Answer:
36 units
Step-by-step explanation:
If half of one of the 6 sections is three the the other half is equivalent so I multiplied 6×6 and it gave me 36 (units).
Answer:
Given :An Internet survey was e-mailed to 6977 subjects randomly selected from an online group involved with ears. There were 1337 surveys returned.
To Find : Use a 0.01 significance level to test the claim that the return rate is less than 20%.
Solution:
n = 6977
x = 1337
We will use one sample proportion test
We are given that the claim is the return rate is less than 20%.
Formula of test statistic =
=
=
Refer the z table
P(z<-1.85)=0.0332
Significance level = 0.01=α
Since p value > α
So, we accept the null hypothesis .
So,the claim that the return rate is less than 20% is false.
Answer:
The correct options are;
1) The functions are inverse of each other and
3) The graphs of the functions are symmetric to each other over the line y = x
Step-by-step explanation:
Here we have
y = 2ˣ and y = log₂x
We are to analyze each of the options as follows;
1) The functions are inverse of each other
The above statement is correct as the inverse of y = 2ˣ is x = therefore y = log₂x is inverse of y = 2ˣ
2) The graphs of the functions are symmetric about the line y = 0
The above statement is not correct as the line y = 0 is the x axis whereby y = 1 and y = -1 give x = 5 and x = 0.5 respectively
3) The graphs of the functions are symmetric to each other over the line y = x
The line y = x is a straight line with slope = 1 whereby since x > log₂x, and y > log₂y then the two lines are symmetric
4) The equation y=log₂x is the logarithmic form of y=2ˣ .
The above statement is not correct as log2ˣ = x log2 ≠ log₂x.
Answer:
Option D [] in the list of possible answers
Step-by-step explanation:
For this problem you are supposed to use a calculator that allows you to do an exponential regression. There are many tools that can help you with that, depending on what your instructors has assigned for your class.
I am showing you the results of a graphing tool I use, and which after entering the x-values and the y-values in independent "List" forms, when I request the exponential regression to fit the data, I get what you can see in the attached image.
Notice that the exponential of best fit with my calculator comes in the form:
with optimized parameters:
Notice as well that since:
the exponential best fit can also be written:
and this expression is very close to the last option shown in your list of possible answers
<span>A) x - y = 11
B) 2x +y =19
Multiplying equation A) by -2
A) -2x + 2y = -22 then we add it to B)
B) 2x + y = 19
3y = -3
y = -1
x = 10
