Which are the vertically opposite angles?

Which are the supplementary angles?

Which are the adjacent angles?

Answer:

There are 9 dimes and 18 nickels.

Step-by-step explanation:

Let d = be the number of dimes

     n = be the number of nickels

    d + n = 27...eq.1

   0.10d + 0.05n = 1.80...eq.2

Solve the system of equations

   d + n = 27

10d + 5n = 180  ( multiply eq.2 by 100 )

 -5d - 5n = -135

      5d = 45

        d = 9 , there are 9 dimes so,0.90

        n = 27 - 9 = 18,   there are 18 nickels so, 0.90

To check:   9 dimes + 18 nickels = 27 coins

                0.90 + 0.90 = $ 1.80 total value of the coins

Answer:

alpha=0.01

Step-by-step explanation:

confidence level = 1 - alpha

so alpha = 1 - confidence level = 1 - 0.99 = 0.01

In statistics, alpha represents the value that checks the test statistic in order to determine if it is significant or not. In other words, alpha is the acceptable margin of type 1 error. Alpha is also called the significance level, which opposes the confidence level. Significance level + confidence level = 1.

Answer:

68

Step-by-step explanation:

To get the sample size of the population, we will use the formula for calculating the standard error of the mean. This is expressed as;

SE = zσ/√n

z is the z score at 90% confidence

σ is the standard deviation

n is the sample size

SE is the mean weight loss

Given

z = 1.645

σ = 10

SE = 2

Required

sample size n

Substitute into the given equation;

SE = zσ/√n

2 = (1.645)(10)/√n

2 = 16.45/√n

√n = 16.45/2

√n = 8.225

n = (8.225)²

n = 67.650625

Hence the total sample should be about 68

The answer is

[tex] \huge y = 2x + 15[/tex]

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

From the question we have

[tex]y - 3 = 2(x + 6) \\ y - 3 = 2x + 12 \\ y = 2x + 12 + 3[/tex]

We have the final answer as

[tex]y = 2x + 15[/tex]

Answer:

y = 7x - 47

Step-by-step explanation:

y = mx + b (m is slope, b y-intercept)

Parallel lines have the same slope.

y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )

~~~~~~~~~~~~~~~~

y = 7x + 1

m = 7

(6, - 5)

y + 5 = 7 (x - 6)

y = 7x - 47

Answer:

x and y intercepts are alike because they're both on the graph ,they help you graph a line, they can be both found in the slope-intercept form equation

they're different one is when it can be found where it crosses the X line and one can be found where it's the y line, when is found at the end of the equation for slope intercept form and what is found near the slope. x-intercept is an input and y-intercept is an output

No

Step-by-step explanation:

a function can not repeat

The table given in the problem does not represent a function.

A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.

The ordered pair for data given in the table is as below,

{(2, 5), (3, 6), (4, 6), (5, 9), (8, 11)}

Suppose x denotes the first elements and y the second elements of the  ordered pair.

Then, from the ordered pair it is concluded that for x = 3 and x = 4, the value of y is 6.

Which implies that the values of x are not unique for a given value of y.

Thus, it does not represent a function.

Hence, the given table does not represent a function as the values in the domain set are not unique.

Answer:

( t + 6 ) ( t − 6 )

Step-by-step explanation:

t 2 − 36

since 36 is a square number, you'll have to unsquare it to get

t 2 −  [tex]6^{2}[/tex]

Since both terms are perfect squares, factor using the difference of squares formula,  a 2 − b 2 = ( a + b )( a − b )  where  a = t  and  b = 6

You should get :  ( t + 6 ) ( t − 6 ) !

Answer:

x-8 is a factor of f(x)

Step-by-step explanation:

The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).

We are given the function

[tex]f(x)=-2x^3+17x^2-64[/tex]

And it's required to find if x-8 is a factor of f.

Applying the mentioned theorem, we only have to find f(8):

[tex]f(8)=-2\cdot 8^3+17\cdot 8^2-64[/tex]

Operating:

[tex]f(8)=-2\cdot 512+17\cdot 64-64[/tex]

[tex]f(8)=-1024+1088-64[/tex]

[tex]f(8)=0[/tex]

Thus, x-8 is a factor of f(x)

Answer:

(a). y = 3x - 11 ; (b). y = [tex]-\frac{1}{3}[/tex] x - 1

Step-by-step explanation:

Parallel lines have the same slopes

Slopes of perpendicular lines are opposite reciprocals.

(3, - 2)

The slope of given line is 3

(a). Equation of ║ line is

y + 2 = 3(x - 3)

y = 3x - 11

(b). Slope of perpendicular line is [tex]-\frac{1}{3}[/tex]

y + 2 = [tex]-\frac{1}{3}[/tex] (x - 3)

y = [tex]-\frac{1}{3}[/tex] x - 1

The required equation of a line parallel to the line will be y = 3x - 7

The required equation of the perpendicular line is y = -1/3 - 7

Using the coordinate points to get the equation of the line (1, -4) and (2, -1)

The standard form of the equation is expressed as y = mx + b

m is the slope

b is the y-intercept

Get the slope:

m = y2-y1/x2-x1

m = -1+4/2-1

m = 3/1

m = 3

Get the y-intercept

-4 = 3(1) + b

b = -4-3

b = -7

The required equation of a line parallel to the line will be y = 3x - 7

For the equation of the line perpendicular, the slope of the line will be -1/3

The required equation of the perpendicular line is y = -1/3 - 7
