Answer:
Step-by-step explanation:3,9,27,81 because this is multiplication
Answer:
26 Members Voted
Step-by-step explanation:
50 % is 50/100
Voted = 
It's 5 over 9 because you start off with 10 cards (6 roses 4 daisies) then you pick a rose. Then it become's 5 over 9 since there are only 5 roses left and 9 total cards left.
Answer:
option c is the correct answer
Step-by-step explanation:
∠YXZ+117°=180°
∠YXZ=180°-117°
∠YXZ=63°
63°+36°+∠YZX=180°(sum of angles is 180)
99°+∠YZX=180
∠YZX=180-99
∠YZX=81
Answer:
90% CI expects to capture u 90% of time
(a) This means 0.9 * 1000 = 900 intervals will capture u
(b) Here we treat CI as binomial random variable, having probability 0.9 for success
n = 1000
p = 0.9
For this case, applying normal approximation to binomial, we get:
mean = n*p= 900
variance = n*p*(1-p) = 90
std dev = 9.4868
We want to Find : P(890 <= X <= 910) = P( 889.5 < X < 910.5) (integer continuity correction)
We convert to standard normal form, Z ~ N(0,1) by z1 = (x1 - u )/s
so z1 = (889.5 - 900 )/9.4868 = -1.11
so z2 = (910.5 - 900 )/9.4868 = 1.11
P( 889.5 < X < 910.5) = P(z1 < Z < z2) = P( Z < 1.11) - P(Z < -1.11)
= 0.8665 - 0.1335
= 0.733
