343 hope this helps have a good day
<span>At the animal shelter there are 56 more dogs than cats. If the total number of animals is 200 how many of each type are in the shelter?
dogs + cats = 200 eq I
</span>dogs = 56 + cats eq II
replace dogs in eq I
(56 + cats) + cats = 200 eq with one variable
56 + 2c = 200
2c = 200 - 56
2c = 144 /divided 2
<u>cats= 72</u>
dogs = 56 + cats = 56 + 72 = 128
<u>dogs = 126</u>
Answer:
It is not reasonable to use the line of best fit to make predictions from the data.
Explanation:
A correlation coefficient of r = 0.15 means that the goodness of fit for the data from linear regression analysis is
r² = 0.15² = 0.0225.
When r²=1, it means that correlation between the dependent and independent variable is perfect, and the dependent variable can be predicted reliably.
When r²=0, it means that there is absolutely no correlation between the dependent and independent variable.
When r²>0.9, it means that reasonable correlation exists between the dependent and independent variable.
A value of r²=0.0225 is extremely low, therefore it is not reasonable to use the line of best fit to make predictions.
Answer:91
Step-by-step explanation:
If the best grade is 100,91 is it.
