Answer: D. The distribution of sample variances tends to be a normal distribution.
Step-by-step explanation:
The properties of the sampling distribution of the variance include:
• The expected value of the sample variance is equal to the population variance.
• The mean of the sample variances is the population variance.
• The sample variances target the value of the population variance.
Therefore, the option that isn't a property of the sampling distribution of the variance will be option D "The distribution of sample variances tends to be a normal distribution".
We should note that the sampling distribution came came in place as a result of the central limit theorem. The sample variance gives a true representation of the variance of the population as it is an unbiased estimator.
The one that does not demonstrate a property of variance's sampling distribution would be:
D). The distribution of sample variances tends to be a normal distribution.
Sampling Distribution PropertyThe variance's sampling distribution property states that:
The variance or the difference of population is equivalent to the sample variance's estimated value.The mean deduced by the sample variances is similar to the difference/variance of the population.The purpose of sample variance aims toward the value denoted by population variance.As per the question, the fourth statement does not exemplify one of its properties as the distribution displayed by sample variances is inclined towards normal distribution.
Thus, option D is the correct answer.

Answer:
24
Step-by-step explanation:
4/5 = x/30, then (4×30)/5 =24
The missing value is 24.
We have,
From the figure,
We can write an expression as:
4:5 = x : 30
This can be written as,
4/5 = x/30
Now,
Cross multiply.
x = 4 x 30 / 5
x = 4 x 6
x = 24

In a factory, a square sheet of metal has of a circle cut from it, as shown. The center of the circle is on one vertex of the square. What is the perimeter of the shaded region to the nearest hundredth?
Answer:
14.28 ft
Step-by-step explanation:
Perimeter of the shaded region = 2(side of the square) + ¼(circumference of circle)
Side of the square = 4 ft
Circumference of circle = 2πr
r = 4
Circumference = 2*π*4 = 25.1327412 ft
✔️Perimeter of the shaded region = 2(4) + ¼(25.1327412) = 14.2831853 ≈ 14.28 ft (nearest hundredth)

A) 30in³
B) V=LWH (or) V+5x3x2
C) V=[tex]\pi[/tex]r²h = [tex]\pi[/tex](2.6²)(4) = 84.94867

a. v = whl
V = (3 in)(2 in)(5 in)
V= 30 in³
b. V = whl
c. Volume of the cylinder = pi(r²)h r = d/2 = 5.2 / 2 = 2.6
Vc = pi (2.6²)(4)

What is an exponential function?
An exponential function is in the form:
y = abˣ
Where a is the initial value of y and b is the multiplication factor.
At x = 0, y = 2, hence a = 2
At x = 1, y = 4, hence:
4 = 2b¹
b = 2
The exponential function is given by:
y = 2(2)ˣ

PLEASE HELP ILL MARK BRAINLY FOR CORRECT ANSWER
Answer:
120 minutes
Step-by-step explanation:
12 x 10 = 120
10 x 12 = 120
15 x 8 = 120
You will put the muffins in 10 times and you will put the cookies in 12 times then you will put the scones in 8 times. If you have different numbers, you can first start out with one number and times all of the numbers by that one number. For example I picked 5 to start out with:
12 x 5 = 60 minutes 10 x 5 = 50 minutes 15 x 5 = 75 minutes.
Then I did 12 x 6 = 72 minutes, 10 x 6 = 60 minutes, 15 x 6 = 90 minutes
Since I still don't have the numbers to add up to the same answer, I went to timing them by 7:
12 x 7 = 84 minutes, 10 x 7 = 70 minutes, 15 x 7 = 105 minutes
They are still not the same answer so lets try 8:
12 x 8 = 96 minutes, 10 x 8 = 80 minutes, 15 x 8 = 120 minutes.
Since I don't want to go farther than 120 minutes, I will keep trying different numbers for the other ones besides 15.
12 x 9 = 108 minutes, 10 x 9 = 90 minutes
12 x 10 = 120 minutes, 10 x 10 = 100 minutes
Now we will focus on getting 10 to 120 because we got 12 to 120.
10 x 11 = 110 minutes
10 x 12 = 120 minutes
To sum all of this, it took 8 trips to get 15 minutes to 120 minutes, 10 trips to get 12 minutes to 120 minutes, and 12 trips to get 10 minutes to 120 minutes.
One more way to think about this is:
10, 12, and 15 can go into 120 evenly.
[tex]12\sqrt{120} = 10[/tex]
[tex]10\sqrt{120} = 12\\15\sqrt{120} = 8[/tex]

Step-by-step explanation:

Solve 4ax + 5ax = 6 ax + 9 for x. Assume a = 0.
Step-by-step explanation:
4ax + 5ax = 6 ax + 9
If a=0
Then
0+0≠0+9
so x is undefined
If the value of 'a' is zero. Then the solution of the equation will be not defined.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
The equation is given below.
4ax + 5ax = 6ax + 9
Simplify the equation for x, then the equation is given as,
4ax + 5ax = 6ax + 9
4ax + 5ax - 6ax = 9
3ax = 9
x = 3 / a
If the value of 'a' is zero. Then the solution of the equation will be
x = 3 / 0
x = not defined
If the value of 'a' is zero. Then the solution of the equation will be not defined.
