Find the distance between the two points -2,2 and 2,-1. Show your work

Alex

(-2,2) (2,-1)

You can use Pythagorean theorem to solve this:

$a^{2} +b^{2} =c^{2}$

$3^{2} + 4^{2} =c^{2}$

9 + 16= $c^{2}$

25 = $c^{2}$

$\sqrt{25} =\sqrt{c^{2} }$

c = 5

^^^This means that the length between the two points is 5 units

Hope this helped! Let me know if there is anything else I can do!

Which expression is equivalent to (4(5^3)1/2?

Feliz [49]

Answer:

$10\sqrt{5}$

Step-by-step explanation:

In this problem, we are given expression in exponent form and we have to simplify the expression.

The expression is $[4(5^{3} )]^{\frac{1}{2} }$

Now, we know that $5^{3} = 5 \times 5 \times 5 = 125$

So, $4(5^{3} ) = 4 \times 125 = 500$

Now, 500 can be written as 100 × 5 = 10² × 5

Therefore, $[4(5^{3} )]^{\frac{1}{2} } = (500)^{\frac{1}{2} } = 10\sqrt{5}$ {Since 500 = 100 × 5 = 10² × 5} (Answer)

Assume that all grade-point averages are to be standardized on a scale between 0 and 6. How many grade-point averages must be

yanalaym [24]

Answer:

The sample size 'n' = 72,030

Step-by-step explanation:

Step(i):-

Given that the Estimate Error = 0.013

Given that the standard deviation of the Population = 1.5

The estimated error is determined by

$E = \frac{Z_{0.98} S.D }{\sqrt{n} }$

Step(ii):-

Given that the Level of significance = 0.98 or 0.02

Z₀.₀₂ = 2.326

The estimated error is determined by

$E = \frac{Z_{0.98} S.D }{\sqrt{n} }$

$0.013 = \frac{2.326 X 1.5 }{\sqrt{n} }$

$\sqrt{n} = \frac{3.489}{0.013} = 268.38$

Squaring on both sides, we get

n = 72,030

Final answer:-

The sample size 'n' = 72,030
