Alice works at a health care facility. she has measured the hemoglobin levels of 200 people. the data follows a normal distribution with a mean of 14 g/dl and a standard deviation of 1.
from the given data, we can conclude that about people have hemoglobin levels less than 13, and about people have hemoglobin levels greater than 14.

Step-by-step explanation:

Given that Alice works at a health care facility. She has measured the hemoglobin levels of 200 people.

Let X be the hemoglobin level of a person

Then X is normal (14, 1)

For X<13, we have

z<-1

Hence probability = 0.16

i.e. 16% or32 people will have hemiglobin below 13.

People who have greater than 14

X>14 means z>0

Hence exactly 50% or 100 people will have hemiglobin levels >14

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
