Answer:
The common ratio for the given geometric sequence is -1/2.
Step-by-step explanation:
The common ratio in a geometric sequence is simply the number that multiplies one term to arrive at the next term. From the sequence given, we can let the common ratio be x and determine its value using any of the following set of equations;
1/2 * x = -1/4
-1/4 * x = 1/8
1/8 * x = -1/16
using the first equation;
1/2 * x = -1/4
we divide both sides by 1/2 to solve for x.
x = (-1/4)/(1/2)
x = -1/4 * 2
x = -1/2
Thus, the common ratio for the given geometric sequence is -1/2.
Answer:
Common ratio is -1/2
Step-by-step explanation:
Common ratio is the amount between each number in a geometric sequence.
It is called the common ratio because it is the same to each number.
Common ratio is the ratio between two successive numbers in a geometric sequence.
Common is a gotten by either division or multiplication.
Therefore in the case above
1/2 x -1/2 = -1/4 ......
-1/4 x -1/2 = 1/8 ......
1/8 x -1/2 = -1/16 ....etc
Therefore our common ratio is -1/2
There are 9 players on a baseball team. In how many different ways can the coach choose players for first base, second base, third base, and shortstop?
There are 3,024 different ways the coach can choose players for first base, second base, third base, and shortstop from a team of 9 players.
Since the positions are distinct (first base, second base, third base, and shortstop), and each position can only be filled by one player, we can use the permutation formula to calculate the number of arrangements.
The coach has 9 players to choose from for the first position.
After selecting one player for first base, there remain 8 players for the second position, 7 players for the third position, and 6 players for shortstop.
The total number of different ways the coach can choose players for the four positions is obtained by multiplying these numbers:
9 x 8 x 7 x 6 = 3,024
Hence, there are 3,024 different ways.

Step-by-step explanation:
Part 1) Solve the system by elimination
Let
x----> the cost per can of grape juice
y----> the cost per can of apple juice
we know that
[tex]6x+4y=13.10[/tex] -----> equation A
[tex]4x+6y=13.10+0.60[/tex]
[tex]4x+6y=13.70[/tex] -----> equation B
Solve the system by elimination
Multiply the equation A by -6 both sides
[tex]-36x-24y=-78.6[/tex] -------> equation C
Multiply the equation B by 4 both sides
[tex]16x+24y=54.8[/tex] -------> equation D
Adds equation C and equation D
[tex]-36x-24y=-78.6\\16x+24y=54.8\\----------\\-36x+16x=-78.6+54.5\\-20x=-23.8\\x=1.19[/tex]
Substitute the value of x in the equation A
[tex]6(1.19)+4y=13.10[/tex]
[tex]4y=5.96[/tex]
[tex]y=1.49[/tex]
therefore
The cost per can of grape juice is [tex]\$1.19[/tex]
The cost per can of apple juice is [tex]\$1.49[/tex]
Part 2) Solve the system by substitution
Let
x----> the cost per can of grape juice

Answer:
[tex]\frac{24}{5}[/tex]
Step-by-step explanation:
To evaluate division of fractions, that is
[tex]\frac{9}{-5}[/tex] ÷ [tex]\frac{-3}{8}[/tex]
Leave the first fraction, change division to multiplication and turn the second fraction upside down
[tex]\frac{9}{-5}[/tex] × [tex]\frac{8}{-3}[/tex] ( cancel the 9 and 3) giving
[tex]\frac{3}{-5}[/tex] × [tex]\frac{8}{-1}[/tex]
= [tex]\frac{3(8)}{-5(-1)}[/tex] = [tex]\frac{24}{5}[/tex]
To simplify a complex fraction, multiply both the numerator and the denominator by the same factor to eliminate fraction in the denominator, cancel common factors and follow rules of algebra to maintain equality.
Explanation:To evaluate and simplify a complex fraction, we can use a strategy that involves multiplying the numerator and denominator by the same factor. For example, if our complex fraction had a denominator of 1/2, we could multiply both the numerator and the denominator by 2 to eliminate the fraction in the denominator. This approach ensures the units or variables cancel out where appropriate, leaving us with a simpler expression. When working with fractions, common factors can be identified and cancelled to simplify the fraction further. Always remember that fractions represent division, so when simplifying, divide the digit term of the numerator by that of the denominator and subtract the exponentials accordingly. This process is governed by the rules of algebra, maintaining the equality of the expression.
Find the surface area of the cone. Round your answer to the nearest hundredth

