Answer:
Step-by-step explanation:
Using the concept of binomial probability distribution to approach the question.
Mathematically; P(X=r) = nCr P^r (1-p)^n-r
The steps is as shown in the attached file.
Answer:
5,1
Step-by-step explanation:
7x + 4y = 39
2x + 4y = 14
since, the 4y same for both equation then we can eliminate the 4y by subtracting the two equation
7x + 4y = 39
2x + 4y = 14
---------------- -
5x + 0 = 25
5x = 25
x = 25/5 = 5
then we can input (subtitute) the value of x into the equation, I choose 2x + 4y = 14
2x + 4y = 14
2(5) + 4y = 14
10 + 4y = 14
4y = 14 - 10
4y = 4
y = 4/4 = 1
or if your teacher ask you to use elimination to find the value of x we can write like this
7x + 4y = 39
2x + 4y = 14
make the coeficient of x in both equation same
7x + 4y = 39 (x2)
2x + 4y = 14 (x7)
so
14x + 8y = 78
14x + 28y = 98
--------------------- -
0 - 20y = -20
-20y = -20
y = (-20)/(-20) = 1 (same answer right)
so the correct answe is
(5,1)
Answer:
i dont know sry for the bother
Step-by-step explanation:
Answer:
r ≅ 3.00
Step-by-step explanation:
First we need to get the formula for finding the volume of sphere. The formula is:

Now to find for the radius, we need to input the value that we know into the formula.

Now we multiply both sides by 3/4.


Now divide both sides by π.


To find r, we finally get the cube root of both sides.
![\sqrt[3]{r^{3} }= \sqrt[3]{27.01}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Br%5E%7B3%7D%20%7D%3D%20%5Csqrt%5B3%5D%7B27.01%7D)
r ≅ 3.00
