What is the trigonometric ratio?
Trigonometric ratios are the ratios of a right triangle's sides. The sine (sin), cosine (cos), and tangent (tan) are three often used trigonometric ratios. There are other trigonometric ratios which are reciprocals of these ratios.
Trigonometric ratios can be computed either using the provided acute angle or by calculating the ratios of the right-angled triangle's sides.
In the figure,
Adjacent=CB=16
hypotenuse=AC=34

a fair coin is tossed five times, and each time the coin lands tails up. if the coin is then tossed 1990 more times, how many tails are most likely to appear for the 1990 additional tosses?
Answers
Probability of getting tails are most likely to appear for the 1990 additional tosses will be 1/32.
What is probability?Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

Answers
The probability there is at least one pair is therefore 1−p.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.The likelihood that an event will occur increases with its probability.A straightforward illustration is tossing a fair (impartial) coin.The chance of both outcomes ("heads" and "tails") is equal because the coin is fair, "heads" is more likely than "tails," there are no other conceivable outcomes, and the likelihood of either outcome is half.acc to our question-
It is little known, but socks have individual identities. There are (166) equally likely ways to choose 6 socks from the 16.Now we find the number of ways to choose 6 socks, so that there is no pair among them. There are (86) ways to choose the "types" of sock we will have. For each choice of 6 types, there are 26 ways to choose the actual socks. For at each chosen "type" of sock, we have 2 choices as to which of the two socks of that type to take.hence,The probability there is at least one pair is therefore 1−p.

Cheddar Cheese: $3/lb
Swiss Cheese: $5/lb
Answers
Answer:
Only cheddar 10 pounds
Only swiss 6 pounds
Use the equation to find out different combinations.
3x + 5y = 30
For example, 1 pound of cheddar and 5.4 pounds of swiss.
Step-by-step explanation:
Let x = cheddar
Let y = swiss
3x + 5y = 30
If we only wanted cheddar let y be 0
3x =30 Divide both sides by 3
x = 10
You can buy 10 pounds of cheddar.
If we only wanted swiss let x be 0
5y = 30 Divide both sides by 5
y = 6
You can buy 6 pounds of swiss.
1 pound of cheddar:
3(1) + 5y = 30 Subtract 3 from both sides
5y = 27 Divide both sides by 5
y = 5.4

How to find the trigonometric ratio of the angle?Trigonometry is a branch of mathematics dealing with the relationship between the ratios of the sides of a right-angled triangle with its angles.
Given that: sec(θ) = 8 and tan(θ) < 0. This implies:
cos (θ) = 1/8 and tan(θ) is negative. This means θ is quadrant 4
(Note: cos (θ) = 1/sec(θ) )
Using the given information, we can sketch the location of the angle θ in the quadrant (See the attached image).
Thus, we can calculate the value of side d using the Pythagoras theorem
d = √(8² - 1²) = √63 = 3√7
The side is -d = -3√7
Note: the side d is negative in the quadrant
Therefore:
cos(θ) = 1/sec(θ) = 1/8
sin(θ) = (-3√7)/8
tan(θ) = (-3√7)/1 = -3√7
csc(θ) = 8/(-3√7) = - (8√7)/21

slope = 2/5
; passes through (–3, 1)
Answers
Answer:
The equation of the line in slope-intercept form is [tex]y=0.4x+2.2[/tex]
Step-by-step explanation:
The equation of the line in slope-intercept form can be calculated as follows ?
The first step is to find the slope-intercept form of the given line by the point-slope form formula as follows
[tex]y-y_{1}=m(x-x_{1})[/tex]
Where [tex]m[/tex] is the slope of the line
Write the given value of the slope
[tex]m=\frac{2}{5}[/tex]
Convert the value of the slope into decimal
[tex]m=0.4[/tex]
The second step is to substitute [tex]0.4[/tex] for [tex]m[/tex], [tex]1[/tex] for [tex]y_{1}[/tex], [tex]-3[/tex] for [tex]x_{1}[/tex] in the point-slope form formula
[tex]y-1=0.4(x-(-3))[/tex]
Take out the inner bracket on the right side of the equation
[tex]y-1=0.4(x+3)[/tex]
Expand the right side of the equation
[tex]y-1=0.4x+1.2[/tex]
Add [tex]1[/tex] to both sides of the equation
[tex]y-1+1=0.4x+1.2+1[/tex]
