Answers

Answer:

Length = 13 in

Width = 10 in

Step-by-step explanation:

Let L be the length.

Let W be te width.

From the question given above, the Lenght is 3 more that the width i.e

L = 3 + W

Next, we shall determine the width (W). This can be obtained as follow:

Length (L) = 3 + W

Width (W) = W

Area (A) = 130 in²

A = L × W

130 = (3 + W) × W

Clear bracket

130 = 3W + W²

Rearrange

W² + 3W – 130 = 0

Solving by formula method

W = –b ± √(b² – 4ac) / 2a

a = 1

b = 3

c = –130

W = –3 ± √(3² – 4 × 1 × –130) / 2 × 1

W = –3 ± √(9 + 520) / 2

W = –3 ± √(529) / 2

W = –3 ± 23 / 2

W = –3 + 23 / 2 or –3 – 23 / 2

W = 20/2 or –26/2

W = 10 or –13

Since measurement can not be negative, the width is 10 in.

Finally, we shall determine the length. This can be obtained as follow:

L = 3 + W

W = 10

L = 3 + 10

L = 13 in

SUMMARY

Length = 13 in

Width = 10 in

Jack and his friends are going hiking next week. There are four trails they can hike: Grayson Pass, Giant’s Ridge, Three Summits, and Elderberry. To make a decision, they use a spinner divided into four colors. They spin it 60 times to check the fairness of their model and record the results in this table.
The relative frequency of the spinner landing on green is


The relative frequency of the spinner landing on blue is


The relative frequency of the spinner landing on yellow is


The relative frequency of the spinner landing on red is

Answers

Answer:

Step-by-step explanation:

The theoretical frequency would be 1/4, and if spun 60 times, 15/60.

The relative frequency is how many times it actually landed on each color.

So green is 6/60

Blue is 24/60

Yellow is 9/60

Red is 21/60

I don't know if they want these in their simplest form (sometimes the test says one way or the other), but here they are, reduced:

Green: 1/10

Blue: 4/10

Yellow: 3/20

Red: 7/20

Please let me know if you have questions, or if it's marking these answers wrong.

Find the area of this trapezoid. Be sure to include the correct unit in your answer.

Answers

Answer:

A = 55 in²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₁ the parallel bases

Here h = 5, b₁ = 5 and b₂ = 17 , then

A = [tex]\frac{1}{2}[/tex] × 5 × (5 + 17) = 2.5 × 22 = 55 in²

Answer: 55

Step-by-step explanation: A=a+b

Here we consider a similar problem, called maximum-sum common subsequence problem, as follows. Let A be an array of n numbers and B another array of m numbers (they may also be considered as two sequences of numbers). A maximum-sum common subsequence of A and B is a common subsequence of the two arrays that has the maximum sum among all common subsequences of the two arrays (see the example given below). As in the longest common subsequence problem studied in class, a subsequence of elements of A (or B) is not necessarily consecutive but follows the same order as in the array. Note that some numbers in the arrays may be negative. Design an O(nm) time dynamic programming algorithm to find the maximum-sum common subsequence of A and B. For simplicity, you only need to return the sum of the elements in the maximum-sum common subsequence and do not need to report the actual subsequence. Here is an example. Suppose A {36, 12, 40, 2, -5,7,3} and B : {2, 7, 36, 5, 2, 4, 3, -5,3}. Then, the maximum-sum common subsequence is {36, 2, 3). Again, your algorithm only needs to return their sum, which is 36 +2+3 = 41. Please help me with this question. Every help is appreciated.
