The statement that does not model the situation:

(1) For citizens 18-29 years of age, the rate of change in voting rate was greatest between the years 2000-2004.

A confidence interval is a range of values that are constrained by the statistic's mean and that is likely to include an unidentified population parameter. The proportion of likelihood, or certainty, that the confidence interval would include the real population parameter when a random sample is drawn several times is referred to as the confidence level.

Given:

Voting rates in presidential elections from 1996-2012 are modeled below.

Voting Rates in Presidential Elections, by Age, for the Voting-Age Citizen Population: 1996-2012

The interpretation of the statements is given below;

(1) For citizens 18-29 years of age, the rate of change in voting rate was greatest between the years 2000-2004.

No, the greatest was in the year 2008.

(2) From 1996-2012, the average rate of change was positive for only two age groups.

True, the age groups are 39.6 to 45.0 and 69.1 to 72.0.

(3) About 70% of people 45 and older voted in the 2004 election.

Yes.

(4) The voting rates of eligible age groups lie between 35 and 75 percent during presidential elections every 4 years.

Yes, the interval difference is 4.

Therefore, option (1) is incorrect.

Answer:

Gasoline 7%

Step-by-step explanation:

2500 * 0,07 = 175

Number * 0, percent = answer

Gasoline is the part of Shaquira's budget which is $175.

In mathematics, a value or ratio that can be expressed as a fraction of 100 is known as a percentage. To find the % of a number, divide it by its value, then multiply the result by 100. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

As per the given data:

Shaquira's monthly income = $2,500

Monthly Budget Utilities = 18% of income

Entertainment = 9% of income

Rent = 51% of income

Gasoline = 7% of income

Food = 15% of income

To find which part is $175 let's calculate all parts:

Monthly Budget Utilities = (18/100) × 2,500 = $450

Entertainment = 9% × 2,500 = $225

Rent = 51% × 2,500 = $1275

Gasoline = 7% × 2,500 = $175

Food = 15% × 2,500 = $375

Hence, gasoline is the part of Shaquira's budget which is $175.

Answer:

Melanie is correct

Step-by-step explanation:

35% of 85 is 29.75 so take that away from the original price and you get 55.25

This means the price will be 55.25$

Answer:

Melanie is correct since 65% of $85.00 is $55.25.

Step-by-step explanation:

The original price of the shoes is $85.00. That is 100% of the price of the shoes since 100% is a whole amount.

The discount on the shoes is 35%.

100% - 35% = 65%

That means the sale price is 65% of the original price. Now we calculate 65% of $85.00.

65% of $85.00 =

= 0.65 * $85.00

= $55.25

Answer: Melanie is correct since 65% of $85.00 is 55.25.

Answer:

One Way: 79 + 62H + 15H = X

Second Way: 79 + ((62 + 15) x H) = X

Step-by-step explanation:

Given that a plumber charges a customer a one-time service fee of $ 79, $ 62 per hour for labor, and a surcharge of $ 15 per hour due to the call being an emergency, to write an expression to represent the total charges for the plumber in two different ways, with H representing the number of hours the job takes, the following equations should be formulated:

79 + 62H + 15H = X

So, for example, if the job had lasted 2 hours, the equation would apply as follows:

79 + 62x2 + 15x2 = X

79 + 124 + 30 = X

233 = X

79 + ((62 + 15) x H) = X

In the case, if the work had lasted 1 hour, the equation would apply as follows:

79 + (62 + 15) x 1) = X

79 + 77 x 1 = X

79 + 77 = X

156 = X

The total charge when there is an emergency is $79 + $77h. The total charge when there is no emergency is $79 + $62h.

There are two ways of representing the total charges of the plumber,one when there is an emergency call and two when there is no emergency call. The total charge a function of the one-time service fee, labor charge and the surcharge.

Total charge when there is an emergency = one-time service fee + labor charge per hour + surcharge per hour

$79 + $62h + $15h

= $79 + $77h

Total charge when there is no emergency = one-time service fee + labor charge per hour

$79 + $62h

Answer:

Approximately 110.6 grams remain at the beginning of the 17th day.

Step-by-step explanation:

At the beginning of the first day, the mass of the substance was 500 grams.

It decreases by 9% per day.

And we want to determine the mass of the sample at the beginning of the 17th day.

First, we need to find our ratio of decay. Since it decreases by 9% or 0.09 each day, the mass of the substance after each subsequent day will be 100% - 9% or 1 - 0.09 or 0.91 of the previous day.

We can write a exponential function to model this. An exponential function has the form:

[tex]f(x)=ar^x[/tex]

Where a is the initial term and r is the rate.

Let x represent the number of days after the first day. Substitute 500 for a and 0.91 for r:

[tex]f(x)=500(0.91)^x[/tex]

The 17th day is 16 days after the first day. So, the amount of mass remaining on the beginning of the 17th day is when x = 16. Substitute:

[tex]f(x)=500(0.91)^{16}[/tex]

Approximate. Therefore:

[tex]f(x)\approx110.6\text{ grams}[/tex]

Approximately 110.6 grams remain at the beginning of the 17th day.

Step-by-step explanation:

Answer: m = -1/2

Use (y2-y1)/(x2-x1) to find the slope.

Domain: All real numbers, or (-∞,∞) depending on how you want to write it.

Range: [-4, ∞)

Vertex: (-2, -4)

Axis of symmetry: x = -2

Interval of increase: (-2, ∞)

Interval of decrease: (-∞, -2)

Y-int: (0, 0)

X-int/Zero/Solution(s): (-4, 0) and (0, 0)

For a polynomial function like this, which is a quadratic function, the domain is always negative infinity to positive infinity, or all real numbers.

The range is the lowest y-value to the highest y-value. The lowest y-value for this is at the vertex, but the function has no upper limit for the y-value.

The vertex is the point that you can very clearly see is at the tip of the graph.

Axis of symmetry is the vertical line that splits the graph in half at the vertex.

Interval of increase is the interval x values for which the function is increasing. The function increases to the right of the vertex.

Interval of decrease is to the left of the vertex.

The y-intercept is clearly (0, 0), where the graph intersects the y-axis.

The x-intercepts are also clear, since you can see where the graph intersects the x-axis.

Answer:

YES

Step-by-step explanation:

Any line that is tangent to a circle is always perpendicular to the radius of the circle, forming a right angle at the point of tangency.

Therefore, ∆BAC is a right triangle if it satisfy the pythagorean triple rule which says that c² = b² + a²

Where,

c = the hypotenuse = 30

b = 24

a = 2(9) = 18

Thus:

30² = 24² + 9²

900 = 900 (this is true)

Therefore, line AB is tangent to circle O.
