Answer:

Step-by-step explanation:
We have been given an equation
. We are asked to solve our given equation.
First of all, we will add 3 to both sides of our equation.


Now, we will divide both sides of our equation by 4.


Upon rounding our answer to nearest thousandth (3 places after decimal) we will get,

Therefore, the solution for our given equation is
.
Answer: <span>y - 37.5 = 2.5 ( x - 7)
Explanation:
1) The point-slope form is has this form:
y - y1 = m (x - x1)
Where m is the slope or rate of change and x1, y1 are the coordinates of the point.
2) you are told that the the rate of change of water (m) is 2.5
m = 2.5
3) The point is given by that after 7 min the rain barrel contains 37.5 gallons. This is:
x1 = 7
y1 = 37.5
</span>4) Replace those value in the point-slope model:
y - 37.5 = 2.5 ( x - 7)
That is the point-slope model or equation.
Answer:
The correct option is 1.148 < σ < 6.015
Explanation:
The 99% confidence interval for the standard deviation is given below:

Where:


Therefore, the 99% confidence interval is:


Therefore, the option 1.148 < σ < 6.015 is correct
Answer:
8h + g
Step-by-step explanation
When you say "4h2", do you mean 4h multiplied by 2?
If so, then 4h2 = 8h, and 8h+g would be your answer.
Hope this helps :)
