Find the volume of the cone, read the directions carefully!!

luda_lava [24]

Answer:

300 units^3 or 96π

Step-by-step explanation:

Volume of the cone would be:

Because the formula of finding the volume of cone is

V = πr^2 * h/3

r is the radius of the base

h is the height of the cone

π is Pi, approximately 3.142 and it is the circumference of any circle divided by its diameter

V is volume

So in this case:

V = πr^2 * h/3

V = π * 6^2 * 8/3

V = π * 36 * 8/3

V = 96π or 301.44 and round it up to 300 units^3

Answer:

<em>Probability ≈ 0.3571</em>

Step-by-step explanation:

Consider the steps below;

$Total Number of Outcomes - 9C4,\\9 ! / 4 ! * ( 9 - 4 ),\\9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 / 4 * 3 * 2 * 1 * 5 * 4 * 3 * 2 * 1,\\\\Total Outcomes = 126,\\\\Number of Outcomes - 3C2 * ( 6C2 ),\\3C2 = 3,\\6C2 = 15,\\\\Number of Outcomes = 3 * 15 = 45,\\\\Probability; 45 / 126 = ( About ) 0.3571$

<em>Solution; Probability ≈ 0.3571</em>

A store asked 250 of its customers whether or not they were satisfied with the service. The responses were also classified accor

anyanavicka [17]

Answer:

Correct option: e) a two-way table.

Step-by-step explanation:

In this case the store wants to see whether there is a relationship between the satisfaction level of the customer and their gender.

In statistics when there is a need to analyze or derive a relation between two categorical variables one should use a two-way table.

Categorical variables are qualitative variables that take on specific values that are usually labels. For example, grades obtained in an exam, gender, etc.

In this case the two categorical variables are: Gender and Satisfaction level.

To study the relation between the gender of a customer and their satisfaction level use a two-way table.

Solve logarithm Equation: log2 (12b - 21) - log2 (b^2 - 3)=2

Vikki [24]

Hn, well you should use the rule to answer this.. $log_a(n)-log_a(m)=log_a (\frac{n}{m} )$
Sorry if this doesn't seem to help, but here is the explanation:
$log_2 (\frac{12b-21}{b^2-3} )=2$
$\frac{12b-21}{b^2-3} =4$
$12b-21=4(b^4-3)$
$0=4b^2-12b-12+21$
$0=4b^2-12b+9
$
$0=4b^2-6b-6b+9$
$0=2b(2b-3)-3(2b-3)$
$0=(2b-3)(2b-3)$
$b= \frac{3}{2}$
Hn, so from this information we can determine that this solution does not work. And so forth your solution set shall indeed be: {x= 0}

I wish you good luck on your homework and hopefully I was somewhat beneficial to your needs.

Best regards~ Sans
