The correct answer is d. µ ≠ 300. The alternative hypothesis (H1) is typically the complement of the null hypothesis (H0) and represents the possibility of observing a statistically significant difference between two groups or variables.

In this case, since the null hypothesis (H0) is µ = 300, the alternative hypothesis (H1) could be µ ≠ 300, which means that there is a significant difference between the population mean and the hypothesized value of 300.

Therefore, the correct answer is d. µ ≠ 300.

The value of x will be 0 and x = 5. The correct option is A.

The x-intercept is the point at which a line intersects the x-axis, and the y-intercept is the point at which the line intersects the y-axis.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the x-intercept(s) of the function is the quantity of 5x² - 25x.

The value of the x-intercept will be calculated as,

5x² - 25x = 0

5x( x -25) = 0

5x = 0 and x - 5 = 0

x = 0  and x = 5

Therefore, the value of x will be 0 and x = 5. The correct option is A.

Answer:

it's x = 5

Step-by-step explanation:

got it right on the test.

Answer: The answer is > because it means greater than, and -2.7 is closer to becoming a positive than -3.6.

The correct system of equations is A. x+y=1212 and x-y=518.

Let us assume the two numbers to be x and y. Based on the first statement, the equation will be:

x + y = 1212

Based on the second statement, the equation will be:

x - y = 518

Using the equation to find the value of x and y

Adding these two equations. We get -

2x = 1730

x = 1730 ÷ 2

Performing division

x = 865

Keeping the value of x in first equation to find the value of y

y = 1212 - 865

Performing subtraction

y = 347

If  your hotel is stories tall and the average story is feet high, the distance is  69 feet.

We can solve this problem using similar triangles. Let's call the distance between you and your hotel "x".

First, we need to determine the height of the building in front of you. Since we know it is five stories tall, and the average story is 10 feet high, its total height is 5 * 10 = 50 feet.

Now, we can use the similar triangles formed by the buildings and your line of sight to set up a proportion:

x / (h + 50) = 60 / h

where "h" is the height of the five-story building, and "h + 50" is the total height of the building and its billboard.

We can cross-multiply to get:

x * h = 60 * (h + 50)

Expanding the right side, we get:

x * h = 60h + 3000

Subtracting 60h from both sides, we get:

x * h - 60h = 3000

Factoring out the h, we get:

h * (x - 60) = 3000

Dividing both sides by h, we get:

x - 60 = 3000 / h

Substituting in the known values, we get:

x - 60 = 3000 / (10 * 32)

Simplifying, we get:

x - 60 = 9.375

Adding 60 to both sides, we get:

x = 69.375

x = 69 feet

Therefore, you are approximately 69 feet away from your hotel.

The solution of the limits are

1. f(x) = {(1/x-1) if x<1; (x³-2x+5) if x>=1 is does not exist

2. f(x) = {(3-x) if x<2; 2 if x = 2; x/2 if x>2 is 1

3. f(x) = {1-x^2 if x<1; 2 if x>=1 is does not exitst

4. f(x) = {(2x+1) if x<=-1; 3x if -1=1 is 1

5. f(x) = {(x-1)^2 if x<0; (x+1)^2 if x>=0 is 0

f(x) = {(1/x-1) if x<1; (x³-2x+5) if x>=1 is 1

To evaluate this function, we need to determine the limit of the function as x approaches 1 from both the left and the right sides.

When x approaches 1 from the left side (x<1), the function becomes f(x) = 1/(x-1). As x gets closer to 1 from the left side, the denominator (x-1) becomes smaller and smaller, causing the entire fraction to approach infinity. Therefore, the limit of f(x) as x approaches 1 from the left side is infinity.

When x approaches 1 from the right side (x>=1), the function becomes f(x) = x³-2x+5. As x gets closer to 1 from the right side, the function approaches 4. Therefore, the limit of f(x) as x approaches 1 from the right side is 4.

Since the limit of the function from the left and right sides are different, the limit of the function as x approaches 1 does not exist.

f(x) = {(3-x) if x<2; 2 if x = 2; x/2 if x>2

To evaluate this function, we need to determine the limit of the function as x approaches 2 from both the left and the right sides.

When x approaches 2 from the left side (x<2), the function becomes f(x) = 3-x. As x gets closer to 2 from the left side, the function approaches 1. Therefore, the limit of f(x) as x approaches 2 from the left side is 1.

When x approaches 2 from the right side (x>2), the function becomes f(x) = x/2. As x gets closer to 2 from the right side, the function approaches 1. Therefore, the limit of f(x) as x approaches 2 from the right side is 1.

Since the limit of the function from the left and right sides are the same, the limit of the function as x approaches 2 exists and is equal to 1.

f(x) = {1-x² if x<1; 2 if x>=1

To evaluate this function, we need to determine the limit of the function as x approaches 1 from both the left and the right sides.

