Answer:
3.5
Step-by-step explanation:
300÷85=3.529
so it would take him approximately 3.5 more days before he finishes the book
Answer: for first one x=28-5y
second one x=-3/29(y-7)
Step-by-step explanation:
im sure its right
Using the normal distribution, it is found that the replacement time that separates the top 18% from the bottom 82% is of 11.23 years.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
In this problem, the mean and the standard deviation are, respectively, given by
.
The desired value is the 82nd percentile, which is X when Z = 0.915, hence:


X - 9.4 = 0.915(2)
X = 11.23
The replacement time that separates the top 18% from the bottom 82% is of 11.23 years.

Slope is the rise/run of the line. With the rise being how far apart the two points are on the y axis, and the run being how far apart the two points are on the x axis.
In this case, the first point is 6 units down from the other and 4 units over from it. (6/4) then from there you would simplify your fraction. (Both numerator and denominator can be divided by 2).
Your slope in total is 3/2. Hope this helped.
Answer:
The forumula for finding area of the circle is \pi r^2.
Step-by-step explanation:
Let's find the radius of the mug:
r=\frac{d}{2}=\frac{8}{2}=4
Now, we can to express the area of each cookie in terms of pi:
Area= \pi *4^2=16\pi
