Is 64 cups bigger than 30 pints
sattari [20]
Hello!

Yes indeed,

It is Bigger than 30 Pints, Why?

Well because 1st we have to remember that 1 cup = 0.5 pints, which is like 1/2 
And also, remember that if there were 30 pints, then that would = to 60 cups, but in this case we get 64, which of course is seen bigger because of 4 cups more.

So yes as i said in the beginning, 64 IS bigger than 30 Pints because if it were equal, it would then have to be 60 Cups instead of 64.

Hope this Helps! Have A Wonderful Day! :)

For one month Siera calculated her home town’s average high temperature in degrees Fahrenheit. She wants to convert that tempera
DaniilM [7]

Answer:

Option A) The temperature of F degrees Fahrenheit converted to degrees Celsius

Step-by-step explanation:

The formula to convert temperature from degrees Fahrenheit to degrees Celsius is:

C(F)=\frac{5}{9}(F-32)

If we have the measure of temperature in degrees Fahrenheit we can convert that temperature to degrees Celsius by substituting it in place of F. For example, if we want to convert 50 degrees Fahrenheit to degrees Celsius just  replace F in the above formula by 50 and C(F) will give the equivalent temperature in degrees Celsius.

So, C(F) represents the temperature of F degrees Fahrenheit converted to degrees Celsius. Option A gives the correct answer.

Three airlines serve a small town in Ohio. Airline A has 48% of all scheduled flights, airline B has 26% and airline C has the r
kozerog [31]

Answer:

0.5969 = 59.69% probability that it was a flight of airline A

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Left on time.

Event B: From airline A.

Probability of a flight leaving on time:

81% of 48%(airline A).

61% of 26%(airline B)

40% of 26%(airline C). So

P(A) = 0.81*0.48 + 0.61*0.26 + 0.40*0.26 = 0.6514

Probability of leaving on time and being from airline A:

81% of 48%. So

P(A \cap B) = 0.81*0.48 = 0.3888

What is the probability that it was a flight of airline A?

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.3888}{0.6514} = 0.5969

0.5969 = 59.69% probability that it was a flight of airline A
