Answer:
add up all numbers
then divide that number by the amount of numbers.
Step-by-step explanation:
mad is basically finding the average of a set of numbers.
and how do you do that?
first, add up all numbers
ex: 1, 5,3,10,6,20,15,15,14 --> this adds up to 90.
then divide that number by the amount of numbers.
count how much numbers ehere are: there are 9 numbers.
divide 90 by 9 and the mad/average is 10.
plz give brainliestttt
Answer:
Here is an example..:
Find the M.A.D of the set of data
10.2 , 9.4, 11.3, 12.9
( so, we just have to add up all numbers )
10.2 + 9.4 + 11.3 + 12.9 = 43.8
Then we divide them by 4, you might be wondering..why 4?
that's because there are about 4 numbers in the data set.
So:
43.8
____= 10.95 (we found the mean! :D)
4
After that, we just have to subtract the mean (10.95) to the same numbers (or the so called data set)
10.95 - 10.2 = 0.75
10.95 - 9.4 = 1.55
10.95 - 11.3 = 0.35
10.95 - 12.9 = 1.95
For our final step, we just add up all the difference, then, divide it by 4 again.
0.75 + 1.55 + 0.35 + 1.95 = 4.6
--------- = 1.15
4

6 1/6- 5 3/4=x
1) convert the fractions to a common multiple like 12, but what the denominator is multiplied by so is the numerator
6 2/12- 5 9/12
2) subtract the 6 and 5 than subtract numerators
5/12 is the answer
b. Will your estimate be lower or higher than the actual amount April will save? How do you know?
Answer:
a. 5400
b. higher
Step-by-step explanation:
a. 3 yrs = 36 m
$146 ≈ $ 150
36 m * $150 / m = $5400
b. My estimate will probably be higher because I rounded up.
Answer:
185
Step-by-step explanation:
do the oppsite:
30+10=40
40-3=37
37x5=185
185/5=37
37+3=40
40-10=30
Answer: 3/10
Step-by-step explanation:
3/10 • 100 = 30%
If 1+8i and 1-8i are the equation's roots, then the quadratic equation is
x² - 2x + 65 = 0.
A quadratic equation is written in standard form as y = ax² + bx + c, where a, b, and c are simple numbers. A quadratic equation's factored form is denoted by the expression y = (ax + c) (bx + d), where a, b, c, and d are simple numbers.
Any quadratic problem can be solved using the quadratic formula. The equation is first changed to have the form ax² + bx + c = 0, where a, b, and c are coefficients. After that, we enter these coefficients into the following formula: (-b ± √(b² - 4ac)) / (2a).
If 1+8i and 1-8i are the equation's roots, then:
x - (1 + 8i) = 0 and x - (1 - 8i) = 0 then we get
x - 1 - 8i = 0 and x - 1 + 8i = 0
⇒ (x - 1 - 8i)(x - 1 + 8i) = 0
⇒ x² - x + 8ix - x + 1 - 8i - 8ix + 8i + 64 = 0
⇒ x² - 2x + 65 = 0
The quadratic equation is x² - 2x + 65 = 0.
