Let’s assume that human body temperatures are normally distributed with a mean of 98.20° F and a standard deviation of 0.62° F.

uysha [10]

Answer: It is such a small percentage of the population that would be considered to have fever at that level.

So, it is not appropriate stringent standard.

Step-by-step explanation:

Since we have given that

Mean = 98.20°F

Standard deviation = 0.62°F

If Bellevue Hospital in New York City uses 100.6°F as the lowest temperature considered to be a fever.

So, $\bar{X}=100.6^\circ F$

So, using the normal distribution, we first find the value of z.

$z=\dfrac{\bar{x}-\mu}{\sigma}\\\\x=\dfrac{100.6-98.2}{0.62}\\\\z=3.87$

Since z = 3.87

So, p = 0.0001 =0.1%

So,It is such a small percentage of the population that would be considered to have fever at that level.

So, it is not appropriate stringent standard.

Volume of a cone = 3.14 x 0.75^2 x 2/3
= 3.14 x 0.5625 x 2/3
= 1.76625 x 2/3
= 1.1775 = 1.18 feet^3

The bill for a meal at a restaurant before tax is $84.00. the sales tax rate is 7% and you want to leave a 20% tip based on the

Strike441 [17]

The pree tax amount count as 100%, then there's the 7% tax and lastly the 20% tip. therefore, one would pay (100+20+7)% of $84.00.
127% of $84.00
(127/100) * $84.00 = $106.68

lakkis [162]

Answer:

Total cost of repayment $= 4955.04$

Net interest paid $= 655.04$

Step-by-step explanation:

Given

Amount taken on loan $= 4300$

Repayment plan

Monthly installment $=$ $206.46$

Yearly installment $= 206.46 * 12 = 2477.52$

Rate of interest per year $= 14$ %

Time Period for repaying the loan $= 2$ years

The total amount repaid by Jameson at the rate of $206.46$ per month for next $24$ months

$= 206.46 *24\\= 4955.04$

Net interest paid

$= 4955.04 - 4300\\= 655.04$

Total cost of repayment $= 4955.04$

Net interest paid $= 655.04$
