Suppose you just received a shipment of twelve televisions. Three of the televisions are defective. If two televisions are rando
qwelly [4]

Answer: The probability that both televisions work is 0.5625 .

The probability at least one of the two televisions does not​ work is 0.4375.

Step-by-step explanation:

Given : Number of televisions received in shipment= 12

Number of defective televisions received in shipment= 3

Then proportion of defective televisions =\dfrac{3}{12}=0.25

Using binomial probability formula, the probability of getting success in x trials is given by :-

P(x)=^nC_xp^x(1-p)^{n-x}

If two televisions are randomly​ selected, then the probability that both televisions work will be :-

P(0)=^2C_0(0.25)^0(0.75)^2=(0.75)^2=0.5625

The probability at least one of the two televisions does not​ work will be :-

P(x\geq1)=1-P(0)=1-0.5625=0.4375

Hi Lawrence!

---------------------------------------------------

We Know:

Powersports Plus: $30 an hour plus a non-refundable deposit of $50.

Sun & Surf: $20 an hour plus a non-refundable deposit of $80.

---------------------------------------------------

Equation:

x = per hour

y = total

Powersports: 30x + 50 = y

Sun and Surf: 20x + 80 = y

---------------------------------------------------

Solution: (Add the deposit then start adding hourly costs)

Powersports: 80, 110, 140

Sun and Surf: 100, 120, 140

---------------------------------------------------

Answer: After <u>3 hours</u> both companies will cost the same amount of money.

---------------------------------------------------

Hope This Helps :)

The area of a soccer field at 7700 yd.². The width of the field is 70 yards. What is the perimeter of the field?
mario62 [17]
Since you know the area and the width, you can divide the area by the width to find the length. This gives you a length of 110 yards. To find the perimeter of the soccer field, you would add all the side lengths together. Since the width is 70, you would add 70 + 70, along with the length, 110 + 110. This gives you a perimeter of 360.
