Answer: (-1, 2)

Step-by-step explanation:

<u>It's a counter-clockwise rotation, that means (x, y) changes to (y, -x).</u>

(-2, -1) ⇒ (-1, -(-2)) ⇒ (-1, 2)

<u>If it's a clockwise rotation, then (x, y) will change to (-y, x)</u>

(-2, -1) ⇒ (-(-1), -2) ⇒ (1, -2)

On a quiz there are four multiple-choice questions worth 3 points each and two true/false questions worth 1 point each. Each mul
Pani-rosa [81]

Answer: Expected value would be \dfrac{17}{5}

Step-by-step explanation:

Since we have given that

Number of multiple choice question = 4

Number of true false questions = 2

Number of points for each multiple choice question = 3

Number of points for each true false question = 1

Number of choices in multiple choice = 5

Probability of getting correct answer in multiple choice question = \dfrac{1}{5}

Probability of getting correct answer in true false question = \dfrac{1}{2}

Expected value of the student's score on the test would be

E(x)=\sum xp(x)\\\\E(x)=4\times 3\times \dfrac{1}{5}+2\times 1\times \dfrac{1}{2}\\\\E(x)=\dfrac{12}{5}+1\\\\E(x)=\dfrac{12+5}{5}=\dfrac{17}{5}

Hence, expected value would be \dfrac{17}{5}

Aleksandr [31]
Here is the formula you'll need
Total = Principal * (1 + (rate/n))^n*years
I don't know how to solve that for "n" so we'll use trial and error.

If compounded annually, total = <span> <span> <span> 10,841.24 </span> </span> </span>
If compounded quarterly, total = <span> <span> <span> 10,955.64 </span>
</span></span><span>If compounded monthly, total = </span> <span> <span> <span> 10,981.82 </span> </span> </span>
If compounded daily, total = <span> <span> <span> 10,994.58 </span> </span> </span>
Therefore the answer is "A", daily.

Find 5g(x)-f(x) given f(x)=9x^2+7x and g(x)=2-x
givi [52]

Answer:

- 9x² - 12x + 10

Step-by-step explanation:

5g(x) - f(x)

= 5(2 - x) - (9x² + 7x) ← distribute both parenthesis

= 10 - 5x - 9x² - 7x ← collect like terms

= - 9x² - 12x + 10
