Answer:
19 is the area for the problem
"The square of x" means x^2, so we can eliminate options A and D.
"product of 8 and x" means that 8 and x are multiplied together (like 8x)
If x^2 is increased by 8x, we are adding x^2 and 8x together.
<span>B. x^2 + 8x</span>
It already tells you that he ran 100 meters so what you need to do is convert kilometer to meter and centimeter to meter.
1 kilometer is is 1000 meters. 1 meter is 100 centimeters.
So 5000 centimeters is 50 meters.
Add 100 + 50 + 1000 =
1,150 meters :)
Answer:
e. We are 90% confident that the average age of all golfers that play on the golf course is between 38.6 and 44.6 years old.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
90% confidence interval for the average age of golfers in the course is of (38.6, 44.6). This means that we are 90% sure that the true average age of all golfers in the course is between these two values, that is, the correct answer is given by option e.
the answer in point-slope form is y = 1/4x-2 so your y-intercept is -2 and from there, move up one and right four. your points would be (0, -2) and (4, -1)
hope this helped! :)
