M<3 is (3x + 4) and m<5 is (2x +11)
butalik [34]

Answer:

Part 1) Option C. Same side interior angles

Part 2) Option A. (3x+4)+(2x+11)=180\°

Part 3) Option B. m

Step-by-step explanation:

Part 1) we know that

If p and q are parallel

then

m<3 and m<5 are consecutive interior angles or Same side interior angles

and

m

Part 2) we know that

m -----> by consecutive interior angles (supplementary angles)

we have that

m

m

so

substitute

(3x+4)+(2x+11)=180\°

Part 3) Find the measure of angle 5

we know that

(3x+4)+(2x+11)=180\°

Solve for x

5x+15\°=180\°

5x=180\°-15\°

x=165\°/5\°=33\°

m

substitute the value of x

m

A graph represents the feasible region for the system: y is less than or equal to 2x, x + y is greater than or equal to 45, and
atroni [7]
Notation. x  y means x is less than or equal to y. x y means x is greater than or equal to y. x < y means x is less than y. x > y means x is greater than y. The last two inequalities are called strict inequalities. Our focus will be on the nonstrict inequalities. Algebra of Inequalities Suppose x + 3 < 8. Addition works like for equations: x + 6 < 11 (added 3 to each side). Subtraction works like for equations: x + 2 < 7 (subtracted 4 from each side). Multiplication and division by positive numbers work like for equations: 2x + 12 < 22 =) x + 6 < 11 (each side is divided by 2 or multiplied by 1 2 ). 59 60 4. LINEAR PROGRAMMING Multiplication and division by negative numbers changes the direction of the inequality sign: 2x + 12 < 22 =) x 6 > 11 (each side is divided by -2 or multiplied by 1 2 ). Example. For 3x 4y and 24 there are 3 possibilities: 3x 4y = 24 3x 4y < 24 3x 4y > 24 4y = 3x + 24 4y < 3x + 24 4y > 3x + 24 y = 3 4x 6 y > 3 4x 6 y < 3 4x 6 The three solution sets above are disjoint (do not intersect or overlap), and their graphs fill up the plane. We are familiar with the graph of the linear equation. The graph of one inequality is all the points on one side of the line, the graph of the other all the points on the other side of the line. To determine which side for an inequality, choose a test point not on the line (such as (0, 0) if the line does not pass through the origin). Substitute this point into the linear inequality. For a true statement, the solution region is the side of the line that the test point is on; for a false statement, it is the other side.

Nuetrik [128]

Answer:5/18=.2777777777777

Step-by-step explanation:

.27777 (7 repeating)

100x=27.7777

10x=   2.7777

Subtract

90x=25

x=25/90=5/18

Check

5/18=.2777777777777

Hope that helps.

Determine whether the following is an example of a sampling error or a non-sampling error. 12% of all people are left handed. A
const2013 [10]

Answer:

Sampling Error

Step-by-step explanation:

When the researcher randomly selected 200 people, he is creating an sample or subset from the population, that would be all the people in the earth. The error obtained was product of the fact that the analysis he made was estimated from the sample and not the whole population. There is no other mentioned factor that could cause an error, so the answer would be a sampling Error.
