A fair coin is tossed 5 times. Compute the probability of tossing 5 heads in a row.
Answer:
50%
Step-by-step explanation:
There is 2 side out of 100% half is 50 :D gl and mb if its wrong!
Answer:
* Here we assume that the coin tossed is fair.
Probability of event A = # Favorable cases for event A/ # Exhaustive cases for event B
Where
Favorable cases means outcomes of an experiment that favors a particular event
Exhaustive cases means, number of total possible outcomes.
For tossing a coin one time:
# Favorable cases = 1 (getting head)
# Exhaustive cases = 2 (two outcomes, say, head and tail)
So, P(getting head in a single toss) = 1/2
For tossing a coin two times:
# Favorable cases = 1 (getting 2 heads, say, HH)
# Exhaustive cases = 2*2 or 2^2 (4 outcomes, say, HH, HT, TH, TT)
So, P(getting 2 heads in two tosses of a coin) = 1/4
Similarly, for tossing a coin five times:
# Favorable cases = 1 (getting 3 heads, say, HHHHH)
# Exhaustive cases = 2*2*2*2*2 or 2^5 (32 outcomes, say, HHHHH, THHHH, ..... etc)
So, P(getting head in 5 tosses of a coin) = 1/32

In a model based on a weakly dependent time series with serial correlation and strictly exogenous explanatory variables, _____. a. the feasible generalized least square estimates are BLUE b. the feasible generalized least square estimates are asymptotically more efficient than OLS estimates c. the feasible generalized least square estimates are unbiased d. the feasible generalized least square estimates are asymptotically less efficient than OLS estimat
Answer:
Option a (the feasible........BLUE) is the correct option.
Step-by-step explanation:
The association with a certain variable and perhaps a lagging representation with its own over time is termed as Serial correlation. OLS could even deliver skewed outcomes and can't thus be utilized attributable to serial correlation. GLS has always been then used that follows BLUE, in other words, GLS even though in this circumstance becomes an appropriate Unbiased Linear Estimator.The other alternatives are not related to the given scenario. So the above is the right option.
If A =

x = [?]
Enter
Answer:
x = 7
Step-by-step explanation:
Based on the angle bisector theorem, we would have the following equation:
21/(3x - 12) = 14/6
21/(3x - 12) = 7/3
Cross multiply
(3x - 12)*7 = 3*21
21x - 84 = 63
21x - 84 + 84 = 63 + 84
21x = 147
21x/21 = 147/21
x = 7

plz help i need to know 94=10a-7 and 7k+10=31
Answer:
a=10.1
k=3
Step-by-step explanation:
Lets solve the first equation first.
94=10a-7
Lets add 7 to both sides.
101=10a
Divide both sides by 10 to isolate a
101/10=a
a=10.1
Lets do the second equation.
7k+10=31
Subtract 10 from both sides
7k=21
Divide 7 by both sides to isolate k
k=3

What is the measured of bacteria at t=0?
Answer:
Number of bacteria when t = 0 is 2,000
Step-by-step explanation:
Given:
Number of bacteria in a culture by equation
Q(t) = 2(729^t)
Value of t = 0
where t is number of hours
Find:
Number of bacteria when t = 0
Computation:
Given equation
Q(t) = 2(729^t)
Put t = 0
Q(0) = 2(729⁰)
We know that;
a⁰ = 1
So,
Q(0) = 2(729⁰)
Q(0) = 2(1)
Q(0) = 2
Number of bacteria when t = 0 is 2,000
