You can use substitution or elimination or graphing to solve the equation. Since both of the equations are in slope intercept form it will be easier to use substitution or to graph it and find the point of interception.

You can write (6x=10)=(-4x-20), because both expressions are equal to the same thing, so they're equal to each other. From that, you easily solve for 'x', and then write that number back into one of the original equations to find 'y' .

Assume the random variable X is normally distributed with mean mu equals 50 and standard deviation sigma equals 7. Compute the p
defon

Answer:

P(X>34) = 0.9889

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 50

Standard Deviation, σ = 7

We are given that the distribution of random variable X is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(X greater than 34)

P( X > 34) = P( z > \displaystyle\frac{34 - 50}{7}) = P(z > -2.2857)

= 1 - P(z \leq -2.2857)

Calculation the value from standard normal z table, we have,  

P(X>34) = 1 - 0.0111= 0.9889= 98.89\%

The attached image shows the normal curve.
