Step-by-step explanation:
Argument
If you multiply 0.2 by 4, you get 0.8
If you multiply 0.8 by 4, you get 3.2
If you multply 3.2 by 4,, you get 12.8
Answer: 12.8
The function y=12x when plotted using the interval of
x-values from -1 to 3 will give a straight line on a given plot. Therefore the
function rule of a line y=mx+b can be used to describe the growth or
progression of this function. The rule states that y is directly proportional
to x.
Answer:
We have to find the 90% confidence interval for the mean
Given sample size
Sample mean
Population standard deviation
Here the confidence level is 90% then
And
The 90% confidence interval is
Here is the critical value at 0.05
From the tables
Now the 90% confidence interval is =
=
=(3840.44, 4133.56)
Hence the 90% confidence interval for the mean is (3840.44, 4133.56)
Answer:
90m + 5
Step-by-step explanation:
Distribute 13 to (9-6m) and distribute 14 to (12m -8)
13*9 - 13*6m + 14*12m - 14*8 =
117 - 78m + 168m - 112 =
put like terms together
117-112 -78m + 168m =
5 + 90m

On a number line,
negative means go left
positive means go right
-4 means go 4 units left of zero
-6 means another 6 units left of 0
4+6=10
that means 10 total units left or -10
