Answer:
Option D. 1.29x + 1.35y ≤ 12
Step-by-step explanation:
Nick is making a fruit salad.
He buys apples per pound for = $1.29
He buys oranges per pound for = $1.35
He spend no more than $12.00 or we can say less than equal to $12
Let x represent the number of pounds of apples that Nick buys and y represent the number of pounds of oranges.
Cost of x pounds of apples = $1.29x
Cost of y pounds of oranges = $1.35y
Total cost = 1.29x + 1.35y
Total cost should be less than equal to $12.00
Therefore, inequality will be 1.29x + 1.35y ≤ 12
Option D. is the answer.
Answer:
B(0.7, 100)
Step-by-step explanation:
Probability of contracting a certain disease = 0.70
No of individual randomly selected = 100
Contracting the disease is a positive/success in this case, hence
p = 0.7 and since there are 100 selection, the binomial distribution B(0.7, 100)
Hence, the The random variable describing the number of individuals who will contract the disease is B(0.7, 100) distribution.
And Mean = 0.7 x 100 = 70
