Answer:
its a function
slope form:y+5=-1.18·(x-3)
(-2.5,1.5)
Step-by-step explanation:
65 mph ⇒ 1 hour = 65 miles
1 hour = 65 miles
2.5 hours = 65 x 2.5 = 162.5 miles
Answer: 162.5 miles
Answer:
Step-by-step explanation:
The larger the sample size, the lower the standard deviation. The standard deviation shows how the data is spread from the mean. Therefore, benefit of increasing the sample size when trying to estimate the mean from a sample average are
a. A reduction in the bias of the estimate.
b. A reduction in the variability of the estimate.
The width of confidence interval is determined by the margin of error
Margin of error = z × s/√n
A smaller standard deviation and increased size would result to a narrower confidence interval. Therefore, increasing the sample size does not result to an increase in the width of the resulting confidence interval.
X⁴ - 12x² + 36
This is the equivalent expression.
(x²-6)²
1) (x²-6)*(x²-6)
2) x²(x²) + x²(-6) -6(x²) -6(-6) (distributive multiplication)
3) x⁴ - 6x² - 6x² + 36 = x⁴ - 12x² + 36 (group together figures that are the same value)
Answer:
7536 ft^3
Step-by-step explanation:
Volume of a cone is 1/3(h*pi*r^2) First find radius, diameter/2, so the radius is 20 ft. Now plug in to find answer.
