Isaac creates a scatter plot showing the association between the height and weight of his male
classmates. He models the association with the equation w = 6.5h - 275, where h is the
classmate's height in inches and w is the classmate's weight in pounds. What is the meaning of the
slope in this equation?
Answer:
Step-by-step explanation:
Given
w is the classmate's weight in pounds
h is the height
The general formula for the expression is y = MX+c where
m is the slope
c is the intercept
M is the change in y to change in x
Comparing with the given equation
w = 6.5h - 275, we will see that the slope of the equation is 6.5 and can be expressed as the change in the classmate's height to the classmate's weight
slope = dh/dw = 6.5

For this question the average height of adult women is 63.7” with a sigma of 2.9”. The US Navy requires that fighter pilots have heights of between 62 and 78 inches. Find the approximate percentage or women who qualify to be fighter pilots. HINT: Drawing a distribution curve may help.
Answer:
72%
Step-by-step explanation:
For this question the average height of adult women is 63.7” with a σ of 2.9”. The US Navy requires that fighter pilots have heights of between 62 and 78 inches. Find the approximate percentage or women who qualify to be fighter pilots. HINT: Drawing a distribution curve may help.
Find the z-scores.
z = (x − μ) / σ
z₁ = (62 − 63.7) / 2.9
z₁ = -0.586
z₂ = (78 − 63.7) / 2.9
z₂ = 4.93
Use a chart or calculator to find the probability.
P(-0.586 < Z < 4.93) = P(Z < 4.93) − P(Z < -0.586)
P(-0.586 < Z < 4.93) = 1.000 − 0.279
P(-0.586 < Z < 4.93) = 0.721
Approximately 72% of women will qualify.
If the Navy changes its height requirement to include all but the shortest and tallest 3% of the female population, what would the new height requirements for women be? HINT: Drawing a distribution curve may help. Also, rounding is suggested.
In this case, we work in reverse. Use a chart or calculator to find the z-score for each probability.
P(Z < z₁) = 0.03
z₁ = -1.881
P(Z > z₂) = 0.03
P(Z < z₂) = 0.97
z₂ = 1.881
Now find the heights associated with those z-scores.
z = (x − μ) / σ
-1.881 = (x₁ − 63.7) / 2.9
x₁ = 58.2
1.881 = (x₂ − 63.7) / 2.9
x₂ = 69.2
The new height requirement is between 58.2" and 69.2".
need help to determine if it's a undefined slope or it is a slope of line and what's the answer please and thank you
Answer:
It is slope of a line which is 4
Step-by-step explanation:
We are given that the given points are generated by a linear function. A linear function is ta straight line that can be represented by:
[tex]y = mx+b[/tex]
Here m is the slope
The slope of a line is given by the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
In order to find the slope from the table we take any two pairs of inputs and outputs i.e. x and y
So here we take
(x1,y1) = (-6,-16)
(x2,y2) = (-5,-12)
Putting the values in the formula
[tex]m = \frac{-12-(-16)}{-5-(-6)}\\m = \frac{-12+16}{-5+6}\\m = \frac{4}{1}\\m = 4[/tex]
Hence,
It is slope of a line which is 4
4.) What is the area of this shape?
Answer:
Its blurry, can you take another picture?
Step-by-step explanation:
Answer:
1456 square unitsStep-by-step explanation:
The shape can be considered as the combination of a square with the side of 28 and a triangle with base of (28 + 10 + 10) and the height of 28
Then the area of the shape is:
28*28 + 1/2*48*28 = 784 + 672 =1456 square unitsWhat is the circumference
Answer:
In geometry, the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.
Step-by-step explanation:
Answer:
1. Circumference = 87.92
2.Circumference = 43.96
Step-by-step explanation:
The first problem it had a radius. So in order to find the circumference you will have to use the formula 2πr. When you plug in the 14 yd in the radius spot it will look like 2π(14) when you solve it the answer will be 87.92
The second one has a diameter so the equation you will have to use is πd. Now you will have to plug the 14 cm where the diameter is which will look like π(14) when you solve it the answer will come out as 43.96

