(−0.775)
Step-by-step explanation:
-2/5=3/8+p
subject p by taking 3/8 to the other side
p=-2/5 - 3/8
we will take the negative sign out by putting brackets
p=-(2/5+3/8)
p=-(16+15)/40
p=-31/40
Answer:
<h2>The intensity of the sound is 3.16, approximately</h2>
Step-by-step explanation:
The equation that determines decibel levels is
Where represents the intensity of the sound and the ten power represents the softest sound, that ratio is the comparison to find the decibels.
In this case, we have 125 decibels. So, we need to use this value in the formula to find the intensity
Therefore, the intensity of the sound is 3.16, approximately. Which is at the same level as a loud rock concert.
The data points that fall within the mean absolute deviation are 2.9 and 3.1.
<h3>What is the mean absolute deviation?</h3>
The mean absolute deviation is the mean average distance between every data point and the mean of the data set.
From the information given:
- Mean of the data set = 5.3
- Mean absolute deviation = 2
The mean absolute deviation is:
= (|5.3 - 2|)/1
= 3.3
Thus, the data points that fall within the mean absolute deviation are 2.9 and 3.1.

V = 20√(273 + t )
when v = 329
∴ 329 = 20 √(273 + t )
∴ √(273 + t ) = 329/20 = 16.45
273 + t = 16.45² = 270.6025
∴ t = -2.3975 ≈ -2 (<span> Rounded to the nearest degree )

Answer:
B. 20%
Step-by-step explanation:
The cafeteria sold 50 slides of pizza, 92 chicken nugget plates, and 108 nacho bowls, we can add all of them together and get 250 lunches.
50 out of 250 is 20%.
Therefore, the probability that the next customer will buy a slice of pizza is 20%.
