I need help finding the standard deviation

Answer:

[tex]2 \, \dfrac{4}{25} \textrm{ ft}[/tex]

Step-by-step explanation:

First, solve for how many feet Jason has dug after 40 minutes:

[tex]\dfrac{\dfrac{3}{5} \textrm{ ft}}{10 \textrm{ min}} \times 40 \, \textrm{min} = 2 \dfrac{2}{5} \, \textrm{ft}[/tex]

So, the hole he has dug is 2 2/5 ft deep.

Next, we can solve for how deep the hole will be after placing a plant in by simply multiplying 9/10 by the depth of the hole dug.

[tex]2\, \dfrac{2}{5} \times \dfrac{9}{10} = \dfrac{12}{5} \times \dfrac{9}{10} = \dfrac{6 \times 9}{5 \times 5} = \dfrac{54}{25} = 2 \, \dfrac{4}{25} \textrm{ ft}[/tex]

Answer: 240

Step-by-step explanation:

The difference in cost between the two plans after 18 months is $240.

This is because the cost of Company A is consistently $35 more per month than that of Company B, which therefore would add up to $630 after 18 months.

The linear equation representing the cost of Company A is Y = 35X + 40, while the linear equation representing the cost of Company B is Y = 50X.

After 18 months, X would equal 18, and substituting this value into the two equations, we get the following for Company A:

Meanwhile, for Company B, we get:

The difference between these two values for different internet service providers is:

Step-by-step explanation:

The total cost of 0.6 pounds of blueberries and 1.8 pounds of clementine's is, $6.6.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A pound of blueberries costs $3.50 and a pound of clementine's costs $2.50.

Hence, We get;

The total cost of 0.6 pounds of blueberries and 1.8 pounds of clementine's is,

⇒ 0.6 × $3.50 + 1.8 × $2.50

⇒ $2.1 + $4.5

Answer: y = 40deg, x = 80deg

Step-by-step explanation:

1. Because we see that there are parallel lines in the triangle to the left, we know that two of the angles of that triangle are 50deg

2. using the fact that triangles have a total of 180deg we get x = 80deg

To solve for y, we also know that there are two angles in that triangle which are the same, and one of them is y, therefore 2y + 100deg = 180deg, meaning 7 = 40deg

The price of each bag of popcorn and the price of each drink is $7.5 and $4 respectively.

Let the drinks be represented as d.

Let the popcorn be represented as p.

From the information, Xochitl went into a movie theater and bought 6 bags of popcorn and 4 drinks, costing a total of $65. Thus will be:

6p + 4d = 65

Alonso went into the same movie theater and bought 9 bags of popcorn and 8 drinks, costing a total of $107.50. This will be:

9p + 8d = 107.50

Equating the equation

6p + 4d = 65 ..... i

9p + 8d = 107.50 ..... ii

Multiply equation i by 8

Multiply equation ii by 4

48p + 32d = 520

36p + 32d = 430

12p = 90

Divide

p = 90/12

= 7.5

6p + 4d = 65 .

6(7.5) + 4d = 65

4d = 65 - 45

4d = 20

d = 20/4

drink = 5

The area represented by g(x) is the definite integral of g(x) with respect to t from t=0 to t=x:

g(x) = ∫(t^4) dt from 0 to x

To find g'(x) using Part 1 of the Fundamental Theorem of Calculus, we know that:

g'(x) = d/dx (∫(t^4) dt from 0 to x) = (t^4) evaluated at x = x^4

To find g'(x) using Part 2 of the Fundamental Theorem of Calculus, we can evaluate the integral:

g(x) = ∫(t^4) dt = (1/5)t^5 evaluated from 0 to x = (1/5)x^5

then take the derivative of g(x) with respect to x:

g'(x) = d/dx ((1/5) x^5) = (1/5) * 5x^4 = x^4

The probability that a randomly selected student takes both computer science and statistics courses as electives is 0.26

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

We can use the formula for the probability of the intersection of two events:

P(A and B) = P(A) + P(B) - P(A or B)

where A and B are the events of taking computer science and statistics courses as electives, respectively.

