Answer:

a)   [tex]P(S)=\frac{15}{28}[/tex]

b)   [tex]P(D)=\frac{13}{28}[/tex]

Step-by-step explanation:

From the question we are told that:

Bag A   [tex]W=4\\\\ Q=3[/tex]

Bag Q   [tex]W'=5\\\\ Q'=2[/tex]

Generally the equation for Probability of drawing W&B balls is mathematically given by

Bag A

[tex]P(W)=\frac{4}{7}P(Q)=\frac{3}{7}[/tex]

Since Ball is drawn and added to Bag Q

Bag Q

[tex]P(W)'=\frac{6}{8}\\\\ Q(B)'=\frac{2}{8}[/tex]

a)

Generally the equation for Probability of being the same is mathematically given by

[tex]P(S)=(P(W)*P(W'))+(P(B)*P(B)')[/tex]

[tex]P(S)=(\frac{4}{7}*\frac{6}{8})+(\frac{3}{7}*\frac{2}{8})[/tex]

[tex]P(S)=\frac{15}{28}[/tex]

b)

Generally the equation for Probability of NOT being the same is mathematically given by

[tex]P(D)=P(W)+P(B)'+(P(B)*P(W'))[/tex]

[tex]P(D)=(\frac{4}{7}*\frac{2}{8})+(\frac{3}{7}*\frac{6}{8})[/tex]

[tex]P(D)=\frac{13}{28}[/tex]

Answer:

1) "fake numbers" do not exist but there are irrational numbers

2) We have negative numbers to help us understand the number system better. We need negative numbers in graphing.

Answer:

both 2 and -2

Step-by-step explanation:

Substitute 4 for r(x) on the given equation.

[tex]4=x^2[/tex]

[tex]\sqrt{4} =\sqrt{x^2}[/tex]

[tex]x=2[/tex]

[tex]x=-2[/tex]

Answer:

.094

Step-by-step explanation:

5/11 is .455

11 total marbles 5 are green

but thats the probability of just one draw

so .455 x .455 x .455 is .094 for three separate draws

Answer:

answer is 230

Step-by-step explanation:

they need more than 800 so u take 800-571 which is 229 u then add one because u need at least one more than 800 which is 230.

Answer:

230.  

Step-by-step explanation:

You need more than 800 so you take 800 and talk away 71 which is 229, and then add 1 because you need at least one more than 800 , and you get an answer 230.  

Answer:

100π

Step-by-step explanation:

Area of a circle formula: πr²

The radius would be half of 20 m

So the radius, r is 10 m

Plug that in

πr²=π·10²=100π

Answer:

The fraction 53 9 is equivalent to 5 8 9.

Step-by-step explanation:

This fraction is a improper fraction once the absolute value of the top number or numerator (53) is greater than the absolute value of the bottom number or denomintor (9). So, the equivalent fraction is a mixed number which is made up of a whole number (5) and a proper fraction ( 8 9 ).

[tex]53 \frac{9}{10}[/tex]

53.9 can be split into 53 and .9

53 is the whole number

.9 is in the tenths place so it can be written out of 10: [tex]\frac{9}{10}[/tex]

It doesn't need to be simplified leaving us with 53 [tex]\frac{9}{10}[/tex]

Answer:

6

Step-by-step explanation:

An array will have would constitute the shape of a parallelogram, in which you are essentially solving for s₁ and s₂. Note that there are 32 miniature cars in all, in which both sides, when multiplied, must result in said number:

32 x 1 = 32

2 x 16 = 32

4 x 8 = 32

8 x 4 = 32

16 x 2 = 32

1 x 32 = 32

There are 6 ways for Evan to create a array of 32 miniature cars.

Answer:

5 years

Step-by-step explanation:

To determine the number of years needed for the company to process a certain amount of milk, we use the given function which relates the number of years, x, and the gallons of milk, y. We simply substitute the number of gallons to y and solve for x.  

y = x^6 − 9x^4 + 70x^2

630 = x^6 − 9x^4 + 70x^2

Solving for x, we will have

x = 4.8866 years or approximately 5 years

Hope this answer helps you :)

Answer:

[tex]y=-x+16[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

y=x-9

Rewrite the equation

y=1x-9

Now, we can identify clearly that the slope of the line is 1. The negative reciprocal of 1 is -1, so therefore, the slope of a perpendicular line would be -1. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-1x+b\\y=-x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-x+b[/tex]

Plug in the given point (7,9) and solve for b

[tex]9=-7+b[/tex]

Add 7 to both sides to isolate b

[tex]9+7=-7+b+7\\16=b[/tex]

Therefore, the y-intercept is 16. Plug this back into [tex]y=-x+b[/tex]:

[tex]y=-x+16[/tex]

I hope this helps!

