The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.We have 64 3/4.
First change the mixed fraction into normal fraction as

Determine the value of y that maintains the congruence of the figures.
Answer:
We conclude that the value of y = 11 cm.
Step-by-step explanation:
Given that both the figures maintain the congruence of the figures. It means both the figures have the same size.
Thus,
The length of DQ = The length of EL
Given
The length of DQ = 3y - 1
The length of EL = 32 cm
so
The length of DQ = The length of EL
3y - 1 = 32
Adding 1 to both sides
3y - 1 + 1 = 32+1
3y = 33
Dividing both sides by 3
3y/3 = 33/3
y = 11
Thus, the value of y = 11 cm
Therefore, we conclude that the value of y = 11 cm.

The cost of a breakdown is $2,000, and the cost of a preventive maintenance program is $2,000 per month. If the preventive maintenance program is adopted, the probability of a machine breakdown is negligible. How much better off per month would the firm be if it adopted preventive maintenance
This question is incomplete, the complete question is;
Suppose that for a particular piece of machinery, the frequency distribution of monthly breakdowns is as follows;
Number of breakdowns prob.
0 0.50
1 0.25
2 0.10
3 0.10
4 0.05
The cost of a breakdown is $2,000, and the cost of a preventive maintenance program is $2,000 per month. If the preventive maintenance program is adopted, the probability of a machine breakdown is negligible. How much better off per month would the firm be if it adopted preventive maintenance
Answer:
the firm will be $100 worse off per month if it adopted preventive maintenance.
Step-by-step explanation:
Given the data in the question;
the probability of breakdown iwill be;
= (0×0.5) + (1×0.25) + (2×0.10) + (3×0.10) +(4×0.05)
= 0 + 0.25 + 0.2 + 0.3 + 0.2 = 0.95 or 95%
Now the cost of machine failure will be;
⇒ 2000 × 0.95= $1900
if they implemented preventive measures, the cost is $2000,
if the preventive measure taken the cost is $2000, the benefit is for $1900, and the output is additional cost of $100.
Therefore the firm will be $100 worse off per month if it adopted preventive maintenance.
Midpoint rule with given value

Answer:
M₅ = 1.6570
Step-by-step explanation:
The basic idea is to find the function values at x ∈ {1.1, 1.3, 1.5, 1.7, 1.9}, add those values, and multiply the result by 1/5. Those x-values are the midpoints of intervals 0.2 units wide, between x = 1 and x = 2. The width 0.2 is the total interval width (2-1=1) divided by n = 5.
The calculation and results are shown in the attachment. Rounded to 4 decimal places, the integral is ...
M₅ = 1.6570
__
The actual integral is about 1.6574, so this is pretty close.

A triangle with coordinates (1, 1), B(4, 2). C1(3, 5) is translated three units down and five units to the left. What are the coordinates of the new triangle?
Your answer should be B.
Explanation: Moving left or right affects the x coordinate, and moving up or down affects the y coordinate.
Moving 3 units down: A(1, 1 - 3), B(4, 2 - 3), C(3, 5 - 3) = (1, -2), (4, -1), (3, 2)
Moving 5 units to the left: A(1 - 5, -2), B(4 - 5, -1), C(3 - 5, 2) = A(-4, -2), B(-1, -1), C(-2, 2)
(Sorry I said A, earlier.)
At the beginning of the year Monica puts a set amount of money into her health benefit account. Every month she withdraws $15 from this account for her contact lenses. After 3 months she has $255 left in her account.
Write an equation in slope-intercept form to represent the relationship between the time that has passed and the amount of money left in Monica's account. Let x represent the time in months and y represent the amount of money remaining in the account.
Answer:
An equation in the slope-intercept form will be:
y = 15x+210Step-by-step explanation:
We know The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptLet x represent the time in months
Let y represent the amount of money remaining in the account.
Given that every month Monica withdraws $15 from this account for her contact lenses
Thus, the rate of change or slope = m = 15
Given that after 3 months she has $255 left in her account.
So, we take the point (3, 255)
substituting m = 15, x = 3 and y = 255 in the slope-intercept form to determine the y-intercept
y = mx+b
255 = 15(3) + b
switch sides
15(3) + b = 255
45 + b = 255
b = 255 - 45
b = 210
Now, substituting m = 15 and b = 210 in the slope-intercept form of the line equation
y = mx+b
y = 15x+210
Therefore, an equation in the slope-intercept form will be:
y = 15x+2101. Solve 2/3 X 4/5

An art teacher mixes 5 parts blue paint and 3 parts white paint to make a light blue color to paint a Tar Heels logo on a school mural. If she needs a total of 40 gallons of light blue paint to paint the mural, how many gallons of blue paint will she use?
Answer:
50
Step-by-step explanation:
For starters, we make the following assumptions
Let the blue paint be represented by x
Let the white paint be represented by y
Now, forming an inequality equation from the question, we can say that
5x + 3y = 1
And from the second part, we are told that 40 gallons of light blue paints are needed.
If 5x + 3y = 1, then multiplying all by 40, we have
200x + 120y = 40
This means that 200 parts of blue paints is needed to be mixed with 120 parts of white paints to get the desired 40 gallons.
There are 4 parts in a gallon, so 200 parts = 200/4 gallons, = 50 gallons of blue paints

Which of the following inequalities is graphed on the coordinate plane?
O A. y > -21 + 1
OB. y -23 + 1
OC. y < -25 + 1
OD. y < -23 + 1
Answer: D. y ≤ -2x = 1
Step-by-step explanation: To determine the inequality, first determine the line equation.
Line equation can be written as
[tex]y-y_{0}=m(x-x_{0})[/tex] , called point-slope form of a line equation,
where
m is slope of the equation
x₀ and y₀ are points in the line
Slope is calculated as the difference between y-coordinates divided by the difference between the x-coordinates:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
From the graph, we have 2 points: (-1,3) and (1,-1), so find slope:
[tex]m=\frac{3+1}{-1-1}[/tex]
m = -2
Replacing slope and point (0,1) into point-slope form:
[tex]y-1=-2(x-0)[/tex]
[tex]y=-2x+1[/tex]
This is the equation of the line.
Now, we determine the inequality:
Observe the graph, if the line is a continuous one, it is a less-than-or-equal-to (≤) or more-than-or-equal-to (≥). If it was a dotted line, the symbol would be less-than (<) or more-than (>).
In our case, the line is continuous so it will be ≥ or ≤. To determine which one, we can plug a point located in the shaded part, for example (0,0). Substituting:
y = -2x + 1
0 ≠ -2(0) + 1
0 ≤ 1
Therefore, line equation of the graph is [tex]y\leq -2x+1[/tex].
16. Which statement best describes a margin of error?
A. the difference between a sample mean and a population proportion
B. the value of error between a sample mean and a population proportion
C. the difference between a sample mean and a population mean
D. the value of error between a sample statistic and an actual population parameter
Answer: D. the value of error between a sample statistic and an actual population parameter
Step-by-step explanation:
In a study , the margin of error gives the amount of the random variation of the actual result from its estimation.
So, it is the value of error between a sample statistic( which is estimated population parameter until actual is known) and an actual population parameter.
Hence, the best statement to represent the margin of error :
D. the value of error between a sample statistic and an actual population parameter
