Bill needs to earn $28 on Sunday so that the average is $22 each day, the correct option is C.
What is a Graph?
The graph is a mathematical representation of the relation between two objects.
Bill works as a waiter and he keeps track of the tips that he earns daily.
The tip earned on Monday is $14
The tip earned on Tuesday is $12.
The tip earned on Wednesday is $13.
The tip earned on Thursday is $25
The tip earned on Friday is $32
The tip earned on Saturday is $30
Average is the mean of the data set obtained by summing all the values of the data set and then dividing it by the number of data in the set.
The average money that he wants to make by tip is $22
Let the tip earned on Sunday is $x.
Then by the formula of average
22 = ( 14+ 12 + 13+ 25+ 32 + 30 +x ) / 7
Multiplying 22 by 7
154 = 14 + 12 + 13 + 25+ 32 + 30 +x
154 = 126 + x
x = $28

Since it is a right angled triangle, Pythagorean theorem will be applied to it.
So, we use the formula -
hypotenuse^2 = side1^2 + side2^2
Here, hypotenuse (ladder) = 5 feet, side1 (wall) = 4 feet, side2 (base of the wall) = unknown.
So, we have, 5^2 = 4 ^2 + side2^2
==> side2^2 = 5^2 - 4^2
==> side2^2 = 25 - 16
==> side2^2 = 9
==> side2 = square root (9)
==> side2 = 3
So, the final answer is --> the bottom of the ladder is 3 foot away from the base of the wall.
By Pythagoras theorem,
H² = B² + L²
where L is the altitude (wall), B is the base (ground) and H is the hypotenuse (ladder).
⇒ 5² = B² + 4²
⇒ 25 = B² + 16
⇒ B² = 25 - 16 = 9
⇒ B = 3
The bottom of the ladder must be 3 feet away from the base of the wall.

If 15% correspond to 100%
then 18% correspond to X%
We notice that both lines are in the following proportion:
(15) / (100%) = (18) / (X%)======> X%= (18 x 100%) / 15= 6/5 = 1.2 =120%
Answer:
Maxine is incorrect.
Step-by-step explanation:
18 - 15 = 3 3/15 = 0.2 0.2(100) = 20.
20% is the percent of increase. 120% would be the total of both combined. Since we are only looking for how much more, it would be 20%.

What is the arithmetic operator?
Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
As per the given,
Time is taken to Lisa to cover 200 m in normal = one and a 10 seconds.
Since 1 minute = 60 seconds.
One and 10 seconds = 60 + 10 = 70 seconds.
Time is taken in low hurdles = one and a half minutes.
⇒ 60 + 60/2 = 90 seonds.
Thus, 90 seconds - 70 seconds = 20 seconds.
Hence "Lisa Lilly takes 20 seconds more due to low hurdles".
