Answer: I think it might be 3.5 hours
Step-by-step explanation: 4 - 1.5 = 3.5
I'm not 100% sure but hope this helps!
OK. What are the known facts? We need 20 servings, and 1/3 cup is for 8. Let's move things around. Think as if 1/3 was for 5 people. That would mean you would need 1 1/3 cups for 20 servings. Because 5*4 is 20 and 1/3*4 is 1 1/3. Now for the extra 3. There are 4 sets of 3 total left, which is 12. 12 is 1 1/2 of 8, so we need 1/3 cup and half of 1/3. I don't want to give the entire thing away, so I will leave that for you to figure out! Bye :D
Answer:
<h2>
min: 52</h2><h2>
max: 78</h2><h2>
median: 63</h2><h2>
lower quartile median: 54</h2><h2>
upper quartile median: 73</h2><h2>
interquartile range: 19</h2>
Step-by-step explanation:
the temperatures ordered from least to greatest
52, 53, 54, 54, 57, 62, 64, 69, 73, 73, 77, 78
the min is 52
the max is 78
median:
52, 53, 54, 54, 57, 62, 64, 69, 73, 73, 77, 78
(62+64)/2=126/2=63
thus the median is 63
now we don't include the median in finding the upper and lower quartile medians:
lower quartile median:
52, 53, 54, 54, 57, 62
54 (same #s no need to add up and divide by 2)
upper quartile median:
64, 69, 73, 73, 77, 78
73 (same #s no need to add up and divide by 2)
interquartile range is:
upper quartile median-lower quartile median:
73-54
19
Answer:
ΔABC is not a right- angled triangle
Step-by-step explanation:
Given AB = 8, BC = 5
Then AC = 22 - (8 + 5) = 22 - 13 = 9 cm
Using the converse of Pythagoras' identity
If the square of the longest side equals the sum of the squares of the other 2 sides then triangle is right.
AC² = 9² = 81
AB² + BC² = 8² + 5² = 64 + 25 = 89
81 ≠ 89, hence ΔABC is not right- angled
