Answer:
Step-by-step explanation:
Given that a survey showed that 72% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight
X - number of people who need correction for their eyesight
X is binomial since each event is independent and there are only two outcmes.
X (18, 0.72)
Required probability = the probability that no more than 1 of them need correction for their eyesight.
=P(X=0)+P(X=1)=0.00000296+0.000137
=0.00014
Yes 1 is a significantly low number as probability is almost zero.
Amount of chocolate milk Ana drinks = 
liter
Total amount of chocolate milk in refrigerator = 
liter
We have to determine the total number of glasses she will pour liter of milk from liter of milk.
Total number of glasses will be determined by dividing the total amount of milk by the amount of milk required for one glass
Total number of glasses = 
= 
= 
= 5.6 glasses
So, 5.6 glasses will be poured from the given amount of chocolate milk.
Answer:
Y=×^2-9
Step-by-step explanation:
(X+0)^2-9
Use the vertex form, y=a(x-h)^2+k
a=1
h=0
k=-9
And because the parabola opens up the vertex is (0,-9)
The distance from the vertex to a focus of the parabola by using the __ 1/4a__ formula:
1/4(1)
1/4
(h,k+p)
(0,-35/4)
When a set of data is divided into quarters, the quarters are known as QUARTILES.
