Step 1) turn 1.9 into an improper fraction.
= 19/10
step 2) find a least common denominator between 10 and 12.
= 60
(10x6 and 12x5)
step 3) convert the fractions so they have the same denominator.
= 19x6 is 114.
10x6= 60.
= 11x5 is 55.
12x5 is 60.
now you have your new fractions.
step 4) subtract.
= 114/60 - 55/60 is 59/60.
step 5) simplify.
the answer is either 0.9833... (3 repeating) or just 59/60 (you can't simplify the fraction any further).
Answer:
Test statistic z= 1.708
Step-by-step explanation:
given that a television network is deciding whether or not to give its newest television show a spot during prime viewing time at night. If this is to happen, it will have to move one of its most viewed shows to another slot.
Sample size n = 827
Sample proportion p = ![\frac{438}{827} \\=0.5297](https://tex.z-dn.net/?f=%5Cfrac%7B438%7D%7B827%7D%20%5C%5C%3D0.5297)
![H_0: p =0.5\\H_a: p >0.5](https://tex.z-dn.net/?f=H_0%3A%20p%20%3D0.5%5C%5CH_a%3A%20p%20%3E0.5)
(right tailed test)
This is because they would be interested if more than half viewers are ready for the change
Test statistic = Z = p difference/std error
p difference = 0.0297
Std error =![\sqrt{\frac{pq}{n} } \\=\sqrt{\frac{0.5*0.5}{827} } \\=0.0174](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Bpq%7D%7Bn%7D%20%7D%20%5C%5C%3D%5Csqrt%7B%5Cfrac%7B0.5%2A0.5%7D%7B827%7D%20%7D%20%5C%5C%3D0.0174)
Z =1.708
p valu e= 0.9562
Since p >0.05 we fail to reject H0
Test statistic z= 1.708
Answer: 96 games
Step-by-step explanation: You want to find out how many games the team won if their win to loss ratio is 16 to 11. Because you want to find the total, adding 16 and 11 gives 27. Multiplying 16/27 by 162 gives 96, the desired wins. Hope this helps! (Could I please have brainliest?)
A linear equation in slope-intercept form from two points is given by (y - y1)/(x - x1) = (y2 - y1)/(x2 - x1).
Here, y1 = 2200, x1 = 12, y2 = 3000 and x2 = 10, then
(y - 2200)/(x - 12) = (3000 - 2200)/(10 - 12)
(y - 2200)/(x - 12) = 800/-2 = -400
y - 2200 = -400(x - 12)
y = -400x + 4800 + 2200
y=-400x+7000
I think it might be 56y^2 but I could be wrong
