Step-by-step explanation:

A random supporter roots the home team with probability 0.9, and the away team with probability 0.1.

Choosing 6 out of 8 supporters who root for the home team has probability

[tex]\displaystyle\binom{8}{6}\cdot 0.9^6\cdot 0.1^2 = 28\cdot0.531441\cdot 0.01=0.14[/tex]

Consider the attached figure. The height CD cuts the triangle exactly in half. This means that

[tex]\overline{AD}=\overline{BD}=\dfrac{1}{2}\overline{AB}=10[/tex]

Moreover, since CD is the height of the triangle, we know that ACD is a right triangle. We know the hypothenuse AC to be 20 feet because it is a side of the triangle, and we just found out that AD is 10. We can use the pythagorean theorem to deduce

[tex]\overline{CD}=\sqrt{\overline{AC}^2-\overline{AD}^2}=\sqrt{400-100}=\sqrt{300}[/tex]

So, the area is

[tex]A=\dfrac{bh}{2}=\dfrac{\overline{AB}\cdot\overline{CD}}{2} = \dfrac{20\cdot\sqrt{300}}{2}=10\sqrt{300}\approx 173[/tex]

Well to start off all sides are gonna be 20. To find area it’s lxw so 20•20=400

Dives 400 by 12 and you get 33.333333333 so you round that to the nearest whole foot and you get 33 feet

Answer:

B) 11:35 a.m.

Final answer:

The bottle will be half full at 11:50 PM, which is ten minutes before it is completely full at midnight, due to the exponential growth doubling the contents every ten minutes.

Explanation:

The question involves understanding exponential growth, specifically the doubling time of a population or, in a more tangible sense, the filling of a jar (or bottle). Given that a bottle doubles the amount inside every ten minutes and is full at midnight, we can calculate when the bottle will be half full by working backwards from the endpoint.

If the bottle is full at midnight, then it was half full at 11:50 PM, since the contents double every ten minutes. This reveals a common misunderstanding in our intuition about exponential growth, where significant change occurs in the final moments before reaching capacity.

In summary, to find out when the bottle will be half full, simply subtract a single doubling interval (ten minutes) from the time when the bottle is known to be full.

The percent that Container A is full after pumping its water into Container B until it is full is that Container A is 49.1% full after pumping water to Container B.

The problem asks us to determine what percent of Container A is full after Container B is full when water is transferred from Container A to Container B. We start by calculating the volume of both cylinders. The volume of a cylinder is given by the formula V = π r² h where V is volume, r is radius, and h is height.

Container A has a radius of 13 feet and a height of 13 feet, so:

π r² h ≈ 6985.3 cubic feet

Container B has a radius of 9 feet and a height of 14 feet, so:

π r² h≈ 3553.0 cubic feet

After filling Container B completely, the volume of water left in Container A is the original volume of Container A minus the volume of Container B. Therefore, the remaining volume in Container A is (6985.3 - 3553.0) cubic feet ≈ 3432.3 cubic feet.

To find the percentage full, we divide this remaining volume by the total volume of Container A and multiply by 100:

Percentage = (3432.3 / 6985.3) * 100 ≈ 49.1%.

After the pumping is complete, Container A is 48.4% full.

Calculate the volume of each container

The volume  of a cylinder is given by the formula:

[tex]\[V = \pi r^2 h\][/tex]

Volume of Container A

- Radius [tex]\( r_A = 13 \)[/tex]feet

- Height [tex]\( h_A = 13 \)[/tex] feet

[tex]\[V_A = \pi (13)^2 (13) = \pi (169)(13) = 2197\pi \text{ cubic feet}\][/tex]

Volume of Container B

- Radius [tex]\( r_B = 9 \)[/tex]feet

- Height [tex]\( h_B = 14 \)[/tex] feet

[tex]\[V_B = \pi (9)^2 (14) = \pi (81)(14) = 1134\pi \text{ cubic feet}\][/tex]

Calculate the remaining volume of water in Container A

Since Container A is initially full and the water is pumped into Container B until Container B is full, the remaining volume of water in Container A is:

[tex]\[V_{\text{remaining}} = V_A - V_B = 2197\pi - 1134\pi = (2197 - 1134)\pi = 1063\pi \text{ cubic feet}\][/tex]

Calculate the percent of Container A that is still full

The percent of Container A that is full is given by:

[tex]\[\text{Percent full} = \left( \frac{V_{\text{remaining}}}{V_A} \right) \times 100\%\][/tex]

Substituting the volumes we calculated:

[tex]\[\text{Percent full} = \left( \frac{1063\pi}{2197\pi} \right) \times 100\% = \left( \frac{1063}{2197} \right) \times 100\%\][/tex]

Simplifying the fraction:

[tex]\[\text{Percent full} = 0.484 \times 100\% = 48.4\%\][/tex]

Answer:

The correct answer options are (B) {(-6, 6), (-6, 7), (10, 12)} and (D) {(-6, 4), (10, 5)}.

Step-by-step explanation:

Here, we are given the domain {-6, 10} and we are to determine which of given relations in the options has this domain.

Domain is the set made up of the first elements of each ordered pair (x, y).

For {-6, 10} to be the domain, we will check which of the options have ordered pairs that start with -6 and 10.

