Answer:
The answer is in the explanation
Step-by-step explanation:
Mean value = 
= 438
(a) The data appeared to be centered towards 438.
There are little or no skew.
There is no outliers.
(b) yes
(c) standard deviation = s = 14.8955
95% confidence interval = 
=
= (430.3415, 445.6585)
(d) Test statistic
t = 
t = -3.3216
p -value is correctly given in option b.
No, 450 is not a plausible valaue.
Answer:
-2 and 3
Step-by-step explanation:
The x-intercepts or where the graph cuts the x-axis represents the zeros of y = x² - x - 6.
Thus, the zeros are -2 and 3. This is where the graph cuts the x-axis.
Therefore, the solutions of the graph are -2 and 3.
Since a^2 - b^2 = 1, the value of y = 1 because x=1 and 1^2 - 1^2 = 0
3(3x-10)=5(x+10)
9x-30=5x+50
+30 +30
9x = 5x+80
-5x -5x
4x=80
/4 /4
x=20
Answer:
9,338 is the product of the equation
