Assume that human body temperatures are normally distributed with a mean of 98.22 degrees Upper F 98.22°F and a standard deviati
Anna35 [415]

Answer: 0.00102%

Step-by-step explanation:

Given : Human body temperatures are normally distributed with a mean of \mu=98^{\circ}Fand a standard deviation of s=0.61^{\circ}F

A hospital uses 100.6^{\circ}F as the lowest temperature considered to be a fever.

Let x be the random variable that represents the human body temperatures.

z=\dfrac{x-\mu}{s}

For x= 100.6, z=\dfrac{100.6-98}{0.61}=4.26229508197\approx4.26

Using normal distribution table for z-values for right-tailed area ,

P(x>100.6)=P(Z>4.26)=0.0000102=0.00102\%

Hence, the required probability = 0.00102%

Nora measured the angles of a triangle. Two of the angles measured 20° What was the measure of the third angle of Nora’s triangl
aivan3 [116]

Answer:

140°

Step-by-step explanation:

The sum of angle of a triangle is equal to 180°.

Two of the angles measured 20°.

We need to find the measure of the third angle of Nora’s triangle. let the third angle is x. So,

20+20+x = 180

40+x = 180

x = 180-40

x = 140°

So, the third angle of the triangle is 140°.

How many hours would you have to ride your bike at 10 mi/h to burn 550 calories? (Per Minute)
vesna_86 [32]

Answer:

The  time spend to burn energy is 3300 minutes  .

Step-by-step explanation:

Given as :

The speed at which the bike ride = 10 miles per hours

The energy burn while riding = 550 calories

Let The time spend to burn energy = t minutes

So, According to question

Time spend = \dfrac{\textrm Energy burn}{\textrm rate of ride}

i.e t = \dfrac{550}{10} hours

∴  t = 55 hours

So, in minutes

The time spend

1 hours = 60 min

∴ 55 hours = 60 × 55 = 3300 minutes

So, The spend to burn energy = t  = 3300 minutes

Hence The  time spend to burn energy is 3300 minutes  . Answer
