Find the value of x such that the data set has the given mean
100, 123, 105, 115, 110, x; mean 120

x=

Answers

Answer 1
The formula for mean is

all numbers added / how many numbers there are

Counting x, we have 6 terms.

(100 + 123 + 105 + 115 + 110 + x) / 6 = 120

Get rid of the denominator by multiplying 120 times 6.

100 + 123 + 105 + 115 + 110 + x = 720

Now, subtract everything on the left from 720 and isolate x.

100 + 123 + 105 + 115 + 110 = 553

720 - 553 = 167

x = 167

Answer 2
X is equal to 167 I think

12 touchdowns

Step-by-step explanation:

I hope I helped!!

12!
let t=number of touchdowns
your equation would be 10.75t=129
to do this, you would divide both sides of the equation by 10.75 to eliminate it from the t on the left side, leaving you with t=12. hope this helps!

Step-by-step explanation:

0.87          0.12

Hope this helps!

The two-way column relative frequency table is,

                                            Weekday                        Weekend  

Had an ice cream cone                0.29                              0.88                

Did not have an ice -                    0.87                               0.11            

cream cone  

          Total                                   1.00                                 1.00                        

What is two-way frequency table?

"It is a way to display frequencies for two categorical variables."

"One category is represented by rows and a second category is represented by columns."

Now, We need to find the column relative frequency table.

First we find the total of each column.

                                        Weekday                        Weekend  

Had an ice cream cone             23                                45            

Did not have an ice -                 155                                 6            

cream cone  

          Total                               178                                51                

Now, divide each element of column by its respective total.

                                              Weekday                        Weekend  

Had an ice cream cone               23/178                               45/51                

Did not have an ice -                    155/178                                6/51                

cream cone  

          Total                                  178/178                               51/51

Therefore, the two-way column relative frequency table would be,

                                          Weekday                        Weekend  

Had an ice cream cone                0.29                              0.88                

Did not have an ice -                    0.87                               0.11            

cream cone  

          Total                                1.00                                 1.00

Carmen runs 6 miles in 50 minutes. At the same rate, how many miles would she run in 35 minutes?

Answers

Answer:

4.2 miles

Step-by-step explanation:

6 miles/50 minutes = x miles/35 minutes

1. Since 5 is the GCF (greatest common factor) of x and 35, that is what the ratio must first be converted into, by dividing by 10: 6/50 = 0.6/5

2. To convert this to 35 minutes, it must be multiplied by 7, because 5 * 7 = 35. This leaves us with the answer:

0.6/5 = 4.2 miles/35 minutes

Match each equation to a step that will help solve the equation.

2) Multiply each side by -5.
3) Multiply each side by 1/5.
4) Multiply each side by -1/5.

B) x/5 = 8 — 1) Multiple by 5

C) 3 = -x/5 — 2) Multiple by -5

D) 7 = -5x — 4) Multiple by -1/5


Explanation:

A:
5x = 0.4

5x • 1/5 = 0.4 • 1/5

x = 2/25 or 0.08


B:
x/5 = 8

x/5 • 5 = 8 • 5

x = 40


C:
3 = -x/5

3 • -5 = -x/5 • -5

-15 = x

x = -15


D:
7 = -5x

7 • -1/5 = -5x • -1/5

-7/5 = x

x = -7/5 or -1.4
