Answer:
$386.9
Step-by-step explanation:
Given that current grocery costs are $500 and he want to reduce 5% every month
We can create a geometric progression with a = 500 and common ratio(r) = 0.95
because every time we reduce 5% we actually make the actual cost as 95%
Now we should find n=6
The allotment is $386.9
Answer:
The mean is 9.5 and the median is 6.5.
Step-by-step explanation:
<em>To find the mean:</em>
Add all numbers given.
9+8+5+3+37+8+4+2= 76
Then divide by the amount of numbers (8).
76/8= 9.5
<em>To find the median:</em>
Re-arrange the order of the numbers from least to greatest.
2, 3, 4, 5, 8, 8, 9, 37
Count towards the middle. If there is no exact middle (like this equation), then take the two middle numbers and add them.
5+8= 13
After, divide by two since there are two numbers being added.
13/2= 6.5
Mean is 27.4
Median is 22
Range is 27

We conclude that the interval in which the function decreases is (1.5, 3]
<h3>
In which interval is the ball's height decreasing?</h3>
The ball is decreasing when the graph, reading from left to right, is going downwards.
Particularly, in this parabola that opens downwards, the graph will decrease after the vertex.
And we can see that the vertex is at x = 1.5
And we also see that the graph of the function ends at x = 3.
Then we conclude that the interval in which the function decreases is (1.5, 3]
