A. we use the z statistic to solve this problem
z = (x – u) / s
We calculate the value of the sample mean u and standard deviation
s:
u = $30 * 304 = $9120
s = $21 * 304 = $6384
z = (9,600 – 9120) / 6384
z = 0.075
From the normal tables using right tailed test,
P = 0.47
B. At worst 11% means P = 0.11, so the z value at this is
z = -1.23
-1.23 = (x – 9120) / 6384
x = 1267.68
Answer:
26 degrees Celcius
Step-by-step explanation:
The minimum temperature is -11
The maximum temperature is 15
to get from -11 to 0: add 11
to get from 0 to 15: add 15
11+15 = 26
The answer is 8 and 1/21 in fixed fraction.
and decimal form it would be 8.047619
Answer:
There is no solution because the graphs do not intersect
Step-by-step explanation:
Both of theses equations do intersect with one another when graphed. In conclusion, there is no solution.
Answer:
if you mean the face of the triangle the area equal 40 by 5×8=
and the little triangle on the left his area is 6
if you want the full area of prymaid its 24+6+6+40+32=108 its all figure areas sorry i cant understand engilish very well so i write all that
