Answer:
Step-by-step explanation
Hello!
Be X: SAT scores of students attending college.
The population mean is μ= 1150 and the standard deviation σ= 150
The teacher takes a sample of 25 students of his class, the resulting sample mean is 1200.
If the professor wants to test if the average SAT score is, as reported, 1150, the statistic hypotheses are:
H₀: μ = 1150
H₁: μ ≠ 1150
α: 0.05
![Z= \frac{X[bar]-Mu}{\frac{Sigma}{\sqrt{n} } } ~~N(0;1)](https://tex.z-dn.net/?f=Z%3D%20%5Cfrac%7BX%5Bbar%5D-Mu%7D%7B%5Cfrac%7BSigma%7D%7B%5Csqrt%7Bn%7D%20%7D%20%7D%20~~N%280%3B1%29)
The p-value for this test is 0.0949
Since the p-value is greater than the level of significance, the decision is to reject the null hypothesis. Then using a significance level of 5%, there is enough evidence to reject the null hypothesis, then the average SAT score of the college students is not 1150.
I hope it helps!
Answer:
u = 3
Step-by-step explanation:
I hope I've helped you.
Midpoint formula
mid of (x1,y1) and (x2,y2) is
so
(22,15)=
therefor
22=
and
15=
slv each
22=
times both sides by 2
44=18+x1
minus 18 both sides
26=x1
15=
times both sides by 2
30=6+y1
minus 6
24=y1
the other point is (26,24)
Answer:
Vertical asymptote: 
Horizontal asymptote: 
or x axis.
Step-by-step explanation:
The rational function is given as:
Vertical asymptotes are those values of 
for which the function is undefined or the graph moves towards infinity.
For a rational function, the vertical asymptotes can be determined by equating the denominator equal to zero and finding the values of .
Here, the denominator is 
Setting the denominator equal to zero, we get
Therefore, the vertical asymptote occur at 
.
Horizontal asymptotes are the horizontal lines when tends towards infinity.
For a rational function, if the degree of numerator is less than that of the denominator, then the horizontal asymptote is given as 
.
Here, there is no term in the numerator. So, degree is 0. The degree of the denominator is 3. So, the degree of numerator is less than that of denominator.
Therefore, the horizontal asymptote is at or x axis.
Answer:
Step-by-step explanation:
The answer would be A because the hypothesis of a conditional statement is the statement after the "if", but before the "then".
