Answer:
5=b
Step-by-step explanation:
Eliminate the parenthiesies --> n-2+7 = bn
Move the variables to one side (they cancel eachother out) --> -2+7 = bn
Solve --> 5=b
of
is ![6\frac{1}{7}](https://tex.z-dn.net/?f=6%5Cfrac%7B1%7D%7B7%7D)
Solution:
Given
of what number is
.
Let us first convert the mixed fraction into improper fraction.
![$2\frac{2}{3}=\frac{(2\times3)+2}{3}=\frac{8}{3}](https://tex.z-dn.net/?f=%242%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7B%282%5Ctimes3%29%2B2%7D%7B3%7D%3D%5Cfrac%7B8%7D%7B3%7D)
![$6\frac{1}{7}=\frac{(6\times7)+1}{3}=\frac{43}{3}](https://tex.z-dn.net/?f=%246%5Cfrac%7B1%7D%7B7%7D%3D%5Cfrac%7B%286%5Ctimes7%29%2B1%7D%7B3%7D%3D%5Cfrac%7B43%7D%7B3%7D)
Now, let us take the unknown number be x.
![$2\frac{2}{3}\times x=6\frac{1}{7}](https://tex.z-dn.net/?f=%242%5Cfrac%7B2%7D%7B3%7D%5Ctimes%20x%3D6%5Cfrac%7B1%7D%7B7%7D)
![$\frac{8}{3}\times x=\frac{43}{7}](https://tex.z-dn.net/?f=%24%5Cfrac%7B8%7D%7B3%7D%5Ctimes%20x%3D%5Cfrac%7B43%7D%7B7%7D)
Do the cross multiplication.
![$ x=\frac{43}{7}\times\frac{3}{8}](https://tex.z-dn.net/?f=%24%20x%3D%5Cfrac%7B43%7D%7B7%7D%5Ctimes%5Cfrac%7B3%7D%7B8%7D)
![$ x=\frac{43\times3}{7\times8}](https://tex.z-dn.net/?f=%24%20x%3D%5Cfrac%7B43%5Ctimes3%7D%7B7%5Ctimes8%7D)
![$ x=\frac{129}{56}](https://tex.z-dn.net/?f=%24%20x%3D%5Cfrac%7B129%7D%7B56%7D)
Now, again change the improper fraction into mixed fraction.
![$ x=2\frac{17}{56}](https://tex.z-dn.net/?f=%24%20x%3D2%5Cfrac%7B17%7D%7B56%7D)
Hence
of
is
.
Your answer is the 3rd option, 23
Absolute values result in just the positive version of the number on the inside.
This gives us:
6 + 3(4) + 5 - 0 x 6
PEMDAS tells us to multiply first so we do.
6 + 12 + 5 - 0.
Now add like regular.
18 + 5 = 23.
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.
