'is' means =

X =

3X + Y = P

3X = P - Y

X = (P - Y) ÷ 3

Answer:

m<4 = 117 degrees

Step-by-step explanation:

Knowing that angle 1 is 63 degrees, we can look at the other angle on the same side of the line, angle 4.

Angles on one side of a line add to 180 degrees.

180 - 63 = 117

Sati [7]

Answer:

Step-by-step explanation:

WE willl solve the question for the following equation $-8c-10+4c=-6c+8$

1. Add 8c on both sides

$8c-8c-10+4c = 8c-6c+8$

$-10+4c = 2c+8$

2. Add 10 on both sides

$10-10+4c = 10+2c+8$

$4c = 2c+18$

3. Substract 2c on both sides

$4c-2c = 2c+18-2c$

$2c =18$

4. Divide both sides by 2

$\frac{2c}{2}=\frac{18}{2}$

$c=2$

Then, the equation is solved.

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:

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