S sold by colour/Percent /1800 order/ 1200 order

Red / 25% / 450 / 300
Blue/ 15% / 270 / 180
Green/ 12% / 216 / 144
Yellow/ 5% / 90 / 60
Purple/ 7.5% / 135 / 90
White / 37.5% / 675 / 450

You see first I found the percentage sold by colour then calculated each colour by percentage based on 1800 order then same for 1200 order.
Hope it's correct, I'd appreciate if you let me know. And may be you give the brainliest for this.. :))

If f (n)(0) = (n + 1)! for n = 0, 1, 2, , find the taylor series at a=0 for f.

Pie

Given that $f^{(n)}(0)=(n+1)!$ , we have for $f(x)$ the Taylor series expansion about 0 as

$f(x)=\displaystyle\sum_{n=0}^\infty\frac{(n+1)!}{n!}x^n=\sum_{n=0}^\infty(n+1)x^n$

Replace $n+1$ with $n$ , so that the series is equivalent to

$f(x)=\displaystyle\sum_{n=1}^\infty nx^{n-1}$

and notice that

$\displaystyle\frac{\mathrm d}{\mathrm dx}\sum_{n=0}^\infty x^n=\sum_{n=1}^\infty nx^{n-1}$

Recall that for $|x|$ , we have

$\displaystyle\sum_{n=0}^\infty x^n=\frac1{1-x}$

which means

$f(x)=\displaystyle\sum_{n=1}^\infty nx^{n-1}=\frac{\mathrm d}{\mathrm dx}\frac1{1-x}$
$\implies f(x)=\dfrac1{(1-x)^2}$

Samuel made a list of his test scores: 88, 100, 92, 80, 85, 94, and 90. What is the lowest test score he can get on his next tes

yulyashka [42]

Answer:

he needs to get a 91 to have a mean score of 90

Step-by-step explanation:

add up all the known scores to get 629

let 's' = lowest test score

(629 + s) ÷ 8 = 90 [we divide by 8 because there are 7 known and 1 unknown score)

cross-multiply to get:

629 + s = 720

s = 720-629

s = 91

Please help with this 2+4(5-8). step by step

igor_vitrenko [27]

NAMASTE

HERE IS YOUR ANSWER:

2+4(5-8)
We know, the BODMAS (bar, order, multiply, add, subtract) rule. so we will solve it as follows:

➡2+4(-3) (✔ 5-8= -3)

➡2+(-12) (✔ 4(-3)= -12)

➡2-12 (✔ +(-12) = -12)

➡ $\boxed{-10}$

Compare 2 x 10^4 and 8 x 10^3

agasfer [191]

2* 10^4 would be bigger than 8* 10^3.

10^4 = 10000*2=20000
10^3 = 1000*8=8000
