The baseball team needs new equipment. Company A can provide 9 helmets, 6 bats, and 12 balls for $525. Company B can provide 10
Olin [163]

Answer:

Choice A.

Step-by-step explanation:

Let x = price of a helmet, y = price of a bat, z = price of a ball.

Company A can provide 9 helmets, 6 bats, and 12 balls for $525.

9x + 6y + 12z = 525

Company B can provide 10 helmets, 8 bats, and 10 balls for $600.

10x + 8y + 10z = 600

Company C can provide 8 helmets, 5 bats, and 15 balls for $500.

8x + 5y + 15z = 500

Answer: Choice A.

Archie is stranded in a war zone in the land of the Xhosas. His only chance of survival is to reach Sudland, which lies 100 mile
LenaWriter [7]

Answer:

The  chances of success for Archie is P(S|D) =  35\%

Step-by-step explanation:

From the question we are told that

 The distance of Sudland from Xhosas is   d =  100 miles

  The probability  of failure is  P(F) = 0.26

  The probability of choosing the desert route is   P(D) = \frac{1}{40} =  0.025

The probability of reaching Sudland through the mountain is  P(S|M) =0.75

Generally the probability of choosing the  mountains route is

         P(M) = 1 - P(D)

           P(M) = 1 - 0.025

             P(M) = 0.975

Generally the probability of success is mathematically represented as

       P(S) =  1- P(F)

         P(S) =  1- 0.26

          P(S) =  0.74

       

Generally the probability of success in reaching Sudland is also mathematically represented as

     P(S) =  P(S|M) * P(M) + P(S|D) * P(D)

=>   P(S|D) =  \frac{P(S) - P(S|M) * P(M)}{P(D)}

substituting values

=>  P(S|D) =  \frac{0.74 - 0.75 * 0.975}{0.025}  

=>  P(S|D) = 0.35  

=>  P(S|D) =  35\%
