Answer:

- p ⇒ - q

Step-by-step explanation:

p : Drive over 65 miles

q : You get a speeding ticket.

So then we get the negations.

- p : You do not drive over 65 miles

- q : You don't get a speeding ticket.

So, we need to connect the sentences. For that we use ⇒.

⇒ : then.

So, the sentence, If you do not drive over 65 miles per hour, then you will not get a speeding ticket

Can be written as : -p ⇒ -q

Deacon wants to order DVDs. Each DVD costs $12.95, and he must pay a shipping and handling fee of $4.95 for the entire order. De
eduard

Answer:

12.95a + 4.95 ≤ 75

Step-by-step explanation:

Given:

Cost of each DVD = $12.95

Total shipping fee = $4.95

Total amount as gift card = $75

Find;

Inequality

Computation:

Assume;

Number of DVD he purchase = a

So,

Total amount as gift card ≥ (Cost of each DVD)(Number of DVD he purchase ) + Total shipping fee

75 ≥ (12.95)(a) + 4.95

12.95a + 4.95 ≤ 75

Find the slope of the line that passes through the pair of points (6, 7) and (9, 2). User: Find the slope of the line that passe
DaniilM [7]
If we have two points;
A(x₁,y₁)
B(x₂,y₂)

m=slope

m=(y₂-y₁) / (x₂-x₁)

Therefore:
(6,7)
(9,2)

m=(2-7) / (9-6)=-5/3.

Solution₁= the solpe of the line that passes through the poitns (6,7) and (9,2) is m=-5/3.

(17,9)
(5,29)

m=(29-9) / (5-17)=20/-12=-5/3

Solution ₂: the slope of the line that passes through the  parir of points (17,9) and (5,29) is m=-5/3

Therefore, both lines have the same slope.

11. Suppose you buy 1 ticket for $1 out of a lottery of 1,000 tickets where the prize for the one winning ticket is to be $500.
erastovalidia [21]

Answer:

-50 cents

Step-by-step explanation:

The "Winnings" random variable has values -1 and 499

The associated probabilities are P(-1)= 999/1000; P(499)=1/1000

-----------------------------

Expected Value = -1(999/1000) + 499(1/1000) = -500/1000 = -50 cents
