Answer:
-24
Step-by-step explanation:
to find the answer to this you must find out what would make the equation constant
everytime the x goes up by 3 the y goes down by 6
so every time the x goes up by 1 the y goes down by 2
so
you would subtract 5 * 2 (or 10) to -14
-14 - 10 = -24

Answers
Answer:
13500 ft²
Step-by-step explanation:
Area of rectangle:We can find the width of the rectangle using Pythagorean theorem.
AD² + DC² = AC²
180² + DC² = 195²
32400 + DC² = 38025
DC² = 38025 - 32400
= 5625
DC = √5625
= 75 ft
length = 75 ft
Width = 180 ft
\(\sf \boxed{\text{\bf Area of rectangle = length * width}}\)
= 75 * 180
= 13500 ft²
state the null and alternative hypotheses for the following conjecture. the average age of a senior surgical resident in the united states is less than 30.8 years old.
Answers
The null hypothesis (H0) states that the average age is equal to or greater than 30.8 years, while the alternative hypothesis (Ha) states that the average age is less than 30.8 years.
In hypothesis testing, we set up the null hypothesis (H0) and the alternative hypothesis (Ha) to investigate a claim or conjecture. In this case, the conjecture is that the average age of a senior surgical resident in the United States is less than 30.8 years old.
The null hypothesis (H0) assumes that the average age is equal to or greater than 30.8 years, and any difference observed in the sample is due to random chance or sampling variability. Therefore, the null hypothesis can be stated as:
H0: The average age of senior surgical residents in the United States is greater than or equal to 30.8 years.
The alternative hypothesis (Ha) represents the claim or the opposite of the null hypothesis. In this case, the alternative hypothesis states that the average age is less than 30.8 years, indicating that there is a significant difference or evidence against the null hypothesis. Therefore, the alternative hypothesis can be stated as:
Ha: The average age of senior surgical residents in the United States is less than 30.8 years.

P→ P'(3,-2) for (x,y) → (x-2,y) and reflection line y = 4. Find the coordinates of P.
Answers
Answer: We can first reflect point P' = (3,-2) across the line y=4 to obtain the image point P'' as follows:
The y-coordinate of P' is -2 which is 6 units away from the line y=4. Therefore, its reflection across the line y=4 will have a y-coordinate of 4+6 = 10.
The x-coordinate of P' is 3. Since the reflection line y=4 is the midpoint of P' and its reflection, the x-coordinate of P'' is 2 units to the left of the reflection line. Therefore, the x-coordinate of P'' is 3-2 = 1.
So, the coordinates of P'' are (1,10).
To obtain the coordinates of point P, we need to apply the transformation (x,y) → (x-2,y) to P''. Therefore, we get:
P = (1-2,10) = (-1,10)
Therefore, the coordinates of point P are (-1,10).

to use a binomial distribution to approximate the count of successes in an srs, why do we require that the sample size n be no more than 10% of the population size n?
Answers
When the 10% criterion is met, we can use a binomial distribution to approximate the number of successes in a simple random sample (SRS) (as a simple random sample selects the trials without replacement).
The sample must be less than 10% of the population in order to satisfy the 10% requirement. It is fair to presume that the trials are independent because the sample is so much smaller than the population (even though the sampling occurred without replacement).
This suggests that the sample size n in this situation must be less than 10% of the population size NN.
This is the reason why 10% condition should be met.
In a binomial probability distribution, the number of successes in a series of n experiments is represented as either success or failure (probability q = 1 p), depending on the outcome's boolean value. A Bernoulli trial or experiment is another name for a single success or failure test, while a Bernoulli process is another name for a sequence of results.

By reducing the denominator each time, the given real-number's \(1-\frac{1}{1-\frac{1}{1-\frac{1}{2}}}\)simplification yields the answer of 2, which is 2.
What are real-numbers?They display the value of something actual, which is why they are not referred to as "Real". All numbers are part of the real number system, which is a collection of all numbers. Every number you have ever used, ever since you were old enough to count, is a component of the real number system. The real number system divides the numbers into two fundamental groups. Both sets of numbers fall into two categories: rational and irrational. Natural numbers, whole numbers, integers, ratios of two integers, decimal numbers that terminate, and decimal numbers with recurrent digit patterns all fall within the category of rational numbers.
Given expression is: \(1-\frac{1}{1-\frac{1}{1-\frac{1}{2}}}\)

(Type your answer in slope-intercept form.)
Answers
Answer:
y = -4x + 16
Step-by-step explanation:
The slope of the given line is -4
when two lines are parallel, their slopes are equal
That means the slope of the second line is -4 too
Thus, we have to use the point-slope form to write the equation
That will be
y-y1 = m(x-x1)
y-8 = -4(x-2)
y -8 = -4x + 8
y = -4x + 8+8

the number of cookies in a shipment of bags are normally distributed, with a mean of 64 and a standard deviation of 4. what percent of bags of cookies will contain between 64 and 68 cookies?
Answers
The percentage of bags of cookies that will contain between 64 and 68 cookies is approximately 18.23%.The number of cookies in a shipment of bags is normally distributed, with a mean of 64 and a standard deviation of 4.
What percentage of bags of cookies will contain between 64 and 68 cookies
When X is normally distributed with mean µ and standard deviation σ, the z-score formula can be used to find the probability that X is between two values.
Z = (X - µ) / σ
First, we convert both 64 and 68 to z-scores:
Z for 64 cookies = (64 - 64) / 4 = 0Z for 68 cookies = (68 - 64) / 4 = 1
Next, we find the probability that X is between these two z-scores using a standard normal distribution table or calculator:
Prob (0 < Z < 1) = 0.3413 - 0.5(0) - 0.159
= 0.1823
So, the percentage of bags of cookies that will contain between 64 and 68 cookies is approximately 18.23%.

Step-by-step explanation:
4T+48 = T+282
The length of the football field is 360 feet.
The length of the tennis court is 78 feet.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The length of a football field including the end zones is 48 feet longer than four times the length of a tennis court.
And, It is also 282 feet longer than a tennis court.
Let the length of the tennis court = x
So, The length of the football field = 48 + 4x
Here, The length of the football field is 282 feet longer than a tennis court.
So, We get;
⇒ 48 + 4x = 282 + x
⇒ 4x - x = 282 - 48
⇒ 3x = 234
⇒ x = 78
Thus, The length of the football field = 48 + 4x
= 48 + 4×78
= 48 + 312
= 360 feet
The length of the tennis court = x
= 78 feet
