Answer:

width = 40 feet, length = 90 feet

Step-by-step explanation:

length = 2w + 10

width = w

Perimeter = 260

Perimeter of rectangle = 2length + 2width

Sub the values into that equation:

260 = 2(2w + 10) + 2(w)

260 = 4w + 20 + 2w

260 = 6w + 20

260 - 20 = 6w

240 = 6w

w = 240/6

w = 40

So now we know the width of the garden is 40 feet.

To find the length, substitute the width into the length equation:

length = 2w + 10

length = 2(40) + 10

length = 90 feet

length = 90 feet, width = 40 feet

Answer:

x= {0,1,2,3,4,5,6,7,8,9,10}

Step-by-step explanation:

As the random variable takes the values from 0 ----10 it can be written as

x= {0,1,2,3,4,5,6,7,8,9,10}

The probability of the defective and non defective items would be

P ( defective) = 12/ 100 = 0.12

P ( non defective) = 1-0.12= 0.88

Since the events are independent the probability of defective items in the randomly 10 selected items would be given

P (1/10) * 0.12 +P ( 2/10) * 0.12 + P(3/10)*0.12 ,---------,+P (10/10) * 0.12

Similarly the probability of non defective item s would be

P (1/10) * 0.88 +P ( 2/10) * 0.88 + P(3/10)*0.88 ---------P (10/10) * 0.88

That is the individual probability is multiplied with the probability of the defective or non defective items to get the total probability of defective and non defective items as the events are independent.