If we look at option (B) {(-6, 6), (-6, 7), (10, 12)} and D. {(-6, 4), (10, 5)}, the first (two) ordered pair(s) start with -6 while the last ordered pair starts with 10.

Therefore, B and D are the correct answer option.

If I'm not wrong, there's no change in the measurement...  I think it's D.  since there's no visible change in the angle measurement. If it asked the coordinates then maybe I could elaborate. This question is confusing though. :/

The measure of angle Z after the transformation is D) 103°.Therefore , D.) 103​ is correct .

A translation does not change the measure of angles, so the measure of angle Z after the transformation is the same as the measure of angle Z before the transformation, which is 103°.

Image verification:

The image you sent shows a kite with the following angle measures:

Angle W = 96°

Angle X = 58°

Angle Y = 103°

Angle Z = 103°

The kite is translated up 3 units and 4 units to the right, which does not change the measure of any of the angles.

Therefore, the measure of angle Z after the transformation is still 103°.

Answer:

First account (simple interest)

Step-by-step explanation:

The amount of interest earned by the first account is ...

I = Prt = $2000·0.04·7 = $2000·0.28 = $560

The amount in the second account at the end of 7 year is ...

FV = P·(1+r)^t = $2000·1.02^7 = $2297.37

so you have earned $297.37 in interest on the second account.

$560 is more than $297, so the First Account (simple interest) earns more money.

Answer:

Both plans last for 1.25 hours (1 hour 15 minutes)

Step-by-step explanation:

Let x hours be the time needed for plan A and y hours be the time needed for plan B.

On Wednesday there were 5 clients who did Plan A and 3 who did Plan B. Thus, 5x+3y=10.

On Thursday there were 2 clients who did Plan A and 6 who did Plan B. Thus, 2x+6y=10.

Solve the sytem of two equation. Multiply the first equation by 2, the second by 5 and subtract them:

[tex]10x+6y-10x-30y=20-50,\\ \\-24y=-30,\\ \\y=\dfrac{30}{24}=\dfrac{5}{4}=1.25\ hours.[/tex]

Therefore,

[tex]5x+3\cdot 1.25=10,\\ \\5x=10-3.75=6.25,\\ \\x=1.25\ hours.[/tex]

[tex]\bf a^{2b}\implies a^{2\cdot b}\implies (a^2)^b\implies (a^b)^2\qquad \boxed{a^b=x}\qquad (x)^2\implies x^2[/tex]

I see no actual question, but I'm assuming that you want to find the dimensions of the rectangle.

In general, the area of a rectangle with width [tex]w[/tex] and length[tex]l[/tex] is

[tex] A = wl [/tex]

In this case, we know that the width is one-fourth of its length, which means [tex] w = \frac{1}{4}l[/tex]

If we plug this expression for w in the formula for the area, we get

[tex] A = wl = \dfrac{1}{4}l\cdot l = \dfrac{1}{4}l^2 [/tex]

We also know that the area is 9 squared units, so we have

[tex] 9 = \dfrac{1}{4}l^2 [/tex]

If we multiply both sides by 4, we get

[tex] l^2 = 36 [/tex]

Consider the square root of both sides (we only accept the positive solution, since a negative length would make no sense:

[tex] l = \sqrt{36} = 6 [/tex]

So, the length is 6, and the width is one-fourth of 6, i.e.

[tex]\dfrac{1}{4} \cdot 6 = \dfrac{6}{4} = \dfrac{3}{2} = 1.5[/tex]

Answer:

A and D

Step-by-step explanation:

ΔACD is 3 times the size of ΔABE, so the dilation uses a scale factor of 3. That only leaves choices A, D, and E.

Dilation about point A leaves point A in the same place, so choice E can be eliminated on that basis. (There is only one point A, and not a translated version, consistent with choice A.)

Point C in the larger triangle corresponds to point B in the smaller triangle, and is 4 units down from it. Hence the description of D makes sense.

Answer:

3) 2/3

4) an = 162·(1/3)^(n-1)

Step-by-step explanation:

3) A geometric sequence has a common ratio between adjacent terms. Here, that ratio is ...

r = 54/162 = 18/54 = 6/18 = 1/3

Then the next two terms can be found by multiplying by the common ratio:

6 · 1/3 = 2

2 · 1/3 = 2/3 . . . . . the sixth term

____

4) The generic expression for the n-th term of a geometric sequence with first term a1 and common ratio r is ...

an = a1·r^(n-1)

We can put in the numbers for a1 and r, and we have ...

an = 162·(1/3)^(n-1)

You can solve for 'x' in the equation 'ax = 7' by dividing both sides of the equation by 'a'. The result is 'x = 7/a'. This is based on the principle of maintaining equation equality through similar operations on both sides.

To solve for

x

in the equation

ax = 7

, you need to isolate the variable, x. This is done by

dividing

both sides of the equation by 'a'. This leaves x = 7/a. Therefore, you can find 'x' by dividing both sides of the equation by 'a'.

This process is based on the principle of equality.

You can maintain the equality of the equation by doing the same mathematical operation to both sides. Consequently, by dividing both sides by 'a', you successfully solve for x without disrupting the balance of the equation.
