Answer:

90x

Step-by-step explanation:

30x+60x=?

If you want to solve this easily, you can just remove x and add 30x + 60x.

30+60

We know that 30 + 60 is 90. So we will add x to 90.

90x

Now you have your answer!

Hope this helps!

Binomial distribution formula: P(x) = (n  k) p^k * (1 - p)^n - k

a) Probability that four parts are defective = 0.01374

P(4 defective) = (25 4) (0.04)^4 * (0.96)^21

P(4 defective) = 0.01374

b) Probability that at least one part is defective = 0.6396

Find the probability that 0 parts are defective and subtract that probability from 1.

P(0 defective) = (25 0) (0.04)^0 * (0.96)^25

P(0 defective) = 0.3604

1 - 0.3604 = 0.6396

c) Probability that 25 parts are defective = approximately 0

P(25 defective) = (25 25) (0.04)^25 * (0.96)^0

P(25 defective) = approximately 0

d) Probability that at most 1 part is defective = 0.7358

Find the probability that 0 and 1 parts are defective and add them together.

P(0 defective) = 0.3604 (from above)

P(1 defective) = (25 1) (0.04)^1 * (0.96)^24

P(1 defective) = 0.3754

P(at most 1 defective) = 0.3604 + 0.3754 = 0.7358

e) Mean = 1 | Standard Deviation = 0.9798

mean = n * p

mean = 25 * 0.04 = 1

stdev = \sqrt{np(1-p)}

stdev = \sqrt{(25)(0.04)(1-0.04)} = 0.9798

Hope this helps!! :)

What is the value of x??
Feliz [49]

Answer:

I. 5

Step-by-step explanation:

  • 140° and 8x° are on the straight angle and they are both equal 180°

to find the value of x:

140 + 8x = 180

8x = 180 - 140

8x = 40

x = 40/8

x = 5

xxTIMURxx [149]

Answer:

1, 7, 17, 31

Step-by-step explanation:

2(1)² + 1 - 2 = 3-2 = 1

2(2)² + 1 - 2 = 9-2 = 7

2(3)² + 1 - 2 = 19-2 = 17

2(4)² + 1 - 2 = 33-2 = 31
