Answer:
The domain (input values) of the sine function is:
O B. all real numbers
The domain of the sine function will be all real number. Then the correct option is B.
What are domain and range?The domain means all the possible values of x and the range means all the possible values of y.
Simply put, trigonometric functions also referred to as cyclic capabilities the functions of a triangle's inclination.
Let the sine function be f(x) = sin x.
It is a function that repeats itself in a particular time interval.
The domain of the sine function will be all real number.
And the range of the sine function will be [1, –1].
Then the correct option is B.
The graph of the sine function is given below.

use the matrix tool to solve the system of equations enter the answer as an ordered pair. 8x+5y=9 -x+y=7
Answer:
x = -44/13
y = -65/13
Step-by-step explanation:
Using matrix form means using the crammers rule
The matrix form of the expression is written as;
[tex]\left[\begin{array}{ccc}8&5\\-1&1\\\end{array}\right] \left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{ccc}9\\7\\\end{array}\right][/tex]
AX = B
taking the determinant of A;
|A| = 8(1) - 5(-1)
|A| = 8 + 5
|A| = 13
After replacing the first row with the column matrix;
[tex]A_x =\left[\begin{array}{ccc}9&5\\7&-1\\\end{array}\right][/tex]
|Ax| = 9(-1)-5(7)
||Ax| = -9 - 35
|Ax| = -44
x = |Ax|/|A|
x = -44/13
similarly for y
[tex]A_x =\left[\begin{array}{ccc}8&9\\-1&7\\\end{array}\right][/tex]
|Ay| = 8(7)+9
|Ay| = 56+9
|Ay| = 65
y = |Ay|/|A|
y = -65/13

You flip a coin 50 times and get 26 tails. What is the experimental probability of flipping heads? Write your answer as a simplified fraction or a percentage.
Answer:
12/25
Step-by-step explanation:
If you got 26 tails, that means you got 50 - 26 or 24 heads. The experimental probability can be represented by the desirable flips over the total number of flips. We are looking for heads, so the amount of heads is the amount of desirable flips, and the total is 50. From this, we get the fraction 24/50 which simplifies to 12/25.
Since there are no restrictions on the strings, we can think of this problem as drawing 5 random digits in sequence. There is a 9/10 chance each time we draw to NOT get a 4. Every time we draw, we multiply by 9/10 again until we've draw 5 digits. Thus, the answer is (9/10)^5 :)
Answer:
[tex]Pr = 0.59049[/tex]
Step-by-step explanation:
See Comment for Complete Question
Given that A has 5 digits. A digit in A can be chosen from 0 to 9 (10 digits).
However, selection without 4 means that we can only select from 0 to 3 and 5 to 9 (altogether, that is 9 digits)
The probability of selecting a number other than 4 in each of the digit is:
[tex]1st \to \frac{9}{10}[/tex]
[tex]2nd \to \frac{9}{10}[/tex]
[tex]3rd \to \frac{9}{10}[/tex]
[tex]4th \to \frac{9}{10}[/tex]
[tex]5th \to \frac{9}{10}[/tex]
So, the required probability is:
[tex]Pr = 1st * 2nd * 3rd * 4th * 5th[/tex]
[tex]Pr = \frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10}[/tex]
[tex]Pr = \frac{9^5}{10^5}[/tex]
[tex]Pr = \frac{59049}{100000}[/tex]
[tex]Pr = 0.59049[/tex]

1a.) Brian borrowed 4 non-fiction books from the library. This was 25% of the
books he checked out. How many books did Brian check out? *
Answer:
Total number of books borrowed= 16
Step-by-step explanation:
Giving the following information:
Number of non-fictions books= 4
Percentage of books borrowed= 25% = 0.25
To calculate the total number of books borrowed, we need to use the following formula:
Total number of books borrowed= 4 / 0.25
Total number of books borrowed= 16

Select the correct answer. What is the approximate distance between points D and E? Round your answer to the nearest hundredth. A.
Answer:
The approximate distance between points D and E is 8.25
Step-by-step explanation:
The figure is as follows :
To find - What is the approximate distance between points D and E ?
Solution -
By Pythagoras Theorem, we get
(DE)² = (FE)² + (DF)²
= (8)² + (2)²
= 64 + 4
= 68
⇒(DE)² = 68
⇒DE = √68
⇒DE = 8.246
∴ we get
The approximate distance between points D and E is 8.25

y =2 / (5x - 4)(4x - 9)
Answer:
x ≠ 4/5, x ≠ 9/4
You can also write it as "all real numbers except 4/5 and 9/4."
Step-by-step explanation:
The denominator of a fraction cannot equal 0. We can write this relation to find what x does NOT equal:
(5x - 4)(4x - 9) ≠ 0
We can use the zero-product property to get two separate equations:
5x - 4 ≠ 0
5x ≠ 4
x ≠ 4/5
4x - 9 ≠ 0
4x ≠ 9
x ≠ 9/4
A company is testing a new protein shake which they claim works better than their existing brand in improving an athlete's performance. The company selected 60 athletes from a training camp database, and divided them into three groups. The ages for the groups were 16 to 20 years, 21 to 25 years, and 26 to 30 years. In each group, half of the subjects were asked to use the new protein shake for a month, and the other half were asked to use the company's existing brand for a month. The subjects were not informed about which protein shake they would be using. Which statements about this study are true? The study uses blocking to reduce variability from known factors. The study does not use a control group. The study uses random sampling. The study uses blocking on the basis of gender.
