M= y1-y2/x1-x2
m= 8/10
m= 4/5
Answer:
y=10x+0.4
Step-by-step explanation:
I did the test too.
Well how you doin corey!?
Im trying to find the answer too lol
Ariane feeds the kitten twice in the morning and twice in the evening. That's a total of 4 times. If each time she feeds them k grams, she feeds the kitten a total of
![\underbrace{k+k}_{\text{morning}}+\underbrace{k+k}_{\text{evening}} = 4k](https://tex.z-dn.net/?f=%20%5Cunderbrace%7Bk%2Bk%7D_%7B%5Ctext%7Bmorning%7D%7D%2B%5Cunderbrace%7Bk%2Bk%7D_%7B%5Ctext%7Bevening%7D%7D%20%3D%204k%20)
Similarly, she feeds the dog once in the morning and once in the evening. That's a total of two times. If each times she feeds the dog d grams of food, she feeds
grams of food to the dog.
So, the total is
grams of food each day.
Answer:
80/121
Step-by-step explanation:
For simplicity,
Probabilities of getting a red, a blue or a green in a single spin are, respectively, 4/11, 4/11 & 3/11.
Therefore, probabilities of getting 2 reds, 2 blues or 2 greens in 2 spins are, 16/121, 16/121 & 9/121 respectively.
Then, total probability of getting same colour both times would be 16/121 + 16/121 + 9/121 = 41/121.
Any other option would result in 2 different colours. Thus, the probability of getting two different colours in 2 spins = 1 - 41/121 = 80/121.
