Answer:
x=10
Step-by-step explanation:
2x + 14 = 34
Subtract 14 from both sides of the equation. (14 - 14) (34 -14)
Next, Simplify.
2x=20
Divide both sides of 2x=20 by the same term, which is 2.
Then after all of that you come to the conclusion of x=10

Find the surface area of the prism. Write your answer as a fraction or mixed number.
Answer:
The surface area of the prism is 8/3ft²
Step-by-step explanation:
To calculate the surface area of the prism we have to use the following formula:
a = area
w = side = 2/3 ft
h = height = 2/3 ft
l = length = 2/3 ft
a = 2 * (w * h) + 2 * (w * l) + 2 * (h * l)
we replace the values that we know
v = 2 * (2/3 ft * 2/3 ft) + 2 * (2/3 ft * 2/3 ft) + 2 * (2/3 ft * 2/3 ft)
v = 2 * 4/9ft² + 2 * 4/9ft² + 2 * 4/9ft²
v = 8/9ft² + 8/9ft² + 8/9ft²
v = 24/9ft²
v = 8/3ft²
The surface area of the prism is 8/3ft²

1 bag of takis cost 2.25 dollars and 1 soda cost 1.50 dollars. if he buy 16 total items and spend 30.75 dollars,how many bags of takis did he buy and how many sodas did he bug
The bags of takis did he bought is 9 and number of sodas is 7
Given data ,
1 bag of takis cost 2.25 dollars and 1 soda cost 1.50 dollars.
Now , total number of items = 16
And total amount spend = $ 30.75
The total number of items bought is 16, so we have the equation:
x + y = 16 (equation 1)
The total amount spent is $30.75, so we have another equation:
2.25x + 1.50y = 30.75 (equation 2)
Multiply equation 1 by 1.50 to make the coefficients of y the same
1.50(x + y) = 1.50(16)
1.50x + 1.50y = 24 (equation 3)
Subtract equation 3 from equation 2 to eliminate y:
(2.25x + 1.50y) - (1.50x + 1.50y) = 30.75 - 24
0.75x = 6.75
x = 6.75 / 0.75
x = 9
Substitute the value of x into equation 1 to find y:
9 + y = 16
y = 16 - 9
y = 7
Hence , the person bought 9 bags of Takis and 7 sodas

A statistical process control monitoring system samples the inside diameter of ball bearing every hour. Measurements were taken every hour for 25 hours. The target thickness, T, is the average.
The standard deviation is approximately 0.01307. See the explanation below.
What is standard deviation?The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean.
By calculating the departure of each data point from the mean, the standard deviation may be determined as the square root of variance.
How do we calculate the standard deviation?Step 1: First, lets calculate the variance.
The formula for variance is:
\(\sigma^2 = \frac{\sum_{i=1}^{n}(x_i - \mu)^2} {n-1}\)
To get the variance ( s2 ) we must first get the mean. Our mean is 0.99892.
We subtract each value by the mean and square the difference.
(0.978-0.99892)² = 0.0004376464
(0.982-0.99892)² = 0.0002862864
(0.983-0.99892)² = 0.0002534464
(0.984-0.99892)² = 0.0002226064
(0.987-0.99892)² = 0.0001420864
(0.988-0.99892)² = 0.0001192464
(0.989-0.99892)² = 9.84064e-05
(0.99-0.99892)² = 7.95664e-05
(0.992-0.99892)² = 4.78864e-05
(0.992-0.99892)² = 4.78864e-05
(0.993-0.99892)² = 3.50464e-05
(0.994-0.99892)² = 2.42064e-05
(0.996-0.99892)² = 8.5264e-06
(0.997-0.99892)² = 3.6864e-06
(1-0.99892)² = 1.1664e-06
(1.001-0.99892)² = 4.3264e-06
(1.006-0.99892)² = 5.01264e-05
(1.007-0.99892)² = 6.52864e-05
(1.011-0.99892)² = 0.0001459264
(1.015-0.99892)² = 0.0002585664
(1.015-0.99892)² = 0.0002585664

(1.02-0.99892)² = 0.0004443664
(1.02-0.99892)² = 0.0004443664.
Step 2: Add all these numbers above
0.0004376464+0.0002862864+0.0002534464+0.0002226064+0.0001420864+0.0001192464+9.84064e-05+7.95664e-05+4.78864e-05+4.78864e-05+3.50464e-05+2.42064e-05+8.5264e-06+3.6864e-06+1.1664e-06+4.3264e-06+5.01264e-05+6.52864e-05+0.0001459264+0.0002585664+0.0002585664+0.0002585664+0.0003640464+0.0004443664+0.0004443664
=0.00410184
Step 3: Now we divide the sum by how many numbers there are. In this case we have 25.
We'll call this number n.
So n=25
For a sample (use 0.00410184 divided by (n-1) ):
So s2 =0.00410184 divided by 24
s2 = 0.00017091
Step 4 - Solve for Standard deviation:
The standard deviation is the square root of the variance. Our variance is 0.00017091.
So we only apply a square root on the variance.

