First, you want to set up the equation. 

0.25h = 9m
1.5h = x

(x represents the unknown amount of miles.)

Now that you have an equation set up, you cross multiply and get:
0.25x = 9 · 1.5
0.25x = 13.5
x = 54

So the horse runs 54 miles in 1.5h

Given the following points, write the equation of the line that goes through them. ( -12,56), (0,8), and (8,-24).
BaLLatris [955]

Answer:

y=-4x+8

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

take two points from the data

(0,8), and (8,-24).

substitute

m=\frac{-24-8}{8-0}

m=\frac{-32}{8}

m=-4

step 2

Find the equation of he line in slope intercept form

y=mx+b

we have

m=-4

b=8 ----> the y-intercept is given

substitute

y=-4x+8

A meteorologist who sampled 4 thunderstorms found that the average speed at which they traveled across a certain state was 16 mi
DENIUS [597]

Answer:

The  90 % confidence  interval  for the mean population is (11.176  ; 20.824 )

Rounding to at least two decimal places would give 11.18 , 20.83

Step-by-step explanation:

Mean = x`= 16 miles per hour

standard deviation =s= 4.1 miles per hour

n= 4

\frac{s}{\sqrt n}  =  4.1/√4= 4.1/2= 2.05

1-α= 0.9

degrees of freedom =n-1=  df= 3

∈ ( estimator  t with 90 % and df= 3 from t - table ) 2.353

Using Students' t - test

x`±∈ * \frac{s}{\sqrt n}

Putting values

16 ± 2.353 * 2.05

= 16 + 4.82365

20.824  ;        11.176

The  90 % confidence  interval  for the mean population is (11.176  ; 20.824 )

Rounding to at least two decimal places would give 11.18 , 20.83
