The first answer is a letter c - normal
distribution. The normal distribution is the most significant
and most generally used distribution in statistics. It is also known as the Gaussian or standard
normal distribution, is the <span>probability
distribution<span> that plots all of its values in an
even fashion, and most of the results are positioned around the probability's
mean. Values are equally likely to plot either above or below the mean. And the
second answer is letter d - sampling distribution. In statistics, it is the
probability distribution of a given statistic centered on a
random sample. Sampling distributions are significant
in statistics because they deliver a major simplification to the statistical
inference.</span></span>
Answer:
Octagon
Step-by-step explanation:
180(n - 2) = 1080
n - 2 = 1080/180
n - 2 = 6
n = 8
=> Polygon with 8 sides
=> Octagon
Answer:
<em>The salesperson needs to sell 10 stereos to make the same money on both plans</em>
Step-by-step explanation:
We'll analyze both choices for the compensation plans of a salesperson.
One plan offers a fixed weekly salary of $250 plus a $25 commission for each stereo sold. The function than models this plan is:
P1=250+25x
Where x is the number of stereos sold.
The other plan offers no fixed salary but a $50 commission on each stereo sold. The function of this plan is:
P2=50x
To find the equilibrium point for both plans, we make P1=P2:
250+25x=50x
Simplifying:
25x=250
Solving:
x = 250 / 25 = 10
The salesperson needs to sell 10 stereos to make the same money on both plans
Answer:
(5,3)
Step-by-step explanation:
x=17-4y
x=17-4x+8
x=25-4x
5x=25
x=5
y=x-2
y=5-2
y=3

Answer:
The perimeter of the given rectangle = 20 units.
Step-by-step explanation:
Length of the rectangle = 6 units
The width of the rectangle = 4 units
Now Perimeter of the Rectangle = 2 ( LENGTH + WIDTH)
⇒Here, perimeter = 2 ( 6 units + 4 units ) = 2 x ( 10 units)
= 20 units
Hence, the perimeter of the given rectangle = 20 units.
