LMN≅PQR

1 answer:

7 0

X = 56°.

Based on the congruence statement, m∠L = m∠P; m∠M = m∠Q; and m∠N = m∠R.

Since m∠L = 72°, m∠P = 72°.
Since m∠N = x°, m∠R = x°.
We are given that m∠Q = 52°.

We can find the value of x by subtracting the given angles from 180:
180-(72+52) = 180-124 = 56°

Find the inverse of the relation. Use proper notation. {(8,−1),(−8,−1),(−2,−8),(2,8)} please help!!

tiny-mole [99]

Answer: The inverse relation is { (-1, -8), (-1, -8), (-8, -2), (8, 2) }

The inverse is effectively the opposite of the original relation. It undoes what the original relation does. So we'll swap the x and y values for each given point in the form (x,y). Something like (8,-1) becomes (-1,8). The other points follow the same pattern as well.

A medical test has been designed to detect the presence of a certain disease. Among people who have the disease, the probability

Oksi-84 [34.3K]

Answer:

a) 0.497

b) 0.0047

Step-by-step explanation:

a) The probability that the person actually has the disease

$\frac{0.06 *0.93}{0.06 *0.93 + 0.06 *0.94} = 0.497$
