Answer:
k = -6.29
Step-by-step explanation:
91 - 2 + 7k + 1 = 46
add all like terms
90 + 7k =46
subtract
90 + 7k = 46
-90 -90
------------------------
7k = -44
divide
=
(these arent fractions thats just how i divide things :))
= -6.28571428571
round to nearest hundredth
k= -6.29
goes up to 9 because 5 makes 8 go up one when rounding
sorry for asking so many questions. hope this helps

To solve this question, you¨ll need to use a table of the standardized Normal distribution, or you could use a graphing calculator. The answer will be the cumulative property which will be a number with decimals. However, this represents the students who had a lower score then her, You´ll need to subtract this from 1 in order to get the opposite number, which will be the kids who scored higher. Be sure to multiply the result by 100 to get a percentage. Your answer should be 0.806 hope this helped!
Step-by-step explanation:
Hi, your question isn't totally complete. Here's the likely full question:
Random walk. A Java programmer begins walking aimlessly. At each time step, she takes one step in a random direction (either north, east, south, or west), each with probability 25%. She stops once she is at Manhattan distance r from the starting point. How many steps will the random walker take? This process is known as a two-dimensional random walk.
Write a program RandomWalker.java that takes an integer command-line argument r and simulates the motion of a random walk until the random walker is at Manhattan distance r from the starting point. Print the coordinates at each step of the walk (including the starting and ending points), treating the starting point as (0, 0). Also, print the total number of steps taken.
