Answer:
yes
Step-by-step explanation:
6 is half of 12. 15 is half of 30. The ratios are equal, so the fractions are proportional.
Answer: yes
Also, you can reduce both fractions.
Divide the numerator and denominator of 6/12 by 6 to get 1/2.
Divide the numerator and denominator of 15/30 by 15 to get 1/2.
Since both fractions reduce to 1/2, 6/12 and 15/30 are equivalent fractions and are proportional.
Answer:

And replacing using the mass function we got:
And adding the values we got:

Step-by-step explanation:
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We want to find the following probability:

And replacing using the mass function we got:
And adding the values we got:

Answer: 2 / 15
Step-by-step explanation:
3 red / 10 total
4 white / 9 total
3/10 * 4/9 = 12/90 = 2/15
1 figure = $17 so you multiply 4 and 17 to get 68
Martin will need to save $68
