Vincent flipped three coins during a probability experiment. The outcomes of the first 40 trials are shown in the table. Based on the information in the table, in how many of the next 120 trials will the outcome be exactly two of the coins showing heads?
Answer:
The number of next 120 trials will the result should be 48.
Step-by-step explanation:
The number of next 120 trials will the result should be 48.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Total trials = 40 trials.
The 2 heads and 1 tail should be 16 outcomes.
And, there are the next 120 trails.
So, the fraction will be
= 16/40
= 2/5
Now, the number of the next 120 trails should be
= 2/5 x 120
= 48
Hence, the number of the next 120 trials will result should be 48.

A cylinder with a height of 24 centimeters has a volume of 2,713 cubic centimeters.
Which is closest to the radius of the cylinder?
Answer:
I think you got it right
Step-by-step explanation:
The closest to the radius of the cylinder that has a volume of 2,713 cubic cm is: B. 6 cm.
What is the Volume of a Cylinder?Volume = πr²h
Given the following?
Radius (r) = ?
Height (h) = 24 cm
Volume of the cylinder = 2,713 cubic centimeters
2,713 = π(r²)(24)
2713/24π = r²
40 = r²
r = √40
r = 6.3 cm
The closest is: B. 6 cm.

ill give brainliest please answer right i need like 3 more questions
Answer:
I think I am right but it should be F/2 equals 4
Step-by-step explanation:
because you canceled out 9 so 9 is out of the equation
Answer:
f/2 = -20
f = -10
Step-by-step explanation:
1. Subtract 9 on both sides
f/2 + 9 -9 = 4 -9
= f/2 = -5
2. Multiply all terms by the same value to eliminate fraction denominators
2* f/2 = 2(-5)
3. Simplify
f = -10

On the scale model, the distance between the wheels on the left and the wheels on the right is inches. The state of Wyoming has old railroad tracks that are 4.5 feet apart. Can the modern train travel on those tracks?
Answer:
Step-by-step explanation:
No, modern train cannot travel on old railroad.
In rail transport, track gauge is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails.
Most of the modern train are based on broad gauge. The separation in broad gauge is about 5 ft and 6 inches and in the standard gauge the separation between the tracks is 4 ft and inches. So for the modern train it is not possible to travel on the tracks whose separation is no more than 4.5 feet.
Answer:
No, modern train cannot travel on old railroad.

Swim team members can race or dive. At a meet, 18 members race. The ratio of racers to divers is 6:2. How many meters are on the team? Show your work.
Plz help it due in 10 minutes.
Answer:
6 meters
Step-by-step explanation:
Set up a proportion as 18/x=6/2. The meters are unknown, so that's what the x value represents. Then, cross multiply (18 times 2 and 6 times x) to get 36=6x. By dividing both sides of the equation by 6, you'll get 6 meters as your answer.
