slope, rate of change is.
use this formula, to find right of change we can.
input two pairs of coordinates, we must.
use 0, 1 and 5, 4, we will.
4 - 1 / 5 - 0
3 / 5
3/5, the slope is.
hmm.
convert 3/5 to decimal, we must.
multiply both sides by 2, we can.
3 * 2 = 6
5 * 2 = 10
6/10, our new fraction is.
convert to decimal, we must.
6/10 = 0.6
0.6, our slope is.
Using the t-distribution, it is found that the test statistic for the hypotheses test is given by:
<h3>What are the hypotheses tested?</h3>
At the null hypotheses, it i tested if the mean difference remains the same, that is:
At the alternative hypotheses, it is tested if it has decreased, hence:
.
<h3>What is the test statistic?</h3>
The test statistic is given by:
The parameters are:
is the sample mean.
is the value tested at the null hypothesis.
- s is the standard deviation of the sample.
The parameters are given as follows:
.
Hence the test statistic is given by:

Answer:
The owner's profit for a ten-day period is $4675
Step-by-step explanation:
Each day a small business owner sells 200 pizza slices for $1.50 per slice and 85 sandwiches at $3.50 each.
Let's find the revenue.
Revenue = 200($1.50) + 85($3.50)
= $300 + $297.50
Revenue per day = $597.50
Revenue for 10 days = 10($597.50) = $5975
Business expenses per day = $130
Business expenses for 10 days = 10($130) = $1300
Now let's find the profit.
Profit for 10 days = Revenue - Expense
= $5975 - $1300
= $4675
So the owner's profit for a ten-day period is $4675
Answer:
2*(b-6)=8
Explication:
1.divide both sides by 2
b - 6 = 4
2. move the constant to the right and change the sign
b= 4 + 6
3. Calculate
b= 10
