Hello there! I am EnjoyingLife, and I hope you find my answer helpful :)
The first step is to subtract 3 from both sides (remember the Golden Rule of Algebra: Whatever we do to one side, we do to the other)
\(\tt{4x+3-3=10-3}\)
\(\tt{4x=10-3}\)
\(\tt{4x=7}\)
Divide both sides by 4 in order to isolate x:

if a ray of light strikes mirror 1 with an angle of incidence of 41 ∘ , find the angle of reflection of the ray when it leaves mirror 2.
The angle of reflection for the ray leaving mirror 2 will be 41 degrees, as this is equal to the angle of incidence for the ray striking mirror 2.
The angle of incidence is the angle between the incoming ray and the surface of the mirror, and the angle of reflection is the angle between the reflected ray and the surface of the mirror.
In the given scenario, a ray of light strikes mirror 1 with an angle of incidence of 41 degrees.
The angle of reflection can be calculated using the law of reflection, which states that the angle of incidence is equal to the angle of reflection.
Therefore, the angle of reflection of the ray when it leaves mirror 1 will be 41 degrees.
However, the ray of light continues its journey and strikes mirror 2.
When this happens, the angle of incidence is the angle between the reflected ray from mirror 1 and the surface of mirror 2.
The angle of reflection for the ray leaving mirror 2 can be calculated using the same law of reflection.
The angle of reflection will be equal to the angle of incidence, which is 41 degrees.
The angle of reflection is a crucial concept in understanding the reflection of light and is used in various applications such as mirrors, prisms, and lenses.

The average height of a group of student is 68 inches with a standard deviation of 3 inches. The average shoe size is in this same group is 11 with a standard deviation of 2 . If the covariance between them is 3.732, what is the variance of Height - ShoeSize?
The variance of the difference between height and shoe size is approximately 5.536.
Given:
Average height (H) = 68 inches
Standard deviation of height (σH) = 3 inches
Average shoe size (S) = 11
Standard deviation of shoe size (σS) = 2
Covariance (Cov) between height and shoe size = 3.732
To calculate the variance of the difference between height and shoe size (Var(H - S), we can use the following formula:
Var(H - S) = Var(H) + Var(S) - 2 Cov(H, S)
First, let's calculate the variances of height and shoe size:
Var(H) = (σH)^2 = 3^2 = 9
Var(S) = (σS)^2 = 2^2 = 4
Now, substitute the values into the formula:
Var(H - S) = 9 + 4 - 2 3.732
Calculating the expression:
Var(H - S) = 9 + 4 - 2 3.732
= 9 + 4 - 7.464
= 5.536
Therefore, the variance of the difference between height and shoe size is approximately 5.536.

The clock minutes rotate 270 degrees in 45 minutes.
How to calculate the angular size of a clock's handsWhile rotating, the clock's hands are seen to move at a speed of six degrees per minute.
The number of degrees for a clock minute is solved by
60 minutes = 360 degrees
1 minute = ?
cross multiplying
60 * ? = 360
? = 360 / 60
? = 6
hence 1 minute is 6 degrees
The formula to use to get the calculation is multiplying the number of minutes by 6
Number of degrees in 45 minutes = 45 * 6

Television today are sold with standard aspect ratios that means the ratio of the width to the height is 6:9 if nick as a wall big enough to hold a TV that is 70 inches wide how tall will the TV be round your answer to the nearest 10th
Answer:
The height of the TV to the nearest tenth = 105.00
Step-by-step explanation:
Ratio of width to height = 6 : 9
Find the height of a TV when the width is 70 inches
Let
The height of the TV = x
6 : 9 = 70 : x
6 / 9 = 70 / x
Cross product
6 * x = 9 * 70
6x = 630
x = 630 / 6
x = 105.00 to the nearest tenth
The height of the TV to the nearest tenth = 105.00

