Answer:
u
Step-by-step explanation:
Solution:-
- Claim : pizza shop deliver in 30 minutes or less or it is free.
- Alternate : People who live in on opposite side of town believe it will take the pizza shop longer than 30 minutes to make and deliver the pizza.
- Sample size taken n = 50 > 30
- The sample mean = 32 mins
- The appropriate symbol for sample mean used in test statistics is (u).
Answer:
(0, -3) and (2, 1)
Step-by-step explanation:
There are 5 points marked on the graph: (±2, 1), (±1, -2) and (0, -3). These are solutions to the equation describing the function:
... y = x² - 3
Apparently, you are being asked to report the coordinates of any two of these points.

<em>Comment on the problem</em>
The wording "solutions to the function" is a bit odd. An equation has solutions—values of the variables that make it be true. A function is a relationship between values, a definition. There is nothing to solve.
In the above we have assumed the intent is to find (x, y) pairs that match the function definition. Sometimes, we're interested in values of x that make y be zero. (x, y) = (±√3, 0) It isn't obvious what the intent of this question is.
Part A:
Given that Rachel is planning a wedding for 100 to 250 people, the <span>inequality in terms of p people that describes how many people Rachel plans to invite is given by:
100 ≤ p ≤ 250
Part B:
Given that the </span>caterer charges $20 per person, plus a flat fee of $200,<span> the </span><span>inequality that shows how much the caterer will charge in terms of p is given by:
20(100) + 200 ≤ 20p + 200 ≤ 20(250) + 200
</span>
Part C:
<span>The range of catering fees (C) that Rachel is considering is given by:
</span><span>20(100) + 200 ≤ 20p + 200 ≤ 20(250) + 200
2000 + 200 ≤ C ≤ 5000 + 200
2200 ≤ C ≤ 5200
Therefore, the range of catering fees Racheal is considering is from $2,200 to $5,200

Answer:
24°
Step-by-step explanation:
(4y-4)+(180-52)+3y = 180°
4y-4+128+3y = 180
7y+124 = 180
7y = 56
y = 8
SO ∠x = 3y
∠x = 3(8)
∠x = 24
Answer:
1.2, 1.6, 2.0
Step-by-step explanation:
Pythagorean theorem
A^2 +b^2=c2
1.2^2+1.6^2=2^2
1.44 + 2.56=4
4=4
Since equation works (4=4), it is a right triangle.
