Step-by-step explanation:
$44.80=($35+X)(1-0.3)
44.80 is the final total
You need to add the glove and hat cost to get a subtotal (35+x) and then multiply by what is left after the discount 30% off will leave 70% to pay, so in this equation 1-0.3 leaves 0.7 to multiply against the subtotal to get the total before tax of 44.80
We have m(<CBO) = (1/2) · m(<CBE) = (1/2) · ( x + z );
In the same way, m(<BCO) = (1/2) ·( x + y);
m(<BOC) = 180 - [(1/2) · ( x + z ) + (1/2) ·( x + y)] = 180 - (1/2)· ( x + x + y + z );
But, x + y + z = 180;
Then, m(<BOC) = 180 - (1/2)·( x + 180 );
Finally, m(<BOC) = 90 - (1/2)·x;
So, m(<BOC) = 90 - (1/2)·m(<BAC).
Answer:
A. 0.0001
Step-by-step explanation:
z-statistic:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
In this question:
The value of the z-statistic is z = 3.74.
The desired probability is 1 subtracted by the pvalue of z = 3.74.
z = 3.74 has a pvalue of 0.9999
Then
1 - 0.9999 = 0.0001.
So the correct answer is given by option A.
Answer: 
Step-by-step explanation:
<h3>
The missing data is: " The cost of renting a conoe to use on River Y costs $28. The cost of renting a conoe to use on River Z costs $3 per hour plus a $13 deposit".</h3>
Let's find the first equation.
You know that the cost of renting a conoe to use on River Y costs $28. This is:
To find the second equation you need to remember the Slope-Intercept form of a Linear equation. This is:
Where "m" is the slope and "b" is the y-intercept.
Since the cost of renting a conoe to use on River Z costs $3 per hour plus a $13 deposit, you can identify that:
Therefore, the equation that represents this situation is:
So, the System of equations that could be used to find the total cost "c" of renting a canoe for "n" hours, is:
