Answer: 2, 9, 14, 17, 19

Step-by-step explanation:

A box plot uses the values: minimum, maximum, median, first quartile and third quartile.

First sort the data from lowest to highest.

2,8,9,11,14,15,17,19,20

Thus, the minimum, or Data Point 1 is 2.

Then find the median.

8,9,11,14,15,17,19

9,11,14,15,17

11,14,15

Thus, the median, or Data Point 3 is 14.

For the 1st and 3rd quartile, simply, ignoring the median, find the median of the first and second half of the data.

8,9,11

Thus, the first quartile, or Data Point 2 is 9.

15,17,19

17.

Thus, the third quartile, or Data Point 4 is 17.

The maximum of the data, or Data Point 5 is 19.

Choose all statements that accurately describe properties of parallel and perpendicular lines.

KatRina [158]

Incomplete question. I inferred you want to know the properties of parallel and perpendicular lines. Which I provided below.

Explanation:

In geometry, parallel lines are two lines that are always drawn at the same distance apart and never touch each other. Parallel lines are usually denoted by the symbol ∥.

Here are some of their properties;

When a transversal intersects two parallel lines:

usually, the corresponding angles of the lines are equal.
vertically opposite angles are equal.
the alternate exterior angles are equal.

Perpendicular lines are two lines that meet at a right angle (90 degrees) to each other.

Properties: two lines that meet, implies all four angles are right angles.

in a recent survey 34% spoke another language. If 413 students participated in the survey about how many students is this

Bad White [126]

Answer=About 140 students spoke another language

34%=34/100=0.34

413*0.34=140.42 students spoke another language

since we can't have .42 of a student, lets round to the nearest whole number...

About 140 students spoke another language

The range of the function y=secx-2 is all reals except -1 1 -3 -2

Umnica [9.8K]

Answer:

For a function y = f(x), the range is the set of all the possible values of y.

In the question you wrote:

y = secx - 2

This can be interpreted as:

y = sec(x - 2)

y = sec(x) - 2

So let's see each case (these are kinda the same)

If the function is:

y = sec(x - 2)

Firs remember that:

sec(x) = 1/cos(x)

then we can rewrite:

y = 1/cos(x - 2)

notice that the function cos(x) has the range -1 ≤ y ≤ 1

Then for the two extremes we have:

y = 1/1 = 1

y = 1/-1 = -1

Notice that for:

y = 1/cos(x - 2)

y can never be in the range -1 < x < 1

As the denominator cant be larger, in absolute value, than 1.

Then we can conclude that the range is all reals except the interval:

-1 < y < 1

If instead the function was:

y = sec(x) - 2

y = 1/cos(x) - 2

Then with the same reasoning, the range will be the set of all real values except:

-1 - 2 < y < 1 - 2

-3 < y < -1
