Answer:

Choice D is correct answer.

Step-by-step explanation:

We have given a list of values.

2,63,88,10,72,99,38,19

We have to find mean and value of n.

n is the total number of values.

Hence, n = 8

Formula to find mean is :

Mean = sum of values / number of values

Sum of values = 2+63+88+10+72+99+38+19 = 391

Number of values = 8

Mean = 391/8

Mean = 48.875

Mean of the following sample is 48.875

Given data set:

denpristay [2]

Answer:

see below

Step-by-step explanation:

6, 2, 7, 12, 6, 1, 7, 1, 9, 7, 8

First put the numbers in order from smallest to largest

1,1, 2,6,6, 7, 7, 7, 8, 9, 12

The mean is adding all the numbers and dividing by the number of numbers

( 1+1+ 2+6+6+ 7+ 7+ 7+ 8+ 9+ 12 )/11

66/1 =6

The mean is 6

The median is the middle

There are 11 terms

11/5 = 5.5 so 6 is the middle number

1,1, 2,6,6, 7, 7, 7, 8, 9, 12

7 is the median

Mode is the most often

7 appears three times so it is the mode

Answer:

Step-by-step explanation:

In No.1

First you find the total number of girls which is 56-20 =36 girls in total

So to get number of boys who watched tennis 20-13=7 boys watched tennis

To get number of girls who didnt watch you do 36-17=19 girls who watched

Then add o get the totals

No.2

First you get the total number of male 80-47=33 males

Next you find the number of females doing phyisics 33-19=14 females

Next you find the number of females doing chemistry by 47-(18 + 14)=15 females

To get the number of males diong chemistry 21-15=6 males

Number of males doing biology 33-(19+6)=8

Then find the remaining totals

No. 2 (b)

Because there is a high number of students doing physics and most of them are female

Step-by-step explanation:

Basketball :

uses 4 ounces of foam

20 minutes of labor

profit = $2.50

Football :

uses 3 ounces of foam

30 minutes of labor

profit = $2

Manufacturer has :

768 ounces of foam , 120 labor hours per week,

using the simplex method to determine the optimal production schedule so as to maximize profits

lets assume

x = number of basketball

y = number of footballs

maximize = 2.5 x + 2y from a linear programming problem

attached below is the detailed solution
