A roll of a six sided die
Required
Which of the options is true
A) P(Even) = 1/4 and P(Odd) = 3/4
In a die, we have:
[tex]S = \{1,2,3,4,5,6\}[/tex] -- sample space
[tex]E = \{2,4,6\}[/tex] --- Even
[tex]O = \{1,3,5\}[/tex] -- Odd
The probability of even is the number of even sides over total.
i.e.
[tex]P(Even) = 3/6[/tex]
[tex]P(Odd) = 3/6[/tex]
Hence, (a) is incorrect
(b) A) P(Even) = 1/2 and P(Odd) = 3/2
In (a), we have:
[tex]P(Even) = 3/6[/tex]
[tex]P(Odd) = 3/6[/tex]
Simplify each
[tex]P(Even) = 1/2[/tex]
[tex]P(Odd) = 1/2[/tex]
Hence (b) is true
Since (b) is true, (c) and (d) are false

Suppose a large labor union wishes to estimate the mean number of hours per month a union member is absent from work. The union decides to sammple 348 of its members at random and monitor the working time of each of them for 1 month. At the end of the month the total number of hours absent from work is recorded for each employee . if the mean and standard deviation of the sample are x = 7.5 hours and s = 3.5 hours, find a 99% confidence interval for the true mean number of hours a union member is absent per month. Round to the nearest thousandth.

Share R600 amongst Tom, Paul and Anne in the ratio : 3:4:5 respectively.
Step-by-step explanation:
Total Shares = 3 + 4 + 5 = 12 shares
12 Shares = R600
(12÷12) Share = R(600÷12)
1 Share = R50
(1×3) Shares = R(50×3)
3 Shares = R150
4 Shares = R(50×4) = R200
5 Shares = R(50×5) = R250
Tom Gets R150.
Paul gets R200.
Anne gets R250.

Answer:
y=9.75x+60
Step-by-step explanation:
We want our equation to look like y=mx+b
Let's start out by calculating the slope
[tex]\frac{118.5-89.25}{6-3}=9.75[/tex]
we have
y=9.75x+b
we know that when x= 3 y= 89.25
89.25=9.75(3)+b
solve for b = 60
