24.13

2755

12.75

0.151

Step-by-step explanation:

Given :

21.1 + 45.99 + 26.0 = 93.09

15.55 + 21.61 - 12.333 = 24.827

14 + 0.8 + 9.33 = 24.13

14.5 * 190 = 2755

5.1 * 2.5 = 12.75

0.15 ÷ 0.991 = 0.151

Answer:

The statement that is true about the given equation is that it has no solution. This can be seen by rearranging the terms on both sides of the equation and then solving for y. When we do this, we get:

3(-y + 7) = 3(y + 5) + 6

-3y + 21 = 3y + 15 + 6

-6y = -12

y = 2

However, when we substitute this value of y back into the original equation, we find that it does not satisfy the equation. This means that there is no value of y that can make the equation true, so the equation has no solution.

Step-by-step explanation:

The linear distance traveled in one revolution of a wheel can be calculated using the formula:

Circumference = π * Diameter

Given that the diameter of the wheel is 36 inches, we can substitute the value into the formula:

Circumference = π * 36 inches

Using an approximate value of π as 3.14159, we can calculate the circumference:

Circumference ≈ 3.14159 * 36 inches

Circumference ≈ 113.09724 inches

Therefore, the linear distance traveled in one revolution of a 36-inch diameter wheel is approximately 113.09724 inches.

Mountain Mack can carve 60 fishing lures and 50 duck decoys in a week.

Let's denote the number of fishing lures carved by Mountain Mack as "L" and the number of duck decoys carved as "D". Based on the given information, we can set up a system of equations: When Mountain Mack spends all his time carving fishing lures, he can  carve 60 lures in a week:

L = 60

When Mountain Mack spends all his time carving duck decoys, he can carve 50 decoys in a week:

D = 50

For every 10 duck decoys carved, Mountain Mack must give up 12 fishing lures:

12 * (D / 10) = L

Now, let's solve the system of equations to find the values of L and D.

From equation (3), we can simplify it as:

12 * (D / 10) = L

12D/10 = L

6D/5 = L

Substituting L = 60 into the equation above:

6D/5 = 60

Solving for D:

6D = 5 * 60

D = 300/6

D = 50

So, we find that D = 50, which matches the information given.

Now, substituting D = 50 into equation (2):

L = 6D/5 = 6 * 50/5 = 60

Therefore, L = 60, which also matches the information given. Hence, the values of L and D satisfy all the given conditions.

Answer:

7. To perform a t-test when the sample size is small, the sample must show no evidence of strong skewness and must contain no outliers.

Step-by-step explanation:

These are the two conditions required for performing a t test

- Sample Size: A small sample size can reduce the statistical power of a t-test, making it more challenging to detect significant differences between groups. Generally, a larger sample size is desirable to obtain more reliable and representative results.

- Skewness: Skewness refers to the asymmetry of the distribution of data. In a t-test, assuming normality of the data is important for accurate results. If the data exhibits strong skewness, the assumption of normality may be violated. In such cases, alternative non-parametric tests or transformations of the data may be more appropriate.

- Outliers: Outliers are extreme values that significantly differ from the rest of the data. They can have a disproportionate impact on the results of a t-test, particularly when the sample size is small. Outliers can distort the mean and affect the assumptions of normality and homogeneity of variance.

While the presence of skewness or outliers does not prohibit the use of a t-test with a small sample size, it is important to interpret the results with caution and consider alternative approaches if necessary. Robust statistical methods, such as non-parametric tests or bootstrapping, can be useful when dealing with non-normal or outlier-prone data, especially with small sample sizes. Additionally, visual inspection of the data distribution, such as through histograms or box plots, can help identify potential skewness or outliers.

The equation to predict how many hours, x, the second part of the trip will take is :x = (total distance - distance traveled in the first part) / average speed x = (125 - 75) / 50  x = 1

To predict how many hours, x, the second part of the trip will take, we can use the equation:

x = (total distance - distance traveled in the first part) / average speed

In this case, the total distance of the trip is 125 miles, and the distance traveled in the first part is the product of the average speed and the time taken for the first part, which is 50 miles/hour * 1.5 hours = 75 miles.

Substituting these values into the equation, we have:

x = (125 - 75) / 50

Simplifying the equation, we get:

x = 50 / 50

x = 1

Therefore, the equation to predict how many hours, x, the second part of the trip will take is:

x = (total distance - distance traveled in the first part) / average speed

x = (125 - 75) / 50

x = 1

This means that the second part of the trip will take 1 hour to complete after the bus stops to refuel.

