The number of pennies is an illustration of pattern and sequence.

The number of pennies in the nth square is 2^{n-1

From the complete question, we have the following parameters

f(1) =1

f(2) =2

f(3) =4

f(4) =8

Rewrite the functions as follows:

f(1) = 2^0

f(2) = 2^1

f(3) = 2^2

f(4) = 2^3

Express 3 as 4 - 1

f(4) = 2^{4-1

Replace 4 with n

f(n) = 2^{n-1

Hence, the number of pennies in the nth square is 2^{n-1

A college job placement office collected data about students’ GPAs and the salaries they earned in their first jobs after gradua
frez [133]

Answer:

X is the GPA

Y is the Salary

Standard deviation of X is 0.4

Standard deviation of Y is 8500

E(X)=2.9

E(Y)=47200

We are given that The correlation between the two variables was r = 0.72

a)y = a+bx

b = \frac{\sum(x_i-\bar{x})(y_i-\bar{y})}{\sum(x_i-\bar{x})^2} = \frac{r \times \sqrt{var(X) \times Var(Y)}}{Var(X)} =  \frac{0.72 \times \sqrt{0.4^2 \times 8500^2}}{0.4^2} = 15300

a=y-bx = 47200-(15300 \times 29) = 2830

So, slope =  15300

Intercept =  2830

So, equation : y = 2830+15300x

b) Your brother just graduated from that college with a GPA of 3.30. He tells you that based on this model the residual for his pay is -$1880. What salary is he earning?

y = 2830+15300 \times 3.3 = 53320

Observed salary = Residual + predicted = -1860+53320 = 51440

c)) What proportion of the variation in salaries is explained by variation in GPA?

The proportion of the variation in salaries is explained by variation in GPA = r^2 = (0.72)^2 =0.5184

What is the area of the figure? Explain the steps you take
finlep [7]

Answer:

7.2 in² or 7.2 inches squared

Step-by-step explanation:

Area is a measure of how much space there is on a flat surface.

To find the area, just multiply the length and width of the figure.

2 × 3.6 is 7.2

When you find the area, you have to square it.

So, the answer is 7.2 in², or 7.2 inches squared
