R = 8 since 8 times 10 = 80
Answer:
.
Step-by-step explanation:
It is given that a die is rolled one time. So,
Sample space : 
Number is greater than 3 : 
Number is odd : 
Number greater than 3 and an odd number : 
It is conclude that,
The probability of getting a number greater than 3 and an odd number is
Therefore, the required probability is .
2^6 is the answer. Multiply the rules because it’s a rule
Looking for the height, if trapezoid area equals (a+b)/2 x h then h = 2A/(a+b)
so h = 2(30)/(4.8+5.2) = 6
Answer:
y = -1/2x +1/2
Step-by-step explanation:
Point B is 4 up and 2 over from point A. So, the midpoint will be 4/2 = 2 up and 2/2 = 1 over, at (1, 0).
The ratio of rise to run between A and B is ...
m = rise/run = 4/2 = 2
The perpendicular line will have a slope that is the opposite reciprocal of this, -1/2.
Then the point-slope equation for the perpendicular bisector is ...
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y -0 = -1/2(x -1) . . . .line with slope -1/2 through point (1, 0)
y = -1/2x +1/2 . . . . simplified to slope-intercept form
