There are three questions, and three choices of answers (A, B and C) for each question. Given that only one of the possible choices (A, B and C) is correct for each question, state the probability that the student guesses:
Q1: 1 correct answer. Q2: 2 correct answer
Q3: 3 correct answer. Q4: 0 correct answer

Please use tree diagram to explain.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type

alaska, florida, nevada, south dakota, texas, washington and wyoming, tenessee and new hampshire.
