Answer:

B.) Transitive Property of Congruency; If parallel lines have a transversal, then alternative interior angles are congruent.

Step-by-step explanation:

Alternate interior angles are the two angles that are inbetween the parallel lines but are on opposite sides of the transversal. Angles 4 and 5 are alternate interior, and therefore, they are congruent.

Karen karlin bought some large frames for $15 each and some small frames for $8 each at a closeout sale. if she bought 22 frames

BaLLatris [955]

small frames ($8): s

large frames ($15): L

Cost: 8s + 15L = 239 ⇒ 1(8s + 15L = 239) ⇒ 8s + 15L = 239

Quantity: s + L = 22 ⇒ -8( s + L = 22) ⇒ <u> -8s -8 L = -176 </u>

7L = 63

L = 9

Quantity: s + L = 22 ⇒ s + (9) = 22 ⇒ s = 13

Answer: 13 small frames, 9 Large frames

What is the area of this figure?

matrenka [14]

There is 2 figure here, a triangle and a parallelogram.
Area of parallelogram=base * height
A=9 * 5
A=45m²
Area of triangle= $\frac{1}{2}$ (base * height)
A= $\frac{1}{2}$ (9*8)
A= $\frac{1}{2}$ 72
A=36m²
36+45=81m²
The area of this figure is 81m²

Answer:

Mean = 10

Variance = 30.89

Standard Deviation = 5.56

Step-by-step explanation:

Find the Mean, Variance and Standard deviation

6, 14, 8, 2, 11, 7, 12, 4, 18, 18

Step 1

We rearrange the data and find the Mean

2, 4, 6, 7, 8, 11, 12, 14, 18, 18

Mean = Sum of values/Number of values

= 2 + 4+ 6+ 7+ 8 + 11 + 12 + 14 + 18 +18/10

= 100/10

= 10

Step 2

We find the variance of this sample days ma

Variance = (x - Mean)²/n - 1

n = 10

Hence,

=( (2 - 10)² +(4 - 10)²+ (6 - 10)²+ (7 - 10)² + (8 - 10)² + (11 - 10)² + (12 - 10)² + (14 - 10)² + (18 - 10)² +(18 - 10)²) /10 -1

= ( 64 + 36 + 16 + 9 + 4 + 1 + 4 + 16 + 64 +64)/9

= 278/9

= 30.88888889

Approximately = 30.89

Step 3

Standard Deviation = √Variance

= √30.89

= 5.5578772926

Approximately = 5.56
