Answer:
If all you care about is whether you roll 2 or not, you get a Binomial distribution with an individual success probability 1/6. The probability of rolling 2 at least two times, is the same as the probability of not rolling 2 at zero or one time.
the answer is, 1 - bin(k=0, n=4, r=1/6) - bin(k=1, n=4, r=1/6). This evaluates to about 13%, just like your result (you just computed all three outcomes satisfying the proposition rather than the two that didn’t).
Step-by-step explanation:
The probabilities of getting :
O Threes is 0.48
1 Three is 0.095
2 Threes is 0.019
3 Threes is 5/1296
4 Threes is 1/1296
What is a binomial distribution ?When each trial has the same probability of achieving a given value, the number of trials or observations is summarized using the binomial distribution.The likelihood of observing a specific number of successful outcomes in a specific number of trials is determined by the binomial distribution.A popular probability distribution known as the binomial distribution simulates the likelihood of getting one of two outcomes given a set of parameters.It totals the number of trials when each trial has an equal chance of producing a particular result.the total out come = 6* 6* 6* 6 =1296
Find the probabilities of getting
O Threes =(5/6)^4 = 0.48
1 Three = 1/6*(5/6)^3 = 0.095
2 Threes = 1/6* 1/6* 5/6 *5/6 =0.019
3 Threes = 1/6* 1/6* 1/6 *5/6 = 5/1296
4 Threes =(1/6 )^4 =1/1296

A rectangular room is 15 meters longer than it is wide, and it’s perimeter is 26 meters. Find the dimensions of the room
Answer:
the room is -1m by 14m
Step-by-step explanation:
what you do to find it is first find x.
the perimeter is 26, and one side is 15 meters longer than the other(twice).
So the equation is:
x + (x + 15) + x + (x + 15) = 26
2x + 2(x + 15) = 26
2x + 2x + 30 = 26
4x + 30 = 26
26 - 4x = 30
26 - 26 - 4x = 30 - 26
-4x = 4
-4x/-4 = 4/-4
x = -1
Now we have two sides of the room. Now we want the 15m longer ones...
-1 + 15 = 14
so the dimensions are -1 by 14, or -1x14

14 Type the correct answer in each box. Use numerals instead of words. a Ava, Lucas, and Maria are playing a game where they pass a pull-back toy to one another in a path that forms a right triangle. Ava sends the toy to Lucas. Then, Lucas sends the toy to Maria. Finally, Maria sends it back to Ava. The angle formed at Lucas' position measures 90° and the angle formed at Ava's position measures 40°. The distance from Ava to Lucas is 12 feet. Ava is trying to determine the other measures of the triangle created by the toy's path. Give each distance in feet rounded to the nearest tenths place. The distance from Maria to Ava is feet. The distance from Lucas to Maria is feet. The angle formed at Maria's position measures degrees.
Answer:
Maria–Ava: 15.7 feetLucas–Maria: 10.1 feetangle at Maria: 50°Step-by-step explanation:
The cosine and tangent functions are useful here. The relevant relations are ...
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
__
The distance from Maria to Ava (ma) is the hypotenuse of the triangle, so we have ...
cos(40°) = 12/ma
ma = 12/cos(40°) ≈ 12/0.76604 ≈ 15.7 . . . feet
__
The distance from Lucas to Maria (ml) is the side opposite the given angle, so we have ...
tan(40°) = ml/12
ml = 12·tan(40°) ≈ 12·0.83910 ≈ 10.1 . . . feet
__
The angle formed at Maria's position is the complement of the other acute angle in the right triangle:
M = 90° -40° = 50°

Answer:
Graph CStep-by-step explanation:
We can solve it without actually plotting the inequalities.
Observations:
Both lines have positive slopes and both have same inequality symbol ⇒ ≤It means both shaded regions are below the lines and the lines are solid.The y-intercepts, the steeper line has b = - 3 and the other line has b = 2All the above observations are reflected on the graph C only.

A mug holds 450 ml. How many mugs will be needed to fill up a bucket of 36 litres capacity?
please help me guys I will do anything
Answer:
80 mugs of 450 ml each is needed to fill up a bucket of 36 litres.
Step-by-step explanation:
Capacity of mug = 450 ml
Capacity of bucket = 36 litres
= (36 × 1000) ml [since, 1 litre = 1000 ml]
= 36000 ml
Therefore, number of mugs needed to fill the bucket = 36000/450
= 80
Hence, 80 mugs of 450 ml each is needed to fill up a bucket of 36 litres.

6x+3y=21
2x−3y=−13
Answer:
Elimination
Step-by-step explanation:
+3y and -3y are opposites so they can cancel out. This would give you 8x=8 so now you know x=1. now substitute the 1 into an equation:
6(1)+3y=21
6+3y=21
3y=15
y=5
x=1
Write the number for twenty-nine million seven thousand.
Answer:
2907000
Step-by-step explanation:
Answer and Step-by-step explanation:
In order to solve this, you must look at the placements:
Millions, Thousands, Hundreds (in hundreds are: Tens, Ones)
Now that we know that, we can now determine what the answer is to this problem. Because we have 29 million, we fill this into the millions placement:
29, _ _ _, _ _ _
Then we fill in 7 thousand:
29,007, _ _ _
And because we have no hundreds, the rest are zeros.
The answer is: 29,007,000.

If you were given a large data sets such as the sales over the last year of Amazons top 100 customers what might you be able to do with these data? What might be the benefits of the describing the data? How would you display the data?
Answer:
The best thing to do with data such as sales over the last year of the top 1000 customers would be to answer questions like:
1) what products sell the most: This would help the marketing department,for example on targeting what items to push.
2) what groups of people buy what product: Again this would be targeting who buys what. We may discover that males prefer product A and females prefer product B. Or young customers prefer different products that older. This would help marketing also on targeting sales.
