Answer:
0.942 is the required probability.
Step-by-step explanation:
We are given the following in the question:
x is a binomial random variable with n = 5 and p = 0.8.
Then,
where n is the total number of observations, x is the number of success, p is the probability of success.
We have to evaluate:
0.942 is the required probability.
Answer:
The correct option is
B) ACT scores account for 57.74% of the total fluctuation in GPA.
Step-by-step explanation:
By Exterior Angle Theorem, the sum of the 2 inner angles in the triangle will be equal to the exterior angle.
=> x + 48° = 66°, x = 18°.
Answer:
Step-by-step explanation:
Surface area of a cube = 6a²
When each dimension is doubled, Side =2a
Surface area = 6*(2a)² = 6 * 4*a² = 4*(6a²)
So, when each dimension is doubled, surface area is 4 times of the original surface.
a = 3a
Surface area = 6*(3a)² = 6 * 9 *a² = 9 *6a²
= 9 times the original area
a = 4a
Surface area = 6*(4a)² = 6* 16 * a²
= 16 * (6a²)
= 16 times of original area
