Answer:

Length = 11 1/3 ft; Width = 4 2/3 ft

Step-by-step explanation:

First question:

The length is 2 more than twice the width, so

L = 2W + 2

Second question:

2L + 2W = 32

L = 2W + 2

Since the second equation is already solved for L, we can use the substitution method. Replace L of the first equation with 2W + 2, and solve for W.

2L + 2W = 32

2(2W + 2) + 2W = 32

4W + 4 + 2W = 32

6W = 28

W = 28/6 = 14/3 = 4 2/3

L = 2W + 2 = 2(14/3) + 2 = 28/3 + 6/3 = 34/3 = 11 1/3

L = 11 1/3

W = 4 2/3

Answer: Length = 11 1/3 ft; Width = 4 2/3 ft

Choose the equations in which w = 100 makes the equation true.
A. 0.54 ÷ w = 0.0054
B. 4,086 ÷ w = 4.086
C. 362.7 ÷ w = 3.627
D. 5.3 ÷ w = 0.0053
E. 21.9 ÷ w = 0.219

Patty's Pavers has determined that a paver measuring 5 inches long has a z-score of +1 and a paver measuring 5.25 inches long has a z-score of +2.

Hi! I need Help!
What is the mean length of the pavers produced at Patty's Pavers?

4.25 inches
5.25 inches
4.75 inches
5.75 inches

Thank you!

Answers

Answer:

4.75

Step-by-step explanation: given x=5 inches Z-score =1 let 'X' be the variable in normal distribution z=+1 when x=5 inches.

The mean length of the pavers produced at Patty's Pavers is 4.75 inches. Thus, the correct option is C.

What is Z-score?

A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,

[tex]Z = \dfrac{X- \mu}{\sigma}[/tex]

Where Z is the Z-score,

X is the data point,

μ is the mean and σ is the standard variable.

The Z-score of +1 is,

(x-μ)/σ = 1

(5-μ)/σ = 1

5 - μ = σ

The Z-score of +2 is,

(5.25-μ)/σ = 2

(5.25 - μ)/σ = 2

5.25 - μ = 2σ

Substitute the value of the 'σ', therefore, standard deviation from the above,

5.25 - μ = 2(5 - μ)

5.25 - μ = 10 - 2μ

5.25 - 10 = -2μ + μ

μ = 4.75

Hence, the mean length of the pavers produced at Patty's Pavers is 4.75 inches. Thus, the correct option is C.

IM TIMED Which detail best supports the inference that James Watt could not have made the improvement to his steam engine without the assistance of Matthew Boulton? The Steam Engine James Watt, who secured the position as a maker of scientific instruments in the University of Glasgow, proposed an idea for improving the existing steam engine, which was used for pumping mines. For a long time, owing to a lack of money, he had difficulty in establishing the merits of his improvements. Finally, he formed a partnership with Matthew Boulton, a wealthy and energetic man who lived at Birmingham, England. They began the manufacture of steam engines at Birmingham, under the firm name of Boulton and Watt. This partnership was very successful. Watt supplied the inventions; Boulton furnished the money and attended to the business. Before the time of Watt, the steam engine was exclusively a steam pumpslow and wasteful of fuel. Watt made it a quick, powerful, and efficient engine, requiring only a fourth as much fuel as before. Under his first patent, the engine was still used only as a steam pump, but his later improvements adapted it for driving stationary machinery of all kinds. The commercial success of his engine was soon fully established. instruct the planets in what orbs the sun, come eran los guarnes? Is all squares are quadrilaterals?
