I kind of forgot how to do it but here is what I know so far : first you separate the two parts into (5a^2 + 7a) + (6b^2-4b). This process is called grouping. Now you find the greatest common factor in both of them which later your equation will be a(5a + 7) +2b(3b - 2). That is all I can remember so hope that helped

A rental car company has noticed that the distribution of the number of miles customers put on rental cars per day is skewed to
kodGreya [7K]

Using the Central Limit Theorem, the correct option is:

(c) Average number of miles put on a rental car per day across 25 customers.

--------------------------

The Central Limit Theorem states that, for a normally distributed variable X, with mean \mu and standard deviation \sigma, the sample means of size m are approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

  • The interpretation related to this problem is that the larger the sample size, the smaller the standard deviation.
  • Thus, among the options, the largest sample is 25, thus, option c will have the smallest standard deviation.

radius of cylinder=3 cm

volume of cylinder=π r²h=π(3)²×18=162 π cm³

volume of sphere=4/3 π(3)³=36 π cm³

reqd. empty space=162 π-3×36π=54 πcm³

I need help solving 12 1/4 - 5 2/3<br> I’m having trouble
Lady_Fox [76]

Answer:

6 7/12

Step-by-step explanation:

We need to get a common denominator, which is 12

12 1/4 - 5 2/3

12 1/4*3/3 - 5 2/3*4/4

12 3/12 - 5 8/12

We will need to borrow from the 12 since 3/12 is less than 8/12.  Write the 1 we borrow as 12/12

11 + 12/12 + 3/12 - 5 8/12

11 15/12 - 5 8/12

6 7/12
