Z score of 0 gives you the mean for the problem;  The mean μ is 70 Now you can use this value of the mean in the definition of z score for the second case and find the standard deviation. Z score is the number of standard deviations away from the mean.  Therefore σ = (1)(74-70) = 4.

Which equation represents a line that passes through (2, - 1/2) and has a slope of 4 ?
solmaris [256]

Answer:

y=4x-8.5

y-y₁=m(x-x₁)

Plug coordinates and slope in.

y-(-1/2)=4(x-2)

Solve

y+1/2=4x-8

y=4x-8.5

Anuta_ua [19.1K]

Answer:

10,93,500.

Step-by-step explanation:

On first February total number of rabbits were 500.

Now it is given that after each month rabbit population will become triple of initial.

So, after one month rabbits will become 3×500.

After two months they will become 3^{2}×500.

Thus , after m months total number of rabbits will become 3^{m}×500.

Now,

On August 1 , 7 months will get passed from February 1 so putting m = 7 in the equation we get ,

Total number of rabbits = 3^{7}×500 = 10,93,500.
