Answer:
the mean is 7.2 and the median is 8
Step-by-step explanation:
when you add up all the data you will get 36 which you divide by 5 since there are 5 different values.This will result to 7.2 as your final answer .Whereas for the median out of the 5 numbers the median would be the 3rd number which when you order them from smallest to largest it would be 8.

What two numbers multiply to -18, adds up to 3
Answer:
6 and -3
Step-by-step explanation:
6 times -3 equals -18 because a positive times a negative equals a negative. 6 plus -3 equals 3, remember that a positive plus a negative can be rewritten as subtraction. So 6+(-3)=6-3, which equals 3.
Paul Curcio earns $7.45 per hour for regular time up to 40 hours, time-and-a-half for overtime, and double time for working on holidays. Find his gross pay (in $) if he worked 6 holiday hours for a total of 58 hours Monday through Saturday.
Answer: $521.50
Step-by-step explanation:
58 hours worked
40 hours regular x $7.45 = $298
6 hours holiday x $7.45 x 2 = $89.40
58 - 46 = 12 hours overtime x $7.45 x 1.5 = $134.10
$298 + $89.40 + $134.10 = $521.50

i got this question right
Step-by-step explanation:
Let A={2,3,4} B={2,5,6} C={5,6,2} and D={6}. Determine if the following statements are true:
i). 4€C
ii). 5€C
iii). A=B
iv). B=C
Answer:
i. 4∈C => False
ii. 5∈C => True
iii. A = B => False
iv. B=C => True
Step-by-step explanation:
Given sets are:
[tex]A = \{2,3,4\}\\B = \{2,5,6\}\\C = \{5,6,2\}\\D = \{6\}[/tex]
Lets look at the statements one by one.
i. 4∈C
This statement means that 4 is a member of set C. Looking at the members of set C, it can be concluded that the statement is wrong as C doesn't contain 4.
ii. 5∈C
This statement is true as 5 is a member of C.
iii. A=B
This statement states that set A is equal to set B. Two sets are said to be equal if there number of elements and members are same. Set A and Set B have different members so this statement is false.
iv. B=C
Set B and Set C have equal number of members and the members (5,6,2) are also same so the statement is true.
Hence,
i. 4∈C => False
ii. 5∈C => True
iii. A = B => False
iv. B=C => True

Given:
Sam's Swimming Pool Cleaning has an annual net income of $46,900.
Sam charges $25 per week for each of his customers for 52 weeks.
His annual operating expenses, including labor and supplies, are $48,000.
His total income,
= 46900 + 48000
= 94900.
The number of customers = 94900/(25 x 52) = 73.
Therefore, the number of customers is 73.

Shelley got 22 questions correct on her math test. She got an 88%. How many questions were on Shelley’s math test?
Answer:
Step-by-step explanation:
Let the total question on Shelley's math test be x
If 22 questions is equivalent to 88% of the total score, then
88% of x = 22
88/100 x= 22
88x/100 = 22
cross multiply
88x = 22*100
88x = 2200
x = 2200/88
x = 25
Hence 25 questions were on her math test.

There were 935 offenses in 2000 and 2448 offenses in 2019. What is the percentage increase?
Answer:
Approximately 262%
Step-by-step explanation:
To find the percentage increase divide the new amount of offenses by the old amount of offenses:
2448/935 = 2.618
2.618 rounds to 2.62. Convert 2.62 into a percentage: 262%
The percentage increase between the amount of offenses in 2000 and the amount of offenses in 2019 is approximately 262%.

Two people climbed to the roof of a building. The old person walked up a gentle ramp. The young person climbed up a steep spiral staircase. Which person did more work? Explain.
Answer:
both people actually did the same work
Step-by-step explanation:
Work = Force × Distance
The person that climbed the steep spiral staircase used more force but covered a shorter distance. On the other hand, the person that walked up a gentle ramp used less force but covered a longer distance. Since both people reached the same height, the force against gravity was the same.
Based on the information given, the person that will do more work is the young person.
From the information given, it was stated that two people climbed to the roof of a building. The old person walked up a gentle ramp while the young person climbed up a steep spiral staircase.
In this case, since the young person climbed up a steep spiral staircase, the young person will do more work.

Answer:
2x + 5y = -4
Step-by-step explanation:
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
========================================================
Explanation:
Let's use point slope form to get
y - y1 = m(x - x1)
y - y1 = -4(x - x1) .... plug in the given slope m = -4
y - 5 = -4(x - 2) .... plug in the given point (x1,y1) = (2,5)
Now we isolate y
y - 5 = -4(x - 2)
y - 5 = -4x + 8
y = -4x + 8 + 5
y = -4x + 13
This equation is in slope intercept form y = mx+b
m = -4 is the slope
b = 13 is the y intercept
To get this into standard form, we add 4x to both sides so that the x and y terms are on the left side
y = -4x+13
y+4x = 13
4x + y = 13 is the final answer
This is in standard form Ax+By = C where
A = 4
B = 1
C = 13
--------------------------
Let's check the answer. Plug in (x,y) = (2,5) to find that...
4x+y = 13
4*2 + 5 = 13
8 + 5 = 13
13 = 13
We get the same thing on both sides, so the last equation is true. This means the first equation is true when (x,y) = (2,5). This confirms the point (2,5) is on the line and helps confirm the answer.

The Juniors and Seniors reported their scores on a standardized math test. The teacher displayed their scores on dot plots.
What is the MAD for the Junior and Senior scores?
0.7
29.3
14.3 and 15
14 and 14.4
Answer:
14 and 14.4
Step-by-step explanation:
✍️MAD for Juniors:
✔️Write out the individual scores represented in the dot plot:
505, 505, 510, 515, 525, 530, 530, 540, 550, 550
✔️Find the mean of the data set = [tex] \frac{505 + 505 + 510 + 515 + 525 + 530 + 530 + 540 + 550 + 550}{10} = \frac{5,260}{10} = 526 [/tex]
✔️Find |data value - mean|:
|505 - 526| = 21
|505 - 526| = 21
|510 - 526| = 16
|515 - 526| = 11
|525 - 526| = 1
|530 - 526| = 4
|530 - 526| = 4
|540 - 526| = 14
|550 - 526| = 24
|550 - 526| = 24
✔️Find the sum of |data value - mean| and divide by 10:
[tex] \frac{21 + 21 + 16 + 11 + 1 + 4 + 4 + 14 + 24 + 24}{10} = \frac{140}{10} = 14 [/tex]
✅M.A.D = 14
The same steps would be taken to find the MAD for Seniors.
✍️MAD for Seniors:
✔️Write out the individual scores represented in the dot plot:
535, 535, 535, 550, 550, 550, 560, 575, 575, 580
✔️Find the mean of the data set = sum of all values in the data set ÷ 10 = 554.5
✔️Find the M.A.D by dividing the sum of |data value - mean| by 10:
[tex] \frac{144}{10} = 14.4 [/tex]
✅M.A.D = 14.4
