logc (xy^6z^-4) what is the equivalent expression
By eliminating exponents, the logarithmic expression [tex]\log_{c} x\cdot y^{6}\cdot z^{-4}[/tex] is equivalent to the logarithmic expression [tex]\log_{c} x + 6\cdot \log_{c} y - 4\cdot \log_{c} z[/tex].
How to simplify logarithmic functions
In this problem we are supposed to eliminate all exponents of a logarithmic function by applying any of the following properties:
㏒ x · y = ㏒ x + ㏒ y㏒ x/y = ㏒ x - ㏒ y㏒ yˣ = x · ㏒ yNow, we proceed to simplify the function:
[tex]\log_{c} x\cdot y^{6}\cdot z^{-4}[/tex]

State the decision rule.
Compute the value of the test statistic.
What is your decision regarding H0?

1) This is a Two tailed Test.
2) Decision rule is; If the p-value is greater than 4% fail to reject H₀.
3) P-value = 0.00968764 and so we reject H₀
How to state the decision rule in hypothesis testing?We are given the hypothesis as;

A store is having a sale on chocolate chips and walnuts. For 5 pounds of chocolate chips and 3 pounds of walnuts, the total cost is $25 . For 7 pounds of chocolate chips and 9 pounds of walnuts, the total cost is $53 . Find the cost for each pound of chocolate chips and each pound of walnuts.
Answer:
one pound of chocolate chips = $2.75
one pound of walnuts = $3.75
Step-by-step explanation:
we can solve this by first making an equation
let's write the number of chocolate chips in c
and the number of walnuts in w
5c + 3w = 25
7c + 9w = 53
let's first solve for c by multiplying the top equation by 3 and subtracting the bottom equation from it
(15c + 9w = 75) - (7c + 9w = 53)
8c = 22
c = $2.75
Let's now start to solve for w by inputting c into one of the equations.
(2.75)7 + 9w = 53
19.25 + 9w = 53
9w = 53 - 19.25
9w = 33.75
w = $3.75
a pound of chocolate chips = 2.75
a pound of walnuts = 3.75
give me brainliest, please!
Hope this helps :)
Answer:
each pound of chocolate chips costs $2.75
each pound of walnuts costs $3.75
Step-by-step explanation:
let c be the cost of a pound of chocolate chips
and w be the cost of a pound of chocolate chips
For 5 pounds of chocolate chips and 3 pounds of walnuts,
the total cost is $25 means 5c + 3w = 25
For 7 pounds of chocolate chips and 9 pounds of walnuts,
the total cost is $53 means 7c + 9w = 53
Now we have to solve the system:
[tex]\begin{cases}5c+3w=25&\\ 7c+9w=53&\end{cases}[/tex]
[tex]\Longleftrightarrow \begin{cases}15c+9w=75&\\ 7c+9w=53&\end{cases}[/tex]

Which exponential function has the greatest average rate of change over the interval [0, 2]?
OA j(x) = 3(1.6)²
OB. An exponential function, f, with a y-intercept of 1.5 and a common ratio of 2.
OC.
OD.
g(x)
k(x)
The function with the greatest average rate of change is the function k(x)
How to determine the function?The average rate of change is calculated as
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
The interval is [0,2].
So, we have
[tex]m = \frac{y_2 - y_1}{2 -0}[/tex]
[tex]m = \frac{y_2 - y_1}{2}[/tex]
For function j(x), we have
j(2) = 3 * 1.6^2 = 7.68
j(2) = 3 * 1.6^0 = 3
So, we have
[tex]m_j = \frac{7.68 - 3}{2}[/tex]
[tex]m_j = 2.34[/tex]
For function g(x), we have
g(2) = 25/2
g(0) = 8
So, we have
[tex]m_g = \frac{25/2 - 8}{2}[/tex]
[tex]m_g = 2.25[/tex]
For function k(x), we have
k(2) = 9
k(0) = 4
So, we have
[tex]m_k = \frac{9 - 4}{2}[/tex]
[tex]m_k = 2.5[/tex]
For function f(x), we have
f(2) = 1.5 * 2^2 = 6
f(0) = 1.5
So, we have
[tex]m_f = \frac{6 - 1.5}{2}[/tex]
[tex]m_f = 2.25[/tex]
The function with the greatest average rate of change is the function k(x) with a rate of 2.5
