Answer:
the probability is 4/9 (44,44%)
Step-by-step explanation:
Assuming that each point inside the square is equally probable, then the probability is uniformly distributed in area of the square. Thus
probability = area where condition is true / total area of the square
for a circle of radius 1/3 inside the square ,the area where this condition is satisfied is a square with sides 1-1/3 = 2/3 , thus
probability = (2/3)²/1² = 4/9
thus the probability is 4/9 (44,44%)
Answer:
Constant of proportionality
K= 16.5 gallons per minute
Step-by-step explanation:
Time t (minutes) Water g (gallons)
For t= 1, g= 16.50,
for t= 1.5 ,g= 24.75
For t= 2,g= 33
Let the function be
Gallons g= k(time t)
Where k is the constant of proportionality
16.5= k(1)....for when t= 1
24.75= k(1.5) ..for when t= 1.5
Solving gives
8.25=k(0.5)
8.25/0.5= k.
16.5 = k
K= 16.5 gallons per minute
It is A because at zero weeks she had 6 dollars (zero weeks is before she started working) and continued to get paid that one dollar per week the amount she gets per week is consistent and isn’t going to change therefore the answer is a
The area for 7 is the area of the rectangle- the area of the triangle.
A=15x10 - (1/2)x8x5
A=150 - 20
A=130
The area for 8 is the square - the half-circle
A= 4x4 - half-circle
A=16 - half-circle
Now a circle has an area of pi*r^2
Half that circle has an area of 1/2 pi r^2
The diameter of the circle is 4 so the radius is 2
A= 16 - (1/2)x Pi x(2)^2
A= 16 - 2pi
That's the "exact" answer, for an estimation plug 16 - 2*pi into the calculator
