1 answer:

8 0

Boys : Girls
9 : 10

-------------------------------------------
Find total parts :
-------------------------------------------
Total Parts = 9 + 10 = 19

-------------------------------------------
Find 1 Part :
-------------------------------------------
19 parts = 2622
1 part = 2622 ÷ 9
1 part = 138

-------------------------------------------
Find 10 parts (girls) :
-------------------------------------------
1 part = 138
10 parts = 138 x 10
10 parts = 1380

Answer:

(a) 74553

(b) 172120

Step-by-step explanation:

Given

$y = \frac{340110}{1 + 377e^{-0.259t}}$

Solving (a): 1998

Year 1998 means that:

$t =1998 - 1980$

$t =18$

So, we have:

$y = \frac{340110}{1 + 377e^{-0.259*18}}$

$y = \frac{340110}{1 + 377e^{-4.662}}$

$y = \frac{340110}{1 + 3.562}$

$y = \frac{340110}{4.562}$

$y = 74553$ --- approximated

Solving (b): 2003

Year 2003 means that:

$t = 2003 - 1980$

$t =23$

So, we have:

$y = \frac{340110}{1 + 377e^{-0.259*23}}$

$y = \frac{340110}{1 + 377e^{-5.957}}$

$y = \frac{340110}{1 + 0.976}$

$y = \frac{340110}{1.976}$

$y = 172120$ --- approximated

Solving (c): 2006

Year 2006 means that:

$t = 2006 - 1980$

$t =26$

So, we have:

$y = \frac{340110}{1 + 377e^{-0.259*26}}$

$y = \frac{340110}{1 + 377e^{-6.734}}$

$y = \frac{340110}{1 + 0.4485}$

$y = \frac{340110}{1.4485}$

$y = 234802$ --- approximated

Evaluate the expression: –(31 + 2) + 72 – (–5)2.

Rudiy27

Answer:

Step-by-step explanation:

Order of operations rules require that we do any work inside parentheses first. Thus,

–(31 + 2) + 72 – (–5)^2

becomes:

-33 + 72 - 25, or

Important: Please use " ^ " to denote exponentiation; (-5)2 is incorrect, whereas (-5)^2 or (-5)² is correct.
