Final answer:

To find the equation of the line passing through two given points, we can use the slope-intercept form of a line. The equation of the line passing through (-5,2) and (9,0) is y = -1/7x + 9/7.

Explanation:

To find the equation of the line that passes through the points (-5,2) and (9,0), we can use the slope-intercept form of a line, y = mx + b. First, we need to find the slope (m) of the line. The slope is given by the formula m = (y2 - y1)/(x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. Plugging in the values, m = (0 - 2)/(9 - (-5)) = -2/14 = -1/7.

Next, we can choose one of the points and plug in its coordinates along with the slope into the equation y = mx + b to solve for b. Let's choose the point (-5,2): 2 = (-1/7)(-5) + b. Simplifying the equation, 2 = 5/7 + b. Subtracting 5/7 from both sides, 2 - 5/7 = b. Getting a common denominator, 14/7 - 5/7 = b. So, b = 9/7.

Finally, we can substitute the values of m and b into the equation y = mx + b to get the equation of the line: y = -1/7x + 9/7.

Answer: C

The middle values are both 3, so the median is 3.

Option C is the correct answer.

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

To find the median of the number of times a teenager is reminded to do chores a week, we need to arrange the responses in order from smallest to largest, and then find the middle value.

From the bar graph, we can see that the number of reminders ranges from 0 to 5, and the frequencies are not evenly distributed.

To determine the median, we need to count the total number of responses and find the middle value.

The total number of responses is:

2 + 5 + 8 + 14 + 7 + 4 = 40

Since there are an even number of responses, we need to find the average of the two middle values.

The two middle values are the 20th and 21st values when we arrange the responses in order:

0, 0, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 5, 5

Final answer:

To evaluate a logarithm, use the calculator's log button for the common logarithm or calculate 10 raised to the power of the logarithmic value for the inverse log. Logarithmic properties simplify expressions by converting multiplication into addition and exponents into multiplication.

Explanation:

Understanding and Evaluating Logarithms

To evaluate a logarithm, one can use a calculator's log button to find the common logarithm, which is based on base 10. If you have a logarithm and wish to find the actual number it represents, you take the inverse log of the logarithm. This can also be expressed as 10 to the power of the logarithmic value.

For instance, to evaluate log(100), you would press the log button on your calculator and then enter 100. The result would be 2, since 10^2 = 100. If you have the logarithm value, say 3, and want to find the number it corresponds to, calculate 10^3, which equals 1000.

Furthermore, logarithmic properties can be used to simplify expressions and solve equations. If you take the log of two numbers being multiplied, you can add their individual logs. Additionally, taking the log of a number raised to an exponent allows you to move the exponent in front of the log, thus multiplying the exponent by the log of the number.

During the seventeenth century, the principle of the logarithm was developed by Napier. Logarithms transform multiplication into addition, which simplifies many computations, like using antilogarithms and slide rules for multiplication.

Answer:

80%

Step-by-step explanation:

If there are 400 people total and 80 of them have coupons, then 320 people don’t have coupons. Divide 320 by 400 and you will get 0.8, which is 80%.

The required  percentage of the customers not using coupon is 80%.

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

Given that,

The total number of customers is 400.

And, those using coupon are 80.

Then, number of customers not using coupon are 400 - 80 = 320

Thus, the percentage of the customers not using coupon is given as,

320/400 × 100

= 8/10 × 100

= 80%

Hence, percent of the customers do not use a coupon is 80%.

Bo teaches 16 classes per week and Erica teaches 20 classes per week.

To find out how many yoga classes Bo and Erica each teach per week, we can set up a system of equations based on the given information.

Let B represent the number of classes Bo teaches per week. Let E represent the number of classes Erica teaches per week.

According to the problem, the total number of classes taught by Bo and Erica is 36:

Equation 1: B + E = 36

Also, we know that Erica teaches 12 fewer than twice as many classes as Bo:

Equation 2: E = 2B - 12

We can substitute the expression for E from Equation 2 into Equation 1:

B + (2B - 12) = 36

Simplify and solve for B:

So, Bo teaches 16 classes per week. Now we can find out how many classes Erica teaches by substituting B back into Equation 2:

E = 2(16) - 12

E = 32 - 12

E = 20

Therefore, Erica teaches 20 classes per week.

Thus, Bo teaches 16 classes per week and Erica teaches 20 classes per week.

A only (2,3)

Step-by-step explanation:

If you graph it or plug it into Desmos that can also help

The ordered pair (2,3) is a solution to the equation y-3=5(x-2), but the ordered pair (3,2) is not. Therefore, the correct answer is option A: Only (2,3).

In this Mathematics problem, we are asked to find which ordered pair is a solution to the equation y-3=5(x-2). An ordered pair is written in the form (x, y), so we'll test each option to see which one, if any, is a solution to the equation.

Let's start with option A, (2,3). If we substitute x with 2 and y with 3, we will have 3-3 = 5(2-2), which simplifies to 0 = 0. This equation is true, so the ordered pair (2,3) is a solution.

Next, we'll look at option B, (3,2). If we substitute x with 3 and y with 2, we will have 2-3 = 5(3-2), which simplifies to -1 = 5. This equation is not true, so the ordered pair (3,2) is not a solution.

Option C suggests that both (2,3) and (3,2) are solutions, but we've already established that (3,2) is not a solution to the equation.

So, based on our calculations, the correct answer is option A: Only (2,3) is a solution.

Answer:

56,000.0

Step-by-step explanation:

The number 6 is in the nearest thousand. To round, you look at the number in front of the number you are trying to round and decide if that number is higher or lower than five. If the number is higher than 5, round up to the next highest number. If the number is lower than 5, the number stays the same.

Final answer:

To round 56,291.8 to the nearest thousand, observe the hundreds digit; it's 2, less than 5, so we keep 56,000 and replace subsequent digits with zeros, giving a rounded figure of 56,000.

Explanation:

To round 56,291.8 to the nearest thousand, we need to look at the hundreds place, which is 2 in this case. Since this is less than 5, we don't round up the thousands place. Therefore, we keep the number 56,000 as it is without increasing the thousand's value. However, since we are rounding to the nearest thousand, we replace the hundreds, tens, ones, and decimal places with zeros, resulting in the final rounded number being 56,000.

Answer:

1.42π rad

Step-by-step explanation:

Principal value are known to be the largest value that can be equivalent to the trigonometry expression given.

Given

θ = arctan (3.7)

θ = 74.9°

The principal value of the angle can be found in the 3rd quadrant.

In the third quadrant, the angle gotten will become 180° + 74.9°

= 254.9°

Converting to radians

Since πrad = 180°

x = 254.9°

180x = 254.9π

x = 254.9π/180

x = 1.42π rad

The principal value of the angle is 1.42π rad.
