The radius of a circle is 18 yards. What is the circle's area?<br> Use 3.14 for .

IrinaVladis [17]

Solution:

<u>We know that:</u>

Radius: 18 yards
πr² = Area of circle
π = 3.14

<u>Finding the area of the circle:</u>

(π)(r²) = Area of circle
=> (3.14)(18²) = Area of circle
=> (3.14)(324) = Area of circle
=> Area of circle = 3.14 x 324 = 1017.36 yards²

The burning time of a very large candle is normally distributed with mean of 2500 hours and standard deviation of 20 hours. Find

dezoksy [38]

Answer: C.-1.5

Step-by-step explanation:

Given: The burning time of a very large candle is normally distributed with mean $(\mu)$ of 2500 hours and standard deviation $(\sigma)$ of 20 hours.

Let X be a random variable that represent the burning time of a very large candle.

Formula: $Z=\dfrac{X-\mu}{\sigma}$

For X = 2470

$Z=\dfrac{2470-2500}{20}\\\\\Rightarrow\ Z=\dfrac{-30}{20}\\\\\Rightarrow\ Z=\dfrac{-3}{2}\\\\\Rightarrow\ Z=-1.5$

So, the z-score they corresponds to a lifespan of 2470 hours. =-1.5

Hence, the correct option is C.-1.5.
