Answer:
x=3
Step-by-step explanation:
∠DBC+∠VBC is 180° since it is a straight line, ∠VBC=20x+5
The sum of all angles in a triangle is 180°, 9x-2 + 40° +∠DBC=180°
To find x, you can find ∠DBC first. *Don't forget BRACKETS
∠DBC=180-(20x+5)
∠DBC=180-(9x-2 + 40°)
Now equal the equations to each other to find x.
180-(20x+5)=180-(40+9x-2)
180-20x-5=180-40-9x+2
175-20x=142-9x
175-142=20x-9x
33=11x
x=33/11
∴x=3

8a-25b-5 is the answer to ur question
The correct option is: a female who weighs 1500 g
<em><u>Explanation</u></em>
<u>Formula for finding the z-score</u> is: 
Newborn males have weights with a mean
of 3272.8 g and a standard deviation
of 660.2 g.
So, the z-score for the newborn male who weighs 1500 g will be.......

According to the normal distribution table, 
Now, newborn females have weights with a mean
of 3037.1 g and a standard deviation
of 706.3 g.
So, the z-score for the newborn female who weighs 1500 g will be.......

According to the normal distribution table, 
As we can see that the <u>probability that a newborn female has weight of 1500 g is greater than newborn male</u>, so a newborn female has the weight of 1500 g that is more extreme relative to the group from which he came.
