Answer:
B(-6, 0)
Step-by-step explanation:
You want to find B such that ...
(B -A) = (3/4)(C -A) . . . . the required distance relation
4(B -A) = 3(C -A) . . . . . . multiply by 4
4B = 3C +A . . . . . . . . . . add 4A, simplify
Now, we can solve for B and substitute the given coordinates:
B = (3C +A)/4 = (3(-6, -2) +(-6, 6))/4 = (-24, 0)/4 = (-6, 0)
The coordinates of point B are (-6, 0).
Hope it helped u if yes mark me BRAINLIEST!

Answer:
4m +3 marbles does Helena have in all.
Step-by-step explanation:
Here, m represents the marble in each bag.
She put them in 4 bags with m marbles in each bag.
In each bag she have m marbles
then, in 4 bag she have 4m marbles
⇒total number of marbles= 4m
Since, she had 3 marbles left over.
⇒She have total number of marbles = 4m + 3
Therefore, 4m +3 marbles does Helena have in all.
Given :
p = 0.68
margin of error, E = 0.1
99% confident interval
alpha, α = 1 - 0.99
= 0.01

∴
(z-critical value)
Sample size = 


= 144.37
= 145 (rounded off)
Therefore, there are 145 businesses does she need to sample to meet this criteria.
