The graph represents the cost of renting a generator from a hardware store. What does the point (2, 50) mean in the problem situation?

Answer:

B

Step-by-step explanation:

the are of the square would be: 4*6=24

the are of one triangle would be: (6*2)/2=6 (12 in total because there are two triangles

to find the whole area, you add 24 and 12 which is B) 36 meters squared

The rule that can be used to describe the x-coordinates in the translation is (x+6).

A translation is a sort of transformation that moves each point in a figure in the same direction by the same amount of distance.

We know that the coordinate is moving up, therefore, the coordinate of x will be increasing by 6 units.

Hence, the rule that can be used to describe the x-coordinates in the translation is (x+6).

1 minute = 0.25km

Step-by-step explanation:

divide both numbers that were given by 8. 8÷8 is 1 and 2÷8 is 0.25.

The difference between the mean of the two sets is 1, which is half the Mean absolute deviation.

The mean absolute deviation is the average distance between the data points and the mean of the data set.

A.) For the data set M, {0, 1, 3, 4, 7}, the mean and the mean absolute deviation can be written as,

[tex]\text{Mean of M}, (\mu_M) = \dfrac{0+1+3+4+7}{5} = 3[/tex]

The mean absolute deviation of the set M,

[tex]MAD = \dfrac{1}{n}\sum_{i=0}^{n}|x_i-m(x)|[/tex]

[tex]MAD = \dfrac{1}{5}\sum_{i=0}^{5}|x_i-m(x)|\\\\MAD_M= \dfrac{10}{5} = 2[/tex]

Now, since the MAD of the set M is 2, therefore, the data points in Set M that are closer than one mean absolute deviation from the mean are 3 because the range of the one mean absolute deviation from the mean,

Mean±MAD

= 3±2

= 3+2, 3-2

= 5, 1

Thus, the numbers coming between 1 to 5 are the data points that are closer than one mean absolute deviation which is 3{1, 3, 4}.

B.) For the data set N, {1, 2, 3, 4, 5, 9}, the mean and the mean absolute deviation can be written as,

[tex]\text{Mean of N}, (\mu_N) = \dfrac{1+2+3+4+5+9}{6} = 4[/tex]

The mean absolute deviation of the set N,

[tex]MAD = \dfrac{1}{n}\sum_{i=0}^{n}|x_i-m(x)|[/tex]

[tex]MAD = \dfrac{1}{6}\sum_{i=0}^{6}|x_i-m(x)|\\\\MAD_m= \dfrac{12}{6} = 2[/tex]

Now, since the MAD of the set N is 2, therefore, the data points in Set N that are further than two mean absolute deviations from the mean of Set are 3 because the range of the one mean absolute deviation from the mean,

Mean±2MAD

= 4±2(2)

= 4+4, 4-0

= 8, 0

Thus, the number not coming between 8 to 0 are the data points that are further than two mean absolute deviations from the mean of Set N which are 1{9}.

C.) The difference between the mean of the two sets is 1, which is half the Mean absolute deviation.

If the Thompsons need the movers for more than 6 hours, City movers would be the better deal. Therefore, option D is the correct answer.

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.

Given that, the Thompson family was moving and hired Town Movers to move them for a fee of $30 plus $15 per hour.

Let the number of hours be x.

Now, 30+15x

Movers called and offered a fee of $72 plus $8 an hour, which they thought might be a better deal

72+8x

From the graph, both the movers have same charge at 6th hour and City movers charge is decreasing then compare to Town Movers.

Therefore, option D is the correct answer.

Answer:

Lin is taller than 150 centimeters but shorter than 160 centimeters. She could be ... (just put any number that is in between 150 and 160, like 155

Step-by-step explanation:

Answer:

lin is taller than 150

But shorter than 160

She could be 154 centimeters tall

The sign > means greater than.

The sign < means less than.

So, if h > 150, h is greater than 150

And, if h < 160, h is less than 160

h represents Lin

So, lin is taller than 150

But shorter than 160

She could be anywhere in between 150 and 160

So, she could be

151, 152, 153, 154, 155, 156, 157, 158, or 159

Answer:

n-5=2n+9

Step-by-step explanation:

The value of x for which this model will make the least sense to use is at x=-2.75 seconds.

A function assigns the value of each element of one set to the other specific element of another set.

The function that is given to us is h(x) = –16x²+100 where x is the time in seconds.

Now, use the function to know the height of the object, therefore, the height of the object can be written as,

Time, t₁=0

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(0)=0+100\\\\h_1=100[/tex]

Thus, the height of the object when the time is 0 seconds is 100.

Time, t₂=0.5

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(0.5)=-4+100\\\\h_2=96[/tex]

Thus, the height of the object when the time is 0.5 seconds is 96.

Time, t₃=1

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(1)=-16+100\\\\h_1=84[/tex]

Thus, the height of the object when the time is 1 second is 84.

Time, t₄=1.5

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(1.5)=-36+100\\\\h_4=64[/tex]

Thus, the height of the object when the time is 1.5 seconds is 64.

Time, t₅=2

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(2)=0+100\\\\h_5=36[/tex]

Thus, the height of the object when the time is 2 seconds is 36.

Now as we can see that the error in the height of the object can be a maximum of 1, therefore, for different values of x, the change in height will be,

Time, t₆= -2.75

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(-2.75)=-121+100\\\\h_6= -21[/tex]

Thus, the height of the object when the time is -2.75 seconds is -21.

Hence, the value of x for which this model will make the least sense to use is at x=-2.75 seconds.

Answer:

1.375 in decimal form

Step-by-step explanation:

The value of x is 17.6. She should have added 5.4 on both sides to get the correct value of x. Then the correct option is A.

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Kaitlyn solved the equation for x using the following calculations.

[tex]\rm -5.4 + x =12.2[/tex]

and she did the calculation will be

[tex]\rm -5.4x = 6.8[/tex]

The mistake she did in this equation is the plus sign is removed between the -5.4 and x. And she subtracted 5.4 from 12.2.

The correct solution of the equation is to add both sides 5.4. Then we have

[tex]\begin{aligned} \rm -5.4 + x+5.4 &=12.2+5.4\\\\\rm x &= 17.6\end{aligned}[/tex]

Hi! Hope you are having a nice day!

Yes, the square of a rational number is always positive.

We know that a negative times a negative equals a positive only.

Well, a negative squared also equals a positive.

For example, (-4)² is equal to 16.
