Yes, the smaller the standard deviation the closer the results are clustered around the mean.
Standard deviations measure the spread of the values in a data set. The more spread out the values, the higher the standard deviation.
5.20/4.16=1.25
5.20 is apples
4.16 is $
1.25 is $ per pound
the area and circumference ones are correct. a quadrilateral has 4 sides, so that one is incorrect. hope this helps!
Answer:
Volume = 1330.6cm³
Step-by-step explanation:
Step one
This problem bothers on the mensuration of solid shapes a cylinder.
We know that the volume of a cylinder is expressed as
V= πr²h
Step two
Given data
Base of the cylinder /diameter = 11cm
Hence radius = 11/2= 5.5cm
Length /height of cylinder = 14cm
Step three
Substituting our given data we have
Volume = 3.142*(5.5)²*14
Volume = 3.142*30.25*14
Volume = 1330.637cm³
to 1 decimal place we have
Volume = 1330.6cm³
1) The probability of rolling a 1 is 10/40 and the probability of rolling a 5 is 6/40. Add these together to get 16/40 which simplifies to 2/5 probability of rolling a 1 or 5.
2) The probability of the spinner landing on section 2 is 36/80 which simplifies to 9/20
3) To find the relative frequency, divide each number by the total number of trials. In this case we're only look at the clubs so divide 8/40, which is 0.2 or 20%
4) There were 60 trials total and since we're finding the relative frequency of red, divide 13/60 which is 0.216 rounded to 0.22 or 22%
5) The spinner is spun 84 times and it lands on A 14 times so the probability of it landing on A is 14/84 which simplifies to 1/6 or 0.166 rounded to 0.17 or 17%
I hope this helps you!
