Answer:y=-4.6667

Step-by-step explanation:

Answer:  y= -4

Step-by-step explanation:

6y + 2 = 9y + 14      Subtract 2 from both sides

      -2             -2

6y = 9y + 12             Subtract 9y from both sides

-9y    -9y

-3y = 12      Divide both sides by -3

y= -4

Answer:

C

Step-by-step explanation:

We start by calculating the z-score of 27 minutes

Mathematically z-score = (x-mean)/SD

FROM the question, mean = 21 and SD = 2

so z-score = (27-21)/2 = 6/2 = 3

The probability we want to calculate is P(z > 3)

we proceed to the standard normal distribution table to get this

P(z > 3) = 0.0013499

Now seeing this, we want to calculate the number of days.

Since there are 180 days in a year and we have 4 years, the total number of days = 180 * 4 = 720 days

The number of days in which the school bus took more than 27 minutes will be ;

720 * 0.0013499 = 0.971928 which is approximately 1

On edmentum this is correct.

Answer:

The answer is 8.5

Step-by-step explanation:

50-46.10=3.9

you then divide 3.9 by 46.10 and you get 0.0845...

so you estimate and get your answer

The percent error in Wesley's estimate is 8.5% if the estimated total purchase is $50 and the actual total purchase is $46.10.

Percentage is a form of writing numbers as part of 100. The symbol used to denote percentage is '%'.

Percentage of a number can be calculated by dividing the number with the whole and then multiplying with 100.

Percentage is a dimensionless number because it has no measurement units.

The percent error can be calculated by the formula,

Percent error = [(Estimated value - Actual value)/ actual value] × 100

Estimated total purchase of groceries by Wesley = $50

Actual total purchase made by Wesley = $46.10

Percent error = [(50 - 46.10) / 46.10] × 100

                      = (3.9 / 46.10) × 100

                      = 0.0846 × 100

                      = 8.46%

                      ≈ 8.5%

Hence the percent error for the estimation of total purchase of groceries by Wesley is 8.5%.

Step-by-step explanation & answer:

When a dilation in the coordinate plane has the origin as the center of dilation, we can find points on the dilated image by multiplying the x and y coordinates of the original figure by the scale factor.

For example, if the scale factor is "k", the algebraic representation of the dilation is

(x, y) → (kx, ky)

For enlargements, k > 1 and for reductions, k < 1.

Hope this is what you needed:)

The after the dilation by scale factor of 3, coordinates the point P(x, y) will become P'(3x, 3y).

A dilation is an enlargement or reduction of a figure about a center of dilation by a specified scale factor [k].

Given is a algebraic rule for a dilation with a scale factor of 3.

Suppose that we have a point P(x, y) which is dilated by the

scale factor of 3. Now, after dilation of the coordinate, the final coordinates of that point P(x, y) will become P'(3x, 3y). If the scale factor would have been less than one the point will contract.

Therefore, the after the dilation by scale factor of 3, coordinates the point P(x, y) will become P'(3x, 3y).

Simplifying

75 = 2x + -1

Reorder the terms:

75 = -1 + 2x

Solving

75 = -1 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

75 + -2x = -1 + 2x + -2x

Combine like terms: 2x + -2x = 0

75 + -2x = -1 + 0

75 + -2x = -1

Add '-75' to each side of the equation.

75 + -75 + -2x = -1 + -75

Combine like terms: 75 + -75 = 0

0 + -2x = -1 + -75

-2x = -1 + -75

Combine like terms: -1 + -75 = -76

-2x = -76

Divide each side by '-2'.

x = 38

Answer: The "rise over run" is equivalent to 1/3

Step-by-step explanation:

Since the m variable in the equation is 3, the line is going to be wider, there for it will go up 1 and 3 to the right with each point on the line, therefore the answer is B.

The requried slope of the line is 3, which is a positive number. Therefore, the line has a positive slope, and option D is true.

The equation is the relationship between variables and represented as y = ax + b.

Here,
A.

The y-intercept is -7.
The equation y = 3x - 7 is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. Therefore, the y-intercept of this line is -7, not 7, as given in option A.

B.
The "rise over run" is equivalent to 3. Option B is not correct.

C.
point (1, 4) lies on the line.

To check whether the point (1, 4) lies on the line, we can substitute x = 1 and y = 4 into the equation y = 3x - 7 and see if the equation is true:

y = 3x - 7

4 = 3(1) - 7

4 = -4

Since the equation is not true, the point (1, 4) does not lie on the line, and option C is false.

D.
The line has a positive slope.

As we determined earlier, the slope of the line is 3, which is a positive number. Therefore, the line has a positive slope, and option D is true.
