Your sock drawer has two white socks, four brown socks, and two black socks. You randomly pick a sock and put it on your left foot and then pick another sock and put it on your right foot. You leave the house with a white sock on your left foot and a brown sock on your right foot. Find the probability of this occuring.

Answers

Answer:

1/7

Step-by-step explanation:

From the above question, we have the following values:

White socks = 2

Brown socks = 4

Black socks = 2

Total number of socks = 8

We are told in the question that:

You randomly pick a sock and put it on your left foot and then pick another sock and put it on your right foot. You leave the house with a white sock on your left foot and a brown sock on your right foot.

From above question, we can see that this is a probability with dependent events. This means have a white sock on your left foot and brown sock on your right are events that depend on each other, hence, the probability will occur with replacement.

The probability ( having a white sock on your left foot and brown sock on right) =

2/8 × 4/7

= 8/56

= 1/7

Therefore, the probability of this occuring is 1/7

$185.45 $205.20 $195.05 $245.80 $262.00

Answers

Answer:

$218.70

Step-by-step explanation:

You need to first convert the percentage to the decimal.

20% = 0.2

Now, you need to find 20% of each bill by multiplying each bill by 0.2.

0.2(185.45) + 0.2(205.20) + 0.2(195.05) + 0.2(245.80) + 0.2(262.00)

Because of the distributive property, you can add up the bills and multiply the sum by 0.2.

0.2(185.45 + 205.20 + 195.05 + 245.80 + 262.00)

0.2(1093.50)

What is the slope of the line that passes through the points (10, 3)(10,3) and (2, 3) ?(2,3)? Write your answer in simplest form.

Answers

Answer:

0

Step-by-step explanation:

The y's are the same so they do not go up or down so the slope is 0.

The slope of the line passes through points (10, 3) and (2, 3) is 0.

Given that,
The slope of the line that passes through points (10, 3) and (2,3) is to be determined.

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

here,
The slope of the line passes through the point (10, 3) and (2, 3).
Now, put the point in the equation of the slope,

m =(y₂ - y₁) /  (x₂ - x₁)
m = 3 - 3 / (2 - 10)
m = 0 / -8
m = 0

Thus, the slope of the line passes through the points (10, 3) and (2, 3) is 0.

Averiguar el valor de los ángulos a. ¿Cuál es el complemento de un ángulo a=39º? b. Se sabe la amplitud del ángulo R=143º pero se desconoce la del ángulo m, ¿Cuánto medirá m?

Answers

Answer:

A y C  → complementarios

A Y B → suplementarios

D Y E  → suplementarios

El complemento de un ángulo de 39°, mide  51°

La amplitud de m, como suplemento es de 36°

Si lo tomamos como ángulo conjugado, es de 217°

Step-by-step explanation:

Ángulos completarios → Aquellos que sumados, me dan 90°

Ángulos complementarios → Aquellos que sumados, me dan 180°

Angulos complementarios entonces, son:

A y C (sumados, dan 90° → 25 + 65)

Angulos suplementarios entonces, son:

A y B (sumados, dan 180° → 25 + 155)

D y E (sumados, dan 180° → 30 + 150)

Complemento de un ángulo de 39° → Ya vimos que su suma debe dar 90°, por lo que el complemento mide: 90 - 39 = 51°

Si la amplitud del ángulo R es 143°, la del ángulo m, será 37°. Sería el ángulo suplementario a R.

No podríamos tener un complemento porque estamos en valores a 90°, pero también se podría obtener otro ángulo cuya amplitud sea de 217°, en este caso ambos ángulos suman 360°, se los llama angulos conjugados.

Problem: What values of a and b make this statement false? |a-b|=|a|-|b|

Answers

Answer:

All (a,b) that satisfy a.b < 0 will make that statement false

Step-by-step explanation:

It is only right when:

|a-b| = |a| - |b|

<=> ( |a-b| ) ^ 2 = ( |a| - |b| ) ^ 2

<=> a^2 - 2ab + b^2 = a^2 - 2.|ab| + b^2

<=> ab = |ab|

<=> ab ≥ 0

So, when ab < 0, it's wrong

A coordinate axis is drawn with a parabola pointing up that has vertex of 0,3. Determine the intervals on which the function is increasing, decreasing, and constant. Increasing x < 0; Decreasing x > 0 Increasing x > 0; Decreasing x < 0 Increasing x < 3; Decreasing x > 3 Increasing x > 3; Decreasing x < 3

Answers

Answer:

Option (2). Increasing x > 0; decreasing x < 0

Step-by-step explanation:

Equation of the parabola having vertex (0, 3) will be,

y = (x - 0)² + 3

y = x² + 3

To check the function is increasing or decreasing in the given intervals we will find the derivative of the function,

[tex]\frac{dy}{dx}=\frac{d}{dx}(x^{2}+3)[/tex]

y' = 2x

For x < 0 Or x = -1

y' = 2(-1)

  = -2 < 0

Therefore, function is decreasing in x < 0

For x > 0 Or x = 1

y' = 2(1) + 3

  = 5 > 0

Therefore, function is increasing in x > 0

Option (2) is the answer.

