arlik [135]

Answer:

The area is 6.25 times greater.

Step-by-step explanation:

Each side of the triangle of the dilated triangle will be 2.5 times the length of the original sides.

The area will increase to 2.5^2 = 6.25 times.

Use a graphing calculator to sketch the graph of the quadratic equation and then give the coordinates for the x-intercepts (if t

Nataly [62]

Answer:

Option D.

Step-by-step explanation:

The given quadratic equation is

$y=x^2+7x+10$

We need to draw the graph of given equation by using graphing calculator as shown below.

From the graph it is clear that the parabola intersect the x-axis at points (-2,0) and (-5,0). So, the x-intercepts are (-2,0) and (-5,0).

Therefore, the correct option is D.

if the first two statements are true, is the third statement true? 1. all dogs like walks. 2. bandit doesn't like walks. 3. band

Strike441 [17]

If the first two statements are true, then the third statement:

"Bandit is not a dog"

Is true.

<h3>if the first two statements are true, is the third statement true?</h3>

The first statement is:

P = "All dogs like walks"

We assume that this is true, so, if X is a dog, X likes walks.

The second statement is:

Q = "Bandit doesn't like walks"

From this, we only can conclude that Bandit doesn't like walks.

And all dogs like walks, so if Bandit were a dog, he would like walks, but because he does not like walks, we can conclude that Bandit is not a dog.

From that, the third statement:

K = "Bandit is not a dog"

Is true.

So we write that as a conditional statement:

If P and Q ⇒ K

<em>"if all dogs like walks, and Bandit doesn't like walks, then bandit is not a dog".</em>

A shipment of 12 microwave ovens contains 3 defective units. A vending company has ordered 4 of these units, and because all are

pishuonlain [190]

P(defective) = 3/12 = 1/4
P(good) = 1 - 1/4 = 3/4
$P(2\ good)=4C2\times0.75^{2}\times0.25^{2}=0.211$
$P(3\ good)=4C3\times0.75^{3}\times0.25=0.422$
$P(4\ good)=0.75^{4}=0.316$
The probability that at least 2 units are good is given by:
P(2 good) + P(3 good) + P(4 good) = 0.211 + 0.422 + 0.316 = 0.949.
