Answer:

see explanation

Step-by-step explanation:

Expressing as equations

9x + 10y = 297 → (1) ← that is B

8x + 5y = 194 → (2) ← that is D

To solve the system of equations, multiply (2) by - 2

- 16x - 10y = - 388 → (3)

Add (1) and (3) term by term to eliminate the term in y

(9x - 16x) + (10y - 10y) = (297 - 388), that is

- 7x = - 91 ( divide both sides by - 7 )

x = 13

Substitute x = 13 into either of the 2 equations and solve for y

Using (1), then

(9 × 13) + 10y = 297

117 + 10y = 297 ( subtract 117 from both sides )

10y = 280 ( divide both sides by 10 )

y = 28

Cost of a small box of candy = $13

Cost of a large box of candy = $28

If there is a 10% chance of sun tomorrow and a 20% chance of wind and no sun, what is the probability that it is windy, given th
professor190 [17]
Since there are two events happening simultaneously (windy and no sun), we can apply the concept of conditional probability here. P(A|B) = P(A∩B)/P(B) where it means that given B is happening, the probability that A is happening as well is the ratio of the chance for A and B to happen simultaneously over the chance of B to happen. For our case, this can be interpreted as P(A|B): it is the probability that it is windy (A) GIVEN that there is no sun (B) P(A∩B) : chance of wind and no sun P(B) : chance that there is no sun tomorrow The chance of P(A∩B) is already given as 20% or 0.20. Since there is 10% or 0.10 chance of sun, then chances of having no sun tomorrow is (1-0.10) = 0.90. Thus, we have P(A|B) = 0.2/0.9 ≈ 0.22 or 22%. So, answer is B: 22%<span>.</span>
