Answer:
Because of the distance from the sun to the earth being 2 meters and 25 inches, we can infer that the 1st president of Canada was Ben Franklin. Ben Franklin is on the 7 dollar bill, which means the Illuminati is real. This means the radius of the earth traveling to the sun from mars to jupiter would be a total of 6.96969696969669 milimeters. So in conclusion, yes she was old enough.

Midpoint rule with given value
9514 1404 393
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.

Write the equation in standard form
using factoring.
f(x) = (2x
+
1)(x – 4)
Answer:
2x^2 - 7x - 4
Step-by-step explanation:
Given the expression f(x) = (2x+1)(x – 4)
To write it in standard form, we need to factorize it
(2x+1)(x – 4)
= 2x(x) - 2x(4) + x - 4
= 2x^2 - 8x + x - 4
= 2x^2 - 7x - 4
hence the expression in standard form is 2x^2 - 7x - 4

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+210Find ex and Y to the quadrilateral is a parallelogram.

a) For AQRS use the Triangle Proportionality Theorem to solve for x.
b) After you have solved for x, what is the Perimeter of AQRS?
Answer:
a. x = 14
b. Perimeter = 77
Step-by-step explanation:
a. Based on the Triangle Proportionality Theorem:
[tex] \frac{2x - 2}{13} = \frac{21 - 7}{7} [/tex]
[tex] \frac{2x - 2}{13} = \frac{14}{7} [/tex]
[tex] \frac{2x - 2}{13} = 2 [/tex]
Cross multiply
[tex] 2x - 2 = 2(13) [/tex]
[tex] 2x - 2 = 26 [/tex]
Add 2 to both sides
[tex] 2x = 26 + 2 [/tex]
[tex] 2x = 28 [/tex]
Divide both sides by 2
x = 14
b. Perimeter of ∆QRS = RQ + QS + RS = (2x - 2) + 13 + 17 + (21 - 7) + 7
Plug in the value of x
= (2(14) - 2) + 13 + 17 + 14 + 7
= 26 + 13 + 17 + 14 + 7
= 77

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.
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.

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].

Step-by-step explanation:
If the odds of winning the prize is 1 : 53 and If I purchased 84 tickets what are the odds of winning in percentage. Step by step?
Answer:
79.81% probability of winning.
Step-by-step explanation:
For each ticket, there are only two possible outcomes. Either you win, or you do not. The probability of winning in a ticket is independent of other tickets. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
The odds of winning the prize is 1 : 53
This means that [tex]p = \frac{1}{53}[/tex]
If I purchased 84 tickets what are the odds of winning in percentage.
To win, at least one of the tickets must have the prize, of 84 tickets, so [tex]n = 84[/tex].
We have to find [tex]P(X \geq 0)[/tex], which is given by:
[tex]P(X \geq 0) = 1 - P(X = 0)[/tex]
In which
[tex]P(X = 0) = C_{84,0}.(\frac{1}{53})^{0}.(\frac{52}{53})^{84} = 0.2019[/tex]
[tex]P(X \geq 0) = 1 - P(X = 0) = 1 - 0.2019 = 0.7981[/tex]
79.81% probability of winning.
