Answer:
P = 2l + 2w
solve for w
re-write
2l + 2w = P
subtract 2l from both sides
2w = P - 2l
divide both sides by 2
w = (P - 2l) / 2
Answer is B
w = (P - 2l) / 2
<span>c. 4.6
21 X .22= 4.6
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.</span>
Answer:
90
Step-by-step explanation:
The mode of the set is the number that occurs the most. In this case, 90 occurs more than any of the other terms. You can keep track using a tally chart:
80 |
82 |
90 ||
92 |
86 |
74 |
68 |
88 |
98 |
The answer would depend on where the numbers you gave us are on the pyramid. but here is the formula to find the surface area of a prism;
surface area= base x height + 2 x length x side + length x base
i will do the equation for you if you specify which numbers are the base, length, side, and height. or if you attach a photo.
