A train left for Houston, and 7 hours later, a car traveling 62 mph tried catching up to the train. After 4 hours, the car caugh

lana [24]

Answer: 22.55 mph

Step-by-step explanation:

Let the speed of the train be n

4 × 62 = 248 which is the distance travelled by the car in 4 hours and the train travelled in 11 hours

11 × n = 248

11n = 248

n = 248/11

n = 22.55mph

The numbers 5, 6, 7, and 8 are randomly arranged to create a four-digit number. What is the probability that the number formed i

myrzilka [38]

Using the arrangements and the probability concept, it is found that there is a 0.75 = 75% probability that the number formed is not divisible by 4.

A probability is the number of desired outcomes divided by the number of total outcomes.

The number of possible arrangements of n elements is given by $A_n = n!$

In this problem, there are 4 elements, hence $n = 4, T = A_4 = 4! = 24$ .

A number is a multiple of 4 if the number composed by it's last 2 digits are multiples of 4.

Hence, the possible options for the last 2 digits are: 56, 68, 76.

For each of them, there are $A_2 = 2! = 2$ options for the first 2 digits, hence, there will be 2 x 3 = 6 multiples of 4.

The other 18 numbers formed are not divisible by 4, hence:

$p = \frac{18}{24} = 0.75$

0.75 = 75% probability that the number formed is not divisible by 4.
