<span>The first thing to do here is simplify both sides. X=4/9 is simplified, but you can simplify the other side by canceling out the (x-2) in the numerator and denominator.
</span><span>The expression should be (x + 4)(x - 2)/9(x - 2)= (x + 4)/9. After simplification by (x - 2) , the remainder is (x + 4)/9. When x = -4, both sides equal to zero When x = 0 , both sides equal to 4/9

I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:
.441558442 m =Wavelength
Step-by-step explanation:
The formula to find the speed of a wave is found by
Speed = Wavelength x Frequency where the frequency is in HZ and the wavelength is in meters
340 = Wavelength*770
Divide each side by 770
340/770 = Wavelength*770/770
.441558442 m =Wavelength
10/12 can be simplified down
I would divide both sides by 2 for starters, then you can see if it needs to be simplified more
10/2=5
12/2=6
Since you have an odd and an even number, you can't simplify it any more, as 5 and 6 have no common numbers.
The correct answer is A. 5/6
Hope this helps!

Answer:
The width of the 95% confidence interval for p is 0.2496
Step-by-step explanation:
Taking into account that the proportion of the students from the sample that prefer the taste of fresh-brewed coffee is calculated as:
p' = 35/60 = 0.5833
Because there are 60 students in the sample and 35 prefer the taste of fresh brewed coffee.
So, the width of the 95% confidence interval for p is calculated as:
Where n is the number of the students in the sample and 1.96 is the z values that satisfy that:
2P(Z>1.96) = 1 - 0.95 = 0.05
Then, replacing p' by 0.5833 and n by 60, we get:
Finally, the width of the 95% confidence interval for p is 0.2496