Given:

P(A) = 0.41 (probability of taking computer science)

P(B) = 0.48 (probability of taking statistics)

P(A or B) = 0.63 (probability of taking at least one of these two courses)

So,

P(A and B) = 0.41 + 0.48 - 0.63 = 0.26

Therefore, the probability is 0.26, rounded to two decimal places.

A number or ratio that is expressed as a fraction of 100 is known as a percentage in mathematics. There are also sporadic uses of the acronyms "pct.," "pct," and "pc." However, the percent sign "%" is widely used to signify it. There are no dimensions to the percentage amount. Percentages are essentially fractions because they have a numerator of 100. Put the percent sign (%) next to a number to indicate that it is a percentage. For instance, you would score a 75% if you answered 75 out of 100 questions on a test correctly (75/100). Divide the money by the total to get percentages, then multiply the result by 100. The formula (value/total) x 100% is used to determine the percentage.

Citizens have the freedom and independence to choose their own career paths, as well as the ability to change jobs relatively easily if they desire.

To find the approximate difference in the percentage of people that liked pepperoni on their pizza and the percentage of people that only liked cheese pizza, we need to find the percentage of people that liked pepperoni and the percentage of people that only liked cheese, and then subtract the smaller percentage from the larger percentage.

From the graph, we can see that 30 people liked pepperoni, 20 people liked mushrooms, 15 people liked sausage, and 10 people liked cheese and olives.

The total number of people Jimmy asked is 30+20+15+10 = 75

The percentage of people that liked pepperoni is 30/75*100 = 40%

The percentage of people that only liked cheese is 10/75*100 = 13.33%

The difference between 40 and 13.33 is 26.67%.

So, the approximate difference in the percentage of people that liked pepperoni on their pizza and the percentage of people that only liked cheese pizza is 26.67%.

The area of a rectangle is length ✕ width. So, width = area/length, i.e., 24 square units/4 units or 6 units.

Because its sides are coupled, it only has two distinct dimensions. The rectangle’s length is traditionally the longer of these two dimensions, although when the rectangle is displayed standing on the floor, the vertical side is commonly termed the length.

A rectangle’s opposite sides are equal and parallel. Because a rectangle is a 2-D form, it has two dimensions: length and breadth. The length of the rectangle is the longer side, while the width is the shorter side. Square units of measurement include square inches, square feet, and square meters.

A fractional number can be checked to discover if it is a prime number. A statement having two spherical geometry and an equal sign in the middle is referred to as a mathematical equation. Every variable's degrees are listed in descending order in the general form of any equation. The formula for a linear equation is x + b = 0.

given

Now solve any problem for one variable. In the first equation, I'll find the value of x:

200mph = p - w

On both sides, add w:

p = 200mph Plus w

Now that we have the x from the first equation, we can use it to solve for w in the second equation:

200 mph + w + w Equals 300 mph

Add related phrases together for 300 mph: 200 mph plus two

200 mph on both sides are subtracted:

100mph = 2w

50 mph divided by two is w.

Therefore, the wind's speed is 50 mph.

To find the plane's speed, enter the value we just discovered back into either equation. I'll enter it into the first equation.

200 mph = (p - 50 mph)

50 mph extra on both sides

250mph = p

The solution ax2 + bx + c = 0 can be solved using  quadratic equation

x = (-b (b2 - 4ac))/2a to get the roots of the problem.

Just using equations x = ax2 + bx + c = 0 and a 0, a quadratic function is a 2nd polynomial problem in one variable. It is a third polynomial problem, hence the foundational theorem of algebra guarantees that there is least one solution. There may also be real or sophisticated solutions. The quadratic formula makes solving any quadratic equation easier for us. In order to solve this equation, we must first change its form to appear as ax2+bx+c=0, in which a, b, and d are the coefficients. Therefore, we add these coefficients to the method: (-b(b2-4ac))/ (2a).

Here,

The problem ax2 + bx + c = 0 can be solved using

the method x = (-b (b2 - 4ac))/2a to get the roots of the problem.
