Answer:
3.36 cm
Step-by-step explanation:
from the passage before ; the figure of question is similar to the first figure in passage because those triangles have an each equal angle.
Therefore the ratio of side is equal ; 1/0.84=4/x
Solve equation will be x(1)=4(0.84) ; x=3.36 cm
The answer is B. 13.9. Since M is the midpoint, it splits the line into 2 equal parts.
27.8 / 2 = 13.9

According to the hypothesis test, the option that gives the most appropriate method for creating such an estimate is:
A one-sample z-interval for a population proportion.
<h3>What is the hypothesis test?</h3>
He will test if there is enough support to build a new middle school, that is, if the population proportion that supports the building of a new middle school is greater than a threshold.
Only one sample is taken from the district residents, hence the correct option is:
A one-sample z-interval for a population proportion.

Hello there,
1/18 + 1/x = 1/2
<span>1/x = 9/18 - 1/18 </span>
<span>1/x = 8/18 = 4/9 </span>
<span>x = 9/4 or 2.25
