A taxi charges $1.75 plus a fee of $0.75 for each mile traveled.the total coast of a ride without a trip is $4.75 how many miles

Alisiya [41]

y = .75x + 1.75

4.75 = .75x + 1.75

4.75 - 1.75 = 3

3 = .75x

3/.75 = 4

The trip is 4 miles.

The compressive strength of concrete is normally distributed with mu = 2500 psi and sigma = 50 psi. A random sample of n = 8 spe

ipn [44]

Answer:

The standard error of the sample mean is _17.677_ psi.

Step-by-step explanation:

<u>Explanation</u>:-

A random sample of n = 8 specimens is collected.

Given sample size is n = 8

Given mean of the population 'μ' = 2500 psi

standard deviation 'σ' = 50 psi

Let x⁻ is the mean of the observed sample

Standard error of the sample mean = $\frac{S.D}{\sqrt{n} }$ ...(i)

Given Population of standard error (S.D) 'σ' = 50 psi

Now substitute all values in (i)

$S.E = \frac{50}{\sqrt{8} } =17.677$

<u>Conclusion</u>:-

The standard error of the sample mean is _17.677psi.
