That point will be where the perpendicular line through the origin intersects the given line.
.. (-1/4)x = 4x +3
.. -3 = (17/4)x
.. -12/17 = x
The point on the given line that is closest to the origin is (-12/17, 3/17).
Step-by-step explanation:
3(6+b)+2b+1
18+3b+2b+1
5b+19
Answer:
We can represent a number in general by x . Halving a number means dividing it by two, so the expression that shows the half of a number is x2 , since you divide a number by two.

Answer:
5%
Step-by-step explanation:
This is a significance test for a mean.
The 2 hypothesis here will be:
To determine the z-score of the error in the means you have to use this formula:
This mean that if the z score of a significance level is less than 1.897 the hypothesis that μ>2,200 is suggested.
10% -> z= 1.28
5% -> z = 1.645
1% -> z = 2.33
The most restrictive level of significance is 5%
