Answer:

$a = 7, LN = 105$

Step-by-step explanation:

$LM = 8a$

$\textrm{LM also equals 56}$

Solve for a

$8a = 56 \rightarrow a =7$

Given that a = 7, solve for MN

$MN = 7a$

$MN = 7(7) \rightarrow 49$

In order to find LN, add 49 and 56 together

$49 + 56 = 105$

$LN = 105$

Ganezh [65]

Answer:

Step-by-step explanation:

Spinner A

Probability of red = 0.5,
Probability of blue = 0.5

Spinner B

Probability of red = 0.6,
Probability of blue = 0.4

Probability of both A and B land on red:

0.5*0.6= 0.3

Number of attempts to get outcome of 84 red on both spinners is:

84/0.3= 260

Probability of both spinners land on blue:

0.5*0.4= 0.2

Estimated number of both spinners land on blue:

260*0.2= 52
