P=110+20h
where p is the total pay and h is the hours worked
<h2>5%</h2>
Step-by-step explanation:
let % be X
30 = x% of 600
30 = x × 600 / 100
x = 30 × 100 /60
x = 5

Answer:
D
Step-by-step explanation:
F(x) is an even degree. Because it opens up, it's leading coefficient is positive.
g(x) is an odd degree. Its leading coefficient is plus. A Minus one would go through quads 4 and 2, not 3 and 1
The last statement is the only true one.
30 more mins.because 40 percent in 20 mins=80 percent in 40 mins
and the 20 percent left is the same thing as 40/2 so then you also have to do 20mins/2=10
Answer:
- There is no significant evidence that p1 is different than p2 at 0.01 significance level.
- 99% confidence interval for p1-p2 is -0.171 ±0.237 that is (−0.408, 0.066)
Step-by-step explanation:
Let p1 be the proportion of the common attribute in population1
And p2 be the proportion of the same common attribute in population2
: p1-p2=0
: p1-p2≠0
Test statistic can be found using the equation:
where
- p1 is the sample proportion of the common attribute in population1 (
)
- p2 is the sample proportion of the common attribute in population2 (
)
- p is the pool proportion of p1 and p2 (
)
- n1 is the sample size of the people from population1 (30)
- n2 is the sample size of the people from population2 (1900)
Then
≈ 2.03
p-value of the test statistic is 0.042>0.01, therefore we fail to reject the null hypothesis. There is no significant evidence that p1 is different than p2.
99% confidence interval estimate for p1-p2 can be calculated using the equation
p1-p2±
where
- z is the z-statistic for the 99% confidence (2.58)
Thus 99% confidence interval is
0.533-0.704±
≈ -0.171 ±0.237 that is (−0.408, 0.066)
