Answer:
see explanation
Step-by-step explanation:
∠ 1 and ∠ 2 are corresponding angles and are congruent , then
7x - 27 = 4x + 18 ( subtract 4x from both sides )
3x - 27 = 18 ( add 27 to both sides )
3x = 45 ( divide both sides by 3 )
so
∠ 1 and ∠ 2 = 7x - 27 = 7(15) - 27 = 105 - 27 = 78°
∠ 2 and ∠ 3 are corresponding angles and are congruent , then
∠ 3 = 78°
∠ 3 and ∠ 4 are same- side interior angles and sum to 180° , that is
78 + 4y + 2 = 180
4y + 80 = 180 ( subtract 80 from both sides )
4y = 100 ( divide both sides by 4 )
y = 25
thus
∠ 4 = 4y + 2 = 4(25) + 2 = 100 + 2 = 102°
in conclusion
x = 15 , y = 25 , ∠ 1 = 78° , ∠ 4 = 102°

What is a triangle?In Mathematics, a triangle can be defined as a two-dimensional (2D) geometric shape that comprises three (3) sides, three (3) vertices and three (3) angles only.
Furthermore, the sum of the angles in a triangle is equal to 180. This ultimately implies that, we would sum up all of the angles as follows;
m∠D + m∠E + m∠F = 180
Substituting the given parameters into the mathematical expression, we have the following;
(11x)° + (25x)° + (9x°) = 180°
(36x)° + (9x°) = 180° or (11x)° + (34x°) = 180°
45x = 180

a small apartment has a 11ft by 11ft bedroom, a 4ft by 6ft bathroom, and a single multi-use 15ft by 16ft living room/kitchen. what is the total square footage (area) of the apartment?
The total square footage (area) of the apartment is 385 square feet.
The total square footage, also known as the area, of an apartment is a measure of how much space the apartment has.
First, let's find the area of the 11ft by 11ft bedroom. To do this, we multiply the length and the width of the room. In mathematical terms, the area of a rectangle is equal to the length times the width. So, for the bedroom, the area is
=> 11ft * 11ft = 121 square feet.
Next, let's find the area of the 4ft by 6ft bathroom. The formula for the area of a rectangle is still the same, so the area of the bathroom is
=> 4ft * 6ft = 24 square feet.
Finally, we'll find the area of the multi-use living room/kitchen, which is 15ft by 16ft. The area of this room is
=> 15ft * 16ft = 240 square feet.
Now that we have the area of each room, we can add them together to find the total area of the apartment. So, the total area is
=> 121 square feet + 24 square feet + 240 square feet = 385 square feet.

a salesperson is paid $300 per week plus 15% commission on her weekly sales of x dollars. find a linear function that represents her total weekly pay w in terms of x.
Answer:
w = 300 + 0.15x
Step-by-step explanation:
Let x = weekly sales
Since there is a fixed remuneration of $300, that will be a constant in the linear equation
15% = 15/100 = 0.15 in decimal
15% commission on x dollars of sales = 0.15x
Therefore total weekly pay, w, in terms of x
w = 300 + 0.15x

consider that in 2019 u.s. household income had a mean of $64,000, a standard deviation of $12,000, and a frequency distribution that was mound-shaped and symmetric. determine the z-score for someone with an income of $40,000. group of answer choices -3.00 -2.00 2.00 3.00
A z-score of -2 means that the income of $40,000 is 2 standard deviations below the mean income of $64,000.
The z-score is a standard measure of how many standard deviations a data point is away from the mean. To determine the z-score, we need to use the formula:
z = (x - μ) / σ
Where x is the data point of interest ($40,000), μ is the mean ($64,000), and σ is the standard deviation ($12,000).
Substituting the values:
z = (40000 - 64000) / 12000
z = -2
Therefore, the z-score for someone with an income of $40,000 is -2.
In conclusion, a z-score of -2 means that the income of $40,000 is 2 standard deviations below the mean income of $64,000.

