Answer:
The probability distribution of X is:
Step-by-step explanation:
"Tossing a coin and getting H" can be modelled as a Bernoulli random variable. The variable X is a sum of 4 of this Bernoulli variables, we can model X as a binomial random variable, with p=0.5 and n=4.
The values X can take are: 0, 1, 2, 3 and 4.
The values of this probability are calculated as:
Where
p: is the probability of tossing a coin and getting a Heads
q: is the probability of tossing a coin and not getting a Heads.
The binomial number is a way to calculate the possible combinations of getting a certain amount of heads.
For example, in 4 tosses, there are 6 ways or combinations of getting 2 heads and 2 tails:
Answer:
1/2 pounds per tablespoon
Step-by-step explanation:
48 ounces of chili = 3 pounds of chili
Because he used 2 tablespoons of chili powder in the first batch, he used 6 tablespoon of chili powder in the 2nd batch. Which is a lot!
So for every tablespoon he used, he had 1/2 pounds of ground beef alongside it! I hope this helped!

Question:</u></h3>
"To get the next term in the sequence,multiply the last term by 2.5 . What is the value of the next term?
1 , 2.5 , 6.25, 15.625, ..."
<h3><u>Answer:</u></h3>
The value of the next term is 39.0625
<h3><u>Solution:</u></h3>
Given that the series is 1 , 2.5 , 6.25, 15.625
When we divide 2nd term by first we get 2.5 , similarly for other successive number when we divide them with their preceding number we get a value of 2.5
So, all the successive numbers are 2.5 times of their previous number
So the value of next term is 39.0625
Let the number of songs Lou has = X
Kelly has 4 times as many as Lou, which would be written as 4X
Tiffany has 6 times as many songs as Lou, which would be written as 6X
The total number of songs = 682
You need to add all three people together to equal 682
So you would get:
X + 4X + 6X = 682 songs.
Combine all like terms ( 6x + 4x + X = 11x)
11x = 682
Now to solve for X divide both sides by 11:
x = 682 / 11 = 62
Lou = x = 62 songs.
Kelly = 4x = 4(62) = 4*62 = 248 songs.
Tiffany = 6x = 6(62) = 6 *62 = 372 songs.
Answer:
He cannot drink and drive, we cannot use this in maths as drinking has adverse effects on any person at any time no matter how many units you drink. The answer is zero.
Step-by-step explanation:
Expansion to adverse effects is factual to what achohol and drugs do to your mind even though people keep pace under any small intake of say drink the facts are that drink reduces reaction times and has a chemical effect with choline in the brain.
