Using the line of best-fit, it is found that the residual for the player is of 12.6.
What is the residual for a line of best-fit?A residual is given by the difference between the observed point and the predicted point.
In this problem, the expected score over x hours is given by:
f(x) = 280.3 + 85.7x.
Hence, for 3 hours, the predicted score is given by:
f(3) = 280.3 + 85.7 x 3 = 537.4.
The observed score was of 550, hence the residual is given by:
R = 550 - 537.4 = 12.6.

Answer: C
Step-by-step explanation:
By the alternate interior angles theorem, we know that [tex]5y+14=8y-13 \longrightarrow y=9[/tex].
So, this means that [tex]m\angle RPS=59^{\circ}[/tex].
Now, if we consider [tex]\triangle RPS[/tex], since angles in a triangle add to [tex]180^{\circ}[/tex], this means that [tex]59+2x+1+3x=180 \longrightarrow x=24[/tex].
So, [tex]m\angle RSP=\boxed{59^{\circ}}[/tex]
Jackson works at a store and earns $200 each week. He also earns an additional $24 per sale. How
many sales does he need to make so that he earns a minimum of $500 in a week?
Answer:He would have to make a minimum of 13 sales
Step-by-step explanation:
When you divide 300 by 24 you will get 12.5 but you can’t make half a sale so you would have to round up to 13

Liam has a bag that contains pineapple chews, cherry chews, and lime chews. He
performs an experiment. Liam randomly removes a chew from the bag, records the
result, and returns the chew to the bag. Liam performs the experiment 62 times. The
results are shown below:
A pineapple chew was selected 58 times. Based on these results, express the probability that the next chew Liam removes from the bag will be cherry chew as a decimal to the nearest hundredth
A cherry chew was selected 2 times.
A lime chew was selected 2 times.
Based on these results, express the probability that the next chew Liam removes from
the bag will be cherry chew as a decimal to the nearest hundredth
The probability that the next chew Liam removes from the bag will be a cherry chew is 0.03.
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:
Liam performs the experiment 62 times
Total number of outcomes = 62
A pineapple chew was selected 58 times.
A cherry chew was selected 2 times.
A lime chew was selected 2 times.
Now, the probability that the next chew Liam removes from the bag will be cherry chew:
P = 2/62
P = 1/31
P = 0.0322 or 0.03
Thus, the probability that the next chew Liam removes from the bag will be a cherry chew is 0.03.

y=30 and x =25.98
Step-by-step explanation:
Solving For Y value:
Sin30 = 15/y
0.5 = 15/y
y0.5 = 15
y = 15 / 0.5
y=30
Solving For X value:

Recycling Center #1 charges $0.75 per visit but lets you use their equipment for free. Recycling Center #2 charges you $0.25 per visit and $5.00 to use their equipment. How many times would you need to visit the recycling center for the total cost to be the same?
Answer:
10 times
Step-by-step explanation:
We have two separate equations that represent this situation:
0.75x ----> which represents recycling center #1
0.25x + 5.00 -----> which represents recycling center #2
To find the amount of times you would need to visit the recycling centers for the total cost to be the same, put both of these equations equal to each other:
0.75x = 0.25x + 5.00
Now, solve:
0.75x = 0.25x + 5.00 Subtract 0.25x from 0.75x
0.50x = 5.00 Divide 5.00 by 0.50
x = 10
Thus, you would need to visit the recycling centers 10 times for the total cost to be the same.
Let's check this answer by plugging 10 into both equations:
0.75(10) = 7.5
0.25(10) + 5.00 = 7.5
Since both of the answers are the same, then 10 is the correct answer!

The angle 01, is located in Quadrant II, and cos(01) = -12/19
What is the value of sin(01)?
Answer:
sqrt(217)/19
Step-by-step explanation:
Ok so insead of using 01 as the angle ill use x. cos(θ) is the the x-value of the point on the unit circle, while sin(θ) is the y value. cos(x) here is -12/19. By constructing a triangle such that one of the verticies is at (-12/19, sin(x)), we know the x distance is -12/19, and the hypotenues is 1, because it's a unit circle. sqrt(1-144/361)=sqrt(217/361)=sqrt(217)/19. the y value must e positive because this point lays in the 2nd quadrant.

The distance from point P to the foot of the flagpole is 13.42m. So, The height of the flagpole will be 17.7 m.
What are the six trigonometric ratios?Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.
In a right-angled triangle, two such angles are there which are not right-angled(not of 90 degrees).
The slanted side is called the hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.
We know that
[tex]tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}[/tex]
Let x be the distance from point P to the foot of the flagpole.
So, From point P the height h of the flagpole will be
[tex]tan(53) = \dfrac{height}{x}\\\\tan(53) x = h\\\\h = 1.32x[/tex]
From point Q, the height h will be
[tex]tan(28) = \dfrac{height}{20+x}\\\\tan(28) (20+x )= h\\\\h = 0.53 (20+x )[/tex]
From both values of h, we get
x = 13.42
Put the value of x in the first value of h,
h = 1.32 ( 13.42)
h = 17.7
Hence, the height of the flagpole will be 17.7 m.
