the sale price of an iphone is 179.00. if the percent discount was 20% what was the original price of the iphone?

Tju [1.3M]

100 - 20 = 80
179.00 = 80%
179.00 / 80 = 2.2375 = 1%
1% x 100 = 100%
So, 2.2375 x 100 = 100%
Therefore the original price was 223.75

What percent of 365 is 146? Also how do you get the answer thanks :)

EleoNora [17]

Percent literally means per one-hundred so:

365(p/100)=146 multiply both sides by 100

365p=14600 divide both sides by 365

p=40%

A sample proportion of 0.44 is found. To determine the margin of error for this statistic, a simulation of 100 trials is run, ea

salantis [7]

Answer:

margine of error = $\pm$ 0.13

Step-by-step explanation:

given data

sample proportion = 0.44

simulation trials = 100

sample size = 100

point estimate = 0.44

minimum sample proportion = 0.32

maximum sample proportion = 0.50

solution

we will get here first z score that is express as

$z = \frac{x-\mu }{\sigma }$ ............1

here x = 0.32and 0.50

$\mu = 0.44\\\sigma = \frac{x(max) - x(min)}{4} \\\sigma = \frac{0.50 - 0.32)}{4} = 0.045$

so z will be

$z1 = \frac{0.50 - 0.44 }{0.045 } = 1.35\\z2 = \frac{0.32 - 0.44 }{0.045 } = -2.66$

so now we get here margin of error that is express as

margin of error = $\pm \ z \times \sqrt{\frac{p(1-p)}{n}}$ ................2

we use here z heighervalue

margin of error = $\pm \ 2.66 \times \sqrt{\frac{0.44(1-0.44)}{100}}$

margine of error = $\pm$ 0.13
