The house blueprint shows the bedroom is 4 in wide and its actual length is 12 yards wide. What is the scale for the blueprint?
malfutka [58]

Answer:

Step-by-step explanation:

The house blueprint shows the bedroom is 4 in wide and its actual length is 12 yards wide. This means that every 1 inch on the blue print represents 3 yards on the actual building. The scale is the ratio of the length of a side on the blueprint to the length of a corresponding side on the actual. Therefore, the scale for the blueprint is 3: 1

Therefore, the scale factor is 3

What are the degrees of freedom associated with the factor(s) in this study design?
miss Akunina [59]

Answer:

The question is unclear and incomplete.

Let me explain the degrees of freedom in statistics.

Step-by-step explanation:

Statistically, degrees of freedom which is denoted as DF is the number of independent values that can vary in an analysis without breaking any constraints. It can also be referred to as the number of independent values that a statistical analysis can estimate.

Degrees of freedom also define the probability distributions for the test statistics of various hypothesis tests.

The degree of freedom has the formula:

DF = N - 1 where N number of random variables

DF = (R - 1) x (C - 1) Where R is the number of data values and C is the number of groups

Answer:

x = 50°

Step-by-step explanation:

Step 1.

180° - 80° (because there are 180 degrees in a triangle) = 100°

Step 2.

100° ÷ 2 = 50° (because the two angles on the bottom are identical, as this is an isosceles triangle - which we know because the two sides on the left and right are both the same length, 7 units)

Step 3.

Answer: x = 50°

Answer:

B= 15 adults tickets

C= 35 student tickets

Step-by-step explanation:

x+y=50

solve for y

y=50-x

5x+3y=180

5x+3(50-x)=180

5x+150-3x=180

2x=30

x=15

y=50-15

y=35
