Find the interquartile range (IQR) of the data in the dot plot below

Mathematics
1 answer:
Nonamiya [84]3 years ago
3 0

Answer:

2 cm

Step-by-step explanation:

As we know, the iqr is found by subtracting Q3-Q1. So that means we need to find them first. Finding the median will help us accomplish this task. So when writing out the numbers to solve it 81,82,83,83,84,84,84,85 because the amount of data points are an even number, we will have two data points which will help us solve our median which in this case is where the 83 and 84 meet. Our median is thus 83+84/2 which is 83.5. Now look on both sides of the two numbers which make up our median. On either side of the 2 data points needed for the median, the is another 3 data points. To find your q1 and q3, you need to find the median of these numbers. For Q1 look for the median between the numbers 81,82,83 and for Q3, look for the median in the numbers 84,84,85. So, knowing this information, our Q1 value is 82 and our Q3 value is 84. So..... input these into the equation we have up top which is Q3-Q1=IQR so...... 84-82=IQR, thus, our IQR is 2.

BRAINLIEST!!! I need help ASAP how do I find the percent change from 1960 to 2000
SVEN [57.7K]

Answer:

percentage change  from 1960 to 1970 =( 0.11 ÷0.25 ) × 100

                                 = 44 %  

Percentage change from 1970 to 1980 =( 0.83 ÷ 0.36) × 100

                                                                 = 230.55%

 percentage change from 1980 to 1990 = ( 0.16 ÷ 1.19) × 100

                                               = 13.44%

percentage change from 1990 to 2000 = (- 0.09 ÷ 1.35) × 100

                                             = -6.667%                                              

Step-by-step explanation:

Item : 1960      1970          1980           1990             2000

gallon: $0.25  $0.36        $1.19    $1.35                 $1.26

change : 0.36 - 0.25 = 0.11

percentage change  from 1960 to 1970 =( 0.11 ÷0.25 ) × 100

                                 = 44 %

 Percentage change from 1970 to 1980 =( 0.83 ÷ 0.36) × 100

                                                                 = 230.55%

 percentage change from 1980 to 1990 = ( 0.16 ÷ 1.19) × 100

                                               = 13.44%

percentage change from 1990 to 2000 = (- 0.09 ÷ 1.35) × 100

                                             = -6.667%

Let AB = 24, AC = 10 and BC = 26.
nata0808 [166]

Answer:

a) 24

b) 10

c) 12/13

d) 5/13

e) 12/5

Step-by-step explanation:

a) We can see that the leg opposite <C is AB, and we are given AB = 24

b) We can see the leg adjacent to <C is AC, and we are given that AC = 10

c) The trig function sine is equal to

\frac{opposite}{hypotenuse}

The opposite, AB, is 24, and the hypotenuse, BC, is 26. We can plug those numbers in:

sin(c) = \frac{24}{26} = \frac{12}{13}

d)The trig function cosine is equal to

\frac{adjacent}{hypotenuse}

The adjacent, AC, is 10, and the hypotenuse, BC, is 26. We can plug those numbers in:

cos(c) = \frac{10}{26} = \frac{5}{13}

d)The trig function tangent is equal to

\frac{opposite}{adjacent}

The opposite, AB, is 24, and the adjacent, AC, is 10. We can plug those numbers in:

tan(c) = \frac{24}{10} = \frac{12}{5}

F(x)= x squared -3x + 2 divided by 3x squared + 9 x -12
VashaNatasha [74]

Answer:

=(x-2)/3(x+4)

Step-by-step explanation:

F(x)=x²-3x+2/3x²+9x-12

Using mid term break formula

=x²-2x-x+2/3(x²+3x-4)

=x(x-2)-1(x-2)/3(x²+4x-x-4)

=(x-2)(x-1)/3{x(x+4)-1(x+4)}

=(x-2)(x-1)/3(x-1)(x+4)

Cancelling (x-1)

We get

=(x-2)/3(x+4)

Hope it helps :)
