The reaction times form a straight line with gradient of 60/140 = 3/7 m/kph
Reaction time at 130 kph = 3/7 x 130 = 390/7 = 56 m to nearest whole number
Answer:
No Solution
Step-by-step explanation:
Assuming the lines are absolute value you must get rid of the other numbers first so:
5 |x+7| + 14 = 8
5 |x+7| = -6
and since absolute values can't equal a negative the answer is NO SOLUTION
Answer:
(4, 6)
Step-by-step explanation:
90 degree goes counterclockwise so
(6,-4) becomes( 4, 6)
(x,y) rotation 90 or -270 is (-y,x)
A- 4/6, B- 3/6
If both events happen, the probability is A*B= 4/6 * 3/6 = 12/36= 1/3
P(AnB)= 1/3
Answer:
40
Step-by-step explanation:
5*4*2
