Well, gee !

You're asking for the diameter and the radius, so I guess
"9 yards" is not the diameter or the radius.

So WHAT IS "9 yards" ?

If students’ scores were normally distributed and the mean was 200 with a standard deviation of 40, then what is the probability

Sonja [21]

Answer:

84%

Step-by-step explanation:

The empirical rule tells you that 68% of the standard normal distribution is within 1 standard deviation of the mean. The distribution is symmetrical, so the amount in the lower tail is (1 -68%)/2 = 16%.

Since the number you're interested in, 240, is one standard deviation above the mean (200 +40), the percentage of interest is the sum of the area of the central part of the distribution along with the lower tail:

68% + 16% = 84%.

25m/s to miles/h Can anyone solve it? With explanation if you can

Dimas [21]

25 meters per second x 60 seconds = 1500 meters per minute

1500 meters per minute x 60 minutes per hour = 90,000 meters per hour

1 mile = 1609.34 meters

90000/1609.34 = 55.92 miles per hour

round answer to either 55.9 or 56 mph depending on what you need.
