Answer:
The x-coordinates of the points are x = 3 and x = - 8.
Step-by-step explanation:
We have to find the x-coordinates of the points where the graph of equation y = (x - 3)(x + 8) crosses the x-axis.
Now, the x-intercept of a function implies that y = 0 {Because on x-axis, y-value is zero}
Hence, (x - 3)(x + 8) = 0
⇒ (x - 3) = 0 and (x + 8) = 0
⇒ x = 3 and x = - 8
Therefore, the x-coordinates of the points are x = 3 and x = - 8. (Answer)
9,11,13,20
20 -9 = 11
Range: 11 so its not 17
11 + 13 = 24
24/2 = 12
Median: 12 so its not 10
9+ 11 + 13 + 20 = 53
53/4= 13.25
Mean: 13.25 so its not 12
IQR: 6.5 so its not 7 or 12
Answer:
14 cards
Step-by-step explanation:
70 - 15 = 55
55/4 = 13.75
Therefore, the highest number of cards someone is able to get is 14.
