Answer:
Mean: 23. 54545455
Median: 22
Step-by-step explanation:
The median represents the center the most because when you are solving for the median, you look for the direct center of the terms which will be 22, the median.
In a quadratic function, recall that the discriminant D = b2 - 4ac. For which function is it true that a < 0 and D = 0?
Answer:
If D = 0, then the quadratic equation has 1 solution x = − b/2a
Step-by-step explanation:
If we have a quadratic equation x² +3x-4= 0
Then the corresponding values of a= 1, b=3, c= -4
Finding the discriminant gives
D= b2 - 4ac.
D= 3²- 4(1) (-4)
D= 9 + 16
D= 25
Here a> 0
But if a< 0 e.g a= -1
D= b2 - 4ac.
D= 3²- 4(-1) (-4)
D= 9 - 16
D= -7
Here a < 0 so we get the answer -7 < 0
D= b2 - 4ac.
D= 4²- 4(-1) (-4)
D= 16 - 16
D= 0
Here a< 0 and b= - c so that D= 0
When D < 0 roots do not exist.
If D = 0, then the quadratic equation has 1 solution x = − b/2a
This can be found out by using the quadratic formula
x= -b±√b²- 4ac/ 2a
But D= 0
x= -b±0/ 2a
x= -b/2a

Last year, Nicholas started babysitting to earn extra spending money. Over the summer, he
tracked how much money he earned at each babysitting job. This box plot shows the results.
Babysitting earnings ($)
What percent of the time did Nicholas earn $25 or less?
Answer:
25%
Step-by-step explanation:
From the boxplot Given, an earning of $25 or less is represented on the boxplot as the lower quartile of the distribution which is the point at the start of the box. The lower quartile value is the percentage value up to 25% that is the first 25% of the distribution.
Hence, the percentage required = 25%
Hence, Nicholas earned $25 or less about 25% of the time.

24 – (-14) = ______
-9 · -5 = ______
31 + x = 15 x = ______
2 x + 5 = 15 x = ______
Step-by-step explanation: (Answers in bold )
24-(-14) using the keep change change rule you get 24 +14 = 38
-9*-5 =45 (negative times a negative = a positive )
31+x=15x subtract x from both sides
31=14x divide by 14
31/16 ---or---> 2.21
2x+5= 15x subtract 2x from both sides

radio tower. Spongebob is 80 meters away from the tower. He looks up at
King Kong with an angle of elevation of 23º. Find King Kong's height to the
nearest tenth of a meter.
Answer:
127.1 m
Step-by-step explanation:
We are given the value of the adjacent side and we are to find the value of the opposite side
Tan would be used to determine this value
Tan 23 = opposite / adjacent
1.5882 = x / 80
x = 80 x 1.5882
x = 127.056 m
x = 127.1m
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

What is the perimeter of the rectangle?
Answer:
10 feet
Step-by-step explanation:
Perimeter of rectangle = 2l+2b
Area of the rectangle = l x b
Area of the rectangle = 4 square feet
possible factors of 4 = 2x2/4x1
So sides of the rectangle are 4 & 1 as 2&2 would make it a square
So perimeter= 2x4+2x1
= 8+2
= 10 feet

Which shows the expression (4a ^ 5 * b) ^ 3 simplified?
A rectangle has a perimeter of 72 millimeters and a width of 8 millimeters. What is the length of this rectangle?
Answer:
28
Step-by-step explanation:
Since the perimeter is the width + width + length + length, we know that there 2 of the 8 millimeter width in the perimeter. So multiply 8 by 2, which is 16. So 16 of the 72 represents both widths. So subtract 16 from 72. You're left with 56, which represents 2 of the length. So divide 56 by 2, and you get one of the length, which is 28.
Answer:
28 ^^

Consider the probability statements regarding events A and B shown below P(A or B) = 0.96 P(A and B) = 0.16 P( A | B ) = 0.32 Determine P(A) and P(B).
Answer:
P(A) = 0.62
P(B) = 0.5
Step-by-step explanation:
Given the following
P(A or B) = 0.96
P(A and B) = 0.16
P( A | B ) = 0.32
According to conditional probability
P( A | B ) = P(A and B) /P(B)
0.32 = 0.16/P(B)
P(B)= 0.16/0.32
P(B)= 0.5
P(A or B) = p(A) + p(B) – p(A and B)
Substitute the given values
0.96 = P(A)+ 0.5 - 0.16
P(A) = 0.96 - 0.5 + 0.16
P(A) = 0.62
The value of [tex]P(A)\\[/tex] is [tex]0.62[/tex] and the value of [tex]P(B)[/tex] is [tex]0.5[/tex] .
The possibility of a random event to occur is called probability. It lies between the range of [tex]1[/tex] and [tex]0[/tex].
Given data:
[tex]P(A or B) = 0.96[/tex]
[tex]P(A and B) = 0.16[/tex]
[tex]P( A | B ) = 0.32[/tex]
According to the conditional probability definition,
The occurrence of an event or event that occurs as a result of previous events or events is called conditional probability.
[tex]P( A | B ) = \dfrac{P(A and B)} {P(B)}[/tex]
[tex]0.32 = \dfrac{0.16}{P(B)}[/tex]
[tex]P(B)= \dfrac{0.16}{0.32}[/tex]
[tex]P(B)= 0.5[/tex]
[tex]P(A or B) = p(A) + p(B) - p(A\ and \ B)[/tex]
Substitute the given values in the given relation,
[tex]0.96 = P(A)+ 0.5 - 0.16[/tex]
[tex]P(A) = 0.96 - 0.5 + 0.16[/tex]
[tex]P(A) = 0.62[/tex]
Thus, the value of [tex]P(A) = 0.62[/tex] and the value of [tex]P(B)[/tex] is [tex]0.5[/tex].
