Answer: The length of the side of a square is 20 cm.

Step-by-step explanation:

Part 1: Find the x

First, you know that all sides of a square are equal, therefore, these two equations should be equal.

6x - 1 = 4x+6

Now, you simplify.

You would move whichever like term you want (either 6x over to the side of 4x (or vice versa) or -1 to the side of the 6 (or vice versa)

In my case, I will move 4x over to the other side.

Now I have:

6x - 4x -1 = 6

You can subtract like terms, in this case 6x and 4x:

2x - 1 = 6

Now you do the same, just with the constant numbers.

You would move over the -1 to try isolate the variable. (Keep in mind that the sign (positive or negative) changes when you move it to the other side.

2x = 6 +1

2x = 7

Then, you want to leave x by itself, so you have to divided 2x by 2. What you do to that side, you have to do to the other side.

2x/2 = 7/2

x = 3.5

Part 2: Plugging x into the equation

Now, since you have to x, you have to put it in any of the equations. Keep on mind it doesn’t matter, since both sides are the same anyway.

I‘m going to use the side 6x -1.

You now have to subsitute 3.5 for the x.

You now have:

= 6 (3.5) -1

= 21 -1

= 20

Therefore, your side is equal to 20 cm.

First, let's pick two pairs of coordinates from the table.

I picked (-3,6) and (1,-2).

Now, let's find the slope of the two coordinates. We are going to use the rise over run method.

-2 -6 /1 - -3 = -8/4

-8/4 = -2

The Empirical Rule is being used to calculate the height distribution for the male students at a school. Based on the mean height of 71 inches and standard deviation of 2.5 inches, the height interval that represents the middle 95% of the male heights at this school is approximately from 66 to 76 inches.

In the context of this question, we're using statistics, specifically the Empirical Rule, to find a range that represents the middle 95% of heights for the male students. The Empirical Rule states that, in a normal distribution:

Here, the mean height is 71 inches and the standard deviation is 2.5 inches, so applying the Empirical Rule- two standard deviations from the mean would capture about 95% of the heights:

Lower limit = Mean - 2(Standard Deviation)
= 71 - 2(2.5) = 66 inches

Upper limit = Mean + 2(Standard Deviation)
= 71 + 2(2.5) = 76 inches

So the height interval that represents the middle 95% of heights for the males at this school is 66 to 76 inches.

Using the empirical rule and a normal distribution with a mean of 71 inches and a standard deviation of 2.5 inches, the middle 95% interval of male heights is between 66 inches and 76 inches.

The student from the all-boys school is asking about an application of the empirical rule in statistics, which is useful for understanding data that follows a normal distribution. To find the interval that represents the middle 95% of heights, we apply the empirical rule, which states that 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations. Since we are interested in the middle 95%, we calculate the interval by subtracting and adding two standard deviations from the mean.

Calculation steps:

Therefore, the middle 95% of the males heights from this school fall between 66 inches and 76 inches.

Answer:

Reflecting over the x-axis and then reflecting over the line y = x.  

Step-by-step explanation:

A rotation 90° counterclockwise will map every point (x, y) to (-y, x).

Since the x- and y-coordinates are switched, this is not a reflection across the x-axis followed by a reflection across the y-axis.

Since the y-coordinate is negated and the x- and y-coordinates are switched, this is not a translation.

Reflecting across the x-axis will negate the y-coordinate, giving us (x, -y).  Following this with a reflection across y=x will switch the coordinates giving us (-y, x).  This is the correct transformation.

Answer:

95% confidence interval for the actual average amount of time the entire population can hold their breath under water is between 72.55 and 72.85.

Step-by-step explanation:

Confidence Interval for the population mean is basically an interval of range of values where the true population mean can be found with a certain level of confidence.

Mathematically,

Confidence Interval = (Sample mean) ± (Margin of error)

Sample Mean = 72.7

Margin of Error is the width of the confidence interval about the mean.

It is given mathematically as,

Margin of Error = (Critical value) × (standard Error of the mean)

Critical value will be obtained using the t-distribution. This is because there is no information provided for the population mean and standard deviation.

To find the critical value from the t-tables, we first find the degree of freedom and the significance level.

Degree of freedom = df = n - 1 = 150 - 1 = 149

Significance level for 95% confidence interval

(100% - 95%)/2 = 2.5% = 0.025

t (0.025, 1499) = 1.975 (from the t-tables)

Standard error of the mean = σₓ = (σ/√n)

σ = standard deviation of the sample = 0.92

n = sampling size = 150

σₓ = (0.92/√150) = 0.0751176854 = 0.07512

95% Confidence Interval = (Sample mean) ± [(Critical value) × (standard Error of the mean)]

CI = 72.7 ± (1.975 × 0.07512)

CI = 72.7 ± 0.1483574288

95% CI = (72.55, 72.85)

95% Confidence interval = (72.55, 72.85)

Answer:

L. W = 60. 30.

Step-by-step explanation:

Perimeter = 2L + 2W where W = width and L = the length, and L = 2W.

We have the following system:

2L + 2W = 180

L = 2W

Substituting L = 2W in the first equation we have:

2(2W) + 2W = 180

4W + 2W = 180

6W = 180

W = 180/6 = 30.

So L = 2*30 = 60.

We have been given that the circular opening of an ice cream cone has a diameter of 7 centimeters. The height of the cone is 10 centimeters. We are asked to find the volume of the ice-cream cone.

We will use volume of cone formula to solve our given problem.

[tex]V=\frac{1}{3}\pi r^2 h[/tex], where

r = Radius of cone,

h = Height of cone.

