Survey 50 randomly selected seventh-grade students at each of the district’s middle schools. Then the correct option is A.
<h3>What is a sample?</h3>
A sample is a group of clearly specified components. The number of items in a finite sample is denoted by a curly bracket.
The athletic director of a large school district with about 1,500 seventh-grade students in five different middle schools wants to know which sport is most popular among seventh graders.
The survey method is the best to use will be
Random sampling is the method of selecting the subset from the set to make a statical inference.
Survey 50 randomly selected seventh-grade students at each of the district’s middle schools.
Thus, the correct option is A.

44/35 = 1 9/35
So, your answer is 1 9/35
Answer:
Step-by-step explanation:
5x - 1 = 4x + 3
x - 1 = 3
x = 4
5(4) - 1 + 4(4) + 3
20 - 1 + 16 + 3
19 + 16 + 3 = 35 + 3 = 38

Step-by-step explanation:
Answer:
104 degrees
Step-by-step explanation:
First let's start by finding Angle DGC. Since Angle FGD and DGC are a linear pair, Angle DGC = 180-90 = 90 degrees.
Next we need to find GDC
Angles in a triangle add up to 180 degrees therefore...
Angle GDC + DCG + DGC = 180
Plug in the values we found into the equation
Angle GDC + 37 + 90 = 180
Angle GDC + 127 = 180
Angle GDC = 53
Therefore Angle ADC = 53 + 51 = 104 degrees
Since ABCD is a parallelogram, then opposite angles are equal therefore...
Angle B = 104 degrees
