For your own safety, the bank representative says that the following characteristics of PIN numbers are prohibited:________. 1)

Natali [406]

Answer:

Total = N(1) +N(2)+N(3) = 10+14+200 = 224 sequences

224 sequences would NOT be permitted.

Step-by-step explanation:

1) all four digits identical

Number of possible PIN with all four digits identical N(1) = 1×1×1×10 = 10 possible PIN

2) sequence of consecutive ascending or descending digits N(2) = 14

Only Ascending starting with 0,1,2 = 3

only descending for 7,8,9 = 3

and both for 3,4,5,6 = (2×4)

Total = 3+3+(2×4) = 14

3) any sequence starting with 19 or 20 (birth years

N(3) = 2 × 1×1×10×10 = 2×100 = 200

N(3) = 200

(Note : 100 possible ways for each of 19 or 20s)

Total = N(1) +N(2)+N(3) = 10+14+200 = 224

224 sequences would NOT be permitted.

Galina is finding the area of triangle RST. To do so, she follows the steps in the table.

vladimir1956 [14]

1 step: to draw a rectangle around triangle RST, you should

draw points A(-1,-1), B(-1,3) and C(2,3);
connect points A, B, C and T consecutively.

2 step: rectangle ABCT has length AB=4 units and width BC=3 units. Then

$A_{ABCT}=4\cdot 3=12$ sq. un.

3 step:

$A_{\triangle ART}=\dfrac{1}{2}AR\cdot AT=\dfrac{1}{2}\cdot 2\cdot 3=3$ sq. un.

$A_{\triangle BRS}=\dfrac{1}{2}BR\cdot BS=\dfrac{1}{2}\cdot 2\cdot 2=2$ sq. un.

$A_{\triangle SCT}=\dfrac{1}{2}CS\cdot CT=\dfrac{1}{2}\cdot 1\cdot 4=2$ sq. un.

4 step:

$A_{\triangle RST}=A_{ABCT}-A_{\triangle ART}-A_{\triangle BRS}-A_{\triangle SCT}=12-3-2-2=5$ sq. un.

Answer: in step two you write dimensions of rectangle ABCT: length 4 units and width 3 units. Correct choice is B.

PLS Help im sooo stuck on this question pls help and show your work and please dont put a nonsense answer

Snowcat [4.5K]

XY = xZ

85b + 83 = 91b - 283

Subtract 85b from both sides:

83 = 6b - 283

Add 283 to both sides:

6b = 366

Divide both sides by 6:

B = 61

Now replace b with 61 and solve for the length:

85(61) + 83

5185 + 83 = 5268

The length is 5,268