We know that diameter is two times the radius, so radius will be half of diameter that is [tex]r=\frac{7}{2}[/tex].

[tex]V=\frac{1}{3}\pi\cdot (\frac{7}{2})^2\cdot 10[/tex]

[tex]V=128.2817[/tex]

[tex]V\approx 128.3[/tex]

Therefore, the volume of the cone would be approximately 128.3 cubic cm.

Answer:

A good combination will be equal to or greater than 80 ft³. Example

r = 3 ft

h = 5 ft

Step-by-step explanation:

The volume of a cylinder  = πr²h

Jeff is planning on building a cylindrical water tank that has a capacity of no less than 80 ft³.  This means he want the volume of the cylindrical tank to be equal to or greater than 80 ft³(volume ≥ 80 ft³). The combinations of radius and height should be equal to or greater  than 80 ft³ when they are inserted in the volume formula of a cylindrical water tank.

For example

volume = πr²h

r = 2 ft

h = 5 ft

volume = πr²h

volume = 3.14 × 2² × 5 = 62.8  ft³ is not a good combination of base radius and height because the volume is less than 80 ft³.

A good combination will be equal to or greater than 80 ft³. Example

r = 3 ft

h = 5 ft

volume = πr²h

volume = 3.14 × 9 × 5 = 3.14 × 45 =  141.3  ft³ is a good combination of radius and height .

Answer:

The perimeter would be 60 units; Option B

Step-by-step explanation:

~ Let us consider this problem. We know that tangent segments are congruent to one another provided they are from one endpoint. According to that, we would note that several segments are congruent to one another...  ~

1. All the tangent segments that "sprout" from one vertex in this plane onto the circle circumscribed in this triangle are congruent, as noted before. According to that the side of the length 18 units has one part equivalent to 8.7 units.

2. With that being said the other part of the side with length 18 units, would be 18 - 8.7 = 9.3 units. Respectfully the side with length of 21.3 units has a part that is congruent to 9.3, by tangent ≅. This other part of the side with 21.3 units now = 21.3 - 9.3 = 12 units. Similarly the side with 8.7 as a part of it, has the other part ≅ to 12 units, it's measure thus also being 12 units.

3. Let us see the measures we have at this point. The perimeter would be ⇒ 8.7 + 8.7 + 9.3 + 9.3 + 12 + 12 = 60 units

If the probability of an event is 0, it is impossible to happen, in contrast to an event with a probability of 1, which is certain to happen. Probability is measured between 0 (impossible event) and 1 (certain event), with a familiar example being a coin flip where each outcome (heads or tails) has an equal probability of 0.5.

If the probability of a chance event is 0, it is impossible for it to happen when compared to a chance event with a probability of 1, which is certain to happen. The concept of probability is expressed as a number between zero and one, inclusive. An event with a probability of 0 is not expected to happen at all, while an event with a probability of 1 is considered an absolute certainty. In contrast, if two events are mutually exclusive, the probability that they both happen at the same time is zero (P(A AND B) = 0). A familiar example involving probability is flipping a fair coin, where there's a 1/2 chance of getting heads, meaning that the outcome of getting either heads or tails are equally likely; each has a probability of 0.5.

The sum of the geometric sequence can be found by plugging the values into the formula S_n = a * (1 - r^n) / (1 - r) and calculating it using a graphing utility.

The question pertains to finding the sum of a geometric sequence using a graphing utility. The general formula to find the sum of a geometric sequence is S_n = a * (1 - r^n) / (1 - r) where S_n is the sum of the first n terms, a is the first term, r is the common ratio, and n is the number of terms. In your case, our first term a is 15, common ratio r is 5, and number of terms n is 6.

Now, you need to plug these values into the formula and compute the sum. Here's how: S_6 = 15 * (1 - 5^6) / (1 - 5). Solve this equation using your graphing utility to get the sum of the sequence. Remember to round off to three decimal places as needed.

The volume of the hemisphere with a radius of 9 centimeters is 1526.8 cubic centimeters.

To find the volume of the hemisphere with a radius of 9 centimeters, we use the formula for the volume of a sphere and then divide it by 2, because a hemisphere is half of a sphere. The volume V of a sphere is given by V = (4/3)πr³, where r is the radius.

Therefore, the volume of the hemisphere is V = ½ × (4/3)πr³. Plugging in the given radius:

V_hemisphere = ½ × (4/3)π × (9 cm)³

V_hemisphere = ½ × (4/3) × 3.1416 × 729 cm³

V_hemisphere = ½ × (4× 3.1416 × 243)

V_hemisphere = ½ × 3053.6288 cm³

V_hemisphere = 1526.8144 cm³

When rounded to the nearest tenth, the volume of the hemisphere is 1526.8 cm³.

 ANSWER. BBB

Step-by-step explanation:

Mrs. Jones gave candy bars to 80 children who were wearing costumes. The correct answer is option D.

The question is a classic example of a system of equations problem

Let's call the number of children with costumes x and the number without costumes y. We have two pieces of information that will help us solve for x:

The total number of children is 100, so x + y = 100.

The total amount of money spent on candy is $69, and since candy bars cost $0.80 and gummies cost $0.25, we can express this as 0.80x + 0.25y = 69.

We can solve this system of equations using substitution or elimination method.

Let's use substitution and express y in terms of x from the first equation: y = 100 - x.

Now we substitute this into the second equation:

0.80x + 0.25(100 - x) = 69

0.80x + 25 - 0.25x = 69

0.55x = 44

Solving for x gives us x = [tex]\frac{44}{0.55}[/tex]

Therefore, 80 children wearing costumes were given candy bars by Mrs. Jones. The correct answer is D.
