Answers

Answer 1
Answer:

For this case, the first thing we must take into account is the following rounding rules:

  • 1) If the decimal prior to the number to be rounded is greater than or equal to five, then the next number increases by one unit.
  • 2) If the decimal prior to the number to be rounded is less than five, then the next number remains the same.

We then have the following decimal:

34.287

Rounding to the nearest tenth of a minute we have:

34.3

Answer:

her race time to the nearest tenth of a minute is:

34.3

Max delivers 8,520 pieces of mail in one year. If he delivers the same number of pieces of mail each month, about how many pieces of mail does he deliver in 2 months? Explain your steps.Can you help me and explain this question... Thanks!

Answers

So there are 12 months in a year and he delivers 8,520 in that time. You must divide 8,520 by 12 which gives you how many he delivers in one month. 8,520/12=710. You are looking for two months so you should then multiply 710 by two giving you how much he delivers in 2 months.
710*2=1,420

What decimal is halfway between 18 hundredths and 3 tenths

Answers

The decimal halfway between 18 hundredths and 3 tenths is 0.24.

Given that, 18 hundredths and 3 tenths.

What are decimal numbers?

Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point. The dot present between the whole number and fractions part is called the decimal point.

Here, 18 hundredths

= 18/100

= 0.18

3 tenths

= 3/10

= 0.3

Now, halfway between 18 hundredths and 3 tenths

= (0.18+0.3)/2

= 0.24

Hence, the decimal halfway between 18 hundredths and 3 tenths is 0.24.

Lynn asked six friends how many cars their parents own. She recorded 1, 1, 2, 2, 2, and 4 cars. What is the mean absolute deviation of the number of cars? Round to the nearest tenth, if needed. A. 0.7 cars B. 1.1 cars C. 1.4 cars D. 2 cars

Answers

To find the mean absolute deviation, you have to find the mean first.
1+1+2+2+2+4=12
12 divided by 6 numbers=2         The mean of that is two
Next, you have to find the amount the original numbers are away from the mean.
1= 1 away from 2               2=0 away from 2               4=2 away from 2
You should get: 1,1,0,0,0,2              Next, you have to find the mean of the new set of numbers.    1+1+0+0+0+2=4
4 divided by 6= 2/3
The mean absolute deviation is 2/3

the anwser is a 0.7

What is the solution set to the equation x2 - 4x + 5 = 50?{-9, - 5}
{-9, 5)
{-5, 9}
{5, 9}

Answers

Answer:

B. {-9, 5}

Step-by-step explanation:

First, subtract 50 from both sides: x^2-4x-45=0

Factor: (x+9)(x-5)=0

Zero Product Property: x+9=0 and x-5=0, x=-9 and x=5

So the solution set is B
