f(x) = x^2 -3x +2

Replace x with 2:

f(2) = x^2 -3(2) +2

f(2) = 4-6 +2

f(2) = 0

g(x) = 4x-5

replace x with -1

g(-1) = 4(-1) -5

g(-1) = -4-5

g(-1) = -9

Now subtract

f(2) - g(-1) = 0 - (-9) = 0+9 = 9

The answer is 9.

The IQR is 42.5

Step-by-step explanation:

Interquartile range is the difference of third and first quartile.

First of all we have to find the median for that purpose the data has to be arranged in ascending order. The data is already in ascending order.

As the number of values are odd

n=21

The median will be: $(\frac{n+1}{2}) th\ term$

Putting n=21

$(\frac{21+1}{2})th\ term\\=(\frac{22}{2})th\ term\\= 11th\ term$

The 11th term is 133

So median = 133

Now the data is divided into two halves

One is: 98, 100, 101, 102, 108, 109, 111,118, 129, 132

2nd is: 135, 135, 145, 146, 146, 156, 170 176, 180, 180

Q1 will be the median of first half and Q3 will be the median of 2nd half.

As now the halves contain even number of values, the medians will be the average of middle two values

<u>For First Half:</u>

98, 100, 101, 102, <u>108, 109</u>, 111,118, 129, 132

$Q_1 = \frac{108+109}{2}\\Q_1 = \frac{217}{2}\\Q_1 = 108.5$

<u>For Second Half:</u>

135, 135, 145, 146, 146, 156, 170 176, 180, 180

$Q_2 = \frac{146+156}{2}\\Q_2 = \frac{302}{2}\\Q_2 = 151$

Now

<u>Interquartile Range:</u>

$IQR = Q_3-Q_1\\= 151-108.5\\=42.5$

Hence,

The IQR is 42.5

HURRY can a triangle can be constructed with angles measuring 115°,55°, and 20°? yes or no

EleoNora [17]

Answer:

no

Step-by-step explanation:

The sum of the angles of a triangle must add to 180 degrees

115+55+20 = 190

This is not equal to 180 so it is not a triangle.
