Daniel works for a pest control company and is spraying all the lawns in a neighborhood. Each lawn in a neighborhood is approxim
ankoles [38]

Answer:

252 minutes

Step-by-step explanation:

All lawns are the same size, so it doesn't matter the exact size of the each lawn. Ignore the 0.2 acre size.

He started the first house at 9:00 AM and the sixth house at 10:00 AM.

Read the sentence above carefully. He started the first lawn at 9:00 AM. Since he started the sixth lawn at 10:00 AM, that means he finished the fifth lawn at 10:00 AM. In 1 hour, from 9:00 AM to 10:00 AM, he did 5 lawns.

1 hour = 60 minutes

60 minutes per 5 lawns = 60/5 minutes/lawn

which can be reduced to

12 minutes per lawn

His unit rate is 12 minutes/lawn.

Now you multiply his unit rate by the number of lawns, 21 of them, to find the number of minutes to spray 21 lawns.

12 minutes/lawn * 21 lawns = 252 minutes

Answer: 252 minutes

The table shows the average number of hours of daylight per day for the last four months of the year. a 2-column table with 4 ro
mina [271]

The correlation coefficient for the data in the table is A. –0.993

<h3>Calculations and Parameters:</h3>

Using this formula: r = \frac{n(\sum xy)-(\sum x\sum y)}{\sqrt{n\sum x^2-(\sum x)^2}\sqrt{n\sum y^2-(\sum y)^2}}

We would use x and y to represent the unknowns.

n = 4

We have,

  • ∑x = 42,
  • ∑y = 44.37 ,
  • ∑xy = 461.3
  • ∑x^2 = 446,
  • ∑y^2 = 494

Putting these values in the formula r = \frac{n(\sum xy)-(\sum x\sum y)}{\sqrt{n\sum x^2-(\sum x)^2}\sqrt{n\sum y^2-(\sum y)^2}} would bring the answer as. A. –0.993
