Hakeem owns seven less than 3/5
the number of DVDs that Manuel owns. Hakeem owns 20 DVDs. How many DVDs does Manuel own? Show your work.
Answer: 45 DVDs
Step-by-step explanation:
Assume that the number of DVDs owned by Manuel is x.
In comparison to Manuel therefore, the DVDs owned by Hakeem can be expressed as:
= 3/5 * x - 7
We know that Hakeem owns 20 DVDs so we can use this number to solve for x:
20 = 3/5x - 7
3/5x = 20 + 7
3/5x = 27
x = 27 ÷ 3/5
x = 27 * 5/3
x = 45 DVDs
Using the picture above Find the measure of arc EF
Given:
Measure of arc CG is 125 degrees.
The measure of angle CDG is 85 degrees.
To find:
The measure of arc EF.
Solution:
Intersecting chords theorem: If two chords intersect each other inside the circle, then the measure of angle on the intersection is half of the sum of intercepted arcs.
Using the intersecting chords theorem, we get
[tex]m\angle CDG=\dfrac{1}{2}(m(arcCG)+m(arcEF))[/tex]
Let x degrees be the measure of arc EF.
Substituting the given values, we get
[tex]85^\circ=\dfrac{1}{2}(125^\circ+x)[/tex]
[tex]2\times 85^\circ=125^\circ+x[/tex]
[tex]170^\circ -125^\circ=x[/tex]
[tex]45^\circ=x[/tex]
Therefore, the measure of arc EF is [tex]45^\circ[/tex].

Answer: Subtracted 9.
Step-by-step explanation: To solve equations such as these, you always do the opposite than whatever the term is. For example, in your equation, "13" and "x" are MULTIPLIED together, which is why it's divided. The 9 is subtracted, which means it would need to be added to the other side.
Always remember that these equations are like scales- each side needs to be equal.

A national organization has been working with utilities throughout the nation to find sites for large wind machines that generate electricity. Wind speeds must average more than 20 miles per hour (mph) for a site to be acceptable. Recently, the organization conducted wind speed tests at a particular site. Based on a sample of n = 43 wind speed recordings (taken at random intervals), the wind speed at the site averaged x = 25.8 mph, with a standard deviation of s = 4.2 mph. To determine whether the site meets the organization's requirements, consider the test, H0: µ = 25 vs. Ha: µ > 25, where µ is the true mean wind speed at the site and alpha = .01. Suppose the value of the test statistic were computed to be 1.25. State the conclusion.
A) At alpha = .01, there is sufficient evidence to conclude the true mean wind speed at the site exceeds 25 mph.
B) At alpha΅= .01, there is insufficient evidence to conclude the true mean wind speed at the site exceeds 25 mph.
C) We are 99% confident that the site meets the organization's requirements.
D) We are 99% confident that the site does not meet the organization's requirements.
Answer:
B) At alpha = 0.01, there is insufficient evidence to conclude the true mean wind speed at the site exceeds 25 mph.
Step-by-step explanation:
P-value of the test:
The p-value of the test is the probability of finding a sample mean above 25.
We are using the t-distribution, with test statistic t = 1.25 and 43 - 1 = 42 degrees of freedom. This probability is a right-tailed test.
With the help of a calculator, this p-value is of 0.1091.
Since the p-value of the test is 0.1091 > 0.01, at [tex]\alpha = 0.01[/tex] there is insufficient evidence to conclude the true mean wind speed at the site exceeds 25 mph, and the correct answer is given by option B.

