Dx-y+ab=z solve for x

Mathematics
1 answer:
saul85 [17]2 years ago
4 0

Answer:

\huge x = \frac{z + y - ab}{d}

Step-by-step explanation:

dx-y+ab=z

First move (- y + ab ) to the other side of the equation

dx = z + y - ab

Divide both sides by d to make x stand alone

\frac{dx}{d}  =  \frac{z + y - ab}{d}  \\

We have the final answer as

x = \frac{z + y - ab}{d}  \\

Hope this helps you

Tpy6a [65]

Answer: 2718

Step-by-step explanation:

Given: Mean score = 85

Standard deviation = 5

Let x be the score of a random student that follows normal distribution.

Then, the probability that a student scored between 90 and 95 will be

P(90< x < 95)\\\\=P(\dfrac{90-85}{5}

The number of students scored between 90 and 95 = 0.1359 x (Total students)

= 0.1359 (20000)

= 2718

Hence, The number of students scored between 90 and 95 = 2718

topjm [15]
Let the number of deluxe that Pacific has be x
the number that Caribbean has will be (x+18)
the number that Mediterranean has will be (3x-25)
total b=number of deluxe in the 3 ships will be:
x+(x+18)+(3x-25)
5x-7=928
5x=928+7
x=935/5
x=187
Hence the Pacific has 187, Caribbean has 187+18=205, Mediterranean has (3*187-25)
