you will need to find the area
A=height multiplied by the base divided by 2
To find the margin of error, multiply the z-score by the standard deviation, then divide by the square root of the sample size.The z*-score for a 90% confidence level is 1.645.The margin of error is 0.20.The confidence interval is 48.3 to 48.7.48.8 is not within the confidence interval.
Answer:
The solutions to the system of equations are:

Thus, option C is true because the point satisfies BOTH equations.
Step-by-step explanation:
Given the system of the equations

Arrange equation variables for elimination






solve for x

Divide both sides by -2






The solutions to the system of equations are:

Thus, option C is true because the point satisfies BOTH equations.
Answer:
3!
Step-by-step explanation:
The vertices are the points of the triangle. So if you count each point you get 3!
Answer:
0.528 because its just moveing the decimal point to the right.
just so you can understand better.
