Answer:

∠ FAB = 75°

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ FAB is an external angle, thus

13x - 3 = 3x + 2 + 55 = 3x + 57 ( subtract 3x from both sides )

10x - 3 = 57 ( add 3 to both sides )

10x = 60 ( divide both sides by 10 )

x = 6

Thus

∠ FAB = 13x - 3 = 13(6) - 3 = 78 - 3 = 75°

Answer:

x = -3, and y = -3, or the ordered pair is (-3, -3)

Step-by-step explanation

To solve this system, you can use the elimination method:

First, write both equations down.

12x - 8y = -12

6x + 4y = -30

If you multiply the second equation by 2, you can eliminate x. Rewrite the first equation, and multiply the second one by 2:

12x - 8y = -12

12x + 8y = -60

Once added, you get the equation:

24x = -72

x = -3

Now, we just plug -3 into one of the equations and solve for y:

12x - 8y = -12

12(-3) - 8y = -12

-36 - 8y = -12

-8y = 24

y = -3

So, x=-3, and y=-3, or the ordered pair is (-3, -3)

Answer:

True

Step-by-step explanation:

In Functions and Function Notation, we were introduced to the concepts of domain and range. In this section, we will practice determining domains and ranges for specific functions. Keep in mind that, in determining domains and ranges, we need to consider what is physically possible or meaningful in real-world examples, such as tickets sales and year in the horror movie example above. We also need to consider what is mathematically permitted. For example, we cannot include any input value that leads us to take an even root of a negative number if the domain and range consist of real numbers. Or in a function expressed as a formula, we cannot include any input value in the domain that would lead us to divide by 0.

Diagram of how a function relates two relations.

Figure 2

We can visualize the domain as a “holding area” that contains “raw materials” for a “function machine” and the range as another “holding area” for the machine’s products.

We can write the domain and range in interval notation, which uses values within brackets to describe a set of numbers. In interval notation, we use a square bracket [ when the set includes the endpoint and a parenthesis ( to indicate that the endpoint is either not included or the interval is unbounded. For example, if a person has $100 to spend, he or she would need to express the interval that is more than 0 and less than or equal to 100 and write

(

0

,

1

0

0

]

(0, 100]. We will discuss interval notation in greater detail later.

Let’s turn our attention to finding the domain of a function whose equation is provided. Oftentimes, finding the domain of such functions involves remembering three different forms. First, if the function has no denominator or an even root, consider whether the domain could be all real numbers. Second, if there is a denominator in the function’s equation, exclude values in the domain that force the denominator to be zero. Third, if there is an even root, consider excluding values that would make the radicand negative.

Before we begin, let us review the conventions of interval notation:

The smallest term from the interval is written first.

The largest term in the interval is written second, following a comma.

Parentheses, ( or ), are used to signify that an endpoint is not included, called exclusive.

Brackets, [ or ], are used to indicate that an endpoint is included, called inclusive.

The table below gives a summary of interval notation.

Summary of interval notation. Row 1, Inequality: x is greater than a. Interval notation: open parenthesis, a, infinity, close parenthesis. Row 2, Inequality: x is less than a. Interval notation: open parenthesis, negative infinity, a, close parenthesis. Row 3, Inequality x is greater than or equal to a. Interval notation: open bracket, a, infinity, close parenthesis. Row 4, Inequality: x less than or equal to a. Interval notation: open parenthesis, negative infinity, a, close bracket. Row 5, Inequality: a is less than x is less than b. Interval notation: open parenthesis, a, b, close parenthesis. Row 6, Inequality: a is less than or equal to x is less than b. Interval notation: Open bracket, a, b, close parenthesis. Row 7, Inequality: a is less than x is less than or equal to b. Interval notation: Open parenthesis, a, b, close bracket. Row 8, Inequality: a, less than or equal to x is less than or equal to b. Interval notation: open bracket, a, b, close bracket.

Answer:

Step-by-step explanation:

Because Bryce did 7/8 hours every day for 20 days,

7/8 hours is 52.5 minutes.

so then times 20, you will get 1050 minutes.

