Answer:
C. $875
Step-by-step explanation:
The rule of housing is the rule of thumb of not using more than 25% of your gross income. This means that the households supposed limited expenses on housing would be a maximum of 25% only.
So to find the monthly housing budget of Bryson, we simply take his annual salary and multiply it by 25% or 0.25 and then divide the product by 12.
Monthly Housing Budget = ($42,000 * 0.25)/12
Monthly Housing Budget = 10500/12
Monthly Housing Budget = $875

45 POINTS PLEASE HELP ME!!!! You roll two standard number cubes. What is the probability that the sum is odd, given than one of the number cubes shows a 4?
Answer:
6/11
Step-by-step explanation:
We are not told which number cube shows a 4; it can be the first one or the second one.
If the first number cube is a 4, this gives us the options of:
4 and 1; 4 and 2; 4 and 3; 4 and 4; 4 and 5; 4 and 6.
However if the second number cube is a 4, this gives us
1 and 4; 2 and 4; 3 and 4; 4 and 4; 5 and 4; 6 and 4.
We cannot count "4 and 4" twice; this leaves us with 11 total possibilities.
Out of these 11, only the sum of 4 and an odd number will be odd:
1 and 4; 3 and 4; 5 and 4; 4 and 1; 4 and 3; 4 and 5.
There are 6 ways to have an odd sum out of 11 total possibilities; this gives us a probability of 6/11.
The losing team in a baseball game scored 2 runs. Which inequality represents the number of runs, r , that the winning team could have scored? A. R?2 B. R>2 C. R<2 D. R=2
B. R>2 because to win the game they must have had more runs than the losing team
Final answer:
The inequality that represents the number of runs the winning baseball team could have scored is r > 2, since the winning team must score more than the losing team, which scored 2 runs.
Explanation:
The student is asking for the inequality that represents the number of runs, r, that the winning team could have scored in a baseball game, given that the losing team scored 2 runs. The condition to win a game is that the winning team must score more runs than the losing team. Therefore, if the losing team scored 2 runs, the inequality that represents the number of runs the winning team scored is r > 2. This is because the winning team must have scored more than 2 runs to win.
If P(A)=0.35, then the probability of the complement of A is
0.55
-0.35
0.35
0.65
Answer:
P(A') = 0.65
Step-by-step explanation:
We are given that the probability P(A) = 0.35 and we are to determine the probability of the complement of A.
According to the Complement Rule of any probability, the sum of the probabilities of an event and its complement must be equal to 1.
So for for the event A,
P(A) + P(A') = 1
0.35 + P(A') = 1
P(A') = 1 - 0.35
P(A') = 0.65
The probability of the complement of A is 0.65
How to determine the probability of the complement of AThe probability of A is given as:
P(A) = 0.35
To calculate the probability of the complement of A, we make use of the following complement formula
P'(A) = 1 - P(A)
So, we have:
P'(A) = 1 - 0.35
Evaluate
P'(A) = 0.65
Hence, the probability of the complement of A is 0.65

Solve a triangle with a=25, b=30, and C= 160°
(picture provided)
Answer:
Option d.
Step-by-step explanation:
For this problem we have 2 sides of a triangle (a and b) and the angle between them C = 160 °.
We have a triangle of type SAS.
We have:
a=25
b=30
C= 160°
Then we use the law of cosine.
[tex]c = \sqrt{a^2 +b^2 - 2abcos(C)[/tex]
Now we substitute the values in the formula to find c
[tex]c = \sqrt{25^2 +30^2 - 2(25)(30)cos(160\°)}\\\\c = 54.2[/tex]
Now we use the cosine theorem to find B. (You can also use the sine)
[tex]b = \sqrt{a^2 +c^2 - 2accos(B)}\\\\b^ 2 = a^2 +c^2 - 2accos(B)\\\\b^ 2 -a^2 -c^2 =- 2accos(B)\\\\\frac{a^2 +c^2 -b^2}{2ac} =cos(B)\\\\B = arcos(\frac{a^2 +c^2 -b^2}{2ac})\\\\B = arcos(\frac{25^2 +54.2^2 -30^2}{2(25)(54.2)})\\\\B = 10.9\°[/tex]

