Answer:
3.99 10-6
Step-by-step explanation:
This is simply the answer because if you multiply them all out this equation is the smallest number
Answer:
3.99*10^-6
Step-by-step explanation:
Anything taken to a negative power is going to be smaller than the original number because x^-y=1/(x^y). So since 3.99*10^-6 is smaller than 4.4*10^-5, the former is the answer.

For which values of the parameter B the following system admits a unique solution [ 1 b 1-b 2 2 0 2–2B 4 0] [x y z] = [1 2 0]
Answer: β ≠ ±1
Step-by-step explanation: For a system of equations to have an unique solution, its determinant must be different from 0: det |A| ≠ 0. So,
det [tex]\left[\begin{array}{ccc}1&\beta&1-\beta\\2&2&0\\2-2\beta&4&0\end{array}\right][/tex] ≠ 0
Determinant of a 3x3 matrix is calculated by:
det [tex]\left[\begin{array}{ccc}1&\beta&1-\beta\\2&2&0\\2-2\beta&4&0\end{array}\right]\left[\begin{array}{ccc}1&\beta\\2&2\\2-2\beta&4\end{array}\right][/tex]
[tex]8(1-\beta)-[2(2-2\beta)(1-\beta)][/tex]
[tex]8-8\beta-4+8\beta-4\beta^{2}[/tex]
[tex]-4\beta^{2}+4\neq 0[/tex]
[tex]\beta^{2}\neq 1[/tex]
[tex]\beta \neq \sqrt{1}[/tex]
β ≠ ±1
For the system to have only one solution, β ≠ 1 or β ≠ -1.
Find the derivative F(x)=(5x+3)(2x^2+1)
Answer:
10x^3 + 6x^2 + 5x + 3
Step-by-step explanation:
F(x)=(5x+3)(2x^2+1)
= 5x*2x^2 + 5x*1 + 3*2x^2 + 3*1
= 10x^3 + 5x + 6x^2 + 3
= 10x^3 + 6x^2 + 5x + 3
Jeff can walk comfortably at 2.25 miles per hour. Find a linear equation that represents the total distance Jeff can walk in t hours, assuming he doesn't take any breaks.
The linear equation that represents the total distance Jeff can walk in t hours is d = 2.25t
How to find a linear equation that represents the total distance Jeff can walk in t hours?The given parameters are
Speed = 2.25 miles per hour
The linear equation that represents the total distance (d) Jeff can walk in t hours is calculated as:
d = Speed * t
This gives
d = 2.25 * t
Evaluate

Chang Industries has bonds outstanding with a par value of $210,400 and a carrying value of $218,600. If the company calls these bonds at a price of $214,000, the gain or loss on retirement is:
Answer:
The loss is $4600.
Step-by-step explanation:
The par value of the bonds = $210400
The carrying value of the bonds or the actual value of bonds = $218600
The company calls the bonds at the price = $214000
Now have to find the gain or loss from the given information. Thus, below is the calculation to find the gain or loss.
Loss or gain on retirement = $214,000 - $218,600 = -$4,600
Thus the loss on retirement is $4600.

1. Solve the shape equation puzzle?
Answer:
circle = 5, triangle = 2, square = 6
Step-by-step explanation:
If we look at the first and second equations, we see that circle + triangle + square = 13. Because triangle + square = 8, we can substitute this into the first equation, therefore, circle + 8 = 13 and circle = 5. Next, looking at the third equation, we see that circle + triangle = 7 and since circle = 5 we know that 5 + triangle = 7, therefore, triangle = 2. Finally, we can substitute triangle = 2 into the second equation which gives us 2 + square = 8, therefore, square = 6.

What is the degree of freedom associated with this t test.9. The p value associated with the t value isa. less than .05b. greater than .05c. I have no idea10. Based on your calculations, would you reject the null hypothes that there is no difference between males and females on this recognition task?a. Yes, I would reject the null hypothesis.b. No, I would not reject the null hypothesis.c. I have no idea.
Answer:
Reject the null hypothesis that there is no difference between males and females on the recognition task.
Step-by-step explanation:
Use MS-Excel to compute the required values.
Consider the data for male subjects first:
Mean = [tex]\frac{1}{20}\sum X_{m}}=5.85[/tex] SD = [tex]\sqrt{\frac{1}{20-1}\sum (X_{m}-\bar X_{m})^{2}}=1.69[/tex] SEM = [tex]\frac{SD}{\sqrt{20}}=0.38[/tex]Consider the data for female subjects:
Mean = [tex]\frac{1}{20}\sum X_{f}}=8.15[/tex] SD = [tex]\sqrt{\frac{1}{20-1}\sum (X_{f}-\bar X_{f})^{2}}=0.93[/tex] SEM = [tex]\frac{SD}{\sqrt{20}}=0.21[/tex]Use the Data Analysis tool in Excel to perform the hypothesis test.
The hypothesis can be defined as follows:
H₀: There is no difference between the two responses, i.e.[tex]\mu_{m}-\mu_{f}=0[/tex] .
Hₐ: There is a significant difference between the two responses, i.e.[tex]\mu_{m}-\mu_{f}\neq 0[/tex] .
Consider the Excel output for the hypothesis test.
The test statistic value is:
t = -5.32
The degrees of freedom is:
df = 38
The p value associated with the t value is:
p-value = 4.91025E-06 < 0.05
As the p-value is less than the significance level the null hypothesis will be rejected.
Conclusion:
Reject the null hypothesis that there is no difference between males and females on the recognition task.

How to get this answer:
Replace C with 25. Then evaluate (use the order of operations PEMDAS)
F = (9/5)*C + 32
F = (9/5)*25 + 32
F = 1.8*25 + 32
F = 45 + 32
F = 77
25 degrees Celsius is equal to 77 degrees Fahrenheit
So it is 77°F in Greensboro, NC.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
We know °F = (9/5)C + 32 converting unit of temparature to farhenhite.
Given, It is currently 25°C in Greensboro, NC.
∴ It is °F = (9/5)×25 + 32.
°F = 45 + 32.
°F = 77.
