A certain type of golfball is tested by a robot that hits the ball with a consistent impact force. The distances this type of ball travels in this test are normally distributed with a mean of 195 meters and a standard deviation of 5 meters. Suppose that quality control experts regularly collect random samples of 25 distance measurements and calculate the sample mean distance in each sample. Assume that the measurements in each sample are independent.
What will be the shape of the sampling distribution of the sample mean distance?
Skewed to the left
(Choice A)
A
Skewed to the left
(Choice B)
B
Skewed to the right
(Choice C)
C
Approximately normal
(Choice D)
D
Unknown; we don't have enough information to determine the shape
Answer:
C Approximately normal
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this question:
Sampling distribution of the sample mean is approximately normal, by the Central Limit Theorem. The correct answer is given by Choice C.

Find the area of the parallelogram.
HELP ME PLS ASAP PLS PLS PLZ
A.160 ft
B. 160ft^2
C. 240 ft
D. 240ft^2
Answer:
A. 160 ft
Step-by-step explanation:
If you look at the picture, you can see that you can move the triangle to the other side of the parallelogram. If you do that, you will just see it is just a rectangle. SO it is 8*20 = 160 ft.

Which of the following statements could be a correct step in solving this equation:
12x−7=13(x−12)
A. 12x−7=13x−12
B. 3x−42=2(x−12)
C. 3x−7=2(x−12)
D. 3x−7=2x−12
Answer:
A
Step-by-step explanation:
I think the answer is A because you have to use 13 to multiply what's in the bracket in order to collect like terms but 13 *12 won't give you 12. That's the reason why am confused

3 * n + 2 = ?
2 * n + 7 = ?
Answer:
1.3n+2
2.2n+7
Step-by-step explanation:
for number 1.you are multiplying 3 and n which gives you 3n but 2 you cant because it dosent have a variable to times with it says plus instead of times.
and for number 2 it the same thing 2 times n equals 2n + 7 is 2n + 7 .

20 points | If you're good at math, please help me with this 9th grade math, thank you <3 kinda running out of time here
Answer:
y = x^2 + 15x + 56
Step-by-step explanation:
The solutions (where the trinomial = 0) is the factors that will turn the trinomial into 010.
(x + 7)(x + 8) = 0
This means that either -7 will turn the trinomial into 0 or - 8 will.
The trinomial is
x^2 + 8x + 7x + 56 will turn the trinomial to 0.
y = x^2 + 15x + 56 when either - 7 or - 8 is put in for x.
y = (-7)^2 + 15(-7) + 56
y = 49 - 105 + 56
49 + 56 = 105
y = 105 - 105 = 0
y = (-8)^2 - 15(-8) + 56
y = 64 - 120 + 56
y = 120 - 120= 0
No other number will turn the trinomial into 0.

Martin needs 3.25 gallons of paint for his small barn and 1.25 gallons of paint for his shed. he spends $81 on paint, how much does the paint cost per gallon?
Answer:
$24.92, $65
Step-by-step explanation:
1. $81 divided by 3.25 = 24.9230769231 = $24.92
2. $81 divided by 1.25 = $64.8, rounded could be $65.
sorry if I'm wrong :).

calculate the perimeter of a quarter circle 2mm use pi=3.14
Answer:
Step-by-step explanation:
If the radius of the circle is 2mm, the circumference is 4π mm.
Arc length of the quarter circle = π mm.
Perimeter of the quarter circle = arc length + 2 radii = 4π + 4 mm = 16.56 mm
What is the coordinates of point A
Answer:
The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane. Recall that the coordinate plane has two axes at right angles to each other, called the x and y axis. The coordinates of a given point represent how far along each axis the point is located.

A quality-assurance worker wants to systematically sample 120 glass jars each day from a conveyor belt in a factory that puts out 3,600 jars each day. If the worker will select every kth jar, what is the best value of k for the worker to use? Enter a whole number.
Answer:
The best value of k for the worker to use is 30.
Step-by-step explanation:
Sample of 120 jars from a set of 3,600.
If the worker will select every kth jar, what is the best value of k for the worker to use?
The best case would be starting at 0 and ending at 3600, finding 120 values, which means that k is given by the division of 3600 by 120. So
[tex]k = \frac{3600}{120} = \frac{360}{12} = 30[/tex]
The best value of k for the worker to use is 30.
