Which fraction is greater than the fraction represented by the model?
1/4
7/16
1/8
3/16
Answer:
7/16
Step-by-step explanation:
If it's easier to visualize, we can convert every into 1/16 including the graph to compare.
To convert the graph (currently in 1/8), we divide each segment to produce 16 segments, 6 of which are shaded (6/16 = 3/8).
The other fractions converted to 1/16 are as follows:
1/4 --> 4/16
7/16 --> 7/16
1/8 --> 1/16
3/16 --> 3/16
Now it's easy to tell which fraction is greater than the area represented in the model!

Find the uncertainty in a calculated average speed from the measurements of distance and time. Average speed depends on distance and time according to this function v(t,x) = x/t. Your measured distance and time have the following values and uncertainties x = 6.1 meters, 2.3 meters and t = 6.3 seconds and 1.5 seconds. What is the uncertainty in the average speed, ? Units are not needed in your answer.
Answer:
The uncertainty in the average speed is 0.134 meters per second.
Step-by-step explanation:
Let be [tex]v(t, x) =\frac{x}{t}[/tex] the average speed function, we calculate the uncertainty in the average speed by total differentials, which is in this case:
[tex]\Delta v = \frac{\partial v}{\partial x}\cdot \Delta x+\frac{\partial v}{\partial t}\cdot \Delta t[/tex]
Where:
[tex]\Delta v[/tex] - Uncertainty in the average speed, measured in meters per second.
[tex]\frac{\partial v}{\partial x}[/tex] - Partial derivative of the average speed function with respect to distance, measured in [tex]s^{-1}[/tex].
[tex]\frac{\partial v}{\partial t}[/tex] - Partial derivative of the average speed function with respect to time, measured in meters per square second.
[tex]\Delta x[/tex] - Uncertainty in distance, measured in meters.
[tex]\Delta t[/tex] - Uncertainty in time, measured in seconds.
Partial derivatives are, respectively:
[tex]\frac{\partial v}{\partial x} = \frac{1}{t}[/tex], [tex]\frac{\partial v}{\partial t} = - \frac{x}{t^{2}}[/tex]
Then, the total differential expression is expanded as:
[tex]\Delta v = \frac{\Delta x}{t}-\frac{x\cdot \Delta t}{t^{2}}[/tex]
If we get that [tex]\Delta x = 2.3\,m[/tex], [tex]t = 6.3\,s[/tex], [tex]x = 6.1\,m[/tex] and [tex]\Delta t = 1.5\,s[/tex], the uncertainty in the average speed is:
[tex]\Delta v = \frac{2.3\,m}{6.3\,m}-\frac{(6.1\,m)\cdot (1.5\,s)}{(6.3\,s)^{2}}[/tex]
[tex]\Delta v = 0.134\,\frac{m}{s}[/tex]
The uncertainty in the average speed is 0.134 meters per second.

Darryl also needs to find a better deal on bread. Rank the stores from 1 to 4 based on their unit prices. Use the drop-down menus to label the lowest price per loaf with “1” and the highest price per loaf with “4.”
Answer:
Store A:
✔ 4
Store B:
✔ 1
Store C:
✔ 3
Store D:
✔ 2
Step-by-step explanation:
The ranking of the stores from the lowest to the highest price per loaf would be: B, D, C, A.
Given is a table of bread price we need rank the unit prices of the stores from lowest price per loaf to the highest price per loaf,
To rank the stores based on their unit prices for bread, we need to calculate the price per loaf for each store.
Let's calculate the unit prices for each store and then rank them accordingly:
Store A:
Price: $6.50 for 5 loaves
Unit price: $6.50 / 5 = $1.30 per loaf
Store B:
Price: $7.50 for 10 loaves
Unit price: $7.50 / 10 = $0.75 per loaf
Store C:
Price: $18.75 for 15 loaves
Unit price: $18.75 / 15 = $1.25 per loaf
Store D:
Price: $22.00 for 20 loaves
Unit price: $22.00 / 20 = $1.10 per loaf
Based on the calculated unit prices, we can now rank the stores:
Store B: The unit price is the lowest at $0.75 per loaf.
Store D: The unit price is $1.10 per loaf.
Store C: The unit price is $1.25 per loaf.
Store A: The unit price is the highest at $1.30 per loaf.
Therefore, the ranking of the stores from the lowest to the highest price per loaf would be: B, D, C, A.

