Answer:

f=6 and s=18

Step-by-step explanation:

Let's solve your system by substitution.

s+f=24;s=3f

Rewrite equations:

s=3f;f+s=24

Step: Solves=3ffor s:

s=3f

Step: Substitute3fforsinf+s=24:

f+s=24

f+3f=24

4f=24(Simplify both sides of the equation)

(Divide both sides by 4)

f=6

Step: Substitute6forfins=3f:

s=3f

s=(3)(6)

s=18(Simplify both sides of the equation)

Answer:

f=6 and s=18

ValentinkaMS [17]

Answer:

$H_o:\mu = 48\\H_a:\mu\neq48$

Step-by-step explanation:

Given : . The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a true mean temperature, 48°F, ideal for a certain type of German pilsner.

To Find : The owner of the brewery does not agree with the refrigerator manufacturer, and claims he can prove that the true mean temperature is incorrect.

Solution:

We are given that refrigerators that are supposed to maintain a true mean temperature, 48°F.

Claim : The true mean temperature is incorrect.

So, null hypothesis and alternate hypothesis will be :

$H_o:\mu = 48\\H_a:\mu\neq48$

So, Option D is true .

Find the slope of the line 2y=42-6x

Dovator [93]

2y = -6x + 42.....in y = mx + b form, the m stands for the slope
y = -6/2x + 42/2....reduce
y = -3x + 21.....so the slope is -3
