Answer:
yes
Step-by-step explanation:
To determine if the point lies on the line substitute the coordinates into the left side of the equation and if equal to the right side then the point lies on the line
- 3 + (4 × 4) = - 3 + 16 = 13 = right side
Hence (- 3, 4) lies on the line x + 4y = 13
Answer:
simplify: 14/40
not simplify: 7/20
I don't know if it's right but i'm trying to help :)
Not direct answer but
this is how I think
radius = 4 so AC is also 4
You can find with this
2π ( 4 ) ( 51°/360°) = Answer
Actually I am lazy to calculate (◔‿◔)
Answer:
I pretty sure its B.
Step-by-step explanation:
Answer:
a) 0.3889
b) 0.5
c) 0.8333
d) The mean is 250 and the standard deviation is 51.96.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability of finding a value of X higher than x is:

The probability of finding a value of X between c and d is:

The mean and the standard deviation are, respectively:


A random variable follows the continuous uniform distribution between 160 and 340.
This means that 
a)

b)

c)

d)


The mean is 250 and the standard deviation is 51.96.
