Answer:
If Andrea plays eight games at the arcade and wins 20 tickets per game then 8 x 20= 160.
If Andrea plays nine games at the arcade and wins 20 tickets per game then 9×20 = 180.
A= 9 games
Step-by-step explanation:
Answer: The y intercept is -7 or (0,-7)
Step-by-step explanation:
First convert the equation into slope intercept form .
y - 3 = -2(x + 5) Multiply on the right side
y -3 = -2x - 10 Add 3 to both sides
+3 +3
y = -2x - 7
In this case the y intercept is -7 and it is when x is zero.
Answer:
C. The normal distribution can be used because the original population has a normal distribution.
Step-by-step explanation:
When the original population has a normal distribution, we can use the normal distribution to solve the exercise.
In this problem, we have that:
The original population are the adult females.
The problem states that:
The overhead reach distances of adult females are normally distributed with a mean of 202.5 cm and a standard deviation of
7.8 cm.
So the correct answer is
C. The normal distribution can be used because the original population has a normal distribution.
<u>Explanation</u><u>:</u>
From the given figure ,
AB || CD
PQ is a transversal
Given angles are 50° and 130°
50° and x are linear pair
⇛ 50°+x = 180°
⇛ x = 180°-50°
⇛ x = 130°
Therefore, "x" = 130°
and
130° and y are vertically opposite angles which are equal.
⇛ "y" = 130°
Therefore, y = 130°
<u>Additional</u><u> </u><u>comment</u><u>:</u><u>-</u>
- If two parallel lines Intersected by a transversal then
- Corresponding angles are equal.
- Vertically Opposite angles are equal.
- The sum of two adjacent angles is equal to 180° then they are called Linear Pair.