Answer:
True
Step-by-step explanation:
You want to know if it is true a data set can have the same mean, median, and mode.
Mean, median, modeThe mean of a dataset is the average of all of its elements. The median is the middle one, or the average of the middle two elements. The mode is the most common element.
There is nothing in the definitions of these that prevents their being the same value. For a normally-distributed set of data, these all have the same value. A dataset does not need to be normally distributed (or even symmetrical) for these measures of center to be identical.

to 4 percent. If Calvin made monthly payments of $220 at the end of each month, how long would it take to pay off his credit card? a. If Calvin made monthly payments of $165 at the end of each month, how long would it take to pay off his credit card? months (Round up to the nearest unit.)
Rounding up to the nearest unit, it would take Calvin approximately 27 months to pay off his credit card with a monthly payment of $165.
To determine how long it would take Calvin to pay off his credit card, we need to consider the monthly payment amount and the interest rate. Let's calculate the time it would take for two different monthly payment amounts: $220 and $165.
a. Monthly payment of $220:
Let's assume the initial balance on Calvin's credit card is $3,000, and the annual interest rate is 4 percent. To calculate the monthly interest rate, we divide the annual interest rate by 12 (number of months in a year):
Monthly interest rate = 4% / 12 = 0.3333%
Now, we can calculate the time it would take to pay off the credit card using the monthly payment of $220 and the monthly interest rate. We'll use a formula for the number of months required to pay off a loan with fixed monthly payments:
n = -(log(1 - (r * P) / A) / log(1 + r))
Where:
n = number of months
r = monthly interest rate (as a decimal)
P = initial balance
A = monthly payment
Plugging in the values:
n = -(log(1 - (0.003333 * 3000) / 220) / log(1 + 0.003333))
Using a calculator, we can find:
n ≈ 15.34
Rounding up to the nearest unit, it would take Calvin approximately 16 months to pay off his credit card with a monthly payment of $220.
b. Monthly payment of $165:
We can repeat the same calculation using a monthly payment of $165:
n = -(log(1 - (0.003333 * 3000) / 165) / log(1 + 0.003333))
Using a calculator, we find:
n ≈ 26.39
Please note that these calculations assume that Calvin does not make any additional charges on his credit card during the repayment period. Additionally, the interest rate and the balance are assumed to remain constant. In practice, these factors may vary and could affect the actual time required to pay off the credit card balance.

One drawback of using focus groups is that focus group members can influence one another. The influence of group dynamics and social pressures within the group can affect individual responses and potentially lead to biased or altered opinions.
Focus groups are a qualitative research method that involves gathering a small group of individuals to participate in a guided discussion on a specific topic. While focus groups have several advantages, such as providing insights into attitudes, perceptions, and motivations, they also have drawbacks.
One of the drawbacks is that focus group members can influence one another. This phenomenon is known as the "group effect" or "groupthink." In a group setting, participants may be influenced by the opinions, perspectives, or dominant voices of others. This can lead to a conformity bias, where individuals alter their own opinions or withhold dissenting views to align with the group consensus. The influence of group dynamics and social pressures can potentially limit the diversity of perspectives and lead to biased or altered responses.
It is essential for researchers and moderators to be aware of this drawback and take steps to mitigate its impact. This may involve carefully managing group dynamics, encouraging individual opinions, providing opportunities for anonymous input, and critically analyzing the data collected to identify and separate individual perspectives from group influences.

Two gamblers play a version of roulette with a wheel as shown in the file P05_63.xlsx. Each gambler places four bets, but their strategies are different, as explained below. For each gambler, use the rules of probability to find the distribution of their net winnings after four bets. Then find the mean and standard deviation of their net winnings. The file gets you started.
a. Player 1 always bets on red. On each bet, he either wins or loses what he bets. His first bet is for $10. From then on, he bets $10 following a win, and he doubles his bet after a loss. (This is called a martingale strategy and is used frequently at casinos.) For example, if he spins red, red, not red, and not red, his bets are for $10, $10, $10, and $20, and he has a net loss of $10. Or if he spins not red, not red, not red, and red, then his bets are for $10, $20, $40, and $80, and he has a net gain of $10.
b. Player 2 always bets on black and green. On each bet, he places $10 on black and $2 on green. If red occurs, he loses all $12. If black occurs, he wins a net $8 ($10 gain on black, $2 loss on green). If green occurs, he wins a net $50 ($10 loss on black, $60 gain on green).
The mean is 65.0646 and standard deviation is 39.082 when we can see the complete form of the table in the picture.
Given that,
As seen in the spreadsheet file P05 63.xlsx, two gamblers engage in a game of wheel-based roulette. Each gambler lays four bets, but each uses a different strategy, as will be seen later. Use the probabilities to determine the distribution of each gambler's net earnings after four bets. Then calculate their net wins' mean and standard deviation. You can get going with the file.
We have to find the mean and standard deviation.
We know that,
In the picture we can see the complete table.
Here, we calculated probability as,
For example take a first row
P(red=4, black=0, green=0) = (18/37)⁴ + 0 + 0 = 0.056
So the mean is 65.0646 and standard deviation is 39.082.
Therefore, The mean is 65.0646 and standard deviation is 39.082 when we can see the complete form of the table in the picture.

Match the graph
with its inequality
6.67 Fy
a. y<-3
b. x > 2
C. 5x + 10y > 0
d. y < x
e. 2y - x = 6
f. 6x + 3y > 9
g. 3y - 4x > 12
h. y < -2x – 4
i. 8x - 6y < 10
j. 3x – 1 2 y
-10
Answer:
j.
Step-by-step explanation:
equation of a line -> y = mx + c
if you flip the equation and the inequality sign, it becomes:
\(y\) ≤ \(3x-1\)
≤ implies everything below the line
from your picture, gradient of 3 and y-intercept of -1 look possible, therefore answer is j
