Jill can either only have 1 out of 5 toppings, 2 out of 5
toppings, until 5 out of 5 toppings. The total combinations would be:
total = 5C1 + 5C2 + 5C3 + 5C4 + 5C5
total = 31 combinations
So the probability that Jill will get just jalapenos and
spinach (1 combination) is:
<span>Probability = 1/31 = 0.03225 = 3.23%</span>
Answer:
you can maybe try asking desmos that app or web is very helpful it may help you with your question!
The expression of the ratio is 150:3
This is an arithmetic sequence because each term is 7 greater than the previous term, so 7 is what is called the common difference...
Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=first term, d=common difference, n=term number.
We know a=1 and d=7 so:
a(n)=1+7(n-1)
a(n)=1+7n-7
a(n)=7n-6
The above is the "rule" for the nth term.
Answer:
-2
Step-by-step explanation:
rise/run
But in this case, since you start by doing down, it would be negative.
