Answer:

z = 56 degrees

Step-by-step explanation:

y = 124 because y is adjacent to 124 degrees

y + z = 180

180 - 124 = 56

Best Answer: A. Mode
B. Median
C. Mean

the other two are not measures of central tendency.
Data:
4+9/12, 5+3/12, 5+4/12,5+7/12,5+3/12, 5+9/12,6+0/12, 5+4/12,6+0/12, 6+1/12,5+7/12, 5+5/12, 4+5/12

4.4167, 4.75, 5.25{2}, 5.3333{2}, 5.4167, 5.5833{2}, 5.75, 6{2}, 6.0833

n= 13; Σx= 70.75; Σx²= 387.8403; Σx³= 2140.408; Σx^4= 11886.2257
σ= 0.4638; σn-1= 0.4828; Variance=σ²= 0.2152; (σn-1)²= 0.2331
Mean(μ)= 5.4423; range= 1.6667; mid-range= 5.25; median= 5.4167; No Mode Probably right skewed.
Five number summary: Q0= 4.4167, Q1= 5.25, Q2= 5.4167, Q3= 5.875, Q4= 6.0833, IQR= 4.875

8 = x divided by 12.8

GarryVolchara [31]

8 = x / 12.8
102.4 = x

Therefore x = 102.4

Kyle determines that y ≥ − 8/3 x-4 is shown on the graph. Is Kyle correct? If not, determine the correct inequality.

Troyanec [42]

Answer:

C) No, Kyle is incorrect. The correct inequality is $\displaystyle y > -\frac{8}{3}x - 4$

Step-by-step explanation:

This graph has a dashed line, so it would be either less than or greater than. The only way to find out is to use the zero-interval test [test point (0, 0)] to ensure whether we share the opposite portion [the portion that does not contain the origin] or the portion that DOES contain the origin. This is where we verify the inequality as false or true:

Greater than

$\displaystyle 0 > -\frac{8}{3} - 4 → 0 > -4$ ☑

Less than

$\displaystyle 0 < -\frac{8}{3} - 4 → 0 ≮ -4$

This graph is shaded in the portion of the origin, so we choose the greater than inequality statement.

I am joyous to assist you anytime.

The length of a rectangle is three times its width.

BartSMP [9]

Answer:

perimeter:- 8x

Step-by-step explanation:

since,

length= 3(width)

length= 3x

and, perimeter= 2(l + b)

= 2(3x + x)

= 2(4x)

perimeter = 8x
