Answer and explanation:
Geometary software is merely a software implementation of solving the area of a triangle. Therefore geometry software employs all the methods used in coordinate algebra(manual) albeit behind the scenes, in the console of the software, and just displays the area in the screen after solving. While geometry software displays the area using automated methods in code, coordinate algebra solves area of the triangle manually using several steps. In both cases, we observe that algebra is required to solve area of the triangle as it is part of the algorithm used in the code for the geometry software. Also being able to use the geometry software requires that one understand coordinate algebra to be able to plot lines, points and planes at the correct locations on the screen and get desired result.
Answer:
The 98% confidence interval for the probability of flipping a head with this coin is (0.4756, 0.7044).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of 
.
An experimenter flips a coin 100 times and gets 59 heads.
This means that 
98% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 98% confidence interval for the probability of flipping a head with this coin is (0.4756, 0.7044).
Answer:
the distributive property
Step-by-step explanation:
X=0
Y=-2
Multiply the top equation by -2 to get -2y=-8x+4
Isolate 2y on the bottom by subtracting 3x from both sides to get 2y = -4 - 3x
Add the two equations get 0=-11x so x = 0
Solve for y by plugging zero into one of the equations to get y=4(0)-2 to find the y = -2
y=4(0)-2
Answer:
x≤-4 or x≥0.5
