-78 = -6 (p - 4)i don't understand it

Distribution is one of the most important terms of math you need to know.

Distributing, in this case, is when you take the -6 and multiply the terms in the parenthesis.

When you do that. You’ll get -78 = -6p+24.

*Remember: a negative times a negative is always positive. A positive times a negative is always negative. If you need more help with this tip, please feel free to reply if you need any better tips and tricks.

Now, you’re going to solve -78-24 (since you switch the sign when you bring one term to the opposite of the equation).

Then you’ll have -102 = -6p

Lastly, instead of multiplying, you divide -102 by -6.

Your final answer should be 17 = p (or flip it to make it p = 17).

Answer:

(a) P (none) = 0.005873

(b) P ( at least one household ) = 0.9941

(c) P ( at most one household ) = 0.9960

(d) not wrong

Step-by-step explanation:

Given data

probability P = 29% = 0.29

no of sample n = 15

tv show X = 50

to find out

the probability that none of the households

the probability that at least one household

the probability that at most one household

If at most one household is tuned to 50 Minutes, does it appear that the 19% share value is wrong

solution

the probability that none of the households is tuned to 50 Minutes is

P (none) = 10C0 × $P^{0}$ × $(1 - 0.29)^{15}$

P (none) = $(0.71)^{15}$

P (none) = 0.005873

and the probability that at least one household is tuned to 50 Minutes is

P ( at least one household ) = 1 - P(none)

P ( at least one household ) = 1 - 0.005873

P ( at least one household ) = 1 - 0.005873

P ( at least one household ) = 0.9941

the probability that at most one household is tuned to 50 Minutes is

P ( at most one household ) = P (none) + P (x=1)

P ( at most one household ) =0.9941 + 10C1 × $(0.23)^{1}$ × $(0.71)^{14}$

P ( at most one household ) = 0.9960

and in last part If at most one household is tuned to 50 Minutes it appear that the 19% share value is not wrong

because P( at most one household ) is not zero

An inspector at a factory examines 320 drinking glasses, and 12 of them have defects. The inspector then examines 560 drinking g

fgiga [73]

Answer: 539 without defects

Step-by-step explanation: Im pretty sure we have to turn 12/320 into a percent, which is 0.0375, or 3.75%

So with that information, we need to find 3.75% of 560.

do 0.0375 x 560, which is 21.

21 are defects, so do 560 - 21 is 539.