Answer:
The final answer is 78 inches, though I would recommend for you to read through the steps of how this is achieved.
Step-by-step explanation:
To start, to grasp the corresponding sides deal, think of it as saying Quad 1234 is equal to Quad ABCD. Now, it is fairly easy to make up the sides between the two shapes. With this, the following is true:
Side 12 ≅ Side AB
Side 23 ≅ Side BC
Side 34 ≅ Side CD
With the end, it loops back around to meet back at the first edge of the shape again, if you're looking for a side length.
Side 41 ≅ Side DA
Now, with the real stuff. We're greeted with the Quads DEFG and KLMN, and asked to find FG. Looking at it, FG would be using the 3rd and 4th letters of the set of quad edges. Comparing this to the other quad shape, the 3rd and 4th letters are MN. Therefore, lets use this.
Next, set these equal to each other. FG is 5y+3 and MN is 7y-27
5y+3 = 7y-27
5y = 7y-30
-2y = -30
2y = 30
y = 15
y equals 15.
Lastly, plug this into the equation for FG to get the final answer.
5(15)+3
75+3
78 inches
After the warm-up the participant performs the WAnT. You don't have equipment to automatically track power output, therefore, you count revolutions for each 5 second period of the test. The results are as follows:
Time(sec) 5sec_rpm cumulative
0-5 10 10
5-10 7 17
10-15 9 26
15-20 7 33
20-25 7 40
25-30 6 46
The power output can now be computed for each 5 second period using the following equation:
kg of resistance x number of revolutions x 11.765= power (watts)
Required:
What is the power output for each 5 second period?
Answer: Missing detail ( weight of resistance = 6.69 Kg )
answer :
787.0785 watts 550.95 watts708.37 watts 550.95 watts 550.95 watts 472.25 wattsStep-by-step explanation:
Applying the equation for computing the power output
= Kg of resistance * number of revolutions * 11.765 ------- ( 1 )
Calculate the power output for each 5 second period
weight ( Kg of resistance ) = 6.69 Kg
Equation 1 becomes :
6.69 * number of revolutions * 11.765 ---- ( 2 )
Next :Apply equation (2) to every 5 seconds interval as represented in the table
For Time 0 - 5
Number of revolutions ( rpm ) = 10
power output = 6.69 * 10 * 11.765 = 787.0785 watts
cumulative rpm = 10 + 0
Cumulative Power = power output + previous power output = 787. 0785watt
For Time ( 5 - 10 )
Number of revolutions ( rpm ) = 7
Power output = 6.69 * 7 * 11.765 = 550.95 watts
Cumulative rpm = rpm + previous rpm = 7 + 10 = 17
Cumulative power = power output + previous power output
= 550.95 + 787.0785 = 1338.0285 watts
Power output for ( 10 - 15 ) = 6.69 * 9 * 11.765 = 708.37 watts
Power output for ( 15 - 20 ) = 6.69 * 7 * 11.765 = 550.95 watts
Power output for ( 20 - 25 ) = 6.69 * 7 * 11.765 = 550.95 watts
Power output for ( 25 - 30 ) = 6.69 * 6 * 11.765 = 472.25 watts
Marcia is traveling with her family in the car. If they traveled 240 miles in 4 hours, at what rate, or speed were they traveling? Use the formula d ÷ t, where d represents the distance and t represents the time.
80 miles per hour
236 miles per hour
40 miles per hour
60 miles per hour
Answer:
60 miles per hour
Step-by-step explanation:
240/4 = 60 miles per hour
Answer:
60 miles per hour
Step-by-step explanation:
In order to find the rate at which Marcia's family's' car is travelling, you would simply divide the total miles, which would be 240 or "d," by the time, which would be 4 hours or "t."
[tex]\frac{240}{4}[/tex] = 60So, Marcia's family's car is travelling at 60 miles per hour.

Answer:
2
Step-by-step explanation:
Hello !
In order to add fractions...
*You must have a common denominator (remember the top is the numerator and the bottom is the denominator)
So...
1 1/2 + 1/2
Although both have a 2 at the bottom, you can't add these because 1 1/2 is a mixed number and 1/2 isn't. To add them, you have to turn 1 1/2 into an improper fraction. You do this by multiplying the denominator by the whole number and then adding that to the numerator.
So 1 1/2 is the same thing as 3/2.
Now, you can add straight across.
3/2 + 1/2 = 4/2
4/2 = 2
Your answer is : 2
I hope this helps, please let me know if you're confused or have any more questions and I'll be happy to help.

A and B are two events. Let P(A) = 0.3, P(B) = 0.9, and P(Aand B) = 0.24. Which statement is true?
Answer:
blue one (c), not independent because P(A|B) ≠ P(A)
Step-by-step explanation:
Two events are independent of each other if you can mulitply them to get their intersection
To find the conditonal probability of two independent events you can use the following idea/formula
P(A|B)= (P(A)*P(B))/P(B) which simplifies to P(A) (so the probability of A given B when A and B are independent of each other is just the probability of A)
Now with the numbers we're given let's find P(A|B)
.24/.9= .26666666666667
Because this is not equal to .3 (or P(A)) the answer must be the blue one
