Because 44 is a bigger number than 4 it is 11 times bigger so the difference is larger than a proportional number
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 .
First you will get the sale price.
you need to convert the percentage to a decimal and to do that you move the decimal over twice:
30% = .30
then multiply the CD price by the decimal
$14.00 X .30 = $4.20
then you have the sales price but you need to find the tax price
to do that you move the decimal of the tax percentage over twice
7% = .07%
then multiply by the price after the sale included
.07 X $4.20 = $0.29
you have how much the tax would be
to get the total price you add the tax to the sales price
$0.29 + $4.20 = $4.42
the price you would be paying for this CD including tax is $4.42
Answer:
OB. FUX) =(x+6)*x+6) that is the answer
<em>You can get the graph of function g by taking the graph of function f and shifting it 7 units to the left, and by shifting it 7 units up.</em>
<h2>
Explanation:</h2>
We have the following functions:
But we can rewrite this functions as:
Or:
Recall that for vertical shifts:
From this, we know that:
- <em>We can get g(x) by </em><em>shifting the graph of f(x) 7 units upward</em>
Recall that for horizontal shifts:
From this, we know that:
- <em>We can get g(x) by </em><em>shifting the graph of f(x) 7 units to the left</em>
<em></em>
