Abby buys 1 sheet of stickers. 5 strips of ten and 9 singles. How many stickers did she buy?

We can solve this by writing down all of the variables we know. We will call the distance traveled on Saturday, x. The distance traveled on Sunday will be y.

x = distance traveled saturday
y = distance traveled sunday

We are told that on sunday he rode 3 miles more than 2/3 the distance on saturday. We can write a new formula.

y = (2/3)x + 3

We also not the total distance travelled, x + y = 43, now we solve for x.

x + y = 43
x + (2/3)x + 3 = 43
5/3x = 40
x = 24 miles

y = (2/3)(24)+3
y = 19 miles

Therefore, Mario biked 24 miles on Saturday and 19 miles on Sunday which gives us the total of 43 miles for the whole weekend.

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

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 $Q_3-Q_2=Q_2-Q_1$
