Hi there!
The answer is 3.8
The slope of a line is a number that indicates the steepness and the direction of a line. A line with a negative slope is a decreasing line, and a line with a positive slope is increasing.
The slope of a line is the number that is positioned just before the variable in the equation, which is mostly the x. In this situation, the number that is positioned in front of the x, is 3.8. Therefore, the slope of the line is 3.8. This also indicates that the function is steep and increasing.
~ Hope this helps you!

Yes thank you
Step-by-step explanation:
Answer: 4
Step-by-step explanation:
For given Population standard deviation , the formula to sample size is given by :-
, where z* = Two-tailed critical value.
E = Margin of error.
Given : years
We know that , Critical value for 90% confidence interval : z* = 1.645
Margin of error : E=1.3 years
Then, the minimum sample size required to construct a 90% confidence interval for the population mean will be :-
[Rounded to the nearest whole number.]
Hence, the minimum sample size required = 4
The rule for the reflection
rx-axis (x, y) → (x, –y)
ry-axis (x, y) → (–x, y)
<h3>Further explanation</h3>
A reflection is an example of a transformation
Reflection is the process of mirroring each point on the geometry of a certain line.
The original figure is called the pre-image and the final figure is called the image
The image will be congruent with the pre image and the distance of the image to the mirror axis is the same as the distance of the pre image to the mirror axis
There are several reflection equations:
- The equation of reflection across the<em><u> x-axis
</u></em>
x '= x
y '= - y
can be written
- The equation of reflection across the <u><em>y-axis
</em></u>
x '= x
y '= -y
can be written
- The reflection equation across the line <u><em>y = -x
</em></u>
x '= - y
y '= - x
can be written
- The reflection equation across the line x = h
x '= 2h-x
y '= y
can be written
- The reflection equation across the line y = k
x '= x
y '= 2k-y
can be written
So the correct rule for reflection is:
rx-axis (x, y) → (x, –y)
ry-axis (x, y) → (–x, y)

Answer:
alright- i can help you with the 7.12----
Step-by-step explanation:
1.) a. 11 12 13 14 15 16 22 23 24 25 26 33 34 35 36 44 45 46 55 56 66
b. 6/10
c. It’s less than 34 because there’s 6 numbers. 6 divided by 100= 16
2--- i'm going to send you a link on the other question
3.) a. 1/6
There are 6 possibilities. We are looking for one out of 6 of those
possibilities, so we get the fraction: 1/6.
b. I don’t understand this one
c. The probability that you don’t roll a six is 5/6. There are 6 possibilities,
but we are looking where it is not one possibility. There are 5, so the
answer is 5/6
