Answer:
1. 55.23 2. 52.31 3. 27.49 4. 347.05 5. 7.57
Step-by-step explanation:
Pretty self explanatory when viewing my answers, there is no trick question within this problem, you simply add 10 to the first 3 numbers, but leave the range and standard deviation the same.
Mean = $55.23
Median = $52.31
Mode = $27.49
Range = $347.05
Standard Deviation = $7.57
What are measures Central Tendency?Mean: The mean represents the average value of the dataset.
Median: Median is the middle value of the dataset in which the dataset is arranged in the ascending order or in descending order.
Mode: The mode represents the frequently occurring value in the dataset.
Range: Range is the difference between the largest and smallest value in the data set
Standard Deviation: Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists.
Given, information about online purchases:
Mean = $45.23
Median = $42.31
Mode = $17.49
Range = $347.05
Standard Deviation = $7.57
After adding Shipping Charge of $10 to each purchase:
Since $10 is added to each value then,
New Mean = (∑x + n($10) )/n = ∑x/n + n ($10)/n
New Mean = $45.23 + 10
New Mean = $55.23
To find median, $10 will be added to the value of median.
New Median = $42.31 + $10
New Median = $52.31
To find mode, $10 will be added to the value of mode.
New Mode = $17.49 + $10
New Mode = $27.49
Range and Standard Deviation don't change if we add same value to each data point, It will remain same.
New Range = $347.05
New Standard Deviation = $7.57
Hence, the new mean, new median and new mode are $10 increased than the original ones, there is no change in value of range and standard deviation.

which is greater 2/3 5/10 7/8 1/2 ?
Answer:
2/3 5/10 7/8 1/2
Step-by-step explanation:
hello :
2/3 =(2×8)/(3 ×8) = 16/24
5/10 = 1/2= (1×12)/(2 ×12)=12/24
7/8= (7×3)/(8 ×3)= 21/24
the greater is : 7/8
To determine which of the fractions 2/3, 5/10, 7/8, and 1/2 is the greatest, we must first convert the fractions to decimals. Once converted, 7/8 (0.875) is the highest decimal value, thereby making it the greatest fraction.
Explanation:To figure out which is greater among 2/3, 5/10, 7/8 and 1/2, we need to convert each of these fractions into decimals because it is easier to compare decimals than fractions.
So, 2/3 = 0.6667, 5/10 = 0.5, 7/8 = 0.875 and 1/2 = 0.5.
Comparing these decimals, it is clear that 7/8 (which equals to 0.875) is the greatest among the four.

The length of a field, 1.2 km long is represented on a map by a line 40mm long. What is the scale of the map
Final answer:
The scale of the map is 1:30,000.
Explanation:
The scale of a map represents the relationship between the distance on the map and the corresponding distance on the Earth's surface. To find the scale of the map, we need to determine the ratio between the length of the field on the map and its actual length. In this case, the length of the field is 1.2 km, which is represented on the map by a line that is 40 mm long.
To calculate the scale, we can use the formula:
Scale = Actual length on the ground / Length on the map
Substituting the values, we get:
Scale = 1.2 km / 40 mm
First, we need to convert the length on the map to the same unit as the actual length. Since 1 km = 1,000,000 mm, we can convert mm to km by multiplying by 1/1,000,000:
Length on the map in km = 40 mm × (1 km / 1,000,000 mm) = 0.00004 km
Now we can calculate the scale:
Scale = 1.2 km / 0.00004 km = 30,000
Therefore, the scale of the map is 1:30,000.

