Answer: $m= -\frac{1}{26}$

(19,-16) = (x1,y1)

(-7-15) = (x2,y2)

Slope= $\frac{y2-y1}{x2-x1}$

= $\frac{-15-(-16)}{-7-19}$

= $\frac{-15+16}{-7-19}$

= $\frac{-15+16}{-26}$

= $-\frac{1}{26}$

The slope is 1/-26 so y+16=1/-26(x-19)

The diagram rerpesents responses to a survey that include statements p and q . Which statement is true?

BARSIC [14]

Answer:

C. The number of responces $p\vee q$ is also 46

Step-by-step explanation:

Note that:

$p\wedge q$ means both p and q must hold;
$p\vee q$ means either p or q must hold.

From the diagram,

the number of responses $p\wedge q$ is 46;
the number of responces $p\vee q$ is also 46;
the number of responces $p\setminus q$ is 0;
the number of responces which are neuther p nor q is 20.

So, you can state that the correct answer is C

Suppose that 5 cards are drawn from a well-shuffled deck of 52 cards. What is the probability that all 5 are not black?

lions [1.4K]

Here's the way I see it: 5 cards are drawn, one by one, without replacement. Half (or 26) of the original deck are black and half (26) are white.

P(5 are not black) = P(5 are red)

P(5 are not black) = P(first card is red) * P(second card is red) * P(third card is red)*P(fourth card is red)*P(fifth card is red) =

(26/52) * (25/51) * (24/50) * (23/49) * (22/48) = 0.025 (answer)

We start with 52 cards. We draw one, leaving 51 cards, 25 of which are red. And so on.

Please help! thanks!

Answer:

Step-by-step explanation:

Remember how absolute values turn everything inside of it into a positive number? Like |-4|=4 and |4|=4 as well.

Well, it works the same for equations.

When you have an absolute value equation like this, you have to split it into two parts.

The positive version

| d-3.5 | ≤ 1.5

and the negative version

|-(d-3.5)| ≤ 1.5

solve for the value of d in both equation.

<em>Remember that you have to flip the inequality sign when dividing or multiplying by a negative number</em>

I assume you know how to graph the inequality once you get the value for d.

d≤5 and d≥2

2 ≤ d ≤ 5

meaning d is between 2 and 5.
