Answer:
It would be the second option
Step-by-step explanation:
z:28 is the ratio of the shorter triangle's side to the larger triangle's side, so is 27:45.
Answer:
h = 7
Step-by-step explanation:
18 = (h - 1) × 6 × 0.5
simplify:
18 = 3(h - 1)
distribute the 3:
18 = 3h - 3
add 3 to both sides:
3h = 21
divide by 3:
h = 7
Answer:
B
Step-by-step explanation:
Our values are:
N = 100,000 (We assume it)
Proportion is p = 0.6
Margin of error (E) = 0.05
confidence-level (cl) = 0.95
Z-value = 1.96
We need to approach through Proportion,

Substituting,




The answer would be 2/5 is equal to 10/25 and 1/5 would be 5/25
15 + .65x = 80
15 + .65x = 80
15 - 15 + .65x = 80 - 15
.65/.65x = 65/.65
x = 100
