The x- and y-intercepts of the graph of x +6y= 10 is 10 and 5/3.

In the given question we have to find the x- and y-intercepts of the graph of x +6y= 10.

The given equation is x +6y= 10.

To find the x intercept we have to put y=o and to find the y intercept we have to put x=0.

Firstly finding the x intercept by putting y=0 in the equation.

x +6×0= 10

x+0=10

x=10

Now finding the y intercept by putting x=0 in the equation.

0 +6y= 10

6y = 10

Divide by 6 on both side

6/6 y =10/6

y=5/3

Hence, the x- and y-intercepts of the graph of x +6y= 10 is 10 and 5/3.

The Area of the fabric required is 3.6 square feet

The square's side length is 3 feet.

Due to the fact that Lin is creating a window covering for a window that is half circle-shaped on top of a square.

The window covering must therefore be a semicircle with a 3-feet diameter.

thus the semicircle's radius is equal to d/2 = 3/2 feet

Now, the Area of the semicircle,

[tex]A =\frac{1}{2} \pi r^{2} \\[/tex]

Putting the value of the radius in the equation, we have,

[tex]A =\frac{1}{2} \pi (\frac{3}{2} )^{2} \\\\A = \frac{1}{2} *\frac{22}{7} *\frac{3}{2} *\frac{3}{2} \\\\A = \frac{99}{28} = 3.53 = 3.6[/tex]

Probability that the sample mean would differ from the true mean by more than 162 dollars if a sample of 71 persons is randomly selected is 50%

Normal probability distribution:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean  and standard deviation 805 , the zscore of a measure X is given by:

Z = (X - μ)/σ

s = σ/√n

In this problem, we have that:

μ = 21053, n = 71, σ = 805

s = 805/√71 = 95.53

Eiher it differs by 162 or less dollars, or it differs by more than 162 dollars. The sum of the probabilities of these events is decimal 1. So

Probability it differs by 160 or less dollars.

pvalue of Z when X = 21053 + 162 = 21215 subtracted by the pvalue of Z when X = 21053 - 162 = 20891.

X = 21215

Z = (X-μ)/σ

Z = (21215-21053)/95.53

Z = 1.69

has a pvalue of 0.091

X = 21568

Z = (X-μ)/σ

Z = (21215-21053)/95.53

Z = 1.69

has a pvalue of 0.041

0.091 -  0.041 = 0.05098

p + 0.50 = 1

p = 0.50

Thus, Probability that the sample mean would differ from the true mean by more than 162 dollars if a sample of 71 persons is randomly selected is 50%

The slope of the line  passing through the points ( -8,8) and ( 2,8) is 0.

What is slope?

The change in y coordinate relative to the change in x coordinate is referred to as a line's slope in mathematics. The symbols y and x stand for the net change in the y-coordinate and the net change in the x-coordinate, respectively. Therefore, the relationship between the change in the y-coordinate and the change in the x-coordinate is given by m = change in y/change in x = y/x. where'm' denotes a line's slope

Here the given points are,

[tex](x_1,y_1)=(-8,8)\\(x_2,y_2)=(2,8)[/tex]

Now using slope formula ,

As per the given sales tax, the total cost of the bicycle is $1056.194

Sales tax:

Sales tax is defined as the amount of money, calculated as a percentage, that is added to the cost of a product or service when purchased by a consumer at a retail location.

Given,

DeShawn buys a bicycle that costs $129.95. The sales-tax rate in his city is 712%.

Here we need to find the total cost of the bicycle.

Let us consider the 712% is applied as the tax for $129.95.

So, the amount of tax is calculated as,

=> 712% of 129.95

=>  712/100 x 129.95

=> 7.12 x 129.95

=> 926.244

Therefore, the total amount is obtained by adding the tax amount plus the cost of bicycle,

Then,

=>  129.95 + 926.244

=> 1056.194.

Therefore, the total cost of the bicycle is $1056.194.

Hello..!

