982,510 books were downloaded in one year. Round this number to the nearest hundred thousand to estimate how many books were downloaded in one year. Use a numberline to show your work
Answer:
1,000,000.
Step-by-step explanation:
You are rounding to the nearest hundred thousand place value, which will be underlined and bolded:
982,510
Note that when you round, you look at the digit directly next to the place value you are solving for. Note:
If the value of the digit is 5 or greater, round up.
If the value of the digit is 4 or less, round down.
In this case, the value directly next to the place value is the ten thousands place, which has the value of 8. Because 8 is greater than 5, you will round up.
982510 rounded to the nearest hundred thousand is 1,000,000.

The mean useful life of car batteries is 55 months. They have a standard deviation of 2. Assume the useful life of batteries is normally distributed. a. Calculate the percent of batteries with a useful life of less than 51 months. (Round your answer to the nearest hundredth percent.) b. Calculate the percent of batteries that will last longer than 61 months. (Round your answer to the nearest hundredth percent.) a. Percent of batteries % b. Percent of batteries %
Answer: a. 0.13% b. 2.28%
Step-by-step explanation:
Let x denotes the useful life of batteries.
Given: months,
Since X is normally distributed.
The probability that batteries with a useful life of less than 38 months
The percent of batteries with a useful life of less than 38 months =0.13%
The probability that batteries will last longer than 68 months
The percent of batteries that will last longer than 68 months =2.28%

MN:Np=3:4 Let m:n=3:4
Use the formula
xN=(xM*n+xP*m)/(m+n)
yN=(yM*n+yP*m)/ (m+n)
xN= ((-12)*4+9*3)/ (4+3)=-3.

Mr. and Mrs. Samson are planning to build a fence around their garden. They are comparing the different measurements for their plans.
Plan A:
1.Posts are 4 ¼ feet in length
2. Post must be installed 7/8 feet below ground level.
Plan B:
1. Posts are 6 ¾ feet in length.
2. Posts must be installed 1 ½ feet below ground level.
1.What will be the height of the fence in plan A?
2. What will be the height of the fence in plan B?
3. Which fence will be taller and by how much?
4. Which plan would you recommend and why?
5. Mr. And Mrs. Samson decide to go with plan A and purchase the materials. Their total bill is $356.88. If they pay $220 in cash and charge the remainder, how much did they charge?
The relationship between the heights of the fence, the lengths, the distance below the ground level is an illustration of addition and subtraction.
The height of the fence is [tex]3\frac 38[/tex] in plan A and [tex]4\frac 34[/tex] in plan BThe fence in plan B is taller by [tex]2\frac{3}{4}[/tex] feet.The fence in plan B is recommended because: It is taller than the fence in plan A, and it goes below the ground level than plan AThey charge $136.88Plan A
[tex]Length = 4\frac 14[/tex]
[tex]Ground\ Level = \frac 78[/tex]
Plan B
[tex]Length = 6\frac 34[/tex]
[tex]Ground\ Level = 1\frac 12[/tex]
The height of the fence is calculated by subtracting the length below ground level from the length of the fence. So, we have:
[tex]Plan\ A = 4\frac 14 - \frac 78[/tex] [tex]Plan\ B = 6\frac 34 - 1\frac 12[/tex]
[tex]Plan\ A = \frac{17}{4} - \frac 78[/tex] [tex]Plan\ B = \frac{25}{4} - \frac 32[/tex]
Take LCM
[tex]Plan\ A = \frac{17\times 2 - 7}{8}[/tex] [tex]Plan\ B = \frac{25 - 3\times 2}{4}[/tex]
[tex]Plan\ A = \frac{34 - 7}{8}[/tex] [tex]Plan\ B = \frac{25-6}{4}[/tex]
[tex]Plan\ A = \frac{27}{8}[/tex] [tex]Plan\ B = \frac{19}{4}[/tex]
[tex]Plan\ A = 3\frac{3}{8}[/tex] [tex]Plan\ B = 4\frac{3}{4}[/tex]
Hence, the height of fence is [tex]3\frac 38[/tex] in plan A and [tex]4\frac 34[/tex] in plan B
The fence in plan B is taller because [tex]4\frac 34[/tex] is greater than [tex]3\frac 38[/tex]
The difference (d) in the heights is:
[tex]d = 4\frac 34 - 3\frac 38[/tex]
[tex]d = \frac{19}{4} - \frac{27}{8}[/tex]
Take LCM
[tex]d = \frac{19 \times 2 - 27}{4}[/tex]
[tex]d = \frac{38 - 27}{4}[/tex]
[tex]d = \frac{11}{4}[/tex]
[tex]d = 2\frac{3}{4}[/tex]
Fence in plan B is taller by [tex]2\frac{3}{4}[/tex] feet.
I will recommend the fence in plan B because:
It is taller than the fence in plan AIt goes below the ground level than plan AFor (5), we have:
[tex]Total = \$356.88[/tex]
[tex]Cash = \$220[/tex]
The remainder is the difference in the total amount and the amount they paid:
[tex]Charge = Total - Cash[/tex]
[tex]Charge = \$356.88 - \$220[/tex]
[tex]Charge = \$136.88[/tex]
Hence, they charge $136.88

