The best thing to do is to find out what 1/7 is.
9/7= 1.28
1.28x3= 3.84
Therefore 3/7 of 9 is 3.84
Hope this helps :)

In math, "of" almost always means "times".

So your question is: 3/7 times (the number) = 9

Multiply each side of that equation by 7 : 3 times (the number) = 63

Divide each side by 3 : <em> The number = 21</em>

Answer:

0.2196

Step-by-step explanation:

Given that

Mean = 4.56 million visitors per day

Standard deviation = 820,000 visitors per day

According to the given situation the calculation of probability is shown below:-

Here we will find the value of P (3 ≤ X ≤ 4)

$P 93\leq X\leq 4)=P(X\leq 4) - P(X\leq 3)$

$\\=P(\frac{X-\mu}{\sigma}\leq \frac{4-4.56}{0.82})-P(\frac{X-\mu}{\sigma}\leq \frac{3-4.56}{0.82})$

$\\=P(Z\leq -0.683)-P(Z\leq -1.9024$

= 0.2483 - 0.0287

= 0.2196

Therefore the probability that the web site has between 3 million and 4 million visitors in a single day is 0.2196

(7t-2)-(-3t+1)=-3(1-3t)

Aleksandr-060686 [28]

First you need to multiple minus in second bracket, also in other side you need to multiple - 3 in bracket

$7t - 2 + 3t - 1 = - 3 + 9t \\ \\ 10t - 3 = - 3 + 9t \\ 10t - 9t = - 3 + 3 \\ t = 0$
Final answer is 0
