The solution is $ 9.50
The weekly per hour rate of Tasha is $ 9.50
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The weekly per hour of Tasha last week = $ 422.75
The extra overtime pay of Tasha for 3 hours = $ 42.75
The total number of hours working = 40 hours
So , the equation will be
The weekly per hour of Tasha without overtime = weekly per hour of Tasha last week - overtime pay of Tasha for 3 hours
Substituting the values in the equation , we get
The weekly per hour rate of Tasha without overtime = 422.75 - 42.75
The weekly per hour of Tasha without overtime = $ 380
So , The weekly per hour rate of Tasha A = The weekly per hour rate of Tasha without overtime / total number of hours working
Substituting the values in the equation , we get
The weekly per hour rate of Tasha A = 380 / 40
The weekly per hour rate of Tasha A = $ 9.50
Therefore , the value of A is $ 9.50
Hence , The weekly per hour rate of Tasha is $ 9.50

The question is incomplete. Here is the complete question.
Nite Time Inn has a toll-free telephone number so that customers can call at any time to make a reservation. A typical call takes about 4 minutes to complete, and the time required follows an exponential distribution. find the probability that a call takes
a) 3 minutes or less
b) 4 minutes of less
c) 5 minutes of less
d) Longer than 5 minutes
e) Longer than 7 minutes
Answer: a) P(X<3) = 0.882
b) P(X<4) = 0.908
c) P(X<5) = 0.928
d) P(X>5) = 0.286
e) P(X>7) = 0.174
Step-by-step explanation: Exponential distribution is related with teh amount of time until some specific event happens.
If X is a continuous random variable, probability is calculated as:
[tex]P(X<x) = 1-me^{-mx}[/tex]
in which:
m is decay parameter, given by: [tex]m=\frac{1}{mean}[/tex]
For the Nite Time Inn calls:
[tex]m=\frac{1}{4}[/tex]
m = 0.25
(a) P(X<3)
[tex]P(X<3) = 1-0.25e^{-0.25.3}[/tex]
[tex]P(X<3) = 1-0.25e^{-0.75}[/tex]
[tex]P(X<3) = 1-0.25*0.472[/tex]
P(X < 3) = 0.882
The probability the call takes less than 3 minutes is 0.882.
(b) P(X<4)
[tex]P(X<4) = 1-0.25e^{-0.25.4}[/tex]
[tex]P(X<4) = 1-0.25e^{-1}[/tex]
P(X < 4) = 0.908
The probability the call takes less tahn 4 minutes is 0.908.
(c) P(X<5)
[tex]P(X<5) = 1-0.25e^{-0.25.5}[/tex]
[tex]P(X<5) = 1-0.25e^{-1.25}[/tex]
P(X < 5) = 0.928
The probability of calls taking less than 5 minutes is 0.928.
(d) P(X>5)
Knowing that the sum of probabilities of less than and more than has to equal 1:
P(X<x) + P(X>x) = 1
P(X>x) = 1 - P(PX<x)
[tex]P(X>x) = 1-(1-me^{-m*x})[/tex]
[tex]P(X>x)=me^{-mx}[/tex]
For P(X>5):
[tex]P(X>5) = 0.25e^{-1.25}[/tex]
P(X > 5) = 0.286
The probability of calls taking more than 5 minutes is 0.286.
(e) P(X>7)
[tex]P(X>7)=0.25e^{-0.25.7}[/tex]
[tex]P(X>7)=0.25e^{-1.75}[/tex]
P(X > 7) = 0.174
The probability of calls taking more than 7 minutes is 0.174.

Simba loans $2,000 to his buddy Timon to teach hula lessons.
Timon is having trouble balancing his books and winds up losing $500 a month
after starting up his business. Pumba is helping Timon calculate how much debt
he will be in after one year if he doesn't make any changes. What should he use
for the y-intercept? What should he use for the rate of change?
Answer:
y-intercept: 2000rate of change: 500Step-by-step explanation:
When Timon starts, he is already $2000 in debt. If we represent Timon's debt with positive numbers, the y-intercept will be $2000.
Timon's debt seems to be increasing at the rate of $500 per month. That value is the rate of change.
After m months, Timon's debt d will be ...
d = 500m + 2000
If c(x)= 4x - 2 and d(x)= x^2 + 5x what is ( c • d ) ( x )?

