Answer:

 

B)  

55.5

Step-by-step explanation:The interquartile range is the third (upper) quartile of a data set minus the first (lower) quartile. Here, the median is 60, dividing the data set into a lower half below the median and an upper half above the median. Each of these halves contains four data values. The upper quartile is the number midway between 80 and 85, or 82.5. The lower quartile is the number midway between 19 and 35, or 27. The interquartile range is 82.5 - 27 = 55.5.

I need immediate help!! Picture is the question and my options
soldi70 [24.7K]

Answer:

a = -5.

Step-by-step explanation:

(3x + 2)(x + 1)

= 3x(x + 1) + 2(x + 1)

= 3x^2 + 3x + 2x + 2

= 3x^2 + 5x + 2

So the remainder a = 3x^2 + 5x - 3 - (3x^2 + 5x + 2)

= -3 - 2

= -3 - 2

= -5  (answer)

vagabundo [1.1K]
To find 5/6 of 12, you do 5/6 multiplied by 12

12*5/6 (first multiply 12 by 5 and leave the answer over 6)
60/6 (simplify)
The final answer is 10

Hope this helps!
