Answer:
Fail to reject the null hypothesis.
Step-by-step explanation:
The hypothesis test is conducted for Boston public school. They have used z-value table and the value of test statistics is 1.20. AT the significance level of 0.05, the null hypothesis is accepted. We cannot reject the null hypothesis. The p-value is greater than alpha so there is no evidence to support the claim of Boston Public School.
1
Simplify n\times \frac{6}{9}n×96 to \frac{2n}{3}32n
\frac{2n}{3}=\frac{3}{12}32n=123
2
Simplify \frac{3}{12}123 to \frac{1}{4}41
\frac{2n}{3}=\frac{1}{4}32n=41
3
Multiply both sides by 33
2n=\frac{1}{4}\times 32n=41×3
4
Simplify \frac{1}{4}\times 341×3 to \frac{3}{4}43
2n=\frac{3}{4}2n=43
5
Divide both sides by 22
n=\frac{\frac{3}{4}}{2}n=243
6
Simplify \frac{\frac{3}{4}}{2}243 to \frac{3}{4\times 2}4×23
n=\frac{3}{4\times 2}n=4×23
7
Simplify 4\times 24×2 to 88
n=\frac{3}{8}n=83
Answer: 
Step-by-step explanation:
Let be "l" the number of CDs Ms.Kitts sold last week, and "t" the number of CDs she sold this week.
You need to remember that:
1. The word "times" indicates a multiplication.
2. The word "more" indicates addition.
Then, the sentence "Last week she sold 6 more than 3 times the number of CDs that she sold this week" can be represented with equation:
According to the information given in the exercise, the sum of the number of CDs Ms. Kitts sold last week and this week is: 110 CDs.
Since a sum is the result an Addition, you can write the following equation:
Therefore, the System of equations that can be used to find the number of CDs she sold last week and the number of CDs she sold this week, is:
