What is the volume of this sphere that has a radius of 6 in

Answers

Answer 1

Answer: The volume of any sphere is

V = (4/3) x (pi) x (radius of the sphere)^3 .

Answer 2

Answer: $Volume=(4)/(3) \pi radius^3\n\nradius=6in\n\nVolume=(4)/(3) \pi (6)^3=(4 \pi*216 )/(3)=(864 \pi )/(3)=288 \pi in^3\n\nVolume\ is\ equal\ to\ 288 \pi in^3.$

Which value of K will make x^2-1/4x+k a perfect square trinomial?

Answers

For this case we have the following polynomial:
$x^2 - (1)/(4)x + k$
We suppose that we have a standard equation of the form:
$ax ^ 2 + bx + c$
To make a perfect square trinomial, we need to complete the square.
Therefore, the value of c is:
$c = ((b)/(2))^2$
Using this definition for this case, we have:
$k = (((-1)/(4))/(2))^2$
$k= ( (-1)/(8) )^2$
$k = (1)/(64)$
Therefore, the perfect square trinomial is:
$x^2 - (1)/(4)x + (1)/(64)$
Answer:
The value of k is:
$k = (1)/(64)$

1/64, because (-1/4)/2 is -1/8, and -1/8 ^2 is 1/64

Suppose you produce a camera that costs $50 to make. At a selling price of $45, you will _____.earn a profit
just cover your costs
lose money

Answers

Answer:

You will __$5___earn a profit just cover your costs lose money

Step-by-step explanation:

As per the statement:

Cost Price of the camera = $50

Selling price of the camera = $45

We have to find the profit that you will earn.

Since, $C.P > S.P$ then, you have suffer a loss.

Using formula:

$\text{Loss} = \text{Cost Price} -\text{Selling price}$

Then;

$\text{Loss} = 50-45 = \$5$

Thus, if you want to cover your costs lose money , then you will earn a profit of $5

You will lose money. Because $50 to make subtract $45 to sell (50-45) leaves you losing $5.

A survey of 1,000 men and women asked, "Do you earn over $50,000 per year?" The table below shows the responses for males and females:Male Female Total
Income over $50,000 485 385 870
Income below $50,000 65 65 130
Total 550 450 1,000

Based on these data, are "being male" and "earning over $50,000" independent events?

A) Yes, P(being male | the person earns over $50,000) ≠ P(being male)
B) Yes, P(being male | the person earns over $50,000) = P(being male)
C) No, P(being male | the person earns over $50,000) ≠ P(being male)
D) No, P(being male | the person earns over $50,000) = P(being male)

Male Female    Total
Income over $50,000   485 385   870
Income below $50,000 65   65 130
Total   550 450   1,000

Probability of being male: 550/1000 = 0.55
Probability of earning over $50,000: 870/1000 = 0.87

0.55 x 0.87 = 0.4785

Probability of being male and earning over $50,000: 485/550 = 0.8818

C) No, P(being male | the person earns over $50,000) ≠ P(being male)

Based on the date given "being male" and "earning over $50,000" are NOT mutually exclusive events. That is "No, P(being male | the person earns over $50,000) ≠ P(being male)" (Option C)

What are mutually exclusive (or independent) events?

Two events are independent or mutually exclusive if they are distinct from one another and cannot alter the reaction of one another.

Calculation

Probability of being male: 550/1000 = 0.55
Probability of earning over $50,000: 870/1000 = 0.87

=0.55 x 0.87

= 0.4785

Thus, probability of being male and earning over $50,000

= 485/550

= 0.8818

Hence, we can state that P(being male | the person earns over $50,000) ≠ P(being male)

An electrician charges a one-time fee of $75 plus $25 for each hour of service. If h is the number of hours and t is the total amount billed to the customer, then the variables are related by the equation t = 25h + 75.Which variable is the independent variable?

A.T

B.
There is no relationship between the variables.

C.H

Answers

If you would like to know which variable is the independent variable, you can do this using the following steps:

t = 25h + 75
h ... the number of hours ... independent variable
t ... the total amount billed to the customer ... dependent variable

The correct result would be C. h.
