Because the correct inch is 4 1/4 while the equation 3 1/4 x 2 plus 1/2 is wrong :)
Answer:
The first one: 5x^3 -5x^2 +2x -2 + 6/x+1
Step-by-step explanation:
Answer:
y = 2x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
here m = 2 and b = - 4
y = 2x - 4 ← equation of line
The teacher should sample a proportional number of students in each type of dance class so that it possess all qualities of a good sample.
Firstly, the sample should be representative of the population. The teacher's goal is to determine the favorite type of dance class for students. Thus, sample should also consist of students only. This rules out option four. Sample cannot consist of teachers.
Secondly, the sample should be large enough to draw meaningful conclusions from it. This rules out option three. Sampling one student in each type of dance class will not give reliable results.
Third, the sample should be proportional. It will give truly accurate results id each unit or group of the population is fairly represented in the sample. Therefore, option two i.e., sampling a proportional number of students in each type of dance class is the best choice.

Step-by-step explanation: 100%
Answer:
156
Step-by-step explanation:
Using PEMDAS: We do the paranthese first:
7 * 22 + (8-2) / 3.
7 * 22 + 6 / 3.
Multiply / Divide:
154 + 6 / 3
154 + 2
156
You multiply 7 and 22 than add (8-2) than divide 3 than you will get 156
