Answer:
y = 5/2x -15
Step-by-step explanation:
5x - 2y = 30
-2y = -5x + 30
y =
x -15
You'd do the same as in
brainly.com/question/2700999lemme hmmm redo the fractions... and as I said, you flip them around as needed
![\cfrac{7.6cm}{1y}\cdot \cfrac{1m}{100cm}\cdot \cfrac{1km}{1000m}\cdot \cfrac{1,000,000y}{1myr}](https://tex.z-dn.net/?f=%5Ccfrac%7B7.6cm%7D%7B1y%7D%5Ccdot%20%5Ccfrac%7B1m%7D%7B100cm%7D%5Ccdot%20%5Ccfrac%7B1km%7D%7B1000m%7D%5Ccdot%20%5Ccfrac%7B1%2C000%2C000y%7D%7B1myr%7D)
notice, we flipped them some, so the unit ends either above or below
in order to cancel the one on the left
A number to the power of 1/2 is the same as square root. 48 simplifies to 16*3. The square root of 16 is 4. So the 4 comes out and the 3 is left inside. So the answer is C.
Answer: 0.4402
Step-by-step explanation:
Given : The proportion of the registered voters in a country are Republican = P=0.50
Sample space = 36
The test statistic for proportion :-
![z=\dfrac{p-P}{\sqrt{\dfrac{P(1-P)}{n}}}](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7Bp-P%7D%7B%5Csqrt%7B%5Cdfrac%7BP%281-P%29%7D%7Bn%7D%7D%7D)
For p= 0.477
![z=\dfrac{0.477-0.50}{\sqrt{\dfrac{0.50(1-0.50)}{36}}}\approx-0.276](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B0.477-0.50%7D%7B%5Csqrt%7B%5Cdfrac%7B0.50%281-0.50%29%7D%7B36%7D%7D%7D%5Capprox-0.276)
For p= 0.58
![z=\dfrac{0.58-0.50}{\sqrt{\dfrac{0.50(1-0.50)}{36}}}\approx0.96](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B0.58-0.50%7D%7B%5Csqrt%7B%5Cdfrac%7B0.50%281-0.50%29%7D%7B36%7D%7D%7D%5Capprox0.96)
Now, the probability that the proportion of freshmen in the sample is between 0.477 and 0.58 (by using the standard normal distribution table):-
![P(0.477](https://tex.z-dn.net/?f=P%280.477%3Cx%3C0.58%29%3DP%28-0.276%3Cz%3C0.96%29%5C%5C%5C%5C%3DP%28z%3C0.96%29-P%28z%3C-0.276%29%5C%5C%5C%5C%3D0.8314724-%200.391274%3D0.4401984%5Capprox0.4402)
Hence, the probability that the proportion of freshmen in the sample is between 0.477 and 0.580 = 0.4402
