Answer: y = -1.4(2.1 - 4.2x)

Step-by-step explanation:

4.2x - 1.4y = 2.1

Firstly you should move 4.2x over (by subtraction) so the new equation is:

-1.4y = 2.1 - 4.2x

Then you want to multiply everything by -1.4 to take it away from the y side. This will bring you to:

y = -1.4(2.1 - 4.2x)

This can be simplified down to

y = -2.94 + 5.88x

or

5.88x -2.94 = y

Answer:D

Step-by-step explanation:

Neither data set has suspected outliers response best describes outliers in the data sets.

Option A is correct.

The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), ​first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

According to question

Reading:

Median = [tex]\frac{7+12}{2}[/tex] = 9.5

[tex]Q_{1}[/tex] = 5 × 25% + 7 × 75% = 6.5

[tex]Q_{3}[/tex] = 14 × 25% + 12 × 75% = 12.5

IQR is the difference between Q3 and Q1

IQR = [tex]Q_{3}[/tex] - [tex]Q_{1}[/tex] = 12.5 - 6.5 = 6

[tex]Q_{1}[/tex] - 1.5 IQR = 6.5 - 1.5 × 6 = -2.5 < Min = 5

[tex]Q_{3}[/tex] + 1.5 IQR = 6.5 + 1.5 × 6 = 15.5 > Max = 15

So no outlier in reading

Video :

[tex]Q_{1}[/tex] = 7 × 75% + 4 × 25% = 6.25

[tex]Q_{3}[/tex] = 21 × 25% + 18 × 75% = 18.75

IQR is the difference between Q3 and Q1.

IQR = [tex]Q_{3}[/tex] - [tex]Q_{1}[/tex] = 18.75 - 6.25 = 12.5

[tex]Q_{1}[/tex] - 1.5 IQR = 6.25 - 1.5 × 12.5 = -12.5 < Min = 1

[tex]Q_{3}[/tex] + 1.5 IQR  = 18.75 + 1.5 × 12.5 = 37.5 > Max = 26

So no outlier in video

So neither data set has suspected outliers.

Option A is correct.

Answer:

D

Step-by-step explanation:

Answer:

a=180-79

a=101

c=83 (vertically opposite angles)

d=c (corresponding angles)

d=83

b=a(corresponding angles)

b=101

Answer: a=101 b=79 c=83 d=97

Step-by-step explanation:

A: angles on a straight line add up to 180° so you would take away 79° from 180° which is 101°.

B: angles on a parallel lines are always the same, you can see that 79 is at the same position as b.

C: opposite angles are always the same so it would still be 83°.

D: d is on other side as c and this would add up to 180° so as we already know that c is 83° you would have to take away 83° from 180° to get d.

The measure of the side length (that is hypotenuse) of the right-angle triangle will be √202 units.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

Let the missing side of this right triangle be х.

Then the measure of the side length (that is hypotenuse) of the right-angle triangle will be

x² = 9² + 11²

x² = 81 + 121

x² = 202

 x = √202

Answer:

The probability of not rolling a 5 AND not spinning a 5 is (5/6)*(4/5)=20/30

Step-by-step explanation:

These are independent events.

The probability of rolling a 5 is 1/6.

The probability of spinning a 5 is 1/5.

The probability of rolling a 5 or spinning a 5 is 1/5+1/6=11/30 but you have to subtract 1/30 because you can roll a 5 and spin a 5 at the same time. Therefore 11/30-1/30=10/30=1/3.

There are 30 outcomes. Roll first then spin to get the following outcomes:

11,12,13,14,15,21,22,23,24,25,31,32,33,34,35,41,42,43,44,45,51,52,53,54,55,61,62,63,64,65

You want to roll a 5 OR spin a 5. How many combinations have a 5 ? 10 combinations have a 5.

(you don't count 55 twice) There are 10 combinations with a 5 out of a possible 30 combinations.

Another way of looking at the problem is the following:What is the probability of NOT rolling a 5 AND NOT spinning a 5 ?

The probability of not rolling a 5 AND not spinning a 5 is (5/6)*(4/5)=20/30. Therefore the probability of rolling a 5 or spinning a 5 is 1-20/30=10/30.

Answer:

k = 24, y = 24x

Step-by-step explanation:

Given x and y are proportional then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition when y = 72, x = 3 , then

72 = 3k ( divide both sides by 3 )

k = 24

y = 24x ← equation of proportion
