Answer:
A
Step-by-step explanation:
It's hard to see but when x is 6, y is 4.5. Just plug that into each equation and see which one is correct.

Answer:
The probability that exactly 19 of them are strikes is 0.1504
Step-by-step explanation:
The binomial probability parameters given are;
The probability that the pitcher throwing a strike, p = 0.675
The probability that the pitcher throwing a ball. q = 0.325
The binomial probability is given as follows;

Where:
x = Required probability
Therefore, the probability that the pitcher throws 19 strikes out of 29 pitches is found as follows;
The probability that exactly 19 of them are strikes is given as follows;
Hence the probability that exactly 19 of them are strikes = 0.1504
Answer:
x=4+(19)^1/2,x=4-(19)^1/2
Step-by-step explanation:
Choice A is the answer
Why? Because we start with 4, which is denoted a_1 = 4, and because we multiply each previous term by -3 to get the next term (which is what the second row of choice A says).
Answer:
50x
Step-by-step explanation:
The 17 is the loop product or 6. Do reverse division and add the 78 on step three. Good Luck!
