Answer:
c = -25017.87
Step-by-step explanation:
The slope of his trendline is 8,749 K
The two points that are used to find the slope of his trendline was (0.00286,4.27).
We need to find the y-intercept of his trendline. Slope of equation is given by :
y = mx +c
We need to find c.
Put y = 4.27, m = 8,749000 and x = 0.00286
c = y-mx
c = 4.27- 8,749000 (0.00286)
c = -25017.87
So, the y -intercept of his trendline is 25017.87
Could anyone help with “b” on the bottom. I’m not sure what it’s asking. Thank you!!
Answer:
yes
Step-by-step explanation:
the question is asking if the mean helped you find the number that pops up the most, so in this case 3.
by using the mean we will do
0+0+3+3+5+7+2+2+3+3+3+5 divided by 12
giving us a result of 3, in this case YES it does help at better explaining the typical value
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.

A local BBQ restaurants offers 2 side dishes with a lunch plate. There are 7 side dishes. How many choices of side dishes does a customer have
Step-by-step explanation:
This is a question that bothers combination. Combination has to do with selection.
When selecting r objects out of a pool of n objects, the number of ways this can be done is:
nCr = n!/(n-r)!r!
If a local BBQ restaurants offers 2 side dishes with a lunch plate, and there are 7 side dishes, the number of choices that the customer have is expressed as:
7C2 = 7!/(7-2)!2!
7C2 = 7!/(5)!2!
7C2 = 7*6*5!/5! * 2
7C2 = 7*6/2
7C2 = 42/2
7C2 = 21 choices
Hence the customer has 21 choices of side dishes to make

Find three consecutive even integers if their sum, decreased by the third, equals -22.
As per linear equation, the required three consecutive even integers those have a sum of - 22 are - 8, -10, - 12.
What is a linear equation?"An equation that has the highest degree of 1 is known as a linear equation. This means that no variable in a linear equation has an exponent more than 1. The graph of a linear equation always forms a straight line."
Let, three consecutive even integers are x, x+2, and x+4.
Therefore, sum of these three consecutive even integers is
= [x + (x + 2) + (x + 4)]
Given, the sum of the three consecutive even integers decreased by the third is - 22.
Now, [x + (x + 2) + (x + 4)] - (x + 4) = - 22
⇒ x + (x + 2) = - 22
⇒ 2x + 2 = - 22
⇒ 2x = -24
⇒ x = - 12
Now, x + 2 = - 12 + 2 = - 10
Similarly, x + 4 = - 12 + 4 = - 8
Therefore, required three consecutive even integers with a sum of - 22 are - 8, - 10, - 12.

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

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.
