WILL MARK BRAINLIEST How would I be able to graph f(x) = (2x-1)(2x-5)? I just need to know the steps how to.
Answer:
Find the "zeros" and plug in points
Step-by-step explanation:
You can tell this graph is a parabola.
We can find the "zeros" of the graph to help us.
Find the zeros:
2x-1=0
2x=1
x=0.5
2x-5=0
2x=5
x=2.5
We can substitute values into f(x)=(2x-1)(2x-5) to graph.
You should get (1.5,-4) to be the vertex.

Step-by-step explanation:
The Ericsson method is one of several methods claimed to increase the likelihood of a baby girl. In a clinical trial, results could be analyzed with a formal hypothesis test with the alternative hypothesis of p>0.5, which corresponds to the claim that the method increases the likelihood of having a girl, so that the proportion of girls is greater than 0.5. If you have an interest in establishing the success of the method, which of the following P-values would you prefer: 0.999, 0.5, 0.95, 0.05, 0.01, 0.001? Why? The P-value of (0.999.05.095.005-001.0001) 2 is preferred because it corresponds to the sample evidence that most strongly supports the (null/ altenative)? hypothesis that the method (is/ is not)? effective.
Answer:
0.001
Step-by-step explanation:
Ericsson is claimed to increase the likelihood of a baby girl ;
Given the alternative hypothesis to buttress this claim :
HA : p>0.5
In other to establish the success of Ericsson's claim, then there must be significant evidence to reject the Null hypothesis ; hence adopt the alternative.
To Do this, we need a very small Pvalue ; such that it will be lesser than the α - value in other to reject the Null and adopt the alternative.
Recall ;
Pvalue < α ; We reject the Null
Therefore, from the options, we choose the smallest Pvalue as we want the Pvalue to be as small as possible.

If a = 20 mm, b = 12 mm, and m∠C = 80°, what is the approximate area of ABC?
Answer:
118.18 mm^2
Step-by-step explanation:
Sides a and b form angle C, so the information given is a side-angle-side (SAS) problem.
Use the formula [tex]A=\frac{1}{2}ab\sin{C}[/tex].
[tex]A=\frac{1}{2}(12)(20)\sin{80^\circ} \approx 118.18 \rm \,mm^2[/tex]
Min has a shelf filled with books. The books have different thicknesses. This line plot shows the thickness of each book. He piles the four thickest books on top of each other. How thick is the pile?
Answer:
[tex]$2\frac{1}{4} \ inch$[/tex]
Step-by-step explanation:
We have the four thickest books from the line plot given by
Two books of [tex]$\frac{1}{2}$[/tex] inch thick and the two books of [tex]$\frac{5}{8}$[/tex] inch thickness.
So when the two [tex]$\frac{1}{2}$[/tex] inch thick book is being piled on the top of a [tex]$\frac{5}{8}$[/tex] inch thick books.
Therefore, the total thickness of the pile of books is given by :
[tex]$=2 \times \frac{1}{2}+2 \times \frac{5}{8}$[/tex]
[tex]$=\frac{9}{4}$[/tex]
[tex]$=2\frac{1}{4} \ inch$[/tex]
Therefore, the thickness of the pile is [tex]$2\frac{1}{4} \ inch$[/tex] .
The addition is one of the four fundamental mathematical operations. The thickness of the pile is 4.75 inches.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
As per the given graph, the top four thickest books are:
2 books of thickness 1 1/8 inches2 books of thickness 1 1/4 inchesTherefore, the thickness of the pile is the sum of the thickness of the four books.
[tex]\text{The thickness of pile} = 1\frac18 +1\frac18 + 1\frac14 + 1\frac14\\[/tex]
[tex]= \dfrac98 +\dfrac98 + \dfrac54 + \dfrac54\\\\= 4.75[/tex]
Hence, the thickness of the pile is 4.75 inches.

Irene knows there are 2 cups in 1 pint. She writes the equation c=2p to find the number of cups, c, in any number of pints, p. Use the drop-down menus to complete the statements about Irene's equation.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as there are no options to select from.
However, a general explanation is as follows.
Given
[tex]2\ cups = 1\ pint[/tex]
Required
Is [tex]c = 2p[/tex] a correct expression?
Let
[tex]c = cups[/tex]
[tex]p = pint[/tex]
So:
[tex]2\ cups = 1\ pint[/tex]
becomes
[tex]2 * c = 1 * p[/tex]
[tex]2c = p[/tex]
Divide both sides by 2
[tex]c =\frac{1}{2}p[/tex]
Hence:
[tex]c = 2p[/tex] is incorrect

Answer:
B)
Step-by-step explanation:
let 's' = # shirts they can buy
8s + 45 ≤ 325
8s ≤ 280
s ≤ 35
they cannot purchase more than 35 shirts
first set up the equation:
let t = number of t-shirts
8t + 45 [tex]\leq[/tex] 325
solve for t:
subtract 45 from both sides
8t [tex]\leq[/tex] 280
divide both sides by 8
t [tex]\leq[/tex] 35
looking at the number line:
when placing this onto the numberline, there should be a close circle at 35 and the arrow should be going towards 0 to show that it is less than or equal to 35

Step-by-step explanation:
Given that,
Perpendicular = 17 units
Hypotenuse = 25 units
We need to find the value of x.
Using Pythagoras theorem to find x.
Hypotenuse² = base²+perpendicular²
25² = x² + 17²
x = 18.3 units
So, the value of x is equal to 18.3 units. No, the sides do not form a Pythagorean triplet.
What's the 11th term 5,15,45,135
Answer:
The 11th term is 295,245.
Step-by-step explanation:
We are given the sequence:
[tex]5, 15, 45, 135...[/tex]
And we want to find the 11th term.
First, let's determine whether this is an arithmetic sequence or a geometric sequence.
Arithmetic sequences have common differences, while geometric sequences have common ratios.
We can determine that our sequence is a geometric sequence because each subsequent term is triple the previous term: our common ratio is 3.
To find the 11th term, we can write an explicit formula for our sequence. The explicit formula for a geometric sequence is given by:
[tex]x_n=ar^{n-1}[/tex]
Where a is the initial term, r is the common ratio, and n is the nth term.
Since initial term is 5, and the common ratio is 3. Thus:
[tex]x_n=5(3)^{n-1}[/tex]
To find the 11th term, substitute 11 for n:
[tex]x_{11}=5(3)^{11-1}[/tex]
Evaluate. Thus, the 11th term is:
[tex]x_{11}=5(59049)=295245[/tex]

Step-by-step explanation:
In this question, we define a new operation in arithmetic, using xxas a symbol. a xxb = ab + a – b For example, 3xx7 = 21 + 3 - 7 = 17 a.Calculate 5 xx2 b. Calculate 3 xx1/2 c. Solve the equation x xx5 = 8
Answer:
a. 13 , b. = 4 , c. 2.2
Step-by-step explanation:
Given : a xx b = ab + b - a
So, no.1 xx no.2 = Product no.1 x no.2 + no.1 - no.2
As evident 3 xx 7 = (3 x 7) + 3 - 7 → 3 xx 7 = 21 + 3 - 7 = 17
Hence, 5 xx 2 = (5 x 2) + 5 - 2 → 5 xx 2 = 10 + 5 - 2 = 13
3 xx 1/2 = 3 (1/2) + 3 - 1/2 = 1.5 + 3 - 0.5 = 4
x xx 5 = 8
x xx 5 = 5x + x - 5
6x - 5 = 8
6x = 13
x = 2.16 ≈ 2.2
