Answer:

x\text{ hours}\cdot\frac{60\text{ minutes}}{\text{Hour}}=y\text{ minutes}

Step-by-step explanation:

We are asked to write a formula that converts x hours to y minutes.

We know that 1 hour equals 60 minutes.

\text{Number of hours}\cdot\frac{60\text{ minutes}}{\text{Hour}}=\text{Number of minutes}

Substitute the given values:

x\text{ hours}\cdot\frac{60\text{ minutes}}{\text{Hour}}=y\text{ minutes}

Therefore, the formula x\text{ hours}\cdot\frac{60\text{ minutes}}{\text{Hour}}=y\text{ minutes} can be used to convert x hours to y minutes.

3x = 67 - 22

3x = 45

x =  \frac{45}{3}

x = 15

A stack of one hundred fifty cards is placed next to a ruler, and the height of the stack is measured to be 5/8 inches.
DaniilM [7]
Divide 5/8 by 150, to see how thick each is, that'll give you 150 even pieces that add up to 5/8

\bf \cfrac{\frac{5}{8}}{150}\implies \cfrac{\frac{5}{8}}{\frac{150}{1}}\implies \cfrac{5}{8}\cdot \cfrac{1}{150}\implies \cfrac{1}{8\cdot 30}\implies \cfrac{1}{240}

A basketball player has made​ 70% of his foul shots during the season. If he shoots 3 foul shots in​ tonight's game, what is the
yulyashka [42]

Answer:

There is a 34.3% probability that he makes all of the​ shots.

Step-by-step explanation:

For each foul shot that he takes during the game, there are only two possible outcomes. Either he makes it, or he misses. This means that we use the binomial probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinatios of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

In this problem we have that:

n = 3, p = 0.7

What is the probability that he makes all of the​ shots?

This is P(X = 3).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 3) = C_{3,3}.(0.7)^{3}.(0.3)^{0} = 0.343

There is a 34.3% probability that he makes all of the​ shots.
