Answer:
x=8/3
y= -20/9
Step-by-step explanation:
4X + 3Y -4 =0
Linear egquations must in

so 4X + 3Y =4
THEN
3X + 9Y = - 12
next use calculator to solve it or you can use traditional way
Sum of the number and its of inverse equals 0.

Answer:
mean = 2.55
Standard deviation = 1.118
Step-by-step explanation:
Probability of babies who are boys
P = 0.51
Then we have q = 1-p
= 1-0.51
= 0.49
We have n = 5
We calculate the mean as:
np
= 0.51x5
= 2.55
Therefore mean = 2.55
The standard deviation
= √variance
= √npq
= √0.51x5x0.49
=√1.2495
= 1.118
So the answer would be (4n)1/3
