Answer:
A right triangle
Step-by-step explanation:
It's where the altitudes all intersect. In a right triangle, the legs of the right triangle are the altitudes-- especially evident when the right angle is at the base. The altitude from the hypotenuse to the right angle also passes through the right angle.
Answer:
496.6
Step-by-step explanation:
circumference of circle=8pie^2
2*pie*r=8*pie^2
2*r=8*pie
2r=8*22/7
r=176/7÷2
r=12.57
Area of circle=pie*r^2
=22/7*12.57^2
=22/7*158
=496.6
Answer:
Median is the center of the numbers that you were given
Mode is the number that appears most often
Range is the difference between the lowest and highest numbers
Mean is the average
Step-by-step explanation:
Median: line all numbers up in order from greatest to least and then count to the center if there are 2 in the center add them and divide them by 2.
Mode: Count how many of each number
Range: Subtract the largest number from the smallest. 17-12=5 5 is the range
Mean: Add all numbers up and divide by the amount of numbers.
1+3+5+3=12
12/4 = 3, three is the mean

Answer:
b) We are 90% confident that the mean salary of all CEOs in the electronics industry falls in the interval $139,048 to $154,144.
Step-by-step explanation:
Confidence interval:
Confidence level of x%
We build from a sample.
Between a and b.
Intepretation: We are x% sure that the population mean is between a and b.
In this question:
90%
45 CEO's
Between ($139,048, $154,144).
So
We are 90% sure that the mean salary of all CEO's falls within this interval.
The correct answer is:
b) We are 90% confident that the mean salary of all CEOs in the electronics industry falls in the interval $139,048 to $154,144.
