12. This may be incorrect. You're sentence is a little chopped up so I can't understand you that well.<span />
Answer:
200r
Step-by-step explanation:
All you have to do is multiply the 10 and 20 to get 200 and then put the r after the 20, so it would look like this 200r
Answer:
The slope of the line passing through (-3, 5) and (5, -3) is:
Slope = undefined
Step-by-step explanation:
Given the points
Here:
(x₁, y₁) = (2, 3)
(x₂, y₂) = (2, -5)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [-5 - 3] / [2 - 2]
= -8 / 0
= undefined
Thus, the slope of the line passing through (-3, 5) and (5, -3) is:
Slope = undefined
You would have to divide $16.76 by 4 to find out how much 1 gallon costs and after that multiply the amount a gallon costs by 7 to get your answer
Answer: f) None of the above
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 5.6ft
Standard deviation r = 1.0ft
Number of samples n = 27
Confidence interval = 90%
z(at 90% confidence) = 1.645
Substituting the values we have;
5.6+/-1.645(1.0/√27)
5.6+/-1.645(0.192)
5.6+/-0.317 ft
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
