Answer:
328
Step-by-step explanation:
For these questions we need to use BODMAS method
B - Brackets
O - Power
D - Division
M - Multiplication
A - Addition
S - Subtraction
First we need to see if there are any brackets
(4 + 3) = 7
After that we need to find if there is any power
- No power
After that we need to find if there is either multiplication or division
23 x 2 = 46
46 x (4 + 3) = 46 x 7 = 322
Now we need to simplify so , we don't get confused
23 x 2 x (4 + 3) x 20 = 322
322 + 6 = 328
We have simplified the answer as much as we can
Answer = 328

Given the following probability distributions:
Distribution C X P{X = Xi)
0 1 2 3 4
0 0.20 0.20 0.20 0.20
Distribution D X P{X = Xi)
0 1 2 3 4
0 0.10 0.40 0.20 0.10
A. Compute the expected value for each distribution.
B. Compute the standard deviation for each distribution.
C. Compare the results of distributions C and D.
Answer:
Step-by-step explanation:
The expected value of this distribution will be the Mean
upon calculation
For the distribution of C
1) P(x=xi) 0 1 2 3 4
0 0.20 0.20 0.20 0.20
[tex]Mean = Pi*xi[/tex]
= 0*0+1*0.2+2*0.2+3*0.2+4*0.2
Mean = 2
2) Standard deviation of C
[tex]\sqrt{(xi-mean)^2 *P(xi)}[/tex]
= 1.09
For the distribution of D
1) P(x=xi) 0 1 2 3 4
0 0.1 0.4 0.2 0.1
[tex]Mean = Pi*xi[/tex]
= 1.9
2) Standard deviation
= 0.984
Upon comparing the result we observe that
C has greater expected value than D
C has greater standard deviation than D which means it is more spreading of the given data than D.

Higher Order Thinking A railroad car container can hold 42,000 pounds. Mr. Evans wants to ship 90 ovens and some freezers in the same container. If each freezer weighs 600 pounds, how many freezers could be shipped in the container? Explain.
The number of freezers that can be shipped depends on the weight of an oven.
Total Weight: 42000 pounds
Weight of 90 ovens: 90w, where w is the weight of each oven.
Remaining weight to fill with freezers: 42000-90w
Weight of each freezer: 600 pounds
# of freezers that could be shipped: Remaining weight / freezer weight = (42000-90w)/600 = 70-3/20w
ANSWER: [tex]70-\frac{3}{20}w[/tex], where [tex]w[/tex] is the weight of each oven

The cost of 1 pound of peanuts will be $2.5.
What is mean by Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The cost of 3 pounds peanuts will be $7.50.
That's mean;
Cost of 3 pounds peanuts = $7.50.
Now,
To find cost of 1 pound of peanuts we can divide $7.50 by 3 as;
Since, The cost of 3 pounds peanuts = $7.50
Hence, The cost of 1 pounds peanuts = $7.50 ÷ 3
The cost of 1 pounds peanuts = $2.5
Thus, Cost of 1 pounds of peanuts is for $2.5.
Therefore, The cost of 1 pound of peanuts will be $2.5

Write the function f(x) = 6x + 5 in terms of z by substituting z for x in the function
Answer:
f(x)=6x+5
You must do this step because the work is asking for it
z=6x+5
Than you change x and z to find z or the inverse of that function
x=6z+5
Subtract-5 both sides
x-5=6z
Divide both sides with 6
(x-5)/6=(6z)/6
Now you simplify
z=(x-5)/6
Done ✅
Step-by-step explanation:
Answer:
f(x) = 6x + 5. To write f(x) in terms of z, substitute the value of x with z:
f(z) = 6z + 5.

What is the y-intercept on this table?
Answer:
the y intercept is 1 at the point (0,1)
Step-by-step explanation:
the y-intercept is when x = 0 because the x-axis is how many you go over, so if you go over none and up or down some, the point lies on the y-axis, and when a point lies on the y-axis, it's the y-intercept.

A company has 2725 employees. Each employee is to be given an ID number that consists of one letter followed by 1 digits. How many different ID numbers are possible
Answer: There are 260 different ID numbers are possible.
Step-by-step explanation:
Given: Each employee is to be given an ID number that consists 1 letter followed by 1 digit .
Number of choices for each letter = 26 [English alphabet consists 26 letters]
Number of choices for each digit = 10
By Fundamental counting principle,
The number of different ID numbers possible = (Number of choices for each letter) x (Number of choices for each digit)
=26 x 10= 260
Hence, there are 260 different ID numbers are possible.
A survey of 50 retail stores revealed that the average price of a microwave was $375 with a sample standard deviation of $20. Assuming the population is normally distributed, what is the 99% confidence interval to estimate the true cost of the microwave
Answer:
The 99% C.I is ( 367.703, 382.297 )
Step-by-step explanation:
Given that:
sample mean [tex]\overline x[/tex] = 375
Population standard deviation [tex]\sigma[/tex] = 20
Sample size n = 50
The level of significance [tex]\alpha[/tex] = 1 - C.I = 1 - 0.99 = 0.01
From z tables:
The critical value = [tex]Z_{\alpha /2}[/tex] = [tex]Z_{0.005}[/tex] = 2.58
The margin of error E = [tex]Z_{\alpha /2}[/tex] [tex]\times \dfrac{\sigma }{\sqrt{n}}[/tex]
The margin of error E = [tex]2.58 \times \dfrac{20}{\sqrt{50}}[/tex]
The margin of error E = 7.297
The limits of 99% C.I are expressed as:
Lower limit = [tex]\overline x - E[/tex] = 375 - 7.297
Lower limit = 367.703
Upper limit = [tex]\overline x + E[/tex] = 375 + 7.297
Upper limit = 382.297
The 99% C.I is [tex]\overline x \pm E[/tex] = [tex]375 \pm 7.297[/tex]
= ( 367.703, 382.297 )
