Answer: B. 11%
Step-by-step explanation:
Let A = Event that students eat breakfast in the morning.
B= Event that students floss their teeth.
We are given P(A)=57%=0.57
P(B)=80%=0.80
P(A∩B) = 46% =0.46
Now, the probability that a student from this class eats break feast but does not floss their teeth :-

Hence, the probability that a student from this class eats break feast but does not floss their teeth= 11%
The height of the person when an anthropologist finds a human femur of length will be 183.94cm.
<h3>How to calculate the height?</h3>
In order to calculate the height, the expression to use will be:
h = 1.876l + 84.512
h = 1.876(53) + 84.512
h = 99.428 + 84.512
h = 183.94
Therefore, the height is 183.94cm.

Answer:
4(5+k)
Step-by-step explanation:
20+4k

4k = 2*2*k
The common factors are 2*2 = 4
We can factor out a 4
What is left over is inside the parentheses
4(5+k)

or
feet per inch
Step-by-step explanation:
Yeah. This is a question about scaling.
Basically, it's asking how many feet (in real life) are being represented by one inch in the blueprint.
You solve it by dividing the height of the actual house by the height of the blueprint. And, since the actual house is in feet, and the blueprint is in inches, your answer will be in feet per inches.
