For the two figures to be similar, the missing length must be 30.
<h3 /><h3>What is the missing length?</h3>
For the two figures to be similar, the dimension of each figures must be proportional to each other.
Let the missing length be x.
Hence,
x/25 = 24/20
We cross multiply
x × 20 = 24 × 25
x × 20 = 600
x = 600/20
x = 30
Therefore, for the two figures to be similar, the missing length must be 30.

Answer:
b
Step-by-step explanation:
Answer:
We need at least 4238 scores.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M
In which 
is the standard deviation of the population and n is the size of the sample.
How many random IQ scores must be obtained if we want to find the true population mean (with an allowable error of 0.5) and we want 97 percent confidence in the results
We need at least n scores, in which N is found when 
. So
We need at least 4238 scores.
Answer:
5 more than the absolute value of the cube of a number
The answer:
the main formula for finding the value of an ordered pair of the inverse of a function f(x) is as following:
if (x, f(x)) is an ordered pair, so the <span>ordered pair of the inverse of f(x) is (x', y') such that x'=f(x) and y'=x,
therefore, </span>If (9,33) is an ordered pair of the inverse of f(x), the <span>ordered pair of the function f(x) is (33, 9)</span>
