Answer: x=2√3
sin θ= opposite side ÷ hypotenuse
sin 30°= √3÷ x
sin 30°= 1/2
Therefore,
1/2= √3÷x
1/2×x=√3÷x×x
x is cancelled off on the right hand side,
1/2×x=√3
1/2× x ×2=√3×2
1/2 and 2 cancel off on the left hand side,
x= 2√3

% compounded continuously. After 15 years, how much more money would Lillian have in her account than Melanie, to the nearest dollar?
Answers
Answer:
$8727
Step-by-step explanation:
The difference in investment values can be found by computing the value of each investment, then finding the difference. Here, we're concerned with investments compounded quarterly and compounded continuously.
a)Melanie's investment value is computed using the formula ...
FV = P(1 +r/n)^(nt) . . . . where P is the principal, r is the annual rate, t is the number of years
FV = $63,000(1 +0.07125/4)^(4×15) = $63,000(1.0178125^60)
FV = $181,721.94
__
b)Lillian's investment value is computed using the formula ...
FV = Pe^(rt)
FV = $63,000·e^(0.07375×15)
FV = $190,449.05
__
c)The amount more that Lillian has is ...
$190,449.05 -181,721.94 = $8,727.11
Lillian has about $8727 more than Melanie.

Honey is a technology company that provides online coupons to its subscribers. Honey's analytics staff has developed a classification method to predict whether a customer who has been sent a coupon will apply the coupon toward a purchase. For a sample of customers, the following table lists the classification model's estimated coupon usage probability for a customer. For this particular campaign, suppose that when a customer uses a coupon, Honey receives $1 in revenue from the product sponsor. To target the customer with the coupon offer, Honey incurs a cost of $0.05. Honey will offer a customer a coupon as long as the expected profit of doing so is positive. Using the equation
Expected Profit of Coupon Offer = P(coupon used) × Profit if coupon used + (1 - P(coupon used)) × Profit if coupon not used
determine which customers should be sent the coupon.
Customer Probability of Using Coupon
1 0.47
2 0.35
3 0.27
4 0.03
5 0.08
Determine the expected profit for each customer. Round your answers to the nearest cent. Enter negative value as negative number, if any.

, so these customers
- Select your answer -
the coupon
Answers
Based on the expected profit to Honey, and the probability of the various customers using the coupons, all customers except customer 4 should be sent coupons.
What is the expected profit for all customers?The profit to Honey if people use the coupons is:
= Revenue - Cost
= 1 - 0.05
= $0.95
The profit if the coupon is not used is the cost of $0.05.
Customer 1 expected profit:
= P(coupon used) × Profit if coupon used + (1 - P(coupon used)) × Profit if coupon not used
= (0.47 x 0.95) + ( (1 - 0.47) x -0.05)
= $0.42
Customer 2 expected profit:
= (0.35 x 0.95) + ( (1 - 0.35) x -0.05)
= $0.30
Customer 3 expected profit:
= (0.27 x 0.95) + ( (1 - 0.27) x -0.05)
= $0.22
Customer 4 expected profit:
= (0.03 x 0.95) + ( (1 - 0.03) x -0.05)
= -$0.02
Customer 5 expected profit:
= (0.08 x 0.95) + ( (1 - 0.08) x -0.05)
= $0.03
In conclusion, all customers expect customer 4 should be sent the coupons as they result in profits.

Two adults and one child go to a movie and pay $26. One adult and 3 children pay
$28. How much would it cost for one adult and one child to see the movie?
Answers
Answer:
adults pay $10
children pay $6
Step-by-step explanation:
x = adult
y = child
2x + y = 26
x + 3y = 28
you want to cancel out x or y
multiply -2 with (x + 3y = 28) which is -2x -6y = -56
2x + y = 26
-2x -6y = -56
-5y = -30
y = 6
put y back into an equation
2x + y = 26 is
2x + 6 = 26
x = 10
check the answer
Two adults and one child go to a movie and pay $26
20 + 6 = 26 : checks
One adult and 3 children pay $28
10 + 18 = 28 : checks
