5x - 2. Just combine like terms, and distribute the + to the second term.
Answer:
Yes, y=5x is a direct variation and the constant of variation is 5 .
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).
D because 1.29 plus 2.75 is 4.04(the money that he used to make the case) and subtract that with $12 and you get $7.96 as the profit.
Answer:
9/10
Step-by-step explanation:
To solve this, we simply need to find the common denominator, which in this case, is 10
5 x 2 = 20
1/5 = 2/10
7/10 + 2/10 = 9/10
Thus, our answer is 9/10
