Hello!
First we have to find the median
We have to order the numbers from least to greatest
72, 83, 87, 90, 97, 101, 114, 117, 142
The median is 97
Next we have to find quartile 1
you look for the median for the numbers under 97
It is 83 and 87
You get the average
83 + 87 = 170
170 / 2 = 85
quartile 1 is 85
Next we find quartile 3
Look for the median for the numbers above 97
The numbers are 114 and 117
Get the average
114 + 117 = 231
231/2 = 115.5
Now you find the range between the quartiles
You do quartile 3 - quartile 1
115.5 - 85 = 30.5
The answer is 30.5
Hope this helps!
Answer:
15 grams
Step-by-step explanation:
If the copper made up 80% of the weight of the bar (w), then the bar weighed ...
0.80w = 12 g
w = (12 g)/0.80 = 15 g
_____
Copper has a density of about 8.96 g/cm³, so Nancy's "large" metal bar is about the size of two sugar cubes.
In the deck there are 13 diamonds so 13 diamonds can be paired with any other of the 12, so 13x12.... if you are too lazy to do that... then idk
Answer:
a)
<u>Verify is the corresponding sides have same ratio:</u>
- AB / DE = 50/60 = 5/6
- BC / EF = 20/24 = 5/6
Since the ratios are same, the triangles are similar
b)
<u>If one dimension is same, the base areas will make difference by the square of the scale factor:</u>
Answer:
Ingredients · 10 pounds potatoes · 24 eggs · 4 cups mayonnaise · 1 tablespoon prepared yellow mustard · 4 teaspoons salt, or to taste · 2 teaspoons ground black ...
