Answer:
below given!
Step-by-step explanation:
1) mean = (7.4 + 5.8 + 7.3 + 7 + 8.9 + 9.4 + 8.3 + 9.3 + 6.9 + 7.5 + 9 + 5.8 + 5.5 + 8.6 + 9.3 +3.8) / 16
mean = 7.47
X is 66 degrees, you just subtract 24 to 90 and it gives you 66.
The first one is 21.93 rounded up to 22.
Answer:
1. 15%
2. 85%
Step-by-step explanation:
The graph is 100 units,
the shaded part is 15 units,
so it is 15%,
if it is 15% than the unshaded part is 85%.
Answer:
no rain today = 35%
Step-by-step explanation:
In probability, the Complement Rule states that the sum of the probability of an event and its complement must = 1
i.e
P( Event) + P (Complement) = 1
In this sense, we can think of the complement of an event as the "not-event". I.e the event does not happen.
In our case, the event = "rain today",
hence the complement will be = "not rain today" (i.e no rain today)
using the formula above, we are given that P(rain today) = 65% = 0.65
hence
0.65 + P(Complement) = 1
P(Complement) = 1 - 0.65 = 0.35 = 35%
