Answer:
x=8/5
Step-by-step explanation:
2/3(18x-12)=7-3(x-3)
2/3(18x-12)=7-3x+9
12x-8=-3x+16
12x-(-3x)-8=16
12x+3x-8=16
15x-8=16
15x=16+8
15x=24
x=24/15
simplify
x=8/5
I believe the answer is there are 3 stems of greenery in each vase.
You just do 8 times 37.5% or 0.375 and get 3.
Hey there!
The shape you're looking for is a
rectangular pyramid. A rectangular pyramid has a rectangular base and four triangles that make up the four sides and meet up at the points at the very top. I've attached a picture so you can see it for yourself.
Hope this helped you out! :-)
Answer:
The requirements that are necessary for a normal probability distribution to be a standard normal probability distribution are <em>µ</em> = 0 and <em>σ</em> = 1.
Step-by-step explanation:
A normal-distribution is an accurate symmetric-distribution of experimental data-values.
If we create a histogram on data-values that are normally distributed, the figure of columns form a symmetrical bell shape.
If X
N (µ, σ²), then
, is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is, Z
N (0, 1).
The distribution of these z-variates is known as the standard normal distribution.
Thus, the requirements that are necessary for a normal probability distribution to be a standard normal probability distribution are <em>µ</em> = 0 and <em>σ</em> = 1.
2^3=2*2*2=4*2=8
the answer is 8
