write an equivalent addition expression for
-3-(-5)

Answer: The bottom three: \(\frac{48}{-17}\), \(\frac{-48}{17}\), and -2 \(\frac{14}{17}\)

Step-by-step explanation:

     The first option is not because the numerator and denominator are flipped.

     The second option is not because this one is positive while the one given is negative.

     The third option is equivalent.

     The fourth option is equivalent.

     The fifth option is equivalent because - 48 / 17 = -2 \(\frac{14}{17}\) when turned into a mixed number.

Answer:

\(\frac{48}{-17}, \frac{-48}{17}, -2\frac{14}{17}\) (the last 3 options)

Step-by-step explanation:
As long as the negative is in either the numerator or the denominator (if it is in both then it is positive because the negatives cancel out), the entire fraction will be negative, so both \(\frac{48}{-17}\) and \(\frac{-48}{17}\) work as answers. The last option is just a simplified version of the fraction.

​

Step-by-step explanation:

In the given analogy "6:64::11:?", the two pairs of numbers are related to each other in some way.

To find the missing number, we need to determine the relationship between the first pair of numbers (6 and 64) and then apply the same relationship to the second pair of numbers (11 and ?).

One possible relationship between 6 and 64 is that 64 is the result of squaring 6 and multiplying the result by 2. In other words,

64 = 2 × 6^2

Using this relationship, we can find the missing number as follows:

? = 2 × 11^2

= 2 × 121

= 242

Therefore, the missing number that completes the analogy "6:64::11:?" is 242.

Answer:

\(x = \frac{13}{4} \)

Step-by-step explanation:

\(4(x + 5) = 6(2x - 1)\)

Expand the terms in the bracket

That's

\(4x + 20 = 12x - 6\)

Subtract 12x from both sides of the equation

\(4x - 12x + 20 = 12x - 12x - 6 \\ - 8x + 20 = - 6\)

Subtract 20 from both sides

\( - 8x + 20 - 20 = - 6 - 20 \\ - 8x = - 26\)

Divide both sides by - 8

\( \frac{ - 8x}{ - 8} = \frac{ - 26}{ - 8} \\ x = \frac{26}{8} \)

We have the final answer as

\(x = \frac{13}{4} \)

The probability of both rice and carrots being served with dinner is 23.4%.

The probability of Alvin's mother serving rice with dinner can be expressed using the formula P(Rice) = 0.78. This means that the probability of Alvin's mother serving rice with dinner is 78%. The probability of Alvin's mother serving carrots with dinner can be expressed using the formula P(Carrots) = 0.30. This means that the probability of Alvin's mother serving carrots with dinner is 30%. To calculate the combined probability of both rice and carrots being served with dinner, we can use the formula P(Rice and Carrots) = P(Rice) * P(Carrots) = 0.78 * 0.30 = 0.2340. This means that the probability of both rice and carrots being served with dinner is 23.4%.

(a) With 10 rectangles using left endpoints, 5 rectangles are contributing negative area values to the estimated net area. This means that the function is below the x-axis in those intervals.

The remaining 5 rectangles are contributing positive area values, as the function is above the x-axis in those intervals.

When using midpoints, the number of positive and negative rectangles may not be the same. It depends on the behavior of the function within each subinterval. The use of midpoints can result in a different distribution of positive and negative rectangles compared to using left endpoints.

(b) The error when using midpoints with 10 subintervals can be determined by calculating the difference between the estimated net area using midpoints and the actual net area.

To calculate the error, we need to evaluate the definite integral of the function over the given interval and subtract the estimated net area using midpoints.

Error = Actual Net Area - Estimated Net Area using Midpoints

Since the exact values are not provided, the specific error value cannot be determined without further information or calculations.

Using left endpoints with 10 rectangles, 5 rectangles contribute negative area values and 5 contribute positive area values.

To find the number of feet the pipe was lifted, divide the total work (72 foot-pounds) by the weight of the pipe (24 pounds). This gives you 3 feet, which is the answer to your question.

