Answer: 220 in^3
Step-by-step explanation:
Area of the rectangle: 20x8 = 160
Area of right triangle: 8x15/2 = 60
Side of right triangle = 8, as the pythagorean triple 8,15,17 states C:
Area of the figure: rectangle + triangle = 160+60 = 220

<u><em>Answer:</em></u>
0.3
<u><em>Explanation:</em></u>
We are given that:
Probability that a randomly chosen person lives in the East is 0.12
P(East) = 0.12 ..................> I
Probability that a randomly chosen person lives in the West is 0.18
P(West) = 0.18 ............> II
Now, we want to find the probability that the randomly chosen person lives in the East or West
<u>To do this, we will use the following formula:</u>
P(A or B) = P(A) + P(B)
<u>Applying this rule to our givens:</u>
P(East or West) = P(East) + P(West)
P(East or West) = 0.12 + 0.18
P(East or West) = 0.3

The quadratic model is given by:
y = ax2 + bx + c
We evaluate three points to find the values of a, b and c.
We have then:
For (0, 200):
200 = a (0) 2 + b (0) + c
c = 200
For (0.5, 195):
195 = a * (0.5) ^ 2 + b * (0.5) +200
195-200 = a * (0.5) ^ 2 + b * (0.5)
-5 = 0.25a + 0.5b
For (1, 185):
185 = a * (1) ^ 2 + b * (1) +200
185-200 = a * (1) ^ 2 + b * (1)
-15 = a + b
Solving the system:
-5 = 0.25a + 0.5b
-15 = a + b
We have the following results:
a = -10
b = -5
Substituting:
y = -10x ^ 2 - 5x + 200
For x = 3 we have:
y = -10 (3) ^ 2 - 5 (3) + 200
y = - 90 - 15 + 200
y = 95
Answer:
the height at 3 seconds is:
y = 95 feet
D because if it’s liner then it’s probably positive... I’m not sure
Answer:
$10.75 per scarf
Step-by-step explanation:
Take the price and divide by the number of scarves.
$96.75 / 9 scarves
