Answer:
The correct option is A,3875 passengers
Step-by-step explanation:
The curve of best fit for the date y=-5x^2+60x+3715
For April which month 4 which means that x is 4
By substituting 4 for x in the equation we can determine y, the number of passengers that arrived on flights at the airport is determined thus.
y=-5*4^2+(60*4)+3715
y=-5*16+240+3715
y=-80+240+3715=3875
The number of passengers that arrived by flights in April, month 4 is 3875
Answer:
<em>The total price of the CD is $14.18</em>
Step-by-step explanation:
<u>Percentages
</u>
We can compute additive or subtractive percentages by using these formulas. If we have a number X and want to increase it by Y%, then the increase is xY/100. Thus the new value for the number is x+xY/100 or equivalently
If we want to decrease by Z%, the new value is
The regular price for a CD is X=$15. The CD is Z=10% off, so the sale price is
But we have to add the tax of Y=5%, so the final value is
The total price of the CD is $14.18
Answer:
Option C. The real effect is 0.1
Step-by-step explanation:
The complete question is
You are interested in the psychological implications of high SES. You read a paper that claims that higher social class people behave more unethically. The paper reports a significant difference in the propensity of high and low SES people behaving unethically. The significance level of this study was 0.05, the ratio of true to false effects in this field is 0.35, but the author was anxious to issue a press release and prepare his TED talk, so power is low, at 0.1. The probability that this study reports a real effect is
A. 0.58
B. 0.95
C. 0.1
D. 0.35
E. 0.41
Solution
Ratio of true to false effects i.e T/F = 0.35
The power of the study indicates the real effect of the study and hence despite the true/false ration being 0.35 and the significance level of study is 0.05, the real effect of the study would be 0.1
Hence option C is correct
Answer:
start by checking that it's a linear relationship that's occurring by having a look at the difference in our X in each step against the difference in our Y in each step.
Step-by-step explanation:
Answer: 3 feet
Step-by-step explanation: The area of a rectangular garden can be represented by the function
f(x) = x(2x + 5)
Find the area if the length, x, is 3 feet.
