Predict if the product will be greater than, less than or equal to the second factor 4/5 x 1 2/5 = y
Answers
Answer:
The product will be less than the second factor.
Step-by-step explanation:
Given the expression
\(\frac{4}{5}\:\times \:1\frac{2}{5}\:=y\)
solving to determine the product value
\(y=\:\frac{4}{5}\times \:\:1\frac{2}{5}\)
\(=\frac{4}{5}\times \frac{7}{5}\)
\(\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}\)
\(=\frac{4\times \:7}{5\times \:5}\)
\(=\frac{28}{5\times \:5}\)
\(=\frac{28}{25}\)
As the value of the second factor is:
\(1\frac{2}{5}=\frac{7}{5}=1.4\)
And the product value is:
\(y=\frac{28}{25}=1.12\)
It is clear that the product value 'y = 1.12' is lesser than the second factor value '1.4'.
i.e. 1.12 < 1.4
Thus, the product will be less than the second factor.

Susan is attending a talk at her sons school. There are 8 rows of 10 chairs where 54 parents are sitting. Susan noticed that every parent is either sitting on their own or next to one other person. What is the largest possible number of adjacent empty chair in a single row? 3 4 5 7 8
Answers
Answer: 4
Step-by-step explanation:
To fit the maximum amount of people in one row, you would have 3 couples and 1 single = 7 parents.
If we continue the maximum amount of people for 7 rows, we get 49 parents seated.
Since a total of 54 parents are seated, that leaves 54 - 49 = 5 parents remaining to be seated in the last row. These parents can be seated as 2 couples and 1 single. If you put the single at the end of the row, there will be 4 seats between the couple and the single.

Organize the following data in a stem-and-leaf plot.

184 196 185 174 186 197 170
178 179 182 193 195 171
b) Use your stem-and-leaf plot to determine the median and the mode.
C)Calculate the mean of the data.
Answers
```
15 | 1
17 | 0 0 1 4
18 | 2 4 5 6 6
19 | 3 4 5 6 7 9
```
b) To find the median, we need to put the data in order from least to greatest:
```
151 170 170 171 174 178 179 182 184 185 186 186 186 193 194 195 196 197 199 219
```
There are 20 numbers in the data set, so the median is the average of the 10th and 11th numbers:
```
Median = (185 + 186) / 2 = 185.5
```
To find the mode, we look for the most common value in the data set. In this case, the stem-and-leaf plot shows that there are two modes: 186 and 170.
c) To calculate the mean, we add up all the numbers and divide by the total number of numbers:
```
Mean = (219 + 151 + 199 + 186 + 170 + 186 + 194 + 184 + 196 + 185 + 174 + 186 + 197 + 170 + 178 + 179 + 182 + 193 + 195 + 171) / 20
Mean = 1849 / 20
Mean = 92.45
```
Therefore, the mean of the data is 92.45.

What is at 6% interest And what is at 14% interest
Answers
The rule of the simple interest is
\(I=\text{PRT}\)P is the initial amount
R is the rate in decimal
T is the time
Let her put $x in the account of 6%, and $y in the account of 14%
Since the amount in the 14% is more by 900, then
\(y=x+900\rightarrow(1)\)Let the first account has I1 interest and the second amount has I2 interest
\(I_1=x(R_1)(1)\)Since R1 = 6%
Change it to decimal by dividing it by 100
\(R_1=\frac{6}{100}=0.06\)Then
\(\begin{gathered} I_1=x(0.06)(1) \\ I_1=0.06x \end{gathered}\)Since R2 = 14%, then
\(\begin{gathered} I_2=y(\frac{14}{100})(1) \\ I_2=0.14y \end{gathered}\)Since the total interest is $209, then add I1 and I2 and equate the sum by 209
\(0.06x+0.14y=209\rightarrow(2)\)Substitute y in equation (2) by equation (1)
\(0.06x+0.14(x+900)=209\)Simplify the left side
\(\begin{gathered} 0.06x+0.14(x)+0.14(900)=209 \\ 0.06x+0.14x+126=209 \end{gathered}\)Add the like terms on the left side
\(\begin{gathered} (0.06x+0.14x)+126=209 \\ 0.2x+126=209 \end{gathered}\)Subtract 126 from both sides, then divide the 2 sides by 0.2 to find x
\(\begin{gathered} 0.2x+126-126=209-126 \\ 0.2x=83 \\ \frac{0.2x}{0.2}=\frac{83}{0.2} \\ x=415 \end{gathered}\)Substitute x in equation (1) by 415
\(\begin{gathered} y=900+415 \\ y=1315 \end{gathered}\)6% is $415
14% is $1315