How to get the answer

Answers

Answer:

2*x^4*z^3

Step-by-step explanation:

To answer this kind of question, you first start rearranging the terms in the numerator and denominator, so you don't get confused.

3x^3 * 4x^3 * z^4 / 2x * x * 3z

Now you multiply like parts in the numerator and denominator to keep it simple.

(3x^3 * 4x^3) * z^4 / (2x * x) * 3z

3x^3 * 4x^3 = 12x^6

2x * x = 2x^2

12x^6 * z^4 / 2x^2 * 3z

Now divide like terms that are in the numerator and denominator so multiplying later will be easier.

12x^6 / 2x ^ 2 * z^4 / 3z

12x^6 / 2x^2 = 6x^4

z^4/3z = z^3 / 3

Now you multiply both terms,

6x^4 * z^3/3

2*x^4*z^3

How can you tell from the graph of Molly’s garden on the previous slide that it represents a proportional relationship?

Answers

Answer:

The graph of a proportional relationship has the same unit rate, is a straight line, and starts at the origin.

Step-by-step explanation:

this the answer

The graph of a proportional relationship is a straight line.

What is the equation of a straight line? What do you mean by domain and range of a linear function?

The general equation of a straight line is -

y = mx + c

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

Other possible equations of lines are -

(y - y₁) = m(x - x₁)                               {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁)    {Two point - slope form}x/a + y/b = 1                                      {intercept form}x cos(β) + y sin(β) = L                       {Normal form}

For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which [y] exists.

We have a graph of Molly’s garden.

Since, the graph is not given, i will write the condition for proportional relationship. The graph of a proportional relationship is a straight line whose equation is given by -

y = mx + c

Therefore, the graph of a proportional relationship is a straight line.

On three science tests, Olivia has received scores of 89%, 98%, and 96%. What is the lowest score Olivia can get on her fourth and final science test to
achieve an average score of 95%?

Answers

Answer:

97%

Step-by-step explanation:

89%+98%+96%+?=95×4

283+?=380

?=380-283

?=97%

The lowest score Olivia can get on her fourth test is 97%.

The average score can be determined by dividing the sum of the four scores by the total number of tests taken.

The first step is to determine the sum of the three scores Olivia already has.

Sum of scores = 89 + 98 + 96 = 283%

The second step is to multiply 95 x 4. 95% x 4 = 380%

The third step is to subtract 283% by 380%. 380% - 283% = 97%

Enter the measure of ZC.

Answers

Answer:

59°

Step-by-step explanation:

From the question given, we obtained the following:

C + (3x + 16) = 180 (sum of angle on a straight line)

5x – 54 = 3x + 16 (Altanate angles are equal)

Next, we shall determine the value of x.

This can be obtained as follow:

5x – 54 = 3x + 16

Collect like terms

5x – 3x = 16 + 54

2x = 70

Divide both side by the coefficient of x i.e 2

x = 70/2

x = 35

Finally, we shall determine the value of C as shown below:

C + 3x + 16 = 180

But, x = 35

C + 3(35) + 16 = 180

C + 105 + 16 = 180

C + 121 = 180

Collect like terms

C = 180 – 121

C = 59°

Therefore, the value of C is 59°

Preview: 5 People fit comfortably in a 2 foot by 2 foot area. Use this value to estimate the size of a
crowd that is 4 feet deep on both sides of the street along a 1-mile section of a parade route.

Answers

Answer:

The estimate size of the crowd is 52800 people

Step-by-step explanation:

The given information are;

The number of people that fit comfortably in a 2 by 2 foot area = 5

Therefore, we have;

The area occupied by the 5 people = 2 × 2

The crowd ratio = 5/(2 × 2) = 5/4

The area occupied by the crowd = 4 feet deep, and 1 mile long on both sides of the street

By conversion factors, 1 mile = 5,280 feet

Therefore, the area occupied by the crowd = 4 × 5280 × 2 = 42240 ft²

The number of people in the crowd = Crowd ratio × The area occupied by the crowd

The number of people in the crowd = 5/4 × 42240 = 52800 people

Therefore, The estimated size of the crowd = 52800 people.
