36 equally-likely outcome: (1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1),(6,2), (6,3), (6,4), (6,5), (6,6)
Solution:
Outcomes with first number being old number and second being even number: (1,2), (1,4), (1,6), (3,2), (3,4), (3,6), (5,2), (5,4), (5,6) = 9 outcomes
P(old,even) = 9/36 =1/4 = 0.25
Answer:
-24degC
Step-by-step explanation:
-6degC dropping by 2degC leads to -8degC (2degC colder, higher value negative numbers are colder as negative numbers increase in the opposite direction of positives)
so next -8degC rising by 3degC which is 3degC hotter(less negative) will give -5degC
the finap drop by 9degC makes the final temperature -5 -19 = -24degC(similar reasoning)
if you want a more straightforward method to doing these sorts of questions, just take temperature rise : add the value it rose by and temperature fall/drop: subtract the value it dropped/falled by.
Answer:
18.9
Step-by-step explanation:
The formula after being set up is 20 cos 19. After solving, that is the answer.
Step-by-step explanation:
20/h = 8/14
Cross multiply
20 × 14 = h × 8
280 = 8h
Isolate the variable (h) by dividing by 8 on both sides
35 = h
