The probabilities will be 0.1081 , 0.676, 0.863, 0.605 respectively.
let us consider, the chances of getting stem be a success(S) and not getting it be a failure(F) , and the total probability be 1 .
as per the statement 26% students are major in stem
total students selected randomly are 36.
∴ P(S) = 0.26
P( F) = 1 - 0.26 = 0.74
Now the binomial probability of success is given by
[tex]P(x) = C^{n} _{x} S^{x} F^{n-x}[/tex]
where C is for the combination formula
S is changes of success
F is chances of failure
x = no. of times success
n = total times the experiment done
From the provided information we can solve each case as follows :
A) exactly 7 of them major in stem
P(7) = [tex]C^{36} _{7} (0.26)^{7} (0.74)^{29}[/tex]
= 0.1081
B)at most 10 of them major in stem
it means P(0,1,2...10)
∴ P = P(0) + P(1) +......+P(10)
P = 0.676
C) at least 7 of them major in stem.
it means P(7,8,9...36)
∴ P = P(7) + P(8) + ...+ P(36)
P = 0.863
D) between 9 and 15 (including 9 and 15) of them major in stem.
In this case we subtract P(0,1,2...8) from P(0,1,2,...15)
and get P(9,10,11,...15)
∴ P(9,10,11,...15) = P(0,1,2,...15) - P(0,1,2...8)
= 0.987 - 0.382
= 0.605

let nn denote the smallest positive integer that is divisible by both 44 and 9,9, and whose base-1010 representation consists of only 44's and 99's, with at least one of each. what are the last four digits of nn?
The last four digits of the number nn are 4944
Given that,
Let nn stand for the lowest positive integer that can be represented in base-1010 using only the numbers 44 and 99, with at least one of each. This number must be divisible by both 44 and 9,9.
The last two digits of n must be divisible by 4 for n to be divisible by 4.
So last digits of n will be 44.
And for divisiblity by 9, sum of all digits of n has to be divisible by 9.
As two digits are fixed and their total is 8, next feasible total will be 45 so 9 can be atleast one time in n.
And as statement says n has to be smallest number n will be 4444444944
So last 4 digits of n are 4944.
Therefore, nn's last four numbers are 4944.

A right triangle has a hypotenuse of length 10 centimeters. If one angle is 40°, find the length of each leg.
If a right triangle has a hypotenuse of length 10 centimeters. If one angle is 40 degrees, the length of the each legs are 6.43 centimeter and 7.66 centimeter
The hypotenuse of the right triangle = 10 centimeter
The measure of angle = 40 degree
Here we have to use the trigonometric functions
sin θ = Opposite side / Hypotenuse
Substitute the values in the equation
sin 40 = Opposite side / 10
Opposite side = 10 × sin 40
= 6.43 centimeter
Similarly
cos θ = Adjacent side / Hypotenuse
Substitute the values in the equation
cos 40 = Adjacent side / 10
Adjacent side = 10 × cos40
= 7.66 centimeter
Hence, if a right triangle has a hypotenuse of length 10 centimeters. If one angle is 40 degrees, the length of the each legs are 6.43 centimeter and 7.66 centimeter

an urn contains 6 blue balls and 6 orange balls. in how many ways can we select 2 blue balls and 2 orange balls from the urn?
The no. of ways to select the 2 blue balls and 2 orange balls from the urn is 0.4545
No. of Blue balls in the urn = 6
No. of Orange balls in the urn = 6
Total no. of balls in the urn = No. of blue balls + No. of orange balls

No. of blue balls to be selected = 2
No. of orange balls to be selected = 2
No. of balls to be selected = 4
The total. no of ways 4 balls can be selected =[tex]^{12}C_{4}[/tex]
The No. of ways 2 blue balls can be selected = [tex]^{6}C_{2}[/tex]

