Answer:

634

Step-by-step explanation:

Nth term of an arithmetic progression is given by:

Tn=a+(n-1)d

Where 'Tn' is the Nth term of A.P. , 'a' is the first term of A.P. , 'n' is the no. of terms and 'd' is the common difference.

22-13=9, 31-22=9, 40-31=9.

So, d=9

a=13

n=70

Put the values in the Formula.

T70=13+(70-1)*9=13+69*9=13+621=634

If SAT scores are normally distributed with a mean of 1518 and a standard deviation of 325, find the probability that a randomly

aliya0001 [1]

Mean, x_bar = 1518
Standard deviation, sigma = 325
Range required: 1550 ≤ X ≤ 1575

Z = (X - x_bar)/sigma

Z1 = (1550-1518)/325 ≈ 0.1
Z2 = (1575-1518)/325 ≈ 0.18

From Z tables,
P(Z1) = 0.5398
P(Z2) = 0.5714

P(1550≤X≤1575) = P(Z2) - P(Z1) = 0.5714 - 0.5398 = 0.0316

The correct answer is C.

• The domain are real numbers

• And the range is approximately from -2 to 2

The maximum value of r on the graph is 2

• Yes the graph is continuous and it is bounded above and below

• The graph is symmetrical about the x axis and not about the y axis.

• No asymptotes
