The equation for the line of best fit can be obtained as follows, using the least square method (for more info visit http://hotmath.com/hotmath_help/topics/line-of-best-fit.html ):

mean of X = 1/6
mean of Y = 2/3

slope, m = 704/1121 = 0.6

Computing the y-intercept using the formula:

b = mean of Y - m (mean of X) = 2/3 - (704/1121)(1/6)
b = 0.562 = 0.6

Therefore, the equation of the line of best fit, given the standard relation:

y = mx + b

y = 0.6x + 0.6

Julia is a measuring a table for her room. The area of the tables 46 7/8 square feet. The length of the table is 7 1/2 feet. Jul
Irina18 [472]
In this question, you have given the table length (7. 1/2 feet) and the table maximal area (46 7/8 square feet).  The question is about whether Julia buys a table greater than 6ft wide, in other words, we need to determine the table maximum width. The equation from this problem can be written as:
Table max area = 46 7/8 ft
Table length= 7 1/2 ft

Using area formula, the calculation for maximal width would be:
length * max width = max area
7 1/2 ft * max width = 46 7/8 ft
max width = 46.875/ 7.5 = 6.25ft

The answer to this question would be yes, she can buy a table with more than 6 ft width. But it should not more than 6.25ft width

The ratio of the perimeter of square RSTU to the perimeter of square WXYZ is 1 to 3. The area of square RSTU is 36 square inches
Ainat [17]
√36 square inches = 6 inches (length of sq RSTU)
6 inches x 4=24 inches (per. of sq RSTU)
-----------------------------------
1u=24 inches
3u=24 inches x 3=72 inches (per. of sq WXYZ)
-----------------------------------
72 inches ÷ 4=18 inches (length of sq WXYZ)
18 inches x 18 inches = 324 square inches( area of sq WXYZ)

Ans: 324 square inches

On saturday, you bowl at mar vista bowl, where renting shoes costs $2 and each game bowled is $3.50. on sunday, you bowl at pinz
ExtremeBDS [4]

Given, at Mar Vista bowl the cost of renting shoes = $2.

The cost for each game bowled = $3.50

There are g games given. So the cost for g games bowled = $(3.50)(g) = $(3.50g)

The total amount soent at Mar Vista Bowl = $(2+3.50g)

At Pinz, the cost for shoe rental = $5.

The cost for each game bowled = $3.25.

So the cost for g game bowled = $(3.25)(g) = $(3.25g)

Total amount spent at Pinz = $(5+3.25g)

Given, the amount spent ateach of the places is same.

so we can write the equation as,

2+3.50g = 5+3.25g

We will move 3.25 to the left side by subtracting it from both sides. we will get,

2+3.50g-3.25g = 5+3.25g-3.25g

2+0.25g = 5

Now we will move 2 to the right side by subtracting 2 from both sides. We will get,

2+0.25g-2 = 5-2

0.25g = 3

Now to get g we will divide 0.25 to both sides. We will get,

\frac{0.25g}{0.25}= \frac{3}{0.25}

g =\frac{3}{0.25}

g = 12

So we have got the required answer.

The number of games bowled = 12.

Sketch one cycle of the cosine function y= cos 2θ
Liula [17]
Based on function transformations, the graph of y= cos(2θ), is the same as the graph of <span>y= cos(θ), with a component B of 2, in which case, it means the period is the only thing that differs

well the period for this function will then be  </span>\bf \cfrac{2\pi }{B}\iff \cfrac{2\pi }{2}\implies \pi

so, the graph of is, the same as y= cos(θ), just shrunk by half horizontally
