NSC Mathematical Literacy Collecting data: 5.1 A survey published by the De

Question

5.1 A survey published by the Department of Education reported on the number of schools, learners and teachers in ordinary public schools and independent schools during 2013.

TABLE 3 in ANNEX D shows the number of learners, teachers and schools in South Africa.

NOTE: Some data have been omitted.

Use TABLE 3 to answer the questions that follow.

5.1.1 Which province had the second lowest number of learners? (2)

5.1.2 Determine the total number of teachers in South Africa for 2013. (3)

5.1.3 Calculate the percentage of schools found in KwaZulu-Natal. (3)

5.1.4 Use the formula below and determine the LSR for Gauteng.

Learner-School Ratio = Total number of learners
                           Total number of schools (3)

5.1.5 Use the provincial LTR to answer the following:

(a) Write down the modal ratio. (2)

(b) Arrange the ratios in descending order. (2)

(c) Determine the median ratio. (2)

5.1.6 Use the TSR to complete the bar graphs on the attached ANSWER SHEET. (0)

5.2 A school kept records of all the learners that arrived late for school. The Mathematical Literacy teacher noticed that the late arrival is influenced by the occurrence of rain.

The tree diagram below was drawn to show the outcomes and probability of late arrivals when the chance for rain is 25%.

Study the tree diagram and answer the questions that follow.

5.2.1 Write down the percentage of learners who arrive late if it does not rain. (2)

5.2.2 Write down the missing outcomes (a) and (b). (4)

5.2.3 Write down the probability (as a simplified common fraction) of randomly selecting a learner who arrived late for school on a rainy day. (3)

5.2.4 If the school has 1 562 learners, determine how many learners will not be late if the chance for rain is 25%. (3)

Which province had the second lowest number of learners?

Determine the total number of teachers in South Africa for 2013.

Calculate the percentage of schools found in KwaZulu-Natal.

Use the formula below and determine the LSR for Gauteng.

Write down the modal ratio.

Arrange the ratios in descending order.

Determine the median ratio.

Write down the percentage of learners who arrive late if it does not rain.

Write down the missing outcomes (a) and (b).

Write down the probability (as a simplified common fraction) of randomly selecting a learner who arrived late for school on a rainy day.

If the school has 1 562 learners, determine how many learners will not be late if the chance for rain is 25%.