Then you do
401.92 + 14 x 8
=513.93
Hope this helps :)
Answer:
The correct answer is option option B 606.32 yd²
Step-by-step explanation:
Points to remember
Surface area of cone = πrl + πr²
Where r is the base radius and l is the lateral edge
To find lateral edge
l = √(r²+ h²) = √8² + 14² = 16.12
To find the surface area of given cone
Here r = 8 yd and l = 16.12 yd
Surface area = πrl + π r² = π * 8 * 16.12 + π8²
= 606.32 yd²
Find the inverse of the following function.
For this case we must find the inverse of the following function:
[tex]f (x) = \sqrt [3] {x + 12}[/tex]
For this, we follow the steps below:
Replace f (x) with y:
[tex]y = \sqrt [3] {x + 12}[/tex]
We exchange the variables:
[tex]x = \sqrt [3] {y + 12}[/tex]
We solve the equation for "and":
[tex]\sqrt [3] {y + 12} = x[/tex]
We raise both sides of the equation to the cube to eliminate the root:
[tex](\sqrt [3] {y + 12}) = x ^ 3\\y + 12 = x ^ 3[/tex]
We subtract 12 on both sides of the equation:
[tex]y = x ^ 3-12[/tex]
Thus, the inverse function is:
[tex]f ^ {- 1} = x ^ 3-12[/tex]
Answer:
Option B
Option: B is the correct answer.
B. [tex]f^{-1}(x)=x^3-12[/tex]
Step-by-step explanation:The inverse function f(x) is calculated in the following steps.
Put f(x)=yInterchange x and y in the equation.Now, solve for y.The function f(x) is given by:
[tex]f(x)=\sqrt[3]{x+12}[/tex]
Now, we keep:
[tex]f(x)=y\\\\i.e.\\\\y=\sqrt[3]{x+12}[/tex]
Now, we interchange x and y
[tex]x=\sqrt[3]{y+12}[/tex]
Now, on taking cube on both side of the equation we have:
[tex]y+12=x^3\\\\i.e.\\\\y=x^3-12[/tex]
i.e.
[tex]f^{-1}(x)=x^3-12[/tex]

A drawer contains 4 black socks, 3 white socks, and 2 red socks. One sock is drawn from the drawer and kept. The second sock is drawn from the drawer. What is the probability that they are both white?
The probability that they are both white if the first sock is kept and second is drawn will be 8.33%.
What is probability?Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.
A drawer contains 4 black socks, 3 white socks, and 2 red socks.
One sock is drawn from the drawer and kept.
The second sock is drawn from the drawer.
The total number of the event will be
Total event = 9
Then the probability that they are both white will be
P = (3/9) (2/8)
P = (1/3)(1/4)
P = 1/12
P = 0.0833
P = 8.33%

