The answer is A, because if he took the % of how many people attended the last game, that wouldn't be a sample. If he took a sample of the friends of the players, they don't necessarily have to be a part of the town. If he took a sample of the people who are on sports teams, that would just be dumb. He wanted to know how many people from the TOWN would attend. SO if he took a random sample of the people from the TOWN, he would have the most accurate answer.

Solve for x •26.45 •10.93 •14.26 •22.19 •20.26

ollegr [7]

Answer:

x = 26.45

Step-by-step explanation:

Cos theta = adjacent side / hypotenuse

cos 50 = 17 /x

Switch the x and the cos 50

x = 17 / cos 50

x =26.44730506

Rounding to 2 decimal places

x = 26.45

△HFM∼△PST

loris [4]

Answer:

The perimeter of △HFM is 50.75 units

Step-by-step explanation:

The correct picture of the question in the attached figure

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

we have

△HFM∼△PST ----> given problem

step 1

Find the scale factor

Let

z ----> the scale factor

$z=\frac{HF}{PS}$

substitute the given values

$z=\frac{14}{8}=1.75$

step 2

Find the perimeter of triangle PST

Remember that the perimeter of a triangle is the sum of its three length sides

$P=8+9+12=29\ units$

step 3

Find the perimeter of triangle HFM

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

The perimeter of triangle HFM is equal to the perimeter of triangle PST multiplied by the scale factor

$29(1.75)=50.75\ units$

What is the slope of the line that contains the points (1,-1) and (-2,8)? (Also can you show me how you got it please?)

ArbitrLikvidat [17]

The answer is -3

You use the formula y1-y2
———
x1-x2
-1 and 8 are your y’s
1 and -2 are your x’s

Your equation should look like this
-1-8 -9
—— = —— = -3
1-(-2) 3

I plugged the y’s and x’s into the formula.
I hope this helps!!

Jasmine rides her bike 9 miles in 50 minutes. what is jasmines speed per hour

Firdavs [7]

Given:

Given that Jasmine rides her bike 9 miles in 50 minutes.

We need to determine the speed per hour.

Time per hour:

The time taken is 50 minutes. We need to convert minutes into hours.

Thus, we have;

$\frac{50}{60}=\frac{5}{6} \ hr$