The domain of the function is a semicircle with a radius of 5 and centered at the origin, where y is non-negative.

The domain of a function is the set of all possible input values for which the function is defined. In this case, the function is defined as:

\(f(x,y) = \sqrt{y} + \sqrt{[25 - x^2 - y^2} ]\)

To find the domain of this function, we need to determine the values of x and y that would result in the function producing a real-valued output.

For the square root of y to be real, y must be non-negative. That is, y ≥ 0.

For the square root of [\(25 - x^2 - y^2\)] to be real, we must have:

\(25 - x^2 - y^2 \geq 0\\x^2 + y^2 \leq 25\)

This is the equation of a circle with radius 5 centered at the origin. Therefore, the domain of the function is the set of all points (x, y) that lie inside or on this circle and have y ≥ 0.

In interval notation, we can write:

Domain: {(x, y) |\(x^2 + y^2 \leq 25, y \geq 0\)}

To sketch the domain, we can plot the circle with radius 5 centered at the origin and shade the region above the x-axis. This represents all the valid input values for the function. The boundary of the domain is the circle, and the domain includes all points inside the circle and on the circle itself, but not outside the circle.

The actual area of the office space is 10.4175 square feet.

To find the actual area of the office space, we first need to convert the dimensions of the scale drawing from inches to feet.

15 inches = 15/12 feet = 1.25 feet
4 inches = 4/12 feet = 0.33 feet

Now we can use these measurements to find the actual area of the office space:
Length:
15 inches × 5 feet/inch = 75 feet

Width:
4 inches × 5 feet/inch = 20 feet

Actual length = 1.25 feet x 5 = 6.25 feet
Actual width = 0.33 feet x 5 = 1.67 feet

Actual area = Actual length x Actual width
Actual area = 6.25 feet x 1.67 feet
Actual area = 10.4175 square feet

Therefore, the actual area of the office space is 10.4175 square feet.

Answer:

Mean: 8.27 minutes

Median: 8

Mode: 8

Range:  9

Step-by-step explanation:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

To find the median you would add up all of the numbers and divide by the number of numbers in the data set. The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median.

To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.

The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

The measures of the angles in the triangle are 20 degrees, 70 degrees, and 90 degrees.

Let's denote the measures of the angles as follows:

First angle: x

Second angle: 3x + 10

Third angle: x + (3x + 10)

According to the given information, the sum of the measures of the angles in a triangle is always 180 degrees. Therefore, we can write the equation:

x + (3x + 10) + (x + (3x + 10)) = 180

Simplifying the equation:

x + 3x + 10 + x + 3x + 10 = 180

8x + 20 = 180

8x = 180 - 20

8x = 160

x = 160 / 8

x = 20

So, the measure of the first angle is 20 degrees.

The measure of the second angle is 3x + 10 = 3(20) + 10 = 70 degrees.

The measure of the third angle is x + (3x + 10) = 20 + (3(20) + 10) = 20 + 70 = 90 degrees.

Therefore, the measures of the angles in the triangle are 20 degrees, 70 degrees, and 90 degrees.

The expected gain or loss of an experiment over the long run is called the expected value.

The expected value is the weighted average of all possible outcomes, where the weights are the probabilities of those outcomes occurring. It is calculated by multiplying each possible outcome by its probability of occurring and then adding up these products. The expected value can be used to make decisions and assess risk in various fields, including finance, economics, and gambling. If the expected value is positive, it means that, on average, the experiment will result in a gain, while a negative expected value indicates a loss.

A plausible lurking variable that could explain the cause and effect in the headline "Is Gluten the Culprit in Our Fight Against Obesity?" is overall diet.

It's possible that individuals who consume a diet high in gluten also consume a diet high in overall calories and processed foods, leading to weight gain and obesity. This would mean that it is not specifically gluten causing the obesity, but rather a combination of factors in the individual's diet.

A lurking variable is a variable that has a connection (e.g., may be correlated) with the response and the explanatory variable but is neither the explanatory variable nor the response variable.
