If r+1=p-2=q-6=s+5=10, then what is the value of p+q+r+s?

Ineed if you could explain and give me the answer you! this needs done

You can find the constant of proportionality by finding the ratio of

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?
