First step when finding the mean is to add all the values together
7 + -9 + 6 + -10 + -13 + -5
To make this easier, first add all the positive numbers 7 + 6 = 13
Then add (basically take away) the minus values one by one
13 - 9 = 4
4 - 10 = -6
-6 - 13 = -19
-19 - 5 = -24
Next step is to divide this total by the number of values there were
In this case, there were 6 values
-24 / 6 = -4
D. -4
If the coefficient of x^2 is negative, the graph will be n shaped and curve down instead of like a u shape if it was positive. If the vertex is below the x axis and curves down, it won’t pass the x axis, Tia is right.
Answer:
The number of quarters Josie has in her collection of 92 coins 28 quarters
Step-by-step explanation:
The given information are
The total number of coins Josie has = 92
Let the number of quarters she has = x
Therefore, 92 = 8 + 3×x
8 + 3×x = 92
3×x = 92 - 8 = 84
3×x = 84
x = 84/3 = 28
x = 28
The number of quarters Josie has in her collection of 92 coins = 28 quarters.
Answer:
726
Step-by-step explanation:
Here p = k / q², and 24 = k / 121, or k = 2904
Then p = 2904 / q²
If q = 2, p = 2904 /4 = 726
