-1.5 is the answer because it is 75
Answer:
17. is 20 18. is 9hours 19. is 60mph
you get this by doing 100 divided by 5 which equals 20 360 divided by 40=9 and 420 divided by 7 =60
Answer:
Step-by-step explanation:
start with 35 and add 1 repeatedly.
Option C: 6 is the value of 
Explanation:
The given expression is 
We need to determine the value of
To find the value of , let us substitute 
in the given expression.
Thus, substituting in the expression, we have,
Adding the terms, we get,
Since, we know the absolute rule that 
and the simplified expression is of the form 
, let us apply the absolute rule in the simplified expression.
Thus, we have,
Thus, the value of is 6.
Hence, Option C is the correct answer.
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 .
