<u>Answer</u>:

n + n + 2 ≥ 76

<u>Explanation</u>:

To find odd numbers, we have to use n + n + 2

For example let the number be 1, the 1 + 2 = 3, 3 + 2 = 5.

Therefore, used: n + n + 2 expression and it should be equals or at least 76. so finally n + n + 2 ≥ 76 applies.

Find the limit, if it exists. (if an answer does not exist, enter dne.) lim (x, y) → (0, 0) x4 − 20y2 x2 + 10y2

Firdavs [7]

Traveling along the x-axis, we have

$\displaystyle\lim_{(x,y)\to(0,0)}\frac{x^4-20y^2}{x^2+10y^2}=\lim_{x\to0}\frac{x^4}{x^2}=\lim_{x\to0}x^2=0$

On the other hand, along the y-axis we get

$\displaystyle\lim_{(x,y)\to(0,0)}\frac{x^4-20y^2}{x^2+10y^2}=\lim_{y\to0}\frac{-20y^2}{10y^2}=\lim_{y\to0}(-2)=-2$

Therefore the limit doesn't exist.

There are 30 total cards. 10 are yellow. What are the chances that you pull 2 yellow cards.

Hoochie [10]

Answer: please read the steps

Step-by-step explanation:

To calculate percentage the odds of pulling 2 yellow cards out of 30 is 2/30. now we turn the denominater into 100

100/30= 3.33...

3.33*2=6.66.. (round to nearest tenth)

now you have 6.7/100 which is

6.7% chance

(if you need more precise number its 6.667%)
