In geometry, an undefined term is a basic figure that cannot be defined in terms of other figures.
The undefined terms in geometry are: point, line and plane.
Since you have not attached any figures, I cannot tell you which one is correct. Just choose the figure that is either a point, a line or a plane.
Answer:
The probability of observing a sample mean of 31.1 grams of fat per pound or less in a random sample of 34 farm-raised trout is 0.227
Step-by-step explanation:
Let X be the sample mean of fat in 34 farm-raised trout
The probability of observing a sample mean of 31.1 grams of fat per pound or less in a random sample of 34 farm-raised trout can be stated as:
P(X<31.1 grams) = P(z<z*)
where z* is the z-statistic of sample mean of 31.1 grams fat.
z* can be calculated as follows:
z*= where
- M is the average grams of fat per pound (32)
- s is the standard deviation (7)
- N is the sample size (34)
Then z*= ≈ −0.7497
and P(z<z*) ≈ 0.227
The probability of observing a sample mean of 31.1 grams of fat per pound or less in a random sample of 34 farm-raised trout is 0.227

Answer:
x = - 7, y = 6
Step-by-step explanation:
7x + 7y = - 7 -----> equation 1
- 10x - 7y = 28 -----> equation 2
Add equations 1 & 2,
7x + 7y = - 7
- 10x - 7y = 28
___________
- 3x + 0 = 21
- 3x = 21
x = 21 / - 3
x = - 7
Substitute x = - 7 in equation 1,
7x + 7y = - 7
7y + 7x = - 7
7y + 7 ( - 7 ) = - 7
7y - 49 = - 7
7y = - 7 + 49
7y = 42
y = 42 / 7
y = 6
