Consider the regression through the origin model y = bx Assume that there are n pairs of observations of the response and the explanatory variables, and that these observations are indexed by i. Derive the least-squares estimator for the slope parameter b in this model.

A couple where both the man and woman are albino decided to have children. Remember that albinism is inherited as a rare autosomal recessive trait. To their surprise their first child had normal skin pigmentation. They eventually have two more children and they also have norma...

Thank you very much, I dont remember learning it like this but this certainly does help alot and this makes it easier to understand. Once again, thank you

My original question: In a diploid organism with 2n=8, what is the probability that one of its gametes will contain only paternally derived chromosomes (ie, not a mixture of paternal and maternally derived chromosomes)? PsyDAG replied: Since 4 of the 8 are paternal, 4/8 * 3/7 ...

**Science**

can you please explain how you got those numbers.

**Science**

for number two you gave to calculate the probability of only 3 male offsprings being born and the probability of at least one being black.

Black coat colour in Labrador Retrievers is produced by the dominant B allele. Brown labs are homozygous recessive (bb). Duke, a black male, whose mother was brown, is mated with Shadow, a black female, who in a previous mating with another father produced brown offspring. Wha...

A light year is the distance it takes a beam of light to travel in a year. The speed of light is 2.99 x 10^8 m/s. Distance from sun to Earth: 150 000 000 Km *remember to change km to m use equation: t=d/v t=150 000 000 000m/2.99 x 10^8 m/s t=501sec = 8.35 min **I rounded the d...

For which real values of x do the following vectors form a linearly dependent set in R3? v1= (x, -1/9, -1/9) v2= (-1/9, x, -1/9) v3= (-1/9, -1/9, x)

**physics**

In the problem, the mass isn't known though, you know that the one car is identical to the other though. i end up getting, 90km/h=M1*V What do I do after that?

**physics**

Thank you that was bothering me for so long.

**physics**

The question is: two identical cars hit each other and lock bumpers. If a car moving with a speed of 90km/h appraoches a stationary car, what is the speed immediately after coupling cars.

Hi, i really need help with this question. Two identical cars hit each other and lock bumpers. A car moving with a speed of 90 km/h approaches a stationary car
