Answer:

B

Step-by-step explanation:

The given expression can be written in scientific notation as 1.8 x 10² To obtain this, we first divide 2,520,000 by 14,000 to get 180. Then, we express this as 1.8 x 10² by moving the decimal point two places to the left and adding an exponent of 2.

For expressing very big or very small numbers in scientific notation, the number is written as the product of a number between 1 and 10 and a power of 10

To convert a number to scientific notation, first express it in the form a x 10^b, where a is a number between 1 and 10, and b is an integer.

Then, move the decimal point in a to obtain a number between 1 and 10, and add an exponent to 10 that corresponds to the number of places you moved the decimal point.

Answer:

  z = 0.80

Step-by-step explanation:

You want the value of z such that p(-z < X < z) = 0.5762 for a normal distribution.

The area outside the region of interest will be split evenly between the two tails. That is, the lower tail will hold (1 -0.5762)/2 = 0.2119 of the area of the distribution. The required value of z will be the magnitude of the Inverse CDF function for this value.

The attached calculator shows the required value of z is about 0.80.

Multiply equation 2 by 3. Then subtract the result from equation 1.

Explanation:

The 2nd equation given to us is -2x+y = 8

Triple both sides to get -6x+3y = 24

This means the original system

[tex]\begin{cases}2x-3y = 12\\-2x+y = 8\end{cases}[/tex]

is equivalent to

[tex]\begin{cases}2x-3y = 12\\-6x+3y = 24\end{cases}[/tex]

If we were to add the equations, then the y terms would cancel out because -3y+3y = 0y = 0.

Subtracting the equations will not cancel out the y terms.

-3y minus 3y = -3y -3y = -6y

Therefore the portion saying "Then subtract the result from equation 1." in answer choice B is not correct. It should be "add the equations" or "add the result to equation 1" after tripling both sides of the 2nd equation.

Answer choices A and C say the same thing more or less. Adding the original equations straight down will cancel out the x terms. Therefore, choices A and C are valid approaches to using elimination. We can cross choices A and C off the list.

Approximately 106.79 mg of Tylenol remain in Courtney's body after 4 hours.

What is the capacity of taking medication?

When someone takes medication, it is important to understand how long the medication remains in their system. This can help ensure that the medication is effective and prevent unwanted side effects. In this case, Courtney has taken 250mg of Tylenol to relieve a headache. We are asked to find out how much of the Tylenol remains in her body after 4 hours.

To answer this question, we can use the formula A=250(.73)ⁿ, where A represents the amount of Tylenol remaining in the body after n hours. The value 250 represents the initial amount of Tylenol Courtney took, and 0.73 represents the percentage of Tylenol that is eliminated from the body per hour.

When we substitute n=4 into the formula, we get A= 250(.73)⁴. This means that after 4 hours, approximately 106.79 mg of Tylenol remain in Courtney's body. This calculation assumes that Courtney has not taken any additional Tylenol during this time period.

It is worth noting that individual factors such as age, weight, and metabolism can affect how long a medication remains in someone's system. Additionally, taking medications with other substances, such as alcohol or other medications, can also impact the body's ability to eliminate the medication. Therefore, it is always important to follow the advice of a medical professional and carefully read medication labels and instructions.

A = 250(.73)ⁿ

A = 250(.73)⁴ (substituting n=4)

A ≈ 106.79

In conclusion, we can calculate that after 4 hours, approximately 106.79 mg of Tylenol remains in Courtney's body. It is important to remember that medication elimination can vary based on individual factors, and it is always best to consult a healthcare professional if you have any concerns about medication use or potential side effects.

Answer:

Step-by-step explanation:

Let's start by setting up two variables to represent the number of pounds of type A and type B coffee used in the blend. Let:

x be the number of pounds of type A coffee used

3x be the number of pounds of type B coffee used (since there were three times as many pounds of type B used as type A)

The total cost of the blend is given as $796.00, so we can set up an equation based on the cost of each type of coffee and their respective amounts:

5.95x + 4.65(3x) = 796

Simplifying and solving for x, we get:

5.95x + 13.95x = 796

19.90x = 796

x = 40

Therefore, 40 pounds of type A coffee were used in the blend. To find the number of pounds of type B coffee, we can substitute x = 40 into our expression for the number of pounds of type B:

3x = 3(40) = 120

Therefore, 120 pounds of type B coffee were used in the blend.

Let x be the scale factor.

Then, the ratio of the areas of the two triangles is x².

We are given that the larger triangle has an area of 360 square meters and the smaller triangle has an area of 2.5 square meters. So we can set up the equation:

x²(2.5) = 360

Solving for x, we get:

x = sqrt(360/2.5)

x = sqrt(144)

x = 12

Therefore, the scale factor is 12:1. Answer: 12:1.

https://brainly.com/question/16726604

Step-by-step explanation:

The drawing attached represents the question. We create a triangle with the distances from each pair of cities, and we call the distance from B to C by 'd'.

First, we need to find the angle BAC:

55° + BAC + 7° = 90°

BAC = 28°

Then, we can use the law of cosines to find the value of d:

d^2 = 470^2 + 890^2 - 2*470*890*cos(BAC)

d^2 = 470^2 + 890^2 - 2*470*890*0.8829

d^2 = 274365.86

d = 523.8 miles

a) [tex]$\sum\limits_{n=1}^{\infty} 5\left(\frac{3}{4}\right)^{n-1}$[/tex] series has sum of 20.

What is sum?

In mathematics, the sum of a series is the result obtained by adding together all the terms in a sequence of numbers.

The series that has a sum of 20 is [tex]$\sum\limits_{n=1}^{\infty} 5\left(\frac{3}{4}\right)^{n-1}$[/tex].

To see why, we can use the formula for the sum of an infinite geometric series:

[tex]S = \frac{a}{(1-r)}[/tex]

where S is the sum of the series, a is the first term, and r is the common ratio.

In this case, the first term is:

[tex]a = 5(\frac{3}{4} )^0 = 5[/tex]

And the common ratio is:

[tex]r = \frac{3}{4}[/tex]

So, the formula becomes:

[tex]S = \frac{5}{(1-\frac{3}{4} )}[/tex]

Simplifying the denominator, we get:

[tex]S = \frac{5}{\frac{1}{4}}[/tex]

Multiplying by the reciprocal, we get:

S = 20

Therefore, the sum of the series is 20, which means that the series [tex]$\sum\limits_{n=1}^{\infty} 5\left(\frac{3}{4}\right)^{n-1}$[/tex]

The measures of the numbered angles in the rhombus include the following:

In Mathematics and Geometry, a rhombus can be defined as a type of quadrilateral that is composed of four (4) equal sides and opposite interior angles that are congruent (equal). Additionally, a rhombus typically has two (2) diagonals that bisect each other at right angles (90 degrees).

This ultimately implies that, the opposite sides of a rhombus are parallel and the sum of all the four (4) interior angles is equal to 360 degrees.

m∠3 + 90° + 31° = 180°

m∠3 + 121° = 180°

m∠3 = 180° - 121°

m∠3 = 59°

m∠3 ≅ m∠6 ≅ m∠4 = 59°

Since opposite angles are equal, we have:

m∠1 ≅ m∠5 = 31°

Since the two (2) diagonals bisect each other at right angles (90 degrees), we have:
