Answer:

Step-by-step explanation:

The given data set is:

27, 4, 54, 78, 27, 48, 79, 64, 5, 6, 41, 71

Firstly, arrange the given data set in ascending order, we get

4, 5, 6, 27, 27, 41, 48, 54, 64, 71, 78, 79

Now, the first half of the given data set is 4, 5, 6, 27, 27, 41 , thus the middle value is Lower quartile that is:

Lower quartile=\frac{6+27}{2}=\frac{33}{2}=16.5

And, the second half of the given data set is  48, 54, 64, 71, 78, 79, thusthe middle value is the upper quartile that is:

Upper quartile=\frac{64+71}{2}=\frac{135}{2}=67.5

Now, Interquartile range is given as:

IQR=Upper Quartile-Lower quartile

=67.5-16.5

=51.0

Thus, the Interquartile range is 51.

swat32

Answer:

  • x=1
  • y= -2

Step-by-step explanation:

  • 3x-2y =7
  • x+2y= -3
  • 4x=4
  • x=4/4
  • x=1
  • 3x-2y=7
  • 3(1)-2y=7
  • 3-2y=7
  • -2y=7-3
  • -2y=4
  • 2y=-4
  • y=-4/2
  • y= -2
  • Verify solution
  • x+2y= -3
  • 1+2y= -3
  • 2y=-3-1
  • 2y= -4
  • y= -4/2

Oliga [24]

Answer:

$41.16

Step-by-step explanation:

Length of bricks required = 35 feet, length of brick sold = 10 inches, cost of 10 inches brick = $0.98 per brick

Total number of brick required to build the back yard = Length of bricks required ÷ Length of brick sold

1 ft = 12 inches

Number of brick required = (35 * 12) ÷ 10

Number of bricks required = 42 bricks

Cost of brick required = Per length cost of brick * Number of bricks required

Cost of brick required = 0.98 * 42

Cost of brick required = $41.16

Ms. Fontanges would spend $41.16 on the purchase of bricks
