Part A: Create a scatter plot to represent the data shown above. Sketch the line of best fit. Label at least three specific points on the graph that the line passes through. Also include the correct labels on the x-axis and y-axis. Part B: Algebraically write the equation of the best fit line in slope-intercept form. Include all of your calculations in your final answer. Part C: Use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.
Answers
It is to be noted that the scatter plot that represent the above data is attached accordingly.
What is a scatter plot?A scatter plot is a graph in which the data of two variables are displayed along two axes, and any association is revealed by the pattern of the resultant dots.
Remember Scatter plot is a type of x-y graphX is the horizontal line and will be the AgeY is the vertical lien and will be Weight
What is the Algebraic equation of the best fit line in slope-intercept form? [Part B]
Slope-intercept form is y = mx + b
m is the gradient of the line, determined by calculating "change of y divided by change of x"
Age 2 and weight 32 would be the point (2, 32) on the graphAge 8 and weight 60 is the point (8, 60) in the graphTo compute for the gradient (m) we say:
(60 - 32)/(8-2)
= 28/6
m = 4.667
Next we calculate for b
The point on the graph where the line crosses the vertical line is known as the y-intercept, or b. (y-axis).
Put one of the graph's points, say (2, 32), and the amount of m you just computed into the slope-intercept form to calculate b.
That is:
32 = m(2) + b
Recall that m = 4.667
Hence 32 = 4.667 * 2 + b
32 = 6.667 + b
b = 32 - 6.667
b = 25.33
Using the equation for the line of best fit what is the approximate weight of the little girl at an age of 14 years old? [Part C]Given that we have the figures for m and b,
Recall that the function is: y = mx + b; and that
If x = 14 years, then
y = 4.667 * 14 + 25.33
y = 90.668
y ≈ 91 kg.

Milo recorded the number of hours he worked and the total amount he earned, including tips. Let h be the number of hours he worked, and let y be the total amount he earned, including tips. The equation of a line of best fit of his data is y = 12.5h +3.85. Based on the equation of the line of best fit, how much money should Milo expect to earn if he works a 5-hour shift?
Answers
Answer:
$66.35
Step-by-step explanation:
To find this answer with y=mx+b, we should first explain what it is. Y is our output or answer. M is our variable and x is the slope of our variable or how often it occurs. B, is our y intercept, our initial starting amount. Knowing this, we must figure out y. To do this we must multiply his hourly wage by the hours he works which is $12.50x5. This will get us $62.50. Now that we know how much he makes hourly, we add his initial wage of $3.85 to get us $66.35
This means he will make $66.35 if he works a full 5 hour shift.

66.35

Find the expected value of the winnings from a game that has the following payout probability distribution. Round to the nearest hundreath.
Answers
Step-by-step explanation:
Here, we want to calculate the expected value
What we have to do here is to multiply the probability by the payout value; after which we add all values
Thus, we have the payout value as;
1(0.12) + 4(0.2) +6(0.38) + 8(0.2) + 10(0.1)
= 0.12 + 0.8 + 2.28 + 1.6 + 1
The expected value of the winnings from a game will be [tex]2.96[/tex] .
What is Probability ?Probability is the ratio of the number of possible outcomes to the total number of outcomes.
we have,
Payout [tex](\$) = 0,\ \ \ 1,\ \ \ 2,\ \ \ 5,\ \ \ 10[/tex]
Probability [tex]=0.12,0.2,0.38,0.2,0.1[/tex]
So,
To find the expected value,
Now,
Multiply payout values with its probability and sum these values,
i.e.
Expected value [tex]= (0*0.12)+(1*0.2)+(2*0.38)+(5*0.2)+(10*0.1)[/tex]
[tex]=0+0.2+0.76+1+1[/tex]
Expected value [tex]=2.96[/tex]
Hence, we can say that the expected value of the winnings from a game will be [tex]2.96[/tex] .

What is the perimeter of the rectangle?
Answers
Answer:
10 feet
Step-by-step explanation:
Perimeter of rectangle = 2l+2b
Area of the rectangle = l x b
Area of the rectangle = 4 square feet
possible factors of 4 = 2x2/4x1
So sides of the rectangle are 4 & 1 as 2&2 would make it a square
So perimeter= 2x4+2x1
= 8+2

Jada has time on the weekends to earn some money. A local bookstore is looking for someone to help sort books and will pay $12.20 an hour. To get to and from the bookstore on a work day, however, Jada would have to spend $7.15 on bus fare.
Which equation will represent Jada’s take-home earnings in dollars, E, if she works at the bookstore for h hours in one day.
12.20h + 7.15 = E
12.20h - 7.15 = E
7.15h + 12.20 = E
7.15h - 12.20 = E
Answers
Answer:
B
Step-by-step explanation:
Answer:
E = 12.20(h) - 7.15
h = 6.82 hours
Given:
Pay hour = $12.20 per hour
Bus fare = $7.15
1.Equation:
Assume
She has work for "h" hours
Total earning = E
So,
E = 12.20(h) - 7.15
If,
Total earning = E = $90.45
So,
E = 12.20(h) - 7.15
90.45 = 12.20(h) - 7.15
h = 6.82 hours

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that for adults, a bowling alley charges $3.75 for shoe rental and $5 per game. For children, the cost is $2.50 for shoe rental and $4 per game.
For adults the expression will be:-
Ca = $3.75 + 5g