Susan Sound predicts that students will learn most effectively with a constant background sound, as opposed to an unpredictable sound or no sound at all. She randomly divides twenty-four students into three groups of eight. All students study a passage of text for 30 minutes. Those in group 1 study with background sound at a constant volume in the background. Those in group 2 study with noise that changes volume periodically. Those in group 3 study with no sound at all. After studying, all students take a 10-point multiple choice test over the material. Their scores follow: Table Constant sound Random Sound No Sound 7 5 2 4 5 4 6 3 7 8 4 1 6 4 2 6 7 1 2 2 5 9 2 5 1. State the type of statistical test that you will use to conduct your hypothesis test.
Answer:
An ANOVA test
Step-by-step explanation:
You will use the ANOVA test, which is a test that compares the means of more than 2 samples. Since the teacher used 3 test groups, she would have to use this test if she wanted to do a hypothesis test to determine if the means are equal.
*This test only tells us if the means are equal, it won't say which is greater than the other. You would have to do 3 individual hypothesis tests comparing 2 means at a time in order to determine that.
An ANOVA (Analysis of Variance) is the appropriate statistical test to use when comparing the test scores of students studying under different sound conditions (constant sound, random sound, and no sound).
The type of statistical test to use for conducting a hypothesis test in this scenario would likely be an ANOVA (Analysis of Variance), which is specifically designed to compare the means of three or more groups. Since we have three independent groups of students (constant sound, random sound, and no sound) and we want to test if there is a significant difference in the test scores that could be attributed to the study condition, ANOVA is the appropriate choice of test.
The information provided about the music and sound conditions suggests that the volume of any background music should be low enough to not disrupt conversation and that it may serve as an auditory memory cue if used consistently. Additionally, the studies mentioned indicate various effects of background music on task performance among students, be it learning a passage, recalling information, or completing reading comprehension tasks. These factors would be considered when interpreting the results of the ANOVA.

Answer:
35 7/8.
Step-by-step explanation:
The total length of the wood before any cutting was done = 4 * the mean
= 4* 36 5/8 = 4* 293/8
= 146 1/2 feet.
So the length of the fourth piece = 146 1/2 - (36 3/4 + 36 3/8 + 37 1/2)
= 146 1/2 - 110 5/8
= 36 + 1/2 - 5/8
= 35 7/8 answer.
Turn the mean into an improper fraction.
36 5/8 = 293/8
Multiply the mean by four.
293/8 * 4/1 = 1172/8 or 146 1/2
Add all the sides together.
36 3/4 + 36 + 3/8 + 37 1/2 = 110 5/8 or 885/8
Subtract.
1172/8 - 885/8 = 287/8 or 35 7/8

Describe, in your own words, the identity sin^2(x) + cos^2(x) = 1.
Look at the attached figure. We define the unit circle as a circle with center [tex]A[/tex] in the origin (0,0) and radius 1.
Then, we consider a point P on the circumference. We call [tex]\alpha[/tex] the angle between the positive half of the x axis and the radius AP.
We define

The National Football League (NFL) polls fans to develop a rating for each football game. Each game is rated on a scale from 0 (forgettable) to 100 (memorable). The fan ratings for a random sample of 12 games follow. 57 61 87 74 72 73 19 56 81 79 83 75 a. Develop a point estimate of mean fan rating for the population of NFL games (to 2 decimals). b. Develop a point estimate of the standard deviation for the population of NFL games (to 4 decimals).
The point estimates for the mean and standard deviation of the given data is respectively; 68 and 17.6
What is point Estimate?A) To find the point estimate of the mean, we add all up all the data and divide by the number of values.
Thus;
∑x = 57 + 61 + 86 + 87 + 72 + 73 + 19 + 56 + 81 + 79 + 83 + 75 = 816
n = 12 numbers
Thus;
mean = ∑x/n = 816/12
Mean = 68
B) To find the estimate of the standard deviation, we would get it from the formula;
s = √[(n*(∑x²) - (∑x)²)/n(n - 1)]
∑x² = 572 + 612 + 862 + ... + 742 = 59,010
s = √[ (12*(59,010) - (816)²)/(12)(11)]
s = 17.6

What are the advantages and disadvantages of technological versus old-school methods for determining position at sea.
Answer:
A mere 15 years back, navigators would have scoffed at the idea of Paperless Navigation on big ocean going ships. After all, since centuries, navigational paper charts had been the heart and soul of ship navigation. Imagining that a day would come where we’d no longer have them onboard was nothing short of blasphemy.
Step-by-step explanation:
The advantages of technology versus old-school methods for determining the position at sea include ease of navigation and safety.
What is the ECDIS?The ECDIS is the abbreviated form Electronic Chart Display and Information System. It is a modern technology used for navigation through waters.
The advantages and disadvantages of technology versus old-school methods for determining the position at sea are as follows:With ECDIS as the dominant source of sailing, the Navigating Officer can plan and summarise the transition much more speedily than on Paper Charts.
This is the background that will sound an alarm if the ship is inside the limit stated.

