Assignment: complementary events investigation mrs. hudson plans to give a 10 question multiple choice exam in which each question has 4 options. each question counts for 1 point. a score of 8 or more is a passing score while 7 or less is a failing score. the probabilities of guessing a certain number of questions correctly are listed in the table below. number of questions correct probability for guessing correctly 0 0.05631351 1 0.18771172 2 0.28156757 3 0.25028229 4 0.14599800 5 0.05839920 6 0.01622200 7 0.00308990 8 0.00038624 9 0.2861 10 0.95 i. compute the probability of answering 8 or more questions correctly by calculating the probability with a direct sum and by using complements. ii. how do the two approaches compare? if tyler wants to pass his exam, should he study?

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
