What is the volume of a rectangular prism that is 120 centimeters by 2 meters by 1.5 meters in cubic centimeters? 3,600,000 cm 3 3,600 cm 3 36,000 cm 3 3.6 cm 3

Answer:

False

Step-by-step explanation:

3√2 sec(theta) + 7 = 1

3√2 sec(theta) = -6

sec(theta) = -2/√2

sec(theta) = -√2

theta = arcsec(-√2)

However, the range of secant function is [-∞, -1] U [1, ∞]. Since -√2 is not within this range, we cannot take the arcsecant of -√2. Therefore, there is no real value of theta that satisfies the equation, including 3π/4.

Therefore, the statement "The value 3π/4 is a solution for the equation 3√2 sec(theta) + 7 = 1" is False.

Amount of air (ft³)   40   36   32   28   24    20   16   12    8      4     0

The rate of change refers to the speed at which a quantity is changing with respect to time or some other variable.

It is a measure of how quickly or slowly a quantity is increasing or decreasing, and it is often represented as the slope of a graph or function. To fill the table we need to know the rate of change per minute in the air. Using the rate of change we can fill the table as follows  

Here we have

A scuba tank started with 40 cubic feet of air and was empty after a 10-minute dive.

To complete the table, calculate the rate of change of the amount of air in the scuba tank.

We know that the scuba tank started with 40 cubic feet of air and was empty after a 10-minute dive, so we can use this information to find the rate of change:

Rate of change = (final amount - initial amount) / time

Rate of change = (0 - 40) / 10 = -4 ft³/min

The negative sign indicates that the amount of air in the scuba tank is decreasing over time, which makes sense since the diver is using up the air during the dive.

Using this rate of change, we can complete the table as follows:

For 1 min  = 40 ft³ - 4 ft³ = 36 ft³

For 2 min = 36 ft³ - 4 ft³ = 32 ft³

For 3 min = 32 ft³ - 4 ft³ = 28  ft³

Similarly, we can fill the table as given below

Therefore

according to the question 77% population use a cell phone that is less than 1 year old.

Probability theory, a subfield of mathematics, quantifies the likelihood that an event is going to happen or that a statement is true. The probability for an event is a number between 0 and 1, where 0 roughly denotes how probable the event is to occur and 1 denotes certainty. A probability is a numerical representation of the likelihood that a certain event will occur. In addition to numbers from 0 to 1, probability values can also be stated as percentages between 0% and 100%. the fraction of an entire set of equally likely possibilities that result in a certain occurrence out of all possible outcomes, expressed as a ratio.

given,

The probability distribution for the age of a randomly selected young adult's cell phone can be represented using a probability mass function (PMF) as follows:

P(X = 3) = 0.01 (1% use a cell phone that is 3 years or older)

P(2 ≤ X ≤ 3) = 0.02 (2% use a cell phone that is 2-3 years old)

P(1 ≤ X ≤ 2) = 0.20 (20% use a cell phone that is 1-2 years old)

P(X < 1) = 0.77 (77% use a cell phone that is less than 1 year old)

Note that the values of the PMF correspond to the probabilities of the different age categories for the cell phones of young adults. The PMF satisfies the two main properties of a probability distribution: 1) the probabilities are non-negative, and 2) the sum of the probabilities is equal to 1.

Proof that cos²(x) + sin²(x) = 1 using the unit circle shows that this equation represents a circle with radius 1

The equation of the unit circle is given by:

x² + y² = 1

where x and y are the coordinates of any point on the circle. Let us assume that the point P on the circle makes an angle of x with the positive x-axis. Then, the coordinates of P are given by:

x = cos(x)

y = sin(x)

Substituting these values in the equation of the circlet:

cos²(x) + sin²(x) = 1

Therefore, we have shown that sin²(x) + cos²(x) = 1 using the unit circle.

