Answer:
2
Step-by-step explanation:
If 1 = 1.5
2 = 3
That is the answer
Answer: I don't know
Step-by-step explanation: Jk, the answer is X = 3 or 1/3
/ = Fraction
^ = Power-of
* = Multiply
Move all the terms to the left then multiply the parentheses:
(5x+3) (10-2) - (7x) * (8x) = 0
(50x^2-10x+30x-6)-7x*88x
Then multiply variables:
(50x^2-10x+30x-6)-56x^=0
Now add all the numbers together:
6x^2+20x-6=0
= 256x
Use the following formula:
x1=−b−Δ√2a
x2=−b+Δ√2a
Set up the problem:
√ =√256=16
Part 1: -20-16/2x-6 = -36/-12 = 3
Part 2: -20+16/2x-6 = -4/-12 = 1/3
Answer:
The probability is 0.057797
Step-by-step explanation:
Consider the provided information.
It is given that true percentage of voters who vote for the proposition is 63%,
Let p is probability of success.
According to the binomial distribution:
![P(x;p,n)=^nC_x(p)^x(1-p)^{(n-x)}](https://tex.z-dn.net/?f=P%28x%3Bp%2Cn%29%3D%5EnC_x%28p%29%5Ex%281-p%29%5E%7B%28n-x%29%7D)
Substitute n=7, p=0.63 and x=2 in the above formula.
![P(x;p,n)=^7C_2(0.63)^2(1-0.63)^{(7-2)}](https://tex.z-dn.net/?f=P%28x%3Bp%2Cn%29%3D%5E7C_2%280.63%29%5E2%281-0.63%29%5E%7B%287-2%29%7D)
![P(x;p,n)=\frac{7!}{2!5!}(0.3969)(0.37)^{5}\\P(x;p,n)=21(0.3969)(0.37)^{5}\\P(x;p,n)=0.0577974947199\\P(x;p,n)\approx0.057797](https://tex.z-dn.net/?f=P%28x%3Bp%2Cn%29%3D%5Cfrac%7B7%21%7D%7B2%215%21%7D%280.3969%29%280.37%29%5E%7B5%7D%5C%5CP%28x%3Bp%2Cn%29%3D21%280.3969%29%280.37%29%5E%7B5%7D%5C%5CP%28x%3Bp%2Cn%29%3D0.0577974947199%5C%5CP%28x%3Bp%2Cn%29%5Capprox0.057797)
Hence, the probability is 0.057797
Step-by-step explanation:
In this problem, all we have to do is replace x and y with the values we've been given.
It can be helpful to think of 3x as 3 * x (which is the same exact thing), so I'll write it out that way.
3*x - 4*y
(replace)
3*4 - 4*3
(multiply (doing this step first because of PEMDAS))
12 - 12
(subtract)
0
