You have a 5 question multiple choice test. Each question has four choices. You don’t know any of the answers. What is the experimental probability that you will guess exactly three out of five questions correctly?

Type your answer below using complete sentences.

The type of bias in the questionnaire is question wording bias or survey question bias, influenced by the way the question is phrased to imply evolution being synonymous with promoting science, potentially leading respondents to answer in line with what they perceive to be the socially desirable response.

The type of bias present in the questionnaire regarding teaching only evolution in schools is an example of question wording bias or survey question bias. When the interviewer asks respondents if they favor promoting science by teaching only evolution, the question implies that evolution is synonymous with science and that alternative perspectives are not scientific. This phrasing can lead respondents to answer in a manner that aligns with what they perceive as the socially desirable response, rather than their true beliefs, which can also be similar to the concept of social desirability bias.

Additionally, using the phrase promoting science might influence the respondents' answers because it frames the question in a way that one answer appears more 'pro-science' than the other, potentially leading to an inflated percentage of respondents in favor of teaching only evolution in schools. This kind of bias prevents the collection of accurate data regarding the population's true stance on the issue being surveyed.

It would cost $2338.75 to build a deck that is 22 feet by 18.5 feet at a rate of $5.75 per square foot.

To calculate the cost of building a deck, we need to find the total area of the deck and then multiply it by the cost per square foot.

The area of a rectangle (deck) is given by the formula:

Area = length * width

Given that the deck has a length of 22 feet and a width of 18.5 feet, we can calculate the total area:

Area = 22 feet * 18.5 feet

Area = 407 square feet

Now, to find the total cost of building the deck, we multiply the area by the cost per square foot:

Total cost = Area * Cost per square foot

Total cost = 407 square feet * $5.75/square foot

Total cost = $2338.75

So, it would cost $2338.75 to build a deck that is 22 feet by 18.5 feet at a rate of $5.75 per square foot.

The expression 4 × 24 in distributive form will be 4 × ( 20 + 4 ) and the value of 96.

An expression 4x24 is given.

We have to write it using distributive property.

What is the distributive property of multiplication ?

The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC.

As per the question ;

Expression is 4x24.

Let's rewrite it in form of distributive property ;

4 × 24

= 4 × ( 20 + 4 )

So ,

It is now in form A ( B + C ) , where ; A = 4 , B = 20 and C = 4

⇒ 4 × ( 20 + 4 )

= 80 + 16

= 96

Thus , the expression 4 × 24 in distributive form will be 4 × ( 20 + 4 ) and the value of 96.

Answer:

$43888.75

Step-by-step explanation:

We have been given that in 2010 the federal debt (in millions) was $13,561,623 and the population of the U.S. was 309 million.

[tex]\text{The federal debt per capita}=\frac{\text{Total debt}}{\text{Total population}}[/tex]

[tex]\text{The federal debt per capita}=\frac{\$13,561,623}{309}[/tex]

[tex]\text{The federal debt per capita}=\$43888.74757[/tex]

[tex]\text{The federal debt per capita}\approx \$43888.75[/tex]

Therefore, the federal debt per capita in 2010 was $43888.75.

The formula for expense is given as:

E = V q + F

where, E = expense, V = variable cost, F = fixed cost

Therefore the equation should be:

E = 8.8 q + 14.50

So the answer is “False”

Segments and lines can be named using the letters that represent the points on them, such as AB or line AB.

In geometry, segments and lines are fundamental elements. A line is an infinite set of points extending in opposite directions, while a segment is a finite portion of a line with two distinct endpoints. These concepts are essential for understanding geometric shapes, angles, and spatial relationships in mathematics.

In mathematics, the name of a segment and the name of a line can be written differently by using the letters that represent the points on the segment or the line. For example, a segment between points A and B can be written as AB, while a line passing through points A and B can be written as line AB or simply AB. It is important to note that in both cases, the order of the points does not matter, as AB is the same as BA.

Equation for the length L of the rope as a function of the distance x from P to the ground is,

⇒ L = √((x-2)²+50²)

Since L is to the second pole, not x, we can't simply say that;

⇒ x² + y²= L² using the Pythagorean Theorem.

Since, due to that we simply increase the original height by 2, decreasing x by 2.

We can, however, say that ;

⇒ (x-2)² + y² = L²

Plugging 50 as y in, we get ;

⇒ (x-2)² + 50² = L².

Square rooting both sides, we get;

⇒ L = √((x-2)²+50²)

Thus, Equation for the length L of the rope as a function of the distance x from P to the ground is,

⇒ L = √((x-2)²+50²)

The expression 2^4 \u00b7 2^{-7} simplifies to 2^{-3}, which is the same as 1/2^3 or 1/8.

The expression 2^4 \u00b7 2^{-7} can be simplified using the properties of exponents, specifically the law that states when multiplying expressions with the same base, you add the exponents. Here, we are multiplying 2 raised to the power of 4 with 2 raised to the power of -7. Therefore, we add the exponents 4 and -7 together to get 2^{4-7} = 2^{-3}.

To simplify further, remember that a negative exponent indicates the reciprocal of the base raised to the positive of that exponent. Hence, 2^{-3} = 1/2^3 = 1/8. Therefore, 2^4 \u00b7 2^{-7} simplifies to 1/8.

Step-by-step explanation:

4 x 6 = 24 square feet

24/12 = 2

 so 1 person for every 2 square feet

1 mile - 5280 feet

4 x 5280 = 21120

21120 x 15 = 316800 square feet

316800/2 = 158,400 people

We are given a total size of 24 2/3 feet of wrapping paper. Convert this into fraction of denominator 6:

total paper = 24 2/3 = 74/3 = 148/6 feet

Subtract 5/6 foot:

remaining paper = 148/6 – 5/6 = 143/6 feet

Divide by 11:

each piece = (143/6) ft / 11 = 143/66  ft = 2.17 ft

Given

John had a roll containing of wrapping paper  

[tex]=24\tfrac{2}{3}[/tex]

First, he must cut off 5/6 foot because it was torn.

He wants to divide it into 11 pieces.

To proof

As given in question

John had a roll containing of wrapping paper

[tex]=24\tfrac{2}{3}[/tex]

[tex]=\frac{74}{3}[/tex]    ( solving the mixed fraction form)

 First, though, he must cut off 5/6 foot

than we get

[tex]= \frac{74}{3} - \frac{5}{6}[/tex]

Taking the L.C.M of 3 and 6 is 6

[tex]=\frac{148-5}{6}[/tex]

[tex]=\frac{143}{6}[/tex]

=23.83 feet (approx)

He wants to divide it into 11 piece

length of the each piece

[tex]=\frac{23.83}{11}[/tex]

length of the each pieces be 2.16 feet ( approx)

Hence proved

The inverse of y = 5 x² + 10 is , y = √ ( ( x / 5 ) - 2 )

What is an Inverse Function?

An inverse function is a function that undoes the action of the another function. To find the inverse of a function, write the function y as a function of x i.e. y = f(x) and then solve for x as a function of y.

                                                   f⁻¹ ( x ) = y

Given data ,

y = 5 x² + 10

Now interchange the variable x and y , we get

x = 5 y² + 10

Subtract 10 from both sides , we get

x - 10 = 5 y²

Divide by 5 on both sides ,

( x / 5 ) - 2 = y²

Therefore , y = √ ( ( x / 5 ) - 2 )

Hence , the inverse f⁻¹ ( x ) = y = √ ( ( x / 5 ) - 2 )
