6 0

Answer:

The answers are 0, -6, 6

Step-by-step explanation:

So we have the equation:

6x(x^2 - 36) = 0

Multiply 36 x 6(the outside number)

6x(x^2 - 216)

Add x and x^2

6x^3 - 216 = 0

Now lets get rid of the exponents.

Split -216 into two equations. 6 x -6 = -216.

So the equations we have are:

(x + 6) and (x - 6)

Put this together with the 6x we have:

6x(x + 6)(x - 6) = 0

Now separate them into three problems:

6x = 0, x + 6 = 0, x - 6 = 0

Find x for all of them.

The answers are 0,-6, and 6.

Btw this is what I think you meant by solving it. If I got the wrong idea, let me know and I’ll fix it.

Suppose the weights of the Boxers at this club are Normally distributed with a mean of 166 pounds and a standard deviation of 5.
lesya [120]

Answer:

0.1994 is the required probability.      

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 166 pounds

Standard Deviation, σ = 5.3 pounds

Sample size, n = 20

We are given that the distribution of weights is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

Standard error due to sampling =

=\dfrac{\sigma}{\sqrt{n}} = \dfrac{5.3}{\sqrt{20}} = 1.1851

P(sample of 20 boxers is more than 167 pounds)

P( x > 167) = P( z > \displaystyle\frac{167 - 166}{1.1851}) = P(z > 0.8438)

= 1 - P(z \leq 0.8438)

Calculation the value from standard normal z table, we have,  

P(x > 167) = 1 - 0.8006= 0.1994 = 19.94\%

0.1994 is the probability that the mean weight of a random sample of 20 boxers is more than 167 pounds

Which figures have a volume greater than 500 cubic inches? Choose all that apply.
yaroslaw [1]

Answer:

All shapes except the cone with 5in radius and 8in height

Step-by-step explanation:

Volume of the cylinder with radius 5in and height 8in is expressed as;

V = πr²h

V = 3.14*5²*8

V = 3.14*25*8

V = 628 square inches

The volume of the cylinder is greater than 500in³

Volume of the cone with radius 5in and height 24in is expressed as;

V = 1/3πr²h

V = 1/3*3.14*5²*24

V = 3.14*25*8

V = 628 square inches

The volume of the cone is greater than 500in³

Volume of the spheree with radius 5in is expressed as;

V = 4/3πr³

V = 4/3π(5)³

V = 4/3 * 3.14 * 125

V = 523.33 square inches

The volume of the sphere is greater than 500in³
