Answer:
x^2= 36
Step-by-step explanation:
since x = 6
therefore, x^2 = 6×6=36
Using the Pythagorean Theorem, the height of the equilateral triangle is given by:
A. 
inches.
<h3>What is the Pythagorean Theorem?</h3>
The Pythagorean Theorem relates the length of the legs 
and 
of a right triangle with the length of the hypotenuse h, according to the following equation:
For this problem, we have that:
- The height is one side of the triangle.
- The other side is half the length, of 7 in.
- The hypotenuse is the length, of 14 in.
Hence the height is found as follows:
inches.

Answer:
r =5 in
Step-by-step explanation:
Area of a circle is given by
A = pi r^2
We know the area and pi
78.5 = 3.14 r^2
Divide by 3.14
78.5/3.14 = 3.14 /3.14 r^2
25 = r^2
Take the square root of each side
sqrt(25) = sqrt(r^2)
5=r
Answer:
third grid
Step-by-step explanation:
.3×3=.9, as that is just .3 + .3 + .3
The third grid has 9/10 boxes colored, which is the same as .9
Hope this helps! :)
The probabilities of each number are equal. Then statements A and C are correct.
<h3>What is probability?</h3>
Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
Given
Pedro has a spinner with 4 sections numbered 1 through 4.
Pedro spins the spinner 100 times and records the results.
He calculates the relative frequency of each outcome.
Outcome 1 2 3 4
Relative Frequency 0.24 0.25 0.26 0.25
A) A uniform probability model is a good model to represent probabilities related to the numbers generated in Pedro's experiment. This statement is correct.
B) The theoretical probability that any one number is chosen is likely 0.20. This is incorrect because every number has an equal probability.
C) It is likely that the spinner is fair. This statement is correct because the probabilities of each number are equal.
D) The relative frequencies in the table are very different. This statement is incorrect. Because numbers 2 and 4 have the same frequency and the number 1 and 3 have slightly different frequencies.
