Answer:
The probability that X and Y are both positive and that their sum is less or equal to 1 0.64.
Step-by-step explanation:
It is provided that the random variables <em>X</em> and <em>Y </em>follows a standard normal distribution.
That is,
It is also provided that the variables <em>X</em> and <em>Y </em>are statistically independent of each other.
Compute the probability that X and Y are both positive and that their sum is less or equal to 1 as follows:
The mean and standard deviation of <em>X</em> + <em>Y</em> are:
The probability is:
*Use the <em>z</em>-table.
Thus, the probability that X and Y are both positive and that their sum is less or equal to 1 0.64.
Yes that’s the answer so i hope appreciate the answer
Answer:
46.8
Step-by-step explanation:
1/3 of a cup = 3/9 of a cup. If you have 7/9 of a cup, the most 3/9ths that can fit in it is two 3/9ths, which equals 6/9. 6/9 < 7/9. Another latte would give you 9/9, and 9/9 > 7/9 so that's not possible. So two lattes can be made with 7/9 cups of milk.
Answer:
The answer is (4,-2)
Step-by-step explanation:
y=x-6
3x+2y=8
3x+2(x-6)=8
3x+2x-12=8 Combine like terms
3x+2x-12+12=8+12 add 12 to both sides then combine
5x=20→ x=4
then plug it in to y=x-6→y=4-6→y=-2
