A rotating lawn sprinkler sprays water in a circular area of grass, as shown in the picture. The diameter of the circular area o

Ksenya-84 [330]

Answer:

The area the sprinkler sprays with water is 201.06 square feet.

Step-by-step explanation:

Step 1; It is given that the diameter of the circular area of grass that the sprinkler sprays with water is 16 feet. The diameter of a circle is equal twice its radius. So we divide the diameter by 2 to get its radius.

Radius of the circle = Diameter of the circle / 2 = 16 feet / 2 = 8 feet.

Step 2; The area of any given circle is π times the square of the radius. The radius of this circle is equal to 8 feet.

Area of the circle = π × r² = 3.1415 × 8 feet = 201.056 square feet.

What is the probability that a random sample of 1414 second grade students from the city results in a mean reading rate of more

Sonbull [250]

Answer with explanation:

Number of second grade students who are considered for sample =1414

Number of words that is being read in a Minute = 9292 words per minute

If number of students will be more than half of 1414, that is if, they can read or their reading rate is more than 9292 words per minute, then we can say that the sample chosen is Appropriate.

⇒Required Probability,that sample of 1414 students can read 9292 words per minute

$=\frac{707+x}{1414} \text{Where }, [1 \leq x\leq 707]$
