Suppose an automobile manufacturer designed a radically new lightweight engine and wants to recommend the grade of gasoline that
MissTica

Answer:

4.07

Step-by-step explanation:

The sample size is 12. The number of treatments is 4. Thus, the degrees of freedom associated with the sum of square error is 8 which is sample size minus number of treatments. The degree of freedom is 3 which is number of treatments minus 1. The theoretical F value is determined by entering the F table (pp.723-24) at 3 degrees of freedom for the numerator and 8 degrees of freedom for the denominator for the level of significance given which in this case is 0.05.

Quesheip Use the number line below, where RS = 6y +2, ST=5y + 9, and RT= 13y - 1 a What is the value of y? b Find RS, ST, and RT
Simora [160]

Answer:

y = 6

RS = 38

ST = 39

RT = 77

Step-by-step explanation:

Given:

RS = 6y +2

ST=5y + 9

RT= 13y - 1

Solving (a): The value of y

From the given parameters, we understand that

RT = RS + ST

Substitute values for RS, ST and RT

13y - 1 = 6y + 2 + 5y + 9

Collect Like Terms

13y - 6y - 5y = 1 + 2 + 9

2y = 12

Divide both sides by 2

y = \frac{12}{2}

y = 6

Solving (b):

<em>The value of RS</em>

Substitute 6 for y in RS = 6y +2

RS = 6 * 6 + 2

RS = 36 + 2

RS = 38

<em>The value of ST</em>

Substitute 6 for y in ST=5y + 9

ST = 5 * 6 + 9

ST = 30 + 9

ST = 39

<em>The value of ST</em>

Substitute 6 for y in RT= 13y - 1

RT = 13 * 6 - 1

RT = 78 - 1

RT = 77
