Box-and-whisker plots and the five key values used in constructing a box-and-whisker plot. The key values are called a five-number summary, which consists of the minimum, first quartile, median, third quartile, and maximum.
Answer: 8 hours
Step-by-step explanation:
The pay is for 2 weeks which means that she worked for 80 hours.
At 80 hours, the regular income she should make is:
= 80 * 13.15
= $1,052
The total she made from overtime is therefore:
= 1,209.84 - 1,052
= $157.84
When she works overtime, she gets paid at a rate of a time and half. This means she gets:
= 13.15 * 1.5
= $19.73
The hours of overtime she worked is therefore:
= 157.84/19.73
= 8 hours
Answer:
The value of w cannot be a negative number.
Substitution is used to replace the variable l with a value of 20.
The subtraction property of equality is used to isolate the term with the variable w.
Step-by-step explanation:
Answer:
The required y-value is -121.
Step-by-step explanation:
There are several ways in which we could approach this problem. From the two binomial factors (x + 8) and (x - 14), we know that the two roots are x = -8 and x = 14. The axis of symmetry is the vertical line x = 3. This value is halfway between x = -8 and x = 14.
Substituting x = 3 into f(x)= -(x+8)(x-14) results in f(3) = -(11)(-11) = -121.
The vertex is at (3, -121). The required y-value is -121.
Answer:
10²
Step-by-step explanation:
left triangle = 2 × 2 = 4 ÷ 2 = 2²
right triangle = 2 × 4 = 8 8 ÷ 2 = 4²
middle square = 2 × 2 = 4²
2 + 4 + 4 = 10²
