Solve the equation for the y-value and choose whether it is a direct variation or inverse variation.

muminat

Answer:

Step-by-step explanation:

the equation representing direct variation is

y = kx ← k is the constant of variation

The equation representing inverse variation is

y = $\frac{k}{x}$ ← k is the constant of variation

Given

3y = x ( divide both sides by 3 )

y = $\frac{1}{3}$ x ← equation representing direct variation

with k = $\frac{1}{3}$

HELP PLEASE! Describe the effects of a, h and k on each function. Describe any similarities or differences between the effects o

Marysya12 [62]

For all of these cases:

a: shrink the whole shape horizontally by a times (if a is negative, then it extends -a times)

h: left shift the shape h units (if h is negative, then it right shifts -h units)

k: up shift the shape k units (if k is negative, then it down shifts -k units)

In an effort to estimate the mean of amount spent per customer for dinner at a major Lawrence restaurant, data were collected fo

Answer:

The 99% confidence interval for the population mean is 22.96 to 26.64

Step-by-step explanation:

Consider the provided information,

A sample of 49 customers. Assume a population standard deviation of $5. If the sample mean is $24.80,

The confidence interval if 99%.

Thus, 1-α=0.99

α=0.01

Now we need to determine $z_{\frac{\alpha}{2}}=z_{0.005}$

Now by using z score table we find that $z_{\frac{\alpha}{2}}=2.58$

The boundaries of the confidence interval are:

$\mu-z_{\frac{\alpha}{2}}\times \frac{\sigma}{\sqrt{n} }\\24.80-2.58\times \frac{5}{\sqrt{49}}=22.96\\\mu+z_{\frac{\alpha}{2}}\times \frac{\sigma}{\sqrt{n} }\\24.80+2.58\times \frac{5}{\sqrt{49}}=26.64$

Hence, the 99% confidence interval for the population mean is 22.96 to 26.64
