The number is assumed to be x
x of 40% = 56
x * (40/100) = 56
x = 5600 / 40
x = 140
if the washer and dryer cost $790 then you would divide 790 by 2.
then you will get $395
then you add 40 to $395 and will get $435
so the answer is $435
The statement that is correct is E
Answer:
(B) Because the confidence interval includes 0, we don't have convincing evidence that sugar causes faster reading times, on average.
Step-by-step explanation:
Confidence Interval for the population mean difference in reading is basically an interval of range of values where the true population mean difference in reading time can be found with a certain level of confidence.
Mathematically,
Confidence Interval = (Sample mean) ± (Margin of error)
In using confidence interval of population mean difference in reading times for hypothesis testing, if the interval obtained contains a value of 0, it means the population mean difference in reading times can take on a value of 0 and indicate that there isn't enough evidence to conclude that there is a significant difference in the two quantities being compared. (The null hypothesis is true).
If the interval doesn't contain a 0, then it can be concluded that there is enough evidence to conclude that there is significant difference in the two quantities being compared.

If cot θ = 12/5, then tan θ = 5/12.
If sec θ = -13/5, then cos θ = -5/13
For tan θ to be positive while cos θ is negative, the quadrant is 3.
The figure below shows θ graphed as a reference angle in quadrant 3.
Answer:
The statement that θ is in quadrant 4 is FALSE.
