Answer:
18.95%
Step-by-step explanation:
In this case what we must do is calculate the probability of eating a jelly treats first and then another jelly treats, being the final probability the multiplication of these events.
We know that there are 20 in total and that initially there are 9 jelly treats, so the first event is the probability:
9/20
And the second event, with one less in each, would be:
8/19
The final probability then:
9/20 * 8/19 = 0.1895
So the probability of this happening is 18.95%
Option 1! If you expand the bracket and simplify.
1. To solve this problem, you must aplpy the formula for calculate the volume of a sphere, which is:
V=4/3(πr)
V is the volume of the sphere.
r is the radius of the sphere.
2. You must calculate the radiius. You have that the beach <span>ball has a diameter of 18 inches, then:
r=diametert/2
r=18 inches/2
r=9 inches
3. When you substitute r= 9 inches into the formula, you obtain:
</span><span>
V=4/3(πr)
V=3053.62 inches</span>³
Mathematical model is a description of a system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modeling.
Answer:
g = 0 or g = -1/2
Step-by-step explanation:
Solve for g:
8 g^3 - 2 g^2 = 2 g^3 - 5 g^2
Subtract 2 g^3 - 5 g^2 from both sides:
6 g^3 + 3 g^2 = 0
Factor g^2 and constant terms from the left hand side:
3 g^2 (2 g + 1) = 0
Divide both sides by 3:
g^2 (2 g + 1) = 0
Split into two equations:
g^2 = 0 or 2 g + 1 = 0
Take the square root of both sides:
g = 0 or 2 g + 1 = 0
Subtract 1 from both sides:
g = 0 or 2 g = -1
Divide both sides by 2:
Answer: g = 0 or g = -1/2
