Answer: $9.86
Step-by-step explanation:
$11.60 ⋅ 8.5 = $98.60
$98.60 / 10 = $9.86
Answer:
0.771, 0.772, 0.773
Step-by-step explanation:
three numbers between 0.77 and 0.78
0.77 = 0.770
and
0.78 = 0.780
So,
0.770, 0.771, 0.772, 0.773, 0.780
= 0.77, 0.771, 0.772, 0.773, 0.78
$880, $896, $914, $925, and $963
median = $914
mean = (896+925+880+963+914)/5 = 4578/5 = $915.6
$915.6 - $914 = $1.6
so mean is greater than median $1.6
answer is B. second choice
<span>The mean is $1.60 greater.</span>
Answer:
<em>A.</em>
<em>The student made an error in step 3 because a is positive in Quadrant IV; therefore, </em>
<em />
Step-by-step explanation:
Given



Required
Where and which error did the student make
Given that the angle is in the 4th quadrant;
The value of r is positive, a is positive but b is negative;
Hence;

Since a belongs to the x axis and b belongs to the y axis;
is calculated as thus

Substitute 


Rationalize the denominator


So, from the list of given options;
<em>The student's mistake is that a is positive in quadrant iv and his error is in step 3</em>
45+(45*.15)=
45+6.75=51.75
6.75 is the tip, 51.75 is the total bill