there shop keepers go to a wholesaler to buy packets of mints. each shop small packets, medium packets and large packets of mints. Anne buys 600 packets of mints. 34% are small packets and 49% are large packets. Ben buys 400 packets of mints, 3/10 are small packets and 1/10 are large packets. Chas buys 210 small packets of mints so that number of small packets: number of medium packets = 3 : 4 work out the total number of medium packets of mints these shop keepers buy.
Answer:
medium 156+240+105=501
small 204 + 120=324
large 40+240 =280
Step-by-step explanation:
600 of what ever the percentage or the fraction to find each small and large also medium.
example = 600 x 34% =204
another example is 400 x 3/10 = 40
The total number of medium packets of mints bought by the three shopkeepers Anne, Ben and Chas is calculated to be 622, using ratios and percentages to determine the breakdown of packets bought.
Explanation:To solve this problem, we first find out the number of small, medium, and large packets each shopkeeper buys. For Anne, if 34% of 600 packets are small, she buys 0.34 * 600 = 204 small packets. Then, from the remaining packets 49% are large, which makes 0.49 * 600 = 294 large packets. The rest are medium packets, making 600 - 204 - 294 = 102 medium packets.
For Ben, 3/10 of his 400 packets are small, which makes 3/10 * 400 = 120 small packets. Also, 1/10 of his packets are large, hence 1/10 * 400 = 40 large packets. The rest, thus, are medium: 400 - 120 - 40 = 240 medium packets.
For Chas, if the ratio of small packets to medium packets is 3:4, meaning for every 3 small packets, there are 4 medium packets. She bought 210 small packets, thus for medium packets, using the ratio, it becomes 210 * (4/3) = 280 medium packets.
The total number of medium packets that these shopkeepers buy is thus: 102 + 240 + 280 = 622 medium packets.

A restaurant has 4 appetizers, 5 entrees and 2 desserts. How many different meal combinations could you order?
Step-by-step explanation:
1.) Firstly, you need to count out how many things there are. 4 app, 5 entrees, 2 desserts. This makes 11 different things
2.) for 11 numbers there can be 9 ways for each number for 1st nine places since 0 can't be the fist figure and next two are reciprocated from 10 numbers. Therefore 10!/2!
3.)So 99 combinations have 10!/2! Permutations hence total ways are 99*10!/2!

Step-by-step explanation:
On a winter day the low temperature in Anchorage, Alaska was -21 degrees Celsius and the low temperature in Minneapolis, Minnesota was -14 degrees Celsius. Jada said: “I know that 14 is less than 21, so -14 is also less than -21. This means that it was colder in Minneapolis than in Anchorage.” Do you agree? Explain your reasoning.
Jada's reasoning about the temperatures is incorrect because in negative numbers, the lower the value, the colder the temperature. Hence, Anchorage at -21°C was colder than Minneapolis at -14°C.
Explanation:Jada's statement that "-14 is also less than -21" is incorrect when referring to temperatures in degrees Celsius. In fact, when we work with negative numbers, especially temperatures, the higher the negative number, the warmer the temperature. That is, -14°C is warmer than -21°C. Therefore, it was actually colder in Anchorage, Alaska at -21°C compared to Minneapolis, Minnesota at -14°C. To understand this better, we can look at a thermometer or a number line where numbers to the right are higher (warmer) than those to the left.

Look at the attached picture ⤴
Hope it will help u...
Final answer:
To solve the equation 0.03x - 0.1 = 2.6, you add 0.1 to both sides and then divide by 0.03, resulting in the value of x being 90.
Explanation:
In the equation 0.03x - 0.1 = 2.6, to find the value of x, we first add 0.1 to both sides of the equation to isolate the term with x on one side. This gives us 0.03x = 2.7. Next, we divide both sides of the equation by 0.03 to solve for x, which gives us x = 2.7 / 0.03. Therefore, the value of x is 90.

A basketball with a diameter of 9.5 in. is placed in a cubic box with sides 15 in. long. How many cubic inches of packing foam are needed to fill the rest of the box? Round to the nearest tenth.
Answer:
2926.32 cubic inches
Step-by-step explanation:
Given the information:
A basketball with a diameter of 9.5 in=> its radius is: 9.5/2 = 4.75 in
As we know, the formula used to find the volume of the sphere is:
V =π [tex]\frac{4}{3} r^{3}[/tex]
=> the volume of the basketball is:
V = π [tex]\frac{4}{3} 4.75^{3}[/tex]
= 448.69 cubic inches
A cubic box with sides 15 inAs we know, the formula used to find the volume of a cube is:
V = [tex]a^{3}[/tex]
=> the volume of the box:
V = [tex]15^{3}[/tex] = 3375 cubic inches
Hence, The volume of foam there is needed to complete the box is the subtraction between the two volumes above:
= the volume of the box - the volume of the basketball
= 3375 - 448.69
= 2926.32 cubic inches
