Answer:
3x = 45
they can form <u>15</u> three-person teams
Step-by-step explanation:
45 / 3 = 15
Answer:
Step-by-step explanation:
a) The standard deviation is usually preferred over the range because it is calculated from all of the data and will not be impacted as much as the range when they are outliers,and the standard deviation uses all of the data.
b)The IQR sometimes referred to the standard deviation when there is an outlier because the IQR is less sensitive to this features than standard deviation.
that is the IQR is not affected by an outlier,while the standard deviation is affected by an outlier.
c)The advantage of the standard deviation over the IQR is the standard deviation takes into account the values of all observation,while the IQR uses only some of the data.
Answer:
X=8
Step-by-step explanation:
Cross multiply:
4 * 6 = x * 3
Simplifying
4 * 6 = x * 3
Multiply 4 * 6
24 = x * 3
Reorder the terms for easier multiplication:
24 = 3x
Solving
24 = 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
24 + -3x = 3x + -3x
Combine like terms: 3x + -3x = 0
24 + -3x = 0
Add '-24' to each side of the equation.
24 + -24 + -3x = 0 + -24
Combine like terms: 24 + -24 = 0
0 + -3x = 0 + -24
-3x = 0 + -24
Combine like terms: 0 + -24 = -24
-3x = -24
Divide each side by '-3'.
x = 8
Simplifying
x = 8
Answer:
Step-by-step explanation:
We get possible sums from 1 + 1 = 2 to 6 + 6 = 12 when we toss two dices together. Total ways 6*6 = 36
a.
<u>Prime numbers:</u>
- 2, 3, 5, 7, 11 - total 5 outcomes with 15 ways (1+1, 1+2, 1+4, 1+6,2+1, 2+3, 2+5, 3+2, 3+4, 4+1, 4+3, 5+2, 5+6, 6+1, 6+5)
b.
<u>Perfect squares:</u>
- 4, 9 - total 2 outcomes with 3 ways for 4 (1 +3, 2+2, 3+1) and 4 ways for 9 (3+6, 4+5, 5+4,6+3)
- P(perfect square) = (3 + 4)/36 = 7/36
c.
<u>Perfect cube:</u>
- 8 - one outcome with 5 ways (2+6,3+5,4+4,5+3,6+2)
- P(perfect cube) = 5/36
