Answer:

x = 5

Step-by-step explanation:

10^5=

(10 x 10) x 10 x 10 x 10=

(100 x 10)x 10 x 10=

(1000 x 10) x 10=

(10,000 x 10) = 100,000

To solve the equation 10^x = 100,000, we need to isolate x on one side of the equation. We can do this by taking the logarithm of both sides of the equation with base 10:

log(10^x) = log(100,000)

Using the logarithmic property log(a^b) = b*log(a), we can simplify the left side of the equation:

x*log(10) = log(100,000)

Since log(10) = 1, we can simplify further:

x = log(100,000)

Using a calculator, we can evaluate the logarithm to get:

x = 5 + log(10)

x = 5 + 1

x = 6

Therefore, the solution to the equation 10^x = 100,000 is x = 6.

Answer:

Therefore, the appropriate measure of variability for this data set is the IQR, and its value is 2.

Step-by-step explanation:

The range is the simplest measure of variability and is the difference between the largest and smallest values. In this case, the largest value is 20 and the smallest value is 2, so the range is:

Range = 20 - 2 = 18

However, since there are some extreme values (2 and 20), it may be better to use a measure of variability that is less affected by outliers. The interquartile range (IQR) is a good measure of variability that is less affected by extreme values.

To find the IQR, we need to find the median of the data set. The median is the middle value when the data is arranged in order. In this case, the data set has an even number of values, so the median is the average of the two middle values:

Median = (10 + 12) / 2 = 11

Next, we need to find the first quartile (Q1) and the third quartile (Q3). Q1 is the median of the lower half of the data set, and Q3 is the median of the upper half of the data set. In this case, the lower half of the data set is {2, 10, 10} and the upper half of the data set is {12, 12, 20}.

Q1 = Median of lower half = 10

Q3 = Median of upper half = 12

So, the IQR is:

IQR = Q3 - Q1 = 12 - 10 = 2

Therefore, the appropriate measure of variability for this data set is the IQR, and its value is 2.

The exponential equation that represents the function is 3x².

The finite difference between two consecutive values of f(x) is given by:

Δf(x) = f(x+1) - f(x)

Δf(-6) = f(-5) - f(-6) = 75 - 108 = -33

Δf(-5) = f(-4) - f(-5) = 48 - 75 = -27

Δf(-4) = f(-3) - f(-4) = 27 - 48 = -21

Δf(-3) = f(-2) - f(-3) = 12 - 27 = -15

The second finite differences are:

Δ²f(-6) = Δf(-5) - Δf(-6) = 6

Δ²f(-5) = Δf(-4) - Δf(-5) = 6

Δ²f(-4) = Δf(-3) - Δf(-4) = 6

Since the second finite differences are constant, the function is a quadratic polynomial of the form;

f(x) = ax² + bx + c

f(-6) = 108 = 36a - 6b + c

Since each letter can be used more than once in any given password, we can use the multiplication rule to find the total number of possible passwords.

There are 6 positions in the password, and each position can be filled with any of the 6 letters (a, e, i, o, u, y). Therefore, the total number of possible passwords is:

6 x 6 x 6 x 6 x 6 x 6 = 46656

So there are 46,656 possible passwords that can be formed if the letters can be used more than once in any given password.

It makes sense to begin with the y-intercept when sketching the graph of y = mx + b because the y-intercept is the point at which the line intersects the y-axis, where x = 0. This point gives us a starting point for the graph and allows us to plot a single point before determining the slope of the line. Once we have the y-intercept, we can use the slope to find additional points on the line, and then connect the points to create the graph of the line.

Answer:

Step-by-step explanation:

When graphing a linear equation of the form y = mx + b, where m is the slope and b is the y-intercept, it makes sense to begin with the y-intercept instead of the slope because the y-intercept gives us a point on the y-axis where the line crosses it.

In the case of the equation y = X + 2, the y-intercept is the point (0,2) on the y-axis, which is a point we can easily plot on the graph. Once we have plotted the y-intercept, we can then use the slope, which is 1 in this case, to find another point on the line by moving one unit to the right along the x-axis and one unit up along the y-axis. We can then draw a straight line through these two points to complete the graph of the line.

Starting with the y-intercept also makes sense because it gives us a sense of the vertical position of the line before we consider its slope. This can be helpful in cases where the y-intercept is a large or small number, as it can affect the scale of the graph and make it easier to read. Additionally, starting with the y-intercept can help us to quickly identify whether the line intersects the y-axis or not, and at what point.

The probability of odds of getting two matching pairs of one type of card, and three matching pairs of another in a hand of five cards are extremely low.

To calculate the odds, we can first calculate the number of ways to get two matching pairs of one type of card, which is (13 choose 2) × (4 choose 2)² since we need to choose 2 ranks out of 13, and then 2 suits out of 4 for each of those ranks. This equals 78,624.

