Answer:
Step-by-step explanation:
We can use exponent rules to try and simplify this expression down.
Exponent rules tell us that 
.
This means that since we have the same base on both terms (7 and 7), we can add the exponents to get a simplified expression.
So our simplified expression is 
.
Hope this helped!
Right now that equation is a function of time, h(t), height with respect to time. If the baseball is on the ground, it has no height. In other words, its height = 0. So if we set the equation equal to 0 and solve for t, time, that will tell us the time that the ball had a height of 0. If you plug those numbers into the quadratic formula, which is the best and most efficient way to factor a quadratic, you will get that the times are -.0615528128 and 4.061552813 seconds. The 2 things in math that will never EVER be negative are time and distance/length. So we know that the ball will not hit the ground at -.062 seconds. Therefore, it hits the ground 4.06 seconds after it was hit.
MEDIAN:
9 (middle)
MEAN:
(12 + 16 + 10 + 9 + 20 + 11 + 20) / 7 = 14
RANGE:
Highest value: 20
Lowest value: 9
Range: 20 - 9 = 11
INTERQUARTILE RANGE:
First quartile: 16 (It is between 12 and 10)
Third quartile: 11 (It is between 20 and 20)
Interquartile range: 16 - 11 = 5

Let h represent Kate's height at birth. Then: 142 cm = 3h - 2 cm.
Combining like terms: 144 cm = 3h, and h = 48 cm.
Kate's height at birth was 48 cm.
