Answer:
The length of the side DE is approximately 541.3 feet long.
Step-by-step explanation:
There is a trigonometry law called the law of sines, which states the sine of an angle divided by its opposite side is equivalent to the sine of all the other angles in that right triangle divided by its corresponding opposite side. You can use this law to help you solve for x. By applying the law of sines, you'll get that [tex]\frac{sin(90^{o})}{x} =\frac{sin(10^{o})}{94}[/tex] ⇒ [tex]\frac{x}{sin(90^{o})} =\frac{94}{sin(10^{o})}[/tex] ⇒ [tex]x = \frac{94*sin(90^{o})}{sin(10^o)}[/tex] ⇒ [tex]x=541.3ft.[/tex]

Billy purchased 9 types of one type and 16 types of another spinner.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
Billy bought 25 spinners.
Let x and y are the type of spinners.
Then, x + y = 25 {equation 1}
Some were $10 and some were $15.
10x + 15y = 295
Simplifying,
2x + 3y = 59 {equation 2}
Multiplying 2 to the equation 1 and subtraction the equation 2,
-y = -9
y = 9
And x = 16
Therefore, each type of spinner is 9 and 16.

A drawer contains 18 socks: 5 red socks, 10 white socks, and 3 blue socks. Without looking you draw out a sock, what is the probability of NOT getting a red sock?
Answers
Answer:
13/18 which is 72.22% chance of NOT getting a red sock
Step-by-step explanation:
As there are 18 total socks, and 13 of them are NOT red, you have a 13 out of 18 chance, or 13/18, or NOT drawing a red sock. This can be converted to the decimal, 0.7222, or percentage of 0.7222 * 100 = 72.22%

tan R = 45/28 where ∡R=58.11° and tan S = 28/45 where ∡S=38.48°
Step-by-step explanation:
The tangent of a right triangle's angle is equal to the ratio between the triangle's opposite side to its adjacent side.
tan R = 45/28
R = tan^-1(45/28)
R = 58.11°
tan S = 28/45
S = tan^-1(28/45)
S = 38.48°

Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5
If this line is given to have a slope of 3/2, let us at least put it in standard form, substituting the point ( 7, 4 ) into the equation afterwards:
y = 3/2* x + b, provided b ⇒ y - intercept,
( 4 ) = 3/2 * ( 7 ) + b,
4 = 21/2 + b,
b = 4 - 10.5,
b = -6.5
Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5

Step-by-step explanation:
First, we can add 8+5.5+8 because of the two sides which are 8 and one that is 5.5. That is 21.5.
Then, we must find the diagonal edge. To do that, we can use the pythagorean theorem. It makes a triangle, so given that a^2+b^2=c^c, we can say that 3^2+5.5^2=c^c. Using a calculator, we can find the square root of 39.25, then add it to 21.5.

Suppose that many large samples are taken from a population, and the
sample proportions center around 0.58. Which of the following is most likely
to be the population parameter?
O A. 0.68
OB. 0.58
O C. 0.78
O D. 0.48
Answers
Answer:
A- 0.68
Step-by-step explanation:
0.58 is most likely to be the population parameter, since the sample proportions center around this value.
Option B is the correct answer.
We have,
When many large samples are taken from a population, the sample proportions should converge to the population proportion.
If the sample proportions center around a certain value, that value is likely to be a good estimate of the population proportion.
In this case,
Since the sample proportions center around 0.58, it is likely that the population proportion is also around 0.58.
Therefore,
0.58 is the most likely population parameter.
