The first answer is 80, and the second answer is still 65.5. Hope this helps!
The following is the plot of the normal percent point function. where \phi is the cumulative distribution function of the standard normal distribution and Φ is the probability density function of the standard normal distribution.
Answer: 90
Explanation: The pattern is add 3 then the next set is double. [9-6=3 then 18-9=9(or doubled)] and the pattern continues and because 45-42=3 the next number set would be 45 doubles which equals 90.
2(2d+4)=-3(d+2)
4d+8=-3d-6
4d+3d=-6-8
7d=-14
d=-14/7
d=-2
Answer:
Step-by-step explanation:
In a parallelogram, the opposite sides are parallel and also equal. The opposite angles are also equal.
In parallelogram ABCD, side AD is parallel to side BC. Also, side AB is opposite and parallel to side CD. This means that AB = CD
Sides CD and AB have lengths of y + 18 and 4y, respectively. Therefore,
y + 18 = 4y
Subtracting y from the left hand side and the right hand side of the equation, it becomes
y + 18 - y = 4y - y
3y = 18
y = 18/3 = 6
Therefore, the length of AB is
AB = 4y = 4 × 6
AB = 24
