Percent means parts out of 100
30% =30/100=0.30
'of' means multiply
30% of 32.95 means
0.3 times 32.95=9.885
30% of 32.95=9.885
Answer: 16 red velvet cupcakes.
Step-by-step explanation:
To solve this problem you can apply the following proccedure:
- Let's call the number of red velvet cupcakes in a box that has 24 chocolate cupcakes: 
- Based on the information given in the problem, you can set up the following proportion and Solve for <em>:</em>
There are 16 red velvet cupcakes in a box that has 24 chocolate cupcakes.
Independent variable is the predictor variable which is the height and dependent variable is the response variable which is weight in this scenario.
The square of correlation coefficient gives the coefficient of determination. It is denoted by R² (R squared).
We are given:
R = 0.75
So,
R² = 0.75²
R² = 0.5625
R² = 56.25 %
The coefficient of determination tells how much of the trend of dependent data can be explained by the independent data using the linear regression model. So in the given case, Height can explain 56.25% of the trend in the weight.
