Answer:

C

Step-by-step explanation:

Count the number of sections.

... 12!

Now count the number of sections with a label of 5.

... 3!

So the probability of getting a 5 with one spin is \frac{3}{12} or 25%.

Now we can calculate the probability of getting a 5 with 150 spins.

P(5)=0.25*150

P(5)=37.5

The closest answer is 40.

Answer:

C) 40 times

Step-by-step explanation:

Out of the <em>12 parts, 3 of those are labeled</em> 5.

That means that there is a <em>3/12 = 1/4 chance</em> that you will land on it when you spin the spinner.

Out of 150 spins, if you get 5 on about 1/4 of them, about 150 * 1/4 = 37.5 ≈ <em>40 times</em> will yield 5.

PLEASE HELP ITS URGENT!!<br> Given: △ABC is isosceles; 1 ≅ 3<br> Prove: AB || CD
Dmitrij [34]

Answer:

AB ║ CD. (Proved)

Step-by-step explanation:

See the attached diagram of the triangle.

It is given that Δ ACD is an isosceles triangle.

Therefore, AC = AD and ∠ ACD = ∠ ADC, ⇒ ∠ 3 = ∠ 4 .......... (1)

Again, given that ∠ 1 = ∠ 3 ........... (2)

Now, from equations (1) and (2) we can write, ∠ 1 = ∠ 4

Now, AB and CD are two straight lines and AD is the transverse line and hence, ∠ 1 and ∠ 4 are alternate angles that are equal.

Therefore, AB and CD are parallel straight lines and AB ║ CD. (Proved)
