For dilation's, you can ignore any negative signs.

An expansion would be a number greater than 1.

The correct answers would be a and b

The numbers double: 3 x 2 = 6, 5 x 2 = 10, so the scale factor is 2.

Draw a Hasse diagram of the partial order << of the set {2,3,4,6,8,9,10,12} where a << b iff b is divisible by a.

Ray Of Light [21]

Step-by-step explanation:

Consider the provided set {2,3,4,6,8,9,10,12}

Let the set is A.

$A={(2 \prec 4), (2 \prec 6), (2 \prec 8), (2 \prec 10), (2 \prec 12), (3 \prec 6), (3 \prec 9), (4 \prec 8), (4 \prec 12), (6 \prec 12)}$

Hence the required Hasse diagram is shown in figure 1:

In the Hasse diagram 2 and 3 are on the same level as they are not related.

The next numbers are 4, 6, 9, and 10. 4, 6 and 10 are divisible by both 2. 6 and 9 are divisible by 3. Then 8 and 12 are divisible by 4 also 12 is divisible by 6.

Hence, the required diagram of the partial order of the set {2,3,4,6,8,9,10,12} is shown in figure 1.

Four microprocessors are randomly selected from a lot of 100

ira [324]

Answer:

Step-by-step explanation:

From the set of 100 with 10 defective microprocessors, the probability of picking a defective one is;

10/100 = 1/10

From the set of 99 remaining and 9 defective microprocessors, the probability of picking a defective one is;

9/99 = 1/11

From the set of 98 remaining and 8 defective microprocessors, the probability of picking a defective one is;

8/98 = 4/49

From the set of 97 remaining and 7 defective microprocessors, the probability of picking a defective one is;

7/97

Adding all 4 probabilities together, we get;

1/10 + 1/11 + 4/49 + 7/97 = 0.345 or 34.5%

Last week Len spent $18 to bowl four games. This week he spent $27 to bowl six games. Len owns his bowling ball and shoes so he

pashok25 [27]

Len would pay 50 cents for each game he bowls because 4 cant go equally into 18 but the closest to that it can go is 16 so if you and 50 cents four times because he played four games, it would be 50 cents for each game he used the shoes. Hope this helped :)

How do you do this question?

Molodets [167]

Answer:

C. y₂ = (1 + (t/n))²

Step-by-step explanation:

yₙ₊₁ = yₙ + Δt F(tₙ, yₙ)

yₙ₊₁ = yₙ + Δt yₙ

yₙ₊₁ = yₙ + (t/n) yₙ

When n=0:

y₁ = y₀ + (t/n) y₀

y₁ = 1 + (t/n)

When n=1:

y₂ = y₁ + (t/n) y₁

y₂ = 1 + (t/n) + (t/n) (1 + (t/n))

y₂ = 1 + (t/n) + (t/n) + (t/n)²

y₂ = 1 + 2(t/n) + (t/n)²

y₂ = (1 + (t/n))²
