To compute the test statistic :
We need the sample mean and sample standard deviation :
15.87, 16.02, 15.78, 15.83, 15.69, 15.81, 16.04, 15.81, 15.92, 16.10
Using calculator :
Sample mean, m = 15.887
Standard deviation = 0.13
Test statistic :
(m - μ) / s/sqrt(n)
(15.887 - 16) / 0.13/sqrt(10)
-0.113 / 0.0411096
= - 2.749
Tcritical at 95%
Tn-1, 0.025
T10,0.025 = 2.262
Since the test statistic value is less than the critical value, reject H0

Carter went shopping for a new pair of pants. Sales tax where he lives is 3.75%. The
price of the pair of pants is $36. Find the total price including tax. Round to the
nearest cent.
Answer:
$37.35
Step-by-step explanation:
You find the sales tax by turning 3.65% to 0.0375. Then you multiply that by 36. Then you will get 1.35. You add 1.35 to 36 and get your answer of $37.35.
Which of the following is not a function
{(-1,-2), (0, -3),(1,-2), (2,1)}
{(-1,-2), (0, -3), (1, -2), (2, 1)
{(-2, 2), (-1,1),(0,0),(1,1)}
{(-2,0), (2,2), (2, -2), (7,3)}
Answer:
The final set is not a function.
Step-by-step explanation:
There are two x-values that are the same, making it not a function. Notice, this is not the same in the other sets, because each x corresponds to exactly one y-value in the other functions.

Solve the inequality: x - 12 < -16
Answer:
x > -4
Step-by-step explanation:
What you do is in order to get the x by itself you need to do the opposite of -12 which is just +12 so you need to add 12 to both sides. You should end up with something like this:
x -12 + 12 < -16 + 12
x < -4
So, that should be your answer. Hope this helps :) Have a good day!!

Answer:
15 bags
Step-by-step explanation:
She can fill 5 bags per each pound (because there are 5 [tex]\frac{1}{5}ths[/tex] per pound)
Since there are 3 pounds, and , again, each pound can fill 5 bags, she will need 15 bags.
Another way too look at it is to ask how many 1/5ths are in 3 pounds. To find this answer mathematically:
3 ÷ 1/5 = 15 because when we divide by a fraction, we need to flip it and then multiply (so 3 ÷ 1/5 is actually 3×5)
The functions f(x) and m(x) are graphed below. If m(x) = f(x) + k, what is the value of k

By rounding to 1 significant figure, estimate
361.42 / 79.45
Answer: 5
Step-by-step explanation:
To solve this, we would have to divide 361.42 by 79.45. This will be:
= 361.42 / 79.45
= 4.549
We can see that 4.549, has 4 significant digits. By the time we round it off to 1 significant number, we would have 5.

Raj is 3 inches taller than Howard. Let h represent Howard’s height. Write an algebraic expression to represent Raj’s height.
Answer:
h + 3
Step-by-step explanation:
Since Raj is 3 inches taller than Howard (h), Raj would be h + 3 inches taller than Raj, giving you your answer.
Answer:
h + 3
Step-by-step explanation:
h + 3
3 = they are 3 inches TALLER which means you need to add 3
h = Howards height
So all you would need to do is add Howards age by 3, and you will get Raj's height. They said that " Raj is 3 inches taller than Howard", so that means when you get Howard (h) you would need to add it by 3 (3 inches taller), and you will be able to get Raj's height.
Hope this helped!

Y=-2x+6 what is the y intercept
Answer:
the Y intercept is 6
Step-by-step explanation:
the Y intercept of a linear equation like that equation
any equation formed as: y=mx+b
B of the equation would always be the Y intercept
The y-intercept of the equation y = -2x + 6 is 6. It means that the line intersects the y-axis at the point (0, 6), where the y-coordinate is 6.
In the equation y = -2x + 6, the y-intercept represents the value of y when x is equal to zero.
To find the y-intercept, we substitute x = 0 into the equation:
y = -2(0) + 6
y = 0 + 6
y = 6
Therefore, the y-intercept of the equation y = -2x + 6 is 6. It means that the line intersects the y-axis at the point (0, 6), where the y-coordinate is 6.
