-9y+11-11=-6y+8-11
-9y=-6y-3
-9y+6y=-6y-3+6y
-3y=-3
Answer: y=1
M<A + m<B + m<C = 180
80 + 3x + 5 + <span>5x - 1 = 180
8x + 84 = 180
8x =96

<span>INFERENTIAL STATISTICS uses a sample data from a portion of
the whole population in order to draw a sound result from them and assume that
the result is based on the whole population. For example, in a population of
100 only 10 of the children can be picked from the population pool and be
conducted with the study. The result of the study is automatically inferred as
judgment that is probable and accurate. For example, if in a sample of 10, 3
out of 10 children are malnourished, it is automatically applied that 30 out of
the 100 children are malnourished. </span>
Answer: (1) D (2) C (3) 168 ft²
<u>Step-by-step explanation:</u>
1)
The length of the stamp is 8 - 6 = 2
The width of the stamp is 5 - 3 = 2
A = length x width
A = 2 x 2
= 4
Answer: D
2)
<u>Figure I</u> is a Rectangle and a Triangle
Rectangle: A = length x width
= 3 x 3
= 9
Area of Rectangle + Triangle = 9 + 3 = 12
<u>Figure 2</u> is a Trapezoid and a Triangle
Area of Trapezoid + Triangle = 12 + 4 = 16
<u />
<u>Figure III</u> is Rectangle and a Triangle
Rectangle: A = length x width
= 3 x 5
= 15
Area of Rectangle + Triangle = 15 + 7.5 = 22.5
The order from least to greatest is: I, II, III
Answer: C
3)
A = length x width
= 14 x 12
= 168
Answer:
Step-by-step explanation:
Y= 4x- 1 ;y = 11 find the value x
11 = 4x - 1
Collecting like terms
11 + 1 = 4x
12 = 4x
Divide through by 4
x = 12/4
x = 3
