Answer:
1 1/4 liters of paint
Step-by-step explanation:
Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1LaTeX: \frac{3}{5}3 5 doors. How many liters of paint are needed for 1 door?
From the above question, we can deduce that:
2 liters of paint covers 1 3/5 doors
Hence:
1 3/5 doors = 2 liters of paint
1 door = x liters of paint
Cross Multiply
1 3/5 doors × x liters = 2 liters × 1 door
x liters = 2 liters × 1 door/ 1 3/5 doors
x liters = 2 ÷ 1 3/5
x liters = 2 ÷ 8/5
x liters = 2 × 5/8
x liters = 5/4 liters
x liters = 1 1/4 liters of paint
Hence: 1 1/4 liters of paint is needed for 1 door
Answer:
I think the total number of combinations of 3 from 6 = 6C3 = 20
All possible combinations of 3 which have a product divisible by 3 must contain either a 3 or a 6.
So the number not divisible must be 3 combinations from the number 1, 2, 4, and 5.= which is 4
So the required probability is 20-4 ? 20 = 16/20 = 0.8 Answer
Hope this help you! :)
This is called as sampling error or sampling variability. Sampling
error is the variability that happens because the value of a sample statistic varies
from sample to sample. Sampling error is acquired when a population is estimated
from a subset, or sample.
