Answer:
Product B performed better in the study because 76% got relief with this product, whereas only 70% got relief from product A
Step-by-step explanation:
Product A
Total number of people tested = 50
Total number o who experienced relief using product A
= 35
% of people who got relief using product A
= 35/50 x 100%
= 70%
Product B
Total number of people tested = 25
Total number of people who experienced releif using product B
= 19
% of peope who got relief using product B
= 19/25 x 100%
= 76%
From the above:
76% of people got relieved whilst using product B
70% who got relieved using product A.
Therefore, product B performed better in the study because 76% got relief with this product, whereas only 70% got relief from product A
Answer:
The length of the arc is 10 pi
Step-by-step explanation:
Mathematically, the length of an arc is calculated as;
theta/360 * 2 * pi * r
theta represents the central angle subtended by the arc which is a right angle according to the question (a right angle is 90 degrees)
r is the circle radius which is 20 inches
so we have the length of the arc as;
90/360 * 2 * pi * 20 = 40 pi/4 = 10 pi
Answer:
9.75 feet
Step-by-step explanation:
You use the pythagorean theorem to solve. A is the unknown, while b is 7 feet, and c is 12 feet
A^2 + 7^2 = 12^2
A^2 + 49 = 144
Subtract 49 from both sides to get
A^2 = 95
then take the square root of both sides to get
A (the height) = 9.74679434481
I usually round to 2 decimal points to get the answer 9.75 feet.
