The shape of the distribution of the number of clase friends for the males is best characterized as

The formula for compound interest is:

A = P(1 + r/n)^nt

where:

A is the total amount of money after t years,

P is the initial principal or deposit amount (in this case $1000),

r is the annual interest rate as a decimal (in this case 1.3% or 0.013),

n is the number of times interest is compounded per year (in this case, let's assume it's compounded annually), and

t is the number of years.

So, the function modeling the total amount of money Brigitte has over time, t, would be:

A = $1000(1 + 0.013)^t

This function shows how the amount of money in the savings account will increase as time goes on due to compound interest.

The correct option regarding the domain of the reflected absolute value function is given as follows:

All real numbers.

The domain of a function is the set that contains all possible input values for the function.

Answer:

Step-by-step explanation:

18 points in 15 hour is greater than 45 points in 36 hours.

The unit rate compares a certain number of units of one quantity to units of another quantity. In other words, the second quantity in the comparison is always 1.

45 points in 36 hours and 18 points in 15 hours.

Points per hour

45 points in 36 hours is given by,

[tex]\frac{45}{60} =1.25[/tex] points.

18 points in 15 hours is given by,

[tex]\frac{18}{15}[/tex] = 1.2 points.

You made a profit of $382.50 from selling the 45 shares of the telecommunications company.

First we need to determine the total cost of purchasing those shares, and then subtract that from the total revenue from selling them.

The total cost of purchasing the 45 shares at a price of $63.00 per share is:

45 shares x $63.00 per share = $2,835.00

The total revenue from selling the 45 shares at a price of $71.50 per share is:

45 shares x $71.50 per share = $3,217.50

To calculate the profit, we subtract the cost from the revenue:

Profit = Revenue - Cost

Profit = $3,217.50 - $2,835.00

Profit = $382.50

Therefore, you made a profit of $382.50 from selling the 45 shares of the telecommunications company.

A unit can be used for measurement, and is commonly found in mathematics to describe length, size, etc.

First, we need to know the conversion rate between the two units (pounds lb and kilograms kg)

Now, we can convert 90 pounds.

So, 90lb ≈ 41kg

(If you were to round)

The value of expression after change its measurement as;

⇒ 3.4 × 10⁻⁴ kg . m²/ s²

A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.

Given that;

The expression is,

⇒ 3.4 × 10⁵ g . cm² / s²

Now, We know that;

⇒ 1 cm = 1/1000 m

Answer:

The total number of boats Paul counted is 24 speed boats + 5 sail boats + 1 rowboat = 30 boats.

So, the experimental probability that the next boat he sees will be a sailboat is 5 sail boats / 30 boats = 1/6.

The experimental probability of an event is defined as the ratio of the number of times the event occurs to the total number of trials or observations.

In this case, Paul observed a total of 24 + 5 + 1 = 30 boats, of which 5 were sailboats.

Therefore, the experimental probability that the next boat Paul sees will be a sailboat is:

Experimental probability = number of sailboats / total number of boats

Experimental probability = 5 / 30

Experimental probability = 1/6

So the experimental probability of seeing a sailboat next is 1/6 or approximately 0.167.

To find the final price for the jacket, we need to first calculate the amount of the discount and then add the sales tax.

The amount of the discount is $65.00 * 40% = $26.00. So the price after the discount is $65.00 - $26.00 = $39.00.

The sales tax is $39.00 * 5% = $1.95. So the final price for the jacket is $39.00 + $1.95 = $40.95.

Step-by-step explanation:

Answer:

he final price for the jacket is $40.95.

Step-by-step explanation:

First, let's calculate the discount for the jacket:

Discount = $65.00 * 40% = $26.00

The price of the jacket after the discount is:

$65.00 - $26.00 = $39.00

Next, let's calculate the sales tax:

Sales tax = $39.00 * 5% = $1.95

Finally, let's add the sales tax to the discounted price to find the final price:

Final price = $39.00 + $1.95 = $40.95

So, the final price for the jacket is $40.95.

Answer:

  y = 1/8x +1/64

Step-by-step explanation:

You want the equation of the line that is tangent to the curve y = x³ -x⁴ in exactly two places.

