Question

shown to the right is a scatter plot that indicates a relationship between the percentage of adult females in a country who are literate and the mortality of children under five (per thousand). also shown is a line that passes through or near the points. find a linear function that models the data by finding the slope - intercept form of the lines equation. use the function to make a prediction about child mortality based on the percentage of adult females in a country who are literate. using the indicated points on the graph of the line, find the slope - intercept form of the lines equation. use the percentage of adult females who are literate as the x - value. f(x)=−1.5x + 251 (simplify your answer. type an expression using x as the variable. use integers or decimals for any numbers in the expression.) use the function to predict the mortality rate of children under five in a country where 50% of adult females are literate. per thousand (type an integer or a decimal.)

Explanation:

Step1: Identify the function

The linear - function is given as $f(x)=-1.5x + 251$.

Step2: Substitute the value of x

We need to find the value of $f(x)$ when $x = 50$. Substitute $x = 50$ into the function: $f(50)=-1.5\times50+251$.

Step3: Perform the multiplication

$-1.5\times50=-75$. So, $f(50)=-75 + 251$.

Step4: Perform the addition

$-75+251 = 176$.

Answer:

176
