A for both of them add all the numbers up and divide by the amount of numbers to get your iQR but A is right for both
The tangent to 
at the point (0, 5) has a slope equal to the derivative evaluated at 
.
This tangent passes through the point (0, 5), so its equation is
The normal line passes through the same point, but is perpendicular to the tangent line, so its slope is the negative reciprocal of the slope of the tangent. So the equation for the normal line is
Answer:
Step-by-step explanation:
a. no. 9 x 15 = 135, so if she sells more than 15 necklaces, she'll make a profit
b. 50n > 135 + 4.50n
Fixed price costs
Crew salaries 350
fuel 120
overheads 170
Total fixed cost: 640
Variable costs per passenger
refreshments $ 6.50
refund $ 3.64
total variable cost: 10.14
Sales income
<span>Average ticket $ 36 .40
</span><span>Break-even point = <u> (fixed costs) </u>
(income per passenger – costs per passenger) </span><span>
</span>
Break even = 640 / (36.40-10.14) = 640 / 26.26 = 24.37
