Answer:

Equations:

  • A number decreased by three is seven.
  • The quotient of a number and six is two.
  • x – 5 = 21

Expressions:

  • 9 + n
  • The product of a number and eleven

Step-by-step explanation:

Required

Determine which is an expression and which is an equation

To start with, we analyse each of the options one after the other

<em></em>

(a): A number decreased by three is seven.

Let the number be n

<em></em>

<em>So, when n is increased by 3, the result  is 7. </em>

This statement can be represented as:

<em></em>n + 3 = 7<em></em>

<em></em>

<em>The above is an equation because it has an = sign</em>

(b) 9 + n

This is not an equation <em>because it has no = sign.</em>

<em>Hence, it is an expression.</em>

(c) The product of a number and eleven

Let the number be n

<em></em>

<em>n multiplied by 11 is represented as:</em>

<em></em>n * 11<em></em>

<em></em>

This is not an equation <em>because it has no = sign.</em>

<em>Hence, it is an expression.</em>

(d) The quotient of a number and six is two.

Let the number be n

<em></em>

<em>So, the quotient of n and 6, is 2. </em>

This statement can be represented as:

\frac{n}{6} = 2

<em></em>

<em>The above is an equation because it has an = sign</em>

(e) x – 5 = 21

<em>The above is an equation because it has an = sign</em>

pickupchik [31]
3 out of 25 = 12 out of 100
3 out of 50 = 6 out of 100
2 out of 25 = 8 out of 100
12 + 6 + 8 = 26
100 - 26 = 74%

Inga [223]

Answer:

Option a is right

Step-by-step explanation:

Given that as part of a research project on student debt at TWU, a researcher interviewed a sample of 35 students that were chosen at random concerning their monthly credit card balance.

Sample average = 2573

Variance = 4252

Sample size = 35

STd deviation of X = \sqrt{4252} \\=65.21

Score of student selected at random X=1700

Corresponding Z score = \frac{1700-2573}{65.201} \\=-13.38

Rounding of we get Z score = -13.4

option a is right
