His brother spent 20. For Paul to $12 you need to times 4 by 3 to get 12. So you need times 5 by 4 which gives you the 20
I got it!! Ok are you ready to work on this problem???
Hello there!
The correct answer is option C
3x + 20x - 55 = -9
I am not sure if you wanted some more details but I hope this helps and if you do, just let me and I will edit it.
Good luck with your studies!
Happy New Year!~
The positive value of Z is 2.17.
What do you mean by normal distribution?
A data collection with a normal distribution is put up so that the majority of the values cluster in the middle of the range and the remaining values taper off symmetrically in either direction. Because of its flared appearance, a normal distribution's graphic representation is occasionally referred to as a bell curve. The specific shape may change depending on how the population is distributed, but the peak and curve are always symmetrical and in the centre.
The information can be represented in the standard normal curve below:
It is given that 97% of the standard normal curve lies between −z and z.
The area in between is 0.97 meaning that one side is (0.97)/2 = 0.485
In addition, the region not shaded is the level of significance represented by (1-0.97)/2 = 0.03/2 = 0.015
From the Z-Score table (0 to Z table), this probability corresponds to the Z value of Z= 2.17 and -2.17
Thus the positive value of Z is 2.17.
