Answer: f(2)=15, f(-2)=18, all real #s
Step-by-step explanation:
1. f(2)=4(2)^2-2+1=16-1=15
2. f(-2)=4(-2)^2-(-2)+1=16+3=18
Answer:
I think 3/4 will be the answer if you let
(-5 2) =(x1 y1)
(3 8) =( x2 y2)
y1-y2/x2-x2
8-2/3+5
6/8
3/4
Answer: 8gml
Step-by-step explanation:
Answer:
a. P(both stat)=0,36
b. P(both math)=0,16
c. P( at least one sstatt)=0,84
d. P( at least on smath)=0,64
Step-by-step explanation:
Number of students= 5
Number of students math majors=2
Number of students statistics majors=3
a. Probability that both selected students are statistics majors
P(x)=3/5*3/5=0,36
b. Probability that both students are math majors
P(x)=2/5*2/5=0,16
c. Probability that at least one of the students selected is a statistics major
P(sstat)=3/5=0,6
P(not sstat)=2/5=0.4
P(sstat)=1-P(not sstat)∧n
P( at least on sstat)=1-0.4∧2=0.84
d. Probability that the selected students have different majors
P(smath)=2/5=0,4
P(not smath=2/5=0.6
P(smath)=1-P(not smath)∧n
P( at least on smath)=1-0.6∧2=0.64
