Step-by-step explanation:
The formula of a distance between two points:
We have the points
and
Substitute:
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:
soory idk
Step-by-step explanation:
X²+4=29
Collect like terms
X²=29-4
X²=25
Take the square root of both sides to find the value of X
√X² = √25
X = 5
X - 4 =5 - 4=1
