an expression is shown: 8^2/(-4)^2+(-1/2) x 2^3 group of answer choices 64/-8 + 6/-2 -11 64/16 +8/-2 0

Answer:

Step-by-step explanation:

To simplify the given expression, let's follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.

First, we have exponents:

8^2 = 8 * 8 = 64

(-4)^2 = -4 * -4 = 16

2^3 = 2 * 2 * 2 = 8

Next, let's evaluate the multiplication:

(-1/2) x 2^3 = (-1/2) x 8 = -4

Now, we can perform the division:

8^2 / (-4)^2 = 64 / 16 = 4

Finally, let's simplify the expression by performing the remaining additions and subtractions:

4 + (-4) = 0

Therefore, the correct answer is 0.

An airplane flies in a straight line for 5 hours & then takes a turn 12 degrees to the right & flies 3 hours in the new direction. The plane maintained a constant speed of 550 miles per hour throughout the flight. How far is the plane from the starting point in the air at the end of this time? (could someone pls explain this lol -3-)

Answers

we have triangle with side 5*550 = 2750 and side 3*550=1650 and angle 180-12 = 168 between them
Now we use the cosine theorem to get third side

$d = √(2750 ^2+1650^2-2*1650*2750*cos(168)) = 4 377.40670603041$

Here are the possible outcomes when a pair of fair dice is rolled.1 2 3 4 5 6

4 5 6 7 8 9 10
5 6 7 8 9 10 11
6 7 8 9 10 11 12

In a roll of a pair of fair dice, what is the probability of the outcome being either a multiple of 3 or an even number? Are these events mutually exclusive?

Answers

I don't understand the big table of numbers at the top at all,
and don't see how it relates to the question.

There are 36 possible outcomes for the roll of a pair of dice.
According to your specifications, the successes are:

-- Multiples of 3:
   1 ... 2 (3)
   2 ... 1
   3 ... 3 (6)
   1 ... 5
   5 ... 1
   2 ... 4
   4 ... 2
   3 ... 6 (9)
   6 ... 3
   4 ... 5
   5 ... 4
   6 ... 6 (12)
(12 different outcomes)

-- Even numbers:
   1 ... 1 (2)
   1 ... 3 (4)
   3 ... 1
   2 ... 2
   3 ... 3 (6)
   1 ... 5
   5 ... 1
   2 ... 4
   4 ... 2
   2 ... 6 (8)
   6 ... 2
   3 ... 5
   5 ... 3
   4 ... 4
   4 ... 6 (10)
   6 ... 4
   5 ... 5
   6 ... 6    (12)
(18 different outcomes)

The events are NOT mutually exclusive.
A roll of 6 (5 ways) or 12 (1 way) meets both requirements.

Successful outcomes:
Multiples of 3 . . . . 12
Even numbers . . . 18
       Duplicates . . . . 6

So there are 24 different successful outcomes.

Probability = (24) / (36) = 2/3 = (66 and 2/3) %
