Answer:
Step-by-step explanation:
Sample data
204.999 206.149 202.102 207.048 203.496 206.343 203.496 206.676 205.831
N=9
Sum, Σx: 1846.14
Mean, μ: 205.12666666667
Variance, s^2: 2.6217475555555
Std dev = s = 1.619
The sample mean follows a t distribtion with df =8
Mean difference = 205.13-204.8 = 0.50
Std error = std dev/sqrt n = 0.540
Test statistic = Mean diff/se = 0.9259
p value = 0.1907 (one tailed at 95%)
Since p >0.05 we accept null hypothesis.
We cannot conclude that the mean shade of Mezza Perla tile (µ) is greater than 204.8
Answer:
Step-by-step explanation:
2x3 − 5x2 + 25
2x³ -5x²+25
2x³ -5(x²-5)
Answer:
y = 9/5 x -4
Step-by-step explanation:
first find slope or m
slope is change in y over the change in x
-4-5/0-5 =-9/-5 = 9/5
the (0, -4) is the y intercept or b
Answer: son, estoy, estas, es, son, estamos, son, estan
Step-by-step explanation:
If it is talking about someone else then try to use, son. Like the first one. For words for yo use words like estoy. I don´t really know how to explain them but they make sense.
You can see that the answers(y) of f(x) were Subtracted by a factor of 2 to make the answers(y) of g(x).
example: 9-2=7 81-2=79
when a number is added to or subtracted from a function the graph will make a horizonal or vertical shift. therefore C. is correct
