Calculate the range of the data set
33,38,35.5,39.25,31.75
Answers
The range of the given data set, 33, 38, 35.5, 39.25, 31.75, is 7.5. The range represents the spread or the difference between the highest and lowest values in the data set.
To calculate the range of a data set, you need to find the difference between the maximum and minimum values.
Given the data set: 33, 38, 35.5, 39.25, 31.75
To determine the maximum value, we can compare the numbers in the data set and identify the highest one. In this case, 39.25 is the largest number.
To find the minimum value, we compare the numbers and identify the smallest one. Here, 31.75 is the smallest number.
Now, we can calculate the range by subtracting the minimum value from the maximum value:
Range = Maximum value - Minimum value
= 39.25 - 31.75
= 7.5

What is P(not odd)? if u roll a 6-sided die
Answers
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
We have to find the probability of not getting odd, whole rolling a 6 sided die ~
Actually dices have 3 odd numbers (1 , 3 , 5) and 3 non - odd numbers (2 , 4 ,6)
When we roll a dice, we may get any of the six numbers, so total possible outcomes are 6
and, The number of Favorable outcomes is 3, i.e non - odd numbers.
[tex] \qquad \sf \dashrightarrow \: p(not \: odd) = \dfrac{favourable \: outcomes}{total \: \: outcomes} [/tex]
[tex] \qquad \sf \dashrightarrow \: p(not \: odd) = \dfrac{3}{6} [/tex]
[tex] \qquad \sf \dashrightarrow \: p(not \: odd) = \dfrac{1}{2} \: \: \: or \: \: \: 0.5[/tex]
Answer:
½
Step-by-step explanation:
Not odd (even) numbers from 1 - 6 = 2, 4, 6
Any of these 3 numbers can come when rolling a cubical 6 - sided dice.
Then,
P (not odd)
= Favourable outcomes / total number of outcomes
= 3/6
= ½

Find (a) the range and (b) the standard deviation of the data set 141,116,117,135,126,121. round to the nearest hundredth if necessary.
Answers
a) The range of the given data set is 25.
b) The standard deviation of the given data set is 10.1.
The given data set is 141, 116, 117, 135, 126, 121.
a) The range is the difference between the highest and lowest values within a set of numbers.
Range = Highest value - Lowest value
= 141-116
= 25
So, the range is 25.
b) Set up the formula for sample standard deviation. The standard deviation of a set of values is a measure of the spread of its values.
[tex]s=\sqrt{\frac{(x_i-\bar x)^2}{n-1} }[/tex]
Here, mean ([tex]\bar x[/tex]) = [tex]\frac{141+116+117+135+126+121}{6}[/tex]
= 126
[tex]s=\sqrt{\frac{(141-126)^2+(116-126)^2+(117-126)^2+(135-126)^2+(126-126)^2+(121-126)^2}{6-1}}[/tex]
[tex]s=\sqrt{\frac{(15^2+(-10)^2+(-9)^2+(9)^2+(0)^2+(-5)^2}{5}}[/tex]
[tex]s=\sqrt{\frac{(225+100+81+81+25)}{5}}[/tex]
[tex]s=\sqrt{\frac{512}{5}}[/tex]
s=10.1
So, the standard deviation is 10.1.
Therefore,
a) The range of the given data set is 25.
b) The standard deviation of the given data set is 10.1.

An extension cord 6 yards long costs $8.46. What is the price per foot? There are 3 feet in 1 yard.
Submit
Answers
The extension cord is an illustration of unit rates, and the price per foot is $0.47 per foot
How to determine the price per foot?The given parameters are:
Length = 6 yards
Cost = $8.46
Convert the length from yard to feet.
So, we have:
Length = 6 feet * 3
This gives
Length= 18 feet
The price per foot is then calculated using:
Rate = Cost/Length
This gives
Rate = 8.46/18
Evaluate
Rate = 0.47
Hence, the price per foot is $0.47 per foot

Claire says that she can find the volume of any cylinder as long as she can measure the circumference and height is she correct
Answers
Answer:
Yes, she is correct. Volume of the cylinder is V = πr²h. Therefore we need height and radius to calculate the volume. Height is given and the radius can be calculated from the circumference.
Step-by-step explanation:
Volume of cylinder
[tex]V = \text{area of circle} \times \text{height}\\V = \pi r^2 \times h[/tex]
For the volume of the cylinder we need the radius of the circle and height of the cylinder. The height is already known.
We can find the radius from the circumference.
Cirumference of the circle
[tex]C = 2 \pi r[/tex]
We can get the radius from rearranging the equation.
[tex]r = \frac{C}{2 \pi}[/tex]
Since C (circumference) is known we can easily calculate the radius.
With that we have all the needed information (height and radius) to calculate the volume of the cylinder.
