Answer:

I'll help you out. Question: Are you solving for A or for N?

If you're solving for N: Isolate the variable by dividing each side by factors that don't contain the variable. n = A/10 - 7/10

Micheal has a set of 5 cards shown below. Micheal wil randomly select a card, not replace it, then select another card. What is

strojnjashka [21]

Answer:

3/20 or 15%

Step-by-step explanation:

Out of 1,2,3,4, and 5, there are 3 prime numbers. This makes the odds of selecting one of those prime numbers 3/5. Then, saying that he does pick a prime number and discards that card, there are now four cards, one of them being the number one. His chances of selecting this card is 1/4.

To find the probability you need to multiply the two probabilities together.

3/5 times 1/4 is 3/20.

So your answer is 3/20 or 15%.

How do i turn 44.4% as a ratio?

SIZIF [17.4K]

$a=44.4\%x\\b=(100\%-44.4\%)x=55.6\%x\\ \\ \frac{a}{b} = \frac{44.4\%x}{55.6\%x} = \frac{44.4}{55.6} = \frac{444}{556} = \frac{111\cdot4}{139\cdot4}= \frac{111}{139}$
