Issey's current location is the Lincoln Memorial. She uses her smartphone to look up walking directions to the Jefferson Memorial. She walks 1/2 mile every 1/8 hour. If the distance between the 2 memorials is 1 1/5 miles, it will take Issey how many minutes to walk from the Lincoln Memorial to the Jefferson Memorial.
a. 18 minutes
b. 24 minutes
c. 36 minutes
d. 72 minutes
Answers
To find out how long it will take Issey to walk from the Lincoln Memorial to the Jefferson Memorial, we need to divide the total distance by the distance she covers in one hour, and then convert the result to minutes.
First, let's convert Issey's walking speed to miles per hour:
1/2 mile every 1/8 hour = 4 miles per hour
Now we can calculate the time it will take Issey to walk the 1 1/5 miles:
Time = Distance ÷ Speed
Time = 1 1/5 miles ÷ 4 miles per hour
Time = 0.3 hours
Finally, let's convert this to minutes:
0.3 hours x 60 minutes per hour = 18 minutes
Therefore, it will take Issey 18 minutes to walk from the Lincoln Memorial to the Jefferson Memorial.
It will take Issey 288 minutes to walk from the Lincoln Memorial to the Jefferson Memorial.
Explanation:To find out how long it will take Issey to walk from the Lincoln Memorial to the Jefferson Memorial, we can divide the total distance by the walking speed. Issey walks 1/2 mile every 1/8 hour, which is equivalent to 4/8 miles per hour or 1/4 miles per hour. The distance between the two memorials is 1 1/5 miles, which is the same as 6/5 miles. To find the time it takes, we divide the distance by the speed: (6/5) / (1/4) = 24/5 = 4.8 hours. To convert this to minutes, we multiply by 60: 4.8 * 60 = 288 minutes.

Tameka surveys every fourth customer leaving two different self-service yogurt shops. She asks customers how much they spent on a single cup of yogurt. The results of her survey are shown in the box plots below. What is the difference in the median cost for a single cup of yogurt purchased at Yummy Yogurt and a single cup of yogurt purchased at Yo's Yogurt Shop? How do the interquartile ranges differ for the costs at the two yogurt shops? What can be inferred about the price per ounce at the yogurt shops based on the results of the survey?
Answers
What we can deduce from both box plots is that: Yummy's yoghurt shop has a higher average cost than Yo's Yoghurt shop.
How to Interpret the box plot?The box plot is a visual way of presenting a dataset where the rectangle is used to represent the quartiles. Box plots are useful as they show the skewness of a data set
The box plot shape will show if a statistical data set is normally distributed or skewed.
When the median is in the middle of the box, and the whiskers are about the same on both sides of the box, then the distribution is symmetric.
When the median is closer to the bottom of the box, and if the whisker is shorter on the lower end of the box, then the distribution is positively skewed (skewed right).
When the median is closer to the top of the box, and if the whisker is shorter on the upper end of the box, then the distribution is negatively skewed (skewed left).
Looking at both box plots, it is clear that:
Yummy's yoghurt and Yo's Yoghurt are skewed to the right. Thus, Yummy's yoghurt shop has a higher average cost than Yo's Yoghurt shop.

And also
List all the numbers between 1 and 50 that do not appear in this multiplication table. Why are they missing?

Answer:
Step-by-step explanation:
a. Shade all products in this multiplication table that appear most frequently - 6, 8, 12, 18, and 24. All numbers appear 4 times on the table.
b. 6=3x2=2x3=1x6=6x1

18=9x2=2x9=3x6=6x3
24=4x6=6x4=3x8=8x3
c. The numbers which appear 4 times have two distinct factorizations into single digit numbers (up to the order of the factors): for example, 24=4x6=3×8.
d. The numbers that do not appear in the multiplication table are 11, 13, 17, 19, 23, 29, 31, 37, 39, 41, 43, 47
e. The reason is that they are all prime numbers that are more than 9.
The values in the table describe a data set.
Minimum 20
Mean 30
Mean Absolute Deviation 3.5
Median 35
Interquartile Range 10
Maximum 55
Which value can be used to describe how the values in the data set vary with a single number?
A. median
B. maximum
C. interquartile range
D. mean
Answers
The IQR is 10, indicating the middle 50% of the data values lie within the range of 28 to 43 (35 +/- 10 is 28-43).
The other choices are:
Mean (30) - Describes the central tendency but not variability.
Median (35) - Also describes central tendency but IQR gives a better sense of spread.
Maximum (55) - Only describes the upper limit, not variability.
So the interquartile range (IQR) of 10 is the best choice to capture how spread out or varied the values in the data set are.
The answer is C. interquartile range

D. Mean Absolute Deviation

a) the predicted hourly pay rate for a cashier who doesn't have any experience.
In this problem, the scatterplot was reduced into a linear function modeled by the equation y=0.94x+7.86 where y is the pay in $ per hour and x is years of experience indicating pay is dependent on the independent factor of years of experience. 0 years when plugged into the equation yields this through substitution. 0.94(0)+7.86=7.86$ which is the y-intercept
b)this is simply substitution as one can plug in 7 as x 0.94(7)+7.86=14.44$ or appx. 14$
c) for this problem it asks us the predicted difference in the hourly pay rate however the equation y=0.94x+7.86 tells us for every x year pay goes up an average of 0.94$, therefore, the increase is 0.94$.
Overall, this problem challenges the student's understanding of linear equations and the meaning of x and y in relation to one another in a graph.