Find the number that makes the ratio equivalent to 3:4

You are given that z > 2. Write an inequality for each expression.
a) 2z+ 9
b) 3(z - 4)
c) 4+2z
d) 5(3z-2)
Answers
a) The inequality for the expression 2z + 9 is 2z + 9 > 13.
b) The inequality for the expression 3(z - 4) is 3z - 12 > -6.
c) The inequality for the expression 4 + 2z is 4 + 2z > 8.
d) The inequality for the expression 5(3z - 2) is 15z - 10 > 20.
a) To write an inequality for the expression 2z + 9, we can multiply the given inequality z > 2 by 2 and then add 9 to both sides of the inequality:
2z > 2 * 2
2z > 4
Adding 9 to both sides:
2z + 9 > 4 + 9
2z + 9 > 13
Therefore, the inequality for the expression 2z + 9 is 2z + 9 > 13.
b) For the expression 3(z - 4), we can distribute the 3 inside the parentheses:
3z - 3 * 4
3z - 12
Since we are given that z > 2, we can substitute z > 2 into the expression:
3z - 12 > 3 * 2 - 12
3z - 12 > 6 - 12
3z - 12 > -6
Therefore, the inequality for the expression 3(z - 4) is 3z - 12 > -6.
c) The expression 4 + 2z does not change with the given inequality z > 2. We can simply rewrite the expression:
4 + 2z > 4 + 2 * 2
4 + 2z > 4 + 4
4 + 2z > 8
Therefore, the inequality for the expression 4 + 2z is 4 + 2z > 8.
d) Similar to the previous expressions, we can distribute the 5 in the expression 5(3z - 2):
5 * 3z - 5 * 2
15z - 10
Considering the given inequality z > 2, we can substitute z > 2 into the expression:
15z - 10 > 15 * 2 - 10
15z - 10 > 30 - 10
15z - 10 > 20
Therefore, the inequality for the expression 5(3z - 2) is 15z - 10 > 20.

Whenever Deven and Laura owe each other money, they "pay" each other using stickers. They've agreed that a Harry Potter sticker is worth 49 dollars and a Twilight sticker is worth 35 dollars. They can even use stickers as "change" if one person overpays the other. For example, if Deven owes Laura 189 dollars, he can give her 6 Harry Potter stickers ($6 \cdot 49 = 294$ dollars), and she can return 3 Twilight stickers ($3 \cdot 35 = 105$ dollars). This trade is like a transfer of $294-105=189$ dollars. What is the smallest positive debt, in dollars, that can be paid off using sticker trading?
Answers
The smallest positive debt that can be paid off using sticker trading is $7$ dollars.
To find the smallest positive debt that can be paid off using sticker trading, we need to consider the values of the stickers (in dollars) and find the smallest positive amount that can be reached through a combination of these values.
Given that a Harry Potter sticker is worth $49 and a Twilight sticker is worth $35, we can approach this problem using the concept of the greatest common divisor (GCD) of these two values.
The GCD of $49$ and $35$ is $7$. This means that any multiple of the GCD can be represented using these sticker values.
In other words, any positive multiple of $7$ dollars can be paid off using sticker trading.
Therefore, the smallest positive debt that can be paid off using sticker trading is $7$ dollars.

If the anticipated claim outcome actually occurs, it will either be possible to contact the variable again or both important processes will undoubtedly miss the statement.
Here,
We must convert cups to gallons because daisy cream is sold in bulks of cups. Since a gallon of Daisy cream comprises 16 cups, one quantity of Daisy cream contains:
=> 16 cups per bulk = 1 gallon 16 cups per bulk = 1 gallon
Moscow cream is offered in bulk quantities of 4 1/2 gallons, which is one gallon.
Thus, we must convert pints to gallons. A gallon of Marble cream comprises eight pints, hence one quantity of Marble cream contains:
=> 40 pints in a bulk equal 1 gallon, 8 pints, or 5 gallons.
As a result, we can see that Marble cream, with 5 gallons per bulk, has the most cream.
Daisy cream and Kremlin cream both have less cream per bulk (1 gallon and 4.5 gallons, respectively) than Marble cream.

Answers
The standard deviation is 1.43 below the mean
How to determine the number of standard deviation?The given parameters are:
Mean = 98.249
Standard deviation = 0.733
x = 97.2
To calculate the number of standard deviation below the mean, we use
\(x = \bar x - n\sigma\)
So, we have:
\(97.2 = 98.249 - n * 0.7333\)
Evaluate the like terms
\(-1.049 =- n * 0.7333\)
Divide both sides by -0.733
n =1.43
