Answer:
a number = 1
Step-by-step explanation:
Determining if the method of randomization is either <u>appropriate</u> or <u>not</u> for each given situation includes:
A. Inappropriate
B. Appropriate
C. Appropriate.
<h3>What is randomization?</h3>
Randomization is the process of assigning research participants by chance to separate treatment groups.
Using a random drawing to assign subjects to groups and <u>flipping a fair coin</u> to assign participants to the experimental or control groups are instances of randomization.
Thus, the randomization method for experiment A is inappropriate, unlike experiments B and C.

#SPJ1
Answer:
she has to minus just as she did before.
Step-by-step explanation:
230-39=191
233-42=191
the reason as to why they have the same answer is because it was first 230 but it later it was 233.so just minus as before.hope it will help goodbye
<u><em>Answer:</em></u>
1)
f(x)→ ∞ when x→∞ or x→ -∞.
2)
when x→ ∞ then f(x)→ -∞
and when x→ -∞ then f(x)→ ∞
<u><em>Step-by-step explanation:</em></u>
<em>" The </em><em>end behavior</em><em> of a polynomial function is the behavior of the graph of as approaches positive infinity or negative infinity. The degree and the leading coefficient of a polynomial function determine the end behavior of the graph "</em>
1)
a 14th degree polynomial with a positive leading coefficient.
Let f(x) be the polynomial function.
Since the degree is an even number and also the leading coefficient is positive so when we put negative or positive infinity to the function i.e. we put x→∞ or x→ -∞ ; it will always lead the function to positive infinity
i.e. f(x)→ ∞ when x→∞ or x→ -∞.
2)
a 9th degree polynomial with a negative leading coefficient.
As the degree of the polynomial is odd and also the leading coefficient is negative.
Hence when x→ ∞ then f(x)→ -∞ since the odd power of x will take it to positive infinity but the negative sign of the leading coefficient will take it to negative infinity.
When x→ -∞ then f(x)→ ∞; since the odd power of x will take it to negative infinity but the negative sign of the leading coefficient will take it to positive infinity.
Hence, when x→ ∞ then f(x)→ -∞
and when x→ -∞ then f(x)→ ∞
Answer:
x = 7
Step-by-step explanation:
all triangles add up to 180
(90 from the right angle)
90 + (4x) + (5x +27) = 180
117 + 9x = 180
<u>-117 - 117</u>
9x = 63
x = 63/9
x = 7
