Question

the stacked line chart shows the numbers of college degrees awarded to males and females since 1970. complete parts (a) through (d).

a. estimate the numbers of college degrees awarded to males and to females (separately) in 2020.

the number of college degrees awarded to males in 2020 was
the number of college degrees awarded to females in 2020 was

Explanation:

Read the male data value for 2020

Using the Stacked Line Chart Interpretation knowledge point

• Locate the year 2020 on the horizontal axis.
• Find the height of the lower shaded region (cyan, representing Male).
• The top boundary of the cyan region at 2020 aligns with the grid line at \(8\).
• Since the vertical axis represents "Number of degrees (hundred thousands)", the value is \(8\) hundred thousand, which is \(800,000\).

Read the total data value for 2020

Using the Stacked Line Chart Interpretation knowledge point

• Locate the year 2020 on the horizontal axis.
• Find the top boundary of the upper shaded region (purple, representing Female).
• The top boundary of the purple region at 2020 aligns with the grid line at \(20\).
• This represents the combined total of degrees awarded to both males and females: \(20\) hundred thousand, which is \(2,000,000\).

Calculate the female data value for 2020

Using the Stacked Line Chart Interpretation knowledge point

• Subtract the male value from the total value to find the female value.

$$ \text{Female Value} = \text{Total Value} - \text{Male Value} $$

$$ \text{Female Value} = 20 - 8 = 12\text{ hundred thousands} $$

• This corresponds to \(1,200,000\) degrees.
