add the numbers in the set and divide by the quantity of numbers:
9 + 15 + 22 + 45 + 50 +60 + 65 = 266
266 / 7 = 38
the mean = 38
the absolute deviation is subtracting the number from the mean: ( all numbers are positive)
38 - 9 = 29
38 - 15 = 23
38-22 = 16
45-38 = 7
50 -38 = 12
60-38 = 22
65-38 = 27

778*12
Answer is=9336
-Charlie
Final answer:
To multiply 12 by 778, one needs to perform the standard multiplication process. Multiplying each digit of 12 by 778 individually and then adding the results provides the final answer, which is 9336.
Explanation:
The student's question involves performing a multiplication operation, specifically 12 multiplied by 778. To solve this without a calculator, one can use a standard multiplication technique as follows:
Write down the two numbers, with 778 above 12.
First, multiply 2 (the rightmost digit of the lower number) by 778 to get 1556.
Next, multiply 1 (the leftmost digit of the lower number) by 778 and remember to add a zero at the end (because it represents the tens place), which gives us 7780.
Add the two results, 1556 and 7780, to get the final answer, which is 9336.
The result of 12 times 778 is 9336.

amelia and 2 of her friends went out to lunch. each girl ordered exactly the same meal. the total cost 55.08, which included 8% sales tax. what was the price of each meal, not including tax?
Answers
108% = 55.08
1% = 55.08 ÷ 108 = $0.51
100% = $51
3 meals = $51
1 meal = $51 ÷ 3 = $17
Answer: $17
Answer:
$16.8912
Step-by-step explanation:
We are given that Amelia and her two friends went out to lunch.
If each girl ordered exactly the same meal.
We have to find out the value of price of each meal without tax.
Total cost of meals=$55.08
Cost of 3 meals with tax=$55.08
Sales tax=8% of $55.08
8% of 55.08=[tex]\frac{8}{100}\times55.08[/tex]
8% of 55.08= $4.4064
Cost of 3 meals without tax=$55.08-$4.4064=$50.6736
Cost of each meal=[tex]\frac{50.6736}{3}=[/tex]$16.8912
Hence, the cost of each meal without tax=$16.8912
Two functions are represented in different ways. Function 1: y = 32x + 45 Function 2: x y 0 65 1 85 2 105 3 125 Which statements are true? Select each correct answer. Function 1 has a greater rate of change than function 2. Function 2 has a greater rate of change than function 1. Function 1 has a greater y-intercept than function 2. Function 2 has a greater y-intercept than function 1.
Answers
rate of change = 32
y-intercept = 45 when x = 0
Function 2: x y 0 65 1 85 2 105 3 125
rate of change = (85-65)/(1-0) = 20
y-intercept = 65 when x = 0
So the following statements are correct:
Function 1 has a greater rate of change than function 2.
Function 2 has a greater y-intercept than function 1.
Answer:
Step-by-step explanation:
Function 1: y = 32x + 45 <- 45 is y-intercept
Function 2: x y 0 65 <- 65 is y-intercept
So Function 2 has a greater y-intercept than function 1.
Function 1: y = 32x + ... <- 32 is rate of change
Function 2: x y 0 65 1 85
rate of change = 85 - 65 = 20
So Function 1 has a greater rate of change than function 2.

A camera manufacturer spends $2,100 each day for overhead expenses plus $9 per camera for labor and materials. The cameras sell for $14 each. a. How many cameras must the company sell in one day to equal its daily costs? b. If the manufacturer can increase production by 50 cameras per day, what would their daily profit be?
Answers
B. If they sold an extra 50 cameras a day, since they make $5 a camera, that would give them an extra profit of $250 a day.
B. For making 50 more cameras each day, they'd make $250 dollars more per 50 cameras.
A. To find this, you can simply multiply 420 by $14. This will give you how much they make from selling that many cameras ($5,880). Next you need to multiply 420 by 9 (labor an material cost per camera), then add $2,100 (expenses). This will give you the same cost ($5,880), thus making them equal, and proving 420 is the answer.
B. To find this, you do the same steps as above, by replacing 420 with 470, (470*$14 = $6,580) and (470*9 + $2,100 = $6,330). Then you subtract $6,330 from $6,580. Thus getting $250.