The market research department at a manufacturing plant determines that 40% of the people who purchase the plant's product during any month will not purchase it the next month. On the other hand, 20% of the people who do not purchase the product during any month will purchase it the next month. In a population of 1000 people, 200 people purchased the product this month. How many will purchase the product next month and in 2 months
Answer:
250 people will purchase the product next month
312 people will purchase the product in 2 month
Step-by-step explanation:
Total Population = 1000
People who purchased plant's product= 200
People who did not purchase = 800
Next month:
= 200 * (60%) + 800 * (20%)
= 200 * 60/100 + 800 * 20/100
= 120 + 160
= 280 people
Thus, 250 people will purchase the product next month
In 2 month:
= 280 * (60%) + 720 * (20%)
= 280 * 60/100 + 720 * 20/100
= 168 + 144
= 312 people
Thus, 312 people will purchase the product in 2 month

*BRAINLIEST* The graphs below have the same shape. Complete the equation of the blue graph.
Answer:
(x-2)^2
Step-by-step explanation:
The blue graph is shifted two units to the right of the "original" function x^2 (red). Let's recall the vertex form of a quadratic:
a (x-h)^2 + k
where a represents a constant that describes the opening of the parabola (up/down); h represents horizontal shift; and k represents vertical shift.
The blue graph is two units to the right (+2), there is NO vertical shift and NO change in how the parabola opens.
So, let's plug the appropriate values into vertex form:
(x-(+2))^2
= (x-2)^2
A basketball player averages 22.5 points scored per game with a standard deviation of 6.2 points. In one game, the number of points the athlete scored was 1.2 standard deviations below his mean. How many points below average was this value?
Answer:
7.44 is the answer
Step-by-step explanation:
Using the normal distribution, it is found that this value was 7.5 points below the average.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are given, respectively, by:
[tex]\mu = 22.5, \sigma = 6.2[/tex].
In one game, the number of points the athlete scored was 1.2 standard deviations below his mean, hence Z = -1.2 and the score was of X, so:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.2 = \frac{X - 22.5}{6.2}[/tex]
X - 22.5 = -1.2 x 6.2
X = 15.
15 - 22.5 = 7.5.
This value was 7.5 points below the average.

Find the probability that a randomly chosen customer either purchases a plasma screen TV or a DVR.
Answer:
The probability that a randomly chosen customer either purchases a plasma screen TV or a DVR is 0.50 or as a percentage 50%.
Step-by-step explanation:
A consumer electronics company has observed that 36 percent of their customers purchased a plasma screen television, that 26 percent of their customers purchases a DVR, and 12 percent of their customers purchased both a plasma screen TV and a DVR. Find the probability that a randomly chosen customer either purchases a plasma screen TV or a DVR.
We have two elements in this set
Customers that purchase a plasma Screen ( S)
Customers that purchase a DVR (D)
From the question:
Customers that purchased a plasma screen television (P) = 36% = 0.36
Customers that purchased a DVR (D)= 26% = 0.26
Customers that purchased a plasma screen television and a DVR = ( S ∩ D) 12% = 0.12
Customers that purchased a plasma screen television = ( S ∪ D)
P ( S ∪ D) = P(S ) + P( D) - P ( S ∩ D)
P ( S ∪ D) = 0.36 +0.26 - 0.12
= 0.62 - 0.12
= 0.50
Converting to percentage = 0.50 × 100 = 50%
Therefore, the probability that a randomly chosen customer either purchases a plasma screen TV or a DVR is 0.50 or as a percentage 50%

The value of both expressions when k = 3 is and when k = 5 is 45, so the expressions are.
Answer:
First is equivalent then 29 last equivalent
Step-by-step explanation:
If both expressions have the same value, then they are equal to each other.
What is an equivalent expression?The equivalent is the expressions that are in different forms but are equal to the same value.
Consider the expressions 5 + 8k and 8k + 5.
Using k = 3
5 + 8k = 8k + 5
5 + 8(3) = 8(3) + 5
5 + 24 = 24 + 5
29 = 29
Using k = 5
5 + 8k = 8k + 5
5 + 8(5) = 8(5) + 5
5 + 40 = 40 + 5
45 = 45
If both expressions have the same value after substituting and simplifying two different values for the variable, then they are equal to each other.

Then find the value that is two standard deviations above the mean.
Answer:
Mean = 30.68
Standard deviation = 6.095
Two standard deviations above the mean = 42.87
Step-by-step explanation:
Given the following data :
21; 21; 22; 23; 24; 24; 25; 25; 28; 29; 29; 31; 32; 33; 33; 34; 35; 36; 36; 36; 36; 38; 38; 38; 40
Mean = Σ(x) / n
n = 25
Σ (X) = 767
Mean (m) = 767 / 25
Mean (m) = 30.68
Standard deviation : sqrt[Σ(x - m) / n]
Using a calculator :
Standard deviation = 6.095 ( 2 decimal places)
2 standard deviations above the mean :
Mean + 2(standard deviation)
Mean + 2(6.095)
30.68 + 12.19
30.68 + 12.19
= 42.87
