Answer:
Multiply by 3 on both sides of the equation.2.78 × 3 = 8.34, so t = 8.34.Substitute 8.34 for t to check the solution.
Step-by-step explanation:
Given equation:
[tex]\sf \dfrac{t}{3}=2.78[/tex]
Multiply by 3 on both sides of the equation:
[tex]\implies \sf \dfrac{t}{3} \times 3=2.78 \times 3[/tex]
[tex]\implies \sf t=8.34[/tex]
Substitute 8.34 for t to check the solution:
[tex]\implies \sf \dfrac{8.34}{3}=2.78 \quad \leftarrow \: correct![/tex]
Answer:
Options 1, 4, and 5
Step-by-step explanation:
In order to solve an equation, the most key rule to remember is that whatever you do to one side, you must do the same to the other side.
This ensures that the equation will remain true.
In order to solve this given equation, we need to isolate the variable t.
We currently have:
t/3=2.78
To isolate t, we must "undo" dividing by 3.
The inverse of division is multiplication, so we can undo the operation by multiplying both sides of the equation by 3.
3 * t/3 = 2.78*3
Simplify
t=8.34
Since t=8.34, it is with this value that we should check the solution.
We can plug 8.34 in for t to see if the equation is true.
8.34/3=2.78
2.78=2.78
Since this is true, we know that we have solved the equation correctly.

Estimate the sum: 1 3/7 + 3 5/9 + 1/2. Show your work.
Answers
Answer:
The correct answer is 5 61/126!
Step-by-step explanation:
Leave a fraction alone
1 3/7
Find the Addend
9x3=27+5=32 = 32/9
Find the sum and simplify
1 3/7 + 32/9 = 691/126 = 5 61/126
To estimate the sum of the given terms: 13/7, 35/9, and 1/2, we can convert each term to a decimal number and then add them together. First, let's convert 13/7 to a decimal.
To do this, we divide [tex]13 by 7: 13 ÷ 7 = 1.857[/tex] Next, let's convert 35/9 to a decimal. Dividing 35 by 9 gives us: [tex]35 ÷ 9 = 3.889[/tex] Finally, we convert 1/2 to a decimal by dividing 1 by 2:[tex]1 ÷ 2 = 0.5[/tex] Now that we have converted all the terms to decimals, we can add them together: [tex]1.857 + 3.889 + 0.5 = 6.246[/tex]
Therefore, the estimate of the sum of the given terms is 6.246. It's important to note that this is an estimate because we rounded the decimal values. If you need a more precise answer, you can use a calculator or longer division to get more decimal places. However, for most practical purposes, this estimate should suffice.

A store is giving out cards labeled 1 through 10 when customers enter the store. If the card is an even number, you get a 15% discount on your purchase that day. If the card is an odd number greater than 6, you get a 40% discount. Otherwise, you get a 25% discount. The table shows the results of 400 customers. What is the relative frequency for each discount? Use pencil and paper. If the manager of the store wants approximately half of the customers to receive the 25% discount, does this seem like an appropriate method?
Answers
Answer:
The answer would be A. 1 1/5
48/40 = 1 8/40
1 8/40 Simplify to 1 1/5
Step-by-step explanation:
If the store wants to give approximately half of the customers a 25% discount. They may need to adjust the discount criteria or randomly assign cards to customers to achieve the desired frequency.
What is the relative frequency?The ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space, but in an actual experiment, is the relative frequency or experimental probability of an event.
To determine the relative frequency for each discount, we need to count the number of customers who received each type of discount and divide by the total number of customers.
Let's create a table to organize the data:
Discount Card Label Number of Customers
15% Even 120
40% Odd > 6 30
25% Other 250
Total 400
The relative frequency for each discount is given by:
Relative frequency of 15% discount: 120/400 = 0.3 or 30%
Relative frequency of 40% discount: 30/400 = 0.075 or 7.5%
Relative frequency of 25% discount: 250/400 = 0.625 or 62.5%
To determine whether this discount method is appropriate to give approximately half of the customers a 25% discount, we need to compare the observed frequency of the 25% discount with the desired frequency.
Half of the 400 customers is 200. If we want approximately half of the customers to receive the 25% discount, then the observed frequency of the 25% discount should be close to 200.
However, we see that the observed frequency of the 25% discount is 250, which is higher than the desired frequency.

what is the mean absolute deviation of the data set below?
3,1,4,4,4,1,1,2,1,5
Answers
Answer:
1.4
Step-by-step explanation:
Step 1: We have to find the mean of the data set
The mean is the average or the sum of all the numbers divided by the amount of numbers there are.
3 + 1 + 4 + 4 + 4 + 1 + 1 + 2 + 1 + 5 = 26
There are 10 numbers in total so, 26/10 = 2.6
Step 2: We now know the mean so now we have to find the deviation
3 - 2.6, |1 - 2.6|, 4 - 2.6, 4 - 2.6... so on, (Note: this is just finding the distance between the numbers and the mean)
The results are, 0.4 + 1.6 + 1.4 + 1.4 + 1.4 + 1.6 + 1.6 + 0.6 + 1.6 + 2.4
This is equal to 14
Step 3: Lastly, we have to find the mean of the deviations
We know the mean is 14
We have 10 numbers
Therefore, 14/10 = 1.4 is the MAD
