Answer:
y = 57 - 3x
Step-by-step explanation:
Alice collected 57 skipping stones. And she skipped 3 stones a minute on her pond.
So. if y represents the number of stones left to her and x represents the number of minutes, then by the condition given we can write
y = 57 - 3x ..... (1)
So, this is equation of a straight line in the slope-intercept form. (Answer)

Answer:
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = 0.0505
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given mean of the Population 'μ' = 374
Variance of the Population σ² = 1090
Standard deviation of the Population 'σ ' = √1090 = 33.01
Given 'X' be a random variable in normal distribution

Z = - 1.64
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = P( Z < - 1.64 )
= 1- p(Z > 1.64)
= 1 - ( 0.5 + A(1.64)
= 0.5 - 0.4495
= 0.0505
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = 0.0505
