Answer:

$220

Step-by-step explanation:

5/01: Beg. inventory: 10 × $10 = $100

5/03: Add inventory: 10 × $12 = $120

5/08: Less inventory: (10 × $12) + (2 × $10) = $140

5/15: Add inventory: 10 × $14 = $140

5/31: End. inventory: (10 × $14) + (8 × $10) = $220

(3-4i)(-2-21) multiply
evablogger [386]

Answer:

-69 +92 i (here 'i' is imaginary value)

Step-by-step explanation:

step:-

Given (3-4 i)(-2-21)

on multiplication, we get

(3-4 i)(-2-21) = 3(-2) -3(21) - 4 i (-2) +4 i(21)

                    = -6 -63 + 8 i +84 i

                    = -69 +92 i

-69 + 92 i is a complex number.

real part x = -69

imaginary part y = 92

1 3/4 = 7/4

Then add.

11/4 + 7/4 = 18/4

1. A poll conducted in 2018 found that 54% of US adult Twitter users get at least some news on Twitter. The standard error for t
Harrizon [31]

Answer:

The 99% confidence interval for the fraction of US adult Twitter users who get some news on Twitter is (0.4872, 0.6018). It means that we are 99% sure that the true proportion of US adult Twitter users who get some news on Twitter is between 0.4872 and 0.6018.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm zs

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}, and s is the standard error.

54% of US adult Twitter users get at least some news on Twitter.

This means that \pi = 0.54

The standard error for this estimate was 2.4%

This means that s = 0.024

99% confidence level

So \alpha = 0.01, z is the value of Z that has a pvalue of 1 - \frac{0.01}{2} = 0.995, so Z = 2.575

The lower bound is:

\pi - zs = 0.54 - 2.575*0.024 = 0.4782

The upper bound is:

\pi + zs = 0.54 + 2.575*0.024 = 0.6018

The 99% confidence interval for the fraction of US adult Twitter users who get some news on Twitter is (0.4872, 0.6018). It means that we are 99% sure that the true proportion of US adult Twitter users who get some news on Twitter is between 0.4872 and 0.6018.
