We found this regression equation for the data to be
f(x) = .003415(2.0399)^x
When x = 14
.003415 (2.0399)^14 ≈ 73.5
It looks like for every x the y is increasing by 1.5x. The closest one is D, because \(200\times 1.5\) is around 415.
You are very welcome!
:P
P(both) is not 195/210
Anytime! Glad to help out users!
Thank you, CPhill! I have been working on them.
Sorry if i'm thinking too basically here. By the way, I'm 11 and don't understand the next parts to this question.
I can answer top 3. P(sister) would be 9/21
P(brother) would be 1/2
P(both) would be 195/210
Excellent, tertre...your LaTex presentations are good...
It seems that as \(x\) increases \(y\) increases by 1.75x or so. Therefore, \(35 \times 1.75=61.25\) and the closest answer choice is B.
C
Thanks, tertre....!!!
Let's see! 220,000 is already plotted in the graph. Lining it up, we see that the line of best fit, at a population of 220K, says the crime index is around 500, or C.
Alright, great!
Oh hehe thanks!
Exponential growth means that as \(x\) grows larger \(y\) gets smaller. Only C works, because all the other options have decimals/fractions under 1 in their parentheses, so the graph gets smaller when \(x\) increases. Again, it's C.
Evaluate this, NSS...I'll check your answer, if you want
3700* e^( .045 * 7 )
Did ya a favor and subscribed to your yt, or at least what I think is your yt, CoolStuff.
Nice, CoolStuff....!!!
Now that I've posted a question I like to ask to have fun, I'll post actual math questions now.
Yep.....can't do anything before we know what the problem is....
Haha! Welcome, by the way.
We just add all the red cars, which is \(32+29+23=84.\) The total number of cars are \(374.\) So, the answer is (D).
This is an exponential function, so for every \(x\), \(y\) increases slowly at first, but then drastically when \(x\) gets bigger. See:
Only B fits the explanation.
I'll just tell you.
Obvious answer: 10
Smart answer: 2+8
See what I did there?
P ( remained for > 6 months l joined in Jan ) =
P ( over 6 months and joined in Jan) 0.024 1
______________________________ = _____ = __ = 20%
P( joined in Jan) 0.12 5
