Answer:

Step-by-step explanation:

Sometimes.  If the decimal never repeats itself and never ends, like pi, it is irrational.  But if the decimal is .5 or .333333333333333... it either terminates (ends) or repeats itself forever, making it rational.

You practice your basketball shots every day. On Friday you made 20 shots. On Saturday you made 16 shots. What is the percent de
STatiana [176]
So,

All you have to do to find the percent decrease is to subtract your score on Saturday from your score on Friday and divide the result by your score on Friday.  If you let "f" represent your score on Friday and let "s" represent your score on Saturday, you can re-write this mathematically:

\frac{f - s}{f} = percent\ decrease

Substitute.
\frac{20 - 16}{20} = percent\ decrease
\frac{4}{20} \ or\  \frac{1}{5}\ or\ twenty\ percent = percent\ decrease

The percent decrease in shots you made was 20%.  That would be option C.

1.- What type of parabola is this?
xz_007 [3.2K]

Answer:

<u>Part 1</u>

<u>Sideways or "horizontal" parabola</u> with a horizontal axis of symmetry.

<u>Part 2</u>

The vertex is the turning point:  (-3, 1)

<u>Part 3</u>

Vertex form of a horizontal parabola:

x=a(y-k)^2+h    

where:

  • (h, k) is the vertex
  • a is some constant
    If a > 0 the parabola opens to the right.
    If a < 0 the parabola opens to the left.

Point on the curve:  (-1, 2)

Substituting the vertex and the found point into the formula and solving for a:

\implies -1=a(2-1)^2-3

\implies -1=a-3

\implies a=2

<u>Part 4</u>

Equation for the given parabola in vertex form:

x=2(y-1)^2-3

Equation in standard form:

x=2y^2-4y-1

What is the difference between the mean and the median of the data set?<br> (22, 8, 10, 18, 12, 20)
IgorC [24]

Let D = difference between mean and median of data.

Mean = (22 + 8 + 10 + 18 + 12 + 20)/6

Mean = 90/6

Mean = 15

Let m = median

m = 8, 10, 12, 18, 20, 22

m = (12 + 18)/2

m = 30/2

m = 15

D = M - m

D = 15n- 15

D = 0
