Answer:

[tex]P(A\cap B)=0.12[/tex]

Step-by-step explanation:

If two events, A and B are independent, then [tex]P(A\cap B)=P(A)\times P(B)[/tex], otherwise the two events are dependent.

If P(A)=0.60 and P(B) =0.20, then A and B are independent events, if

[tex]P(A\cap B)=0.60\times 0.20[/tex]

[tex]\implies P(A\cap B)=0.12[/tex]

Therefore the best complete is:

If P(A) = 0.60 and P(B) = 0.20, then A and B are independent events if [tex]P(A\cap B)=0.12[/tex]

Answer:

5.9

Step-by-step explanation:

The mean means arithmetic average (some people just say average here).

The average of 4 numbers is the sum of those 4 numbers divided by the number of numbers which is 4 in this case.

So we have this formula:

[tex]\frac{3.8+4.2+5.3+x}{4}=4.8[/tex]

Multiply both sides by 4:

[tex]3.8+4.2+5.3+x=4(4.8)[/tex]

Simplify:

[tex]13.3+x=19.2[/tex]

Subtract 13.3 on both sides:

[tex]x=19.2-13.3[/tex]

Simplify:

[tex]x=5.9[/tex]

Answer:

The person on top is wrong the answer is 14,400 in.² or D

Step-by-step explanation:

The correct option is B. 720in squared. The area of the rectangle, when enlarged by a factor of 6, scales by the square of 6, resulting in an enlarged area of 720 square inches.

To determine the area of a rectangle after it has been enlarged by a factor, we need to understand how area scales with respect to the linear dimensions. When a shape is enlarged by a factor, the area scales by the square of that factor.

Given:

→ Original area = 20 square inches

→ Enlargement factor = 6

Steps to Find the Enlarged Area:

→ Calculate the scaling factor for the area:

= 6²

= 36.

→ Multiply the original area by this scaling factor:

= 20 in² * 36

= 720 in².

Therefore, the area of the enlarged rectangle is 720 square inches, which corresponds to answer choice B.

Answer:

9.13 cm^2.

Step-by-step explanation:

The diagonal of the square = the diameter of the circle.

The length of the diagonal = 4√2 cm (because we have a 45-45-90 triangle), so the radius of the circle is half of this = 2√2 cm.

The area of the shaded part = area of the circle - area of the square

= π (2√2)^2 - 4^2

=  25.13 - 16

= 9.13 cm^2.

On a plotted graph, 'm' commonly represents the slope indicating how much the line rises or falls for each step across. On the other hand, 'n' usually demonstrates the y-intercept - the point where the line crosses the y-axis.

The relationship between the values of m and n plotted on a number line depends on the mathematic law or concept being applied. But in many cases, such as on a graph, 'm' typically represents the slope while the 'n' value shows the y-intercept.

Slope (m) shows how much a line moves up or down along the y-axis for each step across the x-axis ('run'). The equation for this is ∆y/∆x meaning the change in y over the change in x. For example, if the slope (m) is three, each time the x value increases by one, the y value will rise by three.

The y-intercept (n) is the point where the line crosses the y-axis. This is the value of y when x = 0.

Answer:

C. x + 9 = 11

Step-by-step explanation:

We are trying to identify which of the equations does not match with the others. In this case, solve for x in each equation:

Option A):

6 + x = 9

Subtract 6 from both sides:

6 (-6) + x = 9 (-6)

x = 9 - 6

x = 3

Option B):

15 = x + 12

Subtract 12 from both sides:

15 (-12) = x + 12 (-12)

15 - 12 =  x

x = 3

Option C):

x + 9 = 11

Subtract 9 from both sides:

x + 9 (-9) = 11 (-9)

x = 11 - 9

x = 2

Option D):

7 + x = 10

Subtract 7 from both sides:

x + 7 (-7) = 10 (-7)

x = 10 - 7

x = 3

A distance of 1 meter is 50 times 2 cm, so the actual distance between the two cities is 50 times 2.5 km, which is 125 km.

To find the actual distance between two cities on a map given a scale, convert the map distance to real-world distance using the scale ratio.

The actual distance between two cities on the map can be calculated as follows:

So, the actual distance between the two cities is 1.25 kilometers.

1 and 3 I believe are the correct answers

Answer:

Option 1 , Option 3 and Option 4 are correct.

Step-by-step explanation:

Number of customers using landlines decreases 10% per year.

