[tex]|\Omega|=6^2=36\\|A|=1\cdot5\cdot2+1=11\\\\P(A)=\dfrac{11}{36}\approx30.6\%[/tex]

Answer:

[tex]P=\frac{13}{36}=0.361[/tex]

Step-by-step explanation:

There are six possible outcomes when rolling a die. Therefore the probability of obtaining a 3 is a given is

[tex]P = \frac{1}{6}[/tex].

When throwing the two dice together, the probability of obtaining a 3 is the same:

[tex]P_1 = \frac{1}{6} * \frac{5}{6} + \frac{5}{6} * \frac{1}{6}=\frac{5}{18}[/tex]

Since the events are independent then the probability of obtaining a three in both dice is:

[tex]P_2 = \frac{1}{6} * \frac{1}{6} = \frac{1}{12}[/tex].

Finally the probability of obtaining a 3 on a given or both is equal to the sum of the probabilities [tex]P_1[/tex] and [tex]P_2[/tex]

[tex]P=\frac{1}{12}+\frac{5}{18}=\frac{13}{36}=0.361[/tex]

Answer:

x(t)=-t/4

y(t)=-t-2

(answer can vary)

Step-by-step explanation:

Many different ways to do... you are just introducing a different variable, t, to rewrite x and y.  We are rewriting x and y as functions of t.

So if we let -4x=t  then x=t/-4 or x=-t/4

So if -4x=t then t+y=-2 so y=-t-2

So you could write the following:

x(t)=-t/4

y(t)=-t-2

Answer: the answer is a)x=t,y=4t-2

Answer:

25 percent.

Step-by-step explanation:

1,000 would be 20% of 5,000

250 is 5% of 5,000

20+5=25

25% of Emma's monthly income goes towards rent.

To calculate the percentage of Emma's monthly pay that goes towards rent, we need to divide the amount spent on rent by the total monthly income, and then multiply that result by 100 to convert it to a percentage.

Emma spends $1,250 a month on rent and earns $5,000 per month. The calculation is as follows:

Divide the monthly rent by the monthly income: $1,250 / $5,000 = 0.25.

Convert the decimal to a percentage: 0.25 * 100 = 25%.

Therefore, 25% of Emma's monthly income goes towards rent.

Answer:

See explanation. (Also you can write an equation several different ways so without the choices I cannot tell you which)

Step-by-step explanation:

Slope-intercept form is y=mx+b

So one way to write the equation is y=-3/4 x +3/2

There are more ways to write it.

Every line about to write is a way to write it.

Multiply both sides by 4:                 4y=-3x+6

Add 3x on both sides:               3x+4y=6

Subtract 6 on both sides:         3x+4y-6=0

There are a lot of ways to write an equation like this.

Answer:

y=-2/5 x -1 (It says check all that apply... I hope this equation hasn't been written in a different form in your choices-let me know)

Step-by-step explanation:

Rearrange 2x+5y=10 into slope-intercept form.

First step: Subtract 2x on both sides:  5y=-2x+10

Second step: Divide both sides by 5 giving: y=-2/5 x+2

The slope is -2/5.

Parallel lines have the same slope.

So we know the equation of our new line is in the form y=-2/5 x+b.

We need to find the y-intercept of our line... let's just use the point they have our line going through to find it. Plug in and solve for b.

1=-2/5 (-5)+b

1=2+b

-1=b

So the equation is y=-2/5 x -1

Answer:

see explanation

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 2x + 5y = 10 into this form

Subtract 2x from both sides

5y = - 2x + 10 ( divide all terms by 5 )

y = - [tex]\frac{2}{5}[/tex] x + 2 ← in slope- intercept form

with slope m = - [tex]\frac{2}{5}[/tex]

• Parallel lines have equal slopes, so

y = - [tex]\frac{2}{5}[/tex] x + c ← is the partial equation of the parallel line

To find c substitute (- 5, 1) into the partial equation

1 = 2 + c ⇒ c = 1 - 2 = - 1

y = - [tex]\frac{2}{5}[/tex] x - 1 ← in slope- intercept form

Multiply through by 5

5y = - 2x - 5 ( add 2x to both sides )

2x + 5y = - 5 ← in standard form

Part 1) The ratio of the areas of triangle TOS to triangle TQR is [tex]\frac{4}{25}[/tex]

Part 2) The ratio of the areas of triangle TOS to triangle QOP is [tex]\frac{4}{9}[/tex]

Step-by-step explanation:

Part 1) Find the ratio of the areas of triangle TOS to triangle TQR

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

The scale factor is equal to

TS/TR

substitute the values

6/(6+9)

6/15=2/5

step 2

Find the ratio of the areas of triangle TOS to triangle TQR

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

so

[tex](\frac{2}{5})^{2}=\frac{4}{25}[/tex]

Part 2) Find the ratio of the areas of triangle TOS to triangle QOP

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

The scale factor is equal to

TS/QP

substitute the values

6/9

6/9=2/3

step 2

Find the ratio of the areas of triangle TOS to triangle QOP

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

so

[tex](\frac{2}{3})^{2}=\frac{4}{9}[/tex]

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The slope of a line perpendicular to 3x + y =15 is 1/3. Thus, the correct option is C.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

In the given equation 3x + y =15, the slope of the line will be,

3x + y = 15

y = 15 - 3x

y = -3x + 15

Thus, the slope of the equation is -3.

