Answer:
55+19.50m=250
Step-by-step explanation:
55 is the intial fee it doesn't have to be multiplied by anything.
19.50 is monthly it is multiplied by how many months she is going to be there. the amount of months is unknown so you use a variable I chose m for months or monthly.
it will be set equal to 250 because that is the amount of money that she has to spend.
I hope this helps I am sorry if it is wrong
Answer:
probability that he or she will answer at least 4 problems correctly = 0.5
Step-by-step explanation:
probability that he or she will answer at least 4 problems correctly is given as;
P (at least 4 correctly) = P (exactly 4 correctly) + P (all 5 correctly)
Since there are 10 problems. 4 is from the 7 problems chosen and 1 is from the 3 problems we can't figure out. Thus, P(exactly 4 correctly) = 7C4 x 3C1
Thus, P (at least 4 correctly) = [ (7C4) x (3C1) ] / (10C5)] + [(7C5)/(10C5)]
= [(35 x3)/252 ] + [21/252]
= [ 105/252 ] + [ 21/252 ]
= 126 / 252
= 0.5
The general term of an arithmetic sequence is
an = a1 +(n-1)d
Your sequence has first term a1 = 11 and common difference d = 4. Then the general term is
an = 11 + (n-1)*4
The simplest form of the general term is
an = 7 + 4n
