The number that goes beneath the radical symbol is 40.

To find the distance between the two points (-4,3) and (2,5), you can use the distance formula:

distance = √[(x2 - x1)^2 + (y2 - y1)^2]

Plugging in the values, you get:

distance = √[(2 - (-4))^2 + (5 - 3)^2]

Simplifying the expression, you get:

distance = √[6^2 + 2^2]

Which simplifies to:

distance = √[36 + 4]

Simplifying further, you get:

distance = √40

So the distance between the two points is √40. The number that goes beneath the radical symbol is 40.

The probability that Sumit actually saw a shark is 1/36.

The area of mathematics known as probability deals with numerical representations of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an occurrence, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

According to the question, we can say

Let us assume that Sumit has actually seen 1 creature.

The probability that it is a Shark and Sumit reports it correctly = (1/8)(1/6) = (1/48)

The probability that it is not a Shark and Sumit claims that it is = (7/8)(5/6) = (35/48)

Therefore,

The probability that Sumit actually sees a Shark, given that he claimed to have seen one = [(1/8)(1/6)] / [(1/8)(1/6) + (7/8)(5/6)] = 1/36

Answer:

$4.40

Step-by-step explanation:

To find the cost of each coffee in dollars, you can use the inequality:

2.39 + 4c < 20

This inequality states that the total cost of the cookie and the four coffees is less than $20.

To solve for c, the cost of each coffee in dollars, you can start by combining like terms on the left-hand side of the inequality:

2.39 + 4c = 20 - 2.39

4c = 17.61

Then, divide both sides of the inequality by 4 to solve for c:

c = 17.61 / 4

c = $4.40

So, the cost of each coffee in dollars is $4.40.

The three numbers are 1) 6,6,5. Option A

Generally, To determine if three numbers can be the sides of a triangle, we can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

For cases of 1) 6,6,5:

6 + 5= 11, which is greater than 6, so these three numbers can be the lengths of the sides of a triangle.

For the case of 2) 3,10,7:

3 + 7= 13, which is not greater than 10,  so these three numbers cannot be the lengths of the sides of a triangle.

For the case of 3) 7,2,5:

5+ 2= 7, which is not greater than 7, so these three numbers cannot be the lengths of the sides of a triangle.

For the case of 4) 2,8,5:

2 + 5= 7, which is not greater than 8, so these three numbers cannot be the lengths of the sides of a triangle.

Therefore, the three numbers is 1) 6,6,5

Answer:

y = -X + 3

Step-by-step explanation:

X + Y = 3

Y = -X + 3 (in the form of Y = mX + c, where m is the gradient of the graph and c is the y intercept of the graph)

Through observation,

gradient = -1

y-intercept = 3

The equation with 'n' as the independent variable is m = -2n - 13.

To rearrange the equation so that n is the independent variable, you can start by moving all of the terms with n on one side of the equation and all of the other terms on the other side.

You can start by subtracting 1 from both sides of the equation to get

m = -2(n + 6) - 1.

Then, you can distribute the -2 on the right side of the equation to get

m = -2n - 12 - 1.

Finally, you can combine the constants on the right side of the equation to get m = -2n - 13.

Therefore, the equation with 'n' as the independent variable is m = -2n - 13.

Answer:

The percent error of the measurement is 6.7%

Step-by-step explanation:

The percent error of a measurement is a measure of how accurate the measurement is compared to the actual value. It is calculated using the following formula:

percent error = (measured value - actual value) / actual value * 100%

In this case, the measured value is 1.4 inches and the actual value is 1.5 inches. Plugging these values into the formula, we get:

percent error = (1.4 - 1.5) / 1.5 * 100% = -0.1 / 1.5 * 100% = -6.67%

This means that the measurement was off by 6.7% compared to the actual value.

It's important to note that a negative percent error indicates that the measured value is less than the actual value, while a positive percent error indicates that the measured value is greater than the actual value. In this case, the measured value of 1.4 inches is less than the actual value of 1.5 inches, so the percent error comes out to be negative.

d. The extra variability is caused by variations in the df value.

T-statistics are used to test hypotheses about the mean of a population when the standard deviation of the population is unknown and the sample size is small.

The t-distribution is similar to the standard normal distribution (z-distribution) but it has flatter tails and is more spread out. This extra spread is caused by the fact that the t-distribution is based on the sample size, which is reflected in the degrees of freedom (df) value.

The larger the sample size, the closer the t-distribution is to the standard normal distribution, and the more similar the t- and z- statistics will be.

In contrast to this, as the sample size decrease, the t-distribution becomes more spread out and t- statistics are therefore more variable than z-scores.

This increased spread means that t-statistics have a higher chance of falling into the tails of the distribution, which leads to a greater likelihood of a type I error (rejecting a true null hypothesis) or a lower power (failing to reject a false null hypothesis).

We talk about the term permutation when we have to make a selection and the order of the selection has been taken to be important. In that case the order bcd would be different from the order cbd.

Hence, we could be able to use the formula for the permutation of the colors that are in the box and we would have the result as the use of the formula;

P = n!/ (n - r)!

n in this case would be the number of the boxes that we have and we would thus have;

Using the Pythagorean theorem, the length of the third side is [tex]\sqrt{(\sqrt{5})^2-2^2}=1[/tex].

The resulting polynomial is 1.3t^3 - 0.2t^2 - 42t + 8.

To add the polynomials, you should line up the terms with the same degree.

For the first polynomial, the coefficient of the term with the highest degree is 1.3.

For the second polynomial, the coefficient of the term with the highest degree is 8.

Therefore, the term with the highest degree in the result will be 1.3t^3 + 8.

The next highest degree in the first polynomial is t^2, and the coefficient of this term is 0.4.

The next highest degree in the second polynomial is also t^2, and the coefficient of this term is -0.6.

Therefore, the term with the next highest degree in the result will be 0.4t^2 - 0.6t^2.

The next highest degree in the first polynomial is t, and the coefficient of this term is -24.

The next highest degree in the second polynomial is also t, and the coefficient of this term is -18.

Therefore, the term with the next highest degree in the result will be -24t - 18t.

So, the resulting polynomial is:

(1.3t^3 + 8) + (0.4t^2 - 0.6t^2) + (-24t - 18t)

= 1.3t^3 + 0.4t^2 - 24t + 8 - 0.6t^2 - 18t