Since the tangent line is not crossed, the difference between the line and the given curve is a 4th-degree polynomial with two roots, each of multiplicity 2. If those are 'a' and 'b', we can write for line y = mx +p, ...

  mx +p -(x³ -x⁴) = (x -a)²(x -b)² = 0

  x⁴ -x³ +0x² +mx +p = x⁴ -2(a+b)x³ +(a²+4ab+b²)x² -2ab(a+b)x +a²b²

Equating coefficients, we have ...

The coefficient of x³ tells us ...

  a +b = 1/2

The coefficient of x² tells us ...

  0 = (a +b)² +2ab

  0 = (1/2)² +2ab

  ab = -1/8

Using these value, we can find the equation of the line to be ...

  m = -2ab(a+b) = -2(-1/8)(1/2) = 1/8

  p = (ab)² = (-1/8)² = 1/64

The equation of the line is ...

  y = 1/8x +1/64

Answer:

Step-by-step explanation:

To find the angle that Mrs. Becker is looking down at, we can use the tangent function. We know the height of her eyes (6 feet) and the distance from her eyes to the ladybug (100 feet), so we can use the formula:

tan(angle) = height/distance

First, we'll solve for the angle:

angle = tan^-1(height/distance)

angle = tan^-1(6/100)

Using a calculator, we can find that the angle is approximately 0.0349 radians, or approximately 2 degrees.

So, Mrs. Becker is looking down at an angle of approximately 2 degrees.

The area of a regular polygon is determined by multiplying its perimeter by its apex. The following is a common way to write the formula: An apothem's area is equal to 1/2(ap), where a denotes the length and p the circumference. Area of pentagon = 1/2 p an is the fundamental formula for computing the area of a regular pentagon, where p stands for the pentagon's perimeter and a for its apothem.

No, [tex]4^{3}[/tex]. 5 is not equal distance away from both [tex]4^{3}[/tex] and [tex]4^{4}[/tex]. However, when x is a perfect square, it is halfway between [tex]x^{3}[/tex] and [tex]x^{4}[/tex]. 5 is halfway between [tex]9^{3}[/tex] and [tex]9^{4}[/tex].

A perfect square is an integer that is the result of multiplying an integer by itself. In other words, it is a number that can be expressed as the product of two equal integers. For example, the number 16 is a perfect square because it can be written as 4 • 4.

Every perfect square has an ending of 1, 4, 5, 6, 9 or 00. (i.e. Even number of zeros). A number that finishes in 2, 3, or 7 is not a perfect square, and so is 8.

The variance of the given frequency distribution is 60.92, and the standard deviation is option (b) 7.80.

To calculate the variance of a frequency distribution, we need to first find the mean or average of the data. The formula for calculating the mean is as follows:

mean (μ) = Σfx / Σf

where Σfx represents the sum of the products of each value and its corresponding frequency, and Σf is the sum of all the frequencies.

Using the given data, we can calculate the mean as follows:

μ = (43 + 85 + 119 + 175 + 204 + 243 + 32*1) / (3+5+9+5+4+3+1)

μ = 13.5

Next, we need to calculate the deviation of each data point from the mean. To do this, we subtract the mean from each value and square the result. The formula for this is:

(x - μ)²

Using this formula, we get the following deviations for each data point:

(4 - 13.5)² = 81.00

(8 - 13.5)² = 30.25

(11 - 13.5)² = 6.25

(17 - 13.5)² = 12.25

(20 - 13.5)² = 42.25

(24 - 13.5)² = 110.25

(32 - 13.5)² = 333.22

Next, we need to multiply each deviation by its corresponding frequency, and then sum up the results. The formula for this is:

Σf(x - μ)²

Using the above deviations and frequencies, we can calculate the sum of squares as follows:

Σf(x - μ)² = 381.00 + 530.25 + 96.25 + 512.25 + 442.25 + 3110.25 + 1 x 333.22

Σf(x - μ)² = 1827.48

Finally, we can calculate the variance by dividing the sum of squares by the total number of observations (Σf). The formula for variance is:

σ² = Σf(x - μ)² / Σf

Using the above values, we can calculate the variance as follows:

σ² = 1827.48 / 30

σ² = 60.92

The standard deviation is the square root of the variance. Therefore:

σ = √(60.92)

σ = 7.80

Therefore, the correction option is (b).
