-x + 2y = -1....when x = 15...so we sub in 15 for x and find y
-15 + 2y = -1
2y = -1 + 15
2y = 14
y = 14/2
y = 7 <==

Which additional information is needed to solve this problem?
liq [111]
Hi there!

The answer is B.
the cost of the game.

We need to know the cost of the game in order to find out how many weeks John has to save money. If we don't know this price, we'll never know whether John has saved enough money.

We can find out the total amount of money John can save in 1 week (so A. is not the answer). The amount of money John earns per hour doesn't matter to answer the question (so C. is wrong).

~ Hope this helps you!

Can someone help me with this question?
belka [17]

Answer:

The required probability is 0.0155.

Step-by-step explanation:

We are given that the one-year survival rate for pancreatic cancer is 20%.

Of 12 people diagnosed with pancreatic cancer at one hospital, 6 survived one year.

The above situation can be represented through binomial distribution;

P(X=r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r} ; x = 0,1,2,3,......

where, n = number of trials (samples) taken = 12 people

            r = number of success = 6 survived

            p = probability of success which in our question is probability of

                  one-year survival rate for pancreatic cancer, i.e; p = 20%

Let X = <u><em>Number of people survived one year</em></u>

So, X ~ Binom(n = 12 , p = 0.20)

Now, the probability that 6 survived one year is given by = P(X = 6)

              P(X = 6)  =  \binom{12}{6} \times 0.20^{6} \times (1-0.20)^{12-6}

                             =  924 \times 0.20^{6} \times 0.80^{6}

                             =  <u>0.0155</u>
