Answer:
D. 40
Step-by-step explanation:
Interquartile range is the difference between the upper quartile value (Q3) and the lower quartile value (Q1).
In a box plot, Q1 is located at the beginning of the edge of the rectangular box from our left, while the Q3 is located at the end of the edge of the rectangular box to our right.
Interquartile range for City A = 70 - 40 = 30
Interquartile range for City B = 80 - 40
Therefore, city B has greater variability. The interquartile range is 40.
Step-by-step explanation:
By the Distributive Property,
2/5 * (15x - 10)
= (2/5)(15x) + (2/5)(-10)
= 6x - 4.
Answer:
x = 13
Step-by-step explanation:
54 divided by (13 + 5) = 3
Area of a trapezoid = ½(a + b)h, where a and b are the lengths of the parallel sides and h is its height.
<span>From your information 20 = ½(2z + 3 + 6z – 1)z = ½(8z + 2)z = z(4z + 1) </span>
<span>Solve 20 = 4z² + z which is 0 = 4z² + z – 20 using the quadratic formula

We can find the distance that they are at at 10 seconds by multiplying their velocity.
Han - 40 feet away from Clare.
Clare - -50 feet away from Han.
Han and Clare would be -10 feet away from the meeting place at -10 feet.
