You have to measure the angles and side on your own because you have to use a protractor/ruler.
But for classification:
1. acute triangle and 3 acute angles
2. right triangle and 1 right angle
3. isosceles triangle and 2 equal sides
4. equilateral triangle and 3 equal sides
Answer: D 10
Step-by-step explanation:
I think the correct answer would be A. The standard deviation is used than the variance because the units of variance are squared units. It does not say anything or is meaningless while standard deviation has the same units as the mean which is a measure of central tendency.
Answer:
3/8
Step-by-step explanation:
1/8 + 1/4 = 1/8 + 2/8 = 3/8
Note that 1/4 = 1/4 * 2/2 = 1*2 / 4*2 = 2/8
Answer:
24 cubic inches
Step-by-step explanation:
Whenever you are finding the volume you have to multiply by two plus a number times two. For example, since there is two depths, you have to multiply 3 by 2 plus the next number. Then, since there is two sides, you multiply 5 by 2 plus the next number. Finally, since there is only one base, you don't have to multiply by two.
(3×2)+(5×2)+8=24
Hope I explained well enough for you to understand.
