A 6 sided number cube is tossed. what is the probability of rolling a 6 or an odd number?
Veronika [31]
For any probability the formula is P_{desired}=\frac{desired}{total}. In this case we have 4 desired outcomes (the odds, 1, 3 and 5, and also 6) out of 6 total sides, so our probability P_{oddor6} =\frac{odd or 6}{total sides}=\frac{4}{6} = \frac{2}{3}.

Mutually exclusive means the events cant occur at the same time. In our case it is not possible to roll both a 6 and an odd number at the same time since 6 is even. Therefore the events ARE mutually exclusive. 

Combine the two parts and C is the correct answer.  <span />

What is the solution to 5x-6y&gt;42
Shalnov [3]

Answer:

y< 5/6 - 7

Step-by-step explanation:

First, you have to send 5x to the other side so youĺl -5x and the equation will be -6y>-5x+42

Then, you divide the equation on the left side by -6 because youll want y by itself. Remember, when you divide by a negative, you flip the greater than/equal to sign. itll now be y<-5/6 - 7

done

{4x+2y=10<br> y=2x-1<br><br>What is the value of x+y<br><br>A.3.125<br>B.2<br>C.4.5<br>D.3.5​
Evgen [1.6K]

Answer:

D.3.5

Step-by-step explanation:

4x+2y=10(given)

2x+y=5

y=5-2x-----(1)

y=2x-1------(2)(given)

Since the left side of the equations are the the same,

5-2x=2x-1

4x=6

x=1.5

Sub x=1.5 into eq(1),

y = 5-2(1.5) = 5-3 = 2

so, x+y = 1.5+2 = 3.5