We use the Pythagorean formula:

[tex] \sf \red{c {}^{2} } = \blue{ a {}^{2} + b {}^{2} }[/tex]

We know that once we have the formula we extract the Raised data:

[tex] \sf \red{c {}^{2}} = \blue{(20cm) {}^{2} + (18cm) {}^{2} }[/tex]

Having the Raised data, we will add as a power and we know that:

[tex] \sf \red{20 {}^{2} } = \orange{400}[/tex]

[tex] \sf \red{18 {}^{2}} = \orange{324}[/tex]

So, to solve a power we must multiply squared and then get our result, in this case I added and then increased it by 0

[tex] \sf \red{c {}^{2} }= \blue{400cm {}^{2} + 324cm {}^{2} }[/tex]

We have the results, once that is done we will add.

[tex] \sf \red{400 + 324 }= \blue{724}[/tex]

So, we have the result we just have to put it like this:

[tex] \sf\red{c {}^{2} } = \blue{724cm {}^{2} }[/tex]

Once we have our result, we must take the square root, then the (square "²") automatically disappears.

In the question ,

it is given that

the when the object is dropped from height h then the velocity with which it hits the ground is given by the formula

v = √(19.6×h)

to find the height it was dropped , and it hits the ground with velocity 25.7 meter per second ,

we substitute v = 25.7 in the equation v = √(19.6×h) ,

we get ,

squaring both the sides , we get

19.6 × h = 25.7²

19.6 × h = 660.49

h = 660.49/19.6

The maximum height reached by the object is 88 feet.

The function is given as

h(t) = -16t² + 72t + 7

Differentiate the above function

So, we have the following representation

h'(t) = -32t + 72

Set to 0

-32t + 72 = 0

So, we have

32t = 72

Divide by 32

t = 2.25

Hence, the time is 2.25 seconds

In (a), we have

t = 2.25

Substitute t = 2.25 in h(t) = -16t² + 72t + 7

The corresponding angle postulate states that the corresponding angles are congruent if the transversal intersects two parallel lines. In other words, if a transversal intersects two parallel lines, the corresponding angles will be always equal.

Alternate angle theorem states that when two parallel lines are cut by a transversal, then the resulting alternate interior angles or alternate exterior angles are congruent.

The average rate of change of the function g(x) = x² – 1 from x = 3 to x = 6 is 9.

What is the average rate of change of a function?

The average rate of change function describes the average rate at which one quantity changes in proportion to another's change.

We can write the Average Rate of Change of a function f from a to b as follows using function notation:

                                   [tex]r = \frac{g(b)-g(a)}{b-a}[/tex]

The given function is g(x) = x² – 1.

Then the rate of change of a function from x = 3 to x = 6.

so the value of a =  3 and b = 6, using the above formula, we get

                                           [tex]r = \frac{g(b)-g(a)}{b-a}\\r = \frac{g(6)-g(3)}{6-3}\\r = \frac{(36-1)-(9-1)}{6-3}\\\\r = \frac{35-8}{3}\\r = \frac{27}{3}\\\\r = 9[/tex]

A circle graph is attached.

A circle graph, also known as a pie chart, is used to visualize information and data. A circle graph is commonly used to show the results of an investigation in a proportional manner. The arcs of a circle graph are proportional to the percentage of the population who answered a specific question.

Given data

Top-selling US kids magazine as of 2002

Seventeen      2.352

Ym                      2.242

Teen              1.729

Teen people      1.625

Boys              1.280

First, we have to add up the dataset

Total = 2.352 + 2.242 + 1.729 + 1.625 + 1.280

= 9.228

The proportion of each magazine is then calculated.

This is calculated by dividing each magazine's frequency by the total frequency.

Mathematically, the formula is represented as:

Proportion = issue sold/ Total magazines sold

So we have

Seventeen= 2.352/9.228

= 25.5%

Seventeen= 2.242/9.228

= 24.3%

Seventeen= 1.729/9.228

Answer:

Table B

Step-by-step explanation:

To determine whether or not something is linear, we find the slope between two different coordinates and see if that slope remains consistent throughout the data. To find the slope between two points, use the equation (y2-y1)/(x2-x1)

Table A -->  (-1-5)/(3-2) = -6/1 = -6

Now we have to see if the slope remains consistent in "Table A" by finding the slope using two other coordinates:

(6-3)/(5-4) = 3/1 = 3

We see that the slope is not consistent in Table A, so we repeat the same steps with the other Tables to find one with a consistent slope.

Table B --> (0- -3)/(5-3) = 3/2

                  (6-3)/(9-7) = 3/2

Table B's data creates a consistent slope, so Table B represents a linear function.