A rectangular plot of ground having dimensions 26 feet by 30 feet is surrounded by a walk of uniform width. If the area of the walk is 240 feet squared, what is its width?
Answer:
2 ft
Step-by-step explanation:
Given that Dimensions of rectangular plot are: 26 feet by 30 feet
Length is 26 ft
Width is 30 ft
Area of rectangle = Length [tex]\times[/tex] Width
So, area of given rectangular field is = 26 [tex]\times[/tex] 30 = 780 sq ft
Let the width of the walk = [tex]x[/tex] ft
Kindly refer to the attached image for the given scenario.
Dimensions of the plot with walk = (26+2[tex]x[/tex]) ft by (30+2[tex]x[/tex]) ft
So, area of plot without walk = 780 sq ft
Area of walk = Area with walk - Area of plot
Now, we are given that area of walk = 240 sq ft
So, we get:
240 = (26+2[tex]x[/tex]) [tex]\times[/tex] (30+2[tex]x[/tex]) - 840
[tex]\Rightarrow (26+2x)(30+2x)=780+240\\\Rightarrow 780+4x^2+112x=780+240\\\Rightarrow 4x^2+112x-240=0\\\Rightarrow x^2+28x-60=0\\\Rightarrow x^2+30x-2x-60=0\\\Rightarrow x(x+30)-2(x+30)=0\\\Rightarrow x = 2, -30\ ft[/tex]
[tex]x[/tex] can not be negative, so [tex]x = 2\ ft[/tex]
So, the width of the walk = 2 ft

Subtract (3 + 2i) from (–9 – 8i).
–17 – 5i
–6 – 6i
–12 – 10i
12 + 10
Answer:
-12 - 10i
Step-by-step explanation:
We are subtracting 3 + 2i from -9 - 8i. Rewrite the left side as -3 - 2i and then ADD this result to -9 - 8i:
-9 - 8i
-3 -2i
-----------
-12 - 10i
Answer:
-9-8i)-(3+2i)
= -9-8i-3-2i
Separate i and the numbers
= (-9-3)+(-8i-2i)
= -12-10i

I have to find the slope and the y-intersect from these graphs. It would mean alot if someone could help with at least one of them, or teach me how to solve these.
Answer:
Alright bear with me, this is gonna be a long one.
The Y INTERCEPT
So the y-intercept is going to be where the line intersects the Y-AXIS. The y-axis is the vertical part of the graph with the numbers on it.
So, for the first one, the line goes through the origin which means that that the y intercept is going to be (0,0)
The next one, the line intersects the y-axis at (0,1)
Here's a tip: the y-intercept will always have 0 as it's x coordinate.
The Slope
Alright, the slope of a vertical line can be found using an equation. Most typically people will describe the slope as RISE/RUN meaning how many units you move up "rise" and how many units you move horizontally "run" to touch the line. Of course, it's easier when you can identify points.
So to make this a little bit easier to understand, I will show you how to use the equation to find the slope.
[tex]\frac{y2-y1}{x2-x1}[/tex]
So for this equation, what you need is two coordinates. So for the first graph, I'm going to use the points (0,0) and (1,3)
[tex]\frac{3-0}{1-0}[/tex]
So we make the three y2 because it's the second y coordinate and the y1 would be 0. Same applies to the x coordinates but use the x values.
the slope for the first graph would be 3/1
FOR THE SECOND GRAPH
[tex]\frac{y2-y1}{x2-x1}[/tex]
Here's our equation now pick two points. I'll be using (-5,4) and (0,1)
[tex]\frac{1-4}{0-(-5)}[/tex]
Don't forget that a negative-a negative = positive
which will leave you with
[tex]\frac{-3}{5}[/tex]
since it can't be simplified any further, your slope is -3/5.
I hope I was able to help you understand this a bit better :)

Point I is on line segment HJ. Given I J equals 3X +3, HI equals 3X-1, and HJ equals 3X +8, determine the numerical length of HJ.
Answer:14
Step-by-step explanation:
3x + 3 + 3x - 1 = 3x + 8
6x + 2 = 3x + 8
3x + 2 = 8
3x = 6
x = 2
HJ= 3(2) + 8 =6 + 8 = 14
HI= 3(2) - 1 = 6 - 1 = 5
IJ = 3(2) + 3 = 6 + 3 = 9
The numerical value of the length HJ such that will be I J equals 3X +3, HI equals 3X-1, and HJ equals 3X +8 will be 14.
What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
Given that the line HJ has a length of 3x+8
HJ = 3x+8
The line segment HI has a length of 3x -1
HI = 3x -1
The line segment IJ is 3x + 3
IJ = 3x + 3
Since line HJ = HI + IJ
3x -1 + 3x + 3 = 3x+8
x= 2
The length of HJ will be
HJ = 3(2) + 8
HJ = 14 hence, 14 will be the correct answer.
