Answer:
54
Step-by-step explanation:
27x2= 54
Answer:
a. when x=1 so substitute 1 to any X in the given equation.
y=-3(1)+2.5
y=-3+2.5
y=-0.5
b.when x is -1.5 so substitute -1.5 to any x in the equation
y=-3(-1.5)+2.5
y=-4.5+2.5
y=-2
Answer:
the last one
3x-y=1
-2x+y=-4

Answer:
SO we get the probability of NOT choosing a blue pant as
or ![\frac{6}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B10%7D)
Step-by-step explanation:
So we have:
No. of Blue pants = 4
No. of Black pants= 2
No. of White pants= 1
No. of Tan pants = 3
Total no. of pants = 4 + 2 + 1 +3 = 10
Now we have the total number of pants. Now we have two ways to find out the answer we can either calculate the sum of the probabilities of choosing all pants other than blue. Or we can calculate the probability of choosing a blue pant.
So the probability of choosing a blue pair of pants = ![\frac{4}{10} = \frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B10%7D%20%3D%20%5Cfrac%7B2%7D%7B5%7D)
So now we know the probability of choosing a blue pair of pants. Now what is the probability of choosing all pants? it is equal to 10/10
We subtract this number from the prob. of blue pants = ![\frac{10}{10} - \frac{2}{5} = \frac{5}{5} - \frac{2}{5} = \frac{5-2}{5} = \frac{3}{5} \\](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B10%7D%20-%20%5Cfrac%7B2%7D%7B5%7D%20%3D%20%5Cfrac%7B5%7D%7B5%7D%20-%20%5Cfrac%7B2%7D%7B5%7D%20%3D%20%5Cfrac%7B5-2%7D%7B5%7D%20%3D%20%5Cfrac%7B3%7D%7B5%7D%20%5C%5C)
SO we get the probability of NOT choosing a blue pant as
or ![\frac{6}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B10%7D)
