Step-by-step explanation:
Step 1: Determine the value of x by using [tex]x=tan^{-1}(\frac{\sqrt{3} }{\sqrt{2}} )[/tex]
[tex]x=tan^{-1}(\frac{\sqrt{3}}{\sqrt{2} })=50.7685 degrees[/tex]
Step 2: Substitute x=50.7685 degrees into the original equation
[tex]2cos^{4}(x)-sin(x)=2cos^{4} (50.7685)-sin(50.7685)=0.320-0.7746=-0.4546[/tex]

There are 4 red balls and 6 black balls in a bag. Draw consecutively 3 balls with replacement. Find the probability when the first two balls drawn are black and the third ball drawn is red.
Answers
Answer:
[tex]\frac{1}{3} *\frac{1}{2} =\frac{1}{6}[/tex]
Step-by-step explanation:
So the first two balls are black, so the way to change the path is to take two out of six black balls over two out of ten balls, which is 1/3.
If the last one is red then the probability is that if you take one of the four red balls and you take one of the eight balls, you get 1/2.
So the total probability is 1/3 times 1/2 is 1/6.

In a class of 29 students, 10 are female and 20 have an A in the class. There are 2 students who are male and do not have an A in the class. What is the probability that a female student does not have an A?Answer this
Answers
Answer:
The probability would be 3 out of the 10 girls
Step-by-step explanation:
The probability that a female student does not have an A on the test is 7/29.
What is the probability that a female student does not have an A?
Probability is mathematical operation that is used to determine how likely a stated event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that a female student does not have an A = number of females that do not have an A / total number of females
(29 - 20 - 2 )/ 29 = 7/29

so first of all we need to get rid of the time that isn't spent in class, because the question is asking about the time spent in class. so we would add 30+42 giving us 72 minutes, or 1 hour and 12 minutes. Now we can subtract 1 hour and 12 minutes from 7 hours to find the total time spent in class. Which would give us 5 hours and 48 minutes. (reminder; 60 minutes in 1 hour)
now that we have the total time spent in class, all that is left is division. The equation would be easier to solve when the hours are converted into minutes. 5 hours and 48 minutes equal, 348 minutes. Now we would divide 348 by 6 as there are 6 classes that take 348 minutes in all, and we wanna find how long 1 class takes. 348 divided by 6 would then give us 58. so each class takes 58 minutes.

Use the substitution method to solve the system.
2x + 8y = 4
x = -4y - 2
Answers
Answer:
no solution
Step-by-step explanation:
2x + 8y = 4
x = -4y - 2
Divide both sides of the first equation by 2.
x + 4y = 2
x = -4y - 2
Substitute -4y - 2 for x in the first equation.
-4y - 2 + 4y = 2
0 - 2 = 2
0 = 4
Since after doing legal steps, we get a false statement, 0 = 4, that means there is no solution.

If there were 310 million people in the United States, what was the daily consumption rate in barrels per person in the United States? This is also called "barrels per capita." Round to the nearest hundredth of a barrel.
Answers
The daily consumption rate in the United States will be 10 barrels per person.
Your question is incomplete as you didn't provide the total barrels, therefore, an overview of the answer will be given. In their case, let's assume that the total barrels is given as 3.1 billion.
Therefore, the barrels per person will be:
= Total barrels / Population
= 3.1 billion / 310 million
= 10 barrels per person.
In conclusion, the correct option is 10 barrels per person.

Answers
Answer:
7.76 minutes
Step-by-step explanation:
The +51 is regardless (being the y intercept) so it does not affect our answer. If the employee has to drive one mile (x=1) it will take 7.76 + 51 min to get there. If they have to drive 0 miles (x=0) it will only take 51 min. This is a difference of 7.76. You really just need to take the slope (I just used this example to make it make more sense) as x is the number of miles the employee has to drive, and therefore that times 7.76 would be how much longer it would take to drive to work.
