Answer the questions while completing the tutorial. Pay attention to the dialogues!

1. Write the lines of code that takes the absolute value of the accelerations with respect to the x, y and z axis and stores the values as Local Variables

let xAccel = math.abs(input.acceleration("x"))
let yAccel = math.abs(input.acceleration("y"))
let zAccel = math.abs(input.acceleration("z"))

2. Write the lines of code that add all the accelerations together to get the total acceleration and stores the value as a Local Variable called "sum"

let sum = xAccel + yAccel + zAccel

3. Write the 'If statement' used if the sum of the acceleration value is less than 1400 milli-gravitys. Then write the code that will plot an image of the fake amount of WiFi if the acceleration in this 'If statement'

if (sum < 1400) {
    basic.showleds(`
. . . . .
. . . . .
. . # . .
. # # . .
# # # . .
`)
}

4. Write tje 'If statement' used if the sum of the acceleration value is greater than 1400 milli-gravitys but less than 1680 milli-gravitys. Then write the code that will plot an image of the fake amount of WiFi inside this 'If statement'

if (sum >= 1400 && sum < 1680) {
    basic.showleds(`
. . . . .
. . . # .
. . # # .
. # # # .
# # # # .
`)
}

5. Write the 'if statement' needed to display this specific plot image on the device

if (sum >= 1680) {
    basic.showleds(`
. . . . .
. . . . .
. . . . .
. . . . .
# . . . .
`)
}
