Step-by-step explanation:
Given
( 6x² - x + 8 ) - ( x² + 2)
= 6x² - x + 8 - x² - 2
= 5x² - x + 6
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.
The perimeter of the rectangle is given by the formulae,
Where
is the length and
is the width of the rectangle.
Now let us substitute into the formula,
The above expression corresponds to option
F.
Now when we expand the bracket, we obtain,
This also corresponds to option A.
The correct answers are
The answer is 11. 0.22 x 50 is 11.
