Answer:
the first one
Step-by-step explanation:
obviously
Because the surface area is of a 2-D SHAPE to find a area of a 2-D shape is l x w
Answer:
24 buckets
Step-by-step explanation:
Given that :
Dimension of rectangular block = 45 m by 38 m
A bucket of paint will cover 72m² of floor
Total area of floor : Length * Width
Total Area = (45m * 38m) = 1710 m²
Buckets of paint required :
Total area / Area per bucket
= 1710m² / 72m²
= 23.75 buckets
= 24 buckets
Answer:
The probability is 0.0428
Step-by-step explanation:
First, let's remember that the binomial distribution is given by the formula:
where k is the number of successes in n trials and p is the probability of success.
However, the problem tells us that when there isn't a number of trials fixed, we can use the geometric distribution and the formula for getting the first success on the xth trial becomes:

The problem asks us to find the probability of the first success on the 4th trial (given that the first subject to be a universal blood donor will be the fourth person selected)
Using this formula with the parameters given, we have:
p = 0.05
x = 4
Substituting these parameters in the formula and solving it, we get:

Therefore, the probability that the first subject to be a universal blood donor is the fourth person selected is 0.0428 or 4.28%
