Question:

5. In a class of 78 students 41 are taking French, 22 are taking Swahili. Of the students taking French or Swahili, 9 are taking both courses. How many students are not enrolled in either course? A. 6 B. 15 C. 24 D. 33 E. 54

Ozivefueshe D.
Answer:

Answer: C In order to answer this question, add the number of students taking French and Swahili (41+22=63). Because 9 of those students are taking both classes, subtract 9 from that total to account for these students represented in each class (63-9=54). Now that you know how many students are taking a language class, you can subtract from the total number of students (78) from the total number of students taking a language class (54). Your calculation should give you 24.

Answer:

10 per 1,000 The crude mortality rate it the death rate that is calculated using all deaths as the numerator and the total population as the denominator. Therefore Crude mortality rate = total deaths/total population = 1000/100,000 = 10 per 1,000 *Tip*: Don't get caught up with frivolous information. Crude mortality rate means just that: the mortality rate as the most basic level.

Answer:

A. Concrete Operational Stage Children at the concrete operational stage of development begin to reason more logically, but their thinking is still very rigid. They tend to struggle with abstract and hypothetical concepts. Kids at this stage start to understand that their thoughts are unique to them and that not everyone else necessarily shares their ideas, emotions, and opinions.
