Rai compares to cable plans from different companies which equation gives the correct value of and the number of my switch plans a and b cost the same

Step-by-step explanation:

Option  D is correct.

Step-by-step explanation:

Here, m represents the months.

We have to find the equation for which Plans A and B cost the same.

In Plan A:

No initial fees.

$75 per month.

For 1 month = $ 75

then;

for m month =$ 75 m

⇒Total cost for plan A =  75m

In Plan B:

$50 per month for first 12 month.

For 1 month = $ 50

for 12 months = 50(12)

Similarly for:

$125 per month for each additional month after that.

For additional month (m-12) = 125(m-12)

then

Total cost for plan B = 50(12)+125(m-12)

Since, Plans A and B cost the same.

⇒

Therefore, an equation gives the correct value of m, the number of months for which Plans A and B cost the same is,

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
