What is Standard Deviation?

A standard deviation (or σ) is a measure of how widely distributed the data is in reference to the mean. A low standard deviation suggests that data is grouped around the mean, whereas a large standard deviation shows that data is more spread out.

Solution:

Mean = 100

Standard Deviation = 13

To solve the given problem we need to calculate the Z - Score

Z = X - Mean / Standard Deviation

P(X > 115)

Z = 115 - 100 / 13

Z = 15 / 13

Z = 1.15 Percentile

No solutions exist to this system of equations

A system of equations is said to be inconsistent if the two equations do not agree, meaning that there is no set of values that can simultaneously satisfy each equation. For example, the most basic inconsistent system of equations could be x = 4 a nd x = 5 at same time which is not possible.

A single equation in three unknowns can be interpreted geometrically in 3-dimensional space. If we look at a system of such linear equations, the solution set is the set of all points lying in all of the corresponding planes.

Systems of equations in three variables that are inconsistent could result from three parallel planes, two parallel planes and one intersecting plane, or three planes that intersect the other two but not at the same location.

Hence, No solutions exist to this system of equations

Your answer is option b)

The time at which a star rises shifts approximately 4 minutes earlier each day, due to Earth's orbit around the Sun. Since there are roughly 30 days in a month, we can calculate the change in the rise time of Aldebaran over the course of a month.

Step 1: Calculate the time change over one month
30 days * 4 minutes per day = 120 minutes

Step 2: Convert minutes to hours
120 minutes ÷ 60 minutes per hour = 2 hours

Step 3: Subtract the time change from the current rise time
2:00 am - 2 hours = 12:00 am (midnight)

Therefore, you can expect Aldebaran to rise next month at midnight. The correct answer is b) midnight.

Answer:

12 nickels

21 dimes

16 quarters

Step-by-step explanation:

9 extra dimes : 9 x 10 = 90

4 extra quarters : 4 x 25 = 100

total of the extras : 100 + 90 = 190

remaining amount: 670 - 190 = 480

remaining amount are made up of equal number of nickel, dimes and quarters, thus

5 + 10 + 25 = 40 ( 1 set of each type)

480 / 40 = 12 sets

therefore there are

12 nickels

12 + 9 = 21 dimes

12 + 4 = 16 quarters

Step-by-step explanation:

\( \frac{( {32}^{x} \times {25}^{x})} { {15}^{x} } = {15}^{2} \)

When you multiply two variables or numbers or with different bases but with the same exponent, you can simply multiply the bases and use the same exponent. For example:

x^a*y^a= (xy)^a

\( { (\frac{32 \times 25}{15} })^{x} = {15}^{2} \)

\( { (\frac{32 \times 5}{3} })^{x} = {15}^{2} \)

\( { (\frac{160}{3} })^{x} = 225\)

x= log (225) ÷ log ( 160/3)

Step-by-step explanation:

By considering the cases of including and excluding the 'n-th' element, we obtain the recurrence relation is C(n) = C(n-1) + C(n-1).

The first term, C(n-1), represents the number of subsets that exclude the 'n-th' element. Since we exclude this element, we are essentially counting the subsets of a set with 'n-1' elements.

The second term, C(n-1), represents the number of subsets that include the 'n-th' element. Since we include this element, we need to count the subsets of a set with 'n-1' elements as well.

By adding these two terms, we obtain the total number of subsets for a set with 'n' elements.

To use the recurrence relation, we need to establish initial conditions or base cases. These are specific values of C(n) that we know beforehand.

For the subsets of a set with 0 elements, there is only one possible subset: the empty set {}. Therefore, we have:

C(0) = 1

With this initial condition, we can start using the recurrence relation to calculate the number of subsets for sets with larger numbers of elements.

To use the recurrence relation, we start with the initial condition C(0) = 1. Then, we can iteratively calculate C(n) for larger values of 'n' using the recurrence relation:

C(1) = C(0) + C(0) = 1 + 1 = 2

C(2) = C(1) + C(1) = 2 + 2 = 4

C(3) = C(2) + C(2) = 4 + 4 = 8

The ratings for the movie on a scale from one to four stars are measured on an ordinal scale.

The scale of measurement for the movie ratings is ordinal. In an ordinal scale, the values have a specific order or ranking, but the intervals between the values are not necessarily equal. In this case, the movie critic rates the movie on a scale from one to four stars, indicating the quality or desirability of the movie. Each star rating represents a distinct level of evaluation, with four stars indicating the highest rating and one star representing the lowest.