Calculate 1 + 3 + 5 +...+ (2n - 1) for several natural numbers n.
Answer:
The solutions for 1 + 3 + 5 +...+ (2n - 1), for the first 10 natural numbers are given in the explanation section below.
Step-by-step explanation:
To calculate 1 + 3 + 5 +...+ (2n - 1) for several natural numbers n, we will use several natural numbers to represent n.
For n= 1,
2n - 1 = 2(1) - 1 = 2 - 1 = 1
Hence, 1 = 1
For n = 2,
2n - 1 = 2(2) - 1 = 4 - 1 = 3
Hence, 1 + 3 = 4
For n = 3,
2n - 1 = 2(3) - 1 = 6 - 1 = 5
Hence, 1 + 3 + 5 = 9
For n = 4,
2n - 1 = 2(4) - 1 = 8 - 1 = 7
Hence, 1 + 3 + 5 + 7 = 16
For n = 5,
2n - 1 = 2(5) - 1 = 10 - 1 = 9
Hence, 1 + 3 + 5 + 7 + 9 = 25
For n = 6,
2n - 1 = 2(6) - 1 = 12 - 1 = 11
Hence, 1 + 3 + 5 + 7 + 9 + 11 = 36
For n = 7,
2n - 1 = 2(7) - 1 = 14 - 1 = 13
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49
For n = 8,
2n - 1 = 2(8) - 1 = 16 - 1 = 15
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 = 64
For n = 9,
2n - 1 = 2(9) - 1 = 18 - 1 = 17
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 = 81
For n = 10,
2n - 1 = 2(10) - 1 = 20 - 1 = 19
Hence, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 100

Part B:Identify the domain in range of the function.
Answer:

Step-by-step explanation:
the table shows the same time I don't have your phone you u you y you can get a hold of y have a lot to do it you got a
The domain and range provides a definition for a graph
Part A: The graph represents a function because a vertical line drawn from the horizontal crosses the graph only once
Part B. Domain: 0 ≤ t ≤ 30
Range: 7000 < f(t) ≤ 9,300
Reason:
Part A: The reason why the graph represents a function is that a function is a one to one relationship that maps each element of the set known as the domain to exactly one element of the set which is the range of the function
Therefore, a vertical line drawn on the graph of a function crosses the graph only once, such that one input cannot have two outputs
Which gives that the graph is a function, given that all the vertical lines from the horizontal axis crosses the graph f(t) at exactly one point
Part B
Domain:
The domain of a function are the possible input values of the function
In the graph, the possible values of the time, t are; 0 ≤ t ≤ 30
The domain of the function is 0 ≤ t ≤ 30
Range:
The range of a function are the possible output values of the function
The range of the given function f(t) are; from approximately 7,000 feet to approximately 9,000 feet, which gives;
The range of the function: 7000 < f(t) ≤ 9,300

B) The total amount of snow that falls in d days when there's already 5 inches of snow on the ground.
C) The total amount Andrew saves when he saves $24 a week for w weeks.
D) The length in x months of a baby that grows 2 inches per month and was born 7 inches long.
Using the concept of proportionality, it is found that these following situations represent proportionality:
A) The total amount a babysitter makes who earns $10 an hour for babysitting r hours.
C) The total amount Andrew saves when he saves $24 a week for w weeks.
In a proportional relationship, the output y is given by the input x multiplied by a constant k, that is:
[tex]y = kx[/tex].
Thus, when x = 0, y = 0.In this problem:
In options A and C, when the input is 0, the output is also 0, thus they are proportional.In option B, when the input is 0 days, the output is 5 inches of snow, thus it is not proportional.In option D, when the input is of 0 months, the height is of 7 inches, thus also not proportional.A similar problem is given at https://brainly.com/question/22846068
