Ratio table can help you find equivalent ratios in order to solve problems.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Ratio tables show equivalent ratios between two quantities. You can create a ratio table by multiplying (or dividing) both quantities in the ratio by the same value to find an equivalent ratio.
A ratio table can help you find equivalent ratios in order to solve problems.
If a straight line passing through the origin has same ratios or which has same slope at all points.
Hence, ratio table can help you find equivalent ratios in order to solve problems.

how do you find the average rate of change of the profit for a product?
Answer:
The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
Step-by-step explanation:
5/2÷9/4_________________
Remember, the trick to dividing fractions is to use keep/change/flip.
First, keep your 5/2 the same. Second, change your division sign to a multiplication sign. Third, flip your 9/4 to get 4/9. Multiply!
Mixed number form: 1 1/9

Find the rate of ounces of water needed for each packet of flavoring
Answer:
24 ounces/ 2 packets = 12 ounces/ packet
Step-by-step explanation:
23 (12 ounces/packet) = 276 ounces of water
The the rate of ounces of water needed for each packet of flavoring would be 12.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.equation modelling : Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problemGiven is the packets of flavoring added to an specific amount of water to make soup.
Now, for 24 ounces of water, 2 packets of flavoring are needed.
Then, for 1 packet of flavoring, (24/2) or 12 ounces of water is needed.
For 5 packets of flavoring, (12 x 5) or 60 ounces of water is needed.
So, the rate of ounces of water needed for each packet of flavoring would be -
r = (60 - 24)/(5 - 2)
r = 36/3
r = 12
r = 12
Therefore, the the rate of ounces of water needed for each packet of flavoring would be 12.

Which of the following numbers is/are positive ?
1
(A) In 2 + In 3 + In 0.161
(B) In 3 + In(1.4) - In 16
Answer:
Neither expression (A) nor expression (B) would be positive. A calculator is not required.
Step-by-step explanation:
Assume that [tex]A[/tex] and [tex]B[/tex] are both positive real numbers. Consider the property of logarithms with the same base:
[tex]\ln A + \ln B = \ln(A \cdot B)[/tex].
[tex]\displaystyle \ln A - \ln B = \ln\left(\frac{A}{B}\right)[/tex].
Apply these two properties to combine the logarithms in each expression into a one.
First expression:
[tex]\begin{aligned}&\ln 2+ \ln 3 + \ln 0.161 \\ &= \ln(2 \times 3) + \ln (0.161) \\ &= \ln(2 \times 3 \times 0.161) = \ln(0.966) \end{aligned}[/tex].
Second expression:
[tex]\begin{aligned}&\ln 3+ \ln (1.4) - \ln 16 \\ &= \ln(3 \times 1.4) - \ln (16) \\ &= \ln\left(\frac{3 \times 1.4}{16}\right) = \ln(0.2625) \end{aligned}[/tex].
The logarithm of a real number is positive if and only if that number is greater than one.
Neither [tex]0.966[/tex] nor [tex]0.2625[/tex] is greater than one. Therefore, neither of their respective logarithms would be positive.

11. There are 300 and 250 cows on Farms A and B respectively. How
many cows from Farm A must be transferred to Farm B so that the
number of cows on Farm B is four times the number of cows on
Farm A?
Answer:
I think it's twenty five
Answer:
190
Step-by-step explanation:
we want 1/5 on farm A and 4/5 of cows on farm B.
[tex] \frac{(300+250)}{5} = \frac{550}{5} = 110[/tex]
110 cows is 1/5. 550-110=440 and 440 is 4/5.
we want 110 cows on farm A and 440 on farm B.
So, there already is 250 cows on farm B and we need to move 440-250=190 cows from farm A to farm B.
And you can check that 4*110=440

Suppose a population has a mean happiness score of 75 and a standard deviation of 15. Researcher A takes a random sample of 100 participants. Researcher B takes a random sample of 25 participants. Which researcher is more likely to get a sample mean of 80 or higher
Answer:
Researcher A is more likely to get a sample mean of 80 or higher
Step-by-step explanation:
The central limit theorem states that if the sample size increases the sampling distribution of the mean approaches normal distribution.The z score would be given by
z= x`- ux/ (σx/√n)
The sample standard deviation is given by 15 / √25 = 3 and 15 / √100 = 1.5
z=75-ux/3/5
Suppose z= 1.96
1.96 = 75 - ux /0.6
1.176- 75= -ux
ux = 73.824
Now Putting values for the second sample
z=75-ux/1.5/10
Suppose z= 1.96
1.96 = 75 - ux /0.15
0.2904- 75= -ux
ux = 74.706
From the above we see that the larger sample size would give a sample mean equal to the population mean .
What is the rate in teaspoons of toasted sesame seeds per teaspoon of pepper flakes?

Step-by-step explanation:
12 tsp of toasted sesame seeds per teaspoon of pepper flakes
What is Fraction?A fraction represents a part of a whole.
Given that Omar need 8 tsp of toasted sesame seed for 2/3 tsp of pepper flake.
We need to find the rate in teaspoons or toasted sesame seeds per teaspoon of pepper flakes.
Based on the given conditions, formulate:
We need to find Eight divided by the fraction two by three.
8/(2/3)
When a whole number is divided by a fraction then the multiply the whole number by the reciprocal of the fraction.
8×3/2
When eight is multiplied with 3 is 24.
24/2
Divide numerator and denominator by 2
We get twelve,12
Hence, 12 tsp of toasted sesame seeds per teaspoon of pepper flakes
