Answer:

<h2>Dolores is incorrect</h2>

Step-by-step explanation:

the surface area of the 1 ticket zone is ( $\pi 9^{2}$ )-( $\pi 6^{2}$ ) which is ≈ 141 in ^3

the surface area of the 2 tickest zone is ( $\pi 6^{2}$ )-( $\pi 1^{2}$ ) which is ≈ 110 in^3

141>110

the surface area of the 1 ticket zone is larger than the area of the two ticket zone so its not equal, so the one ticket zone has the highest probability

2. How many square yards of carpet will be needed for a 21 ft by 15 ft room?

ipn [44]

Answer:

The answer to your question is: 35 yd²

Step-by-step explanation:

To solve this problem, just find the data, the formula, substitute the values in the formula and find the result.

Data

Square yards = ?

Length = 21 ft

Width = 15 ft

Formula

Area of a rectangle = length x width

Substitution

Area of a rectangle = 21 ft x 15 ft

Area of a rectangle = 315 ft²

Area of a rectangle = square yards of carpet

Finally, convert ft² to yd²

315 ft² = 35 yd²

Result

Square yards of carpet = 35 yt²

A geometric series has second term 375 and fifth term 81 . find the sum to infinity of series .

Eduardwww [97]

Answer: $\bold{S_{\infty}=\dfrac{3125}{2}=1562.5}$

<u>Step-by-step explanation:</u>

a₁, 375, a₃, a₄, 81

First, let's find the ratio (r). There are three multiple from 375 to 81.

$375r^3=81\\\\r^3=\dfrac{81}{375}\\\\\\r^3=\dfrac{27}{125}\qquad \leftarrow simplied\\\\\\\sqrt[3]{r^3} =\sqrt[3]{\dfrac{27}{125}}\\ \\\\r=\dfrac{3}{5}$

Next, let's find a₁

$a_1\bigg(\dfrac{3}{5}\bigg)=375\\\\\\a_1=375\bigg(\dfrac{5}{3}\bigg)\\\\\\a_1=125(5)\\\\\\a_1=625$

Lastly, Use the Infinite Geometric Sum Formula to find the sum:

$S_{\infty}=\dfrac{a_1}{1-r}\\\\\\.\quad =\dfrac{625}{1-\frac{3}{5}}\\\\\\.\quad =\dfrac{625}{\frac{2}{5}}\\\\\\.\quad = \dfrac{625(5)}{2}\\\\\\.\quad = \large\boxed{\dfrac{3125}{2}}$

Suppose 15 Argus student ride the city bus to school. Out of a total of 220 students, what percent ride the city bus (round to n

Oksana_A [137]

Answer:

Step-by-step explanation:

(15/220) x 100 = 6. 8182 = 7%

to convert to percentage multiply by 100

To convert to the nearest whole number, look at the first number after the decimal. If it is greater or equal to 5, add 1 to the number after the decimal. 8 is greater than 5, so add one to 6
