NEED HELP IMMEDIATELY. 50 POINTS TO THE BEST ANSWER.

Reil [10]

Answer:

See below

Step-by-step explanation:

r=0 means there is zero correlation between the independent and dependent variables. Most likely, some other regression model will help to bring the value of r closer to -1 or 1 to show a strong correlation.

Because of a virus introduced into a bacterial culture, the population of the bacteria decreasedfrom 3000 to 1000 in 50 minutes.

Mamont248 [21]

Answer:

208

Step-by-step explanation:

Given that;

Given that;

y= a(1 - b)^t

Where;

wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.

To obtain the constant b,

y= ae^-bt

Substituting values;

1000 = 3000 e^-b(50)

1000/3000 = e^b(50)

0.33 = e^b-(50)

ln (0.33) = ln(e^b(-50))

-1.1 = -50b

b= 1.1/50

b= 0.022

After two hours or 120 minutes;

y= 3000(1 - 0.022)^120

y= 207.8661772

y= 208

Use the euclidean algorithm to find

kvasek [131]

A)
$18=1\cdot12+6$
$12=2\cdot6+0$
$\implies\mathrm{gcd}(12,18)=6$

b)
$201=1\cdot111+90$
$111=1\cdot90+21$
$90=4\cdot21+6$
$21=3\cdot6+3$
$6=2\cdot3+0$
$\implies\mathrm{gcd}(111,201)=3$

c)
$1331=1\cdot1001+330$
$1001=3\cdot330+11$
$330=30\cdot11+0$
$\implies\mathrm{gcd}(1001,1331)=11$

d)
$54321=4\cdot12345+4941$
$12345=2\cdot4941+2463$
$4941=2\cdot2463+15$
$2463=164\cdot15+3$
$15=5\cdot3+0$
$\implies\mathrm{gcd}(12345,54321)=3$

e)
$5040=5\cdot1000+40$
$1000=25\cdot40+0$
$\implies\mathrm{gcd}(1000,5040)=40$

f)
$9888=1\cdot6060+3828$
$6060=1\cdot3828+2232$
$3828=1\cdot2232+1596$
$2232=1\cdot1596+636$
$1596=2\cdot636+324$
$636=1\cdot324+312$
$324=1\cdot312+12$
$312=26\cdot12+0$
$\implies\mathrm{gcd}(9888,6060)=12$

Answer:

Step-by-step explanation:

$\frac{5x - 2}{4}+\frac{1}{2}=\frac{3y+2}{2}$

Multiply the equation by 4

$4*\frac{5x - 2}{4}+4*\frac{1}{2}=4*\frac{3y+2}{2}\\$

5x - 2 + 2 = 2*(3y + 2)

5x +0 = 2*3y + 2*2

5x = 6y + 4

5x - 6y = 4 --------------------(I)

$\frac{7y+3}{3}=\frac{x}{2}+\frac{7}{3}\\$

Multiply the equation by 6

$6*\frac{7y+3}{3}=6*\frac{x}{2}+6*\frac{7}{3}\\$

2*(7y + 3) = 3x + 2*7

14y + 6 = 3x + 14

14y = 3x + 14 - 6

14y = 3x + 8

-3x + 14y = 8 ------------------------(II)

Multiply equation (I) by 3 and equation (II) by 5 and then add

(I)*3 15x - 18y = 12

(II)*5 <u>-15x + 70y = 40</u> {Now add}

52y = 52

y = 52/52

y = 1

Substitute y =1 in equation (I)

5x - 6*1 = 4

5x - 6 = 4

5x = 4 +6

5x = 10

x = 10/5

x = 2
