Answer:

291

Step-by-step explanation:

Think of a triangle with vertices D (Dublin), L (London), and P (Paris).

Let x = DL

Let y = LP

Let z = DP

"The distance from Dublin to London is 78 more miles than the distance between London and Paris."

DL = LP + 78

x = y + 78

If the distance between Dublin and Paris is 504 miles, including the stop in London.

DL + LP = 504

x + y = 504

x = y + 78

x + y = 504

y + 78 + y = 504

2y = 426

y = 213

x = y + 78

x = 213 + 78

x = 291

Answer:

The distance between London and Paris is 213 miles, and the distance between Dublin and London is 291 miles.

Step-by-step explanation:

Let's assign variables to the unknown distances:

Distance from London to Paris = x

Distance from Dublin to London = x + 78

According to the given information, the distance between Dublin and Paris, including the stop in London, is 504 miles. Using these values, we can set up the equation:

Distance from Dublin to London + Distance from London to Paris = 504

(x + 78) + x = 504

Combining like terms:

2x + 78 = 504

Subtracting 78 from both sides:

2x = 426

Dividing both sides by 2:

x = 213

Therefore, the distance between London and Paris is 213 miles, and the distance between Dublin and London is 213 + 78 = 291 miles.

Answer:

+9.4 to the nearest tenth

Step-by-step explanation:

(-4, 5) (4, 0)

Refering to the x-coordinates and the y-coordinates of these two points, we see that x changes from -4 to 4, a change of 8, which forms the horizontal leg of a right triangle.  Simultaneously, y changes from 5 to 0, a change of 5, which forms the vertical leg.  Now use the Pythagorean Theorem to determine the length of the hypotenuse of this triangle; this hypotenuse is the distance between the two points:

distance = +sqrt(8^2 + 5^2) = +sqrt(64 + 25) = + sqrt( 89) = +9.43 to the nearest hundredth and +9.4 to the nearest tenth.

Answer:

Step-by-step explanation:

If I found the mean, the answer would be:

3+ 4+4+4+5+6+7+23= 56

56/ 8 = 7

If I found the average value using the median, the answer would be 4.5.

In this set of data, the anomaly is 23 as it is much higher than the other numbers.

The median is more accurate because it find the more ‘central’ number and is not affected as greatly with anomalies whereas the mean is affected greatly with anomalies as it raises the value significantly.

Therefore, the median is better to work out the average in this set of data.

The probability that one of the scores in the sample is less than 1484 is 0.2437 .

a)Given that mean u = 1403

standard deviation σ = 200

sample size n = 32

P(x>1484) = P(X-u/σ > 1484-1403/200)

                = P (z > 0.405)

P(x>1484) = 0.2437 .

hence the probability that one score is greater than 1484 is 0.405 .

b) Now we have to find the average of the scores of 48 samples.

P(x>1484)

= P(x-μ/ σ/√n> 1484-1403 /200/√48)

= P(z>2.805.)

Now we will use the normal distribution table to calculate the p value to be 0.002516.

p-value = 0.0025

Normal distributions are very crucial to statistics because not only they are commonly used in the natural and social sciences but also to describe real-valued random variables with uncertain distributions.

They are important in part because of the central limit theorem. This claim states that, in some cases, the average of many samples (observations) of a random process with infinite mean and variance is itself a random variable, whose distribution tends to become normal as the number of samples increases.

Answer: 834 days

Step-by-step explanation:

The tank will be half full when it has lost 100 L.

Convert that to milliliters so that it can be compared with the loss rate:

1 l = 1,000 ml

100 l = 100 * 1,000

= 100,000 ml

The rate of loss is 120 ml per day. To lose 100,000 ml, the leak would have to have been going on for:

= 100,000 / 120

= 833.3

= 834 days (less than half full)

If Kevin deposits $4000 into an account that pays simple interest at an annual rate of 5%, $1,000 is the total interest that Kevin will earn after 5 years if he makes no withdrawals.

Simple interest refers to the interest that is calculated on the original amount or the principal. Simple interest is calculated by:

Interest = P * r * t

where P is the principal

r is the rate of interest (in decimal)

t is the time

Given in the question,

P = $4000

r = 5% = 0.05

t = 5 years

Interest = 4000 * 0.05 * 5

= $1,000

Interest earned by Kevin after 5 years is $1,000.

Because studies used in a meta-analysis have typically used different statistical tests, a statistic called effect size is used to put all the results into a common scale.

A meta-analysis is a statistical approach used to synthesize the results of several studies. It is a quantitative study of studies. In other words, it is a method that uses statistical analysis to incorporate the results of multiple clinical studies, which helps to obtain a more precise and reliable estimate of the impact of the intervention.

Effect size is used to combine all the results of the different studies into a common scale because each study might use a different statistical test that is not directly comparable to other studies.What is effect size?Effect size is a numerical value that describes the magnitude of the difference between two groups in a study. It allows researchers to compare the findings from different studies that might use different measurement instruments.

A large effect size implies a significant difference between the two groups in a study. Conversely, a small effect size indicates that there is no meaningful difference between the groups. Effect size is calculated as the standardized difference between the means of two groups divided by their standard deviation (Cohen’s d).

123,400 in scientific notation is 1.234 × 10^5. Alternatively, in standard form, 123,400 remains the same as 123,400.

In scientific notation, a number is expressed as the product of a coefficient and a power of 10. The coefficient is typically a decimal number between 1 and 10, and the power of 10 indicates how many places the decimal point must be shifted.

For the number 123,400, we can express it in scientific notation as 1.234 × 10^5. Here's how:

1.234 is the coefficient, which is obtained by moving the decimal point one place to the left from the original number (123,400).

10^5 represents the power of 10. Since we moved the decimal point five places to the left to obtain the coefficient, the power of 10 is 5.

So, in scientific notation, 123,400 = 1.234 × 10^5.

On the other hand, in standard form, the number remains the same as 123,400. Standard form simply represents the number without any exponential notation or powers of 10.

Therefore, whether expressed in scientific notation (1.234 × 10^5) or standard form (123,400), the numerical value of 123,400 remains unchanged.

Step-by-step explanation:

Use pythagorean theorem to solve the center height of Sam’s tent.

The center height of the triangle or Sam's tent is given by AB = 4 feet

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the base of the triangle is BC = 3 feet

The hypotenuse of the triangle is AC = 5 feet

And , the triangles share a common height

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

So , the height of the triangle AB = √ ( AC )² - ( BC )²

On simplifying , we get

The height of the triangle AB = √ ( 25 ) - ( 9 )

The height of the triangle AB = √16

The height of the triangle AB = 4 feet

Hence , the height of the triangle is 4 feet
