The coefficient on the intercept would change if the dependent variable, birth weight, was in ounces instead of pounds. It would be equal to 0.00, rounded to two decimal places.

The intercept coefficient represents the value of the dependent variable when all independent variables are equal to zero. In this case, it would represent the birth weight when all predictors are equal to zero. Since birth weight is measured in ounces, the intercept coefficient would represent the weight of a newborn when all predictors are equal to zero, which is not a meaningful or practical value. Therefore, the intercept coefficient would be equal to 0.00.

This result is expected since changing the unit of measurement of the dependent variable does not change the relationship between the dependent variable and the independent variables, only the scale of the coefficients. The regression equation would still provide useful information about the relationship between birth weight and the predictors, but the coefficients would need to be interpreted differently.

The area of triangle EFG, to the nearest square inch, is approximately 1061 square inches.

To find the area of triangle EFG, we can use the formula:

\(Area = (1/2) \times base \times height\)

In this case, the base of the triangle is FG, and the height is the perpendicular distance from vertex E to side FG.

First, let's find the length of FG. We can use the law of cosines:

FG² = EF² + EG² - 2 * EF * EG * cos(∠F)

EF = 72 inches

EG = 34 inches

∠F = 21°

Plugging these values into the equation:

FG² = 72² + 34² - 2 * 72 * 34 * cos(21°)

Solving for FG, we get:

FG ≈ 83.02 inches

Next, we need to find the height. We can use the formula:

height = \(EF \times sin( \angle F)\)

Plugging in the values:

height = 72 * sin(21°)

height ≈ 25.52 inches

Now we can calculate the area:

\(Area = (1/2) \times FG \times height\\Area = (1/2)\times 83.02 \times 25.52\)

Area ≈ 1060.78 square inches

The probability that you win at most once in the instant lottery when playing five times is approximately 0.4096.

To calculate the probability of winning at most once in the instant lottery when playing five times, we need to consider the different possibilities: winning zero times and winning once.

The probability of winning zero times (not winning) in one play is (1 - 0.2) = 0.8.

Since the outcomes are independent, the probability of winning zero times in five plays is (0.8)^5 = 0.32768.

The probability of winning once is given by the formula:

Probability of winning once = (number of ways to win once) * (probability of winning) * (probability of not winning the other times)

In this case, there is only one way to win once out of five plays, and the probability of winning is 0.2.

The probability of not winning the other four times is (1 - 0.2)^4 = 0.4096.

Therefore, the probability of winning once is 1 * 0.2 * 0.4096 = 0.08192.

To find the probability of winning at most once, we need to sum the probabilities of winning zero times and winning once:

Probability of winning at most once = Probability of winning zero times + Probability of winning once

= 0.32768 + 0.08192

= 0.4096

Therefore, the probability that you win at most once in the instant lottery when playing five times is approximately 0.4096.

Firstly we will form the equation using one time charge and the product of number of miles and charge per mile. Then we will keep the value in equation to find the total cost.

Forming the equation -

c = 31 + 0.13x

To find the final price of an item costing g dollars that is on sale for 15% off and charged 7% sales tax, you can use the following expressions:

Expression using two separate calculations:

Final price after discount = g - (0.15 × g)

Final price with sales tax = (1 + 0.07) × (Final price after discount)

Expression combining discount and sales tax:

Final price with discount and sales tax = (1 + 0.07) × (g - (0.15 × g))

Expression using a single calculation:

Final price = g × (1 - 0.15) × (1 + 0.07)

Step-by-step explanation:

Answer:

27/238 = n/100

Step-by-step explanation:

Let it be:

• x: The larger number.

• y: The smaller number.

Then, we can write the following system of equations:

To solve the system of equations, we can use the elimination method.

Step 1: Multiply by -3 the Equation 1.

Step 2: We add both equations.

Step 3: We solve the resultant equation.

Step 4: We replace the value of y in any of the initial equations. For example, in Equation 1. Then, we solve for x.

Therefore, the larger number is 16, and the smaller number is -14.

Initially the number is given by 48.

Let the tens digit be x.

Given that the unit digit is twice the tens digit.

So the unit digit will be = 2x.

So, the number will be = 10*x + 1*2x = 10x + 2x = 12x

When the digits are reversed then the unit digit become x and tens digit become 2x.

So the reversed number is = 10*2x + 1*x = 20x + x = 21x

According to question if the number is doubled, it will be 12 more than the number reversed. So the best suited equation for this is given by,

2*12x = 21x + 12

24x = 21x + 12

24x - 21x = 12

3x = 12

x = 12/3 = 4

So the number is = 12x = 12*4 = 48.

Hence the initial number is 48.

The value of X = 25.

Solution:

The two equations are

(i) the first condition is difference of x and y is 14

x - y = 14 ---------equation 1

(ii) the second condition of the given data is value of x is 3 times more than two times of y value.

x - 2y = 3 --------equation 2

From equation 2, we have to separate two variables x and y,

x = 3 + 2y  --------equation 3

We have to Substitute equation 3 in equation 1

3 + 2y - y = 14

3 + y = 14

y = 14 - 3

y = 11

Substitute y = 11 in equation 1........

x - 11 = 14

x = 14 + 11

Answer:

Step-by-step explanation:

Given the difference of x and y is 14, and the difference of x and 2y is 3, you want two equations, their graph, and the value of x.

The difference of 'a' and 'b' is (a -b). Here, the two differences are expressed as the equations ...

The attachment shows a graph of these equations. Their point of intersection is (25, 11), meaning the value of x is 25.

The graph of the first equation is easily drawn by recognizing the x- and y-intercepts are 14 and -14, respectively.

The graph of the second equation will go through the x-intercept point of (3, 0) and the y-intercept point of (0, -3/2). It is probably easier to graph this by hand by considering the x-intercept point and the slope of 1/2.

Since we're only interested in the value of x, it is convenient to eliminate the variable y. We can to that by subtracting the second equation from twice the first:

Using logarithmic differentiation to the derivative of y is dy/dx = ( X^2 +1)^3 (x – 1)^6 x^2 [3(2x)/(x^2 + 1) + 6/(x - 1) + 2/x]

Logarithmic differentiation is a technique used to find the derivative of a function by taking the natural logarithm of both sides. By applying this method to the given expression, we obtain the derivative dy/dx.

After expanding and simplifying the expression, the derivative is expressed as a product of the original function and a combination of terms involving x.

This approach allows us to differentiate complicated functions by taking advantage of the properties of logarithms. The final expression represents the derivative of the given function with respect to x.

Taking the natural logarithm of both sides, we get:

ln y = 3 ln (x^2 + 1) + 6 ln (x - 1) + 2 ln x

Now, differentiating both sides with respect to x:

1/y (dy/dx) = 3(2x)/(x^2 + 1) + 6/(x - 1) + 2/x

Multiplying both sides by y:

dy/dx = y [3(2x)/(x^2 + 1) + 6/(x - 1) + 2/x]

Substituting the expression for y:

dy/dx = ( X^2 +1)^3 (x – 1)^6 x^2 [3(2x)/(x^2 + 1) + 6/(x - 1) + 2/x]
