Answer and the Step-by-step explanation : -

1) x(y - 5) = 2

First you gotta open the brackets so then you'll get : -

xy - 5x = 2

Answer : - " since xy is remaining the equation will not linear "

2) y - 2(x + 9) = 0

"y - 2x - 18 = 0 "

"Y = 2x + 18 "

Answer : - "This is linear"

3) 3y + 6(2 - x) = 5

3y + 12 - 6x = 5

3y = 5 - 12 + 6x

3y = 6x - 7

Y = 2x - 7/3

Answer : -This is linear

4) 2(y + x) = 0

2y + 2x = 0

2y = - 2x

y = - x

Answer : - " This is linear "

Answer:

Lawns ---Earnings

1 ----------------- 10

2 ----------------- 20

3 ----------------- 30

5 ----------------- 50

Step-by-step explanation:

Given

Earnings = $10 per lawn

Required

Complete the table

Let y be the earnings for x number of lawns

Since he earns $10 per x lawns, then the expression is:

$y = 10x$

To complete the table, we have the following:

When x = 1

$y = 10 * 1 = 10$

When x = 2

$y = 10 * 2 = 20$

When x = 3

$y = 10 * 3 = 30$

When x = 5

$y = 10 * 5 = 50$

So, the complete table is:

Lawns ---Earnings

1 ----------------- 10

2 ----------------- 20

3 ----------------- 30

5 ----------------- 50

What is thirty five percent of two hundred

Anika [276]

To do this, convert 35% to a decimal, which would be moving the decimal two times to the left which would be 0.35. Then, to find 35% of 200, you would multiply 0.35 and 200 to get your answer: 70

The number of typing errors made by a typist has a Poisson distribution with an average of two errors per page. If more than two

wlad13 [49]

Answer: 0.6767

Step-by-step explanation:

Given : Mean = $\lambda=2$ errors per page

Let X be the number of errors in a particular page.

The formula to calculate the Poisson distribution is given by :_

$P(X=x)=\dfrac{e^{-\lambda}\lambda^x}{x!}$

Now, the probability that a randomly selected page does not need to be retyped is given by :-

$P(X\leq2)=P(0)+P(1)+P(2)\\\\=(\dfrac{e^{-2}2^0}{0!}+\dfrac{e^{-2}2^1}{1!}+\dfrac{e^{-2}2^2}{2!})\\\\=0.135335283237+0.270670566473+0.270670566473\\\\=0.676676416183\approx0.6767$

Hence, the required probability :- 0.6767

Ariana bought 5 dozen pears at $36 per dozen . She discovered that 7 were rotten and she sold the rest at $4.50 each . Calculate

GrogVix [38]

Step-by-step explanation:

1 dozen = 12 pears

12 pears = $36

1 pear = 36/12 = $3

Total Cost of Pears = No. of pears x price of 1 pear

= (5x12) x 3

= 60 x 3

= $180

Sale of Pears = Price per pear x (Total Pears bought - Rotten Pears)

= $4.50 x (5x12-7)

= $4.50 x 53

= $238.50

Profit/Loss = Sale of Pears - Total Cost of Pears

= $238.50 - $180

= $58.50

Ariana made a profit of $58.50.
