Six times a number is at least four less than eight times the number. If x represents the number, which will help find the numbe
AleksAgata [21]
(X x 6) = (X x 8) -4

Ps. Make sure yoi dont times the (X x 8) by -4 the -4 is by itself.

I personally found it easier thinking if there is a difference of 4 between 6 x X and 8x X then it must be 2x2 as the difference between 6 and 8 is 2. therefore 4 divided by 2 = 2 and 2 x 2 = 4

Therefore x = 2

Apple uses cheap labor in factories in China to manufacture its cell phones. The probability that a phone is defective is 0.02.
emmasim [6.3K]

Let x be the random variable representing defective phone. Let n be the sample size. Let p be the probability that phone is defective.

Given: n=500, p= 0.02

From given information we know that x is random variable such that p is the probability of success and it is constant for each trial. Sample size n is fixed.

X follows Binomial distribution with parameters n=500 and p=0.02

a). The average number of defective phone

E(x) = n*p = 500 * 0.02 = 10

The average number of defective phones is 10.

b)Probability of getting 5 defective phones.

P(X=5) = (nCx) p^{x}  (1-p)^{n-x}

= (500C5) 0.02^{5}  (1-0.02)^{500-5}

= 0.037

The probability of getting exactly 5 defective is 0.037.
