Answer:

( 7x + 11 )( 7x- 11 )

Step-by-step explanation:

( 7x + 11 )( 7x- 11 )

Because 7*7 is 49

-11*11= -121

7*11=77

-7*11= -77

77-77=0

so the answer is 49x^2-121

zaharov [31]

As <GEB is on the same line with FG while AB is parallel to CD, <GEB is corresponding to the angle of 50°

The equation would be:
<GEB=50°(corr. <s, AB//CD)

thus the answer is C.50

A website offers a coupon such that each customer has a

sweet-ann [11.9K]

Answer:

62.29%

Step-by-step explanation:

The probability of Aya being offered a coupon on at least one of the six days she visits the website is 100% minus the probability that she is not offered a coupon on any of the six days, which is described by a binomial probability with zero successes in six trials with a probability of succes p = 0.15.

$P = 1 - (\frac{6!}{(6-0)!0!}* p^0*(1-p)^{6-0})\\P = 1 - (1* 1*(1-0.15)^{6})\\P=0.6229=62.29\%$

The probability that Aya will be offered a coupon on at least one of the days she visits the website is 62.29%.
