Answer to the nearest tenth is 20.8
Answer:
B. 4/21
Step-by-step explanation:
⇒This question is on probability
⇒Number of boys=3
⇒Number of girls=4
⇒P(S)= 4+3=7
Probability for a girl to win is= 4/7
We have 3 awards a free movie ticket, a collectible poster, or a free popcorn
P(S)= 3
Probability of being awarded a free popcorn = 1/3
The probability that a girl will win free popcorn =
4/7 * 1/3 = 4/21
hope i helped and have a wonderful day
Step-by-step explanation:
Use Newton's second law. Force equals mass times acceleration.
F = ma
300 N = (100 kg) a
a = 3 m/s²

Answer:
A linear equation can have no, one or infinite solutions.
Step-by-step explanation:
No Solution:
Consider the equation 8x - 19 = 8x + 19
Subtract 8x from both the sides. We get:
8x - 8x - 19 = 8x - 8x + 19
⇒ - 19 = 19
This is absurd. So, this system of equations has no solution.
One Solution:
For the equation 9x + 5 = 14
⇒ 9x = 9
⇒ x = 1 the only solution to the equation.
Infinite Solutions:
The solution to the equation 3x = 3x are infinite.
Whatever the value of x the equation always remains the same. So, we have infinite values of x that can satisfy the equation.
