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.

Locate and label the following fraction on the number line 1/2 4/2 5/2

LuckyWell [14K]

1/2 would be in between 0 and 1. The fraction 4/2 is actually 2, so it would just be plotted on the number 2 on the number line. 5/2 is reduced to 2.5, therefore it goes in between 2 and 3.

The table shows the total cost, y, for renting a playroom for a party with x party guests.

tatyana61 [14]

Answer:

y = 9x + 175

Step-by-step explanation:

Choose one value for y in the table, for example, 211. All the equations have 9x, so multiply the corresponding x for 9:

9•4 = 36

Now make the value of y - 36:

211 - 36 = 175

Now you have the equation:

y = 9x +175

Two percent of Jennie’s skin cells were burned when she escaped from a fire. If 3.7×10^10 of her skin cells were burned then, ho

gulaghasi [49]

$1813\times10^9$ cells were not burnt when Jennie escaped from the fire.

<u>Solution:</u>

Given:

2% of skin cells were burnt i.e, $3.7\times10^{10}$ of skin cells were burnt.

To find:

Number of skin cells that were not burnt

We can write $3.7\times10^{10} \text{ as } 37\times10^{9}$

Therefore, by equating the values we get,

2% of the cell is $37\times10^9$

1% of the cell is $\frac{37\times10^9}{3}=18.5\times10^9$

As, 1% of the cell is $18.5\times10^9$

98% of the cell will be $98\times18.5\times10^9=1813\times10^9$

$\therefore \text{ skin cells that are not burnt is } 1813\times10^9$
