Tresset [83]
<span>Hilda wants to save 825 digital photograph in an online album.
Each folder of the said album can only save 6 photographs.
Now, let’s find out how many pages of the album will Hilda need to be able to store the 825 photograph,
=> According to the problem, she used division to get the answer.
Solution
=> how many 6s are there in 825:
=> 825 / 6
=> 137.5
The first digit in the quotient is in hundreds place.

-0.4(0.5z + 4) = 3.2<br> What is the answer for this
netineya [11]

Answer:

z = - 24

Step-by-step explanation:

Given

- 0.4(0.5z + 4) = 3.2 ( divide both sides by the multiplier - 0.4 )

0.5z + 4 = - 8 ( subtract 4 from both sides )

0.5z = - 12 ( divide both sides by 0.5 )

z = - 24

Explain how to perform a two-sample z-test for the difference between two population means using independent samples with
Effectus [21]

Answer:

Z= (X1`-X2`)- (u1-u2)/\sqrt{ \frac{ s_1^2}{n_1^2} +\frac{ s_2^2}{n_2}   (here s1=σ1 and s2= σ2)

Step-by-step explanation:

Let  X1` be the mean of the first random sample of size n1 from a normal population with a mean u1 and known standard deviation σ1.Let  X2` be the mean of the second random sample of size n2 from another normal population with a mean u2 and known standard deviation σ2. Then the sampling distribution of the difference X1`-X2` is normally distributed with a mean of u1-u2 and a standard deviation of

\sqrt{ \frac{ s_1^2}{n_1^2} +\frac{ s_2^2}{n_2} .  (here s1=σ1 and s2= σ2)  In other words the variable

Z= (X1`-X2`)- (u1-u2)/\sqrt{ \frac{ s_1^2}{n_1^2} +\frac{ s_2^2}{n_2}   (here s1=σ1 and s2= σ2)

is exactly standard normal no matter how small sample sizes are . Hence it is used as a test statistic for testing hypotheses about the difference between two population means.

The procedure is stated below.

1) Formulate the null and alternative hypotheses.

2) Decide on significance level ∝

3) Use the test statistic Z= (X1`-X2`)- (u1-u2)/\sqrt{ \frac{ s_1^2}{n_1^2} +\frac{ s_2^2}{n_2}   (here s1=σ1 and s2= σ2)

4) Find the rejection region

5)Compute the value of Z from the sample data

6) Rehect H0 if Z falls in the critical region, accept H0 , otherwise.

Nicole has a loyalty card good for a 18% discount at her local pharmacy. What
steposvetlana [31]

so let's say the sale price is "P", so Nicole would want to know how much will it be P discounted by 18% of P.

Well, the sale price will just be P or 100% of P, minus 18%, the discounted price will be 100% - 18% = 82%, so the discounted price will be 82% of P.

\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{82\% of P}}{\left( \cfrac{82}{100} \right)P}\implies \boxed{0.82}\cdot P\qquad \impliedby \textit{discounted price}
