Answer:3.73248×10^5

Step-by-step explanation:

To write (12*6)^3 as a single power,

We gets

12 × 6=72

Therefore 72^2

=373248

As a single power

3.73248×10^5

If the radius of the right cylinder is 5 in and the radius of the oblique cylinder is 4 in, they will have the same volume as lo

steposvetlana [31]

Answer:

False

Step-by-step explanation:

The volume of a right cylinder is given by the formula:

$V=\pi r^2h$

And the volume if a oblique cylinder is <em>also</em> given by the formula:

$V=\pi r^2h$

Regardless of the height, if the radius are different, then the volume would not be the same.

Algebraically:

$\pi(4)^2h\neq\pi(5)^2h\\16\pi\neq25\pi$

A sales analyst listed the probabilities of profits and losses in dollars for a certain company. Find the mean for the probabili

kakasveta [241]

Answer: The mean for the probability distribution will be 69.25.

Explanation:

Since we given that

$At\ x_1= -500 ,P(x) = 0.076\\$

$At\ x_2= -250,P(x)= 0.191\\$

$At\ x_3=0, P(x)= 0.265\\$

$At\ x_4=250 , P(x)= 0.316\\$

$At\ x_5=500 , P(x)= 0.152\\$

As we know the formula for expectation of x i.e. known as mean for the probability distribution,

$E(x)=x\sum_{1}^{5} P(x)$

So, we apply this formula in our case,

$-500\times 0.076+(-250)\times 0.191+0\times 0.265+250\times 0.316+500\times 0.512=69.25$

$\mu = 69.25$

Hence, the mean for the probability distribution will be 69.25.

Find an equation in point-slope form for the line having the slope m= -5 and containing the point (7,2).

Juli2301 [7.4K]

Answer:

y - 2 = - 5(x - 7)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 5 and (a, b) = (7, 2) , thus

y - 2 = - 5(x - 7) ← equation in point- slope form
