if the station stocks 600 gallons at the start of the week, what is the probability that thry sell more than 250 gallons
Answers
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.

Geometry parallel lines (please solve and explain)
Answers
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°

Answers
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.

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.
Answers
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
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?
Answers
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.

Answers
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.

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

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.
The amount of sunshine a plant receives determines how large it will become. The dependent variable changes when the independent variable changes. To get valid findings from this experiment, all other factors must be kept constant or under control.
