Answer: 0.79
Step-by-step explanation:
I will suppose that this is not a continuos probability, as the individual probabilites add up to 100%.
If you want to obtain the probability that x ≤ 0, then you need to add the probability for the cases x= 0, x = -1, x = -2 .... etc
This is:
x = 0, p = .16
x = -2, p = .33
x = -3, p = .13
x = -5, p = .17
Then, the probability where x takes a negative value or zero {-5, -3, -2, 0} is:
P = 0.16 + 0.33 + 0.13 + 0.17 = 0.79
Answer:The score above the mean is 50 percent.

Answer:
40
Step-by-step explanation:
*this is a 90 degree triangle
so we will use Pythagorean theorem to get X
hypotenuse²=side of right triangle²+the other side of right triangle²
so
50²=30²+x²
2500=900+X²
2500-900=x²
1600=x²
x=√1600
=40
so the answer is 40

Vertex is either the coordinates of the maximum or the minimum
Answer:
D. 200
Step-by-step explanation:
Laticia doing her survey on a sample that has a size of about 25% of the population. That means the sample is approximately four times larger than the sample she takes. Unless its ratio or percentage, any data she takes will be 1/4 of the population. If 51 student of her sample choose summer as their favorite, predicted number on the population will be:
51 * (100%/25%)=
51 * 4= 204
The number will be around 200.
