Hello!
The length and width are given.
We know the formula for calculating perimeter :
Let's solve!
- Perimeter = 2(123 + 17k + 24k - 49)
- Perimeter = 2(41k + 74)
∴ The perimeter is 82k + 148.
Answer:
i dunno
Step-by-step explanation:
Answer:
Use the normal distribution if the population standard deviation is known.
Use the student's t distribution when the population standard deviation is unknown.
Explanation:
A mound-shaped distribution refers to the normal distribution.
A good sample size for testing against the normal distribution should be
n >= 30.
The condition for the sample size is satisfied.
However, we are not given the population standard deviation, therefore it is assumed to be unknown.
Therefore the student's t distribution should be used.
Answer:
x = 1.3
Step-by-step explanation:
15 - 4x = 2(3x + 1)
15 - 4x = 6x + 2
-2 -2
--------------------------
13 - 4x = 6x
+4x +4x
--------------------------
13 = 10x
/10 /10
---------------------------
1.3 = x
