A)2.8
b1) 4.5/2.8
b2)impossible because if you want to do trigonometry you can't have that is an angle (Which is 148.1) larger than 90 degrees.
but if its angle BAF then the angle would be 2.8/5.3
c)41.32

The data represent the age of world leaders on their day of inauguration. Find the five-number summary, and construct a boxplot

Mumz [18]

Answer:

Minimum value = 43, $Q_1=52$ , $Q_2=Median=61$ , $Q_3=67$ , Maximum value = 69.

Distribution is negative skewed.

Step-by-step explanation:

The given data set is

44, 43, 67, 68, 57, 65, 52, 62, 69, 54, 53, 61, 67, 48, 65

Arrange the data in ascending order

43, 44, 48, 52, 53, 54, 57, 61, 62, 65, 65, 67, 67, 68, 69

Divide the data in 4 equal parts.

(43, 44, 48), 52, (53, 54, 57), 61, (62, 65, 65), 67, (67, 68, 69)

Minimum value = 43

$Q_1=52$

$Q_2=Median=61$

$Q_3=67$

Maximum value = 69

Starting and end point of box plot represent the minimum and maximum value respectively. Box starts from the first quartile to the third quartile. A vertical line goes through the box at the median.

The shape of the distribution.

Normally distributed: If $Q_3-Q_2=Q_2-Q_1$

Positive skew: If $Q_3-Q_2>Q_2-Q_1$

Negative skew: If $Q_3-Q_2$

For the given data set

$Q_3-Q_2=67-61=6$

$Q_2-Q_1=61-52=9$

Since $Q_3-Q_2$ , therefore the given distribution is negative skewed.

I'm having one of those days where my motivation is completely gone. I know what I need to get done and how to get it done, but

Vinvika [58]

Answer:

Ah, I have this problem. I'm not sure if this would help you but I typically put on some of my favorite music which tends to get me pretty hyped up. By then I'm not so reluctant to do my school work. You can also think of something that your excited to do later which might encourage you to get your school work done so you can do that activity. Hope this helps, have a good day!
