First, find the middle of the data and you get 4 numbers in each side, then find the median for both group: 100,120,130,188 and for 196,220,265,300, for the group 1 that median is Q1 and for the second the median is Q3, now the interquartile range is=Q3-Q1
so,Q1=(120+130)/2=125
Q3=(220+265)/2=242.5
IQR=Q3-Q1=242.5-125=117.5

The nutrition facts label on a container of dry roasted cashews indicates there are 161 calories in 28 grams. You eat 9 cashews

kati45 [8]

Divide calories by grams so 161 / 28= 5.75 now you know 1 gram has 5.75 calories so you multiply 5.75 * 12 to get 69. so 12 grams of <span>cashews = 69 calories </span><span />

Answer:

$x=5\sqrt{3}$

Step-by-step explanation:

Evaluate the Pythagorean Theorem for the triangle.

a² + b² = c²

5² + x² = 10²

25 + x² = 100

Subtract 25 from both sides.

x² = 75

Square root.

x = sqrt(75)

Expand the radical.

x = 5*sqrt(3)
