Say again? I can help, I just need you to restate your question :)
Answer:
3
Step-by-step explanation:
Intersections on the x axis occur when y = 0. f(x) is another term for y, so set f(x) equal to zero and solve for the two possible x's.
0 = x^2 - 3x - 40
0 = (x-8)(x+5)
By solving for x, you get 8 and -5. 8 and -5 added together will equal 3.
Y=5. Just substitute 1 in for x because a coordinate in (x,y) and then when you do that you get ...
y=3(1) +2
y=3+2
y=5
(1,5)
Answer:
the answer is option c
c)60
Step-by-step explanation:
From the given statement 2 × 3 mixed factorial design where 2 is a factor which is within the subject and
3 is the subject between the subject
then observation per cell where participants will need is 3* 20 = 60 because 3 is the factor between the subject.
