Answer:

CosQ = +- 15/17

Step-by-step explanation:

As it is seen in the attachment that the two individuals Keisha and David tries to find the value of TanQ, SecQ, SimQ and CosQ. The steps in the attachment is fairly correct which is why the answer for both individuals are accurate. To What's more identified by Keisha is the solution for using TanQ and SecQ. Similarly, David finds out by basic SinQ and CosQ values. Consequently both will give same value CosQ = +- 15/17 at end therefore they both are correct.

12345 [234]

Answer:

a) e probability that a randomly selected baseball has a weight greater than 5.14 ounces

=P(X>5.14) =(b-x)/(b-a) =(5.155-5.14)/(5.155-5.085)=0.2143

probability that a randomly selected baseball has a circumference less than 9.03 inches

=P(X<9.03) =(x-a)/(b-a) =(9.03-9)/(9.1-9)=0.3

c) probability that a randomly selected baseball will have a weight between 5.11 and 5.13 ounces and a circumference between 9.04 and 9.06 inches

=((5.13-5.11)/(5.155-5.085))*((9.06-9.04)/(9.1-9.0))=0.0571
