Answer:
An acute triangle is less than 90 degrees. What set of numbers equal less to 90 degrees?
Possible numbers: 30, 12, 16. These equal 58.
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>
--------------------------------------------------------------------------------------
Interquartile range:
<h2>
IQR: 334 - 223 = 111 </h2>

Answer:
Stem and Leaf Plot:
Stem Leaf
28 1 5 7 8
29 3 4 5
30 6 6 9
Minimum: 281
Maximum: 309
Range: 28
Count: 10
Sum: 2944
Mean: 294.4
Median: 293.5
Mode: 306
Standard Deviation: 9.709
Variance: 94.27
The answer is 2 in 20 or 1 in 10, all you have to do is add up the total number of marbles and then have the number of yellow in the total. So 2 in 20. Hope this helps you!
