How do you interpret expressions that represent a quantity in terms of its context?

natali 33 [55]

Interpret parts of an expression, such as terms, factors, and coefficients. Interpret complicated expressions by viewing one or more of their parts as a single entity. For example, interpret P(1+r)n as the product of P and a factor not depending on P. Use the structure of an expression to identify ways to rewrite it.

If the mean is 4, what is the missing number of the data set: 3, 4, ___, 7, 2, 1.

kodGreya [7K]

Answer:

Step-by-step explanation:

Let the missing number of the data be x.

$\because mean = \frac{3 + 4 + x + 7 + 2 + 1}{6} \\ \\ \therefore 4 = \frac{17 + x }{6} \\ \\ \therefore 4 \times 6 = 17 + x \\ \\ \therefore 24 - 17 = x \\ \\\therefore x = 7$

Thus, the missing number of the data is 7.

Kamila [148]

Answer:

a) 8 groups

b) 5 boys per group and 7 girls per group

Step-by-step explanation:

School trip has 40 boys and 56 girls.

We solve the above question using the Greatest Common Factor Method

We find the factors of 40 and 56

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40

The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56

Then the greatest common factor is 8.

a) What is the greatest number of groups that can be formed?

The greatest number of groups that can be formed is 8 groups

b)How many boys and how many girls will be in each group?

For boys.

The number of boys in each group is calculated as:

40 boys/8 groups = 5 boys per group

For girls

For 56 boys.

The number of boys in each grouo is calculated as:

56 girls /8 groups = 7 girls per group
