Answer:
It is a right triangle.
So, using Pythagorean theorem: OS² = OR² - RS²
OR = r (radius) + 8
OS = r
RS = 16
=> r² = (r+8)² - 16²
r² = r² + 16r + 64 - 256
r² = r² + 16r - 192
16r = 192
r = 192 / 16 = 12cm²
a) 12 cm²
b) 12 + 8 = 20 cm²
The lowest number in the data set is -5.
<h3>How to illustrate the information?</h3>
Let the data sets be consecutive numbers that has a highest number of 2.
Consecutive numbers mean that the.numvers follow each other. This will be:
-5, -6, -7, -8, -9, 0, 1, 2
Based on the numbers illustrated above, the lowest number is -5.

So for each of the graphs, you basically just have to fill out slope form, which is y=my+b. And to make this equation, you need to find each variable.
First, find the slope. To calculate slope, count the rise (how many units up or down) the line goes from any point to the next immediate point, then the run (how many units left or right.) This should leave you with a fraction, rise/run. For example, on number 3, from labeled points (-5, -4) to (5,2) (double check cause it’s hard to see on my phone, but i think those are the points on 1??) it rises 6 units (-4 to 2) and runs 10 units (-5 to 5). This gives you your rise/run fraction, which is 6/10, simplified to 3/5.
So the slope fills out the m part of the equation. For 3, we found that slope is 3/5, and that fits into the m variable of the slope equation.
This makes it y=3/5x+b.
The last (and considerably less confusing) step is to find b. b is the y-intercept, which is just the point in the graph where the line crosses the y-axis and x=0. On 3, this would be (0,-1) or just -1.
So fill -1 into the b slot of the equation, and you get y=3/5x-1. And thats it!!
Let me know if you still need help on any of the other problems, but I hoped this helped to clear it up!! :)
<span>Since there is no files attached to see the shape of the distribution, let us just have it this way:
The statement, "Because the two distributions displayed below have similar shapes, they have the same standard deviation." is false. This is false because distributions having the same mean and standard deviation can have very different shape of distribution. </span>
she can read a total of 0.83 pages a minute if she reads at the pace she was reading at because if you take the amount of pages she read (7.5) and you divide by the amout of minutes read (9) then you can see if she read at a constant rate she would read 0.83 pages a minute
