The required expected value is 13.20.
A box contains bill of = $1, $5, $10, $20, and $100
It costs $14 to reach in and withdraw one bill.
Its estimated value of the variable in probability.
Expected value= mean - 14
= (1+5+10+20+100)/5 -14
= 13.20
Thus, the required expected value is 13.20.

Line M passes through points (4, 2) and (-7, 1) what is the slope of a line N that is parallel to line M
The solution is :
We conclude that the slope of line 'n' is: m₂ = 10
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
Given
The slope of line m is: m₁ = 10
It is stated that another line is parallel to line m.
Let m₂ be the slope of the 'n' line.
We know that when two lines are parallel, they have equal slopes.
i.e. m₁ = m₂
as
The slope of line m is: m₁ = 10
and
The lines are parallel
so
The slope of line 'n' is: m₂ = 10
Therefore, we conclude that the slope of line 'n' is: m₂ = 10.

A business has seven locations to choose from and wishes to rank only the top three locations. How many different ways can this be done?
Answer: 210
Step-by-step explanation:
Given: total locations = 7
Number of locations wishes to rank = 3
If order of selection matters, then the number of permutations of r things from n= [tex]\dfrac{n!}{(n-r)!}[/tex]
The number of ways to rank 3 locations out of 7 [tex]=\dfrac{7!}{(7-3)!}=7\times6\times5=210[/tex]
Hence, the number of different ways required = 210

The product of two consecutive odd integers is 2,915. Build a function that can be used to
solve for the integers. What are the two integers?
The values of the two consecutive odd integers are 53 and 55.
Let the two consecutive odd integers be x and x+2.
Based on the information given, the equation to solve the question will be:
x(x + 2) = 2915
x² + 2x = 2915
x² + 2x - 2915 = 0
x² + 55x - 53x - 2915 = 0
x(x + 55) - 53(x + 55) = 0.
Therefore, x - 53 = 0
x = 0 + 53 = 53
x + 2 = 53 + 2 = 55
Therefore, the numbers are 53 and 55.

Answer:
D
Step-by-step explanation:
Volume of cylinder = Base x height
Base = πr^2 = 25π
Volume = 25π x 10 = 250π
Volume of cone = 1/3 Base x height
= 1/3 x 25π x 5 = 125π/3
Volume of silo = cylinder + cone + cone
= 250π + 125π/3 + 125π/3
= 785.4 + 130.9 + 130.9

Y = -2(x+4) + 6 when x = -2 then use that value of y to evalute w = -3 - 2y
Answer:
12
Step-by-step explanation:
Plug in for x first:
Y = -2(x+4) +6
Y = -2((-2)+4) +6
Y = -4 + 6
Y = 2
Then use Y to find W;
W = -3 -2y
W = -3 - 2(2)
W = -3(-4)
W= 12
Answer:
y=8 and w=13
Step-by-step explanation:
y=-2(x+4)
-2x-2=4 sooo...
y=4+4
y=8
then plug 8 into the equation for w
w=-3-2y
then you would get
w=-3-16
-3-16
w=13
HK bisects GHJ. Find GHK and KHJ. Angle JHG measures 161
Answer: m∠GHK=80.5,
m∠KHJ=80.5
Step-by-step explanation:
Answer:
I would say both GHK and JHK equal 80.5 degrees. (if it is allowed with decimals).
Step-by-step explanation:
Bisectors are lines that basically cut an angle in half. Since JHG is the whole angle, the bisector, HK, halves it. So, both GHK and KHJ should be the same, since they both are half of the original angle. As a result, 161 divided by 2 is 80.5 degrees.
