If there are a number of different sounds being produced simultaneously, the resulting intensity is the sum of the individual intensities. How many decibels louder is the sound of quintuplets crying than the sound of one baby crying?
The sound of quintuplets crying is 7 dB louder than the sound of one baby crying because a factor of five in intensity corresponds to a 7 dB increase in sound intensity level.
Explanation:The question asks how many decibels louder the sound of quintuplets crying would be compared to the sound of one baby crying. To calculate this, we need to understand that intercity levels in decibels (dB) are measured logarithmically. This means that for every ten-fold increase in intensity, the sound level goes up by 10 dB. We also know that a factor of five in intensity corresponds to an increase of 7 dB.
If one baby crying produces a certain sound intensity, then five babies (quintuplets) crying simultaneously would increase the intensity by a factor of five. Hence, the sound of quintuplets crying would be 7 dB louder than the sound of one baby crying, based on the given references.

According to the general equation for conditional probability, if P(A^B)=3/4 and P(B)=4/5, what is P(A B)?
0.96
Explanation:A rule of conditional probability states that
P(A∣B)=P(A∩B)P(B)
So in this case it would be:
P(A∣B)=4556=4⋅65⋅5=2425=0.96

Si S es el 150% de T, qué tanto por ciento de T es (S + T)?
If S is 150% of T, then to find what percentage (S + T) is of T, we calculate (S + T) / T * 100. By substituting S = 1.5T into the equation, we determine that (S + T) equals 250% of T.
Explanation:If S is the 150% of T, this implies that S is 1.5 times T (since 150% can be expressed as 1.5 in decimal form). To express S as a percentage of T, we can set up the equation S = 1.5T.
Now, we are asked to find what percentage of T is (S + T). To find this, we simply add S and T together: S + T = 1.5T + T = 2.5T. Now, to express this sum as a percentage of T, we divide the sum by T and then multiply by 100.
So, ((S + T) / T) * 100 = (2.5T / T) * 100 = 2.5 * 100 = 250%. Therefore, (S + T) is 250% of T.
To find the percentage that (S + T) is of T, we first need to find the value of S and T. The given information states that S is 150% of T. This means that S = 1.5T. To find (S + T), we substitute the value of S in terms of T: (1.5T + T) = 2.5T.
Now, to find the percentage that (S + T) is of T, we divide (S + T) by T and multiply by 100: ((2.5T / T) imes 100) = 250%.
Therefore, (S + T) is 250% of T.

Suppose △ITH≅△APG.
Which congruency statement is true?
It is given that the triangles ITH and APG are congruent.
When the two triangles are congruent, then the corresponding angles and sides are congruent to each other.
By being congruent, the corresponding angles which are congruent are:
[tex]IT \cong AP, TH \cong PG, IH \cong AG[/tex]
Therefore, [tex]IH \cong AG[/tex]

what is the equation of the line shown in this graph.
simplify.
-5 ( x - 3) + 2 ( a - 9)
-5x + 2a + 33
-5x + 2a + 4
-5x + 2a - 33
-5x + 2a - 4
Answer:
Step-by-step explanation:
-5(x+3) + 2(a-3
-5*x =-5x
-5*3= -15
2*a=2a
2*9=18
-15+18=3
so the answer is -5x+2a-3
