Which expression when simplified is equivalent to 43,450,000

Answer:

To determine the possible lengths of the third side of a triangle with sides measuring 5 meters and 8 meters, we can use the triangle inequality theorem, which states that the sum of any two sides of a triangle must be greater than the third side.

So in this case, let's call the length of the third side "x". According to the triangle inequality theorem:

5 + 8 > x

or

x < 13

8 + x > 5

or

x > -3

Since the length of a side cannot be negative, we can disregard the second inequality. Therefore, the possible lengths of the third side, "x", are:

- 5 < x < 13

So the third side can measure any length between 5 and 13 meters, exclusive of 5 and 13.

Dan's weight can be any value between 82 kg and 96 kg

Let's call Steve's weight "x".

According to the problem, Dan weighs 14 kg more than Steve, so Dan's weight would be x + 14.

Together, their weight would be the sum of their weights

x + (x + 14) = 2x + 14

We know that their combined weight is less than 178 kg, so the inequality will be

2x + 14 < 178

Subtracting 14 from both sides

2x < 164

Dividing by 2

x < 82

So Steve's weight is less than 82 kg.

To find the possible range of Dan's weight, we can substitute x + 14 for Dan's weight

(x + 14) < (178 - x)

Simplifying

2x < 164

x < 82

x + 14 < 96

So Dan's weight is less than 96 kg.

Therefore, the length of arc AB is 3π units (or approximately 9.42 units if rounded to the nearest hundredth).

An arc is a curved segment of a circle. It is defined by two endpoints on the circle and the curve connecting them. The length of an arc is determined by the size of the angle it subtends at the center of the circle and the radius of the circle. Arcs are used in many geometric and trigonometric calculations, such as finding the length of an arc, the area of a sector, or the measure of an angle formed by two intersecting chords. In addition, arcs are commonly used in the design of structures and objects, such as arches, bridges, and curves in roads and railways.

Here,

The formula to find the length of an arc is:

length of arc = (angle measure in degrees / 360) x 2πr

where r is the radius of the circle.

In this case, the radius is 27 units and the angle measure is 20 degrees, so we can substitute these values into the formula to get:

length of arc = (20/360) x 2π(27)

length of arc = (1/18) x 54π

The length of the square is derived to be √20 using the Pythagoras rule and the area of the square is 20 cm²

The Pythagoras rule states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. 

Let the length of the square be x, thus considering the triangle formed with the radius as the hypotenuse, x as the height and x/2 as the base, then By Pythagoras rule we can evaluate for x as follows:

x² + (x/2)² = 5²

(4x² + x²)/4 = 25

5x² = 100 {cross multiplication}

x² = 20

x = √20

Area of the square = (√20)²

Area of the square = 20 cm²

The answer is either A. IQR, because Sunny Town is symmetric or B. IQR, because Beach Town is skewed.

We know that,

A distribution refers to the pattern of how data is spread out or distributed across different values or intervals. It is a way to describe and analyze the shape, center, and spread of a set of data.

According to question:

To determine the location with the most consistent temperature, we need to measure the variability of the temperature data in both locations. The measure of variability that is appropriate for this purpose is the interquartile range (IQR), which measures the spread of the middle 50% of the data.

Therefore, the answer is either A. IQR, because Sunny Town is symmetric or B. IQR, because Beach Town is skewed, depending on the shape of the distributions. If the temperature data in Sunny Town is symmetric, then the IQR would be appropriate to measure the spread of the data. If the temperature data in Beach Town is skewed, then the IQR would also be appropriate to measure the spread of the data. However, if the temperature data in either location is not skewed, then the range would not be an appropriate measure of variability.

Answer:

To draw the two triangles and state what triangle is congruent to what triangle and how we know, we start by drawing two triangles, one with vertices M, L, and R, and the other with vertices Z, J, and B. We are given that ML is congruent to ZJ, LR is congruent to JB, and angle L is congruent to angle J.

We can use the Side-Angle-Side (SAS) congruence criterion to show that the two triangles are congruent. This criterion states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.

In this case, we have ML congruent to ZJ, LR congruent to JB, and angle L congruent to angle J. Therefore, we can conclude that triangle MLR is congruent to triangle ZJB by the SAS criterion.

To determine the minimum speed of a particle moving in 3-space with position function r(t) = t^2 i + 6t j + (t^2 - 24t) k, we need to find the magnitude of the velocity vector, which is the derivative of the position vector with respect to time.

v(t) = r'(t) = 2ti + 6j + (2t - 24)k

The speed of the particle at any given time t is the magnitude of the velocity vector, which is:

|v(t)| = √(4t^2 + 36 + (2t - 24)^2) = √(4t^2 + 4t^2 - 96t + 576) = √(8t^2 - 96t + 576)

To find the minimum speed, we need to find the minimum value of |v(t)|. We can do this by finding the vertex of the parabolic function 8t^2 - 96t + 576, which corresponds to the minimum value of the function.

The vertex of a parabola of the form ax^2 + bx + c is at x = -b/2a. In this case, a = 8, b = -96, and c = 576, so the vertex is at t = -b/2a = 96/16 = 6.

So the minimum speed of the particle is:

|min speed| = |v(6)| = √(8(6)^2 - 96(6) + 576) = √(288) = 12√2

Therefore, the minimum speed of the particle moving in 3-space with position function r(t) = t^2 i + 6t j + (t^2 - 24t) k is approximately 16.97 units/sec (rounded to two decimal places). Option 4, min speed = 17 units/sec, is the closest answer.

Answer:

Step-by-step explanation:

The relationship between magnitude (M) and intensity (I) of an earthquake is given by:

I ~ 10^(1.5M + 4.8)

We can use this relationship to compare the intensities of the two earthquakes:

I1/I2 = (10^(1.5M1 + 4.8))/(10^(1.5M2 + 4.8))

= 10^(1.5(M1 - M2))

Substituting the given magnitudes, we get:

I1/I2 = 10^(1.5(8.6 - 8.2))

= 10^(1.5(0.4))

≈ 2.24

Therefore, the intensity of the first earthquake was approximately 2.24 times greater than the intensity of the second earthquake.

The correct option is B, The null hypothesis to test if the population variances differ is population variance 1 differs from population variance 2.

Variance is calculated as the average of the squared differences of each data point from the mean. In other words, variance measures how far the data points are from their average value. A high variance indicates that the data points are spread out over a wider range, while a low variance indicates that the data points are clustered more tightly around the mean.

Variance is an important concept in statistical analysis because it helps to assess the reliability of data and to make inferences about the population from a sample. It is also used in many areas of research, such as finance, economics, and engineering, to measure the risk or uncertainty associated with a set of data. Variance is closely related to other statistical measures such as standard deviation, covariance, and correlation, and is often used in conjunction with these measures to gain a deeper understanding of the data.
