Answer:
(-1, -3) and (1, 1)
Step-by-step explanation:
Use a graphing calculator to graph out both lines:
(See picture)
Both lines intersect at points (-1, -3) and (1, 1). These are the solutions for the system of equations.
Answer:
-5
Step-by-step explanation:
4x0.5=2
2x0.5=1
2+1=3
3-8=-5
Pi is multiplied by diameter so,
35 x pi= 109.995
tell me how many decimal places should the finals should be so that I can round off
Answer:
For this case we want to conduct a test in order to see if the proportion of Clemson students who eat breakfast is different from 0.44 (alternative hypothesis). And the complement would represent the null hypothesis, and the system of hypothesis for this case are:
Null Hypothesis: ![p =0.44](https://tex.z-dn.net/?f=%20p%20%3D0.44)
Alternative hypothesis: ![p \neq 0.44](https://tex.z-dn.net/?f=%20p%20%5Cneq%200.44)
Step-by-step explanation:
Previous concepts
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
Solution to the problem
For this case we want to conduct a test in order to see if the proportion of Clemson students who eat breakfast is different from 0.44 (alternative hypothesis). And the complement would represent the null hypothesis, and the system of hypothesis for this case are:
Null Hypothesis: ![p =0.44](https://tex.z-dn.net/?f=%20p%20%3D0.44)
Alternative hypothesis: ![p \neq 0.44](https://tex.z-dn.net/?f=%20p%20%5Cneq%200.44)
Given :
Center of circle, C = ( 1 , 5 )
Point on circle, P = ( 5 , 1 )
To Find :
The radius of a circle.
Solution :
We know, radius of circle is the distance between center and point of circle.
Distance between two points A(p,q) and B(r,s) is given by :
![D = \sqrt{(p-r)^2+(q-s)^2}](https://tex.z-dn.net/?f=D%20%3D%20%5Csqrt%7B%28p-r%29%5E2%2B%28q-s%29%5E2%7D)
So, distance between the points (1, 5) and (5, 1) is :
![D = \sqrt{(1-5)^2+(5-1)^2}\\\\D = 5.66 \ units](https://tex.z-dn.net/?f=D%20%3D%20%5Csqrt%7B%281-5%29%5E2%2B%285-1%29%5E2%7D%5C%5C%5C%5CD%20%3D%205.66%20%5C%20units)
Therefore, radius of circle is 5.66 units.
Hence, this is the required solution.
