Answer:
NO this set is not equivalent
Step-by-step explanation:
Okay the way you find out if a pair of ratios are equal is you would divide the denominator and nominator with each other, so: 13/7 and 9/4. But sense the answer would be in decimal form and cant be simplified this wouldnt be considered equivalent. Also if you divide 7 by 4 you get a different answer than when you do 13 divided 9.
Answer: the credit union loaned out $40000 at 6% and $10000 at 12%
Step-by-step explanation:
Let x represent the amount that the
credit union loaned out at the annual rate of 6%.
Let y represent the amount that the
credit union loaned out at the annual rate of 12%.
credit union loaned out $50,000, part at an annual rate of 6% and the rest at an annual rate of 12%. It means that
x + y = 50000
The interest on $x after 1 year would be
6/100 × x = 0.06x
The interest on $y after 1 year would be
12/100 × y = 0.12y
The collected combined interest was $3,600 that year. It means that
0.06x + 0.12y = 3600- - - - - - - - - 1
Substituting x = 50000 - y into equation 1, it becomes
0.06(50000 - y) + 0.12y = 3600
3000 - 0.06y + 0.12y = 3600
- 0.06y + 0.12y = 3600 - 3000
0.06y = 600
y = 600/0.06
y = $10000
x = 50000 - y = 50000 - 10000
x = $40000
Answer:
Are you ok? Do you need the call 911, or is this an actual question?
Step-by-step explanation:
<span>for that, what you need is a calculator... like say a TI(texas instruments) 83 or 83plus or higher, will do regressions, if you have an android device like a phone or tablet, you can also get an app from the play store "Andie's graph", is a TI calculator emulator, it works just like the calculator itself, you'd only need the ROM
</span><span>that said, you can also use some online calculators for that.
</span>
<span>I could give you a direct link to one, but this site has issues with links, if you do a quick search in google for "keisan exponential regression calculator", it should be the first link, is from the Casio site.
</span>
<span>you could do regressions in a spreadsheet as well.... you could check online for an "addin" or "extension", if you use MS Excel, pretty sure there are some addins for regressions.
</span>
if I recall correctly, Excel does regressions natively, but the addins are just frontends, is all, just some added interfacing.
anyhow, if you have an Android device Andie Graph works peachy, I have an 83plus, 84, 86 in it, they all work just like my old TI83plus.
there's also an app in the play store called Graph89, is an emulator for a TI89, the same you need a tiny little file, and texas instruments provides them, have also, works peachy too.
20t^2+9t-20 is the answer
