Answer: 114.8
Step-by-step explanation: first multiply 76 times 3.28 (249.28) then multiply 11 by 3.28 (364.08) and subtract to get your awnser
Answer:
34 boys
Step-by-step explanation:
72 students
G-19:B-17 Ratio
19 + 17 = 36
72/36 = 2
19 x 2 = 38
38 girls
17 x 2 = 34
34 boys
Answer:
58.6% of the variation in length (in cm) of new born boys and their weight (in kg) is explained by the line of best fit.
Step-by-step explanation:
Given the following :
R² value = 58.6% comparing the length (cm) of new born boys to their weight (kg)
The R² value is called the Coefficient of determination. It is obtained by taking the square of the correlation Coefficient (R). The value gives the proportion of Variation between the independent and dependent variables which is explained by regression line. In the scenario above, the R² value means that 58.6% of the variation in length in centimeter of new born boys and their weight (in kg) is explained by the line of best fit. While (100% - 58.6% = 41.4%) is due to other factors.
We can see that the graph touches 
without crossing the x-axis (i.e. it is a double solution), and then there's another zero at 
(this time it's a crossing zero, so a single solution).
This leads, up to multiple, to the polynomial
If we impose the passing through 
we have
So, the polynomial is
Finally, to solve 
, simply look at the graph, searching for the points, where the graph is below the x-axis. You can see that this happens only if 
, so that's the solution to your question.
4 out of 10 (or 4/10) is written as .4 as a decimal. This is because when you divide 4 by 10, you get .4