George wrote seven tests and each was marked out of 100. No two of his marks were the same. He recorded the seven marks to do a statistical analysis. He accidentally recorded his highest mark higher than it actually was. How many of the following are altered because of his mistake? 1. Mean 2. Median 3. Minimum test score 4. Range
Answers
Explanation: median isn't affected because it is the middle value of all the values. If the highest score is already at the end of the list, then it won't go up or down if the score is even higher. Minimum isnt affected because that is the lowest score, which has seemingly been entered correctly. Mean is affected because it is the average. If one score is higher than it should be, it will raise the average. Range isnaffected because it is the number in between the max and min (max-min). If the max is higher, then the range increases
Mean: Calculated by adding all the test scores together and then dividing by the total number of tests, so the error in the highest score does not affect the mean.
Median: Calculated by finding the middle value in a set of data, so the error in the highest score does not affect the median, as it will still be the fourth highest test score.
Minimum: The lowest test score remains the same, as it will not be affected by the error in the highest score.
Range: Calculated by subtracting the lowest test score from the highest score, so if the highest score is incorrect, the range will also be incorrect.
Therefore, only the maximum score and the range are altered by George's mistake, and the mean, median, and minimum score remain the same.

The area of triangle ABD is 50cm, and one of its sides is 10cm in length. Find one of the heights of the triangle.
Answers
Answer:
10cm
Step-by-step explanation:
If you want to find one of the heights of the triangle, you need to use some math magic. The magic spell is:
A = (1/2) * b * h
where A is the area, b is the base, and h is the height. Don't ask me why, it just works.
Now, we know that the area of triangle ABD is 50 cm and one of its sides is 10 cm. We can pretend that this side is the base of the triangle. Why? Because it makes our life easier. Trust me.
Then we put these numbers into the magic spell and we get:
50 = (1/2) * 10 * h
Now we need to solve for h, which is the height we want. To do that, we need to do some algebra. Don't worry, it's not that hard. Just follow these steps:
- Multiply both sides by 2. This gives us:
100 = 10 * h
- Divide both sides by 10. This gives us:
10 = h
- Celebrate! We found the height!
So, one of the heights of the triangle is 10 cm. Isn't math fun?
Area of triangle = 1/2 × base × height
We know the area of the triangle is 50 cm², and one of the sides (which is also the base) is 10 cm. Let's substitute these values in the formula and solve for the height:
50 = 1/2 × 10 × height
Multiplying both sides by 2, we get:
100 = 10 × height
Dividing both sides by 10, we get:
height = 10 cm
Therefore, the height of triangle ABD is 10 cm.

Julia wants to put $56,000 into a savings account for 8 years and increase her total to at least $100,000. Assuming the interest is not compounded, what rate of return does the account need to earn?
Answers
Answer:
the account needs to earn a rate of return of at least 9.82% per year to increase Julia's total to $100,000 in 8 years with simple interest.
Step-by-step explanation:
To find the rate of return that the account needs to earn, we can use the simple interest formula:
Simple Interest = Principal x Rate x Time
Where:
- Principal = $56,000
- Time = 8 years
- Simple Interest = $100,000 - $56,000 = $44,000
Plugging in the values, we get:
$44,000 = $56,000 x Rate x 8
Simplifying the equation, we get:
Rate = $44,000 / ($56,000 x 8) = 0.0982 or 9.82%
Therefore, the account needs to earn a rate of return of at least 9.82% per year to increase Julia's total to $100,000 in 8 years with simple interest.
Answer: 9.82%
Step-by-step explanation:
So first of all we need to put down our formulae. We know that:
Simple interest = Principal × Time× Rate / 100
However the question is looking for Rate , therefore we must re -arrange the equation and make Rate the subject . This will give us :
Rate= Interest × 100 / Time × Principal
Now , the question tells us that the Principal is $56,00 and the time is 8 years , but we do not know the interest. In the case , we will use the equation :
interest =Amount -Principal to find the interest ,since the total amount has been given to us.
100,000 - 56,000 = 44,000
Principal =56,000
Time = 8
Interest=44,000
Using the first formulae:
44,000×100 / 8×56,000 = 9.8
Rate is always in % so our answer is 9.82%
