Exactly what was your answer for a
Y=ax2+bx+c . In this equation, the vertex of the parabola is the point (h,k) . You can see how this relates to the standard equation by multiplying it out: y=a(x−h)(x−h)+ky=ax2−2ahx+ah2+k .
Answer:
A ≈ 78.5
Your answer was wrong because it said to round to the nearest tenth.
Step-by-step explanation:
First, to find the area of a circle, you need the radius or diameter of a circle. You can see that the radius is 5 (counting the units from E directly horizontal to the edge of the circle).
Area of a circle is:
A = πr²
A = π (5)²
Following PEMDAS (order of operations), you would do the exponent first:
A = π (25)
A ≈ 78.5
Answer:
Step-by-step explanation:
Given that the chocolate factory "Charlie’s own" produces limited-time boxes with exactly 9 chocolates.
X is the weight of chocolate
X is N (5, 0.3) (since variance = 0.09, std dev =sqrt of variance = 0.3)
Probability for the box to weight <42.75 =
P(X<42.75)
=
Or 0.62% of boxed weigh <42.75
10 + 3 = 6 + x
13 = 6 + x
13 - 6 = 6 - 6 + x
7 = x
Therefore, 7 is equal to 7. Hope this helps!
