Step-by-step explanation:
The line y= -x + 3 best models which of the following scatter plots?
Answer:
a
Step-by-step explanation:
Since we have a negative slope, that means the correlation for the scatter plot also has to be negative.
Since the only scatter plot that has a negative correlation is graph A, a is our answer.
Chicken eggs can be categorized as large if they weigh at least 2 ounces. Clare weighs 48 large eggs and finds that they have a mean weight of 2.1 ounces and a mean absolute deviation of 0.08 ounces. Interpret 0.08 ounces in this situation.
Answer: The average difference of weights of all 48 eggs from mean eight is 0.08.
Step-by-step explanation:
The mean absolute deviation of a data interprets the mean distance between each data point and the mean.
When this distance goes larger it means data has greater variability
Given, 48 large eggs have a mean weight of 2.1 ounces and a mean absolute deviation of 0.08 ounces.
It means that the average difference of weights of all 48 eggs from mean eight is 0.08.

Answer:
45°
Step-by-step explanation:
gradient of the line:
Let A (-1,-3) and B (5,3)
tan a = (yB - yA) / (xB - xA) = (3 - -3) / (5 - -1) = 6/6 = 1
--> the angle made by the line and positive direction of x-axis is:

The area of a rectangular wall of a barn is 90 square feet. It’s length is 8 feet longer than twice it’s width. Find the length and width of the wall of the barn
Answer: The answer is that the length is square ft, and the width is .
Step-by-step explanation:
The length and width of the wall of the barn are 18, 9
What is the area of rectangle?The area of rectangle is product of length and width
Given area of rectangle is 90 ft²
given length = 8 ft + 2ₓ width
l = 8 +2 w
area = l × w
90 = (8 +2 w) × w
90= 8w +2w²
2w²+ 8w -90 =0 or w²+4w - 45 =0
On solving w= 9, -5
as width cannot be negative so w= 9
l= 8+2×9
l=26
Thus the length and width of the wall of the barn are 18, 9

Student’s Work
Student’s Answer
A. y= 9200x+1400; 10,600 lbs
B. y= 5000x+1400; 21,400 lbs
C. y= 1400x+ 5000; 10,600 lbs
D. y= 5000 +41400; 21,400 lbs
Answer:
C
Step-by-step explanation:
The slope is 1400. And the y intercept is 5000 because when x=0 y=5000. And if you multiply 1400 by 4 and then add 5000 you get 10,600 lbs for the weight at 4 weeks.
The slope is 1400 and the y-intercept is 5000 of the linear equation which is the correct answer would be option (C) y = 1400x + 5000; 10,600 lbs.
What is the slope of the line?The slope of the line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
We have to determine the slope and y-intercept of the linear equation that models this data,
Week Weight (lbs)
0 5000
1 6400
2 7800
3 9200
Slope = (7800 - 6400)/(2 - 1) = 1400
There is a 1400 slope.
And since y=5000 for x=0, the y-intercept is 5000.
So the equation of a baby whale’s weight at 4 weeks is y = 1400x + 5000
Hence, the correct answer would be option (C)

1.) A boy has $12 saved. He decides to start saving on a regular basis. He figures out that he
can
save $1.50 per day. What is the total amount he will have saved after 1 day? 2 days? 3 days?
17days? X days?
Answer:
12 + (1.50 multiplied by x)
Step-by-step explanation:
You have 12 dollars as the base. For every x days (x is the amount of how many days) he'd save $1.50. For one day, he'd save 1.50 plus his 12 dollars. Two days, he'd save 12 + (1.50 x x). Three, it'll be 12 + (1.50 x x) and so on.

If 3x - 8= -2, find the value of x - 6.
Answer:
x-6 = -4
Step-by-step explanation:
3x - 8= -2
Add 8 to each side
3x - 8+8= -2+8
3x = 6
Divide by 3
3x/3 = 6/2
x =2
We want to find x-6
2-6 = -4
Answer: - 4
Step-by-step explanation:
3x - 8 = -2
3x = -2 + 8
3x = 6
x = 6/3
x = 2
so, therefore x - 6 => 2 - 6 = -4

The city of Atlanta plans to hold a parade after the Atlanta Falcons win the Super Bowl. They intend to allow fans to watch from the sidewalk on both sides of Peachtree Street. The parade route will be 1 mile long (5,280 feet are in a mile) and the sidewalks are 10 feet deep. If the average person takes up 3 square feet of space, what is the estimate for the number of people who can attend the parade?
Answer:
17600 people.
Step-by-step explanation:
Given that The parade route will be 1 mile long (5,280 feet are in a mile) and the sidewalks are 10 feet deep.
The area of the parade route will be
5280 × 10 = 52800 ft^2
If the average person takes up 3 square feet of space, then, divide the area by 3. That is,
52800 / 3 = 17600 people.
Therefore, the estimate for the number of people who can attend the parade will be 17600 people.
