Answer:
1/216 or 0.0046
Step-by-step explanation:
Rolling a '1' one time has a probability of 1/6. Rolling a die three times and getting a '1' each time is an independent event, meaning that no roll affects the probability of a '1' happening on any other roll. When calculating probability of independent events, multiply them together. So the probability of a '1' three times in a row is...
(1/6)(1/6)(1/6) = 1/216 or 0.0046
Answer:
2400
Step-by-step explanation:
y= -300x + 2400
-300 equals the slope
2400 is the y-intercept
Equation: y = mx + b
The degree is 4, because it has 4 zeros.
<h2>Writing an linear equation from a given scenario</h2>
Answer:
Choice B
<h3>
Step-by-step explanation:</h3>
<em>Please refer to my answer from this question to know more about writing a </em><em>linear</em><em> </em><em>equation</em><em> from a given scenario: </em><em><u>brainly.com/question/24599307</u></em>
Scenario: A submarine dives 
feet per minute.
We let 
, be the position of the submarine from sea level as a function of 
, the time (in minutes) since the submarine dived.
The given scenario states that for every minute, the position of the submarine <u>decreases</u> (because the submarine is going in a downward direction) by feet. So 
can be defined as 
.
Now we can select two points for the graph. We can select points 
and 
.
Evaluation of function:
Our points are 
and 
Choice A doesn't touch our chosen points. In Choice C, it would be the case if the submarine is going in upward direct.
So the correct graph is Choice B.
Answer:
$32
Step-by-step explanation:
To find the commission, multiply the rate by the sales:
commission = 5% × $640 = $32
He made $32 in commission.

<em>Additional comment</em>
Many calculators and all spreadsheets can work with percentages directly. If yours can't, or if you can't do this arithmetic mentally, you can use the equivalent decimal or fraction for 5%.
5% = 5/100 = 0.05 = 1/20
Then 5% × $640 = $640/20 = $64/2 = $32.
