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.

Answers

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.

Find a Quadratic equation whose roots are 1.5+√2 and 1.5-√2​

Answers

Answer:

x² - 3x + 0.25 = 0

Step-by-step explanation:

Given a root x = a then the corresponding factor is (x - a)

Given roots x = 1.5 + [tex]\sqrt{2}[/tex] and x = 1.5 - [tex]\sqrt{2}[/tex] then the factors are

(x - (1.5 + [tex]\sqrt{2}[/tex] ) ) and (x - (1.5 - [tex]\sqrt{2}[/tex] ) ) , that is

(x - 1.5 - [tex]\sqrt{2}[/tex] ) and (x - 1.5 + [tex]\sqrt{2}[/tex] )

The equation is then the product of the factors

(x - 1.5 - [tex]\sqrt{2}[/tex] )(x - 1.5 + [tex]\sqrt{2}[/tex] ) = 0 ← expand factors using FOIL

(x - 1.5)² - ([tex]\sqrt{2}[/tex] )² = 0

x² - 3x + 2.25 - 2 = 0

x² - 3x + 0.25 = 0

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.

Answers

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

A gallon of paint can cover 360 square feet. The radius of a standandard NBA basketball is 4.75 inches. How many basketballs will the paint cover? ( note 144 square inches in 1 square foot )

Answers

Answer:  182 basketballs

===========================================================

Explanation:

We're told that 1 square foot is 144 square inches (this is from 12*12 = 144, since 12 inches = 1 ft).

So because of this, 360 square feet converts to 360*144 = 51,840 square inches.

One gallon of paint can cover 51,840 square inches.

Now let's find the surface area of the sphere, aka ball.

It has a radius of r = 4.75 inches, so,

SA = 4*pi*r^2

SA = 4*pi*(4.75)^2

SA = 90.25pi

SA = 283.528736986479 which is approximate

The surface area of one ball is roughly 283.528736986479 square inches.

Divide the amount of area the paint can cover over the surface area of one basketball:

(51,840)/(283.528736986479) = 182.838609415709

This rounds down to 182. We round down because we won't have enough paint to cover the 183rd basketball.

One gallon of paint can cover 182 basketballs.

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

Answers

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

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?

Answers

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 inches

Therefore, 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.

What are Equivalent fractions?

Equivalent fractions are fractions that represent the same value or amount, despite having different numerators and denominators.

In other words, equivalent fractions have the same ratio or proportion, but may be written in different forms.

For example, the fractions 1/2 and 2/4 are equivalent fractions because they represent the same amount, which is half of a whole.

Also, 3/5 and 6/10 are equivalent fractions because they both represent three-fifths or 60% of a whole.

Which of the following statements are true about the graph of f(x) = 6(x + 1)2 -9?
Check all of the boxes that apply.

a. The vertex is (1, -9).

b. The graph opens upward.

c. The graph is obtained by shifting the graph of f(x) = 6(x + 1)2 up 9 units.

d. The graph is steeper than the graph of f(x) = x2.

e. The graph is the same as the graph of f(x) = 6x2 + 12x - 3.

Answers

Answer:

Step-by-step explanation:

a. The vertex is (1, -9).  False.  The vertex is (-1, -9).

b. The graph opens upward.  True.  That coefficient '6' is positive.

c. The graph is obtained by shifting the graph of f(x) = 6(x + 1)2 up 9 units.  False.  It's DOWN 9 units.

d. The graph is steeper than the graph of f(x) = x^2.  True.  The given function increases 6 times faster than does x^2.

e. The graph is the same as the graph of f(x) = 6x2 + 12x - 3.

Let's put f(x) = 6(x + 1)^2 -9 into standard form.  Expanding the first term, we get f(x) = 6(x^2 + 2x + 1) - 9, or f(x) = 6x^2 + 12x + 6 - 9.  YES, TRUE

6x - 8x + 24 = 18