I need to paint a straight face consisting of six panels he has a green red and magenta paint and each panel should be painted with only one color how many ways are there to paint the fence
There are 20 ways to paint the fence consisting of six panels each with one color out of green, red, and magenta.
There is a total of 6 panels and 3 paint colors and each panel has to be painted with only 1 color.
∴ Total number of panels = 6
Total number of colors = 3 (green, red, and magenta)
To calculate the number of ways to paint 6 panels with one of the 3 colors, the formula of combination is used. Combinations are ways of selecting objects from a group or collections, in a way that the order of the objects does not matter.
The number of ways or the combinations of 6 panels taken with each color out of 3 at a time is given by [tex]^6C_3[/tex]
[tex]^6C_3[/tex] = 6! / [3! (6-3)!]
[tex]^6C_3[/tex] = (6*5*4*3*2*1) / [3*2*1 (3)!]
[tex]^6C_3[/tex] = 720 / (6*6)
[tex]^6C_3[/tex] = 720 / 36
[tex]^6C_3[/tex] = 20

In the recent year, 51.9 billion aluminum cans were recycled. About how many cans per week is this?
The number of cans that are recycled is approximately 1 billion cans in 1 week.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that 51.9 billion aluminum cans were recycled.
Therefore, the rate of recycled the can is;
51.9 billion / 1 year
We know that 1 year has 52 weeks
Then
51.9 billion / 1 year x 1 year / 52 weeks
= 51.9 (1) billion / 1 (52 ) weeks
= 51.9 billion/ 52 weeks
= 1 billion/ 1 week

Find the value of x and 3x
Step-by-step explanation:
remember, the sum of all angles in a triangle is always 180°.
now let's consider the white, "cut-out" triangle on the left side.
the purple one angles at the top and bottom corner are 45°.
the withe outer angles at the same corners (they are the inner angles for the white triangle) are complementary angles (together they have 90°) to the purple ones, because due to the equal angles at the top and bottom we know the connection between the 2 45° angles (the white baseline) is at a 90° angle to the 45° to 135° sides.
so the 2 baseline angles of the left white triangle are also 45° (45+45 = 90).
and that means that the third white angle is
180 - 45 - 45 = 90°.
and because a full circle around the 3x° point must have 360° (as any full circle), we know that both angles (90° and 3x°) together are 360°.
360 = 90 + 3x
270 = 3x
x = 90°
3x = 270°

(h, k) = vertex of the graph a = this value determines if the graph opens up or opens down.h = horizontal translation factork = vertical translation factorFrom the graph, we know that:
Vertex (h, k) = (3, 5)
Substitute h = 3 and k = 5 into the equation, y = a|x – h| + k:
y = a|x - 3| + 5
A point on the graph is (5, 7). To find the value of a, substitute x = 5 and y = 7 into the equation y = a|x - 3| + 5:

how many 44-digit positive integers (that is, integers between 10001000 and 99999999, inclusive) having only even digits are divisible by 55?how many 44-digit positive integers (that is, integers between 10001000 and 99999999, inclusive) having only even digits are divisible by 55?
There are 100 4-digit positive integers are possible between 1000 and 9999.
Our first step is to divide the four digit number into four places: tens, hundreds, and thousands.
To solve this problem, we must start from the right-hand side and find how many even numbers should be placed where the desired answer can be obtained.
There are a total of [0, 2, 4, 6, and 8] objects
There should only be one digit on one place, since it is the only digit that makes the number divisible by five
There are 1 ways to fill the one's place, so the total number is 1.
It is possible to take any number from the given sets of even numbers in the tens place,
There are five ways to fill one place, so there are five ways to fill it.
Taking a look at the hundreds place,
All numbers can be placed in the hundreds place from the given sets, so all numbers can be taken from the hundreds place.
Therefore, there are five ways to fill the hundreds place.
Taking a look at the thousands,
It is possible to fill thousands of places with 4 numbers from a given set of even numbers.
Therefore, there are four ways to fill the thousands place
The next step is to use the concept of factorial to find the number of ways to make a 4-digit number from even numbers that are divisible by 5.
To fill the respective places, we will multiply all the ways we calculated
= 4 × 5 × 5 × 1
= 100
Hence, there 100 4-digit positive integers possible.
