Answer:

the number line is attached below

Step-by-step explanation:

add using the number line. ​ −3+11

Use the number line to add the numbers

Start at -3 on number line. then to add 11, move 11 units to the right

From -3, move 11 units the right. we reach at 8 on the number line

So -3+11 is 8

The number line is attached below

Answer:

-3 + 11 = 8

Step-by-step explanation:

Just plot 8 on the number line.

A rectangular gift box is 9inches inches wide, 12 inches long and 5 inches tall. How much wrapping paper is needed to cover the box exactly

Answers

Answer:

You will 426 \:in^2 wrapping paper to cover the box.

Step-by-step explanation:

To find how much wrapping paper you will need to cover the box, you will have to find the surface area.

The surface area is the amount of area around the outside of an object.

The outside surface area of a box is given by

                                S=2(h \cdot W) + 2(h\cdot L) + 2(W \cdot L)

where h is the height, W is the width, and L is the length of the box.

From the information given we know that the height is 5 inches, the width is 9 inches, and the length is 12 inches.

Applying the above formula we get that

S=2(5 \cdot 9) + 2(5 \cdot 12) + 2(9 \cdot 12) \nS=2\cdot \:45+2\cdot \:60+2\cdot \:108\nS=90+120+216\nS=426 \:in^2

You will 426 \:in^2 wrapping paper to cover the box.

AC is a straight segment as shown in the diagram below. If the distance between points A and C is 67 miles, determine the distance between points A and B.

Answers

Final answer:

Without additional information such as the location of point B along line segment AC, or the distances from B to either A or C, it is impossible to determine the distance between points A and B based on the provided details.

Explanation:

The problem here is lacking some necessary information to accurately determine the distance between points A and B. Given that AC is a straight line segment and the distance between A and C is 67 miles, we still need further details to conclude the distance from A to point B, such as knowing the position of point B along segment AC, or the distances from B to either A or C. Without these specifics, it's impossible to determine the distance between points A and B based upon the given information.

How many randomly selected employers must we contact in order to create an estimate in which we are 95​% confident with a margin of error of 9​%? ​b) Suppose we want to reduce the margin of error to 4​%. What sample size will​ suffice? ​c) Why might it not be worth the effort to try to get an interval with a margin of error of 1​%?

Answers

Answer:

a)n=543

b)n=1509

c)n=13573

Step-by-step explanation:

a)

c=98%,

E=0.05

Margin Error E=Zα/2√p(1-p)/n

but n=((Zα/2)/n)²×p(1-p)

where the confidence level is 1-α=0.98

cross multiply

Zα/2=2.33

where p=0.5

input the values

n=(2.33/0.55)²×0.5(1-0.5)=543

n=0.33

b) E=0.33

E=Zα/2√p(1-p)/n

n=((Zα/2)/n)²×p(1-p)

1-α=0.01 confidence level

n=(2.33/0.33)²×0.5(1-0.5)=1504

n=1504

c) E=Zα/2√p(1-p)/n

n=((Zα/2)/n)²×p(1-p)

1-α=0.98

cross multiply

Zα/2=2.33

p=0.5

n=(2.33/0.01)²×0.5(1-0.5)=13573

n=13573
