Answer:

2

Step-by-step explanation:

slope=y1-y2/x1-x2

3-(-5)/2-(-2)=8/4

=2

To find the slope, subtract the y values over the x values.

3 -  - 5 / 2 - - 2 > <em>Remember subtracting a negative is the sam as adding positives, so this can be rewritten as </em><em>3 + 5 / 2 + 2 .</em>

<em />

<em>3 + 5 / 2 + 2 </em>> <em>8 / 4</em> > <u>2</u>.

This means the slope between the two points is <u>2</u>!

Suppose SAT Writing score are normally distributed a mean of 497 and a standard deviation of 114. A university plans to admit st
Olin [163]

Answer:

The minimum score required for admission to the nearest whole number = 557

Step-by-step explanation:

We solve this using z score formula.

z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

Top 30% of the candidates is a ranking that is equivalent to = 100 - 30% = 70th percentile.

The z score of 70th percentile = 0.524

Mean = 497

Standard deviation of 114.

Minimum score = raw score = ???

Hence:

0.524 = x - 497/114

Cross Multiply

0.524 × 114 = x - 497

59.736 = x - 497

x = 59.736 + 497

x = 556.736

The minimum score required for admission to the nearest whole number = 557

Show that a^12 can be written as a perfect square and a perfect cube
Elden [556K]

Answer:

Step-by-step explanation:

Doing this the long way, write a^12 as a product of "a"s

a^12 = a * a * a * a * a * a * a * a * a * a * a * a

Now group them into groups of 4

a^12 = a * a * a * a * a * a * a * a * a * a * a * a

There are 3 groups of 4 so you can write it as [(a^4)]^3 which is a cube

Now do the same thing with groups of 6s

a^12 = a * a * a * a * a * a * a * a * a * a * a * a

a^12 = (a^6)^2

So the two answers are

Perfect cube:  [(a^4)]^3

Perfect square: (a^6)^2
