A bag of marbles has 4 Red and 3 Green marbles. You pick from the bag, replace the marble and then pick again. What is the probability of picking red both times?

A. 16/49
B. 12/42
C. 4/7

Answer:

Step-by-step explanation:

x + 2y = 7   ⇒  x = 7 - 2y

- 2x + 3y = 14

- 2(7 - 2y) + 3y = 14

-14 + 4y + 3y = 14

-14 +7y +14 = 14 +14

   7y = 28

     y = 4

x = 7 - 2y = 7-2(4) = 7 - 8 = -1

-5/2 is the slope of thosr points

Answer:

y = 5x + 3 I just learned this 2 years ago.

Explanation: The y intercept is the beginning of the equation and I'm sure you know y = mx + b, so you take the slope (5) and add x to it, because that is the slope, and add 3 to it because that is y intercept.

Answer:

[tex]g^{-1}(x)=1+10^{x/2}[/tex]

Step-by-step explanation:

Inverse Function

Let's call:

[tex]y=2 log(x-1)[/tex]

Divide by 2:

[tex]y/2=log(x-1)[/tex]

Assuming the base of the log is 10, apply exponential base 10:

[tex]10^{y/2}=x-1[/tex]

Solving for x:

[tex]x=1+10^{y/2}[/tex]

Swap variables:

[tex]y=1+10^{x/2}[/tex]

Calling this function the inverse:

[tex]\boxed{g^{-1}(x)=1+10^{x/2}}[/tex]

Answer:

[tex]A=5024\ cm^2[/tex]

Step-by-step explanation:

Father will make an ornamental fish pond. The pool is circular with a diameter of 80 cm, the area of ​​land needed to make a pool is ??

The diameter of a circular pool, d = 80 cm

It means that,

Radius, r = d/2

r = 40 cm

We need to find the area of the land needed to make a pool. The area of a circular path is given by :

[tex]A=\pi r^2[/tex]

Put the values in the above formula.

[tex]A=3.14\times (40)^2\\\\A=5024\ cm^2[/tex]

So, it will require [tex]5024\ cm^2[/tex] area of land to make a pool.

Answer:

(x - 12)(x + 2)

Step-by-step explanation:

Given

x² - 10x - 24

Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 10)

The factors are - 12 and + 2 , since

- 12 × + 2 = - 24 and - 12 + 2 = - 10 , thus

x² - 10x - 24 = (x - 12)(x + 2) ← in factored form

Answer:

x = 32

Step-by-step explanation:

So we are given the measures of two of the three interior angles. 98° and 50°. We are also given that the value of the third interior angle is equal to x°. Remember, the sum of the interior angles of a triangle is 180°. Knowing this, we can make the equation:

x + 98 + 50 = 180

Now we solve for x. Subtract 50 from both sides.

x + 98 = 130

Subtract 98 from both sides.

x = 32

So the value of x is 32.

Answer:

[tex]=-1\frac{5}{9}[/tex]

Step-by-step explanation:

We want to write:

[tex]-1.\bar{5}[/tex]

As a mixed number in the simplest form.

We can use the following algebraic trick. First, we can ignore the negative and add it on the very end. So, we have the number:

[tex]1.55555...[/tex]

Let's let this equal to n. So:

[tex]1.55555...=n[/tex]

Now, we will multiply n by 10^x for the number of repeating digits x.

There is only one digit repeating (the 5). So, we will multiply both sides by 10^1 or just 10. This yields:

[tex]15.55555...=10n[/tex]

Now, we will subtract n from both sides. This yields:

[tex]15.5555...-n=10n-n[/tex]

On the right, we will just get 9n.

However, let's replace n with 1.5555... on the left. This yields:

[tex]15.5555...-1.5555...=9n[/tex]

All of the repeatings 5s will cancel. 15-1 is 14. So:

[tex]14=9n[/tex]

Now, divide both sides by 9. So, our n is:

[tex]n=\frac{14}{9}[/tex]

And since we originally set n to be 1.5 repeating, this is equivalent to:

[tex]n=1.\bar{5}=\frac{14}{9}[/tex]

And now, we can add back the negative:

[tex]-1.\bar{5}=-\frac{14}{9}[/tex]

We can rewrite this as:

[tex]=-(\frac{9}{9}+\frac{5}{9})[/tex]

So, as a mixed fraction, our decimal is:

[tex]=-1\frac{5}{9}[/tex]

And we're done!

Answer:

The total amount is 1214.4

Step-by-step explanation:

Given

principal p=$1200

interest rate r= 12%= 12/100= 0.12

time t= 1

n= 12

we know that the compound interest formula is

A=p(1+r/n )^nt

A=1200(1+0.12/12)^1*12

A=1200(1+0.01)^12

A=1200(1.001)^12

A=1200*1.012

A=1214.

Answer:

Correct answers:

$2928$

Step-by-step explanation:

$2928$

We express the interest r in decimal form, so we have r=12%=12100=0.12. The principal is P0=$1,200, so the interest is I=P0⋅r⋅t=$1,200⋅0.12⋅12=$1,728. The interest paid is $1,728, so the total amount repayable is $1,200+$1,728=$2,928.

Answer:

x = 2

Step-by-step explanation:

To start, you want to isolate x.

To do so, get all the x terms to one side.

2x + 1 = 4x - 3

Subtract -4x on both sides.

-2x + 1 = -3

Then, subtract 1 on both sides.

-2x = -4

Finally, divide -2 on both sides.

x = 2

Answer:

The answer is negative one half. If I am wrong let me know because the picture is a little hard to read.

Step-by-step explanation: To find the slope, you look at the Y axis and see where the line crosses perfectly(or goes through) the Y axis first. Then, you look at the x axis and see where the line crosses perfectly on the x axis. For example, the line crosses the Y axis at negative, and the line crosses the X axis at positive 2.  The vertical line is the y axis and the horizontal line is the x axis.

Step-by-step explanation:

answer: 68

work:

all you basically do is just divide 272 by 4

If Ralph drove 272 miles in 4 hours then 68 miles per hour is the average speed

A division is a process of splitting a specific amount into equal parts.

Given that Ralph drove 272 miles in 4 hours

We need to find his average speed

The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time

Speed=Distance/ Time

Average speed=272/4

=68 miles per hour

Hence, if Ralph drove 272 miles in 4 hours then 68 miles per hour is the average speed
