The weights of gala apples follow a Normal distribution with a mean of 140 grams and a standard deviation of 12 grams. The owner of an apple orchard randomly selects 5 apples from the harvest and records the mean weight. What is the shape of the distribution of the sample mean for all possible random samples of size 5 from this population?
Answer:
The shape is approximately normal, with mean of 140 grams and standard deviation of 5.37 grams.
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.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
What is the shape of the distribution of the sample mean for all possible random samples of size 5 from this population?
By the Central Limit Theorem, the shape is approximately normal.
Mean is [tex]\mu = 140[/tex]
Standard deviation is [tex]s = \frac{12}{\sqrt{5}} = 5.37[/tex]
The shape is approximately normal, with mean of 140 grams and standard deviation of 5.37 grams.

5. Can two fractions point to the same location on the number line? Explain.
Answer:
1 2 = 2 4 = 3 6 = 4 8 = etc. All of these fractions are located at the same point on the number line. Therefore, they represent the same number. From the paper folding exercises, we see that increasing both numerator and denominator of a fraction by the same factor gives an equivalent or equal fraction.

Answer:
4/3
10/3
24/3
...........
Answer:
4/3
10/3
24/3 or 8
Step-by-step explanation:
x = y - 2/3
2 - 2/3 = 2/1 - 2/3 = 6/3 - 2/3 = 4/3
y = x + 2/3
8/3 + 2/3 = 10/3
y = x + 2/3
22/3 + 2/3 = 24/3 = 8

On Monday, a local hamburger shop sold a combined total of 544 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the
number of hamburgers sold. How many hamburgers were sold on Monday?
Answer:
136 hamburgers
Step-by-step explanation:
Create an equation where x is the number of hamburgers sold.
The number of cheeseburgers sold can be represented by 3x, since it was 3 times the number of hamburgers.
3x + x = 544
Solve for x:
4x = 544
x = 136
So, 136 hamburgers were sold on Monday

Okay, so.. y'know those angle thingys? Like.. how they have a circle in the corner of let's say a triangle or a little square in the corner of it? What are those called and what's their degrees?
Answer:
im pretty sure it's called a right angle or right angle quadrant
Step-by-step explanation:
if it's a square in a corner of a triangle then it is a right angle and the degrees would be 90

Answer:
150 degrees and 30 degrees
Step-by-step explanation:
Let's say the measure of the angle is x. This angle is 5 times that of its supplementary, supplementary angles will add up to 180 degrees. So we have an equation of x = 5(180-x). Solve this equation for x
x = 5(180-x)
x = 900 - 5x
6x = 900
x = 150 degrees, this is the value of one angle
The other angle is 180-x = 180-150 = 30 degrees

- 1 - (-10)
D4=(27) = -1-(-10)
4 - 8
Answer:
its b
Step-by-step explanation:
The proportion that can be used to show that the slope of JL is equal to the slope of MP is (0 - 4)/(-4 - (-7)) = (-4 - 8)/(-1 - (-10))
How to determine the proportion that can be used to show that the slope of JL is equal to the slope of MP?From the question, we understand that triangle MNP and triangle JKL are similar right triangles.
This means that triangle MNP and triangle JKL have the same slope
From the figure, we have the following coordinates of the triangles
J = (-7, 4)
L = (-4, 0)
M = (-10, 8)
P = (-1, -4)
The slope is calculated as
Slope = (y2 - y1)/(x2 - x1)
So, we have
JL = (0 - 4)/(-4 - (-7))
Also, we have
MP = (-4 - 8)/(-1 - (-10))
Equate both equations
So, we have
(0 - 4)/(-4 - (-7)) = (-4 - 8)/(-1 - (-10))
Hence, the proportion that can be used to show that the slope of JL is equal to the slope of MP is (0 - 4)/(-4 - (-7)) = (-4 - 8)/(-1 - (-10))

A ball is tossed at a hole in a board. The ball goes into the hole 15 times and misses the hole 52 times.
Based on this experiment, what is the probability that the ball will go into the hole when tossed?
Enter your answer in the box as a percent rounded to the nearest whole number.
Probability (Ball goes into hole) = 0.22388 or 22.388%
Step-by-step explanation:
Given:
Ball goes into hole = 15 times
Ball miss the hole = 52 times
Find:
Probability (Ball goes into hole)
Computation:
Total number of tries = 15 + 52
Total number of tries = 67
Probability (Ball goes into hole) = 15 / 67
Probability (Ball goes into hole) = 0.22388 or 22.388%
