Answer:

the subtraction property of equality

Step-by-step explanation:

Given

8x + 15 = 11x + 2

Subtract 15 from both sides of the equation

8x + 15 - 15 = 11x + 2 - 15

8x = 11x - 13

Answer:

the addition property of equality

Step-by-step explanation:

Compare step 1 with step 2 in the solution process:

step 1: -5x = -4x - 15

step 2: -x = -15

The variable was isolated on the left side of the equation by adding 4x to both sides. This is justified by the addition property of equality.

How many decibels is this? show work

slavikrds [6]

Answer:

115 dB

Explanation:

1. Given equation:

$\beta =10log(\frac{I}{I_0})\\\\ I_0=10^{-12}W/m^2$

2. Given intensity:

$I=0.315W/m^2$

3. Decibels

$\beta =10log(0.315/10^{-12})\\ \\ \beta =10log(315,000,000,000)\\ \\ \beta =10(11.498)=114.98\approx 115$

Which of the following statements is not true? A. If the probability of an event occurring is 1.5, then it is certain that eve

yawa3891 [41]

Answer:

Therefore, we conclude that the statement in (A) is incorrect.

Step-by-step explanation:

We have the following sentences:

A) If the probability of an event occurring is 1.5, then it is certain that event will occur.

B) If the probability of an event occurring is 0, then it is impossible for that event to occur.

We know that the range of probability of an event occurring is in the segment [0, 1]. In statement under (A), we have the probability that is equal to 1.5.

Therefore, we conclude that the statement in (A) is incorrect.
