The median is the middle number, the range is the difference between the lowest and highest values(subtract the lowest number from the highest number) and the mode is the number that appears most often in a set of numbers
Hope this helps
Answer:
The answer to your question is letter D
Step-by-step explanation:
Formula
m∠E = 
Data
m∠E = 48°
DGF = 228°
DF = x°
Substitution
48° = 
Solution
2(48) = 228 - x°
96 = 228 - x°
96 - 228 = - x°
- 132 = - x°
x° = 132°
Answer:
I must say i don't but i feel like it would be way easier then how my home school is doing it
Its 26.315% or rounded to 26.32% commission
Explanation; you take the total of the car, and then divide that by the exact amount Ken earned leaving you with the commission
18,250 ÷ 693.50 = 26.315789474 (normally using only the first two decimals when counting money, rounded to the nearest tenth) leaving you with 26.32
Answer:
Expected value = 190
Variance = 4000
Step-by-step explanation:
Let X be the number of the trials until the third success of the bad pump.
This implies that X is a negative binomial distribution
having θ = 20% = 0.2.
Now, if for example it will take X trials to use up the three pumps, then the total time is 10 min/trials + extra 10 minutes for the 3 bad pumps
This means the total time is written as;
T = 10X + (10 + 10 + 20)
T = 10X + 40
Mean which is also expected value of X is;
μ_x = 3/0.2 = 15
Variance of X is; σ²_x = 40
Thus;
Mean of T will be;
μ_T = 10μ_x + 40
μ_T = 10(15) + 40
μ_T = 190
Also, variance of T will be;
σ²_T = 10²•σ²_x
σ²_T = 100 × 40
σ²_T = 4000
