Answer:
-14
Step-by-step explanation:
the coordinate of I :
H = 8+I /2
-3 = 8+I /2
8+I = 2×(-3)
8+ I = -6
I = -6-8
I = -14
Answer:
9 : 24
Step-by-step explanation:
Sum the parts of the ratio, 3 + 8 = 11 parts
Divide 33 by 11 to find the value of one part of the ratio
33 ÷ 11 = 3 ← value of 1 part of the ratio, thus
3 parts = 3 × 3 = 9
8 parts = 8 × 3 = 24
Answer:
4 units squared
Step-by-step explanation:
The area of the rectangle is 9 units squared
The area of the two wedge-shaped triangles on the outside of the larger triangle is 3 units squared. The final triangle area is 2 units squared. Thus 9 - 5 = 4 units squared.
The mean is the average. Add all the numbers together, then divide by the quantity of numbers in the data set.
1040 / 13 = 80
The mean is 80
