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.

what is of the area of circle with a circumference of 12.56 feet?
Answer:
π= 25.12 , r=6.28
area of a circle = πr²
= 25.12×6.28²
= 25.12×39.4
= 990.6cm²
Step-by-step explanation:
circumference of a circle is 2π
radius of a circle is 2π/4

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

Step-by-step explanation:
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
2. Write the equation of the line parallel to y = -4x/3 + 5 thru (-6,1). Show all work.
Answer:
[tex]\boxed {\boxed {\sf y= - \frac{4}{3} x -7}}[/tex]
Step-by-step explanation:
We can find the equation using the point-slope formula.
[tex]y-y_1=m(x-x_1)[/tex]
where (x₁, y₁) is the point and m is the slope.
We already know the point is (-6,1). We must find the slope.
We are told the line is parallel to y=-4x/3 +5. Since this line is in y=mx+b form, the slope (m) must be -4/3. Parallel lines have equal slopes, so the line we are finding also has a slope of -4/3
Next, define values for the variables.
[tex]x_1= -6 \\y_1= 1\\m= - \frac{4}{3}[/tex]
Substitute the values into the formula.
[tex]y-1= - \frac{4}{3} (x--6)[/tex]
[tex]y-1= - \frac{4}{3} (x+6)[/tex]
Now put the equation into the form y=mx+b. First, distribute the -4/3 .
[tex]y-1= - \frac{4}{3} *x+ - \frac {4}{3}*6[/tex]
[tex]y-1= - \frac{4}{3} x - 8[/tex]
Add 1 to both sides to isolate y.
[tex]y-1+1= - \frac{4}{3} x - 8+1[/tex]
[tex]y= - \frac{4}{3} x -7[/tex]
The equation of the line is y=-4/3x -7

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%
