The probability that a company will launch the product A and B are 0.45 and 0.60 respectively, in main while, probability that b
Brrunno [24]

Answer:

a) what is the probability that Neither will of these products launch ?

= 0.30

b) At least one product will be launched ?

= 0.70

Step-by-step explanation:

From the above question, we have the following information:

P(A) = 0.45

P(B) = 0.60

P(A ∩ B) = P(A and B) launching = 0.35

Step 1

We find the Probability that A or B will launch

P (A ∪ B) = P(A) + P(B) - P(A ∩ B)

= 0.60 + 0.45 - 0.35

= 1.05 - 0.35

= 0.70

a) what is the probability that Neither will of these products launch ?

1 - Probability ( A or B will launch)

= 1 - 0.70

= 0.30

b)At least one product will be launched?

This is equivalent to the probability that A or B will be launched

P (A ∪ B) = P(A) + P(B) - P(A ∩ B)

= 0.60 + 0.45 - 0.35

= 1.05 - 0.35

= 0.70

Mr. Selan loves the 99-cent menu at Wendy's (sadly prices went up a few years ago). He used to buy two chicken sandwich at 99-ce
iogann1982 [59]

Answer:

Mr. Selan would pay $2.15 for the sandwiches with tax.

Step-by-step explanation:

Given that:

Cost of each sandwich = 99 cents

Cost of two sandwiches = 99*2 = 198 cents

Sales tax = 8.5%

Sales tax = \frac{8.5}{100}*198=16.8\ cents

Sales tax = 17 cents

Total cost = 198 + 17 = 215 cents

Total cost = $2.15

Hence,

Mr. Selan would pay $2.15 for the sandwiches with tax.

The point (2, 3) is on the terminal side of angle Θ, in standard position. What are the values of sine, cosine, and tangent of Θ
stira [4]

Answer:

sin Ф = 3/√13; cos Ф = 2/√13; and tan Ф = 3/2

Step-by-step explanation:

Let's assume we're limiting ourselves to Quadrant I.

Start with the tangent function.  tan Ф = opp / adj.

In this case opp = 3 and adj = 2.  

The length of the hypotenuse is found using the Pythagorean Theorem and is √(3² + 2²) = √13.

Then sin Ф = opp / hyp = 3/√13 or 3√13/13

and

cos Ф = adj / hyp = 2/√13 or 2√13/13

and (as before)

tan Ф =  opp / adj = 3/2