Give the equation of a line that passes
through (9,2) and is parallel to:
y = 3x - 6
Answer:
y = 3x - 25
Step-by-step explanation:
If the line is parallel, it will have the same slope. So, the line will also have a slope of 3.
Plug in the slope and given point into y = mx + b, and solve for b:
y = mx + b
2 = 3(9) + b
2 = 27 + b
-25 = b
Plug in the slope and y intercept into y = mx + b:
y = mx + b
y = 3x - 25
So, the equation of the line is y = 3x - 25
find the measure of angle of ABF
Answer: m∠ABF = 120°
Concept:
Here, we need to know the idea of the corresponding angle theorem and linear pair postulate.
The corresponding angle theorem states that if a transversal cuts two parallel lines, their corresponding angles are congruent.
The linear pair postulate states that two angles that form a linear pair are supplementary.
Solve:
Given information
m∠ABF = m∠ABF = 2x + 3x
According to the corresponding angle theorem, ∠ABF is congruent to ∠BCI which is 2x + 4x.m∠BCH = 3x
Total angle = 180°
∠ABF and ∠BCH are linear pairs which means they form a supplementary angle.Given equation
m∠ABF + m∠BCH = Total Angle
Substitute values into the equation
2x + 4x + 3x = 180
Combine like terms
9x = 180
Divide 9 on both sides
9x / 9 = 180 / 9
x = 20
m∠ABF = 2x + 4x = 2 (20) + 4 (20) = 40 + 80 = 120°
Hope this helps!! :)

What is the probability that a normal random variable with mean 6 and standard deviation
3 will fall between 5.7 and 7.5
Answer:
z-score=7.5-6 1.5
___________=______=0.5
3 3
Step-by-step explanation:
Look up -0.1 on a z-table. The result is 0.4602. The means there is a 0.4602 probability the random variable will be below 5.7.
The find the probability the random variable will be between 7.5 and 5.7, simply subtract the two probabilities we found (above) from one another:
0.6915+-+0.4602+=+0.2313
So, there is a 0.2313 probability the random variable will fall between 7.5+and 5.7.
6) Split the following into a given ratio:
a) 72 into 1:3:5:
b) 150 into 2:3:
000029
Hub
(a)
Given:
72 to be split into 1:3:5
Solution:
First divide the amount with the sum of the ratio given
72 / 1 + 3 + 5 = 72 / 9 = 8
Now multiply the answer with each value:-
8 × 1 = 8
8 × 3 = 24
8 × 5 = 40
∴ The ratio will be 8:24:40
{To check your answer add to get the exact value: 8 + 24 + 40 = 72}
(b)
Given:
150 to be split into 2:3
Solution:
First divide the amount with the sum of the ratio given
150 / 2 + 3 = 150 / 5 = 30
Now multiply the answer with each value:-
30 × 2 = 60
30 × 3 = 90
∴ The ratio will be 60:90
{Now check your answer in the same way above: 60 + 90 = 150}
