Response: C. The cylinder possesses a larger volume.
Answer: He will require 10.07 cubic feet of sand for the wheelbarrows.
Step-by-step explanation:
Given that
the ratio of wheelbarrows filled with sand to those filled with concrete is expressed as

The volume of concrete in wheelbarrows is 248 cubic feet.
Then the volume of sand in wheelbarrows can be found as

Therefore, he will require 10.07 cubic feet of sand for the wheelbarrows.
Answer:
The value equals 1
Step-by-step explanation:
Consider the expression

Recall that


For two complementary angles A and B (where A+B=90°),
the identity is
cos(A) = sin(B)
Here, 26° and 64° are complementary angles, so

Substituting values,


From this, we find

By substitution,

The probability mass function of X equals 0.03. To clarify:
Assuming the requirement for winning is one side as heads and the opposing side as tails, the likelihood of both outcomes is 1/2 or 0.5. Thus, we can construct a graph to calculate all probabilities related to achieving heads. In this context, X indicates the dollar amounts won during the coin flips, while the probability of heads reflects the likelihood of each outcome and the potential winnings. The chances of winning decrease as the winning amount rises.
