Answer:
That's alot of words, kinda hard to understand
Answer:
The domain is the input value of x, which can be any real number.
There is no inequality.
Set notation x | E R. ( all real nUmbers)
Interval. Oration (-infinity, infinity)
Range: set x to 0 and solve:
3(0)^2 + 2 = 2
The lowest value is 2 and goes to infinity.
Inequality is >=
Set notation Y | >= 2
Interval notation : [2, infinity)
End behavior they both go to infinity .
R + d = 1750
r = d + 450
d + 450 + d = 1750
2d + 450 = 1750
2d = 1750 - 450
2d = 1300
d = 1300/2
d = 650 <=== what Dustin pays
r = d + 450
r = 650 + 450
r = 1100 ...Robert pays 1100
Answer:
The margin of error (M.E) = 3.51
Step-by-step explanation:
<u>Explanation</u>:-
Given data a large school district in Connecticut wants to estimate the average SAT score of this year’s graduating class.
The district takes a simple random sample of 100 seniors.
The sample size 'n' = 100
given data the sample mean is 510 and the population standard deviation for SAT scores is known to be 75.
mean of the sample = 510
population standard deviation σ = 75.
Given data they want an interval that "likely" contains the true mean, where "likely" means "the procedure has a 68% success rate".
level of significance = 68% =0.68
Z-score of 68% of level of significance = 0.468
<u>Margin of error</u>:-
The margin of error of at 68% of confidence intervals.
Margin of error = 3.51
<u>Conclusion</u>:-
Margin of error = 3.51 at 68% of confidence interval
Answer:
A
Step-by-step explanation:
I agree with Katie because number is legs is directly proportional to the number of ants.
1 ant has 6 legs.
So, 2 ants have 6 *2 = 12
3 ants have 6*3 = 18
