289 196 248 379 319 276 198 349

(in order) 196, 198, 248, 276, 289, 319, 349, 379 there are eight numbers.

--------------------------------------------------------------------------------------

196, 198, 248, 276

since the median is between 198 and 248, we must add both numbers together and divide them by two:

(198 + 248) ÷ 2

= 446/2

<h2>= 223 (first quartile)</h2>

--------------------------------------------------------------------------------------

289, 319, 349, 379

since the median is between 319 and 349, we must add both numbers together and divide them by two:

(319 + 349) ÷ 2

= 668/2

<h2>= 334 (third quartile)</h2>

nevsk [136]

First, we have to get the fractions to common denominators.

4/5 = 16/20
1/4 = 5/20

5 5/20 - 3 16/20 = 1 9/20

She put 1 9/20 extra cups in.

What is the midpoint of the segment shown below?

kolbaska11 [484]

The midpoint of the segment is (-15/2, -15/2)

<h3>How to determine the midpoint?</h3>

The complete question is in the attached image

The points are given as:

(-8, -7) and (-7, -8)

The midpoint is calculated as:

(x,y) = 1/2 * (x1 + x2, y1 + y2)

So, we have:

(x,y) = 1/2 * (-8 - 7, -7 - 8)

Evaluate the difference

(x,y) = 1/2 * (-15, -15)

Evaluate the product

(x,y) = (-15/2, -15/2)

Hence, the midpoint of the segment is (-15/2, -15/2)
