Answer:

4800

Step-by-step explanation:

Given the function

y = 75 × 4^{x}

x is the number of 15 year periods

45 years has 3 15 year periods , thus x = 3

Substitute x = 3 into the function and solve for y

y = 75 × 4³ = 75 × 64 = 4800

There will be 4800 foxes after 45 years

The graph shows a relationship between the size of 18 households and the average amount of time, in hours, each member of the ho
topjm [15]

Answer:

Option (D)

Step-by-step explanation:

Equation to represent the household expenditure per week will be in the form of,

y = mx + b

Where m = slope of the line

b = y-intercept

From the graph attached,

Since, line of best fit touches the positive side of the y-axis, y-intercept will be positive.

Since, y-values on the graph are decreasing with the increase in the x-values,

Slope of the graph will be negative.

[Slope = \frac{\text{Rise}}{\text{Run}}, Since rise of the line is negative and run is positive, slope will be negative]

By these properties equation of the linear graph will be,

y = -0.34x + 5.19

Option (D) will be the correct option.
