Mr. Gordon and Mr. O want to race their Tesla's from Englewood Stem to Soldier Field. Soldier Field is approximately 10.5 km away. It takes Mr. O 30 minutes to show up to the stadium. Mr. Gordon arrives 30 minutes after Mr. O. How much faster in (Meters/second) is Mr. O's avg. speed for the race? *
Answers
The distance is the same that was covered.
Distance is speed multiplied by time.
Mr O takes 30 minutes and Mr Gordon takes 1 hour.
So the speed of Mr O is given by:
\(\text{Speed}=\frac{10.5\operatorname{km}}{1hr}=10.5\operatorname{km}\text{ /hr}\)Convert the speed in meter per second.
\(S_O=10.5\times\frac{5}{18}=\frac{35}{12}m\text{ /s}\)The speed of mr G is:
\(S_G=\frac{10.5}{0.5}=21\operatorname{km}\text{ /hr=}\frac{35}{6}m\text{ /s}\)So the difference between the speeds is:
\(\frac{35}{6}-\frac{35}{12}=\frac{35}{12}=2.9166667\text{ m/s}\)So Mr O is 2.9167 m/s faster than Mr Gordon.

Answers
Answer: 2 inches
Step-by-step explanation:
14 inches
Step-by-step explanation:
Length of the hole = 16(½) inches
Length of the dirt = 8(¾)inches
The distance between the top of the pile to the bottom of the hole = ?
Since the dirt is beside the hole and not inside the hole, we can find it's length using addition.
Distance from the top to the bottom = length of dirt + length of the hole
Length of dirt = 8×¾ = 6 inches
Length of the hole = 16 × ½ = 8 inches
Distance from the top of the dirt to the bottom of the hole = (6 + 8) inches
Distance from the top of the dirt to the bottom of the hole = 14 inches
Note: the only way we can use subtraction here is if the hole was filled with dirt, what's the distance that's left
Distance left = length of hole - length of dirt
Distance left = 8 - 6 = 2 inches .

the niagara falls incline railway has an angle of elevation of 30° and a total length of 196 feet. how many feet does the niagara falls incline railway rise vertically? ..... feet
Answers
The Niagara Falls incline railway rises vertically by approximately 98 feet.
The angle of elevation of 30° indicates the angle between the incline railway and the horizontal ground. The total length of the incline railway is given as 196 feet.
To find the vertical rise, we can use trigonometry. The vertical rise can be determined by calculating the sine of the angle of elevation and multiplying it by the total length of the incline railway:
Vertical rise = Total length × sine(angle of elevation)
Vertical rise = 196 ft × sin(30°)
Vertical rise ≈ 196 ft × 0.5
Vertical rise ≈ 98 ft
Therefore, the Niagara Falls incline railway rises vertically by approximately 98 feet.

.2. Determine whether the feasible set for each of the following systems of constraints is convex, and if not, indicate points x^1 and x² that violate definition. a) (x1)² + (x2)² > 9
x1 + x2 ,10
x1, x2 > 0
Answers
The feasible set for this system of constraints is not convex, and the points (5, 5) and (3, 7) violate the convexity definition.
To determine whether the feasible set for each system of constraints is convex, we need to analyze the constraints individually and examine their intersection.
a) (x1)² + (x2)² > 9
This constraint represents points outside the circle with a radius of √9 = 3. The feasible set includes all points outside this circle.
b) x1 + x2 ≤ 10
This constraint represents points that lie on or below the line x1 + x2 = 10. The feasible set includes all points on or below this line.
c) x1, x2 > 0
This constraint represents points in the positive quadrant, where both x1 and x2 are greater than zero.
Now, let's analyze the intersection of these constraints:
Considering the first two constraints (a and b), we can see that the feasible set consists of all points outside the circle (constraint a) and below or on the line x1 + x2 = 10 (constraint b).
To determine whether the feasible set is convex, we need to check if any two points within the set create a line segment that lies entirely within the set.
If we consider the points (5, 5) and (3, 7), both points satisfy the individual constraints (a) and (b). However, the line segment connecting these two points, which is the line segment between (5, 5) and (3, 7), exits the feasible set since it passes through the circle (constraint a) and above the line x1 + x2 = 10 (constraint b).
Therefore, the feasible set for this system of constraints is not convex, and the points (5, 5) and (3, 7) violate the convexity definition.

