Answer:
The first option (0.80)
Step-by-step explanation:
First, we need to find all the outcomes which meet the criteria, and in this case there are 1,3,5,6,7,8,9,10. In total we have 8 outcomes that meet our criteria out of 10 outcomes,, therefore the probability of the outcome to be greater than 4 or an odd number equals...
8 / 10 = 0.8
Answer:
-4x^2 – 2xy + 2y^2 + 9
Step-by-step explanation:
First, perform the indicated multiplications: Multiply each 7x^2, -3xy and -3^2 by -1:
If this is done properly, we get: -7x^2 + 3xy + 9
Now rewrite (3x^2 – 5xy + 2y^2)-(7x^2 – 3xy - 3^2) as
3x^2 – 5xy + 2y^2 - 7x^2 + 3xy + 9)
Combining the x^2 terms, we get:
-4x^2 – 5xy + 2y^2 + 3xy + 9.
Combining the xy terms, we get:
-4x^2 – 2xy + 2y^2 + 9
This is the final answer (sum), since none of these four terms can be combined.
Let the width be w. Therefore we can right the length as w+2=l. We know the formula for perimeter is 2w + 2l = P. We can fill this formula in to help solve this problem with the pieces we have.
2w+2(w+2)=24
2w+2w+4=24
4w=20
w=5
So, we now know the width of the room. Next, lets plug that into the perimeter equation again and solve for the length now.
2(5) + 2l = 24
10 + 2l = 24
2l = 14
l=7
So the width is 5m and the length is 7m.
