Answer:
The sum of the first five classroom numbers in a row is 5k + 20
Step-by-step explanation:
Since the smallest classroom number on the side of the building is numbered k and each consecutive odd integer is separated by a difference of
2.
Therefore:
k is the first class room.
k + 2 is the second class room.
k + 4 is the third class room.
k + 6 is the third class room.
k + 8 is the fifth class room.
The sum of the five consecutive class rooms are given as:
k + (k + 2) + (k + 4) + (k + 6) + (k + 8)
collecting alike terms we get
= k + k + k + k + k + 2 + 4 + 6 + 8
= 5k + 20
Therefore, The sum of the first five classroom numbers in a row is 5k + 20.
Answer:
The p-value is;
d. 0.00131
Step-by-step explanation:
The given question parameters are;
Company A Company B
Sample size 80 60
Sample mean $16.75 $16.25
Population standard deviation σ₁ $1.00 σ₂ $0.95
Therefor, we have;
The p-value = 1 - 0.99869 (the area to the right of 3.01) = 0.00131
Answer: C) 7.5 feet
Step-by-step explanation:
1. You know that the triangles are similar. Therefore, to calculte the lenght of her puddle (which is identified in the figure as <em>l</em> ), you can set up the following proportions:
2. Now, you must solve for <em>l. </em>Then you obtain that the result is:
3. The answer is the option C.
