ElenaW [278]

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Decrease rate (d)= 7%

Number of periods (n)= 7 years

Current population (PV)= 48,000

First, to calculate the future value, we need to use the following decrease exponential formula:

FV= PV*[(1+d)^-n]

After 7 years:

FV= 48,000*(1.07^-7)

FV= 29,892

In a normal distribution, what is the probability that a data value will fall below the

Serga [27]

Answer:

A 99.96%

Step-by-step explanation:

The z score shows by how many standard deviations the raw score is above or below the mean. The z score is positive if the raw score is above the mean while the z score is negative if the raw score is below the mean. The z score is given by:

$z=\frac{x-\mu}{\sigma} \\\\where\ z=z-score,\ x=raw\ score,\mu=mean, \ \sigma=standard\ deviation\\\\For\ a\ sample\ size(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }$

The probability can be gotten from the normal distribution table. Therefore from the normal table:

P(z < 3.37) = 0.9996 = 99.96%

nadya68 [22]

Answer:

B. 54

Explanation:

Take 72 from 180.

180 - 72 = 108.

Since there are two y's AND they're congruent, divide 108 by two and get 54.

Write an equation in slope intercept form for the following graph.

Umnica [9.8K]

Y = -1/2x + 3
Why?
Looking at the line start where the line intercepts the y line, it goes down one over 2 and that’s your slope, the 3 is bc that’s where the line crosses the y line
