Answer:  z = 2

Step-by-step explanation:

2.4z+1.2z-6.5=0.7

3.6z-6.5=0.7

3.6z=0.7+6.5

3.6z= 7.2

z=7.2/3.6

There is an upper outlier and lower outlier that is 86.875 and -26.875.

An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. In a sense, this definition leaves it up to the analyst (or a consensus process) to decide what will be considered abnormal. Before abnormal observations can be singled out, it is necessary to characterize normal observations.

Descriptive statistics

data=n=14

mean= 30.29

sample standard deviation= 18.35

sample variance = 336.84

minimum= 1

maximum= 52

range=  51

1st quartile

16.25 = median

37.50 = 2nd Quartile.

3rd quartile = 44.50

4th interquartile range = 28.25

mode = 3.00

Lower limit for outlier = Q1-1.5*IQR =16.25-1.5*28.25 =-26.125

Upper limit for outlier = Q3+1.5*IQR =44.50+1.5*28.25 =86.875

Step-by-step explanation:

cause 30in square = 5 multiplied by 6 = 30

Answer:

b = 3

Step-by-step explanation:

We already know that x = 2, so just plug it back into the equation to solve for the variable b.

[tex]b(2(2)+6)=30[/tex]

[tex]b(4+6)=30[/tex]

[tex]10b=30[/tex]

[tex]b=3[/tex]

We can check this by plugging it back in:

[tex]3(2(2)+6)=30[/tex]

[tex]3(10)=30[/tex]

[tex]30=30[/tex]

This is the correct solution :)

The average fraction of students in the two classes who went on the field trip is 11/16

The given parameters are:

Class 1 = 3/4

Class 2 = 5/8

The average is calculated as

Average = 1/2 * (Class 1 + Class 2)

So, we have

Average = 1/2 * (3/4 + 5/8)

Evaluate

Average = 11/16

Hence, the average fraction of students in the two classes who went on the field trip is 11/16

It would cost $70 to buy 40 ft of crown molding.

What is cost explain?

8 ft length costs $14

To find the cost of 1 ft length,

Divide through by 8

8ft/8 length costs $14/8

1ft costs $1.75

Now, to find the cost of 40 ft length

1ft costs $1.75

1 ft x 40 would cost $1.75

40 ft would cost $70

Therefore, it would cost $70 to buy 40 ft of crown molding.

The steps that you should take to approximate the total amount that Gwinnett County must pay teachers for the whole year are:

The approximate amount that is paid to teachers in will be based on the average wages that is paid to teachers in Gwinnett County. You can find this out by conducting an anonymous survey of different levels of teacher salaries in Gwinnett County or you can find it from the relevant Gwinnett County government department.

Then, look for records to show the number of teachers in Gwinnett County.

Multiply these two figures and you will then get the approximate the total amount that Gwinnett County needs to pay its teachers.

If we select -9 in the number line, then we need to add 6. Because 6 is positive, we need to move 6 units to the right of -9, it will give:

-9 + 6 = -3

When we have two values A and B and we want to add them using the number line, the first thing we need to do is select one of these two, and locate it on the number line.

Once we did that, the other number will tell us how many units we need to move to the left (if B is negative) or to the right (if B is positive).

In this case the two numbers are -9 and 6.

If we select -9 in the number line, then we need to add 6. Because 6 is positive, we need to move 6 units to the right of -9, it will give:

-9 + 6 = -3

We will get the exact same thing if we first step on the number 6 on the number line, and then move 9 units to the left, we will got -3.

There are 4 dollar bills are in a 0.28 inch stack.

Given that, the size of a dollar bill is width= 6.6 cm, length=15.6 cm and height= 0.109 mm= 0.109/10 =0.0109 cm.

The volume of the cuboid is the measure of the space occupied within a cuboid. The cuboid is a three-dimensional shape that has length, breadth, and height. If we have a rectangular sheet and we go on stacking such sheets, we will end up getting a shape that has some length, breadth, and height. The formula to find the volume of the cuboid = Length × Width × Height.

Now, the volume of a dollar bill=15.6 × 6.6 × 0.0109

=1.122264 cm³

Conversion of cm³ to cubic inches.

That is, 1.122264×0.0610237=0.06848≈0.07

Now, the number of dollars bills=0.28/0.07
