1.
the closest perfect squares of 12 are 9 and 16,
that is 9<12<16
so


this means,

is 3 point something...
2.
similarly
36<40<49
so


which means

is 6 point something...
3.
<span>the sum of the integers between the square root of 12 and 40 is the sum of 4, 5 and 6, since 4 is the smallest integer after root 12, and 6 the greatest integer to before root of 40.
Answer: 15</span>
What is the lower quartile of the data? 16, 18, 59, 75, 30, 34, 25, 49, 27, 16, 21, 58, 71, 19, 50

Answer:
19.
Step-by-step explanation:
First arrange in ascending order:
16, 16, 18, 19, 21, 25, 27, 30, 34, 49, 50, 58, 59, 71, 75.
There are a total of 15 numbers, so the median is the 8th number = 30.
The lower quartile is halfway alone the first 7 numbers which is the 4th number and it is 19.
The median which is the middle number
Answer:
19 degrees (see attached)
Step-by-step explanation:
Answer is C! Hope it helps
Okay so every triangle will have 3 angles that add to 180 degrees. You are given that A=65 which means that B + C will have to add to 115. You are given that B= (3x-10) and C=2x, plug this into B+C=115. So
3x-10+2x=115, isolate x, 5x=125, divide both sides by 5 and you get that x=25. This makes B=65, and C=50. Just to check, if you add these together you get 180 degrees.
