Answer:

The proportion is \frac{41}{100} = 0.41 or 41%

Step-by-step explanation:

Hello!

The expected proportion is calculated as "the number the event of interest has occurred"(i.e. success) divided the total of trials.

In this case, your success is the number of times your friend guessed a card correctly in 100 trials.

The proportion is \frac{41}{100} = 0.41 or 41%

I hope it helps!

A kilogram of seawater contains 1/40 kg of salt. How much salt is there in two buckets of seawater, which contain 500 liters of
never [62]

Two buckets of seawater contain 13\frac{28}{40} kg of salt.

Step-by-step explanation:

Amount of salt in 1 kg water = \frac{1}{40}\ kg

It is given that;

1 liter = 1\frac{12}{125} = \frac{137}{125}\ kg

500 liters = 500*\frac{137}{125} = \frac{68500}{125}

500 liters = 548 kilogram

As,

1 kg of seawater = \frac{1}{40}\ kg of salt

548 kilograms = \frac{1}{40}*548

548 kilograms = 13\frac{28}{40} kilograms of salt

Two buckets of seawater contain 13\frac{28}{40} kg of salt.
