Answer:
12+36p
Step-by-step explanation:
First distribute the 2 to binomial then the 6.
6(2+6p)
12+36p
Answer:
Since the calculated value of z= -1.496 does not fall in the critical region z < -1.645 we conclude that the new program is effective. We fail to reject the null hypothesis .
Step-by-step explanation:
The sample proportion is p2= 7/27= 0.259
and q2= 0.74
The sample size = n= 27
The population proportion = p1= 0.4
q1= 0.6
We formulate the null and alternate hypotheses that the new program is effective
H0: p2> p1 vs Ha: p2 ≤ p1
The test statistic is
z= p2- p1/√ p1q1/n
z= 0.259-0.4/ √0.4*0.6/27
z= -0.141/0.09428
z= -1.496
The significance level ∝ is 0.05
The critical region for one tailed test is z ≤ ± 1.645
Since the calculated value of z= -1.496 does not fall in the critical region z < -1.645 we conclude that the new program is effective. We fail to reject the null hypothesis .
Answer:
Step-by-step explanation:
(3 x 9) + (5 + 8) + (33/3) = 51
27 + 13 + 11 = 51
<span> length (l), width (w), and height (h). Another way to think about the </span>volume<span> formula is as follows: V = l w h = (l w) h.</span>
