Answer:
1/9
Step-by-step explanation:
Of the 36 possible sums, 4 of them are 9. The probability is 4/36 = 1/9.
_____
Comment on these dice
Interestingly, the probability of any given sum is the same as it is with "normal" dice.
Answer:
x²-10×+25=16
ײ-10×=16-25
×(×-10)=-9
but if your question is rather 2x-10×+25=16
then here goes the answers
2x-10×+25=16
-8×=16-25
-8×=-9
×=9/8
×=1¹/8
6x-4>8-2x
Add 2x on each side
8x-4>8
8x>12
x>12/8
x>3/2
The answer is B
Answer:
When x = 8.4 and y = .8 then 4x + 8y = 40
Step-by-step explanation:
4x + 8y = 40
y = .8
Let's solve for x by substituting .8 for y (since y is given)
4x + 8(.8) = 40
4x + 6.4 = 40 Subtract 6.4 from both sides.
4x + 6.4 - 6.4 = 40 - 6.4
4x = 33.6 Divide each side by 4
4x/4 = 33.6/4 4 cancels on the left because 4/4 = 1
x = 33.6/4
x = 8.4
So when x = 8.4 and y = .8 then 4x + 8y = 40
Answer:
(1;3)
Step-by-step explanation:
midpoint=(x1+x2;y1+y2)÷2
=(-2+4;-3+9)÷2
=(2;6)÷2
=(1;3)
