Answer:

13km

Step-by-step explanation:

Given data

Time= 8 days

Speed= 2 1/6 kilometers per day = 13/6 kilometers per day

Distance= ??

We know that

Speed= distance/time

therefore, Distance= speed*time

substitute

Distance= 13/6*8

Distance= 104/8

Distance= 13 km

Hence the crew did 13km

The energy magnitude M of an earthquake can be modeled by the equation
const2013 [10]

Answer: magnitude of an earthquake with an energy release of 7.079 X 10^26 =8

Step-by-step explanation:

Given that the magnitude M of an earthquake can be expressed by the equation

M=(2/3)log E - 9.9

Given that Energy release , E=7.079 X 10^26

Magnotude , M=(2/3)log E - 9.9

=2/3 log7.079 X 10^26 -9.9

2/3 x 2.8499719  -9.9

17.8999813 -9.9

=7.9999

rounded to 8 magnitude

Suppose you just purchased a digital music player and have put 15 tracks on it. After listening to them you decide that you like
blsea [12.9K]

Answer:

Total songs = 15

Liked songs = 3

Un liked songs = 15-3=12

Find the probability that among the first two songs played

​(a) You like both of them.

Probability that among the first two songs played you like both of them = \frac{3}{15} \times \frac{2}{14} = 0.029

​(b) You like neither of them.

Probability that among the first two songs played you like neither of them = \frac{12}{15} \times \frac{11}{14} = 0.629

​(c) You like exactly one of them.

Probability that among the first two songs played you like exactly one of them = \frac{3}{15} \times \frac{12}{14}+ \frac{12}{15} \times \frac{3}{14}= 0.343

(d) Redo​ (a)-(c) if a song can be replayed before all

​(a) You like both of them. Would this be​ unusual?

Probability that among the first two songs played you like both of them = \frac{3}{15} \times \frac{3}{15} = 0.04

​(b) You like neither of them.

Probability that among the first two songs played you like neither of them = \frac{12}{15} \times \frac{12}{15} = 0.64

​(c) You like exactly one of them.

Probability that among the first two songs played you like exactly one of them = \frac{3}{15} \times \frac{12}{15}+ \frac{12}{15} \times \frac{3}{15}= 0.32
