Step-by-step explanation:
The hypotenuse side XY of given right angle at Z is [tex]5\sqrt{2}[/tex].
Given that in triangle XYZ :
∠X=45°
∠Y=45°
XY=5
And right angled at Z, that is, ∠Z=90°.
Since, ∠X=∠Y=45°
Therefore, XZ=YZ=5
Now,
[tex]\sin \theta = \dfrac{hypotenuse}{opposite}[/tex].
Here, θ=45°.
Therefore,
[tex]\sin \theta=\dfrac{5}{XY}\\\\\sin 45\°^=\dfrac{5}{XY}\\\dfrac{1}{\sqrt{2} } =\dfrac{5}{XY}\\\\XY=5\sqrt{2}[/tex]
Thus, the side XY=[tex]5\sqrt{2}[/tex].

13. Each side of a rhombus is 14 in. long. Two of the sides form a 60 angle. Find the area of the rhombus. Round your answer to the nearest square inch.
Answers
Answer:
170 in²
Step-by-step explanation:
Given that :
Side, a = 14 in
Angle formed =? 60°
Take height, = l
The ratio of height to side = Sine of the angle formed
l /s = Sine 60°
Sin 60 = sqrt(3)/2
l/s = sqrt(3)/2
l = sqrt(3)/2 * s
s = 14
l = 14 * sqrt(3)/2
l = 7sqrt(3)
Area of rhombus :
l * s
7sqrt(3) * 14
= 169.74097
= 169.74 in²
= 170 (nearest square inch)
A bag contains 8 red marbles, 12 blue marbles, and 17 green marbles. If one marble is randomly selected
from the bag, what is the probability that the marble is red or green?

Answers
Answer:
There are 37 marbles.
Probability = (# favorable outcomes) / (# total outcomes)
P (r or g) = 25/37
3) 25/37
Step-by-step explanation:
The probability of red or green marbles is 0.676
How to determine the probability?The given parameters are:
8 red marbles, 12 blue marbles, and 17 green marbles
The number of red or green marbles is:
Red or Green = 8 + 17
Evaluate
Red or Green = 25
The probability of red or green marbles is:
P = 25/(8 + 12 + 17)
Evaluate
P = 0.676
Hence, the probability of red or green marbles is 0.676

Explain how to solve the equation 2x+4=-6x+38 in complete sentences. Your response needs to be a paragraph in length and use appropriate math vocabulary
Answers
Answer:
×=17/4
Step-by-step explanation:
The equation 2x+ 4=-6x+38
First of all you collect like terms by moving the number -6x over to the left hand side which then becomes +6x as it crosses the equal to sign, likewise you move +4 over to the right hand side which then becomes -4. The equation is now 2x+6x=38-4, which when solved gives 8x=34. X is then made subject of formula by dividing both sides by 8 therefore x=34/8 which when reduced to the lowest term is 17/4

The number of wins for a high school football team is measured for the season. When the team plays at home, it is generally believed that they will win. Comparing the location of the game and the number of wins, a correlation coefficient of −0.91 is calculated. What would this imply about the football team winning at home?
1. The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.
2.The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, but causation cannot be determined.
3.The scatter plot would not be represented by a line of best fit with a negative slope. There is a weak correlation between the football team playing at home and winning.
4. There is no causation and almost no correlation between the football team playing at home and winning.
Answers
Correlation coefficients are used to solve this question, leading to the following answer:
1. The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.
-----------------------------------
Correlation coefficients:
They measure the relationship between variables, the closer |r| is to 1, the stronger the relationship is.
If the coefficient is positive, there is a positive relationship(both variables change in the same direction)If the coefficient is negative, there is a negative relationship(the variables change in opposite directions).-----------------------------------
In this question:
r = -0.91
Negative, so opposite directions, which can be explained as for example, the more the team travels(plays away games), the less games it wins.|r| = 0.91, which is quite close to 1, so a significant relationship.Negative relation means that the scatter plot would be represented by a straight line with a negative slope, and the correct answer is:1. The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.

to solve this system of equations, first, we substitute the equation [tex]y = 3x + 10[/tex] to the y variable in the equation [tex]2x-3y = -6[/tex]. Therefore, we get:
[tex]2x - 3(3x+10)=-6[/tex]
now, we simplify by multiplying -3 to the variables inside the parenthesis, which, in short, is also called the distributive property. thus, we get:
