Z-score is computed by the equation below,
z-score = (x - μ) / σ
where x is the data point, μ is the mean and σ is the standard deviation. Substituting the known values,
z-score = (28,000 - 34,000) / $4000
z-score = -1.5
Answer:
The answer is 25 blocks east
Step-by-step explanation:
the reason why I say that is because if you go west (25 blocks) you will have to go back east because east is the opposite of west like north is the opposite of south
You mutiply the 50 by 2 to get 100 but would change the 41 and multiply that by two and get 82/100
2800 + 1.18x = y
x = monthly sales
y = monthly income
y needs to be at least 6400 so that means;
2800 + 1.18x ≥ 6400
1.18x ≥ 6400 - 2800
x ≥ (6400 -2800) / 1.18
x ≥ 3050
So she needs to earn at least 3050, which means <span>≥ 3050</span>
