Answer:

(-2,-1)

Step-by-step explanation:

Midpoints are found when you do ([x(subscript A) + x(subscript B)]/2, [y(subscript A) + y(subscript B)]. Therefore your equation (for x of B) should look like this:

-4 = ([-6+x]/2)

After you solve for x, you should have gotten -2 for x.

Then you do the same for y:

2 = ([5+y]/2)

You should get -1. Your final answer should be (-2, -1)

Answer:

0.9375 ; 0.5

Step-by-step explanation:

Given that :

p = 0.5

Probability model for the Number of girls the couple has :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x = 0) = 4C0 * 0.5^0 * 0.5^4 = 0.0625

P(x = 1) = 4C1 * 0.5^1 * 0.5^3 = 0.25

P(x = 2) = 4C2 * 0.5^2 * 0.5^2 = 0.375

P(x = 3) = 4C3 * 0.5^3 * 0.5^1 = 0.25

P(x = 4) = 4C4 * 0.5^4 * 0.5^0 = 0.0625

Probability of having atleast one girl

Number of trials, n = 4

P(x ≥ 1) = p(x = 1) + p(x = 2) + p(x = 3) + p(x = 4)

Using the relation :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

Using calculator ;

P(x ≥ 1) = 0.9375

Probability of having exactly one boy or exactly one girl

1 boy 3 girls OR 1 girl 3 boys

P(x = 1)

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x = 1) = 4C1 * 0.5^1 * 0.5^3

P(x = 1) = 4 * 0.5 * 0.125

P(x = 1) = 0.25

The probability of having one girl, 3 boys and vice versa is 0. 25

Hence, Probability of having exactly one boy or exactly one girl

0.25 + 0.25 = 0.5

Answer:

4,000,000

Step-by-step explanation:

We start by subtracting his salary (20k) from his annual income. That means he got 100,000 from selling homes.

So, what is 100,000 2.5% of?

I used the equation:

100,000 = .025x

with x being the value of all the homes.

Just divide and conquer, and you end up with a final answer of 4 Million

Answer:

3/10 of the yard in one hour

Step-by-step explanation:

[tex]3/5(1/2)=3/10[/tex]

Answer:

3/10 of the yard.

Step-by-step explanation:

What we know:

Ryan can mow 3/5 of a yard in 2 hours.

What we need to know:

How much of the yard Ryan can mow in 1 hour, so the unit rate.

How do we do this:

It's simple if you think about it.

Just divide 3/5 by 2 (or multiply by 1/2)

3/5 * 1/2

3/(5*2)

3/10 of the yard can be mowed in one hour.

Answer:

x=24,sorry if im wrong:/

Step-by-step explanation:

Answer:

24

Step-by-step explanation:

0.6x - 5 = 0.1x + 7

-0.1x          -0.1x

0.5x - 5 = 7

0.5x = 12

(2)0.5x = 12(0.5)

x=24

Answer:

$3.25

Step-by-step explanation:

So,

If a package of 17 sliced apples is $2.21, lets find out the price per apple.

2.21 / 17 = 0.13

so, the price per apple is $0.13

Now, we find the price of a package with 25 sliced apples.

0.13 x 25 = 3.25

So, the price of a package with 25 sliced apples is $3.25

Hope this helps!

Answer:

The sum of the interior angles of any triangle are equal to 180

therefore in this triangle, m<a+m<c+m<b=180

we know that 9x-26 and m<a are supplementary angles (meaning they add to 180) and therefore,

9x-26+a=180

9x+a=206

a=206-9x

(206-9x)+(2x-12)+(4x+43)=180

combine like terms

-3x+237=180

-3x=-57

x=19

if x=19 then we can substitue it in for c

4x+43=c

4(19)+43=c

c=119

Answer:

Step-by-step explanation:

The result of 490 divided by 7 is 70.

To calculate 490 divided by 7, we can perform long division as follows:

        70

   __________

7  |  490

   -  49  (7 times 7)

   _______

         0  (no remainder)

In the first step, we divide 7 into the first digit of 490, which is 4. The quotient is 0, and we bring down the next digit, which is 9.

Next, we divide 7 into 49. The quotient is 7, and there is no remainder.

Therefore, the answer to 490 divided by 7 is 70.

Answer:

The equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line is:

Step-by-step explanation:

We know the slope-intercept form of the line equation

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

Given the line

[tex]y=34x-8[/tex]

comparing with the slope-intercept form of the line equation

The slope m = 34

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:  

slope = m = 34

Thus, the slope of the the new perpendicular line = – 1/m = -1/34 = -1/34

Using the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values of slope = -1/35 and the point (12, 5)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-5=-\frac{1}{34}\left(x-12\right)[/tex]

Add 5 to both sides

[tex]y-5+5=-\frac{1}{34}\left(x-12\right)+5[/tex]

[tex]y=-\frac{1}{34}x+\frac{91}{17}[/tex]

Therefore, the equation in slope-intercept form of the line that passes through the point (12, 5) and is perpendicular to the line is:
