Well the answer is d I think lol I haven't done this equation in a while
Answer:
7.5
Step-by-step explanation:
3x+4y=36y=-1/2+8=
Answer:
See explanation
Step-by-step explanation:
A dog owner observes that from birth to age 14 weeks, the puppy’s weight can be modelled by the equation
In this equation,
- number 365 represents the initial weight of puppy;
- number 1.23 can be rewritten as 1+0.23, where 0.23 (or 23%) is the rate of weight increase.
When w=4,000, then
This means that puppy will weight 4,000 grams nearly at the middle between 11th week and 12th week.
Answer:
20x-21y+14

Answer:
r = -0.83
strong negative correlation
r = -0.08
weak negative correlation
r = 0.96
strong positive correlation
r = 0.06
weak positive correlation
Step-by-step explanation:
In this question, what we are expected to do is to match the values of the correlation given with the type of correlation in which the values are.
When we talk of correlation, we are simply referring to the extent of agreement between the values in the data field.
Correlation has a value between -1 and +1, meaning it could be negative or positive.
Values closer to the extremes i.e (-1 or +1) indicates strong correlation while values farther away, i.e closer to zero indicates a weak relationship.
Let’s answer the questions specifically now:
r = -0.83
This is closer to -1 and it indicates a strong negative correlation
r = -0.08
This indicates a weak negative correlation as it is closer to zero and farther away form -1
r = 0.96
This indicates a strong positive correlation
r = 0.06
This indicates a weak positive correlation
