Answer:
20 million
Step-by-step explanation:
5 million SUVs are 25% of the total number of vehicles.
0.25x = 5,000,000
x = 20,000,000
Answer: 20 million
The question is an illustration of proportions.
A total of 20 million vehicles were looked into
The proportions are given as:
[tex]SUV = 25\%[/tex]
[tex]Trucks= 10\%[/tex]
Let the total number of vehicles be v.
The number of SUVs is given as 5 million.
So, we have:
[tex]SUV = 25\% \times v[/tex]
Substitute 5 million for SUV
[tex]5\ million= 25\% \times v[/tex]
Express the percentage as decimal
[tex]5\ million= 0.25 \times v[/tex]
Divide both sides of the equation by 0.25
[tex]20\ million = v[/tex]
Rewrite the equation as
[tex]v =20\ million[/tex]
Hence, 20 million vehicles were looked into

he heights of one hundred trees in a certain forest are measured. It’s found that the mean height of the trees is 48 feet. Use this information to answer the following:
Would it be possible to have a standard deviation of 7.5 feet? If so, what would this tell us about the tree heights in the forest?
Would it be possible to have a standard deviation of 1? If so, what would this tell us about the tree heights in the forest?
Would it be possible to have a standard deviation of 0? If so, what would this tell us about the tree heights in the forest?
Would it be possible to have a standard deviation of -2.5? Why or why not?
Using the concept of standard deviation, it is found that:
It would be possible to have standard deviations of 7.5 feet and 1 feet, which would mean that the distribution of tree heights are normal.It would be possible to have a standard deviation of 0 feet, which would mean that all trees have the same height.It would not be possible to have a standard deviation of -2.5 feet, as it is always a positive value.The standard deviation of a data-set is given by the square root of the sum of the differences squared of each observation and the mean, divided by the one less than the number of values. It is always a positive value, thus, a standard deviation of -2.5 feet, for example, is not possible.If a data-set has a standard deviation of 0, it means that all values in the data-set are the same.In a normal distribution, 99.7% of the measures are within 3 standard deviations of the mean.
[tex]48 \pm 3(7)[/tex] and [tex]48 \pm 3(1)[/tex] are both reasonable distributions for the tree heights, thus, it is possible to have standard deviations of 7.5 and 1 feet.

janet obtained 32% for her statistics test, which was out of a total of 300 marks. how much should she score in the computer science test that is out of 200 marks in total if she is to get proportionally weighted average of 46%
Her score in computer to get a proportionally weighted average of 46% will be 134.
The total score for both subjects = 200 + 300 = 500
Since the proportionally weighted average is 46%, then her score will be:
= 46% × 500
= 0.46 × 500
= 230
Since she had 32% for her statistics test, which was out of a total of 300. Her score will be:
= 32% × 300
= 0.32 × 300
= 96
Therefore, her score in computer will be:
= 230 - 96
= 134

Step-by-step explanation:
Answer: (x^7)/(x^4) = x^3, x^(-3) = 1/(x^3), x^0 = 1, (x^4)/(x^3) = x
Step-by-step explanation:
Dividing two exponents with the same base can be simplified by subtracting the exponents. Thus (x^7)/(x^4) is the same as x^(7-4), or x^3.
A negative exponent is the same as the reciprocal of the positive exponent. x^-3 is the same as 1/(x^3).
Anything with an exponent of 0 is equal to 1.
Again, when dividing two exponents, if they have the same base, you can just subtract the exponents. (x^4)/(x^3) = x^(4-3) = x^1 = x.

Swimming Pool On a certain hot summer's day, 492 people used the public swimming pool. The daily prices are $1.50 for children and $2.50 for adults. The receipts for admission totaled $1060.00. How many children and how many adults swam at the public pool that day?
There were ______ children at the public pool.
Answer:
# of children = 170, # of Adults = 492 - 170 = 322
Step-by-step explanation:
Define C and A as
C = # of children
A = # of adults
Then,
A + C = 492
1.5C + 2.5A = 1060, so that
1.5C + 2.5(492 - C) = 1060
1.5C + 1230 - 2.5C = 1060
-C = 1060 - 1230
C = 170

Charlie drove 495 miles in 9 hours. How long would it take to drive 715 miles?
Answer:
13 hours
Step-by-step explanation:
if he drives 495 miles in 9 hours, he drives 55 miles each hour. 55x13=715
Answer:
13 hours
Step-by-step explanation:
Charlie drove 495 miles in
= 9 hours
∴ Rate
= miles/hours
= 495/9
= 55 miles per hour
∴ No. of hours to travel 715 miles
= miles/miles per hour
= 715/55 hours
= 13 hours
Thus, 13 hours would it take to drive 715 miles.

Perpendicular to y=-3x+11 and goes through the point (-9,-6)
please help it’s due next period
Answer:
y = 1/3x - 3
Step-by-step explanation:
If the line is perpendicular to y = -3x + 11, it means that the two gradients multiply to make -1.
So the gradient of the perpendicular line is 1/3 (-3 × 1/3 = -1)
y = 1/3x + c
Next, substitute x = -9, and y = -6 to find the y intercept, or c:
-6 = 1/3(-9) + c
-6 = -3 + c
c = -6 + 3
c = -3
The equation of the line is y = 1/3x - 3

Engineering An overpass intersects two
lanes of a highway. What must the value of x
be to ensure the two lanes are parallel?
Answer:
Look down :)
Step-by-step explanation:
The two equations must equal 180 degrees. So what you could do it 4x + (2x + 12) = 180
then solve. If this isnt enough information just comment :)
If no I hope this helped
For the two lanes to be parallel, the value of x must be 28 degrees,
The given information states that the same-side interior angles are 4x degrees and (2x + 12) degrees.
For parallel lines, the sum of these angles must equal to 180 degrees.
As per the concept of linear sum,
4x + (2x +12) = 180
Adding the like terms, we get:
(4x + 2x) + 12 = 180
Simplifying, we get:
6x + 12 = 180
Subtract 12 to both sides, and we get:
6x = 180 - 12
Simplifying, we get:
6x = 168
x = 28
Therefore, the value of x is 28 degrees.
