Answer:
12 feet
Step-by-step explanation:
Draw a diagram (see picture below). The tree and its shadow is one triangle, the man and its shadow is another triangle. We assume both are right triangles because people and trees stand vertical.
Create a proportion to solve. Put the missing value in a numerator.
Tree height / Tree shadow = Man height / Man shadow
Solve using cross multiplication. Multiply x by 4. Multiply 6 by 8.
4x = 48 Divide both sides by 4 to isolate x.
x = 12 Height of tree
The tree is 12 feet tall.
Answer:
Step-by-step explanation:
Given
Required
Interpret p(4)
This implies that c = 4
Substitute 4 for c in
There are no option attached to this question.
<em>I'll assume c represents cost and p(c) represents the profit.</em>
<em>Base on this assumption, a suitable statement is:</em>
<em>When cost is 4, the profit is 5360.</em>
Answer:
A sample of 796 is needed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
In this question, we have that:
91% confidence level
So , z is the value of Z that has a pvalue of , so .
How large should a sample be if the margin of error is .03 for a 91% confidence interval
We need a sample of n, which is found when . So
Rounding up
A sample of 796 is needed.
What is 8 meters increased by 28%?
Well, first, you need to convert 28% to a decimal by moving the decimal two to the left by dividing by 100
28÷100=.28
or
28%⇒28⇒.28
Then you multiply
8 meters times .28
Then you add 2.24 to 8m (since its the original number)
Your answer is 10.24m
