The long division of 16 divided by 13 is shown below
What is long division?Decimal numbers can also be divided into equal groups using long division. It goes through the same motions as long division, which are to divide, multiply, remove, add back in, and repeat, or discover the remainder.
The division of two numbers can be calculated using the following formula:
Dividend Divisor = Quotient + Remainder. The number that is being divided in this case is known as the dividend. The number that divides the number (dividend) into equal parts is known as the divisor.
Given:
16 divided by 13
Now, here the dividend= 16 and divisor= 13
So, the division is

Answer:
Total income earn = $422.5
Step-by-step explanation:
Given:
Earning per hour work = $10
Total hour = 40
Commission = 0.5% on sales
Total sales = $4,500
Find:
Total income earn
Computation:
Income from hour work = $10 x 40
Income from hour work = $400
Total commission = 0.5% x sales
Total commission = 0.5% x $4,500
Total commission = $22.5
Total income earn = $400 + $22.5

The correct answer is E. increase, more people will use buses, and buses are greater producers of carbon emissions than cars.
An increase in the gas tax in the United States to the level of European countries would have implications for carbon emissions. If the gas tax is increased.
It would likely result in more people choosing alternative modes of transportation, such as buses, which are known to be greater producers of carbon emissions compared to cars. Therefore, the increase in the gas tax could lead to an unintended consequence of higher carbon emissions.
This highlights the complex relationship between taxes, transportation choices, and environmental impact, emphasizing the need for comprehensive policies that consider the broader implications of such changes.

Which number best approximates the population as a single digit times a power of 10
The population of New York City in 2013, which is approximately 8,406,000 people, can be approximated as 8.4 million. This represents a single digit (8) multiplied by a power of 10 (million).
When we approximate the population of New York City as 8.4 million, we are expressing the number in scientific notation, where the single digit is 8 and the power of 10 is 6 (million).
In scientific notation, a number is written as a decimal coefficient multiplied by a power of 10. The coefficient is typically chosen to be a single digit, which in this case is 8. The power of 10 represents the number of zeros that follow the coefficient, and in this case, it is 6 because we have "million," which corresponds to 6 zeros.
By approximating the population as 8.4 million, we are representing it as a single digit (8) multiplied by a power of 10 (million), which fulfills the criteria of being a population approximated as a single digit times a power of 10.

where R is the region in the first quadrant bounded by the ellipse 4x2 +9y2 = 1.
The region R in the first quadrant bounded by the ellipse \(4x2 + 9y2 = 1\) is a special type of ellipse. \((x^2)/(a^2) + (y^2)/(b^2) = 1\), where a is the semi-major axis and b is the semi-minor axis. The region R in the first quadrant bounded by the ellipse\(4x2 + 9y2 = 1\) has an area of π/6.
In the given equation, the value of a is 1/2 and the value of b is 1/3. This ellipse is vertically aligned and centred at the origin. Since the region is confined to the first quadrant, it means that both x and y are greater than 0. Therefore, the limits of integration for x and y are 0 to a and 0 to b respectively.
The equation of the ellipse can be rewritten as \(y = ±(1/3)√[1 - 4x^2]\).
The top half of the ellipse is \(y = (1/3)√[1 - 4x^2]\) and
the bottom half is\(y = - (1/3)√[1 - 4x^2]\).
Thus, the integral is: \(∫∫ R 1 dA = ∫0^1 ∫0^(1/3) 1 dy dx,\) which is equal to the area of the ellipse. After integrating, we get the value as (1/2)π(a)(b),
which is equal to \((1/2)π(1/2)(1/3) = π/6.\)

The type of hypothesis that predicts that any difference between groups is due to chance (therefore, there is no meaningful difference between groups) is called the null hypothesis.
The null hypothesis (H0) predicts that there is no difference between groups, and any differences between groups are caused by chance. The null hypothesis is frequently utilized in statistical analysis. It contrasts with the alternative hypothesis (H1), which predicts that there is a meaningful difference between groups. In a statistical analysis, the null hypothesis is examined to see if there is enough proof to reject it and accept the alternative hypothesis. If the null hypothesis cannot be rejected, it is considered to be the default hypothesis.

