The experimental probability, sometimes known as the relative frequency, is the number of times the 'interesting' event occurs divided by the number of events in total that have occurred.

In your case, the 'interesting' event is rolling a 3. This happened 11 times.
The total number of events that have occurred is 7+9+11+6+9+8 = 50.

So the experimental probability of rolling a three is 11/50 = 0.22

A coordinate grid is placed over a college Station map. Tiger Stadium is located at (-3,2)

Olin [163]

Answer:

$4.61\ units$

Step-by-step explanation:

The complete question is

A coordinate grid is placed over a College Station map. Tiger Stadium is located at (-3, 2) and Kyle Field is located at (4, 8). If a shuttle bus stop is at the midpoint between Tiger Field and Kyle Field, which is the closest to the distance in coordinate units from Tiger Field to the shuttle bus stop?

Options

4.61 units

6.52 units

9.22 units

21.25 units

step 1

Find the midpoint between Tiger Field and Kyle Field ( shuttle bus stop)

we know that

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

$M=(\frac{x1+x2}{2},\frac{y1+y2}{2})$

we have the points

(-3, 2) and (4, 8)

substitute in the formula

$M=(\frac{-3+4}{2},\frac{2+8}{2})$

$M=(0.5,5)$

step 2

Find the distance from Tiger Field to the shuttle bus stop

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have the points

(-3,2) and (0.5,5)

substitute in the formula

$d=\sqrt{(5-2)^{2}+(0.5+3)^{2}}$

$d=\sqrt{(3)^{2}+(3.5)^{2}}$

$d=\sqrt{21.25}\ units$

$d=4.61\ units$

Donovan took a math test and got 20 correct questions and 5 incorrect answers. What was the percentage of correct answers?

solong [7]

ANSWER

80%

EXPLANATION

Donovan got 20 questions correct and 5 questions incorrect.

This means that the total number of questions he attempted in the test is the sum of correct and incorrect questions:

Total = 20 + 5

Total = 25

To find the percentage of correct answers, we have to divide the number of correct answers by the total number of questions attempted and multiply by 100 (per cent).

That is:

$\begin{gathered} \frac{20}{25}\cdot\text{ 100 = }\frac{4}{5}\cdot\text{ 100} \\ =\text{ 80\%} \end{gathered}$

That is the percentage of correct answers.
