Answer: W
Step-by-step explanation: I remember learning this in school> you can tell it’s a function because no numbers repeat themselves etc .
Answer:
3 batters
Step-by-step explanation:
For the past data, we have observed that:
15 batters have gotten a hit
5 batters have not
The total of batters that we have observed is
n = 15 + 5 = 20
Therefore, this means that based on the observed data, the probability that a batter gets a hit is:
where
n(h) = 15 is the number of batters that got a hit
After that, we want to know how many batters we will expect to get a hit in the next 4 batters. We can write it as:
And since
p(hit) = 0.75
We find:
So, we expect 3 batters to get a hit in the next 4.
Answer:
a.9
b. ay=9
xy= 18
Step-by-step explanation:
a. xa=ay (since a is a midpoint that means xa and ay are the same amount).
3x=5x-6
subtract 5x from both sides
-2x=-6
inverse operations, so divide both sides by -2. (a negative divided by a negative is a positive)
x=3
so xa=3x. fill in x
3*3 is 9
b. fill in the x
5*3-6
5 times 3 is 15.
15-6=9
(also xa is 9 and they are congruent so both are 9)
ay= 9
add both sides to find xy
9+9=18
xy=18
Answer:
3
Step-by-step explanation:
f(3) = 2*3 -3
= 6-3=3
f(f(3)) = f(3)
so again,
f(3) = 2*3 -3
= 6-3= 3
Answer:
4
Step-by-step explanation:
Here you need not completely solve 7992 squared. You can just take the last digit which in this case is 2 and solve for the square of that digit. 2 x 2 = 4. Now if it was a bigger digit which would result in a two digit number when squared you would take the last digit of that number. But, we don't need to do that here since 2 squared is 4.
