The stem-and-leaf plot shows the scores of a class of sixth graders on a math test.
SOVA2 [1]

A stem and leaf plot shows sets of two digit numbers, by separating the ten’s place and the one’s place. On the left is the different ten’s values, while on the right next to each of the values on the left is the one’s values that associate with each of the ten’s values. This means that the numbers in this set of data are 32, 47, 51, 55, 55, 55, 58, 64, and so on. From there, you can use that knowledge to figure out how many scores were above 60.


The terms that are above 60 are 64, 65, 73, 74, 77, 87, 88, 91, 93, 93, 97, 99, and 99, for a total of 13 of the 20 scores being above 60.

The graph of the piecewise function f(x) is shown what is the domain of f(x)
Rom4ik [11]

The domain of a function is where we have a value for x.

Since that's the case the domain of f(x) = {x e R / 1 ≤ x < 5}

We see that we have a value for x = 1 cuz we have a filled circle, but we don't have a value for x = 5, look at the unfilled circle

So, our x can vary between 1 and 5, but can't be 5.

Scott Harris can invest $7,000 in a 1-year CD that earns interest at an annual rate of 4 percent compounded monthly. The amount
Tom [10]

Answer:

option A  is answer.

Step-by-step explanation:

Amount of interest earned for compounded monthly  for $1 = 1.040742

Amount of interest earned for compounded quarterly for $1= 1.040604

Difference for $1  =   1.040742 - 1.40604

                 =0.000138

Difference for $7000 = $7000x0.000138

                                    = 0.966

                                      or $0.96
