The table above gives values of a function f at selected values of x. Which of the following
conclusions is supported by the data in the table?
can you add the table to the question?
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.

Step-by-step explanation:
If Mark can make 42 birthday cakes in 7 days that means he can make 6 cakes a day. Multiply this by 5 and you get 30
Answer:
30 cakes
Step-by-step explanation:
42 divided by 7 is 6 so the math you would do is 5 times 6 which 30 and the subject is cakes do the answer is 30 cakes.
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.
How can I interpret the remainder? Give two examples of interpreting the remainder in different ways.
Answer:
Sometimes you only use the quotient.
Another way is to add 1 to the quotient. Situations when it is necessary to include all items.
Other times you will only use the remainder.
One way is to write the remainder as a fraction.
Step-by-step explanation: These are some ways you can interpret the remainder

10n + 10(7n + 10) = -10(11 - n)
Answer:
n = -3
Step-by-step explanation:
P E M D A S
10 x 7n = 70n
10 x 10 = 100
10n + 70n + 100 = -10(11 - n )
80n + 100 = -10(11 - n )
80n + 100 = 10n - 110
80n + 100 - 100 = 10n - 110 - 100
80n = 10n - 210
80n - 10n - 10n - 210 - 10n
70n = -210
70n ÷ 70 = -210 ÷ 70
n = -3

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.

Step-by-step explanation:
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.
