To test H 0​: p=0.40 that a population proportion equals 0.40​, the test statistic is a​ z-score that measures the number of sta

ndard errors between the sample proportion and the H0 value of 0.40. If z=3.8​, do the data support the null​ hypothesis, or do they give strong evidence against​ it?
(A) The data give strong evidence against the null hypothesis because the sample proportion falls over three standard errors from the null hypothesis value.
(B) The data support the null hypothesis because the sample proportion falls over three standard errors from the null hypothesis value.
(C) The data give strong evidence against the null hypothesis because the sample proportion falls within four standard errors from the null hypothesis value.
(D) The data support the null hypothesis because the sample proportion falls within four standard errors from the null hypothesis value.

The International Business Club starts the school year with $250.50 in their account. They spend $35 each month on activities. T
svlad2 [7]

Answer:

250.50 - 35m = 300 - 45.25m

Step-by-step explanation:

Whenever an equation asks for when it will take x (or m in this case) amount of things or time you should know that there will be 2 different equations that have to equal each other

The equation will be 250.50 - 35m = 300 - 45.25m

The 35m is being subtracted from 250.50 because they are losing money each time they spend. This also applies to 45.25m

Also 35m and 45.25m are variables because it says they spend that much money each month. They don't specify how many months, so we have to put a variable after it.

We can represent the cost of the notebooks with by saying 0.75n, and the cost of the pens by saying 0.55p.

0.75n+0.55p will be the total cost before tax.  Now, we need to add on tax.  Tax will be 0.0625 times the total amount, so we can represent the cost by saying 

(0.75n+0.55p) + 0.0625(0.75n+0.55p), so the answer is B.

Yakvenalex [24]

Answer: 28

Step-by-step explanation:

Given

Kenny made 7 serves over the net for every 2 serves that did not go over the net i.e. success rate of Kenny is

\Rightarrow \text{success rate}=\dfrac{7}{2+7}\times 100=\dfrac{700}{9}\%

for 36 serves, applying the same success rate, it is

\Rightarrow \text{success rate}=\dfrac{700}{9}\times\dfrac{1}{100}\times 36=28

Serves that did not make over the net is 36-28=8

Thus, Kenny will make 28 serves that make over the net
