Thomas needed a load. he borrowed 24,000$ from the bank at a rate of 8.25% of simple interest for 36 months. what was the total

spayn [35]

Step-by-step explanation:

principal= 24000$

rate=8.25%

time=36months=3years

now,

simple interest =PTR/100

=24000×8.25×3/100

=594000/100

=5940

so,

amount=simple interest +principal

=5940+24000

=29940$

he had to pay back 29940$

A survey of 80 randomly selected companies asked them to report the annual income of their presidents. Assuming that incomes are

Artyom0805 [142]

Answer:

The 90% confidence interval estimate of the mean annual income of all company presidents is ($579,545, $590,580).

Step-by-step explanation:

The information provided is:

$n=80\\\sigma=30,000\\\bar x=585062.50\\\text{Confidence level} = 90\%$

The critical value of <em>z</em> for 90% confidence level is, 1.645.

Compute the 90% confidence interval estimate of the mean annual income of all company presidents as follows:

$CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}\\\\=585062.50\pm 1.645\times\frac{30000}{\sqrt{80}}\\\\=585062.50\pm5517.50\\\\=(579545, 590580)$

Thus, the 90% confidence interval estimate of the mean annual income of all company presidents is ($579,545, $590,580).

This interval implies that there is 90% probability that the true mean annual income of all company presidents is within this interval.

Name the property used to make the conclusion. If x=3, then 5x=15.

bulgar [2K]

Note that both sides were multiplied by 5.

So that would be "Multiplication Property of Equality."

Basically, this property states that if a=b, then ac = bc.
