Answer:
k = 12
Step-by-step explanation:
Given 3k = 36 we want to isolate the variable (k) using inverse operations
So we want to get rid of the 3
3k = 3 times k (multiplication)
The inverse of multiplication is division so to get rid of the * 3 we want to divide by 3. Remember whatever we do to one side we have to do to the other side so we are going to divide each side by 3
3k/3=k
36/3=12
we're left with k = 12

Given
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

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