However, the difference between each rating is not quantitatively defined. For example, the difference between a two-star and three-star rating is not necessarily equivalent to the difference between a three-star and four-star rating. Therefore, the movie ratings on this scale are considered to be on an ordinal scale.

Therefore, the ratings for the movie on a scale from one to four stars are measured on an ordinal scale because they represent a ranking without equal intervals between the ratings.

The equation used to determine the number of days, x, required for the substance to decay to 63 grams is: x ≈ 83.60

To determine the number of days, x, required for a radioactive substance to decay to 63 grams, we can use the exponential decay formula. The equation that represents the decay of a radioactive substance over time is:

N(t) = N₀ * (1/2)^(t/h)

Where:

N(t) is the remaining mass of the substance at time t

N₀ is the initial mass of the substance

t is the time elapsed

h is the half-life of the substance

In this case, we have an initial mass of 475 grams, and we want to find the number of days required for the substance to decay to 63 grams. We can set up the equation as follows:

63 = 475 * (1/2)^(x/20)

To solve for x, we can isolate the exponential term on one side of the equation:

(1/2)^(x/20) = 63/475

Next, we can take the logarithm (base 1/2) of both sides to eliminate the exponential term:

log(base 1/2) [(1/2)^(x/20)] = log(base 1/2) (63/475)

By applying the logarithmic property log(base b) (b^x) = x, the equation simplifies to:

x/20 = log(base 1/2) (63/475)

Finally, we can solve for x by multiplying both sides of the equation by 20:

x = 20 * log(base 1/2) (63/475)

Using a calculator to evaluate log(base 1/2) (63/475) ≈ 4.1802, we find:

x ≈ 20 * 4.1802

x ≈ 83.60

According to the given statement The faster computer will take 2 minutes to send out the company's email on its own.

To solve this problem, let's assign variables to the given information. Let "x" represent the time it takes the slower computer to send out the company's email on its own, and let "y" represent the time it takes both computers working together to send out the email.

According to the problem, it takes two computers "y" minutes to send out the email, and it takes the slower computer "x" minutes to do the job on its own.

Since the two computers are working together, we can set up the following equation: 1/x + 1/y = 1/t, where "t" represents the time it takes the faster computer to do the job on its own.

Substituting the given values into the equation, we have: 1/x + 1/y = 1/2y

To find the value of "t", we need to solve for "y" in terms of "x". Multiply both sides of the equation by 2xy to eliminate the denominators:

2y + 2x = xy

Rearranging the equation, we get:

xy - 2y - 2x = 0

Now, let's factor the equation:

y(x - 2) - 2(x - 2) = 0

Simplifying further:

(x - 2)(y - 2) = 0

Since we are looking for the time it takes the faster computer to do the job on its own, we disregard the solution (y - 2) = 0, which gives us y = 2.

Therefore, the faster computer will take 2 minutes to send out the company's email on its own.

To show that the given equations represent trigonometric identity statements, we will simplify each equation and demonstrate that both sides of the equation are equal.

Starting with sec²θ(1 - cos²θ):

Using the Pythagorean identity sin²θ + cos²θ = 1, we can rewrite sec²θ as 1 + tan²θ. Substituting this into the equation, we get:

(1 + tan²θ)(1 - cos²θ)

= 1 - cos²θ + tan²θ - cos²θtan²θ

= 1 - cos²θ(1 - tan²θ)

= sin²θ

Thus, the equation simplifies to sin²θ, which is a trigonometric identity.

For cosx(secx - cosx) = sin²x:

Using the reciprocal identities secx = 1/cosx and tanx = sinx/cosx, we can rewrite the equation as:

cosx(1/cosx - cosx)

= cosx/cosx - cos²x

= 1 - cos²x

= sin²x

Hence, the equation simplifies to sin²x, which is a trigonometric identity.

Considering cosθ + sinθtanθ = secθ:

Dividing both sides of the equation by cosθ, we obtain:

1 + sinθ/cosθ = 1/cosθ

Using the identity tanθ = sinθ/cosθ, the equation becomes:

1 + tanθ = secθ

This is a well-known trigonometric identity, where the left side is equal to the reciprocal of the right side.

Simplifying (1 - cos∝)(cosec∝ + cot∝):

Expanding the expression, we have:

cosec∝ - cos∝cosec∝ + cot∝ - cos∝cot∝

= cot∝ - cos∝cot∝ + cosec∝ - cos∝cosec∝

= cot∝(1 - cos∝) + cosec∝(1 - cos∝)

= cot∝tan∝ + cosec∝sec∝

= 1 + 1

= 2

Thus, the equation simplifies to 2, which is a constant value.
