How do I solve for b.

Mathematics

Arturiano [62]4 years ago
6 0
Since d is being subtracted from bc, we first add d to each side. Now we are left with a + d = bc.
Since b is being multiplied by c to be bc, we divide both sides by c.
We now have a/c + d = b
Your solution is: b = a/c + d

vagabundo [1.1K]

Answer:

28.4

Step-by-step explanation:

Given that:

Mean, m = 31.3

Standard deviation, s = 2.8

Since, data is normally distributed :

P(x < 0.15) gives a Z value of - 1.036

Using the Zscore formula :

Z = (x - mean) / standard deviation

-1.036 = (x - 31.3) / 2.8

-1.036 * 2.8 = x - 31.3

-2.9008 = x - 31.3

-2.9008 + 31.3 = x

28.3992 = x

The temperature which correlates to the bottom 15% of the distribution is 28.4

<span>A student divided the given number by 100 that resulted to 28.003 in his chart. So what we are looking for this situation is the value of the number before it was divided by 100.
To get the value, simply multiply the result by 100
=> 28.003 x 100
=> 2800.3
 by dividing 100 to the given number, we simply move the value to the right in a value of hundreds.
