Answer:
The slope of line is 0 given points (2,8)(7,8)
Step-by-step explanation:
We need to find slope of line given points (2,8),(7,8)
The formula used to find slope of line is: ![Slope=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=Slope%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We are given:
![x_1=2, y_1=8, x_2=7 \ and \ y_2=8](https://tex.z-dn.net/?f=x_1%3D2%2C%20y_1%3D8%2C%20x_2%3D7%20%5C%20and%20%5C%20y_2%3D8)
Finding slope using formula:
![Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-8}{7-2}\\Slope=\frac{0}{5}\\Slope=0](https://tex.z-dn.net/?f=Slope%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5CSlope%3D%5Cfrac%7B8-8%7D%7B7-2%7D%5C%5CSlope%3D%5Cfrac%7B0%7D%7B5%7D%5C%5CSlope%3D0)
So, the slope of line is 0
Answer:
Step-by-step explanation:
Given
There are 52 cards in total
there are total of 13 pairs of same cards with each pair containing 4 cards
Probability of getting a pair or three of kind card=1-Probability of all three cards being different
Probability of selecting all three different cards can be find out by selecting a card from first 13 pairs and remaining 2 cards from remaining 12 pairs i.e.
![=\frac{52\times 48\times 44}{52\times 51\times 50}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B52%5Ctimes%2048%5Ctimes%2044%7D%7B52%5Ctimes%2051%5Ctimes%2050%7D)
for first card there are 52 options after choosing first card one pair is destroyed as we have to select different card .
For second card we have to select from remaining 12 pairs i.e. 48 cards and so on for third card.
Required Probability is ![=1-\frac{52\times 48\times 44}{52\times 51\times 50}](https://tex.z-dn.net/?f=%3D1-%5Cfrac%7B52%5Ctimes%2048%5Ctimes%2044%7D%7B52%5Ctimes%2051%5Ctimes%2050%7D)
![=\frac{22776}{132600}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B22776%7D%7B132600%7D)
Answer:
9

Hi .. im happy to help
answer is 0.033
Step-by-step explanation:
P = C(4,4)÷C(10,4)
P = 1 ÷ 30
![p = \frac{1 }{30}](https://tex.z-dn.net/?f=p%20%3D%20%20%5Cfrac%7B1%20%7D%7B30%7D%20)
p = 0.033
