Answer:

There are many different types of equations we can use to allow x to equal 19! Below are some examples :) See if you can come up with some on your own based off of these examples:

  • 5x = 95.....................................Divide both sides b 5

        x = 19.......................................There's one for you :)

  • 1 + x - 5 = 15............................Combine like terms

        x - 4 = 15..................................Add 4 to both sides

         x = 19

Write a formula to describe the sequence
Dominik [7]

Answer:

d

Step-by-step explanation:

A(n) = 1 - 0.1(n-1)

A(1) = 1- 0.1*(1-1) = 1 - 0.1*0 = 1

A(2) = 1- 0.1*(2-1) = 1 - 0.1*1 = 1- 0.1 = 0.9

A(3) = 1 - 0.1(3-1) = 1 - 0.1*2 = 1-0.2=0.8

Method:

A(1)=1

D = A(2)-A(1) = 0.9 - 1 = -0.1

A(n) = A(1)+(n-1)*d = 1 + (n-1)*(-0.1)

     = 1 - 0.1(n -1)

Aaaaa PLEASE HELPPPPP
kotegsom [21]

There are 20 cups and each one holds 10 fluid ounces. Assuming that she wants to fill them all up to the brim and use the complete 10 fluid ounces for each cup this means she would have a total of 200 fluid ounces: 20 * 10 = 200

1 gallon = 4 quarts

1 quart = 32 fluid ounces

This means that for every gallon she has 128 fluid ounces: 1 gallon (4 quarts/1gallon)(32 fluid ounces/1 quart) = 128

This means she needs at least 200 fluid ounces and she must buy another gallon to satisfy this; 128 * 2 = 256 fluid ounces.

She needs to buy 2 gallons but will have an extra 56 fluid ounces

Okay so plz answer this question step by step,, thank you <br>​

Given:

Total number of students = 20

The marks of the students are 40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37 and 40.

To find:

The frequency distribution table with class size 10.

Solution:

We have, the marks of 20 students.

40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37, 40

Here,

Minimum value = 12

Maximum value = 48

We nee class intervals of size 10. So, the required class intervals are 10-20, 20-30, 30-40, 40-50. In these intervals, lower limit is excluded but the upper limit included.

The required frequency distribution table is

Class intervals      Marks                                                  Frequency

10-20                    12, 15                                                            2

20-30                   22, 27, 20, 25                                             4

30-40                   36, 30, 31, 34, 36, 39, 36, 37                      8

40-50                   40, 41, 43, 48, 46, 40                                  6

Total                                                                                        20

Therefore, the frequency distribution table is

Class intervals:      10-20        20-30        30-40         40-50         Total

Frequency      :          2                4                8                6                20
