Given:
μ = 500 days, the population mean
σ = 60 days, the population standard deviation
Therefore
μ + σ = 560
μ - σ = 440
μ + 2σ = 620
μ - 2σ = 380
μ + 3σ = 680
μ - 3σ = 320
The figure shown below illustrates the normal distribution
About 68% of the total area lies in x = (μ-σ, μ+σ)
About 95% of the total area lies in x = (μ-2σ, μ+2σ)
About 99.7% of the total area lies in x = (μ-3σ, μ+3σ).
Answer:
1. 3212 = 3.212 X 10 of 3
2. because it easier to write and read
Answer:
- y-intercept = 100
- x- intercept = -5.26
Step-by-step explanation:
- $100 initial membership fee
- $19 monthly fee
<u>Function of relationship:</u>
<u>y- intercept:</u>
- x =0 ⇒ y = 19*0 + 100 ⇒ y = 100
<u>x - intercept:</u>
- y = 0 ⇒ 0 = 19x + 100 ⇒ 19x = -100 ⇒ x = -100/19 ⇒ x = -5.26
124 inches of a frame is the required amount. 31 times 4 is 124.
