When you roll two numbers you have four kinds of outcomes: EE, EO, OE, OO (where E = even, O = odd).

You get an even sum only if you sum two numbers that are both even or both odd, therefore the outcomes wanted are two: EE and OO.

Therefore:
P(sum is even) = 2 / 4 = 0.5

Hence, there is a 50% probability that, when you roll two numbers, their sum will be even.

What is the area of the figure below

jek_recluse [69]

Answer:

Option A

Step-by-step explanation:

Area of the composite figure = Area of ΔABH + Area of BCGH + Area of ΔDEF

Area of ΔABH = $\frac{1}{2}(\text{Base})(\text{Height})$

= $\frac{1}{2}(6)(8-5)$

= 9 in²

Area of the trapezoid = $\frac{1}{2}(CG+BH)(\text{Distance between these lines})$

= $\frac{1}{2}(6+4)(5)$

= 25 in²

Area of ΔDEF = $\frac{1}{2}(8)(6)$

= 24 in²

Therefore, area of the given figure = 9 + 25 + 24

= 58 in²

Option A will be the correct option.

Fractions are equivalent to 9/8

astraxan [27]

Answer:

9/8, 18/16, 27/24, 36/32, 45/40, 54/48, 63/56, 72/64, 81/72, 90/80, and so on ...

Explanation:

Two fractions are equivalent when they are both equal when written in lowest terms. The fraction 18/16 is equal to 9/8 when reduced to lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (9/8) by the same integer number, ie, multiply by 2, 3, 4, 5, 6 ...

18/16 is equivalent to 9/8 once 9 x 2 = 18 and 8 x 2 = 16

27/24 is equivalent to 9/8 once 9 x 3 = 27 and 8 x 3 = 24

36/32 is equivalent to 9/8 once 9 x 4 = 36 and 8 x 4 = 32