Graphically, this equation represents a circle with radius 1 centered at the origin, and any point (cos(x), sin(x)) on the circle will satisfy this equation.

The ordered pair (1, 2) is a solution for the equation 4x + 2y = 8.

To find an ordered pair that is a solution for the equation 4x + 2y = 8, we need to find a pair of values for x and y that satisfies the equation when we substitute them into the equation.

One way to do this is to choose a value for x and then solve for y, or vice versa.

For example, we can choose x = 1 and then solve for y:

4x + 2y = 8

4(1) + 2y = 8

4 + 2y = 8

2y = 4

y = 2

To the right of 1.61, 9.24, and 15.09, the area under the X² curve with five degrees of freedom is 0.078, 0.0001, and 0, respectively.

A surface's area can be measured in two dimensions by multiplying its length by its breadth. It is employed to determine the size of a room or a plot of land. The size of a shape, like a circle or a square, can also be determined using area. Area is frequently expressed in square metres or square feet.

Here in the question,

(a)1.61

The following formula can be used to determine the area under the 1.61-degree curve with five degrees of freedom to the right:

Area = 1 - Φ(x; df)

Where df stands for the degrees of freedom and (x; df) is the cumulative distribution function of the chi-square distribution.

For df = 5, Φ(1.61; 5) = 0.922.

As a result, 1 - 0.922 = 0.078 represents the area under the 1.61-degree curve with 5 degrees of freedom to the right.

(b) 9.24

For df = 5, Φ(9.24; 5) = 0.9999.

As a result, 1 - 0.9999 = 0.0001 is the value of the area under the X² curve with 5 degrees of freedom to the right of 9.24.

(c) 15.09

For df = 5, Φ(15.09; 5) = 1.

As a result, 1 - 1 = 0 represents the area under the 15.09-based X² curve with 5 degrees of freedom to the right.

The area under the X² curve with five degrees of freedom to the right of 1.61, 9.24, and 15.09, respectively, is 0.078, 0.0001, and 0.

1. The solution set can be written as:

{x = [t, s, (3/2)t + (3/2)s] : t, s ∈ R}

2. The solution set can be written as:

{x = [t, s, (3/2)t + (3/2)s - 3] : t, s ∈ R}

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("="). For illustration, 2x - 5 = 13. 2x - 5 and 13 are expressions in this case. These two expressions are joined together by the sign "=".

To find the solution set in parametric vector form for the equation x₁ + 3x₂ - 2x₃ = 0, we can write:

x₁ = t      (arbitrarily setting x1 = t)

x₂ = s

x₃ = (3/2)t + (3/2)s

where t and s are arbitrary parameters.

Therefore, the solution set can be written as:

{x = [t, s, (3/2)t + (3/2)s] : t, s ∈ R}

This is a set of infinitely many vectors that lie on a plane in three-dimensional space.

Part 2

For the equation x₁ + 3x₂ - 2x₃ = -6, we can rewrite it as x₁ + 3x₂ - 2x₃ = 0 - 6, which is of the same form as the equation in Part 1, but with a constant on the right-hand side.

Using the same method as in Part 1, we can find the solution set as:

x₁ = t

x₂ = s

x₃ = (3/2)t + (3/2)s - 3

where t and s are arbitrary parameters.

Therefore, the solution set can be written as:

{x = [t, s, (3/2)t + (3/2)s - 3] : t, s ∈ R}

This is also a set of infinitely many vectors that lie on a different plane in three-dimensional space.

Comparing the two solution sets, we can see that they are both sets of infinitely many vectors and have a similar form (parametric vector form). However, they lie on different planes in three-dimensional space, and the second set is shifted downward by 3 units along the third axis.

If 1 + i is a zero of the polynomial function P(x), then its conjugate, 1 - i, must also be a zero of the polynomial, since complex zeros of polynomial functions with real coefficients always come in conjugate pairs.

