Out of 60 applicants to a university, 40 are from the East. If 20 applicants are to beselected at random, find the probability that:
a. 10 are from East.
b. Not more than 2 are from East.
Answer:
a. 40С10 * 20С10 / 60С20
b. 1 + (40)(20) + (40C2)(20C2) / 60С20
Step-by-step explanation:
Total number of application = 60
Total number of application from east = 40
Total number of application remaining = 20
Number of ways of selecting 20 applicant = 60C20 (Sample space)
a. Probability of 10 are from East.
= (10 from east) * (10 from remaining)
= 40С10 * 20С10 / 60С20
b. Probability of Not more than 2 are from East.
= P(x≤2)
= P(x=0) + P(X=1) + P(X=2)
= [40С0 * 20С20 / 60С20] + [40С1 * 20С19 / 60С20] + [40С2 * 20С18 / 60С20]
= 1 + (40)(20) + (40C2)(20C2) / 60С20
A 180 pound person is hanging onto a 15-foot rope. Assuming the rope is uniform and that it weighs 2 pound per foot, set up (but do not evaluate) the integral that would calculate the work required to pull the person up 15 feet. Explain what of the values in your expression represent by labeling each.
Answer:
The answer is "g= 32 FPS"
Step-by-step explanation:
Given value:
[tex]mass = 180\\\\length= 15 \\\\\lambda = \frac{ mass}{ length} = 2 \ \text{pound per foot} \\\\\bold{Formula}\\\\ \to w \int_{a}^{b} F \cdot d \ dx = \int_{0}^{15} (2x+180) \ g \ dx[/tex]
by solving the value we get the value of g that is equal to 32.

Describe two differences in the atomic structure of nitinol and the atomic structure of either nickel or titanium that result in different physical properties of the elements used to make nitinol. CAN ANYONE HELP, PLEASE!!!!
Nitinol is an alloy of nickel and titanium, it has two structures, austenite or martensite, and nickel and titanium are elements, that contain 28 and 22 electrons respectively.
What is nitinol?Nitinol is an alloy containing an equal quantity of elements of nickel and titanium.
It is a superelastic alloy and has shape memory capacity.
It retains its shape after reforming into another shape by an increase in temperature.
Thus, the difference is that Nitinol is an alloy of nickel and titanium, it has two structures, austenite or martensite, and nickel and titanium are elements, that contain 28 and 22 electrons respectively.

Alexander spent a total of 12.5 hours on a science project for the Science Fair. His sister, Laura, spent 16.6 hours on a science project. How many more hours did Laura spend on her project than Alexander spent on his?
Answer:
4.1 I think
Step-by-step explanation:
I just subtracted in my head
Answer:
4.1 hours
Step-by-step explanation:
Laura spent 4.1 more hours on her project than Alexander spent on his. If we split each number into 2 parts (like this: 12.5 -> 12 and .5; 16.6 -> 16 and .6) then we can subtract 12 from 16 and .5 from .6 to get 4 and .1. we add those together to get 4.1

A snowplow has maximum speed of 45 miles per hour on a dry highway. Its maximum speed decreases by 1.6 miles per hour for every inch of snow on the highway. According to this model, at what snow depth will the snow plow be unable to move?
Answer:
28.125
Step-by-step explanation:
If it is going 45mph and every hour it decreases 1.6mph per inch of snow added. so 45 divided by 1.6 is 28.125.

The length of a rectangle is four times its width. Its perimeter is no greater than 170 cm. Find the greatest possible dimensions of the rectangle.
Step-by-step explanation:
let the length be =L
the width is 4 × the length
so the width will be 4L
the formular for the perimeter of a rectangle is =2(L +W)
170=2(L +4L)
170=2(5L)
170=10L
17=L
so the width is 4 × the length
17×4
=68
L=17
W=68
The mass of a cube, M (kg), is proportional to the cube of the length of its edge, L(m). The mass of the cube is 80 kg when the length of its edge is 35 cm. Work out M (to 2 DP) when L=0.3 m
Answer:
M=K*L
(K is the constant we use)
when L=35cm, M=80,
meaning K=80/0.35=228.571428571
so when L=0.3
we do 0.3*228.571428571=68.5714285713
rounded to 2dp= 68.57kg
9514 1404 393
Answer:
50.38 kg
Step-by-step explanation:
The mass is proportional to the cube of edge length, So, if the edge length is decreased by a factor of 30/35 = 6/7, the mass is decreased by a factor of (6/7)³. That is, the smaller cube will have a mass of ...
(80 kg)(6/7)³ ≈ 50.38 kg
__
If you want to write an equation, you can write the equation for the proportionality:
M = kL³
80 kg = k(0.35 m)³
k = 80/0.35³ kg/m³
Then for the shorter length, we have ...
M = k(0.3 m)³ = 80(0.3/0.35)³ kg = 80(6/7)³ kg ≈ 50.38 kg . . . . as above

The sum of two consecutive integers is 41. What are the two integers?
Answer:
Step-by-step explanation:
Let the smaller of two consecutive integer be x therefore other integer is x+ 1
As per statement the sum of two consecutive integers is 41. To find out the integers.
x + (x + 1) = 41
x + x + 1 = 41
2x + 1 = 41
2x = 41 - 1
2x = 40
x = 40/2
x = 20
The smaller of two consecutive integers is 20, thus other integer is x + 1 = 20 + 1 = 21
The two consecutive integers are 20 and 21
Answer the two consecutive integers are 20 and 21

Determine whether each sequence is an arithmetic sequence. Write yes or no. Explain. 7, 10, 13, 16, ...
Answer:
The given sequence is an arithmetic sequence.
Step-by-step explanation:
Given sequence is:
7, 10, 13, 16, ...
Here
[tex]a_1 = 7\\a_2 = 10\\a_3 = 13\\a_4 = 16[/tex]
In order for a sequence to be an arithmetic sequence the common difference between the consecutive terms of the sequence should be same. Common difference is denoted by d.
So,
[tex]d = a_2 - a_1 = 10-7 = 3\\d = a_3 - a_2 = 13-10 = 3\\d = a_4-a_3 = 16-13 = 3[/tex]
As we can see that the common difference is same for consecutive terms.
The given sequence is an arithmetic sequence.

What is the value of b?
Answer:
Improper fraction: 19/3
Mixed number: 6 1/3
Step-by-step explanation:
If these two lines are perpendicular, their slopes are negative reciprocals of each other. The line would be something like:
y = (1/12)x+b
So plug in the coordinate values.
6 = (1/12)(-4)+b
6 = (-1/3)+b
6 1/3 = b
how to get the answer to 3 1/2 ÷ 5 ( I need I step by step explanation :D )
Answer: .28
Step-by-step explanation: First turn the mixed number into an improper fraction. so 3x2+1=7, 7 is the the top and the bottom stays the same (2) so it would now be 7/2 divided by 5 which would equal .28
I hope this helps
