P(total of 3) = 2C1 * (0.5) * (0.5) = 2 * 0.25 = 0.5 = 1/2
Answer:
728.1
Step-by-step explanation:
Answer:
The bottom graph on the right, check the image below:
Explanation:
Substitute the x value with 1,
f(1)=1(1+2)=3
f(2)=2(2+2)=8
f(-1)=-1(-1+2)=-1
f(-2)=-2(-2+2)=0
Let the actual size be x, then
(5 x 10^2)x = 1.2 x 10^2
x = (1.2 x 10^2 / 5 x 10^2) = 0.24 millimeters
Therefore, the actual size is 0.24 millimiters.
Answer:
A, B, and C
Step-by-step explanation:
The equilateral triangle refers to its equivalent sides and angles. So automatically, D would be ruled out.
Equilateral triangles have the same angles, so that would rule out E, because one 90° angle means it is a right triangle. Based on the explanation above, the answer would be A and B. C can be confusing but here's the explanation:
A triangle's sum of interior angles is 180°, so if a triangle has three sides, it also has three angles. So if you divide 180 into 3 equal parts, you get 60° each. So technically C is correct.
Answers: A, B, and C.
