due in 5 minutes help! :( All CD’s are on sale for 20% this week. The CD is $9.99. What is the original price of the CD?

bekas [8.4K]

Answer:

$12.49

Step-by-step explanation:

The price right now = 0.8 * the original price

9.99 = 0.8*x

x=12.4875

x≈12.49

Sorry, I thought your problem meant that it was 20% the original price, not 20% off.

Shazia sells 25x^2+5x+5 flowers in one day. If she sells the same number of flowers each day for rs 5x each , how much money wil

Mumz [18]

Answer:

$Total = 625x^3 + 125x^2 + 125x$

Step-by-step explanation:

Given

$Flowers = 25x^2 + 5x + 5$

$Unit\ price = 5x$

Required

The total price for 5 days

First, calculate the total for a day.

$1\ day = Unit\ price * Flowers$

$1\ day = 5x * (25x^2 + 5x + 5)$

Open bracket

$1\ day = 125x^3 + 25x^2 + 25x$

For 5 days, the total will be.

Total = days * sales of a day

So, we have:

$Total = 5 * [ 125x^3 + 25x^2 + 25x]$

$Total = 625x^3 + 125x^2 + 125x$

The estimate of the population proportion should be within plus or minus 0.02, with a 90% level of confidence. The best estimate

Rudiy27

Answer:

The sample size required is 910.

Step-by-step explanation:

The confidence interval for population proportion is:

$CI=\hat p\pm z_{ \alpha /2}\sqrt{\frac{\hat p(1-\hat p)}{n} }$

The margin of error is:

$MOE=z_{ \alpha /2}\sqrt{\frac{\hat p(1-\hat p)}{n} }$

Given:

$\hat p = 0.16\\MOE= 0.02\\Confidence\ level =0.90$

The critical value of <em>z</em> for 90% confidence level is:

$z_{\alpha /2}=z_{0.10/2}=z_{0.05}=1.645$ *Use a standard normal table.

Compute the sample size required as follows:

$MOE=z_{ \alpha /2}\sqrt{\frac{\hat p(1-\hat p)}{n} }\\0.02=1.645\times \sqrt{\frac{0.16(1-0.16)}{n} }\\n=\frac{(1.645)^{2}\times 0.16\times (1-0.16)}{(0.02)^{2}} \\=909.2244\\\approx910$

Thus, the sample size required is 910.
