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

Answer:

The expression that describes the width of Kevin’s yard is (3g + 12) feet

Step-by-step explanation:

This is an expression problem.

From the question, we are made to know that the width of the yard is 3 times the width of the garage increased by 12 feet.

Now, we are told that the width of the garage is g feet and we want to find the width of the yard.

The width of the yard will be g feet * 3 + 12

Mathematically that would be 3g + 12 feet

Answer:

It is fair.

See the chart?

On all coins, there is a 50/50 chance it will be wrong or right.

There are 6 sides.

Half of them are H, and the other half T.

So, there are 3 heads and 3 tails.

3 to 3 is equal, so it is fair.

Hope this helped :)!

Step-by-step explanation:

Step 1

Compute the sum of the given options

a)  11 . 38 + 4 . 03 = 15.41

b) 10 + 5 . 41= 15.41

c) 12 . 38 + 2 . 93= 15.31

d) 9 . 2 + 6 . 21 =15.41

e) 7 . 54 + 6 . 87=14.41

Step 2

Eliminate the expressions that do not give a sum of 15.41 , we have

a)  11 . 38 + 4 . 03 = 15.41

b) 10 + 5 . 41= 15.41

d) 9 . 2 + 6 . 21 =15.41

Therefore, the expressions with sum of 15.41  are A, B  and D

All you must do is find the correct values in the graph.

The graph which is generated by the table of values x -5,-3,-1,4 and y=2,4,1,0 is on coordinate plane points are at (-5,2) ,(-3,4) ,(-1,1) ,(4,0).

A function is a relationship between two or more variables having each value of x corresponding to y values. Values of x are known as domain and values of y are known as codomain.

We have been given the following table as under:  

  x                           y

 -5                          -3

 -3                           4

 -1                           1

   4                           0

We have to plot the points -5 ,-3,-1,4 on x axis and corresponding-3,4,1,0 on y-axis.

Hence the graph of given table of values is that on coordinate plane points are at (-5,2) (-3,4)(-1,1)(4,0).

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.

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).

Answer:

7/15

Step-by-step explanation:

For me, it is easier to take the 3/5 and put it in decimal form which is .6 and add the 5 to it, making 5.6, and then in a calculator put in 5.6 divided by 12 and you should get a big decimal that's pretty big but if you have a graphing calculator and convert that to a fraction and you should get 7/15, This is a pretty lazy way of me doing it but that's how I did it.

Answer:

2

Step-by-step explanation:

A commutative function means that when you insert one function in space of x in the other function, they will equal x. The equation is f(g(x)) = g(f(x)) = x

So, 2([tex]\frac{x+1}{a}[/tex]) - 1 = [tex]\frac{(2x-1)+1}{a}[/tex]

If you multiply both sides by a, you get   2a([tex]\frac{x+1}{a}[/tex]) - a = (2x-1)+1

Simplify it                                                   2a([tex]\frac{x+1}{a}[/tex]) - a = 2x

Add a to both sides                                    2a([tex]\frac{x+1}{a}[/tex])  = 2x +a

The two as on the left cancel out                   2(x+1)=2x+a

Distribute the 2                                               2x+2=2x+a

Then subtract 2x from both sides                        2 = a

Therefore, a = 2

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.

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.

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.
