The school athletic director had a budget of $703.55 to purchase 55 items for the volleyball team. he purchased uniforms for $18.50 each, volleyball balls for $11.99 each and knee pads for $9.75 per pair. He purchased six more balls than uniforms. Define the variables and write a system of equations to represent the situation. i know the equations are:
U+V+K=55
18.5U+11.99V+9.75K=703.55
U+6=V or U-V=-6
im just not sure as to how to solve it.
U= uniforms
V= volleyballs
K= kneepads

U= uniforms

V= volleyballs

K= kneepads

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.  

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
