<span>The one-way ANOVA or one – way analysis of
variance is used to know whether there are statistically substantial
dissimilarities among the averages of three or more independent sets. It
compares the means between the sets that is being examined whether any of those
means are statistically pointedly dissimilar from each other. If it does have a
significant result, then the alternative hypothesis can be accepted and that
would mean that two sets are pointedly different from each other. The symbol, ∑
is a summation sign that drills us to sum the elements of a sequence. The
variable of summation is represented by an index that is placed under the
summation sign and is often embodied by i. The index is always equal to 1 and
adopt values beginning with the value on the right hand side of the equation
and finishing it with the value over head the summation sign.</span>

Answer:
A)18in.
Step-by-step explanation:
Given,
A trapezoid Area= 216 sq
The length of its longer base=2x
The length of its shorter base= x
Height of Trapezoid = 8in
Area of Trapezoid= 1/2h(a+b)
216=1/2 x 8(2x+x)
216=4(2x+x)
216/4=3x
54=3x
54/3=x
18=x
Length of shorter base=18
Length of longer base=2x18=36
Hence, the length of the shorter base is 18in
Option A) is correct
Answer:
1/4
Step-by-step explanation:
Let x = number the spinner lands on
P(X = 1) = 1/4
P(X = 2) = 1/4
P(X = 3) = 1/4
P(X = 4) = 1/4
The spins are independent events as their probabilities are not affected by whether or not the other event happens
Therefore, the probability that you land on a number 2 given that your first spin landed on number 1 is still 1/4
