P(A) = 0.7
P(B) = 0.8
P(A∩B) ⇒ When both event happens
P(A∩B) = 0.7 x 0.8 = 0.56
Answer: 0.56
Hey there,
6x + 5 (x-2)
6x + 5x - 10
11x - 10
3x - 5 - x + 9
3x - x - 5 + 9
2x + 4
3a + 5 - 8a + 1
3 (-1) + 5 - 8(-1) + 1
-3 + 5 + 8 + 1
11
Hope this helps :))

given that
c = 15h + 245
when h = 30.35 , cost c = (15 × 30.35) + 245
= 453.75 + 245 = 698.75
so cost if painter works = 698.75 unit of currency.
Answer:
P-value ≈ 0.3463
Step-by-step explanation:
Hypothesis test would be
:p=0.20
:p>0.20
We need to calculate the z-score of sample proportion and then the corresponding P-value.
z-score can be calculated as:
z=
where
- p(s) is the sample proportion of specimens yield before the theoretical point (
)
- p is the proportion assumed under null hypothesis. (0.20)
- N is the sample size (40)
Using the numbers
z=
=0.3953
and the P-value is then P(z)≈0.3463
2 is the max number because it's one less than the degree