The probability of drawing two white socks from the drawer is 2/27.
Explanation:To find the probability that both socks drawn are white, we need to find the probability of drawing a white sock on the first draw and then drawing another white sock on the second draw.
There are a total of 9 socks in the drawer (4 black, 3 white, and 2 red).
The probability of drawing a white sock on the first draw is 3/9 (3 white socks out of 9 total socks).
After replacing the first sock, the total number of socks remains the same, but the number of white socks decreases to 2. So the probability of drawing a white sock on the second draw is 2/9.
Now, to find the probability of both events happening, we multiply the probabilities together: P(First white sock) * P(Second white sock) = (3/9) * (2/9) = 6/81 = 2/27.
Therefore, the probability that both socks drawn are white is 2/27.
Josh is having issues with his over-the-range microwave, and must decide to either have it repaired or replaced. After doing some research, he's determined that if he has to spend $200 or more on repairs, the better decision would be to replace the microwave. The appliance repair company will repair his microwave for a service call fee of $89, a parts fee of $41, and a charge of $17.50 for every 15 minutes of labor. If x represents the number of 15-minute intervals of labor, which inequality represents the number of allowable 15-minute intervals before replacing the microwave becomes the better decision? Assume that Josh won't be charged for a 15-minute interval until the full 15 minutes of labor is used.
Answer:
the inequality would be: 89+41+17.50x Is less than 200
Step-by-step explanation:
add all of the numbers together and the x with the 17.50. Add a less than inequality sign, then 200, which represents how much it would be for repairs
Answer:
[tex]130+17.50x \leq 200[/tex]
Step-by-step explanation:
The appliance repair company will repair his microwave for a service call fee of $89, a parts fee of $41, and a charge of $17.50 for every 15 minutes of labor.
If Josh spends $200 or more on repairs, he will replace the microwave.
Let x represents the number of 15-minute intervals of labor.
So, as per the scenario, the inequality becomes:
[tex]89+41+17.50x \leq 200[/tex]
=> [tex]130+17.50x \leq 200[/tex]
Solving for x
[tex]17.50x \leq 200-130[/tex]
[tex]17.50x \leq 70[/tex]
[tex]x \leq 4[/tex]
Hence, up to 4, 15 minutes interval that is one hour. the repair cost will be up to $200.
But after this it will cost more. Hence, Josh can opt for replacing after 4, 15 minutes intervals.
Tariq designed the pool shown. The owner of the pool has one square cover to use. Find the area of the space that needs to be covered. (The four corners are squares.)
The area that needs to be covered is
___ ft2.
Step 1: Find the total area. Since it is a square all the sides are 12 ft so multiply 12 by 12
12 x 12 = 144
^^^This is the total area including the area around the pool. We just need the are of the pool
Step 2: Outside of the pool there are four little 2 ft by 2 ft squares that aren't part of pool, and therefore won't need to be covered. The area of these 2 ft by 2 ft square is 4ft (2 times 2 is 4). Since there are 4 of these squares we multiply 4 by 4 to get 16. This means that 16 ft of the 144 ft we found previously are not part of the pool and we must subtract 16 from 144 to get the total pool area
144 - 16 = 128
This means that the area of the pool is 128 ft

22
Answer:
3
Step-by-step explanation:
The mean absolute deviation of the data set is approximately 3.09.
The mean absolute deviation (MAD) is a measure of variability that indicates the average distance between observations in a data set and their mean.
To calculate the MAD, you first need to find the mean of the data set. In this case, the mean is 31.375.
Then, you calculate the absolute deviation of each data point from the mean. For example, the absolute deviation of the first data point (21) is 10.375 (|21 - 31.375|).
Once you have calculated the absolute deviation of each data point, you find the average of those absolute deviations. This is the mean absolute deviation.
In the example data set, the mean absolute deviation is approximately 3.
Find the mean of the data set: (21 + 22 + 24 + 26 + 27 + 28 + 20 + 30) / 8 = 31.375
Calculate the absolute deviation of each data point from the mean. For example, the absolute deviation of the first data point (21) is 10.375 (|21 - 31.375|).
Add up the absolute deviations of all the data points. In this case, the sum of the absolute deviations is 24.75.
Divide the sum of the absolute deviations by the number of data points to find the mean absolute deviation. In this case, the mean absolute deviation is 24.75 / 8 = 3.09375.
Therefore, the mean absolute deviation of the data set is approximately 3.09.
The complete question is:What is the mean absolute deviation of the data set?

