Answer:

Step-by-step explanation:

2a + 4b = 12c

4b = 12c - 2a

b = 3c - 1/2a

Step-by-step explanation:

If Two signs that scores are significantly different then (a) the error bars of group will not overlap

Error bars are graphical representations of data variability that are used to indicate the error or uncertainty in a reported measurement on graphs.

The estimated error in a measurement is indicated by error bars. In other words, an error bar represents the degree of uncertainty in a value.

When the standard deviation error bars overlap significantly, it is an indication that the difference is not statistically significant. To reach a conclusion, you must conduct a statistical test.

When the standard deviation error bars overlap even less, it indicates that the difference is unlikely to be statistically significant.

For significantly different group , we also have p-value greater than 0.05

So, Option (b) is incorrect.

Hence, (a) The error bars of the groups will not overlap is correct

Answer: Sale price: $254.15 , Discount: $44.85

Step-by-step explanation:

15% off indicates that the stereo will now cost 85% of what it did originally:

$299(100% – 15%) = $299(85%)

Decimalizing the percentage results in = $299(0.85) = $254.15

Discount= $299 - $254.15 = 44.85

If according to the American Veterinary Medicine Association, 72% of households in Wyoming owned a pet in 2018. There were 278,595 households in Wyoming in 2018. The number of those households that owned a pet is:  200,588.

We would be making use of the given data to find the number of household that owned a pet.

Using this formula

Number of household with pet = Percentage of household × Number of household

Let plug in the formula

Number of household with pet = 72% × 278,595

Number of household with pet = 200,588 household

Therefore the Number of household with pet  is 200,588.

The Range of the length of a rectangle having fixed width and area increasing linearly is  = {y ∈ R : c ≠ 0 or y ≠ 0}, and Domain = All real numbers,

An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel, opposite sides. Since a rectangle is a two-dimensional form, it has two dimensions: length and width. The rectangle's longer side is its length, while its shorter side is its breadth.

Given:

The width of the rectangle is fixed, and the length is changing.

The line is formed when connected through the graph.

The area of the rectangle = [tex]length\times width[/tex]

So when the width is fixed, the area would increase linearly and directly proportional to length.

Calculate the range of function y = cx,

y = area as shown in the graph, x is the length, and width is constant c.

Range = {y ∈ R : c ≠ 0 or y ≠ 0}

Calculate the domain,

It can be any real number, as the area can't be negative.

Domain = All real numbers.

Step-by-step explanation:

The coordinates of P and Q are

PQ have equal slope with BC so they are parallel

The coordinates of P and Q is found using the midpoint formula

The formula is of the form

X= (x₂ + x₁)/2

Y = (y₂ + y₁)/2

solving for P (X, Y) Using points A(2, -1), B(-3, 4)

(X, Y) = ((2 + -3)/2, (-1 + 4)/2)

= (-1/2, 3/2)

solving for Q (X, Y) points A(2, -1), C(-5,-7)

(X, Y) = ((2 + -5)/2, (-1 + -7)/2)

= (-3/2, -4)

Parallel lines have equal slopes

Using BC = (4 - -7) / (-3 - -5) = 11/2
