Answer:
The more effective way for this data set is the mean.
Step-by-step explanation:
The median required arranging the numbers in an descending-to-ascending order, and it is also preferred if the quantity of the numbers to be an odd number.
In this case, we have repeated numbers, and the quantity is even, which makes finding the median difficult.
Answer:
<em>D = 41</em>
Step-by-step explanation:
y = ax² + bx + c
The discriminant D = b² - 4ac tells the types of roots the equation has.
If D < 0 , then quadratic equation has no real roots, has two imaginary roots.
If D = 0 , then quadratic equation has one real root.
If D > 0 , then quadratic equation has two distinct real roots.
~~~~~~~~~~~~
x² + 5x - 4
a = 1, b = 5, c = - 4
<em>D </em>= 5² - 4(1)(- 4) = 25 + 16 =<em> 41</em>
Answer:

Answer:
12x-15
Step-by-step explanation:
Let
x ---> total hours worked this week
we know that
To find out how much money Sunny earned this week , multiply the total hours worked by the rate of $12 per hour and subtract $15 for a late delivery
