Answer:
$2.85
Step-by-step explanation:
The price Ellen pays can be found using the proportion ...
price/(24 oz) = $1.90/(16 oz)
Multiplying by 24 oz, we get ...
price = $1.90(24/16) = $2.85
Ellen pays $2.85 for the beans.
Answer:
The vertex is at ( 3.5, -0.25)
and the axis of symmetry is x = 3.5.
Step-by-step explanation:
Convert to vertex form:
y = x^2 - 7x + 12
y = (x - 3.5)^2 - 3.5^2 + 12
y = (x - 3.5)^2 - 0.25
y = (x - 3.5)^2 - 0.25.
So the vertex is at ( 3.5, -0.25)
and
the axis of symmetry is x = 3.5.
Answer: 0.884736
Step-by-step explanation:
Given: The proportion of all air travel departs on time: p= 0.96
Total flights : n= 3
Let x be the number of flights on time.
As there are two cases either flight on time or not, so it is a binomial case.
Binomial distribution formula:
The probability that all of them depart on time =
The probability that all of them depart on time = 0.884736
I think It's B. A = 5 x 9