Next, we calculate the number of ways to get three matching pairs of another type of card, which is (11 choose 3) × (4 choose 2)³, since we need to choose 3 ranks out of the remaining 11, and then 2 suits out of 4 for each of those ranks. This equals 15,024. Finally, we multiply the two probabilities to get the overall odds: (78,624 × 15,024) / (52 choose 5) = 0.000016.

Step-by-step explanation:

The required volume and total surface area of the pentagonal pyramid are 15√3

Using the Pythagorean theorem, we can find s:

s² = (3√2)² + (s/2)²

s²2 = 18 + (s²/4)

3s²/4 = 18

s² = 24

s = 2√6

Now, we can find the area of each triangle:

Area of triangle = (1/2) * apothem * side

Area of triangle = (1/2) * 3√2 * 2√6

Area of triangle = 3√3

The total area of the base pentagon is 5 times the area of each triangle:

Area of base = 5 * 3√3

Area of base = 15√3

Now, we can find the volume of the pentagonal pyramid:

V = (1/3) * Base Area * Height

V = (1/3) * 15√3 * 3

V = 15√3

To find the surface area of the pentagonal pyramid,
Area of triangular face = (1/2) * side * slant height
The slant height is the distance from the midpoint of one of the sides of the pentagon to the apex of the pyramid.
slant height² = height² + (s/2²
slant height² = 9 + 6
slant height = √15

Now, we can find the area of each triangular face:
Area of triangular face = (1/2) * 2√6 * √15
Area of triangular face = 3√10

There are five triangular faces, so the total area of the triangular faces is:

Total area of triangular faces = 5 * 3√10
The total area of triangular faces = 15√10

Adding the area of the pentagonal base, we get the total surface area:

Total surface area = 15√3 + 15√10

Answer:

To determine Martha's monthly pension, we need to use the formula provided by the Merrick Oaks School District for calculating the annual pension benefit:

Annual Pension Benefit = (Years of Service x Average of Last Three Annual Salaries) / 55

where 55 is the "pension factor" used by the district.

Using this formula, we can calculate Martha's annual pension benefit as follows:

Annual Pension Benefit = (18 x $100,000) / 55

Annual Pension Benefit = $32,727.27

Therefore, Martha's annual pension benefit is $32,727.27.

To calculate her monthly pension, we simply divide the annual pension benefit by 12:

Monthly Pension Benefit = $32,727.27 / 12

Monthly Pension Benefit ≈ $2,727.27

Therefore, Martha's monthly pension benefit would be approximately $2,727.27 if she retires after 18 years of service.

Step-by-step explanation:

the volume (V) of a triangular prism is calculated as

V = Ah ( A is the area of the triangular face and h the depth of the prism )

1

the area of the triangular face is

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = 7 and h = 5 , then

A = [tex]\frac{1}{2}[/tex] × 7 × 5 = 17.5 in²

the depth of the prism is 12 , so

V = 17.5 × 12 = 210 cm³

2

A = [tex]\frac{1}{2}[/tex] × 13 × 15 = 97.5 ft²

the depth of the prism is 2 , so

V = 97.5 × 2 = 195 ft³

3

A = [tex]\frac{1}{2}[/tex] × 11 × 4 = 22 yd²

the depth of the prism is 6 , so

V = 22 × 6 = 132 yd³

Equation to find b is 0.05b = 5.10.

Let's use the variable b to represent the cost of the haircut.

To solve for b, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.05:

b = 5.10 ÷ 0.05

b = 102

So the cost of the haircut was $102. We can check this by calculating 5% of $102, which gives us a tip of $5.10, as stated in the problem.

The probability that the publishing company produces more than 7500 books/magazines in a day is about 0.0062

To solve this problem, we need to use the standard normal distribution formula, which involves converting the given normal distribution into a standard normal distribution with a mean of 0 and a standard deviation of 1.

To convert a normal distribution with mean μ and standard deviation σ into a standard normal distribution, we use the following formula

z = (x - μ) / σ

where x is the value we want to convert, μ is the mean of the distribution, σ is the standard deviation of the distribution, and z is the corresponding value on the standard normal distribution.

Using this formula, we can convert the value of 7500 books/magazines per day to a z-score as follows

z = (7500 - 5500) / 800 = 2.5

We can then use a standard normal distribution table or a calculator to find the probability that the standard normal distribution produces a value greater than 2.5. This probability is approximately 0.006

The given values of x and y are:

x = a + bi and y = c + di

By the commutative property which states that it is a binary operation in which ab=ba whenever you change the order of the operands.

Therefore,

x = a + bi and y = c + di

Now, x × y = (a + bi) × (c + di)

 = ac + adi + bci + bdi²

= ac - bd + i(ad + bc)

Now, y × x = (c+ di) × (a + bi)
