Mathematics

Answer:

a. 80%

b. £34

c. £340

Step-by-step explanation:

a. We are given that Mrs Trent spent 20% of her weekly wage on food. This means she would have 80% of her weekly wage left with her.

b. 10% of Mrs Trent weekly wage:

If 20% = £68

10% = (10*68)/20 = £34

c. Let x represent weekly wage of Mrs Trent

Given that she spends £68 of x (weekly wage) on food, which is 20% of x.

This means that, 20% of x = £68

Let's find her weekly wage, x:

\frac{20}{100} * x = 68

0.2x = 68

Divide both sides by 0.2

x = 340

Her weekly wage is £340.

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.
