Nishi, who has a 70% free-throw percentage, is in a two-attempt free-throw situation. This means she will attempt the second free throw no matter what happens on the first. What is the probability of scoring zero points?

Answers

Nishi has a 70% chance of making a free-throw. This means that out of 100%, Nishi will miss the free-throw 30% of the time. 

Zero points means that Nishi will have to miss the free-throw twice. To calculate this occurrence, we must multiply the chances of Nishi missing twice.

This occurrence asks for a 30% chance to happen the first free throw, and a 30% chance to happen on the second free throw. Convert the percentages to a decimal:

30 / 100 = .30

Multiply these two occurrences together:

.30 * .30 = 0.09

Convert this decimal back into a percentage:

0.09 * 100 = 9

There is a 9% chance that Nishi will score zero points.

Answer:

9% that is your answer!

your employer has 600 business cards printed for you and you give away 280 of them to the nearest hundred what percent of the cards is left

Answers

First, find the number of cards that is left. 600 - 280 = 320.

Now find what percent of 600 320 is. This can be done like so:
(280)/(600) · 100%

This gives us 46.67 % (rounded to the nearest hundredth).

If a woman who has a mass of 115 lb, what is her mass in grams?

Answers

Answer:

Her mass is approximately 52,134.99 grams.

Step-by-step explanation:

To convert a mass from pounds (lb) to grams (g), you can use the following conversion factor:

1 lb = 453.59237 g

So, to find the mass of a woman who weighs 115 lb in grams:

Mass (in g) = 115 lb * 453.59237 g/lb = 52,134.98955 g

Therefore, her mass is approximately 52,134.99 grams.