For the circle with equation (x - 2)² + (y+3)² = 9 , answer each question.
(a) What are the coordinates of the center?
(b) What are the radius and diameter of the circle?
(c) Graph the circle.
Answer:
The center is (2 ,-3)
The radius is 3
The diameter is twice the radius = 2(3) = 6
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2 + (y-k)^2 =r^2
where (h,k) is the center and r is the radius
(x - 2)² + (y+3)² = 9
(x - 2)² + (y- -3)² = 3^2
The center is (2 ,-3)
The radius is 3
The diameter is twice the radius = 2(3) = 6
The center of the circle is at (2, -3), the radius is 3 units, and the diameter is 6 units. To graph the circle, plot the center point (2, -3) and draw a circle with a radius of 3 units around it.
Explanation:(a) The coordinates of the center of the circle are (2, -3). The equation of the circle is in the form (x - h)² + (y - k)² = r², where (h, k) are the coordinates of the center and r is the radius. In this case, (h, k) = (2, -3).
(b) The radius of the circle is 3 units. The diameter is twice the radius, so the diameter of the circle is 6 units.
(c) To graph the circle, plot the center point (2, -3) and draw a circle with a radius of 3 units around it.

This implies that;
[tex]y=5(-2)-1[/tex]
[tex]y=-10-1[/tex]
[tex]y=-11[/tex]
The solution is (-2,-11)
Answer:
(-2, -11)
Step-by-step explanation:
We are given the following two equations:
[tex]-5x + y = -1[/tex] --- (1)
[tex]y - 4x = -3[/tex] --- (2)
From equation (2):
[tex]y=4x-3[/tex]
Substituting this value of y in equation (1) to get:
[tex]-5x + y = -1[/tex]
[tex]-5x + (4x-3) = -1[/tex]
[tex]-5x+4x=-1+3[/tex]
[tex]x=-2[/tex]
Now substituting the value of x in equation (2) to get:
[tex]y - 4(-2) = -3[/tex]
[tex]y+8=-3[/tex]
[tex]y=-8-3[/tex]
[tex]y=-11[/tex]

The nth term of the sequence is
[tex]a_n=3(3)^{n-1}[/tex]
To get the first term, substitute n=1,
[tex]a_1=3(3)^{1-1}=3[/tex]
To get the second term, substitute n=2,
[tex]a_2=3(3)^{2-1}=9[/tex]
To get the third term, substitute n=3,
[tex]a_3=3(3)^{3-1}=27[/tex]
The sum of the first three terms is
[tex]S_3=3+9+27=39[/tex]
We could also use the formula
[tex]S_n=\frac{a_1(r^n-1)}{r-1}[/tex] to get the same result.
Answer:
The correct answer is last option 39
Step-by-step explanation:
It is given that,
aₙ = 3(3)ⁿ⁻¹
To find a₁
a₁ = 3(3)¹⁻¹ = 3(3)°
= 3 * 1 = 3
To find a₂
a₂ = 3(3)²⁻¹ = 3(3)¹
= 3 * 3 = 9
To find a₃
a₃ = 3(3)³⁻¹ = 3(3)²
= 3 * 9 = 27
To find the value of S₃
S₃ = a₁ + a₂ + a₃
= 3 + 9 + 27 = 39
Therefore the correct answer is last option 39

Which is the equation in the slope-intercept form for the line that passed through (2, 8) And it is perpendicular to 4x + 2y= 6?
Answer: [tex]y=\frac{1}{2}x+7[/tex]
Step-by-step explanation:
The slope-intercept form of the equation of the line is the following:
[tex]y=mx+b[/tex]
Where m is the slope and b the y-intercept.
By definition, when two lines are perpendicular, their slopes are opposite reciprocals.
Then, to find the slope of the equation of the line given, you can solve for y:
[tex]4x+2y=6\\2y=-4x+6\\\\y=-2x+3[/tex]
As you can see, the slope of this line is -2.Then, the slope of the line that is perpendicular to it, must be:
[tex]m=\frac{1}{2}[/tex]
Substitute the slope and the point given, into the equation and solve for b:
[tex]8=\frac{1}{2}(2)+b\\8=1+b\\b=7[/tex]
Therefore, the equation of this line is:
[tex]y=\frac{1}{2}x+7[/tex]

Final answer:
The length of the third side of the triangle is approximately 11.66 feet.
Explanation:
To find the length of the third side of a triangle, we can use the Pythagorean theorem. According to the theorem, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the lengths of the two sides given are 6 feet and 10 feet. So, we can calculate the length of the third side as follows:
a² + b² = c²
6² + 10² = c²
36 + 100 = c²
136 = c²
c = √136
c ≈ 11.66 feet

Answer:
Correct choice is D). -4.
Step-by-step explanation:
Given the following relation is a function where the relation is :
{(6,3),(-4,1),(8,-5),(x,1)}
Now we need to decide about which of the following cannot be a value for x.
Where given choices are:
A). 3
B). 1
C). -5
D). -4
E). 4
We know that a relation is called function if doesn't contains repeated values in domain or doesn't have repeated x-values.
In given relation, {(6,3),(-4,1),(8,-5),(x,1)}, we see that x-values are 6, -4 and 8.
So to prevent repetition, x can't be any of 6, -4 and 8.
Hence correct choice is D). -4.
