Answer:

Integers: 32,33,34,35

Step-by-step explanation:

Consecutive means back-to-back, with a difference of 1

Therefore this can be represented with the following equation (where x is the first number), and we can set this equal to the sum

\(x+(x+1)+(x+2)+(x+3)=134\\4x+6=134\\4x=128\\x=32\)

Therefore since x = 32, all four integers are:

\(32,33,34,35\)

If we check this, we can see that their sum equals to 134

\(32+33+34+35 = 134\)

Step-by-step explanation:

Subtract the amount of money you payed to how much the cost actually was to get your answer.

The probability of having at least 1 hurricane per year in the coastal city, based on the given information and assuming a Poisson distribution, is approximately 0.9502 or 95.02%. This means that there is a high likelihood of experiencing at least one hurricane in a year in the coastal city.

Let λ be the average number of hurricanes per year in the coastal city. We have that it is twice as likely to have 2 hurricanes per year than 3, we can set up the following relationship:

P(X = 2) = 2 * P(X = 3)

In a Poisson distribution, the probability mass function (PMF) is given by:

P(X = k) = (e^(-λ) * λ^k) / k!

Using this PMF, we can express the relationship as:

(e^(-λ) * λ^2) / 2 = 2 * (e^(-λ) * λ^3) / 3

Simplifying, we get:

2 * λ^2 = (2/3) * λ^3

Dividing both sides by λ^2 and rearranging:

2 = (2/3) * λ

λ = 3

So, the average number of hurricanes per year, λ, is 3.

To compute the probability of having at least 1 hurricane per year, we can calculate the complementary probability of having 0 hurricanes and subtract it from 1.

P(X ≥ 1) = 1 - P(X = 0)

Using the Poisson PMF, we can calculate:

P(X = 0) = (e^(-3) * 3^0) / 0! = e^(-3)

Therefore,

P(X ≥ 1) = 1 - e^(-3)

Using the exponential function value of e^(-3) ≈ 0.0498, we can compute:

P(X ≥ 1) ≈ 1 - 0.0498 ≈ 0.9502

So, the probability of having at least 1 hurricane per year is approximately 0.9502 or 95.02%.

The volume of the triangular prism is 216 cubic meters.

To find the volume of a triangular prism, we need to multiply the area of the triangular base by the length of the prism.

Calculate the area of the triangular base.

The base of the triangular face is given as 8 meters, and the height is 9 meters. We can use the formula for the area of a triangle: area = (1/2) * base * height.

Plugging in the values, we get:

Area = (1/2) * 8 meters * 9 meters = 36 square meters.

Multiply the area of the base by the length of the prism.

The length of the prism is given as 12 meters.

Volume = area of base * length of prism = 36 square meters * 12 meters = 432 cubic meters.

Adjust for the shape of the prism.

Since the prism is a triangular prism, we need to divide the volume by 2.

Adjusted Volume = (1/2) * 432 cubic meters = 216 cubic meters.

Therefore, the volume of the triangular prism is 216 cubic meters.

We can draw about the president's approval rating, based on the given poll with an 8% margin of error, is that it falls within the range of 34.6% to 50.6%.

Given that the approval rating of the president is 42.6% and the margin of error is 8%, we can draw the following conclusions:

The approval rating falls within a range. The margin of error indicates that the actual approval rating could be 8% higher or 8% lower than the reported value of 42.6%.

Calculating the range:

The upper bound of the range: 42.6% + 8% = 50.6%

The lower bound of the range: 42.6% - 8% = 34.6%

Therefore, based on the poll with an 8% margin of error, we can conclude that the president's approval rating falls within the range of 34.6% to 50.6%.

It is important to note that the true approval rating of the president lies within this range with a certain level of confidence, typically associated with the confidence level of the poll.

The standard form for the linear equation is: y= -14a+63.

The standard form for the linear equation is: y= ax+b , for example, y=8x+3. Where:

a= the slope. It can be calculated for Δy/Δx .

b= the constant term that represents the y-intercept.

An equation can be represented by a linear function.

For the given example: a=7 and b=2.

For solving  linear equations, you should organize variables on one side of the equation and the numbers on the other side. When a number or variables change side, its signal also is changed.

The question gives:

For the point 1 (4,7), you can write:

y = ax + b

7 = a*4 + b

For the point 2 (5, -7), you can write:

y = ax + b

-7 = a*5 + b

Then, you have two equations:

7 = a*4 + b (1)

-7 = a*5 + b (2)

You have a system of equations, for solving it you should multiply the equation 2 by (-1) and after that sum the equations 1 and 2.

7 = a*4 + b (1)

7 = -a*5 - b (2)

The sum will be

14 = - a

a = -14

From equation 1, if a = -14,

7 = a*4 + b

7 = (-14)*4 +b

7 = -56 + b

b= 56+7

b = 63

The Wald test is a statistical test that can be used to test the significance of a group of coefficients in a multiple regression model.

The test statistic is calculated as the ratio of the estimated coefficient to its standard error. If the test statistic is significant, then the null hypothesis that the coefficient is equal to zero can be rejected.

Suppose we have a multiple regression model with three independent variables: age, gender, and education. We want to test the hypothesis that the coefficients for age and education are both equal to zero. The Wald test statistic would be calculated as follows:

Test statistic = (Estimated coefficient for age) / (Standard error of estimated coefficient for age) + (Estimated coefficient for education) / (Standard error of estimated coefficient for education)

If the test statistic is significant, then we can reject the null hypothesis that the coefficients for age and education are both equal to zero. This would mean that there is evidence that age and education are both associated with the dependent variable.

