If x, the time (in minutes) to complete an oil change job at certain auto service station, is uniformly distributed over the interval 20 to 30, then what is the probability that an oil change job is completed in less than or equal to 22 minutes?
Answer:
The value is [tex]P(X \le 22) = 0.2[/tex]
Step-by-step explanation:
From the question we are told that
The lower limit of the interval is [tex]a = 20[/tex]
The upper limit of the interval is [tex]b = 30[/tex]
Generally the cumulative distribution function for uniform distribution is mathematically represented as
[tex]F(x) = \left \{ {{0 \ \ \ \ \ \ \ \ \ \ \ for x < a } \atop {\frac{x - a}{b-a} \ \ \ \ \ \ for a \le x \le b }} \atop { 1 \ \ \ \ \ \ \ \ \ \ \ for x > b}\right.[/tex]
Generally the probability that an oil change job is completed in less than or equal to 22 minutes is mathematically represented as
[tex]P(X \le 22) = \frac{22 - 20}{30 - 20 }[/tex]
=> [tex]P(X \le 22) = 0.2[/tex]

Same question as previous parts. The working is identical, using different numbers.
Focus-vertex distance is (y-difference) p = -4-(-5) = 1. Vertex is (h, k) = (2, -5). Putting these values into the vertex form and expanding to standard form, you get ...
y = (1/(4p))(x -h)^2 +k
y = 1/4(x -2)^2 -5 . . . . . . . . fill in the values for p, h, k

What is the rate change of the linear function that has a graph that passes through the points (2,9) (-1,3)
The linear function is y = 3x + 6. Then the rate of change of the linear function will be 3.
What is differentiation?The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.
The linear equation that is passing through the points (2,9) and (-1,3).
Then we have
y - 3 = [(3 - 9)(-1 - 2)] (x + 1)
y - 3 = (-6) / (-2) (x + 1)
y - 3 = 3x + 3
y = 3x + 6
Then the rate of change of the linear function will be
y' = 3

What is the measure of angle A in the triangle?
Answer:
Angle A = 50°
Step-by-step explanation:
(2x - 10) + (x + 30) + 70 = 180
3x = 180 + 10 - 30 - 70
3x = 90
x = 90/3
x = 30
A = 2x -10
A = (2 * 30) - 10

Which of the following systems of equations is an example of one where substitution is the best method?
A.)5x+3y=15

B.)y=2/7y+11
3x-4y=-24
C.)4x-5y=20
-6x+2y=-42
D.)x=4
Y=11
Answer:
B
Step-by-step explanation:
B is the best example where substitution is the best method since you already have one where y = something and you can plug -2/7x + 11 into the bottom equation for y and solve it that way. A and C make you get x or y by itself first first substitution would work and D already gives you the answers. B is the best since its already set in that format.

What is the approximate volume of water in Anju's cup?
Answer:
V = 167.55
Step-by-step explanation:
V = pir^2 h/3
V = pi(4)^2 (10/3)
The approximate volume of water in Anuj's cup is 42 cubic cm.
What is volume?Volume is a measure of capacity that an object holds.

According to the given question
paper cups are of the shape of cone.
and,
diameter = 8cm
⇒ radius = [tex]\frac{8}{2}[/tex] = 4cm
the approximate volume of water in cup = [tex]\frac{1}{3} \pi r^{2} h[/tex]

Step-by-step explanation:
∆VWZ ~ ∆VXY, therefore:
[tex] \frac{VW}{VX} = \frac{VZ}{VY} [/tex]
VW = 8
VX = 8 + WX
VZ = 18
VY = 27
Plug in the values
[tex] \frac{8}{8 + WX} = \frac{18}{27} [/tex]
Cross multiply
[tex] 8 * 27 = (8 + WX)*18 [/tex]
[tex] 216 = 144 + 18WX [/tex]
Subtract 144 from each side

Cecily is comparing two checking accounts. Checking account A has a monthly fee of $16 and a per-check fee of $0.08, while checking account B has monthly fee of $14 and a per-check fee of $0.12. She want to know how many checks she would need to write per month for the accounts to charge the same amount in fees.
Part III: What equation can be set up to solve for the number of checks Cecily would need to write per month for the accounts to charge the same amount in fees?
Part IV: How many checks would Cecily need to write per month for the accounts to charge the same amount in fees?
Part 3
Checking account A has a monthly fee of $16 and a per-check fee of $0.08
If she writes x checks, where x is some nonnegative whole number, then she is charged an additional 0.08x dollars on top of the 16 dollar fee.
The total cost of checking account A is 0.08x+16 dollars.
The total cost of account B is 0.12x dollars for similar reasoning. We don't have a monthly fee, but the cost per check is higher.
Set the two expressions equal to one another to get your answer.
Answer: 0.08x+16 = 0.12x
==============================================
Part 4
Let's solve the equation we set up in part 3
0.08x+16 = 0.12x
16 = 0.12x-0.08x
16 = 0.04x
0.04x = 16
x = 16/0.04
x = 400
If Cecily wrote 400 checks per month, then the cost of each account would be the same.
For account A, it would cost her 0.08*x+16 = 0.08*400+16 = 48 dollars
For account B, it would cost her 0.12*x = 0.12*400 = 48 dollars.
Answer: 400 checks per month

The function g is defined by the following rule. g(x) = 5x +1
The table for the function is,
x -3 -2 1 4 5
g(x) -14 -9 6 2 26
What is a function?A mathematical phrase, rule, or law establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
Given a function g(x) = 5x + 1
to find the values of g(x) for given values of x
when x = -3
g(x) = 5x + 1
g(-3) = 5(-3) + 1
g(-3) = -14
when x = -2
g(-2) = 5(-2) + 1
g(-2) = -9
when x = 1
g(1) = 5(1) + 1
g(1) = 6
when x = 4
g(4) = 5(4) + 1
g(4) = 21
when x = 5
g(5) = 5(5) + 1
g(5) = 26
Hence the values for g(x) are -14, -9, 6, 21, and 26 respectively.

Michael has credit card debt of $75,000 that has an 12% APR, compounded monthly. The minimum payment only the requires him to pay the interest on his debt. He receives an offer for a credit with an APR of 4% compounded monthly. If he rolls over his debt onto his card and makes the same monthly payment as before, how long will it take him to pay off his credit card debt?
Answer: 122 months.
Step-by-step explanation: The first step is to calculate the minimum monthly payment using the debt balance of $75,000 and 12% APR compounded monthly,which = $75,000 × 12% / 12 = $750 . The second step is to use the same $750 as payment, and using a discount rate of 4%/12, calculate the number of months required to pay off the present value (PV) of $75,000 , which = 122 months.
