Answer:
The value of x=7 and y=3 make the equation true.
D is correct.
Step-by-step explanation:
If the point (7, 3) is on the graph of an equation.
If point lie on any graph then the value of x and y satisfy the equation. It means equation would be true for the given passing point.
First value of point is x and second value is y
For given point: (7,3)
x=7 and y=3
If we put x=7 and y=3 in the graph of the equation then equation must be true.
because it makes equation true.
For true equation left side must be equal to right side.
Hence, The value of x=7 and y=3 make the equation true.
Answer:
Standard deviation(S.D) = √{Mean difference(D²) - Mean(M)}
S.D.= 16.6
Step-by-step explanation: A) M =33.2
∴ S.D = √D² - 33.2
16.66 = √D² - 33.2
D² = 16.66² + 33.2 = 277.56 - 33.2 = 244.36
∴D = √244.36 = 15.6
B) M= 49.9
∴ S.D.=√D² + 49.9
16.6 =√D² + 49.9
D² = 16.6² + 49.9 = 277.56 + 49.9 = 327.46
∴ D = √327.46 = 18.1
C) M = 102.8
∴ S.D. =√D² + 102.8
16.66 =√D² + 102.8
D² = 16.66² + 102.8 = 277.56 + 102.8 = 380.36
∴ D =√380.36 = 19.5
D) M = 154.2
∴ S.D. = √D² + 154.2
16.66 =√D² + 154.2
D² = 16.66² + 154.2 =277.56 + 154.2 = 431.76
D =√431.76 = 20.8
To find the number, we need to work backwards from the given quotient of 20. Double the number, subtract 6, and divide the result by 2 to get the number.
To find the number, we need to work backwards from the given quotient of 20. Let's call the number x.
Step 1: Double the number: 2x
Step 2: Subtract 6 from the result: 2x - 6
Step 3: Divide the answer by 2: (2x - 6) ÷ 2
Since the quotient is 20, we can set up an equation: (2x - 6) ÷ 2 = 20
Multiply both sides of the equation by 2: 2x - 6 = 40
Add 6 to both sides of the equation: 2x = 46
Divide both sides of the equation by 2: x = 23
Therefore, the number is 23.

Answer:
A is the correct answer
Step-by-step explanation:
i took the test
A ; the total number of people at the club meeting
B; 2c-10
what is the answer
A; a is high
B; b is high
C ; Aand B are equal
D : no answer
The total number of people at the club meeting is 2c -10 (option B). Further, the correct answer for comparison is that 'A and B are equal' (option C).
In this question, we are told that the number of club members is c and there are 10 more club members than nonmembers. This means that there are c - 10 non-members. Therefore, the total number of people at the club meeting is the sum of the number of members and non-members which is c + (c - 10) = 2c -10. Therefore, the correct answer to the question, 'what is the total number of people at the club meeting?' is: B; 2c-10.
When it comes to choosing between options A, B, C, and D to determine if A (the answer to part A) is higher, B (the answer to part B) is higher, both are equal or there is no answer, we see that since A is actually equal to B, the correct answer is: C, A and B are equal.

Regular pay: $12/hour
Time and a half: $12/hour * 1.5 = $18/hour
40 hours * $12/hour + 2 hours * $18/hour = $480 + $36 = $516
Answer: $516
