  7/8

Step-by-step explanation:

7/8 differs from 1 = 8/8 by 1/8.

8/7 differs from 1 = 7/7 by 1/7.

1/8 is smaller than 1/7, so 7/8 is closer to 1.

Answer:

We are 95% confident that the true proportion of U.S. adults who live with one or more chronic conditions is between 39.7% and 46.33%

Step-by-step explanation:

From the question we are told that

  The  sample  proportion is \(\r p = 43\%  = 0.43\)

   The  standard error is \(SE =  0.017\)

Given that the confidence level is 95%  then the level of significance is mathematically represented as  

      \(\alpha =  (100-95)\%\)

=>   \(\alpha = 0.05\)

Generally from the normal distribution table the critical value  of  \(\frac{\alpha }{2}\) is  

   \(Z_{\frac{\alpha }{2} } =  1.96\)

Generally the margin of error is mathematically represented as

     \(E = Z_{\frac{\alpha }{2} } *  SE\)

=>    \(E = 1.96 *  0.017\)

=>     \(E = 0.03332 \)

Generally 95% confidence interval is mathematically represented as

      \(\r p -E <  p <  \r p +E\)

=>   \(0.43 -0.03332 <  p <  0.43 + 0.03332\)

=>    \( 0.39668 <  p <  0.46332\)

Converting to percentage

\( (0.39668 * 100)<  p <  (0.46332*100)\)        

\( 39.7\% <  p < 46.33 \%\)

The entropy of the random variable X in this case is approximately 1.585 bits.

The entropy of a random variable X is a measure of the uncertainty associated with it. In this case, the random variable X is the number of selections required to choose the number 3.

Since the numbers are selected without replacement, the possible values for X are 1, 2, and 3, and the probabilities for each value are:

P(X=1) = 1/3

P(X=2) = 2/7

P(X=3) = 4/7

The entropy of a random variable X in bits is given by the formula:

H(X) = -∑P(X) log2(P(X))

Plugging in the probabilities above:

H(X) = -(1/3 log2(1/3) + 2/7 log2(2/7) + 4/7 log2(4/7))

H(X) = 1.585 bits

So, the entropy of the random variable X in this case is approximately 1.585 bits.

Step-by-step explanation:

One root being i, an imaginary number is throwing me off.. but I can give it a shot if youd like.

So a coefficient is the number Infront of the X. so for 6X^2, the coefficient is 6.

It says the Leading Coefficient is 3. The one option for that is 3x^4, so that will be the in the first blank.

The exponents now (the little numbers) start with 4 and go down 1 after each block. Which means the last two blocks will have no little numbers since it would be 1 and 0. Those don't need exponents.

For the block after the 21x^2, we have two choices. Either 6x or 2x

For the last block we have two choices also.

8 or 24

To find if it's 6x or 2x...

If rena divides a square into 8 equal part then 1/8 is a unit fraction which she has to write as a label for each parts.

A fraction represents a part of a whole.

Given that rena divides a square into 8 equal part.

A division is a process of splitting a specific amount into equal parts.

Let the whole square is divided into eight equal parts.

Which can be represented by 1/8.

Where the numerator 1 represents the whole and eight represents the parts.

The unit fraction for each part is 1/8 because the square is divided into 8 equal parts.

This means each part is one eighth of the whole.

Hence, if rena divides a square into 8 equal part then 1/8 is a unit fraction which she has to write as a label for each parts.

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

Explanation:

I'll denote the cars with the labels A and B.

Car A has a fuel rating of 40 mpg (miles per gallon) and car B gets 20 mpg.

Let,

Since car A gets 40 mpg, and uses up x gallons, then it travels 40x miles. Multiply the fuel rating with the number of gallons used to determine the distance traveled. Car B travels 20y miles since it gets 20 mpg.

Overall, the two cars travel a combined distance of 40x+20y miles. This is set equal to the 2100 miles stated to form the equation 40x+20y = 2100.

Let's divided every term by 20

40x+20y = 2100

40x/20+20y/20 = 2100/20

2x+y = 105

Then isolate y to get

y = 105-2x

We'll use this equation later.

------------------------

The two cars use up a total of 65 gallons, which means,

x+y = 65

Then we'll plug in y = 105-2x and solve for x.

x+y = 65

x+105-2x = 65

-x+105 = 65

-x = 65-105

-x = -40

x = 40

Car A (the 40 mpg car) used 40 gallons. It traveled 40x = 40*40 = 1600 miles.

Car B (the 20 mpg car) used y = 105-2x = 105-2*40 = 25 gallons of gas. Or you could note that if x = 40, then x+y = 65 must lead to y = 25. It traveled 20y = 20*25 = 500 miles.

The two cars combined distance is 1600+500 = 2100 miles to help verify the answers.

Mary Lou Mason's total taxes on her purchase would be $1.37.

Taxes are mandatory payments to the government that are used to fund public services such as infrastructure, education, and health care. Taxes can be direct, such as income taxes, or indirect, such as sales taxes.

Mary Lou Mason's total purchase was $19.14.

To calculate the total taxes for her purchase, we can use the following formula:

Tax = (State Sales Tax %) x (Total Purchase) + (County Tax %) x (Total Purchase)

Therefore, the total taxes for Mary Lou Mason's purchase would be:

Tax = (6.5%) x ($19.14) + (1.5%) x ($19.14)

Tax = (0.065 x 19.14) + (0.015 x 19.14)

Tax = 1.24 + 0.13

Tax = $1.37

Mary Lou Mason's total taxes on her purchase would be $1.37.

The length of a 45° arc with a radius of 4 miles is approximately 3.14 miles, calculated using the formula for arc length.

To determine the length of a 45° arc given a radius of 4 miles, we can use the formula: Arc length = (angle measure / 360°) x 2πr, where r is the radius of the circle and π is a constant equal to approximately 3.14.

Substituting the given values into the formula, we get: Arc length = (45° / 360°) x 2π(4 mi)Arc length = (1/8) x 2π(4 mi)Arc length = (1/8) x 8π Arc length = π

The length of the 45° arc is approximately 3.14 miles.

Summary: To find the length of a 45° arc of a circle, we use the formula: Arc length = (angle measure / 360°) x 2πr. Given a radius of 4 miles, we can substitute the values into the formula to get the length of the 45° arc, which is approximately 3.14 miles.

The correct statement is;

False,  because x = \(cos^-^1({\frac{-1}{2} )\) is in the interval \(( -\frac{\pi }{2} , \frac{\pi }{2} )\) that is, \(cos^-^1({\frac{-1}{2} )\) = \(\frac{2\pi }{3}\). So all solutions of cos x = -1/2 will be  x = 2π/3 + 2nx and x = 4π/3 + 2nx.

Option D

From the information given, we have that;

All solutions are cos x = -1/2 are given by x = 4x/2 + 2πx

There are multiple solutions to the equation cos x = -1/2, and they are denoted by the values x = 2π/3 + 2nx and x = 4π/3 + 2nx

Such that n is an integer.

This is so because the cosine function repeats itself every 2π, or its period. We therefore multiply the general answer by multiples of 2 to obtain all solutions.

The formula x = 4x/2 + 2πx implies that each solution can be reached by x being multiplied by 4/2 and 2πx being added.
