Answer:
(c) 
will be perpendicular to the line y = 3x+2
Step-by-step explanation:
We have given the the equation of line as y = 3x+2
We know the equation of line as y = mx+c , here m is slope and c is intercept
On comparing with standard equation of line m = 3
We know that slope of perpendicular line is 
So the slope of the line which is perpendicular to y = 3x+2 will be 
Now (a) Line is given as 
its slope is 
so it will be not perpendicular
(b) Line is given as 
its slope is so it will be not perpendicular
(c) Line is given as its slope is 
so it will be perpendicular to the line y = 3x+2
(d) Line is given as 
its slope is 3 so it will not perpendicular to the line y = 3x+2

To find the volume of a sphere:
3.14≈π
Now since its telling us to use π, then we do our formula by multiplying by π.
π=3.14 (Approximate amount)
So:
So you are correct.
When Radius=9, you plug in for R. :)

-3x + 10 = 34
Subtract 10 from both sides:
-3x = 24
Divide both sides by -3:
X = 24 / -3
X = -8

I have two questions to solve
-3x+10=34
13x-4=11x+10-8
Combine like terms on the right side:
13x -4 = 11x + 2
Subtract 11x from both sides:
2x -4 = 2
Add 4 to both sides:
2x = 6
Divide both sides by 2:
X = 6/2
X = 3
The size of the sample they should take to estimate p with a 2% margin of error and 90% confidence is n = 1691.
In statistics, the margin of error is just the degree of a significant error in the outcomes of random sample surveys.
The formula of margin error is, E = z√((p-vector)(1 - (p-vector)) ÷ n)
E = 2% = 0.02
Confidence level = 90%
Now, the proportion is not given so adopt nominal (p-vector) = 0.05
The critical value at CL of 90% is 1.645.
Thus, making n the subject,
n = z²(((p-vector) × (1 - (p-vector))) ÷ E²)
n = 1.645²((0.5 × 0.5) ÷ 0.02²)
n = 1691.266
n ≈ 1691
