Step-by-step explanation:
First, let x represent this unknown number because we are using an equation to solve this. Note that 'of' means multiplication.
First we cross out to get;
30 = 
Then we multiply both sides of the equation by 3
90 = 2x
Now since we want x to stand alone, we divide both sides by 2
45 = x
So the answer is 45
<u>Second Problem</u>
First we find how far Ken jumps.
1 ÷ 5 = 0.2. If this is attached to the one it means Ken jumped 1.2 metres.
To find how much further Steve jumped, we just have to subtract Ken's distance from Steve's distance.
1.5 - 1.2 = 0.3 metres
This means Steve jumped 0.3 metres further than Ken.
Examples of conjunctions are and, but, or, yet. So your answer would be A. I hope this helped. :)

Answer:If a die is rolled once, determine the probability of rolling a 4: Rolling a 4 is an event with 1 favorable outcome (a roll of 4) and the total number of possible outcomes is 6 (a roll of 1, 2, 3, 4, 5, or 6). Thus, the probability of rolling a 4 is 1/6.
If a die is rolled once, determine the probability of rolling at least a 4: Rolling at least 4 is an event with 3 favorable outcomes (a roll of 4, 5, or 6) and the total number of possible outcomes is again 6. Thus, the probability of rolling at least a 4 is 3/6 = 1/2
Step-by-step explanation:For example, when a die is rolled, the possible outcomes are 1, 2, 3, 4, 5, and 6. In mathematical language, an event is a set of outcomes, which describe what outcomes correspond to the "event" happening. For instance, "rolling an even number" is an event that corresponds to the set of outcomes {2, 4, 6}. The probability of an event, like rolling an even number, is the number of outcomes that constitute the event divided by the total number of possible outcomes. We call the outcomes in an event its "favorable outcomes".
