Answer:
B yes
Step-by-step explanation:
The length written in scientific notation is 85 x 10^-6
Answer:
a) P(x=5) = 0.2456
b) P(x≥6) = 0.3526
c) P(x<4) = 0.1887
Step-by-step explanation:
We can model this as a binomial experiment, with sample size n=10 and p=0.49.
To calculate the probability of having k subjects with very little confidence in the sample of 10, we solve:
a) We have to calculate P(x=5).
For a binomial variable with n=10 and p=0.49, this can be calculated as:
b) We have to calculate P(x≥6). This can be calculated as:
c) We have to calculate P(x<4). That is:
Answer:
93
Step-by-step explanation:
if you do 31 times 1 + 31 times 2, you get your answer
(i think that's right if not i'm sorry)
Answer: 244 degrees
==================================
The formula we can use is
L = (a/360)*2*pi*r
where,
L = arc length
a = central angle in degrees
r = radius
-----------
In this case, r = 34 and L = 145. We want to find the angle 'a'.
L = (a/360)*2*pi*r
145 = (a/360)*2*pi*34
145 = (a/360)*68pi
145*360 = a*68pi
52200 = a*68pi
a*68pi = 52200
a = 52200/(68pi)
a = 244.3496
a = 244
