Answer:
2,3,4
Step-by-step explanation:
the reason why is because there is no tally for 2,3,4
Answer:
Option B is correct - this experiment has one factor (shampoo type), blocked by gender and whether the hair is dyed.
Step-by-step explanation:
The researcher desires to compare the effect of a new type of shampoo, he also has the opinion that men and women may react to the shampoo differently.
Furthermore, he believes that the shampoo will react differently to the hair that is dyed.
Therefore, this experiment has one factor(shampoo-type), blocked by gender and whether the hair is dyed.
Hence, option B is the correct option.
A parabola ALWAYS has a lowest point like unless it would be upside down.
How to solve:
You would calculate two of the numbers to get the vertex.
Paralell ines have same slope
perpendicular lines have slopes that multiply to -1
y=mx+b is slope intercept
m=slope
b is irrelivant for this problem
solve for y first
5x+7y=12
7y=-5x+12
y=-5/7x+12/7
paralell is same slopoe but differnt b
y=-5/7x+b
sub (5,2)
(x,y)
2=-5/7(5)+b
2=-25/7+b
29/7=b
y=-5/7x+29/7
perpendcular
-5/7 times what=-1
what=7/5
y=7/5x+b
(5,2)
2=7/5(5)+b
2=7+b
-5=b
y=7/5x-5
it’s 93 and 1/2 :)) there you go