People cannot tell if infrared lights have been turned on in a dark environment. A good method to test this theory is to ask a group of people if an infrared light had been turned on while they were in a room that was lit by infrared radiation.
The experimenter's measurement of the control variable is the independent variable. Independent and dependent variables are the two different categories. These two things might be related in a cause-and-effect manner. The dependent variable is impacted by changes to the independent variable.
Dependent variables are variables that are examined or evaluated as a part of a study.Participants' test scores would be the dependent variable in a study looking at how tutoring affects test results because that is what is being measured.
Two of the most crucial terms in scientific study are "causing" and "effect. It is essential to recognise the independent and dependent variables.A "complex hypothesis" is one that describes a relationship between two or more variables. This equation, as its name implies, has a minimum of two independent variables and a minimum of two dependent variables. These illustrations can aid in your understanding of a challenging theory.
To find out if a theory holds up under inspection, anyone can conduct an experiment. This technique enables you to explain why a theory is unsupported by the evidence. Experimental data, however, can sometimes be interpreted in a nebulous or unclear way.

if the station stocks 600 gallons at the start of the week, what is the probability that thry sell more than 250 gallons
The exact probability cannot be determined without additional information such as the average daily sales rate.
To find the probability of selling more than 250 gallons, we need to find the cumulative distribution function (CDF) of the number of gallons sold, which is the probability of selling a certain amount or less. Since the amount sold follows a Poisson distribution with an average of 200 gallons, the CDF can be calculated using the Poisson cumulative distribution function formula:
P(X <= x) = e^(-μ) * (μ^x) / x!
Where μ is the average number of gallons sold and x is the amount sold. To find the probability of selling more than 250 gallons, we subtract the CDF for 250 gallons or less from 1. This gives us the probability of selling more than 250 gallons.

The value of sinθ for the condition is 0.822.
What are trigonometric functions?Simply put, trigonometric functions—also referred to as circular functions—are the functions of a triangle's angle. This means that these trig functions provide the relationship between the angles and sides of a triangle. Sine, cosine, tangent, cotangent, secant, and cosecant are the fundamental trigonometric functions.
Given the identity cos²θ + sin²θ = 1
and cosθ = 0.57 where 0 < θ < π/2
the value of θ varies from 0 to π/2 which means θ is in the first quadrant.
substitute the value in identity,
cos²θ + sin²θ = 1
(0.57)² + sin²θ = 1
sin²θ = 1 -0.3249
sinθ = √0.6751
sinθ = 0.8216

Suppose your office gives you $200 to buy computer disks. The 550-MB disks cost $7 each. The 650-MB disks cost $8 each. Write the inequality that describes how many of each kind of disk you can buy.
Answer:
7x + 8y ≤ 200
Step-by-step explanation:
Let's say x is the number of 550-MB disks and y is the number of 650-MB disks. Then, the cost of x 550-MB disks is 7x dollars, and the cost of y 650-MB disks is 8y dollars.
The total cost cannot exceed $200, so we have:
7x + 8y ≤ 200
This inequality represents the maximum number of disks of each type that can be bought with the budget of $200.

the meese's company claims that you should find an average of 240 240 orange candies in the jumbo bag of 600 600 candies. the orange candies are normally distributed and have a standard deviation of 6 6 candies. if you sampled a number of these bags and found between 225 225 and 250 250 orange pieces, how would you write this interval as a probability?
The probability of finding between 225 and 250 orange pieces in a sample of jumbo bags is 0.7966.
The probability of finding between 225 and 250 orange pieces in a sample of jumbo bags can be written using the standard normal distribution. This is done by calculating the z-score of the interval between 225 and 250 and then calculating the probability of getting a value between the two given points.
The formula for calculating the z-score is (x-μ)/σ, where x is the value of the interval, μ is the mean (240) and σ is the standard deviation (6). The z-score of the given interval is equal to (-2.5 - (-5))/6 = 0.83.
The probability of getting a value between 225 and 250 is equal to the area under the normal curve between the two given points. This area is equal to the cumulative probability of the z-score of 0.83, which is equal to 0.7966.
Therefore, the probability of finding between 225 and 250 orange pieces in a sample of jumbo bags is 0.7966.
