<h3>Answer: (6, -2)</h3>

Explanation:

The two given points have x coordinates of x = 6 each. They add to 6+6 = 12. Divide this in half to get 12/2 = 6. Since the x coordinates were both the same, the midpoint x coordinate is the same as well.

The y coordinates are a bit more interesting. Add them up to get -5+1 = -4. Then cut this in half to get -4/2 = -2. The y coordinate of the midpoint is -2.

Overall, the midpoint is (6, -2)

The price-to-earning ratio for firms in a given industry is distributed according to normal distribution. In this industry, a fi

dmitriy555 [2]

Answer:

Option a) Has an above average price-to-earning ratio

Step-by-step explanation:

We are given the following in the question:

The price-to-earning ratio for firms in a given industry is distributed according to normal distribution.

For a particular firm the ratio x has a standard normal variable has a value,

z = 1

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

$1 = \dfrac{x - \mu}{\sigma}\\\\\sigma = x - \mu\\x = \mu + \sigma$

Thus, the firm has an above average price-to-earning ratio as the ratio is one standard deviation above the mean.

Option a) Has an above average price-to-earning ratio

Simplify (4x^4y^3)^3/3(5x^2y^6)^2

jolli1 [7]

Answer: Hence, our simplified form will be :

$\frac{64}{75}x^8y^{-3}$

Step-by-step explanation:

Since we have given that

$\frac{(4x^4y^3)^3}{3(5x^2y^6)^2}$

We need to simplify the above expression:

$\frac{(4x^4y^3)^3}{3(5x^2y^6)^2}\\\\=\frac{4^3x^{4\times 3}y^{3\times 3}}{3\times 5^2x^{2\times 2}y^{6\times 2}}\\\\=\frac{64x^{12}y^9}{3\times 25x^4y^{12}}\\\\=\frac{64x^{12}y^9}{75x^4y^{12}}\\\\=\frac{64}{75}x^{12-4}y^{9-12}\\\\=\frac{64}{75}x^8y^{-3}$

Hence, our simplified form will be :

$\frac{64}{75}x^8y^{-3}$

Work out 5 x 10^6 / 4 x 10^4<br> Give your answer as an ordinary number.

Angelina_Jolie [31]

Answer:

$1.25 \times {10}^{2} = 125$

Step-by-step explanation:

$\frac{5 \times {10}^{6} }{4 \times {10}^{4} } = \frac{5}{4} \times \frac{ {10}^{6} }{ {10}^{4} } = 1.25 \times {10}^{2} = 125$

Is this right I need help with this

Margarita [4]

Y axis is counting by 2's
it started at 2 and went up to 6
Y = 4

X axis is counting by 2'2
starts at one goes to 3
X = 2

Slope is 4/2 because rise over run
4/2 = 2
Slope is simplified to 2.

Solve 28 + 7y =91<br><br>Y=.....

Anna35 [415]

Answer:

$y = 9$

Step-by-step explanation:

$28 + 7y = 91 \\ 7y = 91 - 28 \\ 7y = 63 \\ \frac{7y}{7} = \frac{63}{7} \\ y = 9$
