Answer:

Median = 10

Mean = 18

Step-by-step explanation:

1) Median equals the middle number of a set.

To find median, place the numbers from least to greatest. So that’ll turn to be:

0, 8, 9, 10, 26, 35, 38

The middle number is 10.

2) Mean is the average of all the numbers.

To find mean, add all the numbers together. So 0+8+9+10+26+35+38 = 126

Then, divide the sum by the amount of numbers you added. We added a total of 7 numbers to get 126. 126/7 = 18. The average is 18.

Which of the following equations is on the same path as x=2-3t, y=7-6t?

Svet_ta [14]

Answer:

C. $y = 3+2\cdot x$

Step-by-step explanation:

Let be the parametric equations $x = 2-3\cdot t$ and $y = 7 - 6\cdot t$ , we need to clear $t$ and eliminate it afterwards to obtain a function of the form $y = f(x)$ :

$x = 2 - 3\cdot t$

$3\cdot t = 2 - x$

$t = \frac{2}{3}-\frac{1}{3}\cdot x$ (1)

$y = 7 - 6\cdot t$

$6\cdot t = 7 - y$

$t = \frac{7}{6} - \frac{1}{6}\cdot y$ (2)

By (1) and (2):

$\frac{2}{3}-\frac{1}{3}\cdot x = \frac{7}{6}-\frac{1}{6}\cdot y$

$4 -2\cdot x = 7 - y$

$y = 3+2\cdot x$

Hence, the correct answer is C.

The data set shows the numbers of hours that employees at a certain shop worked in one week. What is the mean number of hours th

lyudmila [28]

Answer:

33.6

Step-by-step explanation:

The following data set shows the numbers of hours that employees at a certain shop worked in one week

34 36 32 40 39 17 35 33 36 34

The mean is the average of the numbers. It is easy to calculate - add up all the numbers, then divide by how many numbers there are.

Hence,

$\text{mean}=\dfrac{34+36+32+40+39+17+35+33+36+34}{10}=\dfrac{336}{10}=33.6$

8. Which of these is not an integer 6 6 A 3 C E 3

Mnenie [13.5K]

An integer is a whole number.

The answer isn't A, because 6/3=2 and 2 is a whole number.

The answer isn't C, because 6/2=3, and 3 is a whole number.

The answer therefore has to be B, because 3/6=1/2 and 1/2 isn't a whole number or an integer.

Solve. 7x − 2 = −23 x =

Zielflug [23.3K]

7x-2=-23 add 2 to both sides to get 7x by itself
7x=-23+2 now add the right side
7x=-21 now divide both sides by 7
x=-21/7
x=-3
