equals 59.50. Then, I calculated the amount of money he got on Tuesday. I multiplied 8.50 (since that is the number of money he gets paid) to 3.2 (since that’s the amount of hours he works). I got 27.200. Then lastly, I calculated the amount of money he got on Friday. So first I changed 5 3/4 into a decimal. This is 5.75. After, I multiplied 8.50 x 5.75, and got 48.8750.lastly, I added and got 135.575. So if you round it, it will be 135.58
You are using an exponential smoothing model for forecasting. The running sum of the forecast error statistics (RSFE) is calculated each time a forecast is generated. You find the last RSFE to be 34. Originally, the forecasting model used was selected because of its relatively low MAD of 0.4. To determine when it is time to re-evaluate the usefulness of the exponential smoothing model, you compute tracking signals. Which of the following is the resulting tracking signal?A) 85B) 60C) 13.6D) 12.9E) 8
Answer:
A)85
Step-by-step explanation:
Calculation for the resulting tracking signal
Using this formula
Tracking signal= Last forecast error statistics (RSFE) /Low MAD (Mean Absolute Deviation)
Let plug in the formula
Tracking signal=34/0.4
Tracking signal=85
Therefore the resulting tracking signal will be 85

There is a bag with 10 balls inside it. 2
are footballs, 3 are soccer balls, 1 is a
softball, 2 are baseballs, and 2 are
basketballs. If you were to reach in and
grab one ball, what is the probability
that it is a softball or not a basketball?
Enter your answer in simplest form.
P(softball or not a basketball)=
The probability of grabbing a ball that is either a softball or not a basketball is 9/10, or 0.9 when expressed as a decimal.
What is probability?The likelihood or chance of an event occurring is measured by probability. Usually, it is stated as a number between 0 and 1, where 0 denotes an event's impossibility and 1 denotes its certainty.
According to question:There are 10 balls in total, and 2 of them are basketballs. So the number of balls that are not basketballs is 10 - 2 = 8.
Of these 8 balls, we know that 1 is a softball. So the number of balls that are either a softball or not a basketball is 1 + 8 = 9.
Therefore, the probability of grabbing a ball that is either a softball or not a basketball is:
P(softball or not a basketball) = 9/10
So the probability of grabbing a ball that is either a softball or not a basketball is 9/10, or 0.9 when expressed as a decimal.

Michelle purchases a pair of jeans for $35 and a dress for $47. The store charges 8% sales tax on all purchases. How much will Michelle need to pay for her purchase, including tax?
Answer:
Michelle needs to pay $88.56 to pay for her purchase, including tax.
Step-by-step explanation:
The purchasing cost of a pair of jeans = $35
The purchasing cost of dress = $47
The total purchase cost = $35 + $47
= $82
Given that the store charges 8% sales tax on all purchases.
Thus,
Tax amount = 8% × 82
= 8/100 × 82
= 0.08 × 82
= 6.56
The total cost including the tax = Tax amount + The total purchase cost
= 6.56 + 82
= $88.56
Therefore, Michelle needs to pay $88.56 to pay for her purchase, including tax.
