#2: The number of data values is 14.

#3: The unit is: 21 ÷ 14.

And it is 1.5.

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.

Y=25x+35
kow [346]

Answer:

The equation is in the form y=mx+b, where m=slope, b=y-intercept.

The y-intercept is 35: so the line goes through the y-axis at (0,35).

The slope is 25: so we need to count out the slope as rise over run, or 25 up and 1 to the right, starting from the y-intercept.
