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.

A public library has an aquarium in the shape of a rectangular prism. The base is 6 feet by 2.5 feet. The heigh is 4 feet. How m

topjm [15]

sides 2 * 6 * 4 =48 and 6*4=24

bottom 6*2.5 =15

2.5*4=10

10*2=20 that's the area of 2 smaller sides

Step-by-step explanation:

we add up the dimensions together 48+20+15=83

so the final equation becomes (6*2.5)+2(2.5*4)+2*(6*4)=83

Could someone break it down. I am not catching on.

sleet_krkn [62]

$\bf -0.04y+0.11(9000-y)=0.35y
\\\\\\
-0.04y+990-0.11y=0.35y
\\\\\\
990-0.15y=0.35y\implies 990=0.35y+0.15y
\\\\\\
990=0.50y
\implies 
\cfrac{990}{0.5}=y\implies 1980=y$

This is the picture to my last question. sorry

erma4kov [3.2K]

Answer:

Step-by-step explanation:

The point A has coordinates (5, 1) so the image of A which is A' has

coordinates (5 - 2, 1+3)

= (3, 4).

B', C' and D' are calculated in the same way.

So B' is (4, 1),

C' = (3, 2) and

D' = (2, 1)
