gladu [14]

Divide 78 by 2

78 / 2 = 39 ( odd number)

so 78 would = the even number before and after 39

38 + 40 = 78

the larger number is 40

Hello!

So, the answer is 3.054545454545, and it goes on. I can't tell if that is C or D, but whichever one has a repeated sign on top, that's the answer.

Hope that helped!

In a psychology class, 32 students have a mean score of 93.2 on a test. Then 16 more students take the test and their mean score

liraira [26]

Answer: 83.3

Step-by-step explanation:

Formula :

$\text{Mean}=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}$ (1)

$\Rightarrow\ \text{Sum of all observations}=\text{Mean x (Number of observations)}$ (2)

Given : In a psychology class, 32 students have a mean score of 93.2 on a test.

By Using (2) , Sum of scores of 32 students = 93.2 x 32 =2982.4 (3)

Then 16 have a mean score of 63.4.

Again, By Using (2) , Sum of scores of 16 students = 63.4 x 16 =1014.4 (4)

Total students = 32+16 = 48

Add (3) and (4) , we get combined score of 48 students = 2982.4+ 1014.4

=3996.8

Now , by using (2) , the mean score of all of these students together

$=\dfrac{3996.8}{48}=83.2666666667\approx83.3$

Hence, the mean score of all of these students together is 83.3.
