Answer:

Step-by-step explanation:
We are given that
Sophomores=13
Juniors=12
Seniors=8
Male sophomores=5
Female sophomores=6
Male seniors=4
We have to find the probability of randomly selecting a junior or a senior.
Total persons=13+12+8=33
Let A=Seniors
B=Juniors
Probability,P(E)=
Using the formula of probability







Hence, the probability of selecting a junior or senior=
Given that out of 30 planted seeds only 9 of the m sprouted, then:
Experimental probability =(number of occurrence of event)/(total number of trials made)
=9/30
=3/10
thus the number of seeds that will sprout given that 20 seeds we planted will be:
3/10×20
=6 seeds
Answer:
The domain and range of function is the set of all possible inputs and outputs of a function respectively.
The domain and range of a function y = f (x) is given as domain= {x ,x∈R }, range= {f (x), x∈Domain}.
The domain and range of any function can be found algebraically or graphically.
Answer:
-2
Step-by-step explanation:
9g-4-5=-27
9g-9=-27
Add 9 to both sides
9g=-18
g=-2
