Find three consecutive odd integers whose sum is -45. Find the largest<br> integer

Troyanec [42]

x = the first integer.

x + 2 = the second integer.

x + 4 = the third integer.

x + x + 2 + x + 4 = -45

Combine like terms.

3x + 6 = -45

Subtract 6 from both sides.

3x = -51

Divide both sides by 3

x = -17

x + 2 = -17 + 2 = -15

x + 4 = -17 + 4 = -13

The largest integer is -13

A survey shows that the probability that an employee gets placed in a suitable job is 0.65. A psychometric test consultant claim

fgiga [73]

Answer:

A survey shows that the probability that an employee gets placed in a suitable job is 0.65.

So, the probability he is in the wrong job is 0.35.

The test has an accuracy rate of 70%.

So, the probability that the test is inaccurate is 0.3.

Thus, the probability that someone is in the right job and the test predicts it wrong is $0.65\times0.3=0.195$

The probability that someone is in the wrong job and the test is right is $0.35\times0.7=0.245$
