The four interior angles of a quadrilateral always add to 360<span>°, so the answer is 98</span>
AC = (-5)(-3)
sum = -8
x^2 - 5x - 3x + 15
x(x-5)-3(x-5)
(x-3) (x-5)
x=3 x=5
The answer would be
3 5/12, because you would make 3 2/3 into 3 8/12 for the greatest common factor and make 1/4 into 3/12 when you subtract 3/12 - 3 8/12 you get 3 5/12.
The answer is 90 :D if you get a chance make this the brainliest answer, thanks!
Based on the information given, it should be noted that the mean and standard deviation of Y will be 0.4899 and 0.699 respectively.
<h3>Calculating the mean.</h3>
Based on the information given, it should be noted that the probability distribution for y will be:
Y 0 1. 2
Probability 0.63. 0.25. 0.12
The mean of Y will be:
= (0 × 0.63) + (1 × 0.25) + (2 × 0.12)
= 0 + 0.25 + 0.25
= 0.49
The variance will be 0.4899. Therefore, the standard deviation will be:
= ✓0.4899
= 0.699
