Answer:

t=2

Step-by-step explanation:

log4(7t+2)=2

Raise each side to the base of 4

4^log4(7t+2)=4^2

The log goes away

7t+2 = 16

Subtract 2 from each side

7t+2-2 = 16-2

7t = 14

Divide each side by 7

7t/7 = 14/7

t = 2

Answer:

y = 6.50x + 6 or 71 = 6.50x + 6

10 people are the max you can invite

Step-by-step explanation:

We have the simple equation

y = 6.50x + 6

6.50x because it it per person

6 because it is a flat one time charge

We want the max to be 71 so that will be our y

71 = 6.50x + 6

We are now going to solve for x

65 = 6.5x

x = 10

Hope it helps! (:

Pink:
10 * 10 = 100

Blue:
10 * 4 = 40

Purple:
9 * 10 = 90

Green:
4 * 9 = 36

Add them all together.
100 + 90 + 40 + 36 = 266

Have an awesome day! :)

If the probability that the Islanders will beat the Rangers in a game is 0.38, what is the probability that the Islanders will w

natali 33 [55]

Answer:

0.014

Step-by-step explanation:

The probability that the Islanders will win at least 6 out of seven is the probability of them winning exactly 6 games, P(X=6), added to the probability of them winning all seven games, P(X=7).

This problem can be treated as a binomial probability model with probability of success p = 0.38 in each of n = 7 games.

$P(X=x) = \frac{n!}{(n-x)!x!}*p^ x*(1-p)^{(n-x)}$

Thus:

$P(X=6) = 7*0.38^6*0.62\\P(X=6) =0.01307\\P(X=7) = 0.38^7\\P(X=7) =0.00114$

The probability is:

$P(X\geq 6) = 0.01307+0.00114\\P(X\geq 6) = 0.014$

The probability that the Islanders will win at least six out of seven games in a series against the Rangers is 0.014.
