[tex]E(x) = 4.56[/tex] --- Mean
[tex]s^2 = 1.0944[/tex] --- Variance
[tex]s = 1.0461[/tex] --- Standard Deviation
Step-by-step explanation:
See Comment for missing details
Given
[tex]p = 0.76[/tex] --- proportion
[tex]n = 6[/tex] -- sample
Solving (a): The mean; E(x)
This is calculated as:
[tex]E(x) = n * p[/tex]
Substitute values for n and p
[tex]E(x) = 6 * 0.76[/tex]
[tex]E(x) = 4.56[/tex]
Solving (b): The variance; s^2
This is calculated as:
[tex]s^2 = n*p*(1-p)[/tex]
Substitute values for n and p
[tex]s^2 = 6 * 0.76 * (1-0.76)[/tex]
[tex]s^2 = 6 * 0.76 * 0.24[/tex]
[tex]s^2 = 1.0944[/tex]
Solving (c): The standard deviation; s
This is calculated as:
[tex]s = \sqrt{s^2[/tex]
Substitute value for s^2
[tex]s = \sqrt{1.0944[/tex]
[tex]s = 1.0461[/tex]

What is the area of JKLM?
Answers
Answer: 96in.^2
Step-by-step explanation:
Ok so first we need to find the missing width of figure NPQR and we can do that by dividing the area by the length to solve for height. so 294/21 is 14 so the missing side of NPQR is 14. With me so far? now since these figures are similar lets find out how similar. so 21/12= 1.75 so JKLM increased in dilation by 1.75 to get to NPQR. So now that we found the missing side from NPQR we can divide that by 1.75 to find the missing side of JKLM now. So 14/1.75= 8. So 8 is the missing side of JKLM. Now all we have to do is multiply. So 8*12= 96 or 96in.^2

3. Add to both sides 10k -16 +16 = 10k, -3k-39 + 16 = -3k-24, 10k = -3k-24
4. Add to both sides with variable
10k + 3k = 13k, -3k-24+3k = -24

Colton has 888 comedy movies, 666 action movies, 555 fantasy movies, and 111 drama movie on his list of favorite movies. For every 555 movies on the list, there are 222 \_\_\_\_____\_, \_, \_, \_ movies.
Answers
Answer: Comedy
Step-by-step explanation:
Find out the percentages of each of the movies. First find the total quantity.
= 888 + 666 + 555 + 111
= 2,220 movies
Comedy = 888/2,220 * 100% = 40%
Action = 666 / 2,220 * 100% = 30%
Fantasy = 555/2,220 * 100% = 25%
Drama = 111/ 2,220 * 100% = 5%
222 movies out of 555 is:
= 222 / 555 * 100%
= 40%
222 movies out of 555 movies will therefore be comedy.
Answer:
222/555 are comedy

Consider the triangle below.
Determine the angle measure for the bottom two angles in order for the triangle to be classified as an isosceles triangle.
Answers
Answer:
angle 1= 30 degrees
angle 2= 120 degrees
angle 3= 30 degrees
Step-by-step explanation:
A triangle is equal to 180 degrees so first step is to subtract 120 to get the total of your two missing angles
180-120=60
and since your two missing angles are equal to each other you can divide by 2 and you get your two missing angles
60 / 2 = 30
A cell phone provider offers a plan that costs $40 per month plus $0.20 per text message sent or received. A comparable plan costs $70 per month but offers unlimited text messaging.
Answers
Answer:
For, 250 messages the plans cost the same. Under 250 messages, plan A is cheaper.
Step-by-step explanation:
Giving the following information:
Plan A:
Fixed costs= $40
Variable cost= $0.2
Plan B:
Fixed cost= $40
I assume that we have to determine the indifference point, where the two plans cost the same.
First, we need to establish the total cost equations
Plan A= 20 + 0.2x
Plan B= 70
x= number of messages
Now, we equal both formulas and isolate x:
20 + 0.2x = 70
0.2x= 50
x= 250
For, 250 messages the plans cost the same. Under 250 messages, plan A is cheaper.

The first three terms of a geometric sequence are as follows.
2, 10, 50
Find the next two terms of this sequence.
Answers
Answer:
250, 1250
Step-by-step explanation:
Since 10/2 = 50/ 10 = 5, the common ratio = 5 So the next term in the sequence is found by multiplying the last term by 5.
Therefore, 50 x 5 = 250 and 250 x 5 = 1250. So, the next two terms in your sequence are 250 and 1250

The enrollment at a university increased from 1,000 students to 6,000 students over a 6-year period. What was the percent increase in enrollment over that time period?
Answers
Answer: 500%
Step-by-step explanation:
The percent increase is calculated as:
= (New number of students - Old number of students) / Old number of students * 100%
= (6,000 - 1,000) / 1,000 * 100%
= 5 * 100%

The value of y when the value of x is equal to the negative number 4 is negative 11 (-11).
What is an unknown variable?Unknown variables are used to find the unknown values of the problem using the algebraic expressions.
The expression for the variable x and y are given as,
[tex]y=2x-3[/tex]
The x value for the above expression is given as,
[tex]x=-4[/tex]
The value of y for the above value of x has to be found out. Put the value of x in the given expression to find the value of variable y as,
[tex]y=2(-4)-3[/tex]