Now, the product of the slope of two perpendicular lines is always equal to -1. Therefore, the product can be written as,

-3 × m = -1

m = -1/-3

m = 1/3

Hence, the slope of a line perpendicular to 3x + y =15 is 1/3. Thus, the correct option is C.

Answer:

Another point is (3,1) and the vertex is (0,0)

Step-by-step explanation:

The vertex is still (0,0) since the parabola has only been stretched some way and not shifted from the parent function f(x)=x^2.

Enter in any x you like like 3 (I chose 3 because I see I'm going to multiply by 1/3). Anyways

g(3)=(1/3*3)^2=(1)^2=1  so another point on the parabola is (3,1)... Now just use the fact that all parabolas are symmetrical to graph it.

Answer: A. It would be shifted up.

Step-by-step explanation: the only thing that is changing in the two equations is the last number. The last number is not there in the second equation because the y-intercept is 0. The y-intercept in the first equation is -2 and shifts up 2 to y-intercept if 0. Therefore, your answer would be A. It would shift up.

The graph of the new equation compared with the original graph is the new graph would be shifted up.

Option A is the correct answer.

We have,

If the equation y = 12x - 2 were changed to y = 12x, the graph of the new function would be different from the original.

The original equation y = 12x - 2 represents a linear function with a slope of 12 and a y-intercept of -2.

The graph of this equation would be a straight line that is steep (with a slope of 12) and shifted downward by 2 units (due to the y-intercept of -2).

However, if we change the equation to y = 12x, the new equation represents a linear function with the same slope of 12 but with no y-intercept (it passes through the origin).

The graph of this equation would still be a straight line, but it would be shifted up compared to the original equation since the y-intercept has been removed.

Therefore,

It would be shifted up.

The solution to the given system of equations is (8, -22). Therefore, option C is the correct answer.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

From the table 1.

Slope (m) = (18-26)/(-2-(-4))

= -8/2

m=-4

Substitute m=-4 and (x, y)=(-2, 18) in y=mx+c, we get

18=-4(-2)+c

18=8+c

c=10

So, the equation is y=-4x+10 -----(i)

From table 2:

Slope (m)=(8-14)(-2-(-4))

m=-3

Substitute m=-3 and (x, y)=(-2, 8) in y=mx+c, we get

8=-3(-2)+c

c=2

So, the equation is y=-3x+2 --------(ii)

From equation (i) and (ii), we get

-4x+10 =-3x+2

x=8

Substitute x=8 in equation (i), we get

y=-4(8)+10

y=-22

So, the solution is (8, -22)

Final answer:

Without a specific definition of ƒ(x), we can't provide a precise evaluation at x = 10. However, if ƒ(x) is a constant function such as ƒ(x) = 20 for the range of 0 to 20, then ƒ(10) would be 20.

Explanation:

To evaluate the function ƒ(x) when x = 10, we need to know the specific form of the function. However, based on the information provided, which seems fragmented and from different contexts, I can assume that ƒ(x) is defined for certain ranges. There’s reference to a horizontal line graph representation of a function, which suggests that ƒ(x) could potentially be a constant function within a certain range. If the function ƒ(x) is indeed a constant function, such as ƒ(x) = 20 for 0 ≤ x ≤ 20, then evaluating it at x = 10 would simply give the constant value, which is 20.

From the other contexts provided, it's implied that there could be scenarios where ƒ(x) represents different mathematical or physics concepts, such as force, probability distribution, or equations of motion. Without a direct specification of ƒ(x) for the x value in question, the remaining information cannot be used to definitively evaluate ƒ(x) at x = 10.

Step-by-step explanation:

This is a problem related to ratio and proportion. We are given the number of Green Grapes and the ration of Green Grapes to the Black Grapes

The ratio is 3:4

This means

[tex]\frac{G_g}{G_b} = \frac{3}{4}[/tex]

Now assume that the number of Black Grapes = x

Given that [tex]G_g[/tex]=24

Substituting these values in [tex]\frac{G_g}{G_b} = \frac{3}{4}[/tex]

[tex]\frac{24}{x} = \frac{3}{4}[/tex]

[tex]24*4 = 3*x\\x=\frac{24*4}{3}\\x=\frac{8*4}{1}\\x=32[/tex]

Hence the number of Black Grapes are 32

Answer:
