If you want to cheat, paste the formula in Wolfram Alpha. However, this one is not that difficult. From the fact that x and y are squared you can infer that this is a circle. The 9 reveals that the radius r^2 is 9, so radius is 3.
The (x-2) tells us that the circle is shifted to the right by 2. Likewise, y+1 shifts it down by one. So the center is at (2,-1). If the equation would be x^2 + y^2 = 9, you'd have a circle exactly on the origin.
Hopefully this helps you break down the equation and pick the right picture!
The slope of the interactive is 6
Angle D corresponds to angle Z, so they are congruent.
In a parallelogram, consecutive angles are supplementary.
m<C + m<D = 180
m<C + m<Z = 180
123 + 57 = 180
180 = 180
The statements may be true.
Answer:
a) 0.9961
b) 0.9886
Step-by-step explanation:
We are given the following information:
We treat passenger not showing up as a success.
P(passenger not showing up) = 0.10
Then the number of passengers follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 125
a) probability that every passenger who shows up can take the flight
b) probability that the flight departs with empty seats
Answer:
Question 58: 130.4
Question 59: x = 21
Question: 60: 60
Step-by-step explanation:
Question 58: A bisector cuts something into two equals halfs. Since <ABD is 65.2, you have to multiply it by two to receive your final answer of 130.4.
Question 59: A right angle is equal to 90 degrees. So 90 split into two is 45. you take the 45 and plug it into the equation: 45 = (2x + 3) to find your answer.
45 = 2x + 3
42 = 2x
21 = x
Question 60: A bisector cuts something into two equals halfs. Since <ABE is 30, you have to multiply it by two to receive your final answer of 60.