For how many days would the same bag feed 80 chickens
Answers
Answer:
9.6 days
Step-by-step explanation:
100 chickens, 12 days
find the days for 10 chickens: 1.2 days (to get 10 you have to divide 100 by ten, so divide 12 by ten too)
times by 8 to get the days for 80 chickens: 9.6 days
Answer: Let's assume that the bag of corn contains "C" units of corn. We know that this amount of corn can feed 100 chickens for 12 days.
To determine how long the same bag of corn would feed 80 chickens, we can use the following proportion:
(Corn units)/(chickens * days) = (Corn units)/(chickens * days)
We can set up two ratios, one for the original situation and one for the new situation, and then cross-multiply to solve for the unknown value:
C/100 * 12 = C/80 * d
where "d" is the number of days that the same bag of corn would feed 80 chickens.
Simplifying the equation, we get:
C/10 = C/80 * d
Multiplying both sides by 80, we get:
8C = Cd
Dividing both sides by "C", we get:
8 = d
Therefore, the same bag of corn would feed 80 chickens for 8 days.

Standard Deviation is a measure that shows what quantity variation (such as unfold, dispersion, spread,) from the mean exists. the quality deviation indicates a “typical” deviation from the mean. it's a well-liked live of variability as a result of it returns to the first units of live of the info set.
Main body:
N = 25
mean - 18.8
standard deviation = 3
z value of 90% in z score = 1.645
C.I. = mean± z*s/√n
C.I. = 18.8 ± 1.645*3/√25
C.I. = 18.8 ±0.99

Answers
A. Main Answer:
The hypothesis that the variability in both populations is the same against the alternative that it is larger in the second population, we can perform a permutation test using two different test statistics:
(i) the difference of sample ranges and
(ii) the ratio of sample variances. By comparing the results of both test statistics, we can draw conclusions about the variability in the populations.
(i) Difference of Sample Ranges:
1. Calculate the sample range for each sample. The sample range is the difference between the maximum and minimum values in the sample.
Sample 1 Range = Maximum value - Minimum value for Sample 1
Sample 2 Range = Maximum value - Minimum value for Sample 2
2. Calculate the observed difference of sample ranges, which is the difference between the sample range of Sample 2 and Sample 1.
3. Pool the data from both samples and shuffle them randomly, keeping the same sample sizes.
4. Calculate the difference of sample ranges for the shuffled data.
5. Repeat steps 3 and 4 many times (e.g., 1000 permutations) to obtain a distribution of the difference of sample ranges under the null hypothesis (where variability is the same in both populations).
6. Compare the observed difference of sample ranges from step 2 with the distribution obtained from the permutations.
(ii) Ratio of Sample Variances:
1. Calculate the sample variance for each sample.
2. Calculate the observed ratio of sample variances, which is the ratio of the sample variance of Sample 2 to the sample variance of Sample 1.
3. Pool the data from both samples and shuffle them randomly, keeping the same sample sizes.
4. Calculate the ratio of sample variances for the shuffled data.
5. Repeat steps 3 and 4 many times (e.g., 1000 permutations) to obtain a distribution of the ratio of sample variances under the null hypothesis.
6. Compare the observed ratio of sample variances from step 2 with the distribution obtained from the permutations.
By comparing the results of both test statistics, we can assess whether the variability in the second population is significantly larger than the first population. If both test statistics consistently indicate larger variability in the second population, it provides evidence against the null hypothesis and suggests that the variability in the second population is indeed larger.