The Wald test is a powerful tool that can be used to test the significance of a group of coefficients in a multiple regression model. However, it is important to note that the test statistic is only valid if the assumptions of the multiple regression model are met. If the assumptions are not met, then the p-value of the Wald test may be inaccurate.

Here are some of the assumptions of the multiple regression model:

* The independent variables are independent of each other.

* The dependent variable is normally distributed.

* The errors are normally distributed.

* The errors have constant variance.

If any of these assumptions are not met, then the Wald test may not be accurate.

If we pay 12.5 percent for 10 years, our monthly payment for a $6000 loan will be about (C) $55.58.

In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100. Although "pct," "pct," and occasionally "pc" are also used as abbreviations, the percent symbol "%" is most usually used to denote it.

A % is a number that has neither dimensions nor a defined unit of measurement.

To calculate the percentage, we must divide the value by the entire amount and then multiply the result by 100.

So, if the interest rate is 12.5%, our total loan payment would be:

112.5/100 × 6,000 = $6,750.

The monthly payment would be if there was no buildup and other agreement in payment:

6750/12*10

Given:

\(\Delta PQR\cong \Delta XYZ\)

\(PQ=3a+4\)

\(XY=5a-12\)

To find:

The value of a and PQ.

Solution:

We have,

\(\Delta PQR\cong \Delta XYZ\)

\(PQ\cong XY\)                            (CPCTC)

So,

\(PQ=XY\)

\(3a+4=5a-12\)

Isolating variable terms, we get

\(3a-5a=-4-12\)

\(-2a=-16\)

Divide both sides by -2.

\(a=\dfrac{-16}{-2}\)

\(a=8\)

Now,

\(PQ=3a+4\)

\(PQ=3(8)+4\)

\(PQ=24+4\)

\(PQ=28\)

Therefore, the value of a is 8 and the value of PQ is 28.

To find the lengths of the sides of the triangle with vertices at a(0, -4), b(0, -9), and c(-2, -5), we can use the distance formula:

Distance = √((x2 - x1)² + (y2 - y1)²)

Let's label the sides of the triangle as AB, BC, and CA, where A = (0, -4), B = (0, -9), and C = (-2, -5).

Length of AB:

AB = √((y2 - y1)² + (x2 - x1)²) (Note: We switched the order of x and y for this calculation to match the order of the points given)

= √((-9 - (-4))² + (0 - 0)²)

= √(5²)

= 5

Length of BC:

BC = √((y2 - y1)² + (x2 - x1)²)

= √((-5 - (-9))² + (-2 - 0)²)

= √(4² + 4²)

= √32

= 4√2

= 5.66

Length of CA:

CA = √((y2 - y1)² + (x2 - x1)²)

= √((-4 - (-5))² + (0 - (-2))²)

= √(1² + 2²)

= √5

= 2.24

Therefore, the lengths of the sides of the triangle areAB = 5

BC = 4√2 ≈ 5.66

CA = √5 ≈ 2.24

Since they are unequal, the triangle is a scalene triangle.

2)
To determine if AABC is a right-angled triangle, we need to check if any of its angles measure 90 degrees. We can use the slopes of the sides to determine this.

The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:

slope = (y2 - y1) / (x2 - x1)

Using this formula, we can calculate the slopes of the three sides of AABC:

Slope of AB:

AB passes through the points A(0, -4) and B(0, -9).

slope_AB = (-9 - (-4)) / (0 - 0) = -5/0 (undefined)

Note that the slope of AB is undefined, since the line is vertical and has no defined slope.

Slope of BC:

BC passes through the points B(0, -9) and C(-2, -5).

slope_BC = (-5 - (-9)) / (-2 - 0) = 2

Slope of CA:

CA passes through the points C(-2, -5) and A(0, -4).

slope_CA = (-4 - (-5)) / (0 - (-2)) = 1/2

Since AB is vertical and has undefined slope, we cannot use its slope to determine the angle at A. However, we can use the slopes of BC and CA to check the other angles.

The angle at B is opposite the side BC, so we need to check if the slope of BC is the negative reciprocal of the slope of AB. Since AB has undefined slope, we cannot determine its reciprocal or negative reciprocal. Therefore, we cannot use this method to check if the angle at B is 90 degrees.

The angle at C is opposite the side CA, so we need to check if the slope of CA is the negative reciprocal of the slope of BC. If it is, then the angle at C is 90 degrees. Let's check:

slope_BC * slope_CA = 2 * 1/2 = 1

The negative reciprocal of slope_BC is -1/2.

Since slope_CA is not equal to the negative reciprocal of slope_BC, we can conclude that the angle at C is not 90 degrees.

Therefore, we CANNOT conclude that AABC is a right-angled triangle based on the slopes of its sides.

To calculate the heart rate from an ECG recorded on millimeter grid paper, you can use the following formula:

Heart rate (beats per minute) = (recording speed (mm/s) / distance between cycles (mm)) x 60 s/min

Using the given information, the calculation would be:

Heart rate (beats per minute) = (25 mm/s / 15 mm) x 60 s/min = 100 beats per minute

Therefore, the subject's heart rate is 100 beats per minute.
