y= 11 + 4x

3x +2y = 0

Put the first equation into the second one. (replace the value of y)

3x +2 (11 + 4x) = 0

Solve for x:

3x + 22 + 8x = 0

3x+8x = -22

11x = -22

x = -22/11

x = -2

Replace x=-2 in the first equation and solve for y

y= 11 + 4 (-2)

y= 11-8

y= 3

Solution:

x= -2 , y=3

Let's define:

x: pairs of shoes of Shanice

y: pairs of shoes of Ron

Shanice has 4 times as much many pairs of shoes as does her brother Ron, means:

x = 4y (eq. 1)

If Shanice gives Ron 12 pairs of shoes, she will have twice as many pairs of shoes as Ron does, means:

x - 12 = 2y (eq. 2)

Replacing equation 1 into equation 2:

4y - 12 = 2y

4y - 2y = 12

2y = 12

y = 12/2

y = 6

and

x = 4*6 = 24

After she gives Ron the shoes, she will have left 24-12 = 12 pairs of shoes

It is to be noted that the slope of the line is 5/2. This means that 5 mm of rain falls every 2 hours. See the calculation below.

In general, the slope of a line indicates its gradient and direction. The slope of a straight line between two locations, say (x₁,y₁) and (x₂,y₂), may be simply calculated by subtracting the coordinates of the places. The slope is often denoted by the letter 'm.'

To find the slope of the line in the graph, we use the following equation:

m = [y₂ - y₁]/[x₂-x₁]

Where (x1,y1) = coordinates of the first point in the line; and

(x₂,y₂) = coordinates of the second point in the line

Given that the points (2, 5) from the graph is (x₁, y₁) and the point on graph (4, 10) are (x₂,y₂) Hence,

m = [10-5]/[4-2]

The slope (m) = 5/2

The price of one adult ticket is $9 and the price of child ticket is $8

First day of ticket sales the school sold 4 adult tickets and 9 child tickets for a total of $108

Consider the price of adult ticket as x and child ticket as y

Then the equation will be

4x+9y = 108

Similarly the school took in $114 on the second day by selling 10 adult tickets and 3 child tickets

10x+3y = 114

Here we have to use the elimination method

Multiply the first equation by 10 and second equation by 4

40x+90y = 1080

40x+12y = 456

Subtract the equation 2 from equation 1

90y-12y = 1080-456

78y = 624

y = 624/78

y = $8

Substitute the value of y in any equation

10x+3y =114

10x+3×8 =114

10x +24 =114

10x = 90

x = 90/10

x = $9

Hence, the price of one adult ticket is $9 and the price of child ticket is $8

Answer

11) a > 3

12) b > (2/3)

Explanation

11) a - 15 > -4 (-6 + 3a)

a - 15 > 24 - 12a

a + 12a > 24 + 15

13a > 39

Divide both sides by 13

(13a/13) > (39/13)

a > 3

In graphing inequality equations, the first thing to note is that whenever the equation to be graphed has (< or >), the circle at the beginning of the arrow is usually unshaded.

But whenever the inequality has either (≤ or ≥), the circle at the beginning of the arrow will be shaded.

Then, the direction of the graph depends on the direction of the inequality sign, for example, the answer here says a is greater than 3. So, the graph will start with an unshaded circle and cover the numbers greater than 3.

12) 3 (6b - 2) > (8 - 3b)

18b - 6 > 8 - 3b

18b + 3b > 8 + 6

21b > 14

Divide both sides by 21

(21b/21) > (14/21)

b > (2/3)

This answer is similar to that of number 11. For the graph, it will start with an unshaded circle and move towards the numbers greater than (2/3)

P (positive | disease) = 93.9% = 0.939

P (positive | no disease) = 4.1% = 0.041

P (no disease) = 100% - 3.8% = 96.2% = 0.962

The correlation could be positive, meaning both variables move in the same direction,

If it is negative, meaning that when one variable's value increases, the other variables' values decrease.

Since the correlation between the 2 variables is -16

Since -16 is a negative value

Then The answer should be

There is a weak negative association between variables
