Answer:
The probability of landing on the heads side of the coin and rolling 3 on the number cube is 0.083.
Step-by-step explanation:
Given:
Coin is tossed and a single 6 sided number cube is rolled.
Let the event of tossing head be 'H' and event of rolling a 3 be 'R3'.
Now, we know that:
Probability of an event 'A' = Favorable outcomes of 'A' ÷ Total possible outcomes
Now, for tossing a coin, the total possible outcomes are head and tail. So, there are 2 possible outcomes.
So, probability of event 'H' is given as:
Similarly, for rolling a 6 sided cube, the possible outcomes are numbers 1 to 6. So, the number of possible outcomes is,
Now, probability of rolling a 3 is given as:
Now, both the events 'H' and 'R3' occur together. So, the combined probability is the product of two individual probabilities as they are independent events. So,
Note: Independent events are those events whose intersection is an empty set of events or the outcome of one event doesn't affect the outcome of the other event.
Therefore, the probability of landing on the heads side of the coin and rolling 3 on the number cube is 0.083.

x = 2
Step-by-step explanation:
Similar triangles are triangles which have the same shape but not the same size. This means their angle measures are equal but their side lengths are not instead they are proportional. To solve, we will set up a proportion and solve.
A proportion is two equal ratios set equal to each other. We form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). Out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:
.
To solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
