If XY = 5x-3 and XZ=44, find x and the value of YZ

mixer [17]

The midpoint of a line divides the line into equal halves.

The value of x is 5
The value of YZ is 22

Given that:

$XY = 5x -3$

$XZ = 44$

Y is the midpoint of XZ. So:

$XZ = 2 \times XY$

$44 = (5x - 3 ) \times 2$

$44 = 10x - 6$

Collect like terms

$10x = 44 +6$

$10x = 50$

Divide both sides by 10

$x = 5$

Recall that: Y is the midpoint of XZ

This means that:

$YZ = \frac12 XZ$

$YZ = \frac12 \times 44$

$YZ = 22$

Hence, the value of x is 5 and YZ is 22

consider the distribution of monthly social security (OASDI) payments. Assume a normal distribution with a standard deviation of

Orlov [11]

Answer:

$\mu = x - z(\sigma)$

$\mu = 1214.87 - 0.67(116) \\\\\mu = 1214.87 - 77.72 \\\\\mu = \$1137.15$

Therefore, the mean monthly payment is $1137.15.

Step-by-step explanation:

What is Normal Distribution?

We are given a Normal Distribution, which is a continuous probability distribution and is symmetrical around the mean. The shape of this distribution is like a bell curve and most of the data is clustered around the mean. The area under this bell shaped curve represents the probability.

We are asked to find the mean monthly social security (OASDI) payment.

Mean monthly payment = μ = ?

We are given that the standard deviation is $116

One-fourth of payments are above $1214.87

One-fourth means 25%

$P(X > x )= P(Z > z ) = 0.25\\\\P(X < x )= P(Z < z) = 1 - 0.25\\\\P(X < x )= P(Z < z) = 0.75\\\\$

From the z-table, the z-score corresponding to 0.75 is found to be 0.67

$z = 0.67$

The mean is found by

$x = \mu + z(\sigma)$

$\mu = x - z(\sigma)$

Where

x = $1214.87

z = 0.67

σ = $116

$\mu = 1214.87 - 0.67(116) \\\\\mu = 1214.87 - 77.72 \\\\\mu = \$1137.15$

Therefore, the mean monthly payment is $1137.15.
