Answer:

37.68 ft^3

Step-by-step explanation:

The parameters used in describing a cone is radius and height

Hence

Radius= 3ft

Height = 2 ft

The volume of a cone is given as

$v=\frac{1}{3} \pi r^2 h$

substitute

$v=\frac{1}{3}*3.14*3^2*2^2\\\\v=\frac{1}{3}*3.14*9*4\\\\v=\frac{1}{3}*113.04\\\\v=37.68 ft^3$

Hence the volume is 37.68 ft^3

Answer:

The best conclusion is that we are 90% that the true population proportion of Republicans that voted for Mitt Romney is between 0.7273 and 0.8106.

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:

The 90% confidence interval for the proportion of Republican voters that had voted for Mitt Romney is (0.7273, 0.8106). The best conclusion is that we are 90% that the true population proportion of Republicans that voted for Mitt Romney is between 0.7273 and 0.8106.

Construct the graph of the equation y=kx if it is known that the point B belongs to the graph. The graph of which of these two e

PIT_PIT [208]

Answer:

The graph with B(2,-3) i.e) y= $\frac{-3}{2}$ x goes through the point M(-10,15).

Step-by-step explanation:

Consider M(-10,15) and given that equation is y = kx.

Now, substitute M(-10,15) in the equation

⇒ 15 = k × -10

⇒ k = $\frac{15}{-10}$ = $\frac{-3}{2}$

⇒ y = $\frac{-3}{2}$ x

Now, check with the given points B(2,-3) and B( $3\frac{1}{3}$ , -2)

1) B(2,-3)

y = $\frac{-3}{2}$ x

⇒(-3) = $\frac{-3}{2}$ × 2

⇒ -3 = -3 ⇒ LHS = RHS

⇒ B(2,-3) is the required point.

2) for b( $3\frac{1}{3}$ , -2)

LHS ≠ RHS.

So,The graph with B(2,-3) i.e) y= $\frac{-3}{2}$ x goes through the point M(-10,15).
