You can find the answer by multiplying the number of people by the number of sq miles.
8441 * 964

Answer:

Sue rode 1885 miles total

Step-by-step explanation:

There are 31 days in March, 30 in April, and 30 in May.

31 * 12 + 30 * 12 + 30 * 12 = 1092

There are 30 days in June and 31 in august.

30 * 13 + 31 * 13 = 793

Now we find the total:

1092 + 793 = 1885

The value of the z statistic for testing equality of the proportion of smokers in 1995 and 2010 = 2.05

Step-by-step explanation:

Complete Question

In the past decades there have been intensive antismoking campaigns sponsored by both federal and private agencies. In one study of national smoking trends, two random samples of U.S. adults were selected in different years: The first sample, taken in 1995, involved 4276 adults, of which 1642 were smokers. The second sample, taken in 2010, involved 3908 adults, of which 1415 were smokers. The samples are to be compared to determine whether the proportion of U.S. adults that smoke declined during the 15-year period between the samples.

Let p₁ be the proportion of all U.S. adults that smoked in 1995. Let p₂ denote the proportion of all U.S. adults that smoked in 2010.

The value of the z statistic for testing equality of the proportion of smokers in 1995 and 2010 is

A. z = 1.39.

B. z = 1.66.

C. z = 2.05.

D. z = 4.23.

Solution

The test statistic for two samples test is given as

z = (p₁ - p₂)/σ

σ = √{[p₁(1-p₁)/n₁] + [p₂(1-p₂)/n₂]}

p₁ = Proportion of smokers in 1995 = (1642/4276) = 0.384

n₁ = 4276

p₂ = Proportion of smokers in 2010 = (1415/3908) = 0.362

n₂ = 3908

σ = √{[0.384(1-0.384)/4276] + [0.362(1-0.362)/3908]}

σ = √[(0.384×0.616/4276) + (0.362×0.638/3908)] = √(0.0000553189 + 0.0000590983) = √0.0001144172 = 0.0106965976 = 0.010697

z = (p₁ - p₂)/σ

z = (0.384 - 0.362)/0.010697

z = 2.05

Hope this Helps!!!

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

Explanation:

If Hannah saves 30%, then she pays the remaining 70%, which then converts to the decimal form 0.70

The 15% discount leads to her paying the remaining 85% and that converts to the decimal 0.85

We'll multiply 0.70 and 0.85 to find the net discount

0.70*0.85 = 0.595

After combining both discounts, she pays 59.5% of the original price.

If the original price was $75, then she pays 0.595*75 = 44.625 = 44.63 dollars after applying both discounts.

No, 34.05 is not greater than 34.59.

When comparing two numbers, we look at their digits from left to right.

In this case, both numbers start with 34, which means they have the same value in the tens place.

However, when we move to the decimal part, 0.05 is smaller than 0.59.

Therefore, 34.05 is smaller than 34.59.

Where:

Now we proceed to determine quantities related to percentages:

2.8 mm as a per cent of 2.24 cm

x = (2.8 mm / 22.4 mm) × 100 %

x = 12.5 %

1.) inverse proportion : 1kx = y

2) direct proportion. y = kx

Answer:

21.77

Step-by-step explanation:

Applying,

V = (4/3)π(R²-r²)³/²................. Equation 1

Where  V = Volume of the resultant shape, R = radius of the sphere, r = radius of the hole bored, π = pie

From the question,

Given: R = 2, r = 1

Constant: π = 3.14

Substitute these values into equation 1

V = 4/3(3.14)(2²-1²)³/²

V = (12.56/3)(3)³/²

V = 4.19(5.196)

V = 21.77

The value of 'n' for which the division of x^(2n-1) by x + 3 leaves a remainder of -80 is n = 1.

To find the value of 'n' for which the division of x^(2n-1) by x + 3 leaves a remainder of -80, we can use polynomial long division. Let's perform the division step by step:

Write the dividend and divisor in polynomial long division format:

_________________________

x + 3 │ x^(2n-1) + 0x^(2n-2) + 0x^(2n-3) + ...

