Given:
The equation of the trend line is:
[tex]y=-0.36x+12.6[/tex]
In this equation y represents the wind chill and x represents the wind speed.
To find:
The wind chill at 51 mi/h.
Solution:
We have,
[tex]y=-0.36x+12.6[/tex]
Putting [tex]x=51[/tex], we get
[tex]y=-0.36(51)+12.6[/tex]
[tex]y=-18.36+12.6[/tex]
[tex]y=-5.76[/tex]
Round the answer to the nearest degree.
[tex]y\approx -6^\circ[/tex]
Therefore, the wind chill at wind speed 51 mi/h is -6°.

Can someone please help me with math.
Answer:
C and A
Step-by-step explanation:
So first, off, to find the length of a line, we can use pythagreons theorm.(A^2+B^2=C^2) The cahnge in x squared and the change in y squared will give us C, which is the line length. You can count the tiles like this:
From the bottom point, lets count up the x coordinates till we hit the x coordinates of the top point. I got 3.
Next is the y coordinates.
When I count up until I reach the top point, I get 7. Lets plug these numbers in:
3^2+7^2=C^2
Use the square root on eahc number except for the unknown(C)
=
9+49=c^2
Add the two numbers together:
=
58=c^2
Take square root:
7.61=c^2
This can just be rounded to 7.6
This looks like C
So that is your first answer.
Next we have a table.
We need to look at the section of people that have both brown hair and eyes.
When I look at the table, I see 30 people whom how both these charcteristics.
When you looka the total people in the bottom right corner, you see that there are 120 people.
We do not even need to calculate percentage.
30 is 1/4 of 120.
What is 1/4 of 100%
25%
So the people with both brown eye/hair color is 25%
THis looks like answer A
I hope this helps! :)

At Lake View Middle School, there are 900 boys. The ratio of boys to girls is 5 to 4. How many girls are there in the school?
Answer:
320 girls
Step-by-step explanation:
We can make an algebric equation for this:
5x=900
x=180
We are asked to find the girls so we have to multiply the girls ratio by our x value we just found.
4x=4x180=320 girls

A book sold 42,000 copies in its first month of release. Suppose this represents 9.6 of the number of copies sold to date. How many copies have been sold to date?
Answer: 437,500 copies
Step-by-step explanation:
42,000 copies were sold in the first month and this is 9.6% of the total that have been sold till date:
To find the total that have been sold till date, assume the amount to be x.
Expression will be:
9.6%x = 42,000
x = 42,000 / 9.6%
x = 42,000 / 0.096
x = 437,500 copies
437,500 copies have been sold to date.
When Avani goes bowling, her scores are normally distributed with a mean of 145 and a standard deviation of 12. Using the empirical rule, determine the interval that would represent the middle 68% of the scores of all the games that Avani bowls.
Answer:(133,157)
Step-by-step explanation:
Using the empirical rule, the interval that would represent the middle 68% of the scores of all the games that Avani bowls is (133, 157).
What is Empirical Rule?Empirical rule is a rule for normally distributed data which defines that almost all the data observed ranges between three standard deviations from the mean.
Here, the scores of Avani is normally distributed.
Mean, μ = 145
Standard Deviation, σ = 12
By the Empirical rule, about 68% of the data falls within one standard deviation.
That is, in the interval μ ± σ.
Interval is (μ - σ, μ + σ) = (145-12, 145+12) = (133, 157)
Hence the interval is (133, 157).

Which function has an asymptote at x = 5 and an x-intercept of (6,0)?
OA
f(x) = log(x - 5)
B.
f(x) = log(x + 5)
OC. Ax) = log x-5
OD.
f(x) = log x + 5
Answer:
f(x) = log (x-5)
Step-by-step explanation:
__________
f(x) = log(x - 5) is the function has an asymptote at x = 5 and an x-intercept of (6,0)
What is a function?A relation is a function if it has only One y-value for each x-value.
we need to find the function which has an asymptote at x = 5 and an x-intercept of (6,0)
An asymptote is a line that the graph of a function approaches as either x or y go to positive or negative infinity.
There are three types of asymptotes: vertical, horizontal and oblique.
The asymptotes are lines, they are written as equations of lines. The vertical asymptotes are x = 5.
f(x) = log(x - 5) is the function has an asymptote at x = 5 and an x-intercept of (6,0)
Hence, f(x) = log(x - 5) is the function has an asymptote at x = 5 and an x-intercept of (6,0)

Step-by-step explanation:
The shape is fliped but when put to the point where the shapes look the same QP is congruent to DE. Shape DEFG is 2 times bigger than shape PQRS. So all the line measures on PQRS are 2 times smaller than those on DEFG. Meaning x or QP is equal to 18 since 36 divided by 2 is 18.
