Answer: 40
Step-by-step explanation:
5 * 8 = 40
<span>62.0 inches
The first thing to do is look at a Standard Normal Table to find out how many deviations we need to be from the norm to get 20%. Depending upon the table, you will either be looking for a value of 0.20 or 0.30. The 0.30 is simply 0.50 - 0.20. Use your common sense to determine which value to look for. For instance, in the Standard Normal Table I'm using, a z value of 0 gives me a probability of 0.00000 and a z-value of 4.0 gives me a probability of 0.49997. So I need to look for a probability of 0.30 which is a z-value of approximately 0.84.
Now multiply the z-value by the standard deviation. So
0.84 * 2.4 = 2.016
This value of 2.016 means that only 20% of the population are more than 2.016 inches shorter than the mean. So let's calculate that by subtracting that from the mean, giving:
64 - 2.016 = 61.984.
Rounding to 1 decimal place gives 62.0 inches.</span>
Answer: The cost per pound for bananas is $1.5 per pound.
Step-by-step explanation:
To get this answer you will divide the cost by the amount of bananas you have.
When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.
0 = -(x-2)^2 + 16
(x-2)^2 = 16
x-2 = 16
x-2 = 4
x = 6
This means the ball will hit the ground 6 seconds after Amir threw it.
