Answer:

25%.

Step-by-step explanation:

We are asked to determine the percent of a data set is represented in $Q_1$ .

We know that 1st quartile or lower quartile of a data set represents 25% of data points. Median represents 50% of data points and upper or 3rd quartile represents 75%of data points of a data set.

Therefore, 25% of a data set is represented by 1st quartile ( $Q_1$ ).

Three high school basketball teams measured the heights of all of their basketball players: The Derby Dragons have a mean height

sweet [91]

Answer:

The Ballwin Bears are taller on average, and the Aviston Aces have players whose heights are more consistent.

Step-by-step explanation:

for derby dragon;

mean height = 72 inches

standard deviation = 1.2 inches

for aviston aces:

mean height = 70.8

standard deviation = 0.7 inches

for balwin bears;

mean height = 73 inches

standard deviation = 1.0 inches

the mean height of aviston aces < mean height of derby < mean height of balwin bears

So on average the balwin bears are taller.

The standard deviation of derby dragon is > that of balwin bears > aviston aces.

So the more consistent height is that of aviston aces players.

Evaluate the expression 1 2 over 5 x plus 3 2 over 3 for x equals 1 fourth.

ch4aika [34]

The evaluated expression needed is $\frac{18}{5}$ or 3 $\frac{3}{5}$

The expression that needs to be evaluated is

1 $\frac{2}{5x}$ + 3 $\frac{2}{3}$ for x = $\frac{1}{4}$

We are being asked here to solve the mathematical equation by substituting the value of x for 1/4. If we go ahead and do the substitution we have;

1 $\frac{2}{5(0.25)}$ + 3 $\frac{2}{3}$

where x = $\frac{1}{4}$ = 0.25

this is equal to

1 $\frac{2}{1.25}$ + 3 $\frac{2}{3}$ =

1 * 8/5 + 3 * 2/3

8/5 + 2 = 18/5 = 3 $\frac{3}{5}$