= Find (v). (Round your answer to one decimal place.) ∣v∣=153.6 Find the true course and the ground speed (in mi ih) of the plane. (Round your answers to one decimal place.)
The question asks for the velocity vector of a plane relative to the ground, given the velocity of the plane and the velocity of the wind. It also requires finding the magnitude of the velocity vector and determining the true course and ground speed of the plane.
The velocity vector of the plane relative to the ground can be obtained by adding the velocity of the plane to the velocity of the wind. Let's denote the velocity of the plane as v_plane and the velocity of the wind as v_wind. Adding these vectors, we get v = v_plane + v_wind.
To find the magnitude of the velocity vector (∣v∣), we can calculate the length of the resulting vector. The magnitude of a vector is the length or size of the vector. In this case, the magnitude of the velocity vector is given as 153.6 (rounded to one decimal place).
To determine the true course and ground speed of the plane, we need to analyze the components of the velocity vector. The true course refers to the direction in which the plane is actually moving relative to the ground. The ground speed represents the speed of the plane relative to the ground, measured in miles per hour (mph). The specific values for the true course and ground speed cannot be determined without additional information or equations related to the problem.
In summary, the velocity vector of the plane relative to the ground is obtained by adding the velocity of the plane to the velocity of the wind. The magnitude of the velocity vector is given as 153.6. However, without further information or equations, we cannot determine the true course and ground speed of the plane.

Consider the line in the coordinate plane that passes through the point (-7, -3) and the origin. Find the slope of a line perpendicular to the line described.
A) -1/3
B) -3/7
C) -7/3
D) 3/7
The line passing through (-7, -3) and the origin has a slope of 3/7. A line perpendicular to it has a slope of -7/3.
The line passing through the point (-7, -3) and the origin has slope equal to the ratio of the change in the y-coordinate to the change in the x-coordinate as we move from the origin to the point (-7, -3). This is given by:
slope = (change in y-coordinate) / (change in x-coordinate)
= (-3 - 0) / (-7 - 0)
= 3/7
So the slope of the given line is 3/7.
A line perpendicular to this line will have a slope that is the negative reciprocal of 3/7. That is,
slope of perpendicular line = -1 / (3/7) = -7/3
Therefore, the answer is (C) -7/3.

Solve the equation -7x - 9 = 19 x =?
Answer:-4
Step-by-step explanation:
-4 x -7 = 28
28-9=19
Answer:
x=-4
Step-by-step explanation:
We are given the equation:
-7x-9= 19
We want to solve for x. Therefore, we must isolate x on one side of the equation.
9 is being subtracted. The inverse of subtraction is addition. Add 9 to both sides of the equation.
-7x-9+9= 19+9
-7x= 28
x is being multiplied by -7. The inverse of multiplication is division. Divide -7 on both sides.
-7x/-7=28/-7
x= 28/-7
x= -4
Let’s check our solution. Plug -4 in for x and solve.
-7x-9=19
-7(-4)-9=19
28-9=19
19=19
This checks out, so we know our solution is correct.
The solution to the equation -7x-9=19 is x= -4

The researcher collected a random sample of 1250 post graduate students from 3 big universities in sydney and asked them to fill in a questionnaire. Are the data collected by the researcher considered as primary or secondary dat? Explain.
The researcher's collection of data from post graduate students through a questionnaire makes it primary data.
The data collected by the researcher are considered as primary data. Primary data refers to original data that is collected firsthand by the researcher for a specific research purpose.
In this case, the researcher collected the data directly from the post graduate students through the questionnaire for the purpose of studying their behaviors in mobile phone usage.
Primary data is considered more reliable and accurate than secondary data because it is collected specifically for the research question at hand.
The researcher has control over the data collection process and can ensure that the data is relevant and accurate. However, primary data collection can be time-consuming and expensive compared to using secondary data.
In contrast, secondary data refers to data that has already been collected by someone else for a different purpose. Examples of secondary data include government reports, academic journals, and market research studies.
