Answer:
A. True
Step-by-step explanation:
The empirical rule in statistics states that:
- 68% of the data will be within 1 standard deviation
- 95% of the data will be within 2 standard deviations
- 99.7% of the data will be within 3 standard deviations
So yes, we can state that 5% or less of the data will be more than 2 standard deviations away from the mean. Of course, statistics is not 100% certain, so this rule is not 100% right all the time. Some exceptions might result, but generally speaking, the results should follow the empirical rule.
The area means to multiply the length by the width.
let's solve.
14 1/2 x 13 1/4.
convert our fractions into decimals.
14 1/2 = 14.50
13 1/4 = 13.25
Now we can multiply properly.
14.50 x 13.25 = 192.125
since our shape is 2-Dimensional, our units are ^2.
Your area is:
192.25 ft^2
Answer:
the bus took 4.5 hrs going 60 kph to get from town P to town Q
this means that the distance from town P to town Q is 270 km
side note-the car kph isn't shown and it got to town Q faster than the bus, so it must have gone at a faster speed. i didn't use the car to solve the problem, just the bus.
38 cm sum of all sides is equal to the perimeter
Yes. That's correct. Is that what you're asking...? To clarify, prime numbers have a single factor (one and itself) , composite numbers have multiple factors.
