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:
8/625
Step-by-step explanation:
bc i guessed and its says 8/625
24 , I think
Btw I like your pfp, but do you even know who the character is ;_;
<h3>answer</h3>
we assume the height of the triangle is x,
so the base length will be x+4
the triangle area will be area = 1/2 ( base * height)
48 = 1/2 (x + 4) x
96 = x2 + 4x
96 + 4 = x2 + 4x + 4
100 = (x + 2)2
10 = x + 2 (for the square 100, we ignore the -10, minus is meaningless in length )
x = 8
x + 4 = 8 + 4 = 12
so the height for the triangle is 8 unit, base is 12 unit,
brainliest ♥️
It is thousandths because it t is 3 plac s the the left