Answer: The base area of the cube is 25 square units.

Step-by-step explanation: A cube has six square faces, all of which are identical. The base area of a cube refers to the area of one of these square faces.

The formula for the volume of a cube is:

V = s^3

where V is the volume of the cube and s is the length of one side of the cube.

If we know the volume of the cube is 125 cubic units, we can solve for the side length:

125 = s^3

Taking the cube root of both sides, we get:

s = 5

Therefore, each side of the cube has a length of 5 units. The area of one of the square faces of the cube is:

A = s^2

A = 5^2

A = 25 square units

So the base area of the cube is 25 square units.

Answer:

25 square units.

Step-by-step explanation:

If a cube has a volume of 125 cubic units, then the edge length of the cube is the cube root of 125:

edge length = ∛125 = 5

Since all sides of a cube are equal, the base of the cube is a square with sides of length 5 units. The area of a square is calculated by multiplying the length of one side by itself:

base area = 5 × 5 = 25 sq. units.

Therefore, the base area of the given cube is 25 square units.

As the level of significance increases, the probability of making a type II error decreases.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.

If the level of significance of a hypothesis test is raised from 0.05 to 0.1, the probability of a type II error will decrease.

Type II error occurs when we fail to reject a null hypothesis that is actually false. It is the probability of accepting a false null hypothesis. By increasing the level of significance, we are making it easier to reject the null hypothesis, which in turn decreases the probability of accepting a false null hypothesis.

Hence, as the level of significance increases, the probability of making a type II error decreases.

The objective of keyword bidding is to d. get the best ranking for the lowest cost.

Keyword bidding is a practice used in online advertising, specifically in pay-per-click (PPC) campaigns, where advertisers bid on specific keywords to display their ads in search engine results. The objective of keyword bidding is to achieve the best possible ranking for their ads while keeping the cost as low as possible.

Option (a), obtaining the most profitable domain name, is not related to keyword bidding. Domain names refer to the website address or URL and are not directly associated with keyword bidding.

Option (b), limiting the amount of money the firm spends on search marketing, is partially correct but not the primary objective. While controlling costs is important, the main goal of keyword bidding is to optimize the ranking and visibility of ads.

Option (c), always being ranked first, is not feasible for every advertiser. Search engine rankings are determined by various factors, including bid amount, quality score, and relevance. It is not guaranteed that an advertiser will always secure the top position.

If f'(x) exists and f(x_1) > f(x_2) for every x_1 < x_2, then the possible value for f'(x) is d) f'(x) = 0. The correct answer is d f'(x) = 0.

The given condition states that the function f(x) is strictly increasing, meaning that the values of f(x) are getting larger as x increases. In such a case, the derivative f'(x) measures the rate of change of f(x) with respect to x. If f'(x) is greater than zero, it implies that the function is increasing at that point.

However, since f(x_1) > f(x_2) for every x_1 < x_2, the function cannot be increasing at any point. Therefore, option b) f'(x) > 0 is not possible.

If f'(x) is less than zero, it would indicate that the function is decreasing at that point. However, since f(x_1) > f(x_2) for every x_1 < x_2, the function cannot be decreasing at any point either. Thus, option c) f'(x) < 0 is not possible.

Since the function is neither increasing nor decreasing, the only possible value for f'(x) is when it is equal to zero. In other words, the function f(x) must have a horizontal tangent line at every point. Therefore, the correct answer is d) f'(x) = 0.

then multiply

17/12×17/18=

286/216

2/3 + 3/4

= 2 × 4/3 × 4 + 3 × 3/4 × 3

= 8/12 + 9/12

= 8 + 9/12

= 17/12

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 4) = 12. In practice, it is enough to find the common denominator by multiplying the denominators: 3 × 4 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.

Add: 3/6 + 4/9

= 3 × 3/6 × 3 + 4 × 2/9 × 2

= 9/18 + 8/18

= 9 + 8/18

= 17/18

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 9) = 18. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 9 = 54. In the next intermediate step, the fraction result cannot be further simplified by canceling.

2 = 17/12 × 17/18

= 17 × 17/12 × 18

= 289/216

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(289, 216) = 1. In the next intermediate step, the fraction result cannot be further simplified by canceling.