The explanation is shown below:
1. As you can see in the figure attached, the blue parabola has the function f(x)=x^2. This is the patern function. By definition, this is the most basic function of the quadratics functions.
2. The red parabola is shifted 2 units to the -y axis and is wider than the first one, by multiplying the variable x. Therefore. As you can see, the correct function that represents this parabola is the function of the option D
3. If you want to verify it, you can give values to x and plot each point on a graph.
a) F(x) is wider than G(x)
This can be obtained by multiplying the function by a value with magnitude less than 1.
b) F(x) is shifted down
This can be obtained by subtracting a number from the function value.
From the given option, only option D satisfies these conditions.
So, the correct answer is option D

Morgan uses 1/4 of her supply of raisins to make trail mix and 3/8 of her supply of raisins to make cookies. If Morgan uses 5 pounds of raisins, how many pounds of raisins are in her supply?
Answers
There are 8 pounds of raisins in Morgan's supply.
Let us say there are 'a' pounds of raisins in her supply.
What is a fraction?Fraction is a manner to represent part of a whole.
Raisins used to make trail mix = 1/4 of a = 1/4 a
Raisins used to make cookies = 3/8 of a = 3/8 a
It is given that:
Morgan uses 5 pounds of raisins,
[tex]\frac{1}{4} a+\frac{3}{8} a=5[/tex]
[tex]\frac{5}{8} a = 5\\\\a=8[/tex]
Therefore, there are 8 pounds of raisins in Morgan's supply.

Morgan's total supply of raisins is 8 pounds.
Let's denote the total supply of raisins by R. According to the problem, Morgan uses 1/4 of her supply to make trail mix and 3/8 of her supply to make cookies. Together, this amounts to a total of five pounds of raisins used.
We set up the equation to represent the total amount of raisins used:
1/4 R + 3/8 R = 5
We need to find a common denominator to combine the fractions. Here, the common denominator is 8:
(2/8) R + (3/8) R = 5
Combining the fractions gives:
(5/8) R = 5
To isolate R, we multiply both sides of the equation by the reciprocal of 5/8, which is 8/5:
R = 5 * 8/5
When we simplify, we get:
R = 8
So, Morgan's total supply of raisins is 8 pounds.

Final answer:
The value of the expression (a-1) + a^2 - b^2 / (1-ab) + 2(a - b) / (2b) when a=2 and b=-1 is -5/3.
Explanation:
To calculate the given expression when a=2 and b=-1, we first plug these values into the expression, which is (a - 1) + a^2 - b^2 / (1 - ab) + 2(a - b) / (2b). After substitution, it simplifies as follows:
The term (a - 1) becomes (2 - 1), which equals 1.
The term a^2 - b^2 becomes 2^2 - (-1)^2, which simplifies to 4 - 1 = 3.
The denominator 1-ab becomes 1 - (2)(-1), which equals 1 + 2 = 3.
The term 2(a - b) becomes 2(2 - (-1)), which is 2(3) = 6.
The denominator 2b becomes 2(-1), which is -2.
Now, the full expression simplifies to (1 + 3) / 3 + 6 / -2. Simplifying further, we get 4 / 3 + (-3), which equals to 4/3 - 3/1. After finding a common denominator, the expression simplifies to (4 - 9) / 3, which is -5/3.
Therefore, the value of the expression when a=2 and b=-1 is -5/3.

area = 22.5 ft²
Explanation:
The total area can be calculated by summing the areas of the rectangle and the triangle.
1- getting the area of the rectangle:
area of square = length * width
In the given, we have:
length = 4 ft
width = 5 ft
Therefore:
area of rectangle = 4 * 5 = 20 ft²
2- getting the area of the triangle:
area of triangle = 0.5 * base * height
In the given, we have:
base = 5 ft
height = 1 ft
Therefore:
area of triangle = 0.5 * 5 * 1 = 2.5 ft²
3- getting the total area:
Total area = area of rectangle + area of triangle
Total area = 20 + 2.5 = 22.5 ft²
