Kyle saves 8% of his income for a new car this year his salary was $2000 less than in the previous year and he saved $3000 what

Annette [7]

First let us calculate for his salary this year. We know that 3000 is only 8% of his salary, hence:

0.08 * salary = 3000

salary = 3000 / 0.08

salary = 37,500

Therefore his previous salary is:

previous salary = 37,500 + 2,000

previous salary = $39,500

Four different digits from 1 to 9 are required to open a safe.

masha68 [24]

Answer: 5942

Step-by-step explanation:

Clue 4 states exactly two of the digits = 1, 4, or 9

Clue 1 leaves us with the following combinations:

1, 9, 2, 8

1, 9, 3, 7 eliminate by clue 5

4, 9, 2, 5

1, 4, 7, 8

Clue 5 directs us to the following order for 1,9,2,8

2 __ __ 1 --> 2981 or 2891 eliminate by clue 2

9 __ __ 8 --> 9128 or 9218 eliminate by clue 6

9 __ __ 2 --> 9182 or 9812 eliminate by clue 6

Clue 5 directs us to the following order for 4,9,2,5

5 __ __ 2 --> 5492 or 5942 eliminate 5492 by clue 2

9 __ __ 2 --> 9452 or 9542 eliminate by clue 3

Clue 5 directs us to the following order for 1,4,7,8

4 __ __ 1 --> 4781 or 4871 eliminate by clue 2

The only combination not eliminated is 5-9-4-2, which satisfies all six clues.

1) 5 + 9 + 4 + 2 = 20

2) 5 > 4

3) 9 - 2 > 5

4) 4 & 9 but not 1 are included

5) 5 + 2 = 7, which is a prime number

6) 2 < 5, 9, 4

Calculate the mean of each data set below. Can you find any shortcuts that allow you to find the mean without having to do much calculation? Homework help 6, 10, 6, 10 11, 12, 12, 13, 12 0, 5, 4, 8, 0, 7

Answer: To find the mean of the given observations. we just need to first find the sum of the given observations and the divide the calculate sum by the total number of observations.

So here:

Sum of of observations $=6+ 10+ 6+10+11+12+12+13+12+0+ 5+ 4+ 8+ 0+7=116$

Number of observations = 15

Therefore, the mean $=\frac{116}{15}= 7.733$
