Solve and graph the inequality on a number line:
42>g+27

They filled bags that total 879 and the treats that did not fit are 4

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given here, total treats = 6157, and group them in bags with 7 each

now, we can write 6157 = 879×7+4

thus, on dividing 6157 by 7 we get the remainder as 4 and the quotient as 879

Hence, the bags of treats they filled is 879, and 4  treats were given to the groomer

P = ∫(i^2 dl / 6πε0 c^3) × a^2

where q is the charge, ε0 is the permittivity of free space, c is the speed of light, and a is the acceleration of the charge.

Now consider a small element of length dl around the ring through which the current i flows. The power radiated from this element can be written as

dP = (i^2 dl / 6πε0 c^3) × a^2

where a is the acceleration of the charge in the element due to the changing magnetic field.

The total power radiated from the entire ring is obtained by integrating this expression over the length of the ring.

P = ∫(i^2 dl / 6πε0 c^3) × a^2

This is the general expression for the radiated power of the current distribution around the ring.

What is probability ?

The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an occurrence may be calculated using the following formula.

Probability(Event) = Positive Results/Total Results = x/n

Given : the mean μ = 28

standard deviation σ = 4

small value = 20 and big value = 36

by chebychev's inequality,

μ - kσ = small value

28-k(4) = 20

k = 2

also,

μ + kσ = big value

28 + k(4) = 36

k = 2

The rate at which the spherical balloon's radius is increasing is

3/16π ft/min when the volume is increasing at the rate of 3 ft³/min.

Given, a spherical balloon is inflated so that its volume is increasing at the rate of 3 cubic feet per minute.

we have to find that how fast is the radius of the balloon increasing when the radius is 2 feet.

as, we know the volume of the balloon be,

V = 4/3πr³

now we have to find the rate of change of radius,

On differentiating both the sides with respect to time, we get

V' = 4/3π(3r²)dr/dt

V' = 4πr²dr/dt

as, the rate of change of volume of the balloon be, 3 ft³/min

V' = 3

3 = 4πr²dr/dt

dr/dt = 3/4πr²

Now, on putting r = 2, we get

dr/dt = 3/4π(2)²

dr/dt = 3/16π

Answer:

x = -10

y = 1

Step-by-step explanation:

To use the Gauss-Jordan Elimination Method to solve for x and y, we need to put the augmented matrix in row-echelon form. The first step is to eliminate the x-coefficient in the second row by adding 4 times the first row to the second row. This gives us the following matrix:

[ 6 6 | -18 ]

[ 0 -10 | -10 ]

Next, we need to eliminate the y-coefficient in the second row. We can do this by adding 5 times the second row to the first row, which gives us the following matrix:

[ 1 -10 | -10 ]

[ 0 -10 | -10 ]

Now, the matrix is already in row-echelon form, so we can read the solution directly from the matrix. The solution is x = -10 and y = 1. Therefore, the solutions to the system of linear equations are:

x = -10

y = 1

Note that there may be other solutions to the system of equations, depending on the specific equations that the matrix represents. The Gauss-Jordan Elimination Method will always give us one possible solution, but there may be other solutions as well.

Firstly, list out all the possible values of the random variable.Secondly, order the values from smallest to largest. Thirdly, calculate the cumulative probability for each value. Fourthly, find the value for which the cumulative probability equals or exceeds 0.5 Finally, this value is the median of the discrete random variable.The median of a discrete random variable can be found by arranging the possible values of the random variable from smallest to largest, and then calculating the cumulative probability for each value. Once the cumulative probability reaches or exceeds 0.5, the corresponding value of the random variable is the median.

Let the random variable X have values {1, 2, 3, 4, 5}.

Ordered from smallest to largest, X has the values {1, 2, 3, 4, 5}.

The cumulative probability for each value of X is calculated as follows:

P(X ≤ 1) = 0

P(X ≤ 2) = 0.2

P(X ≤ 3) = 0.6

P(X ≤ 4) = 0.9

P(X ≤ 5) = 1

If a linear regression equation predicts more than 25% of the variance in the Y scores, then the correlation between X and Y must be greater than (c) r = 0.35.

Correlation (r) quantifies the strength and direction of the linear relationship between two variables. A correlation of 0.35 indicates a moderate positive linear association, suggesting that as X increases, Y tends to increase as well, and vice versa.

When the correlation surpasses this threshold, it implies that a substantial portion of the variability in Y can be explained by changes in X. However, it's important to interpret the correlation value within the context of the specific data and the field of study.

Other factors like sample size and potential outliers can also influence the significance of the correlation. In summary, a correlation greater than (c) 0.35 signifies a meaningful connection between X and Y, contributing to the prediction of Y scores using the linear regression equation.

The distance ship travelled 7.4 units between the two observations of the lighthouse.

Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.

The formula for sine rule is sinA/a=sinB/b=sinC/c

Given that, a ship is sailing due north. At a certain point the bearing of a lighthouse is N39.8˚E and the distance is 11.5.

P is the ship, R is the light house and Q is the bearing.

PR is the distance between the ship and the light house, PR = 11.5

∠P = 43.5°, ∠Q =39.8°

Thus, ∠R = 180° -∠P-∠Q

= 180°-43.5°-39.8°

= 96.7°

By using sin rule we get

PR/sinR =PQ/sinQ

11.5/sin96.7° =PQ/sin39.8°

11.5/0.9931 =PQ/0.6401

PQ/0.6401=11.55

PQ=7.4 units

Therefore, the distance ship travelled 7.4 units between the two observations of the lighthouse.

Explanation: So, on the first day the tourists walked x/8 km.

Then the remaining distance after the first day is (x- x/8) = 7x/8 km.

On the second day, the tourists walked 4/7 of the REMAINING path, so now we multiply 4/7 by 7x/8 to get x/2 km.

So, the remaining path to travel after 2nd day is (7x/8-x/2) = 3x/8

Remember, on the third day they walked 1/3 of the remaining trail and the last 8 km.

So now, we do (3x/8 - 3x/8 x 1/3) = 8

Now, x/4 =8 ; to find x, we do 8 x 4 to get 32
