If two 6-sided dice are rolled what is the probability that both numbers will be even?

1 answer:

3 0

The probability of one dice rolling an even number is 1/2 as half the numbers are even. Since the events are independent, and there are 2 dice, we need to square 1/2 to get 1/4, assuming they are both fair dice

Answer:

Step-by-step explanation:

$\dfrac{x}{-12}=-0.4\qquad\text{multiply both sides by (-12)}\\\\-12\!\!\!\!\!\diagup^1\cdot\dfrac{x}{-12\!\!\!\!\!\diagup_1}=(-12)(-0.4)\\\\x=4.8$

Answer:

$Average\ Speed = 60 mi/hr$

Step-by-step explanation:

Given

$Distance = 345\ miles$

$Time = 5\ hours\ 45\ minutes$

Required

Determine the average speed

This is calculated as thus:

$Average\ Speed = \frac{Distance}{Time}$

Convert time to hour:

$Time = 5\ hours\ 45\ minutes$

$Time = 5\ hours + \frac{45}{60}\ hour$

$Time = 5\ hours + \frac{3}{4}\ hour$

$Time = \frac{20 + 3}{4}\ hours$

$Time = \frac{23}{4}\ hours$

$Time = 5.75\ hours$

$Average\ Speed = \frac{Distance}{Time}$

$Average\ Speed = \frac{345}{5.75}$

$Average\ Speed = 60 mi/hr$

A mule deer can run one over four of a mile in 25 seconds. At this rate, which expression can be used to determine how fast a mu

geniusboy [140]

Speed (v) = distance (d) / time (t)
so either the second or third. if this is realistic deer can't run 100 miles per hour so is say the second initially but to check what is .25miles/25s convert to hours. (3600 seconds in an hour) so .25*3600=900 then 900miles/25hour= 36miles/ hour.
