Answer:
B
Step-by-step explanation:
The answer is B, -12.
Please give me brainliest.
-12^2 --> -144
-144+144 = 0
Therefore, the answer is B, -12.
This is true, since ab=cd and ef must = ef the. Ab+ef = cd+ ef
Answer:
I would say B
Step-by-step explanation:
when you are going down you tend to go faster because of gravity. So you would go down, up, down, up, and a little down. This would make B the answer because the speed is increasing when it goes down so that is the only answer that would make sense. Hope this helped! Have a good day! :)
Answer:
<em>The input when the output is 17 is x=6.</em>
Step-by-step explanation:
<u>Functions</u>
Assume the input is called x and the output is the function f(x). Two times the input is 2x. 5 more than that is 2x+5.
Knowing the output of the function is 5 more than 2 times the input, we can write the function as:
f(x)=2x+5
Now find the input x when the output is 17:
17=2x+5
Swap sides of the equation:
2x+5=17
Subtract 5:
2x=17-5=12
Divide by 2:
x=12/6=6
The input when the output is 17 is x=6.
Answer:
(a) The confidence interval is 0.5321<π<0.6679
(b) It can be said, with more than 95% certainty, that the majority of the taxpayers feel that the taxes are too high.
Step-by-step explanation:
First, we calculate the proportion p
![p=120/200=0.6](https://tex.z-dn.net/?f=p%3D120%2F200%3D0.6)
For a 95% confidence interval, z-score is 1.96.
The lower and upper limit of the confidence interval can be calculated as
![LL = p-z*\sigma_{p}=p-z*\sqrt{\frac{p(1-p)}{N} } \\LL=0.6-1.96*\sqrt{\frac{0.6*0.4}{200} }=0.6 - 1.96*0.0346=0.6-0.0679=0.5321\\\\UL=p+z*\sigma_{p}=p+z*\sqrt{\frac{p(1-p)}{N} } \\UL=0.6+0.0679=0.6679](https://tex.z-dn.net/?f=LL%20%3D%20p-z%2A%5Csigma_%7Bp%7D%3Dp-z%2A%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7BN%7D%20%7D%20%5C%5CLL%3D0.6-1.96%2A%5Csqrt%7B%5Cfrac%7B0.6%2A0.4%7D%7B200%7D%20%7D%3D0.6%20-%201.96%2A0.0346%3D0.6-0.0679%3D0.5321%5C%5C%5C%5CUL%3Dp%2Bz%2A%5Csigma_%7Bp%7D%3Dp%2Bz%2A%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7BN%7D%20%7D%20%5C%5CUL%3D0.6%2B0.0679%3D0.6679)
The confidence interval is 0.5321<π<0.6679
(b) The lower limit is above 53%, so it can be concluded that the majority of the taxpayers feel that the taxes are too high.