When x approaches 1 from the left side (x<1), the function becomes f(x) = 1-x². As x gets closer to 1 from the left side, the function approaches 0. Therefore, the limit of f(x) as x approaches 1 from the left side is 0.

When x approaches 1 from the right side (x>=1), the function becomes f(x) = 2. As x gets closer to 1 from the right side, the function remains constant at 2. Therefore, the limit of f(x) as x approaches 1 from the right side is 2.

Since the limit of the function from the left and right sides are different, the limit of the function as x approaches 1 does not exist.

f(x) = {(2x+1) if x<=-1; 3x if -1=1

To evaluate this function, we need to determine the limit of the function as x approaches -1 from both the left and the right sides.

When x approaches -1 from the left side (x<-1), the function becomes f(x) = 2x+1. As x gets closer to -1 from the left side, the function approaches -1. Therefore, the limit of f(x) as x approaches -1 from the left side is -1.

When x approaches -1 from the right side (-1<x<1), the function becomes f(x) = 3x. As x gets closer to -1 from the right side, the function approaches -3. Therefore, the limit of f(x) as x approaches -1 from the right side is -3.

Since the limit of the function from the left and right sides are different, the limit of the function as x approaches -1 does not exist.

f(x) = {(x-1)² if x<0; (x+1)² if x>=0

To evaluate this function, we need to determine the limit of the function as x approaches 0 from both the left and the right sides.

When x approaches 0 from the left side (x<0), the function becomes f(x) = (x-1)². As x gets closer to 0 from the left side, the function approaches 1. Therefore, the limit of f(x) as x approaches 0 from the left side is 1.

When x approaches 0 from the right side (x>=0), the function becomes f(x) = (x+1)². As x gets closer to 0 from the right side, the function approaches 1. Therefore, the limit of f(x) as x approaches 0 from the right side is 1.

Since the limit of the function from the left and right sides are the same, the limit of the function as x approaches 0 exists and is equal to 1.

4. 281.25 mg

Step-by-step explanation:

The length of the shortest straight  is approximately 28.01 ft.

What is the right triangle?

A right triangle is" a type of triangle that has one angle measuring 90 degrees (a right angle). The other two angles in a right triangle are acute angles, meaning they are less than 90 degrees".

To find the length of the shortest straight beam,we can use the Pythagorean theorem.

Let's denote the length of the beam as L and  a right triangle formed by the beam, the wall, and the ground. The wall is 28 ft tall, and the distance from the wall to the building is 1 ft.

Using the Pythagorean theorem,

\(L^2 = (28 ft)^2 + (1 ft)^2\)

Simplifying the equation:

\(L^2 = 784 ft^2 + 1 ft^2\\ L^2 = 785 ft^2\)

\(L = \sqrt{785}ft\)

Calculating the value of L:

L ≈ 28.01 ft

Therefore, the length of the shortest straight beam  is approximately 28.01 ft.

Component 3 must be started on day 197 to meet the delivery date of day 200.

To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.

(a) Backward schedule:

Operation    |  Work Center  |  Time (hours)  |  Start Day

--------------------------------------------------------

Final Assembly |   Work Center 1  |        1       |     200

Sub-assembly 1 |   Work Center 2  |        2       |     199

Component 4     |   Work Center 3  |        3       |     197

Component 2     |   Work Center 4  |        4       |     196

Component 3     |   Work Center 5  |        3       |     ????

(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.

From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.

Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.

Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

The solution is: the value of |A+3|/(A-3) IF a=-17 is: - 7/10.

Here, we have,

given that,

A = -17

then we have to find |A+3|/(A-3)

now we know,

The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.

so, we have,

For any real number x, if x > 0 then |x| = x and if x < 0 then |x| = -x. In this case, x < 0

so, |A+3| =  |-17 + 3|

now,  |-17 + 3| = -(-14) = 14.

and, (A-3) = -17 - 3 = -20

so, |A+3|/(A-3) = 14/ -20

                       = - 7/10

Hence, The solution is: the value of |A+3|/(A-3) IF a=-17 is: - 7/10.

In a binomial probability distribution, there are two possible outcomes for each trial, usually labeled as success (S) or failure (F), with probabilities p and (1-p), respectively. The random variable x represents the number of successes in the given number of trials, n.

The variance measures the spread or variability of a probability distribution. For a binomial distribution, the formula to calculate the variance is Var(x) = np(1-p).

The term np represents the mean or expected value of the binomial distribution, which is the product of the number of trials, n, and the probability of success, p.

The term (1-p) represents the probability of failure, or the complement of p. Multiplying np by (1-p) accounts for the variability in the number of failures.
