The probability that x will be at most 2 will be 0.89.
<h3>What is probability?</h3>
It should be noted that probability simply means the likelihood of the occurence of an event that's given.
Based on the information, let the number of points that can be scored on the statistics examination be depicted by x.
Therefore, the probability that x will be at most 2 will be:
= P(x = 0) + P(x = 1) + P(x = 2)
= 0.13 + 0.21 + 0.55
= 0.89
Therefore, the probability that x will be at most 2 will be 0.89.

Answer:
1. 40.00 sq units
2. 37.5 sq units
Step-by-step explanation:
1. Given slant height as 3 and the square base side as 4,
-The surface area of a right squared pyramid is calculated by summing the areas of the 4 triangles and the square base:
Hence, the area of the square pyramid is 40.00 sq units
2. The surface area of a cube is equivalent to 6 times the side of one face.
-Given the dimension of the sides as 2.5, surface area is obtained as:
Hence, the surface area of the cube is 37.5 sq units
Answer:
Step-by-step explanation:
Given
Balls = 1 to 4
Required
Determine the probability of selecting ball numbered at least 2
Here, we'll assume that all numbers have the same probability.
The probability of each ball will be:
So:
Recall that
--- for each ball
So, the equation becomes
X and y represent the two students.
Teacher wants to spend at least $5 in each of x and y. That means x or y could be either equal to 5 or higher than 5.
x ≥ 5
y ≥ 5
Teacher only spends under $30. That means the sum of x and y couldn't be equal to higher than 30. It should be lower than 30.
x + y < 30
The correct answer is option D
As the value of X increases, the value of y would decrease, due to this relationship being an inverse variation. ... An inverse variation would be similar to a linear relationship because in both, values can increase, as others decrease, and it would pretty much be it, because there aren't much similarities between them.
