Wow such a hard question but I think it might be -8
Answer:
The answer is s^26/pq59
Step-by-step explanation:
The mean is the same thing as the average, so just add all of the numbers up and divide the total number of numbers.
(13 + 14 + 14 + 16 + 16 + 16 + 16 + 18 + 19)/10 = 16
Given:
4 large oranges @ 0.75 each
8 small oranges @ 0.50 each
total amount paid: 7.49 including sales tax.
4(0.75) = 3.00
8(0.50) = 4.00
3 + 4 = 7
7 + t = 7.49
t = 7.49 - 7
t = 0.49 total amount of tax paid.
0.49/7 = 0.07 sales tax rate
the sales tax rate is 7%
4(0.75) + 8(0.5) = 7
7 x 0.07 = 0.49
7 + 0.49 = 7.49
Answer:
y = 10 + 5x
Step-by-step explanation:
The question seem incomplete as the question requirement is not stated.
However, I'll solve for the equation and also plot the graph that illustrates the equation.
From the question, we have the following.
Base Amount = 10
Additional = 5 (weekly)
Let y represents her savings at any given weeks and x represents the number of weeks
y is calculated using
y = Base Amount + Additional * weeks
y = 10 + 5 * x
y = 10 + 5x
Next, it to plot the graph.
Take x = 0
y = 10 + 5 * 0
y = 10 + 0
y = 10
Take x = 3
y = 10 + 5 * 3
y = 10 + 15
y = 25
So, the graph must pass through
(0,10) and (3,25)
