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%

The equation is true because both sides are identical.

7 is 1/10 of what number
umka21 [38]
We should find the original number, 7 of 1/10. We divide the known number for the numerator, than multiply for denominator.

7 : 1 = 7 * 10 = 70 <- answer

So 7 is 1/10 of 70

We can check our work:

1/10 of 70 = 7?

70 : 10 = 7*1 = 7
