Answer: r = 1.69 inches
h = 2.15 inches
Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.
Volume of a cone is directly proportional to radius and height:
They want the cones to hold the same volume of 9 cubic inches.
If height is 3:
r = 1.69 inches
When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.
If radius is 2:
h = 2.15 inches
If radius is 2 inches, height of the cone is 2.15 inches.
Answer:
2/6 or 1/3 so color 2 out of the six squares
Step-by-step explanation:
1/2 - 1/6 is equal to 3/6 - 1/6 so 2/6
Answer:
The population parameter of this study is the population mean.
Step-by-step explanation:
A population parameter is a numerical measure representing a certain characteristic of the population. For example, population mean, population variance, population proportion, and so on.
The population parameter is computed using all the values of the population.
The population parameter can be estimated using the sample statistic. If the value of the population parameter is not known, then a random sample of large size, say <em>n</em> ≥ 30 can be selected from the population and the statistic value can be computed. This statistic value is considered as the point estimate of the parameter. It is also known as the unbiased estimator of the parameter.
In this case the survey involved sampling of 1500 Americans to estimate the mean dollar amount that Americans spent on health care in the past year.
The sample selected is used to compute the sample mean dollar amount that Americans spent on health care.
So, the population parameter of this study is the population mean.
Plug in 500 for h in the equation and you get:
e=3 (500)
e=1500
Answer:
x = 4
Explanation:
−2x − 4 + 5x = 8
[ Simplify both sides of the equation ]
−2x − 4 + 5x = 8
−2x + −4 + 5x = 8
(−2x + 5x) + (−4) = 8 (Combine Like Terms)
3x + −4 = 8
3x − 4 = 8
[ Add 4 to both sides ]
3x − 4 + 4 = 8 + 4
3x = 12
[ Divide both sides by 3 ]
3x / 3 = 12 / 3
x = 4
