PLS HELP ME OUT REWARD GUARANTEE!!!!!!!!!!!!!The fat content for seven different sandwiches at a restaurant is 42, 61, 13, 9, 12, 42, and 62. Find the mean, median and mode of the fat contents.

Answers

Answer 1
Answer: Mean: subtract the smallest number from the biggest number...62-9=?Median: the middle number, order the numbers from smallest to biggest....Mode: the number that is repeated the most...This should help you. I do not want to give you the answers. I want you to do them yourself with the instructions I gave you and then come back and post them when you are done so I may check them. Okay?
Answer 2
Answer: Mean: \bar{x} = (x_(1) + x_(2) + x_(3) + x_(4) + x_(5) + x_(6) + x_(7))/(n)
           \bar{x} = (42 + 61 + 13 + 9 + 12 + 42 + 62)/(7)
           \bar{x} = (241)/(7)
           \bar{x} = 34(3)/(7)

Median: 9, 12, 13, 42, 42, 61, 62
                              42

Mode: 42

d.
as one value increases, the other decreases
This is because when both values are multiplied, you get a constant so if one is increased the other needs to be reduced so their product can meet up with the constant

y = 8x − 2, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs? A{(0, −2), (1, 6), (2, 14)} B{(0, −2), (2, 13), (−5, −40)} C{(1, 7), (2, 7), (3, 7)} D{(1, 6), (2, 13), (3, 24)}

Answers

Answer: The correct option is (A){(0, −2), (1, 6), (2, 14)} .

Step-by-step explanation:

y = 8x-2

  • (0, −2) putting, x = 0 and y = -2

   -2 = 8(0) - 2

    RHS =LHS

  • (1, 6) putting x = 1 and y = 6

    6 = 8(1) - 2

    RHS =LHS

  • (2, 14) putting x = 2 and y = 14

    14 = 8(2) - 2

    RHS =LHS

Hence, all the coordinates in set (A) are satisfying the given function.
The answer is A, because all of the ordered pairs work when inputed into the function.

8(0) - 2 = -2

8(1) - 2 = 6

8(2) - 2 = 14

The correct answer is A.

A welder needs apiece of half-inch pipe18 3/4 in. Long.  she has a piece the is 28 1/8 in. Long. how much must she cut off from the longer piece?

Answers

I got 9 and 3/8 because you would subtract 18 3/4 from 28 1/8 

Final answer:

The welder needs to cut off 9 3/8 inches from the longer piece.

Explanation:

To determine how much the welder needs to cut off from the longer piece of pipe, we need to find the difference between the lengths of the two pieces.

Given that the longer piece is 28 1/8 inches and the desired length is 18 3/4 inches, we can subtract the desired length from the longer piece's length:

28 1/8 - 18 3/4 = 9 3/8

Therefore, the welder needs to cut off 9 3/8 inches from the longer piece of pipe.

#SPJ2

The force of an object (f) is equal to its mass (m) times its acceleration (a). Thus, the formula for calculating force is f = ma. Based on this information, which of the following equations would be used to calculate acceleration?A. a = f ÷ m
B. a = f − m
C. a = f + m
D. a = fm

Answers

The correct answer is A. To rearrange the equation, you have to divide both sides by "m" to isolate "a" so that acceleration can be directly calculated. This would result in the equation becoming: f/m = ma/m As the mass (m) on the right hand side of the equation appears in the numerator and the denominator, it can be cancelled, resulting in the new equation: f/m = a which can then be flipped to give a = f/m.

The sum of two positive numbers is 55 times their difference. What is the ratio of the larger number to the smaller number?

Answers

so x and y
sum means add
difference means subtract
so we have
x+y=55 times (x-y)
use distributiver property which is
a(b-c)=ab-ac so
distribute 55(x-y)
55(x-y)=55x-55y

so we have
x+y=55x-55y
add 55y to boh sides
x+56y=55x
subtract x from both sides
56y=54x
divide both sides by 2
28y=27x
to find the ratio, switch the numbers around
ratio of y:x=27:28
therefor x is the greater number
ratio of larger to smaler is
28:27
11 * 5 = 55.

In this case 5 would be the smaller number and 11 would be the bigger number.
those two numbers are our ratio's, The sum of them combined is 55.

i hope this helped you.
