The line of best fit is an illustration of a linear regression
Using the assumed parameters, the value of x when x = 24 is 30.75
How to determine the value of y?The equation of the line of best fit is not given, and the parameters to calculate the line of best fit are missing.
So, I will assume the following parameter values.
Assume that the line of best fit passes through the points
(x,y) = (1,2) and (5,7)
The slope of the line would be:
m = (7 - 2)/(5- 1)
m = 1.25
The equation is then calculated as:
y =m(x - x1) + y1
This gives
y = 1.25(x - 1) + 2
Expand
y = 1.25x - 1.25 + 2
Evaluate
y = 1.25x + 0.75
When x = 24, we have:
y = 1.25 * 24 + 0.75
Evaluate
y = 30.75
Using the assumed values, the value of x when x = 24 is 30.75

Answer: x=20
Step-by-step explanation:
The two angles provided are vertical angles.
Vertical angles are equal in measurement.
This means we can set (3x+50) and (6x-10) equal to each other and solve for x
[tex]3x+50=6x-10[/tex]
Add 10 to both sides
[tex]3x+50=6x-10\\3x+50+10=6x-10+10\\3x+60=6x[/tex]
Subtract 3x from both sides
[tex]3x-3x+60=6x-3x\\60=3x[/tex]
Divide both sides by 3
[tex]\frac{60}{3} =\frac{3x}{3} \\20=x[/tex]
Answer:
Step-by-step explanation:
(3x + 50)° = (6x - 10)°
3x - 6x = -50 - 10
3x = -60
[tex]\frac{-3x}{-3}[/tex] = [tex]\frac{-60}{3}[/tex]
x=20°

Write an eqaution in slope-intercwpt form for the line with slope -5 and y-intercept 9
Answer:
y = -5x + 9
Step-by-step explanation:
Slope-intercept form of an equation is:
y = mx + b
Since they gave you the slope and y-intercept, it is kind of a fill-in-the-blank problem. Nothing to calculate!
Fill in the slope for the m. Fill in the y-intercept for the b.

is planetarium showing programs about the night sky has a shape of a hemisphere. The diameter of the planetarium is 50 ft what is the volume to the nearest cubic foot of the planetarium use 3.14 for pi
Answer:
32,708.3 cu. ft
Step-by-step explanation:
First we find the volume of a sphere with the same dimensions
is the formula for the volume of a sphere
substitute the radius with 25 because radius is half the diameter and use 3.14 for pie. The answer to that formula is 65,416.6
Since you're finding the volume of a hemisphere, divide the volume of the sphere in half
65,416.6/2= 32,708.3
Laurie throws a tennis ball toward her dog from a height of 4.5 ft. The initial vertical velocity of the ball is 18 ft/s. At the same time as Laurie throws the ball, her dog jumps with an initial vertical velocity of 21 ft/s. When the dog jumps, its mouth is 1.5 ft above the ground.
Projectile motion formula:
h = -16t2 + vt + h0
t = time, in seconds, since the ball was thrown
h = height, in feet, above the ground
Which system models the height of the tennis ball and the height of the dog's mouth over time?
h = 4.5t + 18 and h = -16t2 + 1.5t + 21
h = 18t + 4.5 and h =-16t2 + 21t + 1.5
h = -16t2 + 4.5t + 18 and h = -16t2 + 1.5t + 14
h = -16t2 + 18t + 4.5 and h = -16t2 + 21t + 1.5
Using quadratic function concepts, it is found that the system that models the height of the tennis ball and the height of the dog's mouth over time is given by:
h(t) = -16t² + 18t + 4.5 and h(t) = -16t² + 21t + 1.5.
What is the quadratic function for the height of a projectile?It is given by:
h(t) = -16t² + v(0)t + h(0)
In which:
v(0) is the initial velocity.h(0) is the initial height.For the tennis ball, we have that v(0) = 18, h(0) = 4.5, hence the equation is:
h(t) = -16t² + 18t + 4.5.
For the dog jump, we have that v(0) = 21, h(0) = 1.5, hence:
h(t) = -16t² + 21t + 1.5.
Hence, the system is given by:
h(t) = -16t² + 18t + 4.5 and h(t) = -16t² + 21t + 1.5.

The school cafeteria has 16 round tables that each fit-8 students and..
12 rectangular tables that each fit 12 students. How many students can
fit in the cafeteria at once?
A 128
- B 256
C 144
D 272
Answer:
The answer is D. 272
Step-by-step explanation:
All you need to do is find out how many people can be seated at each table, then add them together.
16 x 8 = 128
12 x 12 = 144
128 + 144 = 272
272 students can fit in the cafeteria at once.
Why is it wrong to draw y=ln(2x-5) this way?
well because he did not do it
Notice how
2x-5 = 2x - 2*2.5 = 2(x-2.5)
This means we can replace x with x-2.5 in the second step, in the "wrong way" column.
So,
y = ln(2x)
y = ln( 2(x-2.5) )
y = ln( 2x - 2*2.5 )
y = ln( 2x - 5 )
In the second step, the x-2.5 tells the reader to shift the curve 2.5 units to the right. Therefore, the 1/2 = 0.5 would shift to 0.5+2.5 = 3 as indicated by the correct graph.

A bag contains 15 beads that are either red or yellow.
The probability of randomly removing a red bead is 20%.
What is the probability of randomly removing a yellow bead?
The probability of randomly removing a yellow bead is 0.8 or 80% if the bag contains 15 beads that are either red or yellow the probability of randomly removing a red bead is 20%.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have the probability P(R) of randomly removing a red bead is 20%.
Let's suppose the number of red beads is n(R)
[tex]\rm P(R) = 20\% \Rightarrow 0.20\\\\\rm \frac{n(R)}{15} = 0.20[/tex]
n(R) = 15×0.20
n(R) = 3
Number of yellow beads = 15 -3 = 12
The probability randomly removing a yellow bead:
[tex]=\rm \frac{12}{15}[/tex]
= 0.8 or 80%
Thus, the probability of randomly removing a yellow bead is 0.8 or 80% if the bag contains 15 beads that are either red or yellow the probability of randomly removing a red bead is 20%.

Find the slope of the line passing through the points , 2−6 and , −9−6
I will assume that we are trying to find the slope between (2,-6) and (-9,-6)
The slope's equation ⇒ [tex]\frac{y2-y1}{x2-x1}[/tex]
Let's set the variables:
(x1, y1) --> (2, -6)
(x2, y2) --> (-9, -6)
Now let's plug them in:
[tex]Slope = \frac{-6--6}{-9-2} =\frac{0}{-11} =0[/tex]
Thus the slope of the line is 0.

Elizabeth bought a cheese pizza. It was served on a metal tray with a diameter of 22 centimeters. What is the tray's area?
The Area of the tray ≈380 cm
Solution:We are given the diameter of the tray, which is equivalent to 22 cm.We are asked to find the area of the tray.Remember the formula:Area of a circle = πr²Whereπ -> pi (3.14...)r -> radiusNotice that we aren't given the radius. We're given the diameter only.No reason to panic. We can easily find the radius by dividing the diameter by 2.The radius is equal to 11 cm.Now, plug the values into the formula:A=π(11)²A=121πA≈380 cmHope it helps.

d) 100
Answer:
Step-by-step explanation:
use pythagorean theorem a^2 + b^2 = c^2
a = 6, b = 8
6^2 + 8^2 = c^2
100 = c^2
c = -10
since it cant really be negative, the distance becomes 10.
