Answer: 0.3061.
Step-by-step explanation:
Given : The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean , the actual temperature of the medium, and standard deviation .
Let X be the random variable that represents the reading of the thermometer.
Confidence level :
We know that the z-value for 95% confidence interval is 1.96.
Then, we have
But all readings are within 0.6° of .
So,
Hence, the required standard deviation will be
Don’t go to That link but I think it is d
Answer:
You can start by distributing the 3 to the m+4
(3m + 12)
Now you can add on the -5m and simplify
(3m+12-5m)
-2m+12
Answer:
D. 1720 mm^2.
Step-by-step explanation:
This consists of 5 surfaces.
Area of 2 triangles + area of base + area of the side + area of the sloping side.
= 2 * 1/2 * 8 * 15 + 40*17 + 8*40 + 15*40
= 120 + 680 + 320 + 600
= 1720.
Answer:
a=3.33m/s^2
Step-by-step explanation:
F=ma
a=F/m
To find Force you have to subtract the gravitational force by the air force
F=600-400
F=200N
m=60kg
Plug in the values:
a=200N/60kg
a=3.33m/s^2