To find the remaining zero, we can use polynomial division or synthetic division to divide P(x) by (x - 1 - i)(x - 1 + i), which is the quadratic factor corresponding to the two known zeros:

      2x^2 - 3x + 2

P(x) = --------------

The probability of rolling a number that is NOT between 4 and 12 is approximately 0.55 or 55%.

Probability is the concept that describes the likelihood of an event occurring. In real life, we frequently have to make predictions about how things will turn out. We may be aware of the result of an occurrence or not. When this occurs, we state that there is a possibility that the event will occur.

The range between 4 and 12 inclusive contains 9 numbers (4, 5, 6, 7, 8, 9, 10, 11, and 12) out of 20.

To find the probability of rolling a number that is NOT between 4 and 12, we need to find the probability of rolling one of the 11 numbers that are outside of this range.

The probability of rolling any one of these 11 numbers is 11/20, since there are 11 favorable outcomes out of 20 possible outcomes.

Therefore, the probability of rolling a number that is NOT between 4 and 12 is:

P = 11/20 ≈ 0.55

Step-by-step explanation:

To calculate the probability of getting at least four hearts when dealing five cards from a standard deck, we can use the concept of combinations and probability.

There are a total of 52 cards in a standard deck, and 13 of them are hearts (assuming no jokers). So the probability of drawing a heart on the first card is 13/52, or 1/4.

Now, there are two possible scenarios that would result in at least four hearts:

Four hearts and one non-heart: This can happen in C(13,4) * C(39,1) ways, where C(n, k) is the number of combinations of n items taken k at a time. The first part C(13,4) represents choosing 4 hearts out of 13, and the second part C(39,1) represents choosing 1 non-heart out of the remaining 39 cards. The total number of ways to choose 5 cards from 52 is C(52,5).

Five hearts: This can happen in C(13,5) ways, where C(13,5) represents choosing all 5 hearts out of 13.

So, the total number of favorable outcomes is C(13,4) * C(39,1) + C(13,5), and the total number of possible outcomes is C(52,5). Therefore, the probability of getting at least four hearts is:

P(at least 4 hearts) = (C(13,4) * C(39,1) + C(13,5)) / C(52,5)

Plugging in the values and simplifying, we get:

P(at least 4 hearts) = (C(13,4) * C(39,1) + C(13,5)) / C(52,5)

= (715 * 39 + 1287) / 2,598,960

= 27,885 / 2,598,960

≈ 0.0107566

So, the probability of getting at least four hearts when dealing five cards from a standard deck is approximately 0.0107566 or about 1.08%.

The function f of the line is f(x) = 2x - 2 and f(-1) = -4.

The slope of a line determines the steepness of the line and is calculated by dividing the vertical change (rise) between any two points on the line by the horizontal change (run) between those same two points. The formula for slope is (y₂ - y₁) / (x₂ - x₁), where (x₁, y₁) and (x₂, y₂) represent any two points on the line. The slope can be positive, negative, zero or undefined, depending on the direction and steepness of the line. If the line moves up from left to right, it has a positive slope, while a line that moves down from left to right has a negative slope.

From the graph we can take two points on the line (1,0) and (0,-2). Now we can find the equation of the line passing through these points, for that we can use the point-slope form of the equation of a line:

y - y₁ = m(x - x₁)

where m is the slope of the line and (x₁, y₁) is one of the points on the line.

First, we can find the slope:

m = (y₂ - y₁) / (x₂ - x₁) = (-2 - 0) / (0 - 1) = -2/-1 = 2

Next, we can choose either point and substitute the values into the point-slope equation:

y - y₁ = m(x - x₁)

Using point (1,0):

y - 0 = 2(x - 1)

Simplifying:

y = 2x - 2

Therefore, the equation of the line passing through points (1,0) and (0,-2) is y = 2x - 2. That is f(x) = 2x - 2.

f(-1) = 2 × -1 - 2 = -2 -2 = -4.
