1. B
Adding a constant offset to the data does not change its variance. Scaling it, or applying a non-linear function will change the variance.
2. A
For a given number on the 3rd die, the first two dice can match it 11 ways, or have two numbers that match in 5 additional ways. Thus probability of 2 or more numbers being the same is 6*16/216 = 4/9.
Don’t mind this comment just need points but good luck
Answer:
3. B = Median
4. A =skewed right
Step-by-step explanation:
15% of what is 24
0.15x = 24
x = 24/0.15
x = 160 workers
We need first to find the capacity of the paint tray
4 cms = 4/2.54 = 1.5748 inches
capacity of the tray = 14 * 10 * 1.5748 = 220.47 in^3
1 gallon = 231 in^3 so the overfill of paint will be 231 - 220.47 = 10.53 in^3
The last option is the correct one.
