Hello : 
the area is : A=<span>πr²
</span> π ≃ 3.14     r : <span>ridus
</span>   <span>diameter = 2 r
</span>r = 18/2= 9 ft  
  A=3.14×9² = 254.34 ft²

Formula of the Area of a circle: π.R²

Diameter =18 ft so R ,te radius = 9ft

Hence area of this circle =π.(9)²= 81π ft²  OR  254.47 ft²

First, she needs to find her resting heart rate by counting her pulse for one minute immediately after she wakes up for 5 days i
andreyandreev [35.5K]

Answer:

63

Step-by-step explanation:

She finds her average resting heart rate to be 62 after  5 days.

That means, average of the 5 heart rate pulse=62

If the last day was 58 and all the other days were the same.

Let x be her pulse on the other days,

Then,

Average, 62=\dfrac{58+4x}{5}\\\text{Cross Multiply}\\58+4x=62 X 5\\\text{Suntract 58 from both sides}\\4x=(62X5)-58\\4x=310-58\\4x=252\\\text{Divide both sides by 4}\\x=63

Her pulse on all the other days is 63.

The table gives the probabilities that new cars of different models will have brake failure. The car model that is least likely
melamori03 [73]
<span>All the information we have are the probabilities, and what we need is the lowest number: so let's choose the smallest probability among the numbers: 0.0065%, B 0.0037%,C 0.0108%,D 0.0029%, E 0.0145%. The smallest of the numbers is 0.0029% -it starts with two 00s and the number that follows, 2, is smaller than all there others - so the smallest probability is in option D - and the model would be the corresponding model (but we're missing some information here) </span>

Goryan [66]
I believe the answer is 3/8. The whole portion of employees, which is translated as 8/8 is deducted by 5/8, which is the population of male employees.
