Median =  middle number

Total ten numbers so 
median =   (17 + b)/2
given median = 18
so
(17 + b)/  2 = 18
17+b = 36
b = 36 - 17
b = 19

Now you have the data set
7, a , 12, 15 , 17, 19, 20, 22, 24 , 25

Mean =  (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24  +25)/ 10
Given mean = 17

so
17 = (7 + a + 12+ 15 +17 + 19 + 20 + 22 +24  +25)/ 10
17 = (a + 161) / 10
a + 161 = 170
a = 170 - 161
a = 9

answer
a = 9
b = 19

VARVARA [1.3K]

Question not well presented and diagram is missing

Quadrilateral WILD is inscribed in circle O.

WI is a diameter of circle O.

What is the measure of angle D?

See attached for diagram

Answer:

Step-by-step explanation:

Summation of opposite angles of a quadrilateral inscribed in a circle is 180°, given that the vertices are on the circle.

Given

<WIL = 45°

<ILD = 109°

In the attached;

<WIL + <WDL = 180° (Opposite angle of quadrilateral)

Substitute 45° for <WIL in the above expression

45° + <WDL = 180° ---- Collect like terms

<WDL = 180° - 45°

<WDL = 135°

Hence, the measure of angle D is 135° (See attached)

VikaD [51]
Whenever we multiply values where the bases are the same, you add the exponents.

2+4=6, so the answer is

5^6

Hope this helped :)

A soccer team uses 5-gallon coolers to hold water during games and practices. Each cooler holds 640 fluid ounces. The team has s
polet [3.4K]
<h3>Answer:   640c - 6.25s - 8.75g</h3>

===============================================

Work Shown:

s = number of small cups

g = number of large cups

c = number of coolers

----------

1 cooler = 640 fluid ounces

c coolers = 640c fluid ounces

1 small cup = 6.25 fluid ounces

s small cups = 6.25s fluid ounces

1 large cup = 8.75 fluid ounces

g large cups = 8.75g fluid ounces

----------

T = total amount of water poured

T = (amount from small cups) + (amount from large cups)

T = 6.25s+8.75g

L = amount of water left

L = (original total amount of water) - (amount of water poured out)

L = 640c - T

L = 640c - (6.25s+8.75g)

L = 640c - 6.25s - 8.75g
