The required scale factor for the dialed triangle is given by SF= 6.28

A triangle with vertices at A(0,0), B(0,4), and C(6,0) is dilated to yield a triangle with vertices at A(0,0), (B(0,10), and C (C(15,0).

The scale factor is defined as the ratio of modified change in length to the original length.

Since, the height and base of the triangle is y coordinate of B and x coordinate of c is given by 4, 6
Area of triangle =1/2(base x height)
                         = 1/2 (4 x 6)
                         =   4.8
Similarly, for dilated triangle
Area of dilated triangle =  30

Now, scale factor(SF) = area of dilated triangle \ area of triangle
SF = 30/4.8
SF = 6.25

Thus, the required scale factor is SF = 6.25

The correct option is A.

domain: x > -2; range: all real numbers

Here we have a logarithmic function.

Remember that the argument of a logarithm must be larger than zero, in this case the argument is:

x + 2

So we must have:

x + 2 > 0

x > -2

Then the domain is:  x > -2.

And the range of any logarithmic function is the set of all real numbers.

Answer:

C. About 50 percent is soccer, 25 percent is baseball, 25 percent is basketball.

Step-by-step explanation:

400 students at a sports camp.

200 play soccer, which is 50% or half of the students at the sports camp.

100 play baseball, which is 25% or a quarter of the students at the camp.

100 play basketball, which is also 25% or a quarter of the students at the camp.

So, the circle graph that shows soccer 50%, baseball 25%, and basketball 25%, is the answer.

Step-by-step explanation:

So two equations have infinitely many solutions, when they are exactly the same equation, in their most simplified form, for example: 2x = 3x-x which simplifies to 2x=2x. So in the options, three of the options have the same equation on the right side, so I'll distribute the 5. [tex]5(y+3) = 5y+15[/tex]. Now let's look at the options:

Option D: The measure of angle BCA = The measure of angle C prime A prime B prime

We are told that Triangle ABC is transformed to triangle A′B′C′.

Now,  the triangle ABC and A'B'C' are similar triangles and we know that similar triangles angles are congruent. Thus;

From the given coordinates, we can say that;

∠BAC = ∠B'A'C'

∠ABC = ∠A'B'C'

∠ACB = ∠A'C'B'

The new amount of neon gas when the temperature drops is 2.30L.

Charles's law

Charles's law states, "The volume occupied by a particular amount of gas is directly proportional to its absolute temperature.

Initial temperature of gas T₁ = 50 ° C = 323.15K

Initial volume of gas V₁ = 2.5L

Final temperature T₂ = 25 ° C = 298.15K

Final capacity V₂ =? Neon gas, substitute the given value into the above equation:

V₁ / T₁ = V₂ / T₂

V₂ = V₁T₂ / T₁

V₂ = (2.5L × 298.15K) ) / 323.15K

V₂ = 2.30 l

Therefore, the new volume when the temperature of the neon gas drops is 2.30l.

Answer:

7.5 cm

Step-by-step explanation:

The perimeter of a rectangle is the sum of the length of all its sides.

Perimeter of rectangle= 2(length +breadth)

Given: perimeter= 24 cm, breadth= 4.5 cm

Substitute the given information into the formula:

24= 2(length +4.5)

Divide both sides by 2:

length +4.5= 12

Subtract 4.5 from both sides:

length

= 12 -4.5

= 7.5

Thus, the rectangle is 7.5 cm long.

Answer:

Step-by-step explanation:

Multicollinearity is used to describe the problem of using variables that strongly correlate with one another in a multiple linear regression model.

Multiple linear regression refers to a statistical technique that is used to predict the outcome of a variable based on the value of two or more variables. It is sometimes known simply as multiple regression, and it is an extension of linear regression. The variable that we want to predict is known as the dependent variable, while the variables we use to predict the value of the dependent variable are known as independent or explanatory variables.

Multicollinearity, also known as collinearity, is a phenomena in statistics when one predictor variable in a multiple regression model can be linearly predicted from the others with a high level of accuracy. In this case, minor adjustments to the model or the data may cause the multiple regression's coefficient estimates to fluctuate unpredictably. Multicollinearity only impacts calculations pertaining to specific predictors; it has no impact on the predictive capability or reliability of the model as a whole, at least within the sample data set. In other words, a multivariate regression model with collinear predictors can show how well the entire set of predictors predicts the outcome variable, but it might not provide accurate information about any particular predictor or about which predictors are redundant with respect to another predictor.

When Area of rectangle is constant, then the length x is inversely proportional to the width y of the rectangle.

[tex]x\propto \frac{1}{y} [/tex]

We know that the area of a rectangle is given by the product of the length and width of the rectangle.

Area = Length*Width

In this given problem,

The length of the rerectanglctangle is represented by x

and the width of the rectangle is represented by y

If the area of the rectangle is represented by A now.

So by the formula,

A = x*y

When A is constant then,

x = A/y

[tex]\therefore x \propto \frac{1}{y}[/tex]

So from the above calculation we can conclude that about relation between length and width that,

A two-way table is a way to display frequencies or relative frequencies for two variables.

One of the variables is represented using rows and the other one using columns.

They are used to see if there is any relationship between the two variables.

Given that, the ages and grades of some of the 19 girls on a club soccer team are shown in the given table.

We need to select the table showing the correct marginal frequencies.

So, we see that,  

Table A and Table D add up to a total of 21 girls.

The question says there are 19 girls, so those two are eliminated.

Table B's data doesn't even add properly so that is eliminated too.
