Studies indicate that about 10 percent of polar bears weigh more than 1,000 pounds. A biologist studying the bears thinks that p

ercent might be too high. From a random sample of polar bears, the biologist found only 8 percent of the sample weighing over 1,000 pounds. Which of the following is the most appropriate method for the biologist’s study?
A one-sample z
-test for a sample proportion
A one-sample z -test for a sample proportion

A one-sample z
-test for a population proportion
A one-sample z -test for a population proportion

A one-sample z
-test for a difference in population proportions
A one-sample z -test for a difference in population proportions

A two-sample z
-test for a difference in sample proportions
A two-sample z -test for a difference in sample proportions

A rocket is launched at the rate of 11 feet per second from a point on the ground 15 feet from an observer. To 2 decimal places
iragen [17]
Let the angle of elevation is x and the height of the rocket from the ground is y

tanx = y/15

by differentiating both sides with respect to T

sec²x·dx/dt = (dy/dt)/15

at y = 30 , the hypotenuse of the triangle = 15√5

sec²x=(15√5/15)²=5

5 dx/dt = 11/15

dx/dt = 11/75 rad/sec

s2008m [1.1K]

Answer:

k = 3

Step-by-step explanation:

Given that y and x are directly related then the equation relating them is

y = kx ←  k is the constant of variation

To find k use the condition y = 81 when x = 27

k = \frac{y}{x} = \frac{81}{27} = 3

Select the values for a, b, and c that will make the following equation true.
vodomira [7]

Step-by-step explanation:

(x + 8)(x - 1) = x^2 - x + 8x - 8 = x^2 + 7x - 8.

Hence a = 1, b = 7, c = -8. (Options A, D and E)