Then divided by 60(minutes per hour) you will get 17.5 hours,

which means she did 17 hours and 30 minutes in the first 20 days,

then you plus the last 1 hour per day for 10 days,

you will get 10 hours plus 17 hours and 30 minutes.

So Bryce have worked 27 and 30 minutes in september.

1.92559524e+14

Step-by-step explanation:

6.47 x 10^-15 and 3.36 x 10^-29 are written in scientific notation. In this way, we have a quotient of two numbers written in scientific notation. To solve this problem, we have:

6.47/3.36 x 10^{[-15-(-29)]}=1.92559524 x 10^{(-15+29)}

Therefore 1.92559524 x 10^{14}  or 1.92559524e+14

1.92559254e+ 14 is the correct value of the given expression.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

given a number  6.47x10^-15/3.36x10^-29

Solving this given number using PEMDAS

=> 6.47x10^-15/3.36x10^-29

=> (6.47 * 10⁻¹⁵) / (3.36 * 10⁻²⁹)

=> (6.47 / 3.36) * 10⁻¹⁵ ⁺ ²⁹

=> 1.92559254 * 10¹⁴

in Scientific notation:

=> 1.92559254e+ 14

therefore, the correct value of the given expression is 1.92559254e+ 14.

Step-by-step explanation:

(3²-2³)⁶⁶ = (9 - 8)⁶⁶ = (1)⁶⁶ = 1

(3²-2³)⁶⁶ total​ is 1

To evaluate (3²-2³)⁶⁶, we will first simplify the expression we have in the bracket before carrying out the power operation

From (3²-2³)⁶⁶

(3²-2³) can be simplified as shown below

3² = 3 × 3 = 9

and

2³ = 2 × 2 × 2 = 8

∴ (3²-2³) = (9 - 8) = (1)

∴ (3²-2³)⁶⁶ becomes (1)⁶⁶

(1)⁶⁶ = 1

(NOTE: 1 raised to any power is 1)

Hence, (3²-2³)⁶⁶ total​ is 1

Answer:

42 Comedy, 49 Action, 21 Horror

Step-by-step explanation:

6 comedy : 7 action : 3 horror = 16 parts or if you think of it as a fraction, 16 is the denominator and the numbers for each ratios are the numerators

112 (the total)/16 = 7 movies per part

6 parts of comedy = 6 x 7 = 42

7 parts action = 7 x 7 =49

3 parts horror = 3 x 7 = 21

Another way to think of it is:

(ex. comedy)

6/16=x/112

Answer:

The critical values of r are -0.708 and 0.708.

Step-by-step explanation:

A statistical test is being performed to determine whether there is any linear correlation between two variables.

The hypothesis can be defined as follows:

H₀: There is no  linear correlation between two variables, i.e. ρ = 0.

Hₐ: There is a significant linear correlation between two variables, i.e. ρ ≠ 0.

The test statistic is given as follows:

[tex]t = \frac{r\sqrt{n-2}}{\sqrt{1-r^{2}}}[/tex]

The degrees of freedom of the test is:

[tex]\text{df}=n-2=12-2=10[/tex]

The significance level of the test is, α = 0.01.

The critical values of r are:

[tex]r_{\alpha/2, (n-2)}=r_{0.01/2, (12-2)}=r_{0.005, 10}=\pm0.708[/tex]

*Use the r critical value table.

Thus, the critical values of r are -0.708 and 0.708.

From the 'r' table, the values of 'r' are -0.708 and 0.708.and this can be determined by using the hypothesis test.

Given :

The hypothesis test is performed in this problem. The null and alternate hypothesis is:

[tex]\rm H_0 : p=0\\[/tex]

[tex]\rm H_1:p\neq 0[/tex]

The t-statistics is given by:

[tex]\rm t =\dfrac{r\sqrt{n-2} }{\sqrt{1-r^2} }[/tex]

Degree of freedom is given by:

df = n - 2 = 12 - 2 = 10

The significance level for this test is [tex]\alpha = 0.01[/tex]

Now, the critical value r is given by:

[tex]\rm r_{\alpha /2,(n-2)}=r_{0.01/2,(12-2)}=r_{0.005,10} = \pm0.708[/tex]

So, from the 'r' table, the values of 'r' are -0.708 and 0.708.
