It would take 5040 cubic inches of water to completely fill the aquarium.

We know that the formula for the volume of cuboid :

V = length × width × height

Let us assume that l represents the length of the aquarium, w represent the width and h represents the height.

Here, l = 20 inches

w = 14 inches

and h = 18 inches

Using the formula for the volume of cuboid, the volume of aquarium would be,

V = l × w × h

V = 20 × 14 × 18

V = 5040 cu.in.

Therefore, it would take 5040 cu.in. of water.

Step-by-step explanation:

The area of the circular figure which is the top of a can drink with a diameter of 3 inches is about 7.065 square inches

A circular figure is one that has no edges or sharp corners, and which is essentially round (in the form of a disc or the path described by rotary motion) in shape.

A circular object occupies the largest area per diagonal compared to other regular shapes, as the circular inscribes other regular shapes within its circumference.

The shape in the figure is a circle

The diameter of the circle, D = 3 in.

The formula for finding the area of a circle, A, for which the diameter is presented as follows;

Area of the circle, A = π·D²/4

The approximation of the value of π to be used are 3.14 or 22/7

The area is obtained by plugging in the values of D and π in the formula for the area of a circle as follows;

The area of the figure is; A = 3.14 × 3²/4 = 7.065

The value of x based on the given diagram is 8.

The correct answer choice is option B.

Supplementary angles are two angles which add up to 180°

Let

The angle opposite (9x - 19)° = y°

Angle y° and 127° are supplementary angles

So,

y + 127 = 180

y = 180 - 127

y = 53°

Opposite angles are equal;

Then,

(9x - 19)° = 53°

9x - 19 = 53

9x = 53 + 19

9x = 72

x = 72/9

x = 8

Ultimately, x is given as 8

Step-by-step explanation:

Answer:

0.969

Step-by-step explanation:

use the z-score formula to convert the values.

z = (X - υ) / σ

where X is the test statistic, υ is the mean, σ is the standard deviation.

z = (18 - 31) / 7

= -1.857

area in z-score table (this is area to left of <18) is 0.0314.

Andrew needs to score 99 on his fifth science test in order to have an average of 93 across all five tests.

To find out what score Andrew needs to earn on his fifth science test, we can use the concept of averages. The average of a set of numbers is calculated by adding up all the numbers and then dividing the sum by the total number of values.

Andrew has already taken four science tests, and their scores are given as 87, 89, 97, and 95. To calculate the average, we add up these four scores: 87 + 89 + 97 + 95 = 368.

Now, we need to consider the fifth test score that Andrew needs to achieve. Let's call it x. To have an average of 93 across all five tests, we need to divide the sum of all the scores (including the fifth test score) by 5 (the total number of tests): (368 + x) / 5 = 93.

We can solve this equation for x by isolating it on one side. Multiplying both sides by 5 gives us 368 + x = 465. By subtracting 368 from both sides, we find x = 465 - 368 = 97.

Therefore, Andrew needs to score 97 on his fifth science test to have an average of 93 across all five tests.

Here the equation given to us is,

\({\blue{\boxed{\pink{y = 2x + 1}}}}\)

Now what we have to do is, we have to put the value of x in brackets () in both the equations . Why we have to put value of x in a bracket?

This is because 2 is being multiplied by the variable x. So let's solve the equations

a) When x = 5, what is the value of y?

Put the value of x here

y = 2x + 1

y = 2(5) + 1

y = 10 + 1

A ratio is an ordered pair of numbers a and b written as a/b where b is not equal to zero.

if the number of women in the social club is 595 then the number of men in the social club is 425.

A ratio is an ordered pair of numbers a and b written  as:

a / b where b does not equal 0.

A proportion is an equation in which two ratios are equal to each other.

We have,

The ratio of men to women:

= 5:7

= 5/7

Let,

The number of men = 5x

The number of women = 7x

Now,

If the number of women = 595

We have,

7x = 595

Multiplying both sides by 5/7 we get,

5/7 x (7x) = 5/7 x 595

5x = 5/7 x 595

5x = 5 x 85

5x = 425

This means if there are 435 men in the social club if the number of women is 595.

Thus if the number of women in the social club is 595 then the number of men in the social club is 425.

If we want to provide a 99% confidence interval for the mean of a population, the confidence coefficient will be 0.99. This means that there is a 99% probability that the true population mean falls within the calculated interval.

The confidence coefficient for a confidence interval represents the level of confidence we have in our estimate.

In the case of a 99% confidence interval, the confidence coefficient is 0.99. This means that we are 99% confident that the true population mean falls within the calculated interval. The confidence coefficient is derived from the desired level of confidence, which is typically expressed as a percentage.

A higher confidence level corresponds to a larger confidence coefficient. In practical terms, a 99% confidence interval indicates that if we were to repeat the sampling process multiple times and construct 99% confidence intervals, approximately 99% of those intervals would contain the true population mean.

Given that the study was conducted using a sample of 513 bolts produced at a single facility when there is no bias resulting from data gathering procedures, broad inferences may then be drawn.

All bolts manufactured by that factory would be covered by the conclusion?

Due to the fact that bolts made in the same factory will follow the results of an analysis of a sample made up of bolts from the same factory. The finding or conclusion would therefore be applicable to all bolts produced in the same factory because the environment for experimentation and production is the same there while it may differ in other factories. Conclusions from the study may not apply to the bolts made by other companies as a result of this bias.

The candle will burn for approximately 197 more hours before melting entirely.

To calculate the mass lost by the candle after 3 hours of burning, we need to know the rate at which the candle burns. Let's assume the rate is given in grams per hour.

Once we have the rate, we can multiply it by the number of hours to find the mass lost. Let's say the rate is 0.5 grams per hour.

Mass lost after 3 hours = Rate × Time = 0.5 grams/hour × 3 hours = 1.5 grams.

Therefore, the candle lost 1.5 grams of mass after 3 hours of burning.

To estimate how much longer the candle will burn before melting entirely, we need to know the initial mass of the candle and the total mass it can lose before melting. Let's assume the initial mass is 100 grams and the maximum mass loss before melting is 80 grams.

Remaining mass = Initial mass - Mass lost = 100 grams - 1.5 grams = 98.5 grams.

Now, we can estimate the remaining burning time by dividing the remaining mass by the burning rate:

Remaining burning time = Remaining mass / Rate = 98.5 grams / 0.5 grams/hour = 197 hours.

The Spearman rank-order correlation coefficient is a measure of the direction and strength of the linear relationship between two ordinal variables.

Spearman's rank-order correlation is used when two variables are measured on an ordinal scale.

What is the Spearman Rank-Order Correlation Coefficient?

The Spearman Rank-Order Correlation Coefficient is a non-parametric statistical measure that estimates the relationship between two variables using ordinal data.

It evaluates the strength and direction of a relationship between two variables by rank-ordering the data.

The Spearman correlation coefficient, named after Charles Spearman, calculates the association between two variables' rankings.

The correlation coefficient ranges from -1 to +1. A value of +1 indicates that there is a perfect positive relationship between the variables, whereas a value of -1 indicates that there is a perfect negative relationship between the variables.

In contrast, a value of 0 indicates that there is no correlation between the variables.
