Answer:
Relation only.
Step-by-step explanation:
it is not a function because there is a repeated -2 in the x-values of the ordered pairs.
Answer:
ACB=90-62
ACB=28
Therefore we say CAB is 28.
Answer:
The probability that the sample proportion is more than 0.35 believe movie trailers reveal too much is 0.1539.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
![\mu_{\hat p}=p](https://tex.z-dn.net/?f=%5Cmu_%7B%5Chat%20p%7D%3Dp)
The standard deviation of this sampling distribution of sample proportion is:
![\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}](https://tex.z-dn.net/?f=%5Csigma_%7B%5Chat%20p%7D%3D%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%7D)
The information provided is:
<em>p</em> = 0.32
<em>n</em> = 250
Since the sample size is quite large, i.e. <em>n</em> = 250 > 30, the central limit theorem can be used to approximate the sampling distribution of sample proportion by a Normal distribution.
Compute the probability that the sample proportion is more than 0.35 believe movie trailers reveal too much as follows:
![P(\hat p>0.35)=P(\frac{\hat p-\mu_{\hat p}}{\sigma_{\hat p}}>\frac{0.35-0.32}{\sqrt{\frac{0.32(1-0.32)}{250}}})](https://tex.z-dn.net/?f=P%28%5Chat%20p%3E0.35%29%3DP%28%5Cfrac%7B%5Chat%20p-%5Cmu_%7B%5Chat%20p%7D%7D%7B%5Csigma_%7B%5Chat%20p%7D%7D%3E%5Cfrac%7B0.35-0.32%7D%7B%5Csqrt%7B%5Cfrac%7B0.32%281-0.32%29%7D%7B250%7D%7D%7D%29)
![=P(Z>1.02)\\=1-P(Z](https://tex.z-dn.net/?f=%3DP%28Z%3E1.02%29%5C%5C%3D1-P%28Z%3C1.02%29%5C%5C%3D1-0.84614%5C%5C%3D0.15386%5C%5C%5Capprox%200.1539)
Thus, the probability that the sample proportion is more than 0.35 believe movie trailers reveal too much is 0.1539.
Answer:
-4/5
Step-by-step explanation:
In a line, the slope is the coefficient to x.
In the standard linear equation, f(x) = mx + b, m is the slope.
Since the equation is f(x)= -4/5x + 2, -4/5 is the slope because it is the coefficient to x.
So, the slope is -4/5
