Answer:
Step-by-step explanation:
Circle - A = πr²
Semi circle - A= 1/2 πr²
Trapezoid - A= 1/2 (base 1 + base 2 ) x height
Rectangle - length x width
Triangle - A= 1/2 base x height
Answer:
Part b would be 4 and c would be 5 and d would be 19
Step-by-step explanation:
So yea do those
Answer:
As shown in picture, this is an isosceles right triangle ( A = 90 deg, B = C = 45 deg). => Except hypotenuse, side1 = side2, or x = 
Hope this helps!

Answer:
b= -4.68
Step-by-step explanation:
Hello!
We have to study variables:
Y: Monthly coffe sales
X: Price per pound of coffe ($)
The estimate regression line is
^Yi= a + bxi ∀ (i=1,.....,10)
The slope of the estimated regression line is represented by b.
The formula I'll use to calculate it is:
b= [n∑xiyi -(∑xi)*(∑yi)]/ n∑xi²-(∑xi)²
To calculate b we need to do some auxiliary calculations:
∑xiyi= 4213.15
∑xi= 87.47
∑yi= 545
∑xi²= 883.3703
Then we replace the formula:
b= [10*4213.15-(87.47)*(545)]/ n883.3703-(87.47)²
b= -4.68
I hope you have a SUPER day!
Answer:
1) 8 2) -33/9
Step-by-step explanation:
1) (1/2)x = -1/2 + 9/2
(1/2)x = 4 x = 8
2) distributing 3/2, 9x/2 - 15/2 = -24
9x/2 = -24 + 15/2
9x/2 = -33/2
9x = -66/2
9x = -33
x = -33/9
