Answer:

0.5% per year

24.2%

Step-by-step explanation:

Calculate the average annual growth rate of first-year college females reporting no religious affiliation

Proportions of females by year:

1980 = 6.2%

1990 = 10.8%

2000 = 13.6%

2012 = 21.7%

Average annual increase:

Percentage increase from 1980 - 2012:

2012% - 1980% = ( 21.7% - 6.2%) = 15.5% rise over [(2012 - 1980)] = 32 years

15.5 % / 32 years = 0.484375% / year = 0.5%/year

b. Predict the percentage of first-year college females who will assert no religious affiliation in 2030,

Assuming an average growth of 0.484375% / year

(2030 - 1980) = 50 years

Thus in 2030; ( 50 years × 0.484375%/year) = 24.218% will claim no religious association.

=24.2% (rounded to the nearest tenth)

Answer:

3.5 $m^2$

Step-by-step explanation:

For a shape that is half a circle, use the formula: A = $\frac{1}{2}$ π $r^2$

Calculate the radius, which is half of the diameter: r = d/2 = 3/2 = 1.5

Insert r = 1.5 into the formula.

A = $\frac{1}{2}$ π $1.5^2$

A = $\frac{1}{2}$ (3.14) $1.5^2$

Calculate the result with your calculator and round it off.

The final answer is 3.5

Thus, the most suitable answer is b..42.Step-by-step reasoning:Prior concepts include an explanation of Analysis of variance (ANOVA), which is employed to assess variances among group averages within a sample. The sum of squares constitutes the total squared variation where variation is defined as the disparity between each value and the grand mean. The correlation coefficient evaluates the strength of the correlation between two variable movements, noted as r, with values bounded between -1 and 1. In conducting multiple regression analysis, we seek to ascertain the relationship among multiple independent (predictor) variables and a dependent (criterion) variable.Solution:Assuming the presence of $k$ independent variables and $j=1,\dots,j$ individuals, we can articulate various formulas of variation: We also possess a characteristic identified as $SST=SS_{regression}+SS_{error}$ . The model's degrees of freedom in this circumstance is represented by $df_{model}=df_{regression}=k=2$ , with k =2 indicative of the variable count. The error's degrees of freedom is articulated by $df_{error}=N-k-1=30-2-1=27$ . The coefficient of determination in multiple regression is illustrated as: thus, the answer is b..42.