Divide the leading term of the dividend (x^(2n-1)) by the leading term of the divisor (x). The result is x^(2n-1)/x = x^(2n-2).

Multiply the divisor (x + 3) by the quotient obtained in the previous step (x^(2n-2)). The result is x^(2n-2) * (x + 3) = x^(2n-1) + 3x^(2n-2).

Subtract the result obtained in step 3 from the original dividend:

x^(2n-1) + 0x^(2n-2) + 0x^(2n-3) + ... - (x^(2n-1) + 3x^(2n-2)) = -3x^(2n-2) + 0x^(2n-3) + ...

Bring down the next term of the dividend (which is 0x^(2n-3)) and repeat steps 2-4 until the remainder is constant.

Since we are given that the remainder is -80, we can set the remainder equal to -80 and solve for 'n'.

-3x^(2n-2) + 0x^(2n-3) + ... = -80

Since the remainder is constant (-80), it means that all the terms with x have been canceled out in the division process. Therefore, we can deduce that the highest power of x in the divisor (x + 3) is 0.

This implies that x^(2n-2) = 0, and for any value of 'n', the exponent 2n-2 should be equal to zero. Solving this equation:

2n-2 = 0

2n = 2

n = 1

Therefore, the value of 'n' for which the division of x^(2n-1) by x + 3 leaves a remainder of -80 is n = 1.

The probability of drawing a king from a standard deck of 52 cards is 1/13.

In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.

To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).

The total number of possible outcomes is 52 because there are 52 cards in the deck.

The favorable outcomes, in this case, are the four kings.

Therefore, the probability of drawing a king is given by:

Probability = (Number of favorable outcomes) / (Number of possible outcomes)

= 4 / 52

= 1 / 13

Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.

This means that out of every 13 cards drawn, on average, one of them will be a king.

It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.

Each draw is independent, and the probability of drawing a king is constant.

Graphing, substitution, and elimination are three methods for solving systems of equations. While they all aim to find the solution(s) to a system of equations, there are some important differences in how they work and when they are most appropriate to use.

Graphing involves plotting the equations on the same coordinate system and finding the point(s) where the graphs intersect. This method is visual and can be useful for understanding the overall behavior of the equations, but it can be time-consuming and inaccurate if the graphs are not precise enough. Graphing is most appropriate when the equations are simple and have integer solutions, or when a visual representation of the problem is necessary.

Substitution involves solving one of the equations for one variable, then substituting that expression into the other equation to create an equation with only one variable. This method is straightforward and can be done by hand, but it can be time-consuming and error-prone if there are many variables or the equations are complex. Substitution is most appropriate when one of the equations is already solved for a variable, or when the equations involve simple linear or quadratic forms.

Elimination involves adding or subtracting the equations to eliminate one of the variables. This method is efficient and can be done systematically, but it can be confusing if the equations are not balanced or there are many variables. Elimination is most appropriate when the coefficients of one of the variables are equal or opposite in both equations, or when there are many equations and variables.

In general, the choice of method depends on the specific equations and the preferences of the solver. Graphing is a good method to use when the equations are simple and easy to plot, substitution is useful when one equation is already solved for a variable or the equations involve simple forms, and elimination is a good choice when the equations have balanced coefficients or there are many equations and variables to consider. It is important to keep in mind the strengths and weaknesses of each method and to choose the most appropriate method based on the specific situation.

The vertex and range of the function y =  |4x + 8| - 1 are (- 2, - 1) and  

{y : y ∈ R} - [ - 3, 0) respectively.

We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.

In piecewise terms  | x | = x for x ≥ 0 and | x | = - x for x < 0.

An absolute value function y = a|x - h| + k has vertex (h, k).

So, the absolute value funcion y = |4x + 8| - 1  has a vertex (- 2, - 1).

y = |4x + 8| - 1.

y + 1 = |4x + 8|.

y + 1 = (4x + 8) Or y + 1 = (4x + 8).

y + 1 = 4x + 8 Or y + 1 = - 4x - 8.

y = 4x + 7 Or y  - 4x - 9.

So, The range of the function is all real numbers except and below the vertex which is {y : y ∈ R} - [ - 3, 0).
