Answer: 8.7 years

Step-by-step explanation:

The average number of hours that a cat sleeps in a day is 16. The average cat lives 13 years.

We would determine the total number of hours that the average cat lives.

Assuming that there are 365 days in a year, it means that the number of days that an average cat lives would be

365 × 13 = 4745 days

There are 24 hours in a day, this means that the number of hour that a average cat lives would be

24 × 4745 = 113880 hours

If the cat sleeps

16 hours in 24 hours,

In 113880 hours, the cat would sleep

(16 × 113888)/16 = 75920 hours.

Converting 75920 hours to years, it becomes

75920/24 × 365 = 8.7 years

What value of g makes the equation true?<br><br> (x+7)(x-4)=x²+gx-28
34kurt

Answer:

g = 3

Step-by-step explanation:

(x+7)(x-4) = x²+ gx -28

Multiply the two parenthesis

(x+7)(x-4)= x² -4x +7x -28

Combine like terms

(x+7)(x-4)= x²+3x-28

Compare the equations

x²+ gx -28 =  x² +3x -28

g = 3

50 % of 100 is what number
Sophie [7]
50% of 100 is 50. If you look at the percentage symbol, it has a line with two zeros. If you rearrange them it looks like a one hundred. 50%= .50= 1/2. 1/2 times 100=50

Solution: We are given the population mean =42

Now, in order to find which shift's mean is closest to population mean, we will find the mean of each shift.

The mean of shift 1 is:

Mean=\frac{18+25+56+42+29+38+54+47+35+30}{10}=\frac{374}{10}=37.4

The mean of shift 2 is:

Mean=\frac{23+19+50+49+67+34+30+59+40+33&#10;}{10}=\frac{404}{10}=40.4

The mean of shift 3 is:

Mean=\frac{19+22+24+40+45+29+33+29+39+59  }{10}=\frac{339}{10}=33.9

The mean of shift 4 is:

Mean=\frac{21+23+25+40+35+19+70+40+22+23  }{10}=\frac{318}{10}=31.8

We clearly see the mean of shift 2 is close to the population mean. Hence the option B) Shift 2 is correct.
