Answer:

13/102

Step-by-step explanation:

There are 52 cards in a standard deck (not including the jokers).

So let's start with the first thing... the red part. Half the deck is red which means 52/2=26 cards are red.

So the probability of the red being drawn is 26/52 (I'm going to keep it an un-reduced form for now)

So now since it says we don't replace (we don't put the card back into the deck), there is only 51 cards to choose from now.  There are 4 suits so there are 13 of each kind of suit. So to draw a spade, the probability would be 13/51.

So the end: The probability of drawing a red then a spade without replacing is the multiplication of these probabilities I found:

So the answer is 26/52  * 13/51=13/102

Undefined terms such as points and lines are central to defining geometric concepts such as line segments and angles. They also play a crucial role in the Cartesian coordinate system, where points are defined in relation to lines (axes).

In Mathematics, particularly in Geometry, the undefined terms points and lines are used to define several other concepts. One such concept defined by these undefined terms is the 'Line Segment'. A Line Segment is simply part of a line that is bounded by two distinct endpoints, and contains every point on the line between its endpoints. Both points and lines have a defining role in constructing this definition. A line segment is an example of 'one-dimensional' structure, as it only extends in one direction, unlike a plane or volume that extend in two or three dimensions, respectively.

Another major concept that is defined using points and lines is the 'Angle'. An angle is formed when two lines meet at a point. The point is called the vertex of the angle, and the lines are the sides of the angle.

In the Cartesian coordinate system, the interaction of points and lines is at the core of defining and plotting positions. For example, a point in this system is represented by two coordinates (x, y) - where x represents its position along the x-axis (a horizontal line) and y represents its position along the y-axis (a vertical line).

12.5 times larger is the storage capacity of Meredith's new hard drive

Step-by-step explanation:

Meredith's new computer storage capacity = 1.5 x 10^12

Meredith's old computer storage capacity = 1.2 X 10^11

times the storage capacity of Meredith's new hard drive is larger = Meredith's new computer storage capacity/Meredith's old computer storage capacity

= 1.5X10^12/1.2X10^11

= 12.5

So, 12.5 times larger is the storage capacity of Meredith's new hard drive

Answer:

Step-by-step explanation:

Givens

To find how many times larger is the new hard drive thatn the old one, we just need to divide

[tex]\frac{1.5 \times 10^{12}bytes }{1.2 \times 10^{11} bytes }=1.25 \times 10 = 12.5[/tex]

Therefore, the new hard driave can store 12.5 times more than the old hard drive.

Answer:

no

Step-by-step explanation:

to know if a number is divisible by 4, you need to look only at the last two digits and see if that is divisible, 15 is not divisible by 4 and therefore the whole number isnt.

if you tried to divided 262,015 by 4 you would get 65503.75, a decimial so not divisible

Answer:

No, 262,015 will not divide evenly into 4.

Step-by-step explanation:

262,015 ÷ 4 = 65503.75.

Therefore, it will not divide evenly into 4.

Another way to do this is to check if the last two digits are divisible by 4.

The last two digits are 15. 15 is not divisible by 4. Therefore, the entire number will not be divisible by 4.

Answer:

[tex]x<-2\\\\y\leq-x-2[/tex]

Step-by-step explanation:

From the given graph , the shaded region is bounded by two lines ( one is dotted and another is solid line).

Dotted line :  It is parallel to y-axis and intersecting the x -axis at .

so the equation of the line is x=-2.

But it is represented in dotted form it means the inequality sign used here is strictly less than.

i.e. the equation for dotted line = [tex]x<-2[/tex]

Solid line : It is passing through (-2,0) and (-1,-1).

Equation of line passing through (a,b) and (c,d) :-

[tex](y-a)=\dfrac{d-b}{c-a}(x-b)[/tex]

Then equation of sold line:

[tex](y-0)=\dfrac{-1-0}{-1-(-2)}(x-(-2))\\\\\Rightarrow\ y=\dfrac{-1}{-1+2}(x+2)\\\\\Rightarrow\ y=\dfrac{-1}{1}(x+2)\\\\\Rightarrow\ y=-x-2[/tex]

Hence, the inequality represents solid line(≤)= [tex]y\leq-x-2[/tex]

Hence, the system of linear inequalities is graphed will be :-

[tex]9+\frac{n}{5} =19[/tex]

[tex]\frac{n}{5} =19-9[/tex]

[tex]19-9=10[/tex]

[tex]\frac{n}{5} =10[/tex]

[tex]5\times10=50[/tex]

[tex]n=50[/tex]

[tex]\textbf{$\left[\begin{array}{cc}x & y\\-3 & 12\\-6 & 24\\-9 & 36\end{array}\right]$}[/tex]

Two variables have a proportional relationship if the ratios are equivalent. In other words, in this type of cases two quantities vary directly with each other, so we can write this in a mathematical language as follows:

