Answer:
Mean = 84.9
Median = 89
Mode = 89
Step-by-step explanation:
89 , 76 , 89 , 89 , 100 , 71 , 80
First, we need to arrange in either ascending or descending order. In this case, let us arrange in ascending order:
71, 76, 80, 89, 89, 89, 100
1. The mean is simply the sum of all the variables divided by the number of variables
Mean = (71+76+80+89+89+89+100)/7
Mean = 594/7
Mean = 84.9
2. Median is the middle term of the distribution
Median = 89
3. Mode is the variable with the highest frequency i.e the variable that appears the most
Mode = 89
Answer:
A
Step-by-step explanation:
Using the definition
n
= 
where n! = n(n - 1)(n - 2).... × 3 × 2 × 1
Then evaluating numerator and denominator
10
= 
= 
Cancel 7(6)(5)(4)(3)(2)(1) on numerator/ denominator, leaving
= 
= 
= 120
-------------------------------------------------------------------------------------
6
= 
= 
Cancel 4(3)(2)(1) on numerator/ denominator, leaving
= 
= 15
-------------------------------------------------------------------------------------
Dividing numerator by denominator gives
= 8 → A
Answer:
Slope is 1/5 and equation is 4-2 / 10-0
Step-by-step explanation:
Its equation is 4-2 / 10-0
-2/-10 = 1/5 Slope is 1/5
The correct answer should be 20% because u were 80% certain he would remember so that means ur 20% certain he would forget
Step 1: You can distribute it by multiplying 6 by 2x and -12, so you get 12x-72= 24
Step 2: Now you can solve it by adding 72 on both sides, so we get 12x= 96, then you can divide 12 on both sides, so we get x=8.
