Answer:
Variance of this population = 9,409
Step-by-step explanation:
Given:
Standard deviation of population = 97
Random sample size = 26
Find:
Variance of this population
Computation:
Standard deviation (σ) = 97
Variance = Standard deviation²
Variance = (σ)²
Variance of this population = Standard deviation of population²
Variance of this population = 97²
Variance of this population = 9,409

Which expression has a greater value: log^3 1/3 or log ^b 1/b? Explain how you know.
The value of both the logarithmic expressions is equal which is equal to the negative one.
What is a logarithm?Logarithms are another way of writing exponent. A logarithm with a number base is equal to the other number. It is just the opposite of the exponent function.
The expressions are given below.
[tex]\log _3 \dfrac{1}{3} \ and \ \log _b \dfrac{1}{b}[/tex]
This can be written as
[tex]\log _3 3^{-1} \\\\\log _bb^{-1}[/tex]
We know that the property of the logarithm
[tex]\log _a a = 1\\\\\log a^b = b\log a[/tex]
Then we have
[tex]\log _3 3^{-1} = -1 \log _33 = -1\\\\\log _bb^{-1} = -1 \log _bb = -1\\[/tex]
The value of both the expressions is equal which is equal to the negative one.

To find the solution to a system of linear equations, Verdita begins by creating equations for the two sets of data points below.
Data Set A
A 2-column table with 4 rows. Column 1 is labeled x with entries negative 1, 1, 5, 7. Column 2 is labeled y with entries negative 6, 2, 18, 26.
Data Set B
A 2-column table with 4 rows. Column 1 is labeled x with entries negative 5, negative 2, 0, 6. Column 2 is labeled y with entries negative 1, 2, 4, 10.
Which equations could Verdita use to represent the data sets?
Data Set A: y = 4 x minus 2
Data Set B: y = x + 4
Data Set A: y = 4 x minus 2
Data Set B: y = x minus 4
Data Set A: y = 4 x + 2
Data Set B: y = x minus 4
Data Set A: y = 4 x + 2
Data Set B: y = x + 4
Answer:
The answer to this question would be A Data Set A: y = 4x - 2 Data Set B: y = x + 4
Answer:

The manager of a cafeteria kept track of the number of each type of lunch sold in October and made this table. Which graph
best correctly and completely represents the data in the table?
Answer:
The third one.
Step-by-step explanation:
The first graph says each square is 10 lunches, but there are only 3 squares for the deli sandwich. That's 30 deli sandwiches in total but there were 300 in the table so the first one is wrong. In the second one, it says that 2 types of lunches were sold up to 300 times, but in the table, only 1 was. The last graph says that there were 300 pizzas sold, but the table said there were 650, so that one is wrong.
Process of elimination leaves you with the third graph as the correct answer.
