A lumber yard has scrap wood for sale. One employee recorded the measurements for the lengths of 50 different wood boards. The median length was recorded as 47.78 inches and the IQR was recorded as 14.54 inches. Someone discovers the measuring tape used started at 5 inches instead of 0. This means that each piece of wood is actually 5 inches shorter than the value recorded by the employee. What is the updated IQR

Answers

Answer:

The updated IQR is 14.54.

Step-by-step explanation:

The interquartile range is given by the difference between the 75th percentile(value that is greater than 75% of the measures) and the 25th percentile.

This means that each piece of wood is actually 5 inches shorter than the value recorded by the employee.

This means that the length of each wood is less than 5. However, the difference between the 75th percentile and the 25th percentile will stay the same, since both were subtracted by 5.

The updated IQR is 14.54.

The updated IQR is 14.54.

Interquartile range:The interquartile range should be provided by the difference between the 75th percentile and the 25th percentile.Since IQR was recorded as 14.54 inches. So the updated IQR is 14.54.

There were 4 hobos that arrived in town looking for work. They met with a business owner who said he could pay them for 200 hours of work. However, there was a catch. They could divide up the work anyway they wanted, but each hobo had to work the same number of days as he/she worked hours in 1 day. For example, If a hobo worked 8 hours a day, he/she had to work for 8 days. The other catch is that the laziest hobo of all did the negotiations with the business owner and then went back to present the plan to his/her pals.

The question is how many hours a day did each hobo work?

(9x-4)°

(3x+ 14)°

solve for x=

don’t understand how to find the answer

Answers

Answer:

x=3

Step-by-step explanation:

Simplifying

9x + -4 = 3x + 14

Reorder the terms:

-4 + 9x = 3x + 14

Reorder the terms:

-4 + 9x = 14 + 3x

Solving

-4 + 9x = 14 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-4 + 9x + -3x = 14 + 3x + -3x

Combine like terms: 9x + -3x = 6x

-4 + 6x = 14 + 3x + -3x

Combine like terms: 3x + -3x = 0

-4 + 6x = 14 + 0

-4 + 6x = 14

Add '4' to each side of the equation.

-4 + 4 + 6x = 14 + 4

Combine like terms: -4 + 4 = 0

0 + 6x = 14 + 4

6x = 14 + 4

Combine like terms: 14 + 4 = 18

6x = 18

Divide each side by '6'.

x = 3

Simplifying

x = 3

Answer:

x = 3

Explanation:

Write your equation

(3x + 14) = (9x - 4)

Subtract 9x from both sides

3x + 14 − 9x = 9x − 4 − 9x

−6x + 14 = −4

Subtract 14 from both sides

−6x + 14 − 14 = −4 − 14

−6x = −18

Divide both sides by -6

−6x / -6 = −18 / -6

x = 3

Solve for x in the diagram below.

Answers

Answer:

x = 20

Step-by-step explanation:

x + 2x + (x + 10) = 90° (right angle)

x + 2x + x + 10 = 90

Add like terms

4x + 10 = 90

4x = 90 - 10 (substraction property of equality)

4x = 80

x = 80/4 (division property of equality)

x = 20

11. If you want to enlarge a square with area 36 square inches
by a factor of 3, what would be its new perimeter?

a. 18 inches
b. 24 inches
c. 324 inches
d. 8 inches
e. 72 inches

Answers

Answer:

e. 72 inches

Step-by-step explanation:

Well, firstly to find the lengths of the sides, we would have to find the square root of 36 (which is 6, as 6x6=36).

Now, if we enlarge the square by SF 3, the new side lengths would be 6x3=18 inches. That is only one side.

Now we know the length of one side, we can do 18x4 (because as we all know, squares have 4 sides) to find the perimeter.

18x4=72 inches. This means the answer is option e.
