Answer:

Mean is 69.8

Median is 77

Range is 54

Step-by-step explanation:

Mean is all numbers added up, then divided by the amount of numbers.

Median is the middle number of all numbers (To find this you put all numbers in order from least amount to highest amount, then you find the most center number of the rest).

Range is the highest number subtracted from the lowest number.

Answer:

Mean:  69.8

Range:  54

Median:  77

Step-by-step explanation:

The mean is the average of the numbers.  The range is the largest number minus the smallest number.  The median is the middle number.

The mean is 69.8.

[tex]\frac{45 + 83+45+77+99}{5} \\\frac{349}{5}\\69.8[/tex]

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.

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.

The required age for Emma and her sister is 26 years and 15 years respectively.

Given that,
The sum of Emma’s age and her sister's age is 41 years. Emma is 11 years older than her sister.

The problem given is of arithmetics.

Let the age of Emma be x and her sister be y.

The sum of Emma’s age and her sister's age is 41 years.
x + y = 41   - - - - - - (1)

Answer: A = 72

B = 108

Step-by-step explanation:

 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.

The diameter of a circle with a circumference of 11.4mm is approximately 3.63mm when rounded to three significant figures. The formula for calculating the diameter is D = C/π, where C is the circumference.

The student is asking how to find the length of the diameter of a circle if the circumference is given as 11.4mm. To find the diameter, we can use the formula for the circumference of a circle, which is C = πD, where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14159, and D is the diameter. Rearranging the formula to solve for the diameter, we get D = C/π.

Substitute C with 11.4mm into the equation:

D = 11.4mm /π

Using a calculator:

D ≈ 11.4mm / 3.14159

D ≈ 3.63mm (rounded to three significant figures)

Therefore, the diameter of the circle is approximately 3.63mm when rounded to three significant figures.

Answer:

375 seconds.

Step-by-step explanation:

Step 1

The first step is to find the Circumference of the paddle.

The Circumference of a paddle = Circumference of a circle = 2πr or πD

Where D = Diameter of the circle or Diameter of the paddle

In the question above,

Diameter of a paddle = 8 feet

Circumference of the paddle= πD

= π × 8

= 25.132741229 feet

Step 2

We have to find out first, the time it would take for the paddle to complete one revolution.

This is calculated using the formula:

Time(t) = distance travelled ÷ Speed travelled by the fins along the outer edge of the paddle

In the question,

Speed travelled by the fins along the outer edge of the paddle = 6.7 feet per second

It is important to note that the distance travelled is = Circumference of the paddle = 25.132741229 feet

Time taken to complete one revolution = 25.132741229 feet ÷ 6.7 feet per second

Time taken to complete one revolution. = 3.7511554073 seconds

Approximately = 3.75 seconds.

Step 3

If , 1 full revolution of the paddle takes = 3.75 seconds

100 revolutions =

100 × 3.75 seconds

= 375 seconds.

Therefore, it takes the paddle wheel 375 seconds to complete 100 full revolutions.

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.

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 .

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:

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:

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

The signs of x and y depend on the quadrant the point is located in, guiding whether each value is positive or negative.

The signs of the values of x and y depend on which side of the origin point P lies. When a point is in the first quadrant, both x and y values are positive.

In the second quadrant, x is negative, and y is positive.

In the third quadrant, both x and y are negative, while in the fourth quadrant, x is positive, and y is negative.
