Answer:
124.77
Step-by-step explanation:
Matthew opened a checking account with 150
On Monday he bought lunch for 9.30 and wrote a check for 25.75
He deposited 75 on Wednesday
On thursday 65.18 was deducted from the account for his car insurance
The total expenses incurred on Monday can be calculated as follows
=9.30+25.75
= 35.05
This means that 35.05 will be debited from his account
On wednesday, he made a deposit of 75, this implies that a credit will be made to his checking account
On thursday, 65.18 was removed from his account for car insurance
Therefore since the initial balance of the account was 150 then, the remaining money that will be left in his account can be calculated as follows
= 150-35.05+75-65.18
= 124.77
Hence the money remaining in Matthew's account is 124.77
Answer:
The answer is 124.77

Which of the following is an odd function??
O g(x) = x2
O g(x) = 5x - 1
O g(x) = 3
O g(x) = 4x
Step-by-step explanation:
An odd function is where g(x) = -g(-x).
Therefore the answer is g(x) = 4x, as it passes through the origin and g(x) is positive when x is positive, and g(x) is negative when x is negative.
The odd function will be g(x) = 4x. Then the correct option is D.
What is an odd function?A true function f(x) is said to be an odd function if the output value of f(-x) is the same as the negative of f(x) for all values of x in the domain of f.
The equation should be stored in an odd function:
f(-x) = -f(x)
Let's check all the options.
A. The function is g(x) = x².
Substitute x = -x, then we have
g(x) = (-x)²
g(x) = x²
This is an even function.
B. The function is g(x) = 5x – 1.
Substitute x = -x, then we have
g(x) = 5(–x) – 1
g(x) = – (5x + 1)
This is a neither even nor odd.
C. The function is g(x) = 3.
Substitute x = -x, then we have
g(x) = 3
This is an even function.
D. The function is g(x) = x.
Substitute x = -x, then we have
g(x) = -x
g(x) = x
This is an odd function.
Then the correct option is D.

Cynthia besch wants to buy a rug for a room that is 20 ft wide and 33 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 378 ft² of carpeting. What dimensions should the rug have?
Answer:
Length of rug = 14 ft
Width of rug = 27 ft
Step-by-step explanation:
Given:
Length of rug = 20 ft
Width of rug = 33 ft
Area she afford = 378 ft²
Find:
New sides
Computation:
Assume;
Uniform strip = x
So,
Length of rug = 20 - x ft
Width of rug = 33 - x ft
Ares = l × b
[20-x][33-x] = 378
660 - 20x - 33x + x² = 378
x² - 53x + 282
x² - 47x - 6x + 282
x(x-47) -6(x-47)
So,
x = 6 and x = 47
X = 47 not be taken, So x=6
Length of rug = 20 - 6 ft
Width of rug = 33 - 6 ft
Length of rug = 14 ft
Width of rug = 27 ft

Step-by-step explanation:
look at the image and show work 4) translation: 6 units left K, J, I, L
Answer:
K (-5, 2); J (-2, 3); I (-1, 1); L (-5, -3)
Step-by-step explanation:
Translating the shape 6 units to the left means that every point/vertex will be moved 6 units to the left of where it is originally drawn.
Point K is at (1, 2). Since we are only moving it left (on the x-axis), the y value will not change. To move K left 6, we have to subtract 6 from its current x-value, 1. We get -5 for the new x-value. Because the y value didn't change, the new location of K is (-5, 2).
Point J is at (4, 3). Subtracting 6 from 4 (the x value) gives us the new x value of -2. Again, the y value does not change and so our new location for J is (-2, 3).
Point I is at (5, 1). If we subtract 6 from 5, we get -1. This is our new x value for I. The new point is (-1, 1). (Once again, the y value does not change).
Point L is at (1, -3). By subtracting 6 from the original x value, 1, we get our new x value: -5. The new point for L is (-5, -3).
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

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.

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.

The question is incomplete:
Irene's grandfather arrived in Sydney from Athens at 10 pm on Friday after a 25-hour trip. The flight began at 12 noon on Thursday, Athens time. What is the time difference between Athens and Sydney?
A. Athens time is 9 hours behind Sydney time.
B. Athens time is 9 hours ahead of Sydney time.
C. Athens time is 15 hours behind Sydney time.
D. Athens time is 15 hours ahead of Sydney time.
Answer:
A. Athens time is 9 hours behind Sydney time.
Step-by-step explanation:
The statement indicates that the flight began at 12 noon on Thursday, Athens time and that it lasted 25 hours. So, you can calculate the Athens time when he arrived after 25 hours which would be 1 pm on Friday. Also, the statement says that Irene's grandfather arrived in Sydney at 10 pm on Friday and now we know that at that moment it was 1 pm on Friday, Athens time. From these, you can calculate the difference between 1 pm and 10 pm that would be 9 hours. Because of this, the answer is that the time difference between Athens and Sydney is that Athens time is 9 hours behind Sydney time.

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 :)
