Answer:

200

Step-by-step explanation:

The nth term of an arithmetic sequence is given as:

f(n) = a + (n - 1)d

where a = first term

d = common difference

The first term of the sequence is 26 and the common difference is 2 (28 - 26 = 2)

The 88th term of the sequence is therefore:

f(88) = 26 + (88 - 1)*2

f(88) = 26 + (87 * 2)

f(88) = 26 + 174

f(88) = 200

The 88th term is 200.

Answer:

Mean = $\sum x P(x) = 36.86$

Standard deviation = $\sum x^2P(X)=1360.9$

Step-by-step explanation:

x P(x) $x \times P(x)$ $x^2 \times P(x)$

33 0.02 0.66 21.78

34 0.06 2.04 69.36

35 0.1 3.5 122.5

36 0.2 7.2 259.2

37 0.24 8.88 328.56

38 0.26 9.88 375.44

39 0.1 3.9 152.1

40 0.02 0.8 32

1 36.86 1360.9

We are supposed to find mean and standard deviation

Mean = $\sum x P(x) = 36.86$

Standard deviation = $\sum x^2P(X)=1360.9$

The sum of two numbers is 23. The difference of the numbers is 7.4. What are the two numbers?

Brums [2.3K]

X+y=23
X-y=7.4

X+y=23
y=23-X

X-y=7.4
(23-y)-y=7.4
23-2y=7.4
-2y=-15.6
Y=7.8

X+y=23
X+7.8=23
X=15.2

Therefore the two numbers are 7.8 & 15.2
