Answer:
7.25 each or 7.00 if rounded
Step-by-step explanation:
I found a graph with the same problem, so I guess this is the graph to be based on. To find the rate, just determine the slope between any two points along the line. Suppose these points are: (30,10) and (50,20).
Slope = (20 - 10)/(50 - 30) = 1/2
<em>The correct answer should be: the rate of change is 1 cm per 2 weeks, or 1/2.</em>
Answer:
part A 1.68
part B 29.67
Step-by-step explanation:
First you multiply $39.99 dollars and 0.30 = $11.9970 you round this to $12.00
After you apply the discount $39.99 - $12.00 = 27.99
Next you must multiply 27.99*0.06 =1.6794 and round to 1.68 to get tax
Last you add $27.99 and 1.68 to get a total of $29.67 for the headphones
Plz give brainliest i didnt look it up.
Answer:
There is enough evidence to support the claim that the true proportion of monitors with dead pixels is greater than 5%.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 300
p = 5% = 0.05
Alpha, α = 0.05
Number of dead pixels , x = 24
First, we design the null and the alternate hypothesis
This is a one-tailed(right) test.
Formula:
Putting the values, we get,
Now, we calculate the p-value from excel.
P-value = 0.00856
Since the p-value is smaller than the significance level, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.
Conclusion:
Thus, there is enough evidence to support the claim that the true proportion of monitors with dead pixels is greater than 5%.
