Answer:

A bill's chances are the same as Sandra's

Step-by-step explanation:

Bill's chances are the same as Sandra's chances.

To be lucky means to be favored by some unforeseen event. Thus, the fact that a person is lucky or not has no relation to the luck that another person may or may not have. That is, there is no link between the chances of one person and those of another, when they are in the same situation.

Therefore, neither Bill nor Sandra have a different chance of rolling doubles on the next roll of the dice.

Your answer is B. (3, 5/2)

Step-by-step explanation:

The formula to find the midpoint of a segment is

(x1 + x2) / 2 to find the x value

and (y1 + y2) / 2 to find the y value of the midpoint.

To find the midpoint of the segment in the photo, you would do...

-1 + 3 divided by 2, giving you 3 for your x

and then 2+3 divided by 2, giving you 5/2 for your y.

Hope this helps!

Answer:

B

Step-by-step explanation:

the midpoint is based on the average of the two pair of point X1 and X2 as Y1 and Y1 divided by 2, each one. So, if we settle X1 and Y1 as (-1,2) and X2 and Y1 as (7,3)

(X1 + X2)/2 = (-1+7)/2 = 6/2= 3

(Y1 + Y2)/2 = (2+3)/2 = 5/2

so, we get the Answer B (3 , 5/2)

Step-by-step explanation:

To horizontally stretch the linear parent function f(x) = x by a factor of 2, we replace 'x' in the original function with 'x/2'. Therefore, g(x) = x becomes g(x) = x/2 or g(x) = 1/2x.

When we talk about stretching the "linear parent function" f(x) = x horizontally by a factor of 2, we are essentially changing the 'x' values of the function, and the equation of the function changes accordingly. When a function is stretched horizontally by a factor of 'b', the new function becomes f(x/b). So, in this case, as the stretch factor is 2, the new function will be f(x/2).

This means that wherever you see 'x' in the original function, you replace it with 'x/2'. So, f(x) = x becomes g(x) = x/2. Therefore, the correct answer to your question is g(x) = 1/2x.

Answer:

A. [tex]\frac{1}{5} log_{3}x +log_{3}y[/tex]

Step-by-step explanation:

We have the expression

[tex]log_{3} (\sqrt[5]{x} *y)[/tex]

As these two values are being multiplied, we can separate the two and the sum of them will be equal to the multiplied version

[tex]log_{3}\sqrt[5]{x} +log_{3}y[/tex]

The [tex]\sqrt[5]{x}[/tex] can be rewritten as [tex]x^{\frac{1}{5} }[/tex]. This allows us to use the exponent rule. This means that it can be written as

[tex]\frac{1}{5} log_{3}x +log_{3}y[/tex]

Answer:

The second option, Denver received 21.3 inches of snow during the period from 1888 to 1889.

To know how many inches of snow did Denver receive, we need to sum each the number of inches received per year from 1888 to 1889.

So, from the graph, we have:

For Nov '88, 3 inches.

For Dec '88, 0.8 inches.

For Jan '89, 5.5 inches.

For Feb '89, 8.4 inches.

For Mar '89, 3.6 inches.

Now, adding the number of inches for each month/year, we have:

[tex]Total=3in+0.8in+5.5in+8.4in+3.6in=21.3inches[/tex]

Hence, we have that Denver received a total of 21.3 inches for the 1888-1889 year period.

An equation is an expression that shows the relationship between two or more variables and numbers.

The savings account can be represented by an arithmetic sequence in which the first term (a) = 8, and common difference (d) = 2. Hence, money saved after 12 weeks is:

[tex]S_{n}=\frac{n}{2}(2a+(n-1)d) \\\\S_{12}=\frac{12}{2}(2(8)+(12-1)2) = 228[/tex]

Answer:

y=6

Step-by-step explanation:

use elimination by making the ys opposite in value and eliminating them from the equation so there is only variable:

-3x+2y=6

2(4x-y=2)

-3x+2y=6

8x-2y=4

Combine like terms and divide by 5 on both sides.

5x=10

x=2

Plug x in to find y:

4(2)-y=2

8-y=2

y=6

The y-coordinate in the system of equations, we can use the elimination method. After manipulating the equations, we find that the y-coordinate of the solution is 6.

