The Miller family wants to join a public swimming pool that charges a fee of $25.00 per year and then $3.00 for each visit.
1 answer:
Answer:
B) Yes
C) C = 3x + 25
Step-by-step explanation:
Given that:
Yearly charge = $25
Charge per visit = $3
The yearly cost will depend on the number of visits for the year :
B.) Cost can be represented by a linear function, as the graph it yields is a straight line graph having intercept and slope.
C.) C = mx + b
Where ;
b = intercept = yearly cost
m = slope or gradient = cost per visit
C = total cost
x = number of visits
Hence,
C = 3x + 25

Answer:
0.0076 = 0.76% probability that all five plants emerged from treated seeds
Step-by-step explanation:
The plants were chosen without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x successes is given by the following formula:
In which:
x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this question:
6 + 6 = 12 seeds, which means that
6 treated, which means that
Five sprouted, which means that
What is the probability that all five plants emerged from treated seeds?
This is P(X = 5). So
0.0076 = 0.76% probability that all five plants emerged from treated seeds
