Answer:

A = 41.4°

Step-by-step explanation:

Reference angle = A

Length of Adjacent side = 6

Length of Hypotenuse = 8

Apply the trigonometric function, CAH.

Cos A = Adj/Hyp

Substitute

Cos(A) = \frac{6}{8}

A = Cos^{-1}(\frac{6}{8})

A = 41.4° (approximated to the nearest tenth)

A baseball player’s batting average is calculated by dividing the number of times a player got a hit by the total number of time
natita [175]

Answer: B > 40

Step-by-step explanation:

The batting average is usually represented not as a percentage (i.e. 32.0%), but instead as a decimal number with three places after the decimal. A batting average of 1.000 means that the player gets a hit every time he comes to bat, and an average of .000 means the player has no hits.

If after the first 10 games of the season, Samuel had 12 hits off of 33 at bats.

The battling average = 12/33

= 0. 3636

If in a row without a hit and the batting average dropping below 0.300, then the likely bats will be

12/B > 0.300

B > 12/0.300

B > 40 bats

Where B represents the number of bats.
