Answer:
A.
Step-by-step explanation:
Twust me n' dwont doubt me
A is for apple
And cause A looks like ABC
DWUHHH
X = larger number, y = smaller number
x + y = 38...because the sum of the numbers is 38
x = 2y - 10....larger one is 10 less then twice the smaller
now we will sub in 2y - 10 for x back into the first equation
x + y = 38
2y - 10 + y = 38
3y - 10 = 38...add 10 to both sides
3y = 38 + 10
3y = 48 ...divide both sides by 3
y = 48/3
y = 16
now sub 16 in for y back into either of the original equations and find x
x = 2y - 10
x = 2(16) - 10
x = 32 - 10
x = 22
so ur numbers are 16 and 22
The range is the simplest measure of variation . It is the difference between the biggest and smallest random variable.
Range= maximum value - minimum value
ex. Therefore in the range of these variables: (2,4,4,7} you would do 7 minus 2
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:
