Of 80 people attending a dance 28 dance with their hands touching the floor. If four people at the dance are selected at random, determine the probability that each of the 4 dance with their hands touching the floor.
`PLEASE HURRY ITS A QUIZ
Answers
Answer: The probability is 0.013
Step-by-step explanation:
Out of 80 people, 28 of them dance with the hands touching the ground.
Then, the probability of selecting at random someone that dances with the hands touching the floor is equal to the number of persons that dance in that way, divided by the total number of persons.
For the first selection, this is p1 = 28/80
now, the probability in the second selection will be 27/79, because we have selected 1 out of the 28 (and also 1 out of the 80)
for the third and the fourth we have:
p3 = 26/78
p4 = 25/77
Then the probability of the fourth events is equal to the product of the four probabilities:
P = (28/80)*(27/79)/(26/78)/(25/77) = 0.013
Answer:
The probability that each of the 4 dance with their hands touching the floor is 0.0129.
Step-by-step explanation:
There are a total of 80 people and out of them, 28 dance with their hands touching the floor. The probability of selecting a person who has their hands touching the floor while dancing can be computed as 28/80.
We are asked to computed the probability that four people are selected at random and all four of them dance with their hands touching the floor. The probability for selecting the first person is 28/80. For the second person, the total no. of people are now 79 and the people who can dance with their hands touching the floor are 27. So, the probability is 27/79. Similarly, for the third person, the probability is 26/78 and for the fourth person, the probability is 25/77.
So, the probability that all four people selected dance with their hands touching the floor is:
28/80 * 27/79 * 26/78 * 25/77 = 0.0129

Answers
Answer:
15. 50 kg
16a. 5 kg
16b. 3.75 kg
Step-by-step explanation:
The formula relating force, mass, and acceleration can be solved for mass. This formula will apply to both problems. We'll use m for both "mass" and "meters". We presume you can avoid getting mixed up by understanding that meters is used in the context of acceleration: m/s².
F = ma
m = F/a . . . . . divide by a
__
15. m = (250 N)/(5 m/s²) = 50 kg
__
16a. m = (15 N)/(3 m/s²) = 5 kg
16b. m = (15 N)/(4 m/s²) = 3.75 kg
_____
Comment on units
Especially for physics problems, I like to keep the units with the numbers. It is helpful to remember that Newtons are equivalent to kg·m/s². So, dividing Newtons by acceleration in m/s² will give mass in kg. Since you're familiar with F=ma, it's not too hard to remember that the units of force (N) are the product of the units of mass (kg) and acceleration (m/s²).

There are 6 faces on a cube. Each face is equal to the area of one square.
Area of one square = 2.5 x 2.5 = 6.25 units^2
Surface area = 6.25 x 6 = 37.5 units^2
Hope this helps!! :)
Answer:
37.5
Step-by-step explanation:
Since it is a cube, all edges are 2.5. To find one side, you do 2.5x2.5. That gives you 6.25. And you have 6 sides. So 6.25x6 = 37.5.
The measure of angle M is_degrees.
Answers
Answer:
m=37
Step-by-step explanation:
The 2 angles are complementary, or add to 90 degrees. Wee know this because of the little square in the corner that indicates a right angle, which is equal to 90 degrees.
m+53=90
Solve for m by getting m by itself. To do this, subtract 53 from both sides to "reverse" the addition being done to m.
m+53-53=90-53
The 53s on the left cancel, and we are left with:
m=37
Answer:
M = 37°
Step-by-step explanation:
M + 53° = 90°
M = 90° - 53°
M = 37°

Round your answer to the nearest tenth and do NOT include units.
Answers
Answer: 151
Step-by-step explanation:
In this situation we have two cones, the big cone with volume [tex]V_{big}[/tex] and the small cone with volume [tex]V_{small}[/tex].
Now, if we want to know the total volume [tex]V_{T}[/tex] we have to substract [tex]V_{small}[/tex] from [tex]V_{big}[/tex], but first we have to calculate each volume:
For the big cone:
[tex]V_{big}=\frac{\pi R^{2} H}{3}[/tex]
Where:
[tex]R=\frac{Diameter}{2}=\frac{8 in}{2}=4 in[/tex]
[tex]H=9 in[/tex]
Then:
[tex]V_{big}=\frac{\pi (4 in)^{2} 9 in}{3}[/tex]
[tex]V_{big}=150.79 in^{3}[/tex] Volume of big cone
For the small cone:
[tex]V_{small}=\frac{\pi r^{2} h}{3}[/tex]
Where:
[tex]r=\frac{diameter}{2}=\frac{1 in}{2}=0.5 in[/tex]
[tex]h=1 in[/tex]
Then:
[tex]V_{small}=\frac{\pi (0.5 in)^{2} 1 in}{3}[/tex]
[tex]V_{small}=0.261 in^{3}[/tex] Volume of small cone
Calculating the total volume:
[tex]V_{T}=V_{big}-V_{small}[/tex]
[tex]V_{T}=150.79 in^{3}-0.261 in^{3}[/tex]
Finally:
[tex]V_{T}=150.52 in^{3} \approx 151 in^{3}[/tex]

In a lab, a substance was heated by 6 °C each hour for 60 hours. What was the total change
in temperature?
Answers
Final answer:
The total change in temperature when a substance is consistently heated by 6 °C each hour for 60 hours is 360 °C, calculated by multiplying the hourly temperature increase by the number of hours.
Explanation:
To calculate the total change in temperature when a substance is heated by a consistent amount over a period of time, you simply multiply the rate of temperature change per hour by the total number of hours. In this case, the substance was heated by 6 °C each hour for 60 hours. So, the calculation will be 6 °C/hour * 60 hours.
The total change in temperature is therefore 6 °C/hour * 60 hours = 360 °C. This calculation shows the cumulative effect of consistent heating over a certain period.

The nth term of a sequence is n-4
a) Work out the first three terms of the sequence.
b) Work out the tenth term of the sequence.
Answers
Answer:
Step-by-step explanation:
nth term = n - 4
A) 1st term = 1 - 4 = -3
2nd term = 2 - 4 = -2
3rd term = 3 - 4 = -1
First three terms are: -3, -2, -1
b) tenth term = 10 - 4 = 6
a) The first three terms of the sequence are -3, -2, and -1.
b) The tenth term of the sequence is 6.
a) To find the first three terms of the sequence with the nth term given as n - 4, we can substitute the values of n from 1 to 3 into the formula:For n = 1:nth term = n - 4 = 1 - 4 = -3For n = 2:nth term = n - 4 = 2 - 4 = -2For n = 3:nth term = n - 4 = 3 - 4 = -1So, the first three terms of the sequence are: -3, -2, -1.b) To find the tenth term of the sequence, we can again use the formula with n = 10:nth term = n - 4 = 10 - 4 = 6So, the tenth term of the sequence is 6.For more questions on sequence -

Complete the sentence below with less than,
greater than or equal to.
The sum of the first 100 even natural numbers is
the sum of the first 101 odd
natural numbers.
Answers
Answer: The Answer is "less than"
Step-by-step explanation:
To find the sum of a series, you find the difference between the first and last term, multiply that by the number of terms, then divide by 2.
For the even numbers, 2 is the first term and 200 is the 100th term (because 2+(100-1)2 is equal to 200). So, (100(2+202)/2 = 10100.
For the odd numbers, 1 is the first term and 201 is the 101th term (because 1+(101-1)2 is equal to 201). So, (101(1+202))/2 = 10251.5.
10100<10251.5 so the sum of the first 100 even numbers is less than the sum of the first odd 101 numbers.
The sum of the first 100 even natural numbers is smaller than the sum of the first 101 odd natural numbers.
What is an even number?A number that is divisible by two into two equal whole numbers is called an even number. Even numbers are those that end in 0, 2, 4, 6, and 8.
The problem can be solved using the arithmetic sequence. The sum of the first 100 even numbers will be,
[tex]\text{Sum of first 100 even numbers} = \dfrac{100}{2} \times [2(2) +(100-1)2]=10,100[/tex]
The sum of the first 101 odd numbers will be,
[tex]\text{Sum of first 101 odd numbers} = \dfrac{101}{2} \times [2(1) +(101-1)2]=10,201[/tex]
Hence, the sum of the first 100 even natural numbers is smaller than the sum of the first 101 odd natural numbers.

The image of point L (-4,0) after a dilation with a scale factor of 2 from the center (0,0) is L' (-8,0).
Explanation:
To find the image of the point L (-4,0) after a dilation with a scale factor of 2 from the center (0,0), you multiply the coordinates of the point by the scale factor. Therefore, the coordinates of point L after dilation (L') would be (-4 × 2, 0 × 2) = (-8, 0).
The image of point L after the dilation is L' with coordinates (-8, 0).
