Answer:

Number of trials are 250.

Step-by-step explanation:

A researcher finds 15% of all commuters in a metropolitan area take the train to work.

The researcher polls 250 people in the area to ask them whether they take the train to work or not.

We have tell the number of trials for this binomial experiment.

Researcher will do 250 trials to confirm whether they take the train work and this irrespective of their response.

Answers

inpus 0.8 for y
4x+8(0.8)=40
4x+6.4=40
minus 6.4 both sides
4x=33.6
divie both sides by 5
x=8.4

x=8.4 when y=0.8
4x+8y=40
4x + (8x.8)= 40
4x + 6.4 = 40 
4x = 33.6
x = 8.4

Draw and label line AB. Draw point C on it

Answers

To draw line AB with point C on it, draw a line segment AB by using a compass draw one point on the line and label the dot C.

Draw a line segment and label its endpoints with the letters A and B. You are then asked to draw a point on the line segment and label it with the letter C.

Here is a step-by-step guide on how to draw point C on line AB:

1. Draw a straight line segment using a ruler.

2. Label the endpoints of the line segment with the letters A and B.

3. Place the compass point at point A and draw an arc that intersects line AB.

4. Without changing the compass radius, place the compass point at point B and draw an arc that intersects the first arc.

5. Label the point of intersection point C.

The length of a rectangle is 3 inches greater than the width. A. Write a polynomial that represents the area of the rectangle.
B. Find the area of the rectangle when the width is 4 inches.

Answers

Answer:

A - x (x+3) = Area of the rectangle

B- 28 inches squared

Step-by-step explanation:

B- using the formula from A

x = 4

x + 3 = 4 +3 = 7

4 times 7 is 28

Answer: 28ins²

Step-by-step explanation:

From the question, let the width of the rectangle = xins.

Therefore, the breadth                                            = ( x + 3 )ins.

(A) The area of the rectangle which is L x B          = x( x+ 3 )

                                                                              = (x² + 3x)ins² . In polynomial.

(B) The area of the rectangle if the width is 4ins, that is if x = 4ins.To find the area, we substitute for x in the area above

                                                                             = 4² + 3 x 4

                                                                             = 16 + 12

                                                                             = 28ins²

Answers

This is an EXPONENT. 

To do this all we need to do is multiply the base by itself how many times the power says.

(-6)² = (-6) × (-6) = 36

Recall that any negative number times another negative number is positive so that is why this would be positive.  

So, (-6)² = 36

Hope I helped ya!! 
(-6) x (-6) = **36**
