Answer:
Option 2 is true.
Step-by-step explanation:
Th sum of probabilities of two complementary events is one, which implies
P(A) + P(B) = 1
So,
P(B) = 1 - P(A)
The arrangement of mother's eye level, ground level and playground forms a right angles triangle.
The legs of this triangle are 12.6 m (eye level to ground) and 20 m (building to playground).
Using trigonometry and assuming the depression angle is Ф;
tan Ф = 20/12.6 = 1.5873
Ф = tan ^-1(1.5873) = 57.78°
You must calculate h(24) first. h(x) = x^2 + 1, so h(24) = 577.
g(x) = 3x, so g(577) = 3(577) = 1731 (answer). We don't need f(x).
To find a midpoint of two points, add the 2 x values together and divide by 2, then do the same with the Y values:
Midpoint of X = 3 +2 = 5/2 = 2.5
Midpoint of Y = 5+2 = 7/2 = 3.5
Midpoint = (2.5,3.5)
Answer:
Sofias solution is correct.
Step-by-step explanation:
First of all you do not need two sets of the same equation.
y=-1.5x + 5.7
y = 0.5x + 0.3
If you graph the y-intercepts first then graph the slope for the equation then you will get the right answer.
1) Graph 5.7 on the y-axis. | Then graph -1.5x going down on the y-axis and then go to the right on the x-axis.
Do the same for the other equation and you will get a solution of (2.7, 1.65) since they will intersect there.