The term in the expression that represents Lan's typical average speed is:
d - 20.
How can we get the average speed?Let's assume that Lan's typical speed is denoted by s. Then, her speed in the construction zone would be one-third of s, or s/3.
To find Lan's total travel time for the day, we need to add the time it takes for her to travel 20 miles in the construction zone to the time it takes for her to travel the remaining distance at her typical speed. We can represent this as:
Total travel time = time in construction zone + time at typical speed
The time it takes for Lan to travel 20 miles in the construction zone can be calculated using the formula:
time = distance / speed
So, the time in construction zone would be:
time in construction zone = 20 / (s/3) = 60/s
The time it takes for Lan to travel the remaining distance at her typical speed would be:
time at typical speed = (total distance - 20) / s = (d - 20) / s
Substituting these values into the expression for total travel time, we get:
Total travel time = 60/s + (d - 20) / s
To find the term in the expression that represents his typical average speed, we need to look for the variable that is being divided by s. This is the term: d - 20
So, Lan's typical average speed is: s = (d - 20) / time at typical speed.
Thus, the term in the expression that represents Lan's typical average speed is: d - 20.

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1425 referee calls with the results that 412 of the calls were overturned. Women challenged 739 referee calls, and 221 of the calls were overturned. Use a 0.05 significance level to test the claim that men and women have equal success in challenging calls. Test the claim using a hypothesis test. Consider the first sample to be the sample of male tennis players who challenge referee calls and the second sample to be the sample of female tennis players that challenged referee calls. What are the null and alternative hypotheses for the hypothesis test.
Answer:
CI = (-0.0445, 0.0225)
there is no sufficient evidence to men and women have equal success in challenging calls
Step-by-step explanation:
Sample size for men; n1 = 1425
Number of success for men; x1 = 412
Sample size for women; n2 = 739
Number of success for women; x2 = 221
Significance level; α = 0.05
Sample proportion for men;
p1 = x1/n1 = 412/1425
p1 = 0.2891
Sample proportion for women;
p2 = x2/n2 = 221/739
p2 = 0.2991
From tables, z-score at significance level of 0.05 is 1.96.
Formula for margin of error is;
E = z√[(p1(1 - p1)/n1) + (p2(1 - p2)/n2)]
Plugging in the relevant values;
E = 1.96√[(0.2891(1 - 0.2891)/1425) + (0.2991(1 - 0.2991)/1425)]
E = 1.96 × 0.0170687
E = 0.0335
Coordinates of the confidence interval will be;
[(p1 - p2) - E], [(p1 - p2) + E]
[(0.2881 - 0.2991) - 0.0335], [(0.2881 - 0.2991) + 0.0335]
CI = (-0.0445, 0.0225)
This means that the confidence interval contains 0 since it's between (-0.0445 and 0.0225). Thus we can conclude that there is no sufficient evidence to men and women have equal success in challenging calls

Given: Dernea Gardening sells wheel barrows. A wheelbarrow costs $6. 94 to produce and it sells for $42. 50.The company employs two salespeople, each of whom earns a different commission per wheelbarrow sold as shown in the table below. A 3-column table with 2 rows. Column 1 is labeled Salesperson with entries Travis, Gary. Column 2 is labeled Sold with entries 36, 48. Column 3 is labeled Commission/Sale with entries 7 dollars and 50 cents, 10 dollars and 60 cents. The company's expenses last month, not counting production costs or commissions, totaled $524. 24. We have to determine the profit the company has made from the sales of wheelbarrows last month. Profit can be calculated as follows; Profit = Total revenue - Total expenses. We are given that a wheelbarrow costs $6.94 to produce, and it sells for $42.50. The profit from one wheelbarrow can be calculated as: Profit per wheelbarrow = Selling price - Cost price= $42.50 - $6.94 = $35.56. Now, we calculate the total revenue by multiplying the number of wheelbarrows sold by the selling price. The total revenue can be calculated as: Total revenue = (36 + 48) × $42.50= 84 × $42.50= $3,570.
To find the total commission paid to the salespeople, we use the commission per sale and the number of wheelbarrows sold. The total commission can be calculated as follows: Total commission = Travis's commission + Gary's commission= (36 × $7.50) + (48 × $10.60)= $270 + $508.80= $778.80. To calculate the total expenses, we are given that the expenses not counting production costs or commissions were $524.24. Therefore, the profit can be calculated as: Profit = Total revenue - Total expenses= $3,570 - ($524.24 + $778.80)= $3,570 - $1,303.04= $2,266.96. Hence, the option (d) is correct. The profit the company made from the sales of wheelbarrows last month was $2,266.96.
