Find an equation for the nth term of the arithmetic sequence.
a19 = -58, a21 = -164

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

345

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
