LekaFEV [45]

The best choice is 'C'. If it's 1, 5, and 4, then ideally, in 100 draws, you would expect 10, 50, and 40 ... pretty close to Tyrell's actual experimental results.

Which of the following expressions are equivalent to -5/-7×-11/-6

USPshnik [31]

Answer:

Step-by-step explanation:

-5/-7×-11/-6

= (-5 * -11) / (-7*-6)

= 55 / 42.

A. = - (6/-11) = 6/11

-5/7 * 6/11 = -30/77.

B. - (-11/7) = 11/7

5/6 * 11/7

= 55/42.

Suppose KLMN ~ PQRS. Find the value of x.

arlik [135]

Complete question is attached.

Answer:

B) 8

Step-by-step explanation:

In this question, KLMN ~ PQRS. This means they are similar shapes.

From the image, we could denote that:

KL ~ PQ

LM ~ QR

Given that:

KL = 12

PQ = 30

QR = 20

LM = x

To find x, let's use tge expression:

$\frac{KL}{PQ} = \frac{LM}{QR}$

$= \frac{12}{30} = \frac{x}{20}$

Cross multiplying, we have:

12 * 20 = 30x

240 = 30x

To find x, let's divide both sides by 30.

$\frac{240}{30} = \frac{30x}{30}$

8 = x

x = 8

The correct option is option B.