Let x be the umber of customers using landlines in 2002.

⇒ Number of customer using landlines in 2003 = [tex]x-\frac{10}{100}\times x[/tex]

                                                                               = [tex]x-0.1x[/tex]

                                                                               = 0.9x

Number of customers using landlines in 2004 =  [tex]0.9x-\frac{10}{100}\times 0.9x[/tex]

                                                                              = [tex]0.9x-0.1\times0.9x[/tex]

                                                                              = [tex]0.9x-0.09x[/tex]

                                                                              = [tex]0.81x[/tex]

Answer:

Answer is m∠4=40

Step-by-step explanation:

According to the image which i have posted below,we first want to take note that m∠6 & m∠7 are vertical angles. Vertical angles are equal to each other, therefore m∠6 is equal to m∠7.

m∠6 = m∠7 (vertical angles)

11x + 8 = 12x – 4

12x - 11x = 8 + 4

x = 12

so

m∠6 = 11x + 8  

m∠6 = 11(12) + 8

m∠6 = 132 + 8

m∠6 = 140

m∠4 = 180 - m<6

m∠4 = 180 - 140

m∠4 = 40

Answer is m∠4=40....

Answer:

He needs to get 1 right

Step-by-step explanation:

1/40 is equal to .025. This means the other 39/40 incorrect ones are worth .975(97.5%). If we multiply the .975 by the 15 percent of his overall grade, we get 14.625. When you subtract this from the overall grade, you get 70.075, which is just above a 70%.

For this case we have that the general qualification is 70, of it Evan has accumulated 84.7%. Making a rule of three:

70 ----------> 100%

x -------------> 84.7%

Where "x" represents the rating that Evan has accumulated:

[tex]x = \frac {84.7 * 70} {100}\\x = 59.29\\70-59.29 = 10.71[/tex]

Evan is missing 10.71 to get 70.

In percentage, we have to:

100% -84.7% = 15.3%

Now we have that the exam represents 15% of the grade, this is divided into 40 questions.

It is observed that Evan must correctly answer the 40 questions of the exam, so he would get 15%. Even so, it would lack a 0.3% note to reach 70.

Answer:

He must answer the 40 questions correctly.

I calculated this by 3200/5

Is this appropriate?

Answer:

C(x) =24+6(z-1) where z is the total of units sold.

Therefore if z=10 units, the answer is: C(x)=24+6(10-1)

Or 24+6(9)

Or $78

Step-by-step explanation:

Answer:

10 Units would cost $78

Step-by-step explanation:

We will be using the following equation to solve this problem

[tex]C(x) = 24+6(x-1)[/tex]

Where x will be the amount of units of coverage that are sold. The equation subtracts 1 from the amount of units sold (since the first unit costs $24) and multiplies that by $6 which is the cost per unit. Then it adds $24 to that, which gives us the total cost.

Since we sold 10 units of coverage we plug that into the equation

[tex]C(10) = 24+6(10-1)[/tex]

[tex]C(10) = 24+6(9)[/tex]

[tex]C(10) = 24+54[/tex]

[tex]C(10) = 78[/tex]

So 10 units of coverage sold would cost $78

Answer:

We know that the formula to mix chemical solutions is: C1V1 = C2V2

where C represents the concentration of the solute, and V represents volume in milliliters or ml.

In this case, we have:

0.06V1 = 0.15×350

Solving for 'V1' we have:

V1 = (0.15×350)/0.06 = 52.5/0.06 = 875

Therefre I can make 875 mL of a 6% solution by diluting 350 mL of a 15% solution.

Answer:

y = 1/3x -8

Step-by-step explanation:

3x+y=−5

First we need to get the equation in slope intercept form to find the slope

Subtract 3x from each side

3x-3x+y=-3x−5

y = -3x-5

The slope is -3

We want a line perpendicular.  Perpendicualr lines have slopes that are the negative reciprocal.  Take the negative reciprocal

m new = - (1/-3) = 1/3

The slope of the new line is 1/3

We have the slope (1/3) and a point (3,-7)

We can use the point slope form for the equation of a line

y-y1 = m(x-x1)

y--7 = 1/3 (x-3)

y+7 = 1/3 (x-3)

or if we want the slope intercept form

Distribute

y+7 = 1/3x -1

Subtract 7 from each side

y+7-7 = 1/3x -1-7

y = 1/3x -8
