What is the slope of a line perpendicular to ta line whose equation is y = -3/4x - 6
svp [43]

Answer:

4/3

Step-by-step explanation:

y = -3/4x - 6

m = -3/4

Slope of the line perpendicular to this line = -1/m

                                                                      = -1 ÷ (-3/4)

                                                                     = (-1)*\frac{4}{-3}\\\\=\frac{4}{3}

The lists below gives the donations, in dollars that two different charities received in 1 day. Compare the means of the two dat
icang [17]

Answer:

The mean of Planted Society's donations received is higher than Bees Park Expansion's.

Step-by-step explanation:

To get the mean, you want to add all of the numbers up and divide by how many numbers up. For example, you add all of the values for Planted Society and get 140. We know that there are 7 numbers given, so we do 140 divided by 7 to get a mean of 20. Same with Bees Park Expansion; add to get a total of 152. There are 8 numbers, and 152 divided by 8 is 19. This means 20>19. Mean is also written as average in questions.
