Go online and use this very good graphing calculator:

The probability is approx.=67/1518=~.044137......... Can you guys come up with EXACT probability?.

\(y=2\times(1-{x}^{2})\)

\(y=2-{2x}^{2}\)

\(y={-2x}^{2}+2\)

x-intercepts:

\(0=-{2x}^{2}+2\)

\(-2={-2x}^{2}\)

\(1={x}^{2}\)

\(±1=x\)

\(x=±1\)

\(x=1\) and \(x=-1\)

\((1,0)\) and \((-1,0)\)

y-intercept:

\(y=-{2(0)}^{2}+2\)

\(y=-2(0)+2\)

\(y=0+2\)

\(y=2\)

\((0,2)\)

Graph:

the parentheses around the 9-4

\(\frac{2}{3n}-\frac{2}{3}=\frac{n}{6}+\frac{4}{3}\)

\(\frac{6}{9n}-\frac{6n}{9n}=\frac{n}{6}+\frac{4}{3}\)

\(\frac{6-6n}{9n}=\frac{n}{6}+\frac{4}{3}\)

\(\frac{6-6n}{9n}=\frac{2n}{12}+\frac{16}{12}\)

\(\frac{6-6n}{9n}=\frac{2n+16}{12}\)

\(6-6n=\frac{9n\times(2n+16)}{12}\)

\(6-6n=\frac{3n\times(2n+16)}{4}\)

\(4\times(6-6n)=3n\times(2n+16)\)

\(24-24n=3n\times(2n+16)\)

\(24-24n={6n}^{2}+48n\)

\(24={6n}^{2}+72n\)

\(4={n}^{2}+12n\)

\(40={n}^{2}+12n+36\)

\(40={(n+6)}^{2}\)

\(±2\sqrt{10}=n+6\)

\(-6±2\sqrt{10}=n\)

\(n=-6±2\sqrt{10}\)

\(n=-6+2\sqrt{10};\)  \(n≈ 0.3245553203367587\)

\(n=-6-2\sqrt{10};\)  \(n≈-12.3245553203367587\)

8 is the answer

\(-(2+2m)-2>6\)

\(-2-2m-2>6\)

\(-4-2m>6\)

\(-2m>10\)

\(m<-5\)

That is correct.

Solve for n:             (2/3)n - 2/3 = n/6 + 4/3. I have taken the 1st. term as shown
(2 n)/3-2/3 = n/6+4/3

(2 n)/3-2/3 = (2 n-2)/3:
(2 n-2)/3 = n/6+4/3

Put each term in n/6+4/3 over the common denominator 6: n/6+4/3  =  n/6+8/6:
(2 n-2)/3 = n/6+8/6

n/6+8/6 = (n+8)/6:
(2 n-2)/3 = (n+8)/6

Multiply both sides by 6:
(6 (2 n-2))/3 = (6 (n+8))/6

6/3 = (3×2)/3 = 2:
2 (2 n-2) = (6 (n+8))/6

(6 (n+8))/6 = 6/6×(n+8) = n+8:
2 (2 n-2) = n+8

Expand out terms of the left hand side:
4 n-4 = n+8

Subtract n from both sides:
(4 n-n)-4 = (n-n)+8

4 n-n = 3 n:
3 n-4 = (n-n)+8

n-n = 0:
3 n-4 = 8

Add 4 to both sides:
3 n+(4-4) = 8+4

4-4 = 0:
3 n = 8+4

8+4 = 12:
3 n = 12

Divide both sides of 3 n = 12 by 3:
(3 n)/3 = 12/3

3/3 = 1:
n = 12/3

The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:
Answer: |  n = 4

There are a lot of errors in your question!!!. For example, you say "Them 22 minutes after you left, he was 34 minutes from her house" What does that mean? Why can't you copy the question as it is written down? In the above quote, after 22 minutes he must have been 34 MILES not 34 MINUTES from her house.

At any rate, 10 minutes after he left his house, he was 40 miles from her house, which means he covered that 40 miles in 90 - 10=80 minutes. So, his speed was:40 miles/80 minutes or 1/2 mile per minute. Or 30mph.

Therefore, he must have covered the distance to his grandmother's house in 90 minutes x 1/2 mile per minute=45 miles, which is the distance between his house and his grandmother's.

thank you !!! 

{5 7/8, 6 1/2, 6 7/10, 6 3/4}    from least to greatest.

No,     it's   19

- 1/6       just use the calculator !          is  - .1666666666...   repeating...

Pretty poor advice !

Some of the water molecules have enough energy to vaporize  even though the AVERAGE temperature is 98 c  (which is VERY close to boiling)  ...also if the pressure is lower than standard, the boiling point will be lower.....

Figured it out just now it was supposed to be factor in the form of 

[6cos 10 - 8 cos^3 10]^2

Thx for your response !

Sry ! it seems i mistyped the power of the cos a little bit, can you please help me again ?
 

36 cos^2 [10] - 96 cos^4 [10] + 64 cos^6 [10]

Thx !
