the value of the test statistic is approximately 5.19.we can get the answer by using formula .

what is statistic  ?

A statistic is a numerical value or measure that is calculated from a sample of data, and is used to describe or make inferences about a population. Statistics are used in various fields, including business, economics, social sciences, and natural sciences, to analyze data

In the given question,

To test the claim that the percentage of residents who favor construction is more than 49%, we can use a one-sample z-test. The test statistic can be calculated as:

z = (p - P) / √(P * (1 - P) / n)

where:

p = the sample proportion (0.53)

P = the hypothesized population proportion under the null hypothesis (0.49)

n = the sample size (800)

Substituting the given values into the formula, we get:

z = (0.53 - 0.49) / √(0.49 * 0.51 / 800) ≈ 5.19

Rounding the test statistic to two decimal places, we get:

z ≈ 5.19

Therefore, the value of the test statistic is approximately 5.19.

A dilation is not a rigid transformation, which means it has to scale the object into a different measure. So, enlarging or reducing the size of an object is a dilation.

The probability that either event will occur is 7/25

A probability is a number that reflects the chance or likelihood that a particular event will occur. The certainty of an event is 1 which is equivalent to 100% in percentage.

Probability = sample space /Total outcome

P(A or B) = P(A) +P(B) -P(A and B)

The total element = 25+5+15+5 = 50

therefore total outcome = 50

P(A) = 25/50

P(B) = 15/50

P(A and B) = 5/40

Therefore P(A and B) = 25/50+15/50 - 5/50

= 35/50 = 7/25

Marcus not getting a seat on the school bus is therefore 0.07 or 7% likely as 0.07 percent of people will not receive a seat .

The prospect of an event happening is assessed by probability. It is a number between zero and 1, where 0 denotes an improbable occurrence and 1 denotes a certain occurrence. For instance, if we flip a fair coin, the odds of obtaining heads are 0.5, or 50%, and the odds of receiving tails are also 0.5, or 50%. In each case, there are various ways to compute probability. In general, if an event has n equally possible results and k of them are favourable, the likelihood that the event will occur is: Event P = k/n . All possible outcomes are thought to be equally likely under what is referred to as the classical probability.

given

Simply put, the likelihood that Marcus won't obtain a seat on the school bus is the complement of the likelihood that he will.

By deducting the probability from 1, one can determine the complement of a probability. So:

Chance of not being seated equals one less than the likelihood of being seated.

The likelihood of not getting a seat is equal to 1 - 0.93.

The weights of the debt, preferred stock, and common equity financing are 28.6%, 30.4%, and 41.0%, respectively.

To calculate the weighted cost of capital (WACC), the proportion of each component of capital structure is needed. The weight of each component of the capital structure is determined by dividing the market value of the component by the total market value of all the components of the capital structure.

In this case, the total market value of the company's capital structure is the sum of the market value of debt, preferred stock, and common equity.

The weights for each component are calculated as follows:

Weight of debt = Market value of debt / Total market value of capital structure

= $3.3 million / ($3.3 million + $3.5 million + $4.3 million)

= 0.286 or 28.6%

Weight of preferred stock = Market value of preferred stock / Total market value of capital structure

= $3.5 million / ($3.3 million + $3.5 million + $4.3 million)

= 0.304 or 30.4%

Weight of common equity = Market value of common equity / Total market value of capital structure

= $4.3 million / ($3.3 million + $3.5 million + $4.3 million)

= 0.410 or 41.0%

These weights can be used to calculate the weighted cost of capital for Romero Company.

The probability that the first roll is a total of at least 5 and the second roll is a total of at least 4  is 0.764 or 76.4%.

The probability is the chance that an expected event occurs out of many possible events.

For two independent events happening, we use the rule of multiplication of independent events based on dice probabilities.

The event that the first roll is a total of at least 5 = A

In the event that the second roll is a total of at least 4 = B

The number of faces on each die, n = 6

The probability of event A = ³⁰/₆ = ⁵/₆

The probability of event B = ³³/₃₆ = ¹¹/₁₂

Multiplying the two probabilities, P(A) and P(B) = ⁵/₆ ​× ¹¹/₁₂

= ⁵⁵/₇₂ = 0.764

Answer: First, let's convert the room's dimensions from feet to yards, since the carpet cost is given per square yard:

17 feet = 5.67 yards (rounded to two decimal places)

16 feet = 5.33 yards (rounded to two decimal places)

Next, we can calculate the area of the room in square yards by multiplying these values:

Area = 5.67 yards × 5.33 yards = 30.23 square yards (rounded to two decimal places)

Finally, we can multiply the area by the cost per square yard to get the total cost:

Total cost = 30.23 square yards × $101/square yard = $3,056.23 (rounded to two decimal places)

Therefore, it will cost $3,056.23 to carpet the room.

Answer:

the temperature at 7 am was -36.7 degrees.

Step-by-step explanation:

Let's denote the temperature at 7 am by "x". Since the temperature increased by 8.4 C between 7 am and 11 am, we can set up the equation:

x + 8.4 = -28.3

Subtracting 8.4 from both sides, we get:

x = -36.7

Therefore, the temperature at 7 am was -36.7 degrees.

The given function does not represent the curve passing through the given points. The multiplicative rate of change of the function is 5.

A curve is a continuous, smooth line that gradually alters direction. Rather than being straight line that follows a curve may be referred to as a curve line. A curve line can be made by connecting a number of non-straight-line-lying sites. In mathematics, a curve is a geometrical object that can be described by equations, such as parametric or function equations.

The rate of change of a function is the ratio of the change in the output (y) to the change in the input (x). In this case, we can calculate the rate of change between the first two points:

Changing at what rate between (1, 10) and (2, 50)?

Y change = 50 – 10 = 40

Variation in x = 2 - 1 = 1

Rate of change equals change in y/change in x, or 40/1, or 40.

In a similar manner, we can determine how quickly the second and third points will change:

The change between (2, 50) and (3, 250) is as follows:

Changing y by 250 - 50 equals 200

Variation in x = 3 - 2 = 1

Rate of change equals change in y/change in x, which is 200/1, or 200.

Now that we have the second rate of change, we can compute the multiplicative rate of change by dividing it by the first:

Multiplicative rate of change is equal to 200/40, or 5.

The function's multiplicative rate of change is thus 5.
