Answer:

median: 50, (IQR) interquartile range: 45

Step-by-step explanation:

Median: 50

Lower quartile: 20

Upper quartile: 65

interquartile range: 65 - 20 = 45

The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

What is x and the measurements?

nikitadnepr [17]

Answer:

see explanation

Step-by-step explanation:

The perimeter is the sum of the measures of the 3 sides.

Sum the sides and equate to 75, that is

2x - 9 + 3x + 4 + 2x + 3 = 75, that is

7x - 2 = 75 ( add 2 to both sides )

7x = 77 ( divide both sides by 7 )

x = 11

Thus

AB = 2x - 9 = 2(11) - 9 = 22 - 9 = 13 m

BC = 3x + 4 = 3(11) + 4 = 33 + 4 = 37 m

AC = 2x + 3 = 2(11) + 3 = 22 + 3 = 25 m

Is EFGH below a rectangle

poizon [28]

Answer:

D. No, because EFGH is a parallelogram but it’s diagonals are not congruent

Step-by-step explanation:

The differences between the end points of the diagonals are ...

F -H = (1, 1) -(2, -5) = (1 -2, 1 -(-5)) = (-1, 6)

G -E = (4, -2) -(-1, -2) = (4 -(-1), -2 -(-2)) = (5, 0)

The length of FH is more than 6, the length of GE is exactly 5. The diagonals are different length, so the figure cannot be a rectangle.

The midpoints of the diagonals will be in the same place if the sum of their end points is the same. (Dividing each sum by 2 gives the midpoint of that segment.)

F+H = (1, 1) +(2, -5) = (3, -4)

G+E = (4, -2) +(-1, -2) = (3, -4)

The diagonals bisect each other (have the same midpoint), so the figure is a parallelogram.

EFGH is a parallelogram, but not a rectangle: its diagonals are not congruent.

How many zeros does the function ????(x) = 3x^2 + 6x + 2 have? Explain how you know.

maxonik [38]

Answer:

The function has 2 zeros:

$x = -1 - \frac{1}{\sqrt{3}}\\x = -1 + \frac{1}{\sqrt{3}}$

Step-by-step explanation:

When you have a polynomial function, you can identify the grade of the function (the grade is the maximum potency) and this is the number of zeros that the function will have. In this case, you have a second-grade polynomial function that has 2 zeros.
