Um i think that the answer is c.12.46
Answer:
First question the answer is the third one, 4*4*4*4*4
Second: Part A
I think one side is 25 yards, so answer is 25². that makes the area of the chicken pen to be 625 sqaure yards.
Part B a yard is exactly three feet, so the power becomes 75², and the area is 5625 square feet.
third question: not sure what the only use once is, but 2^4 and 4² could be the first one, they both equal 16. The second could be 3^4 and 9^2, which are both 81.
We are given a graph for the height of the ball with respect to horizontal distnace x of the ball from Julie.
From the graph, we can see the position of Julie is at (0,0). And starting height of the ball when thrown is 6 feet.
Then it moved to the maximum height of 14 feet. And hit to the ground when it has position on x-axis is 3.5 feet.
<em>Because we can see the parabola is crossing x-axis at 3.5 on the right.</em>
<em>That represents distance of the ball from Julie when it hit to the ground.</em>
<h3>Therefore, it has a horizontal distance of 3.5 feet from Julie.</h3>
Using a 1-sample z-interval for the population proportion with confidence level 0.997, the sample probability is 0.69 with margin of error of 0.16, so between 0.69+0.16=0.85 of the population and 0.69-0.16=0.53 of the population prefers coffee. 84% and 54% are the correct answers.
