Gabriela bought 48 tickets in order to win the $1000 grand prize for the raffle organized by the Student Council. If there are
432 tickets sold for the raffle, what is the probability that Gabriela will not win the grand prize?
Answers
Answer:
[tex]\frac{8}{9}[/tex]
Step-by-step explanation:
Since there are 432 tickets total and Gabriela bought 48, the chances of Gabriela not winning the grand prize is equal to the chance of any of the tickets she did not buy getting drawn. If she bought 48, then she did not buy 432-48=384 tickets. The chances of any of these being drawn is:
[tex]\frac{384}{432}=\boxed{\frac{8}{9}}[/tex]

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?
Answers
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

What is Recursive functions?Recursive functions are ways of expressing sequence using functions. Recursive Function is a function that repeats or uses its own previous term to calculate subsequent terms and thus forms a sequence of terms.
here, we have,
given that,
Given the following recursive functions
a₁=7 and;
aₙ = -3aₙ₋₁
For the second term;
a₂ = -3a₁
a₂ = -3(7)
a₂ = -21
For the third term a₃
a₃ = -3a₂
a₃ = -3(-21)
a₃ = 63
For the fourth term
a₄ = 3a₃
a₄ = 3(63)
a₄ = 189
For the fifth term
a₅ = 3a₄
a₅ = 3(189)
a₅ = 567
Hence the fifth term of the recursive sequence is 567.

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

the area of a square whose sides have length x cm is increasing at the rate of 12cm²/s. how fast is the length of a side increasing when the area is 81cm²
Answers
Answer:
0.67 cm/s
Step-by-step explanation:
The area of a square is given by :
[tex]A=x^2[/tex] ....(1)
Where
x is the side of a square
[tex]\dfrac{dA}{dt}=12\ cm^2/s[/tex]
Differentiating equation (1) wrt t.
[tex]\dfrac{dA}{dt}=2x\times \dfrac{dx}{dt}[/tex]
When A = 81cm², the side of the square, x = 9 cm
Put all the values,
[tex]12=2\times 9\times \dfrac{dx}{dt}\\\\\dfrac{dx}{dt}=\dfrac{2}{3}\\\\\dfrac{dx}{dt}=0.67\ cm/s[/tex]
So, the length of the side of a square is changing at the rate of 0.67 cm/s.

Slope
Y intercept
Answers
Answer:
Slope = -7/8
Y-intercept = (0, 1)
Step-by-step explanation:
Answer:
[tex]slope = - \frac{7}{8} [/tex]
y- intercept= 1
Step-by-step explanation:
Rearrange the equation such that it is in the form of y=mx+c. This form is known as the slope-intercept form, and m is the gradient while c is the y-intercept.
7x +8y= 8
8y= -7x +8
Divide by 8 on both sides:
[tex]y = - \frac{7}{8} x + 1[/tex]
Thus, the slope is [tex] - \frac{7}{8} [/tex] and the y-intercept is 1.
Another way to find the y-intercept is to substitute x= 0 into the equation since the y-intercept occurs at x= 0.
7x +8y= 8
When x= 0,
7(0) +8y= 8
8y= 8
y= 8 ÷8
y= 1
Thus, the y-intercept occurs at y= 1 or the coordinate (0, 1).
Note: slope and gradient have the same meaning and can be used interchangeably
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.
Answers
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.

Using the picture above Find the measure of arc EF
Answers
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].

Answers
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
