<h3>The 2
answers are: A and D</h3>
==========================================
Explanations
A. True. This is because there are 13 dots shown. You cannot use the box plot to determine this.
B. False. This contradicts choice A above. Also, we cannot use the box plot to determine how many people there are. What 12-7 = 5 is showing is that the range is 5. This means the range for the age of runners is 5 years. In other words, 5 years is the span from the youngest (age 7) to the oldest (age 12).
C. False. The median is 10 as its shown in the box plot. Recall the median for any box and whisker plot is the vertical line inside the box.
D. True. The vertical line inside the box is the median. This vertical line does not have to be exactly halfway between the left and right edges of the box.
E. False. A box plot can be used to determine variability (in terms of range and IQR). You can determine the variability from a dot plot, though you'll have to do a bit of work to get it.
F. False. Refer to choice E.
Answer:
-18
Step-by-step explanation:
5(-3)+3-6
-15+3-6
-12-6
-18
So,
h(x)=44 when x=2, so 22x2=44, so h must be 44
so if h(x) when x=15 means 44x15 which equals 660? plz help
B.22
Answer:
45 degrees
Step-by-step explanation:
The formula to find the sum of all the interior angles in an "n-gon" (n is a variable that stands for the numbers of sides, ex) 20-gon --> 20 sided polygon) is .
Let's plug in 100 to find the sum of all the interior angles in a 100-gon.
I would rather distribute than simplify the parentheses and have to multiply 180 by 98.
So:
= degrees
[REMEMBER, IT WAS NOT GIVEN THAT THIS POLYGON IS REGULAR, SO <u>DO NOT</u> DIVIDE 17640 BY 100]
Now to find the last angle, we can just subtract since we are given the value of 99 of the 100 angles (17595 degrees).
So the last angle is degrees
I agree with you, and since you got the right answer, you would know why.
1700/2890 ≈ 0.5882 = 58.82%
However, usually, you should write about 58.82% as it isn't exactly 58.82
