Answer:
12.53
Step-by-step explanation:
∠BCA = (180°-40°)/2 = 70°
Laws of Sines: CA/sin 40° = AB/sin 70° = 5/sin 70°
CA = 5/sin 70° * sin 40° = 3.40
area of semicircle CA = (3.1416 * 1.70²) / 2 = 4.54
By Heron's Formula, area of triangle ABC:
1/4 √(a+b+c) (a+b-c) (b+c-a) (c+a-b) = 1/4 * √13.4*3.4*3.4*6.6
= 7.99
Entire region area = 4.54 + 7.99 = 12.53
The next 3 equivalent ratios are
4:2
6:3
8:4
10:5
Hope this helps!
Answer:
-1.5
Step-by-step explanation:
As you can see, to calculate the midpoint of 2 numbers, we sum them together and then divide by 2, we got:
(-6 + 3) / 2
= -3 / 2
= -1.5

Answer:
A distribution is skewed when one tail is longer than the other.
Step-by-step explanation:
- A negative skew might be a straight-ish line that will stay constant for some of the chart and then will go up, and finally come down.
