3 9/10 * -8 / 3 = 39 / 10 * -8 / 3 = -52 / 5
Answer:
78 and 99
Step-by-step explanation:
let x be the first quiz grade and y be the second quiz grade. we can set up this formula:
x+21 = y
and this formula:
2x-57 = y
therefore, x+21 = 2x-57
add 57 to both sides: x+78 = 2x
subtract x from both sides: 78 = 2x-x
simplify: 78 = x
now we know the first quiz grade is 78. we can plug this into the first formula:
78+21 = y
add to get y = 99
The first steps would be to put the numbers in order:
7, 7, 8, 9, 9, 10, 10, 11, 12, 13, 14, 14, 27
Now you can see the outlier(s) which would be 27.
Now that you know your one outlier that eliminates two of the answers so your options are either A or C.
Since the outlier is a bigger number, the answer is:
C. <span>
There is one outlier that indicates an unusually large number of cars were in the parking lot that day.</span>

Answer:
The area of the deck that surrounds the hot tub is 17.9 m².
Step-by-step explanation:
Base of deck = 5 m
Height of deck = 5 m
Area of deck = base*height
= 5*5
= 25 m²
A circular hot tub is placed in the deck whose diameter is 3 m.
Radius = diameter/2
= 1.5 m
Area of the circular hot tub = πr²
= 3.14*(1.5*1.5)
= 7.07 m²
Area of the deck that surrounds the hot tub = Area of deck - Area of tub
= 25 - 7.07
= 17.93 m²
= 17.9 m²
