Answer: 23.2
Step-by-step explanation:
Answer:
5 and 9/14
Step-by-step explanation:
convert the numbers into improper fractions
8/7 + 9/2
=
(8 × 2) + (9 × 7)
7 × 2
=
79/14 or 5 and 9/14
Pr[X > 2] corresponds to the area under the graph of P(x) for 2 ≤ x ≤ 8, which is a rectangle with base 8 - 2 = 6 and height 0.125. So
Pr[X > 2] = 6 • 0.125 = 0.750
Step by step:
3 x 9/10
Turn 3 into a fraction
3/1 x 9/10
Now multiply straight across
3x9=27 and 1x10=10
So you get
27/10 or 27/10 or 2.7
This can also be completed by simply turning 9/10 into a decimal and doing
3 x 0.9 = 2.7
