389 children and 224 adults were at the pool that day.
Step-by-step explanation:
Cost of one child ticket = $1.75
Cost of one adult ticket = $2.25
Total people = 613
Total receipts worth = $1184.75
Let,
Number of children = x
Number of adults = y
According to given statement;
x+y=613 Eqn 1
1.75x+2.25y=1184.75 Eqn 2
Multiplying Eqn 1 by 1.75
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 0.50
Putting y=224 in Eqn 1
389 children and 224 adults were at the pool that day.

Answer:
- 16
Step-by-step explanation:
Evaluate f(2) by substituting x = 2 into f(x) , that is
f(2) = 3(2) - 3 = 6 - 3 = 3
Evaluate g(- 1) by substituting x = - 1 into g(x) , that is
g(- 1) = 8 - (- 1)² = 8 - 1 = 7
Thus
4f(2) - 4g(- 1)
= 4(3) - 4(7)
= 12 - 28
= - 16

Answer:
C. The data is skewed to the left and shows that she never scored fewer than 2 points or more than 12 points in a game.
Step-by-step explanation:
In the given image that is representing the number of points that Shira scored, each basketball game so far this season we can observe that the data is skewed to the left.
Lets consider the definition of skewness of a data set:
A left-skewed distribution has a long left tail. Left-skewed distributions are also known as negatively-skewed distributions. That’s because there is a long tail in the negative direction on the number line. So in this case peak remains on the right side.
A right-skewed distribution has a long right tail. Right-skewed distributions are also called positive-skew distributions because there is a long tail in the positive direction on the number line. So in this case peak remains on the left side.
In our case it can be see that the data has peak on to the right side and hence it is left skewed. Also it can be seen from the dot plot that Shira has never scored fewer than 2 points and the maximum she has scored in a game is 12 points.
Therefore, the data is skewed to the left and shows that she never scored fewer than 2 points or more than 12 points in a game
