Two similar prisms have proportional dimensions. Find the ratio between lengths of these prisms:
.
The ratio between volumes of similar prisms is
.
If volume of small prism is 50 cub. m, then
cub. m.
Answer: 137.2 cub. m.
Answer:
The first one- 24, The second one-B
Step-by-step explanation:
The first one-Top corner=110, 110+46=156, 180-156=24
The other one-I have no clue how to explain it

Answer with explanation:</h2>
Let p be the proportion of the correct answers.
As per given , we have

, since the alternative hypothesis is right tailed , so the test is a one -tailed test.
If the student gets 52 answers correct out of 80.
i.e. the proportion of correct answers : 
Test statistic : 

P-value :
[ by using p-value table for z (right-tailed)]
Since the p-value(0.0037) is less than the significance level (0.05), so we reject the null hypothesis.
Results : We have enough evidence to support the claim that a student knows more than half of the answers and is not just guessing.
First cross multiply to get:
80x = 65(x+3) (distribute)
80x=65x+195
15x=195 (subtract 65x from both sides)
x=13 (divide both sides by 15)
Hope this helps
