<u>Linear</u> expression is usually an expression of 1st degree.

A. The product of a number and seven $=7\cdot n=7n$

Correct, linear

B. The sum of three consecutive numbers.

Let the smallest number be n, the next number is n + 1 and the last number is n + 2. Then their sum is

$n+(n+1)+(n+2)$

Correct, linear

C. The square of a number times three.

Let the number be n, then its square is $n^2$ and the square of a number times three is

$n^2\cdot 3=3n^2$

Correct, nonlinear

D. Twice the sum of a number and 8.

If the number is n, then the sum of the number anf 8 is n + 8. Twice the sum is

$2\cdot (n+8)=2(n+8)$

Incorrect, linear

E. The cube of a number divided by two.

If the number is n, then its cube is $n^3.$ The cube of the number divided by 3 is

$n^3\div 3$

Correct, nonlinear

kupik [55]

Answer:

(78, 80)

Step-by-step explanation:

Given a normal distribution :

Mean = 79 seconds

Standard deviation = 0.5 seconds

Using the empirical rule :

95% of her finishing times :

According to the empirical rule, 95% represents 2 standard deviations from the mean that is ± 2 standard deviations from the mean score or value.

Hence ;

The interval will be defined as ;

Mean ± 2(standard deviation)

79 ± 2(0.5)

79 ± 1

(79 - 1) ; (79 + 1)

78 ; 80
