Answer:
Step-by-step explanation:
3rd one
Answer:
34/24
Step-by-step explanation:
x-3/4+2/3=17/12
x-17/12=17/12
X=17/12+17/12
X=34/24
We need to define our outcomes and events.
Finding the probability<span> of each event occurring
separately, and then multiplying the probabilities is the step to <span>finding
the probability</span> of two
independent events that occur in
sequence.
</span>
<span>
To solve this problem, we take note of this:</span>
The roll of the two dice are denoted by the pair
(I, j) ∈ S={ (1, 1),(1, 2),..., (6,6) }
Each pair is an outcome. There are 36 pairs and each has
probability 1/36. The event “doubles” is { (1, 1),(2, 2)(6, 6) } has
probability p= 6/36 = 1/6. If we define ”doubles” as a successful roll, the
number of rolls N until we observe doubles is a geometric (p) random variable
and has expected value E[N] = 1/p = 6.
Answer:
<u>The missing side is 12 cm length</u>
Step-by-step explanation:
1. Let's review the information given to us to solve the case correctly:
Length of the longest side= 13 cm
Length of one leg = 5 cm
2. Using the Pythagorean theorem for finding the length of the second leg, because this is a right triangle:
2nd leg² = Length of the longest side ² - Length of one leg²
2nd leg² = 13 ² - 5 ²
2nd leg² = 169 -25
2nd leg² = 144
2nd leg = √144
2nd leg = 12 cm
<u>The missing side is 12 cm length</u>
