Answer:
Step-by-step explanation:
Perimeter = 2(l + w)
Perimeter = 464inches
Length l = 100inches
: 464 = 2(100 + w)
Dividing be 2
464/2 = 100 + w
232 = 100 + w
Collecting like terms
232 - 100 = w
132 = w
It is 132 inches long
She would need to work for 35 hours.
She earned $250.25 total the first two weeks, so divide that by the new rate per hour, $7.15, to get the 35 hours.
Answer:
a) P(x=5) = 0.2456
b) P(x≥6) = 0.3526
c) P(x<4) = 0.1887
Step-by-step explanation:
We can model this as a binomial experiment, with sample size n=10 and p=0.49.
To calculate the probability of having k subjects with very little confidence in the sample of 10, we solve:
a) We have to calculate P(x=5).
For a binomial variable with n=10 and p=0.49, this can be calculated as:
b) We have to calculate P(x≥6). This can be calculated as:
c) We have to calculate P(x<4). That is:
Answer:
The answer would be B. With equations, what you do to one side you have to do to the other.
