Company B is better in salary then Company A.

<u>Step-by-step explanation:</u>

Here we have , The annual salary for a computer technician at Company A ranges from $41,000 to $63,000, with a mean of $58,000. At Company B, the annual salary for the same position ranges from $45,000 to $$65,000, with a mean of $56,000. We need to find  BEST compares the salaries of computer technicians for the two companies . Let's find out:

The annual salary for a computer technician at Company A ranges from $41,000 to $63,000, with a mean of $58,000 , So Mean :

⇒ Mean = \frac{41000+63000}{2}

⇒ Mean = \frac{104000}{2}

⇒ Mean = 52,000 , But mean given here is $58,000 , which differ in

⇒ 58000-52000

⇒ $6000

The annual salary for a computer technician at Company A ranges from $45,000 to $65,000, with a mean of $56,000 , So Mean :

⇒ Mean = \frac{45000+65000}{2}

⇒ Mean = \frac{110000}{2}

⇒ Mean = 55,000 , But mean given here is $56,000 , which differ in

⇒ 56000-55000

⇒ $1000

Since, Mean of Company B differs less than actual range , than Company A . So , Company B is better in salary then Company A.

Given that 5W = 2P + 3R find the value of P when W = 4 and R = −4
Olenka [21]

Answer:

P = 16

Step-by-step explanation:

Given

5W = 2P + 3R ← substitute W = 4 and R = - 4 into the equation

5(4) = 2P + 3(- 4), that is

20 = 2P - 12 ( add 12 to both sides )

32 = 2P ( divide both sides by 2 )

16 = P
