Answer:
y = 5x - 2
Step-by-step explanation:
Gradient is also known as slope . The gradient of a line is represented by the equation
Slope (m) = y - y1/ x - x1
Where m = 5 , x1= 1 and y1 = 3
Imputing the values into the equation
m = y - y1/ x - x1
5 = y - 3 /x - 1
Cross multiply, we have
y -3 = 5(x - 1)
Expand
y-3 = 5x - 5
Add 3 to both sides
y-3+3 = 5x - 5 +3
y = 5x - 2

Answer:
a)
P(X = 0) = 5/10
P(X = 5) = 3/10
P(X = 10) = 2/10
b)
E = 0·5/10 + 5·3/10 + 10·2/10 = 3.5
V = 0^2·5/10 + 5^2·3/10 + 10^2·2/10 - 3.5^2 = 15.25

Answer:
1/2
Step-by-step explanation:
Since the recessive gene is carried in the x chromosome and a father can only pass it to a daughter, the father doesn't have the disease nor carries it.
The mother carries the recessive gene because her father passed her his conditioned gene (only having one x chromosome), while her mother gave her a normal one so she can have normal vision.
The chance of having a boy or a girl is 1/2 and the chance of this baby of having both recessive gene is null because in order to have a girl that is color blind both her x chromosomes must have the recessive gene, but the father can't pass it since he doesn't carries it. Therefore the combined probability is 1/2*(1-0) = 1/2.
