12. It's similar to having an infinite number of solutions because there isn't a specific solution to answer the question.

13. For the equation 0.9x + 5.1x - 7 = 2(2.5x-3), there is only one solution and it is x=1

14. The error that your friend made was that she added extra 16x to the equation. the correct answer is that there is no solution.

16. the equation 6 (x+2)= 5 (x+7) has only one solution. it is x=3.

sorry i wasn't able to answer the other 3,

by the way you don't need to send money, because we are here to help

The lengths, in minutes, of the movies currently showing at a movie theater are shown in the data set. Create a histogram

alexdok [17]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the required lengths are not given.

I will use the following data set to answer the question.

$Dataset: 35, 51, 39, 42, 68, 62, 32, 59$

First, is to determine the range of the dataset

$Range = Highest - Least$

$Range = 68 - 32$

$Range = 36$

Next, we will make use of 4 classes. So, we divide range by 10 to get the number of class. 10 represents the interval

$Class= Range/10$

$Class = 36/10$

$Class = 3.6$

$Class \approx 4$

<em>So, we use 4 classes</em>

Plot the frequency distribution table as follows:

$\begin{array}{ccc}{Intervals} & {Observations} & {Frequency} & {31-40} & {32,35,39} & {3} & {41-50} & {42} & {1} & {51-60} & {51,59} & {2} & {61-70} & {62,68} & {2}\ \end{array}$

Paul is selling his paintings at the town Square. He has 35 paintings to sell in all and needs to sell at least 17 paintings in

Zarrin [17]

Answer:Paul should sell 3 paintings per hour to recover his cost.

Step-by-step explanation:

Total paintings = 32

Minimum amount to sale = 17

Paintings sold = 3

Paintings left = 17 - 3 = 14

Time left = 5 hours

Therefore, he needs to sell 14 paintings in 5 hours.

5 hours = 14 paintings

1 hour =

Rounding off to nearest whole number;

2.8 paintings = 3 paintings
