If y varies directly as x and y = 12 when x = 8, find y when x = 14.

1 answer:

8 0

The direct variation between x and y may be written as,
y = kx
where k is the constant of variation. From the first set of values of the variables,
12 = k(8)
the value of k is 1.5. Substituting the next set to the same equation,
y = 1.5(14)
The value of y is 21.

Answer:

Yes, Emily is correct.

Step-by-step explanation:

If you have a - sign in front of a number in parenthesis that is negative, then what you are doing is taking the opposite of that negative number. Remember that the opposite of a negative number is a positive number. In this case, we want the opposite of negative five. What is that? It is +45, or 45. So yes, Emily is correct.

Answer:

25 mph, 5 mph

Step-by-step explanation:

Speed of the boat = x
Speed of the current = y

Travel downstream, speed is:

x + y = 120/4 = 30

Travel upstream, speed is:

x - y = 120/6 = 20

Add up the equations:

x + y + x - y = 30 + 20
2x = 50
x = 25

Find y:

y = 25 - 20 = 5

Speed of the boat is 25 mph

Speed of the current is 5 mph

In a binomial experiement, what does it mean to say that each trial is independent of the other trials?.

In-s [12.5K]

In a binomial experiment to say that each trial is independent of the other trials means that the outcome of one trial does not affect the other trial.

An experiment with a set number of independent trials and just two results is referred to as a binomial experiment.

To say that in a binomial experiment, each trial is independent of the other trials means that the outcome of one trial does not affect the other trials.

This means that whatever we get in the first trial, does not affect the outcome of the second or any other trial.

For example, in the tossing of a coin 10 times, the outcome of the first trial doesn't affect any of the other nine trials.
