The Andersons can set up 30 tables in 5 hours, as the problem deals with direct proportion. The calculation is 6 tables/hour * 5 hours = 30 tables.
The problem we're dealing with is a direct proportion scenario, where the number of tables the Andersons can set up increases linearly as time increases. It states that they can set up 6 tables in 1 hour. To find out how many tables they can set up in 5 hours, you simply multiply the rate (6 tables/hour) by the amount of time (5 hours).
So, 6 tables/hour * 5 hours = 30 tables. Therefore, the Andersons can set up 30 tables in 5 hours.

Using the binomial distribution, it is found that there is a 0.0369 = 3.69% probability that 3 or more were involved in an accident last year.
For each driver, there are only two possible outcomes, either they were involved in an accident, or they were not. The probability of a driver being involved in an accident is independent of any other driver, hence, the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
In this problem:
The probability is:
In which:
Then
0.0369 = 3.69% probability that 3 or more were involved in an accident last year.

Answer:
Therefore the probability that 3 or more were involved in an accident last year is 0.376.
Step-by-step explanation:
Binomial distribution:
A discrete random variable X having the set {0,1,2.....,n} as the spectrum, is said to have binomial distribution with parameter n= the number of trial and p = probability of getting successes in one trial if the p.m.f of X is give by
for x=0,1,2,....,n
=0 elsewhere
where , n is a positive integer and 0<p<1.
Given that,
7% of all drivers were involved in an accident last year that was determined by a car insurance company.
p= 7%=0.07, n=11, x=3
P(X≥3)
= 1-P(X≤2)
= 1- P(X=0)-P(X=1)-P(X=2)
=1-0.624
≈0.376
Therefore the probability that 3 or more were involved in an accident last year is 0.376.
Answer:
29.03 cm
Step-by-step explanation:
Step one:
given
A rectangular block of metal is
25cm long
11cm wide and
9cm high.
The volume of the block is
= 25*11*9
= 2475cm^3
Required
The dimension of an equivalent cube
we know that volume of cube
v=l^3
24475=l^3
cube root both sides
l= ∛24475
l= 29.03 cm
Answer:
13.5cm
