Solve for y 2x-5y=-12

Darina [25.2K]

To solve for y, we must isolate it

$2x - 5y = -12$
$2x + 12 = 5y$
$\frac{2x + 12}{5} = y$

A fair six-sided die, with sides numbered 1 through 6, will be rolled a total of 15 times. Let x¯1 represent the average of the

Anna35 [415]

Answer:

option B

Step-by-step explanation:

$P(x =x) [{\frac{1}{6} ;x =1,2,3...6]$

$E (x) = \frac{6+1}{2} =\frac{7}{2} =3.5\\\\E(x)=3.5$

Given random experiment of tossing of 6 sided dice is follow above distribution

Therefore, suppose x₁, x₂ ...x₁₀ are 10 independent and indentical random variable which represent first 10 rolls

Average of first 10 rows equals

$\bar x_1 =\frac{ \sum ^{10}_{i=1}xi}{10}$

$E(\bar x_1)=\frac{ \sum ^{10}_{i=1}E(x_1)}{10} \\\\=\frac{10(3.5)}{10} \\\\=3.5\\\\E(\bar x_1) = 3.5----(1)$

now suppose ,

x₁₁,x₁₂, ...x₁₅ are 5 independent and identical random variable which represent last 5 roll

average of last 5 roll is

$E(\bar x_2)= \frac{ \sum ^{5}_{i=1}xi}{5} \\\\= \frac{5 \times(3.5)}{5} \\\\=3.5$

Therefore, $\bar x_1 - \bar x_2$

3.5 - 3.5 = 0

The length of a swimming poollane

Hunter-Best [27]

Answer:

x²+5x - 150 = 0

Step-by-step explanation:

Let the length be y and width be x

If the length of a swimming pool is 10 more than 2 times the width, then;

y = 2x+10 ...1

Since the Area is 300m²

A = xy

300 = xy .... 2

Substitute 1 into 2

300 = x(2x+10)

300 = 2x²+10x

Rearrange

2x²+10x - 300 = 0

Divide through by 2

x²+5x - 150 = 0

This gives the required quadratic expression
