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

The Thompson family was moving and hired Town Movers to move them for a fee of $30 plus $15 per hour. City Movers called and offered a fee of $72 plus $8 an hour, which they thought might be a better deal. The family made a graph of the two offers. When would City Movers be the better deal?
Answers
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.
What is the graph?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.

Kaitlyn solved the equation for x using the following calculations. Negative 5. 4 x = 12. 2. Minus 5. 4. X = 6. 8. What error, if any, did she make? She should have added 5. 4 to each side. She should have added the inverse of 5. 4 to each side. She made a computational error when she subtracted 5. 4 from 12. 2. She should have added 12. 2 to each side.
Answers
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.
What is the linear system?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]

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

Step-by-step explanation:
Given expression: (9w² + 7w - 2) + (8w² - 8w - 7) - (-5w² + 5w + 4)
Step-1: Open the parenthesis
⇒ (9w² + 7w - 2) + (8w² - 8w - 7) - (-5w² + 5w + 4)⇒ 9w² + 7w - 2 + 8w² - 8w - 7 + 5w² - 5w - 4Step-2: Combine like terms
⇒ 9w² + 7w - 2 + 8w² - 8w - 7 + 5w² - 5w - 4⇒ w²(9 + 8 + 5) + w(7 - 8 - 5) + (-2 - 7 - 4)Step-3: Simplify the expression
⇒ w²(9 + 8 + 5) + w(7 - 8 - 5) + (-2 - 7 - 4)⇒ w²(22) + w(-6) + (-13)⇒ 22w² - 6w - 13Therefore, the simplified expression is 22w² - 6w - 13.
Given Set and Set. Calculate the mean and mean absolute deviation for both sets. Then, answer the following questions. How many data points in Set are closer than one mean absolute deviation from the mean of Set ? How many data points in Set are further than two mean absolute deviations from the mean of Set ? Find the difference between the two means. How does this difference relate to the mean absolute deviation of each set? For example, is it the same as the mean absolute deviation, twice as much, half as much, etc?.
Answers
The difference between the mean of the two sets is 1, which is half the Mean absolute deviation.
What is 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.

We know that:
To find the area of a circle, use πr².Since the sprinkler sprays water 4 feet in all directions, the radius will be 4 ft.
This means that:
Area of circle = (3.14)4²Now, let's solve for the area.
