Answers

Answer:

Line 1 and Line 2: Neither -- slopes are not same (one is negative one is positive)

Line 1 and Line 3: Perpendicular -- Line 3's slope is the negative reciprocal of Line 1's

Line 2 and Line 3: Neither -- different slopes

Step-by-step explanation:

Lines are parallel if they have the same slope but different y-intercept.

Lines are perpendicular if the slopes are negative reciprocals.

Alice earned $12 per hour. What equation shows the relationship between her weekly salary (w), hours per week (h), and rate per hour (r).

Answers

12h=w

because the 12 is the r and you multiply it by h to get w

R multiplied by h equals w because the amount of hours times the amount of money per hour would equal the total per week

Step-by-step explanation:

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Right triangle XYZ, with vertex Y at (-3, 0), is rotated clockwise 180° about the origin. Which of the following rotations is equivalent to 180° clockwise rotation about the origin? clockwise 360° counterclockwise 180° counterclockwise 360° clockwise 270°

Answers

Answer:

the rule for rotation 180 degrees clockwise around the origin is:

(x,y) --------> (-x,-y)

(-3,0) --------> (-(-3),0)

(-3,0) --------> (3,0)

rotation counterclockwise 180 degrees is the same as rotation 180 degrees clock wise:

The length of a rectangle is 3ft more than twice the width, and the area of the rectangle is 54ft^2. Find the dimensions of the rectangle.

Answers

Answer: Let length = 2x + 3

Let width = x

Area = 54 ft2

length × width = Area

x(2x + 3) = 54

2x2 + 3x = 54

2x2 + 3x - 54 = 0

(2x - 9)(x + 6) = 0

x = 9/2 and x = -6

x = 4.5 and x = -6

We accept x = 4.5 because length cannot be a negative value. Substituting this value into the dimensions:

width = 4.5 ft

length = 2(4.5) + 3 = 9 + 3 = 12 ft

Step-by-step explanation:

Let wedth = x
Length = 2x+3
Area = 54
Area = l X b
54= (2x + 3) X x
54 = 2 x² + 3x
The equation will be:
2 x² + 3x - 54
2 x² + 12x -9x - 54
2x (x+6) -9(x + 6)
(2x-9) (x+6)
We will use (2x-9)
2x-9= 0
2x = 9
x = 9/2
x = 4.5

Width = 4.5
Length = (2x +3)
Length = (2X 4.5 + 3)
Length = 9.0 + 3 = 12

The Bradenton Post polled 1,356 adults in the city to determine whether they wet their toothbrush before they put toothpaste on it. Of the respondents, 54% said they wet it first. Suppose 68% of all adults actually wet their toothbrush first. What are the mean and standard deviation of the sampling distribution?

Answers

Answer:

deviation = -95.50147493 mean = 61

Step-by-step explanation:

54% wet there brushes first

suppose 68% wet there brushes what is the mean

mean: a mean is where you add both numbers together to get a total then divide by how many numbers you added for now we wont need the amount of people we just need the percentages for this

54 + 68 = 122

we added to numbers so well divide by 2

122 divided by 2 or 122/2 is equal to 61

61 is our mean

standard deviation : this is were you take the known average 1356 adults and subtract the mean

1356- 61 = 1295 then divide by 1356 and times by 100

if the number is positive then the mean is higher than expected but luckily its a negative so its -95.50147493
