Answer:

equation is y=20(3)^x

Step-by-step explanation:

example:

Solve for x over the integers:

20 (3)^x = 4860

Divide both sides by 20:

3^x = 243

243 = 3^5:

3^x = 3^5

Equate exponents of 3 on both sides:

Answer:

x = 5 hours open with 4860 guest

A sample of 100 footballs showed an average air pressure of 13 psi. The standard deviation of the population is known to be .25
Vladimir79 [104]

Answer:

0.025 is the standard error of mean.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 100

Sample mean = 13 psi

Population standard deviation = 0.25 psi

We have to find the standard error of the mean.

Formula:

Standard error =

\dfrac{\sigma}{\sqrt{n}} = \dfrac{0.25}{\sqrt{100}} = \dfrac{0.25}{10} = 0.025

0.025 is the standard error of mean.

slope(m) = -4
(-2,5)....x = -2 and y = 5
now we sub into the formula and find b, the y int
5 = -4(-2) + b
5 = 8 + b
5 - 8 = b
-3 = b

so ur equation is : y = -4x - 3 <==
