A company that produces fine crystal knows from experience that 15% of its goblets havecosmetic flaws, while the remaining 85% a
Vinvika [58]

Answer:

The probability that exactly two have flaws is P (x=2) = 0.2376

Step-by-step explanation:

Here

Success= p= 0.15

Failure = q= 0.85

total number= n= 8

Number chosen = x= 2

Applying the binomial distribution

P (x=x) = nCx p^x(q)^n-x

P (x=2) = 8C2 0.15 ²(0.85)^8

P (x=2) = 0.2376

The success is chosen about which we want to find the probability. Here we want to find the probability that exactly two have flaws so success would be having flaws therefore p = 0.15

Which of the following is the solution set to the inequality −25x+14>20? Select one: A. x < -64 B. x > -64 C. x < -1
Sindrei [870]

Answer:

x< -0.24

Step-by-step explanation:

So this is going to sound stupid, but I got x< -0.24 which is just not an option, but this is how I got it...

-25x+14>20

subtract 14 from each side

-25x>6

divide each side by -25

x< -0.24

I switch the way the sign was facing bc I divided by a negative.

Now I know that this must be wrong, but it makes the most sense because I am pretty sure I did all of the math right. Sorry this probably didnt help , but I did a lot of work to try and get the right answer, so Im not putting that work to waste

Which of the following is algebraically equivalent to the sum of 4x^2 -8x +7 And 3x^2-2x-5
VARVARA [1.3K]

All you have to do, is combine like terms. Let's go through it:

(4x^2-8x+7)+(3x^2-2x-5)

Arrange it so you can easily combine like terms:

4x^2+3x^2-8x-2x+7-5 = 7x^2-10x+2

So, your answer for the sum is 1) 7x² - 10x + 2
