A race is 7/10 kilometers long. Maya ran 9 of these races. How far did she run altogether? Write your answer in simplest form.

1 answer:

8 0

Answer:

She ran

$6 \frac{3}{10} km \: or \: 6.3 \: km$

Step-by-step explanation:

To find the answer you multiply the amount of races (9) by the length of each race (7/10 km).

$\frac{7}{10} \times \frac{9}{1} = \frac{63}{10} \: or \: 6 \frac{3}{10}$

Your answer would be 600 centimeters. If you look at a ruler you'll see that there are centimeters and no meters because you'll need 100 cm.

Using the definition of expected value, it is found that Ayo can be expected to make a profit of £55.8.

The expected value is given by the sum of each outcome multiplied by it's respective probability.

In this problem:

The player wins $6, that is, Ayo loses £6, if he rolls a 6 and spins a 1, hence the probability is $\frac{1}{6} \times \frac{1}{12} = \frac{1}{72}$ .

The player wins $3, that is, Ayo loses £3, if he rolls a 3 on at least one of the spinner or the dice, hence, considering three cases(both and either the spinner of the dice), the probability is $\frac{1}{6} \times \frac{1}{12} + \frac{1}{6} \times \frac{11}{12} + \frac{5}{6} \times \frac{1}{12} = \frac{1 + 11 + 5}{72} = \frac{17}{72}$
