Chen recorded the number of texts he sent and the number of tweets he posted each day for a month. The equation y = 5x + 4,
where x is the number of texts and y is the number of tweets, models the relationship between these two quantities. Identify the
slope and explain its meaning within this context.
Answer/Step-by-step explanation:
The relationship between number of texts, x, and number of tweets, y, is represented in the slope-intercept form by the equation, y = 5x + 4.
The slope of this equation is 5.
In this context, the slope, 5, means 5 tweets are made for every 1 text sent each day.
This slope is positive meaning, as text sent increases, also, tweets increased.

What is the height of a solid cylinder with a mass of 26.05 g, a diameter of 3.56 cm, and a density of 2.72 g/cm^3?
Answer:
h = 0.962 cm
Step-by-step explanation:
Given that,
Mass of a solid cylinder, m = 26.05 g
The diameter of a cylinder, D = 3.56 cm
Radius, r = 1.78 cm
The density of a cylinder is 2.72 g/cm³
We need to find the height of the cylinder. Let it is h. We know that mass per unit volume is equal to density of an object. It can be given by :
[tex]d=\dfrac{m}{V}\\\\d=\dfrac{m}{\pi r^2 h}\\\\h=\dfrac{26.05}{\pi \times (1.78)^2\times 2.72}\\\\h=0.962\ cm[/tex]
So, the height of the cylinder is 0.962 cm.

The number of different simple random samples of size 5 that can be selected from a population of size 8 is
Answer:
Number of different simple random samples of size 5 that can be selected from a population of size 8 = 56 ways
Step-by-step explanation:
Step 1: Stating the combination formula
The number of selections of a number n, taking r at a time is given by the formula: [tex]\frac{n!}{(n - r!)r!}[/tex]
From the formula above, n is population size = 8
r is sample size = 5
Step 2: Substituting the values of n and r
Number of possible selections = 8!/(8 -5)*5! = 8!/3! * 5!
Number of possible selections = [tex]\frac{8*7*6*5*4*3*2*1}{3*2*1 * 5*4*3*2*1}[/tex]
Number of possible selections = 56
Therefore, number of different simple random samples of size 5 that can be selected from a population of size 8 = 56 ways

There are 8 more girls than boys in a school play. The ratio of boys to girls is 5:7. How many boys and how many girls are in the play?
Answer:
The total number of boys and girls in the play is 48
Step-by-step explanation:
Don't ask how I know this, I just do.
The number of boys in school play will be 20 and number of girls in school play will be 28.
What do you mean by ratio ?
Ratio is the quantitative relationship between two values indicating how frequently one value contains or is contained within the other.
It is given that number of girls is 8 more than boys in a school play.
Ratio of boys to girls = 5 : 7
Let's assume the total number of boys in school play is x.
This meant the total number of girls in school play is :
= x + 8
We can write them in proportion form as :
x : x + 8 = 5 : 7
or solving it we get :
[tex]\frac{x}{x+8}[/tex] = [tex]\frac{5}{7}[/tex]
or
7x = 5(x+8)
7x = 5x + 40
7x - 5x = 40
2x = 40
x = 20
or number of boys in school play is 20.
So , number of girls in school play will be :
= 20 + 8
= 28
Therefore , the number of boys in school play will be 20 and number of girls in school play will be 28.
