Answer:

78-x=61, subtract by 61 on both sides to get 17-x=0, so x would have to be 17

Answer:

(x-8)^2 + (y-4)^2 = 16

Step-by-step explanation:

Standard equation of a circle is expressed as;

(x-a)^2 + (y-b)^2 = r^2

(a, b) is the centre

r is the radius

Given

Centre (8, 4)

r =  4

Substitute

(x-8)^2 + (y-4)^2 = 4^2

(x-8)^2 + (y-4)^2 = 16

This gives the required equation

Answer:

(x-8)^2 + (y-4)^2 = 16

Answer:

He can choose 4 good hitters and 1 poor hitter in 630 different ways.

Step-by-step explanation:

The order in which the hitters are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In how many ways can he choose 4 good hitters and 1 poor hitter?

4 good hitters from a set of 8.

1 poor hitter from a set of 9. So

[tex]T = C_{8,4}*C_{9,1} = \frac{8!}{4!(8-4)!}*9 = 630[/tex]

He can choose 4 good hitters and 1 poor hitter in 630 different ways.

Answer:

a right triangle

Step-by-step explanation:

as long a a triangle has one angle of 90 degrees, then it is a right triangle. An acute triangle has to have an angle less than 90 degrees, and an obtuse angle has to have an angle greater than 90 degrees.

Answer:

Area of pupil = 0.007855 square inch.

Step-by-step explanation:

Given the following data;

Diameter = 0.1 inch

To find the area of the pupil (circle);

Area of circle = π(D/2)²

Area of pupil = 3.142*(0.1/2)²

Area of pupil = 3.142*(0.05)²

Area of pupil = 3.142*0.0025

Area of pupil = 0.007855 square inch.

Answer:

[tex]y=7x -7[/tex]

Step-by-step explanation:

We are given two points, the y - intercept and the x - intercept.

The y - intercept being: ( 0, -7 )

The x - intercept being: ( 1, 0 )

The equation of a line in slope - intercept form is:

y = mx + b, where m is the slope and b is the y - intercept.

We already have the y - intercept. So far we have:

y = mx - 7

What we're missing is the slope.

To find the slope, we can use this formula:

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex], where [tex]x_{2}[/tex] and [tex]x_{1}[/tex] are the x - coordinates of both points and [tex]y_{2}[/tex] and [tex]x_{1}[/tex] are the y - coordinates of both points.

[tex]m=\frac{0-(-7)}{1-0} \\\\m=\frac{7}{1}\\m=7[/tex]

We now have the missing piece, the slope, so the equation now is:

[tex]y=7x -7[/tex]

Step-by-step explanation:

perimeter is (pi×diameter)/2

Problem 1

Answer: No, it is not a statistical question

Explanation:

This is because the question is directed at a specific family, your family in particular. If the surveyor is only asking one person, then there's no need for statistics since a sample isn't formed.

If the question is posed to many people taking a survey, then it would be statistical in nature. However, no further context or clarification is given, so I'll assume that the question is directed at one person, or one family, only. I think your teacher would say "During which month do families take vacation?" to be more general and involve statistics.

==============================================================

Problem 2

Answer: The statistical variable is the number of tv sets owned, and this variable is quantitative

Explanation:

The variable is what we want to figure out, and it's random in nature. Hence the name "random variable". It takes on nonnegative whole numbers 0,1,2,3,... so we can see the data set is discrete. The term "discrete" in math means that there aren't infinitely many numbers between two values. For example, if we pick 2 and 5, we can see the values 3,4 are between them and that's it. Contrast this with a continuous data set and there are infinitely many real numbers between 2 and 5 (eg: 2.78912 and 3.412)

While it might be tempting to think of a discrete number set as finite, that's not entirely true. We have infinitely many nonnegative whole numbers to work with. Though of course, there's a realistic limit that we arrive to and someone having 277 televisions is completely out of the ordinary, if not impossible.

The data variable "Number of TV sets owned" is not only discrete, but it's also ordinal, interval and ratio data as well. Here's a breakdown of what I mean

Since we have many terms apply to this, it sometimes helps to pick just one and try to have it describe the others implicitly. So we go for ratio data since that encapsulates interval and ordinal data types as well. If something is ratio, then automatically it must be ordinal and interval. Division depends on the numbers being well ordered, and that gaps between values make sense and are consistent.

To recap, the data type is quantitative, discrete, and we have a ratio scale.

The variable "number of tv sets owned" is not categorical since the choices to pick from 0,1,2,3,... aren't names; instead they are numbers in which we can perform math operations on and have it make sense. So that's why we go for quantitative data instead of categorical. If it asked "what brand of TV are owned by families?", then the categories of the various brand names would be the answer choices, and lead to categorical data.

Side note: categorical data is always qualitative

Answer:

$158 per payment

Step-by-step explanation:

$1896 divided by 12

=158

(5x + 2) + (4x + 5)

= 5x + 2 + 4x + 5

= 5x + 4x + 5 + 2

= 9x + 7

Answer:

0.8x or 0.2x

Step-by-step explanation:

20% of x = 20/100 × x = 0.2x

So discount price = x - 0.2x = 0.8x

Answer (assuming it can be in slope-intercept form):

[tex]y = -\frac{6}{5} x+3[/tex]  

Step-by-step explanation:

1) First, use the slope formula [tex]m =\frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope of the line. Substitute the x and y values of the given points into the formula and solve:

[tex]m =\frac{(-3)-(3)}{(5)-(0)} \\m = \frac{-3-3}{5-0}\\m = \frac{-6}{5}[/tex]

So, the slope is [tex]-\frac{6}{5}[/tex].  

2) Now, use the slope-intercept formula [tex]y = mx + b[/tex] to write the equation of the line in slope-intercept form. All you need to do is substitute real values for the [tex]m[/tex] and [tex]b[/tex] in the formula.

Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{6}{5}[/tex] for it. Since [tex]b[/tex] represents the y-intercept, substitute 3 for it. (Remember, the y-intercept is the point at which the line hits the y-axis. All points on the y-axis have an x-value of 0. Notice how the given point (0,3) has an x-value, too, so it must be the line's y-intercept.) This gives the following equation and answer:

[tex]y = -\frac{6}{5} x+3[/tex]

Answer:

C. 66 square units

Step-by-step explanation:

The area of the middle rectangle would by base × height, or y × h, or 6 × 6.

The area is 36.

The area for one triangle would 1/2 × base × height.

(But since there are two triangles to solve for, the 1/2 is not necessary, and we can just do base × height again.)

So, it would be x × h, or 5 × 6.

The area is 30.

Combine both areas to get the whole area of 66 units²
