In a multiple choice test there are 10 questions. each question has 5 choices how many ways can they complete the test no two consecutive answers

1310720

Step-by-step explanation:

Given,

Total number of questions = 10,

Number of choices = 5,

If there are no two consecutive answers,

That is, if we have options a, b, c, d and e for each question,

Then, a could not be the answer of two consecutive questions,

We could pick 1 out of 5 answers for the first question and then for the remaining 9 questions we have only have 4 choices,

Hence, the total number of ways = 5 × 4 × 4 × 4 × 4 × 4 × 4 × 4 × 4 × 4

i have no clue at all sorry

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