Answer:
y=1
Step-by-step explanation:
5y(2x-1)=y(x+2)+20, x=3
5y(2(3)-1)=y(3+2)+20
5y(6-1)=y(5)+20
5y(5)=5y+20
25y=5y+20
25y-5y=20
20y=20
y=20/20
y=1
5y(2x-1)=y(x+2)+20, x=3
Step 1: Substitute x with 3
5y(2(3) - 1) = y(3 + 2) + 20
Step 2: Combine like terms in the parentheses
5y(6 - 1) = y(3 + 2) + 20
5y(5) = y(3 + 2) + 20
5y(5) = y(5) + 20
Step 2: Distribute the number outside the parentheses to the numbers inside the parentheses
25y = 5y + 20
Step 3: Combine like terms by subtracting 5y to both sides
25y-5y = (5y-5y) + 20
20y = 20
Step 4: Divide 20 to both sides to isolate y
[tex]\frac{20y}{20} = \frac{20}{20}[/tex]
y = 1
Check:
5(1) (2(3) - 1) = 1(3+2) + 20

Hiro has a stack of cards with one number from the set 1, 1, 2, 2, 3, 3, 3, 4 written on each card. What is the probability that he pulls out a 3 first and then pulls out a 2 without replacing them?
Answer:
3/28
Step-by-step explanation:
Given in the question that,
stack of cards have numbers (1, 1, 2, 2, 3, 3, 3, 4)
Total number of cards = 8
Number of card with 3 on them = 3
Number of card with 2 on them = 2
To find the probability that he pulls out a 3 first and then pulls out a 2, we will multiple the probability of having 3 with 2.
Probability of having 3 = 3/8
Probability of having 2 = 2/7 (without replacing)
3/8 x 2/7 = 3/28
Thus, the answer is 3/28
Answer:3/28

The point (-2, -1) satisfies which of the following inequalities?
A) 5x - 2y + 1 > 0
B) -5x + 2y + 1 > 0
C) -2x + 5y - 1 > 0
D) 2x + 5y - 1 > 0
Ik for s fact the awnser not a
Answer:
B) [tex]-5x + 2y + 1 > 0[/tex]
Step-by-step explanation:
Given point is (-2,-1)
to find out which inequality satisfies this point we plug in x and y value of the given point in each inequality
A) [tex]5x - 2y + 1 > 0[/tex]
x=-2 and y=-1
[tex]5(-2) - 2(-1) + 1 > 0[/tex]
[tex]-10+2+1>0[/tex]
[tex]-7>0[/tex] is False
B) -5x + 2y + 1 > 0
[tex]-5(-2) +2(-1) + 1 > 0[/tex]
[tex]10-2+1>0[/tex]
[tex]9>0[/tex] is True
C) -2x + 5y - 1 > 0
[tex]-2(-2) +5(-1) -1 > 0[/tex]
[tex]4-5-1>0[/tex]
[tex]-2>0[/tex] is False
D) 2x + 5y - 1 > 0
[tex]2(-2) +5(-1) - 1 > 0[/tex]
[tex]-4-5-1>0[/tex]
[tex]-10>0[/tex] is False
if anyone could help out with this one i would really appreciate it
f(2)=?
Answer:
f(2) = 0
Step-by-step explanation:
Function f(t) is defined in three different ways depending on the value of t.
For t = 8, function f(t) is -64/t.
For t = 10, function f(t) is 14 - t.
We are not asked about f(8) or f(10). We are asked about f(2). The third definition of function f(t) is for all values of t that are not 8 or 10. 2 is not 8 or 10, so use the third definition of function f(t) and plug in 2 for t.
f(t) = t^2 - 3t + 2 for t not equal to 8 or 10.
f(2) = 2^2 - 3(2) + 2
f(2) = 4 - 6 + 2
f(2) = 0
