Answer: 1, 13 is the answer
Answer:
31680 inches
Step-by-step explanation:
To find miles to inches, multiply by 63360 to get the answer.
0.5 x 63360 = 31680
So, he traveled 31680 inches.
A right triangle contains a right angle, so it must have two sides that are perpendicular. If the slopes of two sides can be shown to be negative reciprocals of each other, then it can be concluded that a right angle is formed. If a triangle contains a right angle, then it is a right triangle.
![- x + 1 = 4x - 14 \\ - x - 4x = - 14 - 1 \\ - 5x = - 15 \\ x = 3](https://tex.z-dn.net/?f=%20-%20x%20%2B%201%20%3D%204x%20-%2014%20%5C%5C%20%20-%20x%20-%204x%20%3D%20%20-%2014%20-%201%20%5C%5C%20%20-%205x%20%3D%20%20-%2015%20%5C%5C%20x%20%3D%203)
Substitute x = 3 in any given equations. I will do in y = - x + 1
![y = - x + 1 \\ y = - 3 + 1 \\ y = - 2](https://tex.z-dn.net/?f=y%20%3D%20%20-%20x%20%2B%201%20%5C%5C%20y%20%3D%20%20-%203%20%2B%201%20%5C%5C%20y%20%3D%20%20-%202)
Therefore the answer is (3,-2)
Answer:
0.01 is alpha level
Step-by-step explanation:
Given that a survey of a magazine of 1500 adults revealed that 12% chose chocolate pie.
i.e. p = proportion of people who like chocolate pie = 0.12
Margin of error = ±0.03
The value of q =1-\hat p , =1-0.12 = 0.88
The sample size n is given as 1500. Therefore, n=1500
The confidence level is given as 99%
Hence alpha = 1- confidence level
=1-0.99=0.01
Hence answer is 0.01
