Answer:
28
Step-by-step explanation:
In a regular 52 card deck, 26 are black (clubs or spades). Additionally, there are two red jacks (diamonds and hearts). This equals 28/52. As a probability, it would be 28/52=14/26=7/13. This could also be expressed as a percentage or decimal. 0.538 or 53.8%. But the question asks <em>how many ways</em> can she choose a jack or black card, so I’m assuming they don’t want the probability, just the number, which is 28.
We have to write the standard form of : two hundred ten million, sixty four thousand , fifty.
210 * 10,000,000 + 64 * 10,000 + 50
Answer:
The standard form is 210,064,050.
Answer:
13 means the starting number
13 is the y-intercept (0,13)
For

, we have

and so

which is, again, only valid for

.
