Answer:
Explanatory variable (independent variable)
The variable that affects the other variable.Drawn along the horizontal axis.Response variable (dependent variable)
The variable that is being affected. Drawn up the vertical axis.(a) As the class wondered if they could predict the father's height, when they know the son's height
Explanatory variable = son's height
Response variable = father's height
(even though this is contrary to real-life, where the father's height would be used to predict the son's height)
(b) **see first attachment**
(c) The association is positive since the father's height increases as the son's height increases.

Answer:
closed circle means 10 is a possible answer
m is greater or equal to 10
it's the 1st and 4th options
Step-by-step explanation:
Answer:
m ≥ 10 and it's a closed circle that is a possible answer.
Step-by-step explanation:
Rules:
Open circle: < (going left) or > (going right)
Closed circle: ≤ (going left) or ≥ (going right)
Here, we have a closed circle at 10, going right (≥).
Therefore, the correct answers are: m ≥ 10 and it's a closed circle that is a possible answer.
This means that m is equal to 10, or any value that is greater than 10.

. It took Erin the same time to drive 21 miles as it took Brent to drive 15 miles. Erin's speed was 10 mph
faster than Brent's speed. How fast did Erin drive?
The speed at which Erin drove from the given parameters was calculated as; 35 mph
How to work with speed rates?
Let Erin's speed rate be X. Now, since it took erin 21 miles, then;
Erin's time = 21/X
Now, erin's speed was 10 mph faster than Brent's speed. Thus;
Brent's speed = (X - 10) mph
Thus, Brents time = 15/(x - 10)
Now, since they took the same time, then we know that;
21/x = 15/(x - 10)
15x = 21x - 210
6x = 210
x = 210/6
x = 35
Thus, Erins speed = 35 mph

Taharka, Lamari and Keyon are sharing the cost of a football. Taharka will pay 0.15 of the cost. Lamari
will pay 12 of the cost. Keyon will pay the rest. If the football costs $16, how much will they each pay?
Answer:
the answer should be 3.85 that they pay each
Step-by-step explanation:
Because if you add 12.15 (Taharka + Lamari) and 3.85, it equals 16. The 3.85 comes from 16.00 - 12.15
The area of a rectangle is 56 cm. The length is 2 cm more then x and the width is 5 cm less than twice x. Solve for x. ROund to the nearest whole number.

A rectangle's length is 3 times its width. If the perimeter is 32, what is the area?
Please answer the question correctly and with a good explanation. Please and thank you
Answer:
48
Step-by-step explanation:
To calculate the area of a composite shape you must divide the shape into rectangles, triangles, or other shapes you can find the area of and then add the areas back together. You may have to calculate missing lengths before finding the area of some of the shapes.
I split it into a square and a trapezoid
The area of the square is 6x5 = 30
The area of the trapezoid is
A=a+b
2h=3+6
2·4=18
So add the area together
30+18= 48

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 7/1 is 1/7) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, cancel by a common factor of 3 gives 8/
7
.
In other words - twenty-four thirds divided by seven = eight sevenths.
Divide: the result of step No. 1 : 5 = 8/7 : 5 = 8/7 · 1/5
= 8 · 1/7 · 5
= 8/35
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 5/1

Answer:
x = 22.6 degrees
Step-by-step explanation:
The triangle is a right triangle which means that you can use trigonometry to find the values for each angle.
cos(x) = opposite / hypotenouse.
So cos(x) = 12/13.
You can then solve using a calculator and find that the angle is 22.6 degrees.
The equation d = 11 cosine (startfraction 8 pi over 5 endfraction t) models the horizontal distance, d, in inches of the pendulum of a grandfather clock from the center as it swings from right to left and left to right as a function of time, t, in seconds. according to the model, how long does it take for the pendulum to swing from its rightmost position to its leftmost position and back again? assume that right of center is a positive distance and left of center is a negative distance. 0.625 seconds 0.8 seconds 1.25 seconds 1.6 seconds
The time it take for the pendulum to swing from its rightmost position to its leftmost position and back again is 1.25 seconds.
What is time period of pendulum?Pendulum is the body which is pivoted a point and perform back and forth motion around that point by swinging due to the influence of gravity.
The time period of pendulum is time taken by it to complete one cycle of swing left to right and right to left.
The equation models the horizontal distance of the pendulum of a grandfather clock from the center as it swings from right to left and left to right as a function of time, t, is given as,
[tex]d = 11 \cos\left( \dfrac{8\pi}{5}t\right)[/tex]
At the maximum position, the time period is zero. Thus,
[tex]\dfrac{8\pi}{5}t=0\\t=0[/tex]
At the minimum position, the period equal to the π. Thus,
[tex]\dfrac{8\pi}{5}t=\pi\\t=\dfrac{5}{8}\\t=0.625[/tex]
This time is for one side of motion. The time for swing from its rightmost position to its leftmost position and back again is,
[tex]t=0.625+0.625\\t=1.25\rm\; s[/tex]
Thus, the time it take for the pendulum to swing from its rightmost position to its leftmost position and back again is 1.25 seconds.

Maddy has a coupon for bananas. Bananas normally
cost $0.49 per pound. Maddy wants to buy 8
pounds of bananas for her team. She has a coupon
for 5 cents off per pound.
If she uses the coupon, how much will she pay?
Answer:
$3.52
There are two ways you can solve this problem.
1. Take 5 cents off before multiplying.
Since the coupon takes 5 cents off per pound, you can subtract 5 cents off 49 cents.
$0.49-$0.05= $0.44
Now multiply $0.44 by the 8 pounds.
$0.44 (8) = $3.52
2. Take the 5 cents off after multiplying
You can multiply the 5 cents by 8, to find the total money off the bananas. Then subtract that from the total cost.
$0.49 (8) = $3.92 -> Total cost with no coupon
$0.05 (8) = $0.40 -> Total money off
Subtract the two totals.
$3.92 - $0.40 = $3.52