The y-coordinate of the solution for the given system of linear equations:

-3x + 2y = 6

4x - y = 2

We can use the method of substitution or elimination. Let's use elimination for this example:

Multiply the second equation by 2 to make the coefficients of y equal but opposite: -3x + 2y = 6 becomes -3x + 2y = 6 (unchanged) and 4x - y = 2 becomes 8x - 2y = 4.

Add the modified equations together: (-3x + 2y) + (8x - 2y) = 6 + 4, which simplifies to 5x = 10.

Divide by 5 to solve for x: x = 10 / 5, so x = 2.

Substitute x = 2 into one of the original equations to find y: -3(2) + 2y = 6, which simplifies to -6 + 2y = 6.

Add 6 to both sides to isolate 2y: 2y = 12.

Divide by 2 to solve for y: y = 12 / 2, so y = 6.

Therefore, the y-coordinate of the solution is 6.

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The probability of success (getting heads) on one roll DOESNT affect other rolls, so we need to find probability of getting a head in a roll.

Probability is defined as the number of favorable outcomes divided by the total number of outcomes.

Here, favorable outcome is getting a head. So, on one roll, getting a head is 1. Also, the total number of outcomes is either a head or a tail. So total number of outcomes is 2.

Thus,

P(Heads) = 1/2

The state with the second lowest population has the lowest population density.

The correct statement from the given option is The state with the second-lowest population has the lowest population density.

A ratio shows us the number of times a number contains another number.

The population density of a state is the ratio of the population of the state and the area of the state. Therefore, the population density of the states can be written as,

[tex]\text{Population density of state}=\dfrac{\text{Population of the state}}{\text{Area of the state}}\\\\\\\text{Population density of state A}=\dfrac{1,055,173}{2,677} = 394.163[/tex]

[tex]\text{Population density of state B}=\dfrac{1,333,089}{36,418} = 36.6\\\\\\\text{Population density of state C}=\dfrac{3,596,677}{5,543} = 648.87\\\\\\\text{Population density of state D}=\dfrac{6,745,408}{10,555} = 639.073[/tex]

Thus, the correct statement from the given option is The state with the second-lowest population has the lowest population density.

Final answer:

To find the probability that at least one of the investor's companies had outstanding prospects out of 400 newly formed companies, we can use the complement rule. The rounded probability is 0.0067747.

Explanation:

To find the probability that at least one of the investor's companies had outstanding prospects, we can use the complement rule. The complement of at least one company having outstanding prospects is that none of the companies have outstanding prospects. Since there are 400 companies in total and only 11 have outstanding prospects, the probability that a single company does not have outstanding prospects is 389/400. Therefore, the probability that both companies do not have outstanding prospects is (389/400)^2. The probability that at least one company has outstanding prospects is 1 - (389/400)^2.

Rounding this to seven decimal places, the probability that at least one of the investor's companies had outstanding prospects is 0.0067747.

C. An ellipse

Step-by-step explanation:

If you cut a cone on the side with an angle that will produce an ellipse-shaped plane.

if you were to cut the cone perpendicularly to its height (as if the double cone on the picture was straight up), you would get a circle as the plane, because it would be a transversal cut of a circular cone.

If you cut it with an angle, you're stretching the circle... so you'll have an ellipse.

It is NOT a parabola NOR a hyperbola, since both would require the cross-section to go through the base... which it does not in this problem.  Please refer to the image below.

(15−2x)(22−2x)x

Answer:

Volume of box = (15−2x)(22−2x)x

C is correct.

Step-by-step explanation:

A company is creating a box without a top from a piece of cardboard, but cutting out square corners with side length x.

The dimension of the cardboard must be 15 x 22 because all options has same value.

We have rectangle cardboard with 15 x 22. We cut square from each corner of the board with dimension x.

New length of box = 22 - 2x

New Width of box = 15 - 2x

Height of the box = x

Volume of box is equal to volume of cuboid.

Volume of box = LBH

                        = (15-2x)(22-2x)(x)

Hence, The correct volume of the box is (15-2x)(22-2x)(x)