[tex]y=kx[/tex]

Here [tex]k[/tex] is the slope of the linear equation defined above. So, verifying that k is constant we have:

[tex]k=\frac{24-12}{-6-(-3))}=\frac{36-24}{-9-(-6)}=\frac{36-12}{-9-(-3)}=-4 \\ \\ \therefore \boxed{k=-4}[/tex]

One way to prove this is by writing the equation that represents the table. From the two-point intercept form of the equation of a line we have:

[tex]y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1}) \\ \\ P(x_{1},y_{1})=P(-3,12) \\ \\ P(x_{2},y_{2})=P(-6,24) \\ \\ Subtituting \ x_{1}, x_{2}, y_{1}, y_{2}: \\ \\ y-12=\frac{24-12}{-6-(-3)}(x-(-3)) \\ \\ y-12=-4(x+3) \\ \\ Solving: \\ \\ y-12=-4x-12 \\ \\ Adding \ 12 \ to \ both \ sides: \\ \\ y-12+12=-4x-12+12 \\ \\ \boxed{y=-4x}[/tex]

So, this implies that the ordered pairs of the last option represent a proportional relationship

Answer:

Step-by-step explanation:

In this case, an proportional realtionship refer to the existence of a contant ratio of change between variables, that is, each y-value can be found by multiplying each x-value with this constant ratio of change.

So, notice that in the first table, is we multiply by four, you can get the first two pairs, but the last one doesn't fall into the ratio. That's not the answer.

Similarly, the second table doesn't have a constant ratio of change, because the last pair has different ratio.

However, the last table shows a constant ratio of change, because each x-value can be multiplied by -4, to get each y-value, that is

-3 x -4 = 12

-6 x -4 = 24

-9 x -4 = 36

Therefore, the right answer is the last table.

Answer:

y = [tex]\frac{3}{2}[/tex] x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x - 2y = - 6 into this form

Subtract 3x from both sides

- 2y = - 3x - 6 ( divide all terms by - 2 )

y = [tex]\frac{3}{2}[/tex] x + 3 ← in slope- intercept form

with slope m = [tex]\frac{3}{2}[/tex]

• Parallel lines have equal slopes, hence

y = [tex]\frac{3}{2}[/tex] x + c ← partial equation of parallel line

To find c substitute (4, 2) into the partial equation

2 = 6 + c ⇒ c = 2 - 6 = - 4

y = [tex]\frac{3}{2}[/tex] x - 4 ← equation of parallel line

Answer:

308.65 Pounds

Step-by-step explanation:

Since one kilogram is 2.20462 pounds you can multiply 140 by 2.20462 to get 308.6468 and rounded to the nearest hundredth it would be 308.65.

The weight of a 140 kilogram person in pounds is approximately 308.64 pounds, when rounded to the nearest hundredth.

To find the weight of a 140-kilogram person in pounds, we first need to understand that weight is a measure of the force of gravity on an object and can be calculated by multiplying the mass of the object by the acceleration due to gravity.

However, here, we are converting kilograms to pounds, which is a conversion of mass units, not weight. The conversion factor from kilograms to pounds is approximately 2.2046.

Therefore, to convert 140 kilograms into pounds, we multiply 140 by 2.2046:

140 kg * 2.2046 = 308.644 pounds.

And rounded to the nearest hundredth, we get 308.64 pounds.

The closing bracket ']' in the inequality solution set (–∞, 6.5] indicates that 6.5 is included, making it a solution to the inequality.

The solution to an inequality is (–∞, 6.5]. To determine if 6.5 is a solution to the inequality, we look at the notation used. The parenthesis '(' indicates that the number at this end of the interval is not included in the solution set, while the bracket ']' indicates that the number at this end is included. Since 6.5 is associated with a closing bracket, it means that 6.5 is indeed a solution to the inequality. Therefore, any number less than or equal to 6.5 is a solution to this particular inequality.

The correct explanation among the given options is the following:

"The solution includes numbers from negative infinity to 6.5. Because a bracket is used, the solution includes 6.5."

In interval notation, brackets ([ and ]) indicate that the endpoint is included in the solution, while parentheses (( and )) indicate that the endpoint is not included.

Here, with (-∞, 6.5], the closing bracket means 6.5 is included in the solution to the inequality.

Thus, 6.5 is a valid solution to the inequality.

The complete question is : The solution to an inequality is (-, 6.5]. Is 6.5 a solution to the inequality? Explain your answer

The solution includes numbers from negative infinity to 6.5. Because a bracket is used, the salution does not

include 6.5. The solution includes numbers from 6.5 to infinity. Because a parenthesis is used, the solution does not include 6.5.

The solution is the point(, 6.5). Because a bracket is used, 6.5 is a solution to the inequality.

The solution includes numbers from negative infinity to 6.5. Because a bracket is used, the solution includes 6.5.
