We are given that popularity of television is inversely proportional to its cost.
let us say popularity of television is represented by "P" and cost of television by "T".
We will use a constant "k" to convert the proportionality sign to equal to (=) sign.
Thus forming the equation :
We are given that 15 customers buy a television that cost $1500.
plugging P=15 and T=1500, finding k,
k=15*1500 = 22500
Next we have to find how many customers would buy a television that costs $2500, so here k=22500 and T=2500, plugging this in the equation we have ,
P=9
So there will be 9 customers that buy a television which costs $2500.
Answer:
The value of test statistic is -2.
Step-by-step explanation:
The following information is missing in the question.
The population mean is 12 minutes.
We are given the following in the question:
Population mean, μ = 12 minutes
Sample mean, = 8 minutes
Sample size, n = 36
Population standard deviation, σ = 12 minutes
Formula:
Putting all the values, we have
The value of test statistic is -2.
Answer:
Step-by-step explanation:
To derive the function rule in slope-intercept form, , we need to find the slope, m, and the y-intercept, b, of the graph given.
Using two points on the line, (-1, 2) and (0, -2), find slope (m) as shown below:
m = -4
The line intercepts the y-axis at y = -2, therefore the y-intercept, b, = -2.
Substitute m = -4, and b = -2 into .
The function rule in slope-intercept form would be:
