There isnt a picturee but when you add another question I will hep you the best I can :)
I need points and i’m using this bc you didn’t even give an equation
Answer:
X = 12
Y = 4
Step-by-step explanation:
X + Y = 16
X = 3Y
3Y + Y = 16
4Y = 16
Y = 4
X + 4 = 16
X = 12
Answer:
$120.1355
Step-by-step explanation:
We can model this as an exponencial function:
P = Po * (1+r)^t
Where P is the final value, Po is the inicial value, r is the rate and t is the amount of time.
For this case, we have that Po = 900, r = -25% = -0.25 and t = 7, so we can find the value of P
P = 900 * (1 - 0.25)^7 = $120.1355
The price after 7 years will be $120.1355.
Answer:
The probability that Jason will get exactly 7 strikes out of 10 attempts is 0.117.
Step-by-step explanation:
We are given that Jason is a very good bowler and has proven over the course of a season of league play that he gets a STRIKE 50% of the time.
Also, Jason has been given 10 attempts.
The above situation can be represented through binomial distribution;
where, n = number trials (samples) taken = 10 attempts
r = number of success = 7 strikes
p = probability of success which in our question is % of the time
he gets a strike, i.e; p = 50%
<em><u>Let X = Number of strikes Jason get</u></em>
So, X ~ Binom(n = 10, p = 0.50)
Now, probability that Jason will get exactly 7 strikes out of 10 attempts is given by = P(X = 7)
P(X = 7) =
=
=
= <u>0.117</u>
Therefore, the probability that Jason will get exactly 7 strikes out of 10 attempts is 0.117.
