8/15
Explication étape par étape:
Prendre:
Longueur = x
Largeur = y
Zone du rectangle = Longueur * largeur
Un cinquième de longueur = x / 5
Un tiers de largeur = x / 3
Zone d'origine = xy
Nouvelle dimension:
Longueur = x + x / 5 = (5x + x) / 5 = 6x / 5
Largeur = x + x / 3 = (3y + y) / 3 = 4y / 3
Nouvelle zone = 6x / 5 * 4y / 3
Nouvelle zone = (24/15) xy
Fraction de la nouvelle zone par rapport à la zone d'origine:
(24/15) xy: xy
24/15: 1
24/15
= 8/5
The prime factorization of 88 is 11 x 2 x 2 x 2 the only factor of 88 that prime numbers are 2 and 11
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.

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:
Step-by-step explanation:
<u>Given that,</u>
3 hours = 180 miles
Divide 3 to both sides
3/3 hour = 180/3 miles
1 hour = 60 miles
So, Mom drove 60 miles in one hour.