Answer:

10 people can go to the amusement park

Step-by-step explanation:

363 - 5.50 = 357.5

357.5 / 35.75 = 10

Answer:

The reason why it isnt true is because you cannot combine exponents that have different bases.

Step-by-step explanation:

So, with the problem shown below, it is [tex]3^5*2^4[/tex]

This cannot be multiplied.

To get [tex]6^9[/tex], you would need 6^4*6^5

So basically, its like ths:

If two exponents have to same base, they can be added together. THis adds the exponents, but leaves the bases the same.

If two exponents have different bases, they cannot be added together. You would have to distrubute both the numbers exponents then multiply them together.

For instance, with [tex]3^5*2^4[/tex], you would have to make it 243+16

This would equal 259.

As we can see, [tex]6^9[/tex] is over 10 million, much bigger than this.

I hope this makes sense and helps!

Answer:A

Step-by-step explanation:

Answer:

hypotenuse = 7.3

Step-by-step explanation:

here 7 and 2 are the legs og the right triangle .we should find hypotenuse.

let the legs of the right triangle be a nd b respectively . And c be hypotenuse

using pythagoras theorem to find hypotenuse

a^2 + b^2 = c^2

7^2 + 2^2 = c^2

49 + 4 = c^2

53 = c^2

[tex]\sqrt{53}[/tex] = c

7.28 = c

7.3 =c

Answer:

7.3

Step-by-step explanation:

[tex]7^{2} + 2^{2} = x^{2} \\ 53 = x^{2}\\\sqrt{53} = \sqrt{x^{2}} \\x = 7.3[/tex]

*figure of the face of each stone is shown on the attachment below

Answer:

66 square inches

Step-by-step explanation:

Area of the trapezoid = ½(a + b) × h

Where,

a = 14 inches

b = 8 inches

h = 6 inches

Plug in the values into the trapezoid area formula

Area of the trapezoid = ½(14 + 8) × 6

= ½(22) × 6

= 11 × 6

Area of the trapezoid = 66 square inches

Answer:

[tex]y =120*1.1^x[/tex]

[tex]r = 10\%[/tex] --- Percentage increase

Step-by-step explanation:

Given

Let

[tex]x \to months[/tex]

[tex]y \to mice[/tex]

So, we have:

[tex](x_1,y_1) = (0,120)[/tex] --- Monday

[tex](x_2,y_2) = (1,132)[/tex] --- One month later

Required

The function

The function is represented as:

[tex]y = ab^x[/tex]

In [tex](x_1,y_1) = (0,120)[/tex], we have:

[tex]120 =a * 1[/tex]

[tex]120 =a[/tex]

Rewrite as:

[tex]a = 120[/tex]

In [tex](x_2,y_2) = (1,132)[/tex], we have:

[tex]132 = a * b^1[/tex]

[tex]132 = a * b[/tex]

Substitute [tex]a = 120[/tex]

[tex]132 = 120 * b[/tex]

Solve for b

[tex]b = \frac{132}{120}[/tex]

[tex]b = 1.1[/tex]

Recall that:

[tex]y = ab^x[/tex]

Hence, the function is:

[tex]y =120*1.1^x[/tex]

To get the monthly percentage increase (r), we have:

[tex]y = a(1 + r)^x[/tex]

Compare to: [tex]y = ab^x[/tex]

So:

[tex]1+r =b[/tex]

Make r the subject

[tex]r = b-1[/tex]

[tex]r = 1.1-1[/tex]

[tex]r = 0.1[/tex]

Express as percentage

[tex]r = 0.1*100\%[/tex]

[tex]r = 10\%[/tex]

Answer:

Perimeter of figure = 68 centimeter

Step-by-step explanation:

Given information:

Width of side = 12 centimeter

Length of side =  22 centimeter

Find:

Perimeter of figure

Computation:

Perimeter of rectangle = 2[l + b]

Perimeter of figure = 2[Width of side + Length of side ]

Perimeter of figure = 2[12 + 22]

Perimeter of figure = 2[34]

Perimeter of figure = 68 centimeter
