The coordinates of the other endpoint of the diameter of the circle are (-2,-3)
Answer: 25.6
First, notice that there is 1 adult and 2 children.
A normal adult ticket costs 24. But it's 1/3 off, so 24 * 1/3 = 8 off. That means with the Railcard, it only costs 24 - 8 = 16.
Next, one child ticket costs 12. But it's 60% = 3/5 off, so 12 * 3/5 = 7.2 off. That means with the Railcard, it only costs 12 - 7.2 = 4.8.
Remember there are 2 children, so we multiply by 2 to get 4.8 * 2 = 9.6 for the children.
Final answer: 1 adult + 2 children = 16 + 9.6 = 25.6.

Answer:
a) 0.85
b) 0.0160
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a saple of size n, the mean of the sampling distribution of sample means is p and the standard deviation is
In this problem, we have that:
(a) Calculate the mean of the sampling distribution of the sample proportion.
By the Central Limit Theorem, 0.85
(b) Calculate the standard deviation of the sampling distribution of the sample proportion. (Round your answer to four decimal places.)

Answer:
Obtuse
Step-by-step explanation:
I really don’t know which angle they’re asking for because the 140 degree angle is obtuse and the 40 degree angle is acute
