Length= y in.
Width= (y-6) in.
Perimeter = 2(L*W)
Perimeter=2L+2W
68in.=2(y)+2(y-6)
68=2y+2y-12
68=4y-12
68+12=4y
4y=80
y=20
Length= 20 inches, width =14 inches

To answer let the length of the rectangle be represented by L. With the condition from the problem, the width is L - 6. The perimeter of the rectangle is twice the sum of the length and width. With the given values, the equation becomes,
                                  P = 2L + 2W
                                 68 in = 2L + 2(L - 6)
The value of L from the equation is 20 inches. Therefore, the width is equal to 14 inches.

Investigate the link between Pascal's triangle and 2 and its powers
lina2011 [118]

Answer:

Outside of probability, Pascal's Triangle is also used for: Algebra, where coefficient of polynomials can be used to find the numbers in Pascal's triangle.  Pascal's Triangle is an arithmetical triangle you can use for some neat things in mathematics.

The entries in Pascal's triangle are actually the number of combinations of N take n where N is the row number starting with N = 0 for the top row and n is the nth number in the row counting from left to right where the n = 0 number is the first number.

The mathematical formula for the number of combinations without repetition is N!/(n!(N-n)!).

Step-by-step explanation:

To construct Pascal's triangle, start with a 1. Then, in the next row, write a 1 and 1. It's good to have spacing between the numbers. In the third row, we have 1 and 1 on the outside slopes. The 2 comes from adding the two numbers above and adjacent. Thus, we are adding the number on the left, 1, with the number on the right, 1, to get 1 + 1 = 2.

In the next row, the 3 comes from adding the 1 and the 2. This particular Pascal's triangle stopped at 1 5 10 10 5 1, but we could have continued indefinitely.

Pulse rates (in beats per minute) were collected on a sample of 36 men. The five number summary for the data is as follows: Lo:
algol13

Answer:

27 men had a pulse rate between 56 & 100.  

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 36

Five number summary:

Lowest value: 56

Lower Quartile: 71

Median: 80

Upper Quartile: 100

Highest value: 140

We have to find the number of men that had a pulse rate between 56 & 100.

56 is the lowest value of data and 100 is the third quartile of data.

Now, the third quartile give 75 percentile of data, thus, 75% of data lies between lowest value and the third quartile.

Thus, 75% of men have a pulse rate between 56 & 100.

Number of men that had a pulse rate between 56 & 100 =

75\% \times n\\\\=\dfrac{75}{100}\times 36 = 27

Thus, 27 men had a pulse rate between 56 & 100.

Use the distributive property to simplify the expression. -6(tsquared+3)-2(tsquared-2)
Mariulka [41]

Answer:Using the distributive property, the problem becomes:

 

5x2 * 3x5 + 5x2 * 2x - 5x2 * 8   and each set of factors may be rearranged as:

 

5 * 3 * x2 * x5 + 5 * 2 * x2 * x - 5x2 * 8    which becomes

 

15x7 + 10x3 - 40x2
