Answer:
four years old
Explanation:
Roberta and her peers are most likely four years old. Most children tend to recognize and label stereotypical gender groups at about 2 years of age and at 3 years they are able to recognize their own gender and at age 3 to 4 years they use gender labels quite consistently. However, at age 5 and 6 children become rigid about gender stereotypes and preferences. Roberta and her classmates are likely 4 years of age.
Mayan number system is a vigesimal system- that means with a base of 20:
the correct answer is: 20, the Mayan number system is based on the number 20.
This means that a number like 360 is expressed with "18 times 20".
Scientists suggest that number systems based on 10 are inspired by the number of fingers, and number systems based on 20 could be based on fingers counted twice: after the number 10, hands would be turned upside-down.

Answer:
Family life is changing. Two-parent households are on the decline in the United States as divorce, remarriage and cohabitation are on the rise. And families are smaller now, both due to the growth of single-parent households and the drop in fertility. Not only are Americans having fewer children, but the circumstances surrounding parenthood have changed. While in the early 1960s babies typically arrived within a marriage, today fully four-in-ten births occur to women who are single or living with a non-marital partner. At the same time that family structures have transformed, so has the role of mothers in the workplace – and in the home. As more moms have entered the labor force, more have become breadwinners – in many cases, primary breadwinners – in their families.
As a result of these changes, there is no longer one dominant family form in the U.S. Parents today are raising their children against a backdrop of increasingly diverse and, for many, constantly evolving family forms. By contrast, in 1960, the height of the post-World War II baby boom, there was one dominant family form. At that time 73% of all children were living in a family with two married parents in their first marriage. By 1980, 61% of children were living in this type of family, and today less than half (46%) are. The declining share of children living in what is often deemed a “traditional” family has been largely supplanted by the rising shares of children living with single or cohabiting parents.
