i think that you are multiplying them so the answer is 3553.5
and if your adding it would be 122.1
The cost of the sweater is given by the equation A = $ 40.69
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total cost of the sweater be represented as A
Now , the equation will be
The cost of sweater without discount and sales tax = $ 47.99
The discount percentage = 20 %
The cost of sweater after discount = 47.99 - ( 20/100 ) x 47.99
On simplifying the equation , we get
The cost of sweater after discount = 47.99 - 9.598
The cost of sweater after discount = $ 38.392
Now , the percentage of sales tax = 6 %
The cost of sweater after sales tax = 38.392 + ( 6/100 ) x 38.392
On simplifying the equation , we get
The cost of sweater after sales tax = 38.392 + 2.30352
The cost of sweater after sales tax = $ 40.695
Therefore , the value of A is $ 40.69
Hence , the final cost of the sweater is $ 40.69

To find the probability that exactly n cards are dealt before the first ace appears, we can use the concept of a geometric distribution. In a geometric distribution, we're interested in the number of trials (in this case, card draws) required for a success to occur (in this case, drawing an ace) for the first time.
The probability of drawing an ace in a single draw from a well-shuffled pack of 52 cards is 4/52 because there are 4 aces out of 52 cards.
So, the probability of drawing a non-ace in a single draw is (52 - 4)/52 = 48/52.
Now, let X be the random variable representing the number of cards drawn before the first ace appears. X follows a geometric distribution with parameter p, where p is the probability of success on a single trial.
P(X = n) = (1 - p)^(n - 1) * p
In this case, p is the probability of drawing an ace on a single trial, which is 4/52, and n is the number of cards drawn before the first ace.
So, the probability that exactly n cards are dealt before the first ace appears is:
P(X = n) = (1 - 4/52)^(n - 1) * (4/52)
Now, to find the probability that exactly k cards are dealt in all before the second ace appears, we need to consider two scenarios:
1. The first ace appears on the nth card, and the second ace appears on the kth card after that. This is represented by P(X = n) * P(X = k).
2. The first ace appears on the kth card, and the second ace appears on the nth card after that. This is represented by P(X = k) * P(X = n).
So, the total probability that exactly k cards are dealt before the second ace appears is:
P(X = n) * P(X = k) + P(X = k) * P(X = n)
You can calculate this probability using the formula for the geometric distribution with p = 4/52 as mentioned earlier for both P(X = n) and P(X = k).
Loan Y: 7.724% nominal rate, compounded monthly
Loan Z: 7.698% nominal rate, compounded weekly
a. Y only
b. X and Z
c. Y and Z
d. None of these meet Mike’s criteria.
Answer:
b. X and Z
Step-by-step explanation:
Since, the effective annual rate is,
Where r is the nominal rate per period,
m is the number of periods in a year,
For loan X,
r = 7.815 % = 0.07815
m = 2,
Thus, the effective annual rate,
Since, 7.968\% < 8.000 %
Thus, Loan X meets his criteria.
For loan Y,
r = 7.724%= 0.07724
m = 12,
Thus, the effective annual rate,
Since, 8.003 > 8.000 %
Thus, Loan Y does not meet his criteria.
For loan Z,
r = 7.698% = 0.07698
m = 52,
Thus, the effective annual rate,
Since, 7.996 % < 8.000 %
Thus, Loan Zmeets his criteria.
Hence, option 'b' is correct.
