Answer:
Mean weight = 19 pounds
Step-by-step explanation:
From the question given above, the following data were obtained:
17, 11, 21, 24, 22
Number of data (n) = 5
Mean weight =?
The mean of a set of data is the value obtained by adding all the data together and dividing the result obtained by the total number of data. Thus, the mean can be obtained as follow:
Summation of data = 17+ 11 + 21 + 24 + 22
= 95
Number of data = 5
Mean = Summation of data / Number of data
Mean = 95 / 5
Mean weight = 19 pounds
Therefore, the mean weight of the data is 19 pounds
Step-by-step explanation:
multiply it
x²-3x+3x-9=0
x²-9=0
x²=9
square root both side we get
x=3
If you move the negative on the left side of the second equation over to the right side, then we can see that the equation is equivalent to

.
Remember that an equation

represents a line with slope

and y-intercept

. Since both equations given have a slope of -2, but have different y-intercepts, they are
parallel.
Answer:
The table will be:
x |-2 | -1 | 0 | 1 | 2
y | 1 | 4 | 5 | 4 | 2
Step-by-step explanation:
The function is:

a) The x values of the table is:
x |-2 | -1 | 0 | 1 | 2
So, when x = -2, y will be:

Doing the same with the other x values we have:




The table will be:
x |-2 | -1 | 0 | 1 | 2
y | 1 | 4 | 5 | 4 | 1
I hope it helps you!
the second slide is A. 22
and the last one is x=81 z=99 and y=68
hope this helps
