Answer: 2280000000

Step-by-step explanation: Yes, I know it is a long number, but 10 cubed = 10 x 10 x 10, which simplified, would be 100 x 10, which is 1000. So, now you do 2.4 x 1000 to get 2400. Now you take that and multiply that by 9.5. Then, you do 10 to the 5th power, which is 100000. Now, you connect it all together, to get 2280000000. Hopefully, I did it right, if not I am sorry :/

The probability that a randomly chosen person from the given population makes a purchase is [tex]\left(\begin{array}{ccc}p\\1\end{array}\right)[/tex] *0.25.

We can calculate the probability in the following way,

Let the total population of visitors visiting to the online shopping site be P.

The estimated odds of visitors making a purchase on the online shopping website are 0.25

P(E)=0.25 and n=P

We know that the probability mass function is also known as p.m.f. of Binomial Distribution with parameters n and P.

P(X=x) = [tex]\left(\begin{array}{ccc}n\\x\end{array}\right){p^x}[/tex]* [tex](1-p)^{(1-x)}[/tex] ; 0 < p < 1 And x=0,1,2,3,...

Probability of one randomly chosen visitor making a purchase= P(x=1)

=[tex]\left(\begin{array}{ccc}p\\1\end{array}\right)[/tex] 0.25^1 * 0.75^0

=[tex]\left(\begin{array}{ccc}p\\1\end{array}\right)[/tex]*0.25

Therefore, the Probability of a random visitor making a purchase depends on the value of the population and is equal to [tex]\left(\begin{array}{ccc}p\\1\end{array}\right)[/tex] * 0.25

The system of equations that should be used is the second one:

-15 = 5A

10 = -2A + B

Here we have the following equation:

[tex]\frac{-15x + 10}{(5x - 2)^2} = \frac{A}{5x - 2} + \frac{B}{(5x - 2)^2}[/tex]

If we multiply and divide the first therm in the right side by (5x - 2) we will get:

[tex]\frac{-15x + 10}{(5x - 2)^2} = \frac{A*(5x - 2)}{(5x - 2)^2} + \frac{B}{(5x - 2)^2}[/tex]

The numerators must be equal, then we can write:

-15x + 10 = A*(5x - 2) + B

-15x + 10 = A*5x - 2A + B

Then we can write two equations, one that has x as a factor and other that does not, these are:

-15 = 5A

10 = -2A + B

Answer: B

Step-by-step explanation: TRUST

The horizontal component of the force vector is 260 pounds, and the vertical component is 150 pounds. (Option B).

To find the horizontal and vertical components of the force vector, we can use trigonometry. The horizontal component is the force acting in the direction parallel to the ground (x-axis), and the vertical component is the force acting in the direction perpendicular to the ground (y-axis).

Given that the force is 300 pounds and makes a 30° angle with the ground, we can calculate the components as follows:

Horizontal component (F_horizontal) = Force * cos(angle)

Vertical component (F_vertical) = Force * sin(angle)

Inserting in the values:

Horizontal component (F_horizontal) = 300 pounds * cos(30°)

Vertical component (F_vertical) = 300 pounds * sin(30°)

Now, let's calculate:

Horizontal component (F_horizontal) = 300 pounds * 0.866 (rounded to 3 decimal places, cos(30°) ≈ 0.866)

F_horizontal ≈ 259.8 pounds

Vertical component (F_vertical) = 300 pounds * 0.5 (rounded to 3 decimal places, sin(30°) ≈ 0.5)

F_vertical ≈ 150 pounds

Therefore, the required components of the force vector are approximately 260 pounds and 150 pounds.

The midrange for the data items in the given frequency distribution is 30.5.

Generally, To find the midrange for the data items in the given frequency distribution, we need to calculate the midpoint of each score range. The midpoint of a range is calculated by taking the average of the lower and upper bounds of the range.

For the first score range (29-30), the lower bound is 29 and the upper bound is 30, so the midpoint is (29 + 30) / 2 = 29.5.

For the second score range (30-31), the lower bound is 30 and the upper bound is 31, so the midpoint is (30 + 31) / 2 = 30.5.

Therefore, the midrange for the data items in the given frequency distribution is 30.5.

You'd set your equation and you'd get 4-2 over 20-10. You solve and you get 2/10 and because it isn't one of the answer choices you have to simplify it. To simplify it you find the common number they both share and they both share 2 so you divide both by 2. 2 divided by 2 is 1 and 10 divide by 2 is 5. So then the rate of change or slope is 1/5.

Therefore, in order for them to enjoy a party, they must be rewarded a minimum of 26 extra times.

The equals sign (=) must appear in an equation. You can think of an equation as having a left and a right side since there will be a mathematical expression on either side of it. Consider an equation to be a set of scales. Although you can use different amounts on either side, for it to be solved, each side must be equally balanced. An unknown will always be present in an algebraic equation. This is symbolized by a symbol, such x, y, or z.

Here,

Given: Given: To reward her students for good behavior, Mrs. Morton fills a marble jar with three marbles.

if there are 24 marbles in the jar. When r denotes the quantity of additional rewards for the class, then the necessary equation is 24 + 3r 100.

If we can figure it out, we'll obtain the minimum number of marbles the jar holds—24.

In order to solve the problem, take 24 away from both sides.

=> 3r ≥100 -24

=> 3r  ≥76

=> r  ≥76/3

=> r ≥ 25.33

=> r≈ 26

Therefore, in order for them to enjoy a party, they must be rewarded a minimum of 26 extra times.

Vertical angles are two angles that are opposite each other and share a common vertex. Adjacent angles are two angles that share a common side and vertex.

To find the measure of an unknown angle using these relationships, you can use the vertical angle theorem which states that if two angles are vertical, then they have equal measure. For example, if angle A and angle B are vertical angles, then angle A = angle B.

Example:

Given: Angle A = 40°

Find the measure of angle B

Solution:

Since angle A and angle B are vertical angles, then angle A = angle B

Therefore, the measure of angle B = 40°
