Answer:
Step-by-step explanation:
5, -4
5-4=1
5(-4)=-20
one expression using a variable for the unknown is... x = (3)(6/4)
Answer:
- P (blue or too big) = 11 / 12
Explanation:
A two way table permits to represent the situation clearly and find the answser is an easy way.
The two way table is that results from the given information is:
Initial information:
Blue Green Total
Fit well 4 1 ?
Too big ? ? ?
Total 5 7 12
Now by subtraction and addition you can fill the unknown fields:
Blue Green Total
Fit well 4 1 5
Too big 1 6 7
Total 5 7 12
Now, you can see that there are 5 blue and 7 too big shirts, but the total number of them is 5 + 7 - 1 (because one of the too big shirts is also blue).
Then, the number of shirts being blue or too big is 5 + 7 - 1 = 11.
And the probability is :
- P(blue or too big) = number of blue or too big / total number of shirts
- P (blue or too big) = 11 / 12 ← answer
You can also realize that there is only 1 green shirt that fits well, and that is the only option of not being blue of too big, so 1 /12 is the probability of not being blue or too big, and its complement (being blue or too big) is 1 - 1/12 = 11 / 12.
Hi!
We will solve this by simply multiplying both sides of the equation with 5, like this:
Hope this helps!
Answer:
y = -3/(x-4) - 2
Step-by-step explanation:
3*y(x) vertically stretches <em>y</em> by a factor 3
-y(x) reflects <em>y</em> over x-axis
y(x-4) translates <em>y</em> 4 units to the right
y(x) - 2 translates <em>y</em> 2 units down
Applied the transformations we get:
y(x) = 1/x → 3/x → -3/x → -3/(x-4) → -3/(x-4) - 2
