Samir spins a fair coin and records the results. In the first four spins ‘Heads' comes up each time. Samir says, ‘A head is more likely than a tail'. Is he correct? YES/ NO Give a reason for your answer.
Answer:
No
Step-by-step explanation:
A coin has two sides which is the "Head" or the "tail". When a coin is tossed, since it only has two sides, one of either sides can come up because they both have 50-50 chance. The probability of having heads or tails is 0.5 or ½ and either side can come up.
Mathematically,
½ × ½ × ½ × ½ = ¹/₁₆
The probability of getting heads four times in a row when the coin is tossed is ¹/₁₆.

The planner needs a clearance of 9 feet under the arch. Has the planner met the minimum height?
Answer:
Yes,planner has met the minimum height, as minimum height was 9 feet and maximum height of arc is 9.6 feet
Step-by-step explanation:
The question is incomplete as all the details have not been given in the question.I have attached the complete question and its options at the bottom. Consult in for better understanding.
As we can see that at the mid value, for x=4, the value of f(x)=9.4
It means that the maximum height occurs at mid of the arc where it is height is 9.6 feet above the ground.
It means that the planner has met the minimum height, as minimum height was 9 feet and maximum height of arc is 9.6 feet
Answer:
B on Edge

find the least positive integer for which the sum of its reciprocal and 9/10 is greater than 4 times the reciprocal
Answer:
4
Step-by-step explanation:
You want the least positive integer x such that ...
1/x +9/10 > 4/x
9/10 > 3/x . . . . subtract 1/x
3/10 > 1/x . . . . .divide by 3
x > 10/3 . . . . . multiply by 10x/3
The least positive integer satisfying this requirement is x = 4.
10 points question please help A water faucet turned 2 1/7 to the right and the 1 3/4 to the right again. How far has the facet turned?
Answer:
The faucet has turned a total distance of 3 25/28
Step-by-step explanation:
To know the total distance turned by the faucet, what we need to do is to add together the distances to which it has turned.
Mathematically, that would be;
2 1/7 + 1 3/4
which is;
15/7 + 7/4 = (60 + 49)/28 = 109/28 = 3 25/28

A straight line passes through the origin and has a gradient of 4. Find the equation
Answer:
y = 4x
Step-by-step explanation:
The slope is 4.
The line passes through (0, 0).
Equation of a line y = mx + b, m is the slope, and b is the y-intercept.
y = 4x + b
Put x and y as 0.
0 = 4(0) + b
0 = b
The y-intercept is 0.
The equation of the line is y = 4x.

what is the solution to the inequality below? 2(x-15)> x/2
Answer:
x>20
Step-by-step explanation:
2(x-15)>x/2
2x-30>x/2
Multiply both sides by 2
4x-60>x
Subtract 4x from both sides
-60>3x
-20<x
Answer: x>20

Instructions: Write the explicit rule. Remember to simplify and do not put spaces in your answer. Sequence: 30,0,−30,−60,… 30 , 0 , − 30 , − 60 , … = a n = Answer
Answer:
a(n)=60-30n
Step-by-step explanation:
Equation to use:
a(n) = a(1) + d(n-1)
where a(1) is the first term, d is the common difference between terms, and n is the nth term you are trying to find.
In this case, a(1) is 30, d is -30, and n is just n.
If you plug that into the equation and use the distributive property, you would get: a(n) = 30 -30n + 30.
Adding the two 30's gets you: a(n) = 60 - 30n, which is the solution.
Which of these graphs represents a function?
Answer:
first and second
Step-by-step explanation:
the last 2 have angles wich make that value given by several numbers
Step-by-step explanation: Here were given 4 relations in the form of graphs and were asked to determine which one represents a function.
In this situation, we would use what is called the vertical line test.
In other words, if we can draw a vertical line that passes through
more than one point on the graph, then the relation is not a function.
Notice that in this problem, every vertical line draw on a
graph passes through more than 1 point except for W.
So W represents a function.

Please explain how you would prove that all circles are similar?
Answer:
Shapes are similar when one can be scaled to be like another one. Circles are always the same shape and they only vary in size. A very small circle can be expanded to be the same size as any other without changing it's shape, only size. However this is not true for ovals since they come in different shapes.

Answer:
b
Step-by-step explanation:
A line sloping upwards from left to right has a positive gradient.
A line sloping downwards from left to right has a negative slope
If the line crosses the y- axis above the x- axis then y- intercept is positive.
If the line crosses the x- axis below the x- axis then y- intercept is negative.
The line shown slopes downwards from left to right, thus negative gradient
The line crosses the y- axis above the x- axis thus y- intercept is positive
The two top NBA players played a basketball game against the RSM team. Together the NBA players made 85 baskets, scoring one point for free throws and two or three points for field goals. They scored a total of 184 points during the game. If they made 22 free throws, how many three-point field goals did they make
Answer:
They made 36 three-point field goals
Step-by-step explanation:
For free throws , we have one point each.
So here, the total points they made from free throws is 22 * 1 = 22 points
So the number of points made from field goals would be 184-22 = 162 points
So the issue we have now is knowing the number of 3-point field goals that was made.
How can we get this?
Remember they made 85 baskets? so if we subtract the number of free throws, then we can have the number of field throws and that is 85-22 = 63
Now, let the number of 2 points throws be x and the number of 3 points throws be y
From our earlier analysis;
x + y = 63 ••••••••• (i)
Now the total number of three pointers would be 3 * y = 3y and the total number of two pointers would be 2 * x = 2x
Adding both gives a total of 162
Thus;
2x + 3y = 162 •••••••• (ii)
So we have two equations to solve simultaneously.
From equation 1, we can say that;
x = 63-y
Let’s substitute this into equation 2
2(63-y) + 3y = 162
126 -2y + 3y = 162
126+y = 162
y = 162-126
y = 36
This means that they made 36 three-point field goals
Answer:
They made 36 three-point field goals during the game

Answer: Part 1: 111.24
Part 2: 9.27
Part 3: 54 minutes
Step-by-step explanation:
Part 1: Since you already know that the total bill increases by 3%, you just have to find 103% of 180.
1.03*108= 111.24; your answer would be 111.24 pounds
Part 2: Since you already know yearly, 111.24 divided by 12= 9.27 per month
Part 3: First find 73% of 200 which is 146. Then subtract that from 200 which is 54. So you have 54 minutes left.
5) El peso en kilos de 9 niños es 15, 25, 17, 19, 16, 26, 18, 19 ,24 a) ¿Cuál es la media y mediana? El promedio es 20 b) ¿Cuál es la mediana si incluimos el peso de otro niño que pesa 43 kg? c) En el segundo caso ¿sería la media aritmética un buen representante de los 10 datos? Argumenta tu respuesta.
Respuesta: 19; 19,89
B) 19 C) No
Explicación paso a paso:
Dados los datos:
15, 25, 17, 19, 16, 26, 18, 19, 24
Reorganizando los datos:
15, 16, 17, 18, 19, 19, 24, 25, 26
Mediana de los datos:
(N + 1) / 2
Donde N = número de observaciones
Mediana = (9 +1) / 2 = 10/2 = 5 a observación = 19.
Media = suma de valores observados / número de observaciones
Media = (15 + 16 + 17 + 18 + 19 + 19 + 24 + 25 + 26) / 9
Media = 179/9 = 19.89
B) mediana si se agrega otro niño que pese 43 kg
Los nuevos datos se convierten en:
15, 16, 17, 18, 19, 19, 24, 25, 26, 43
Mediana = (N + 1) / 2
Mediana = (10 + 1) / 2 = 11/2 = 5.5 Como tenemos un decimal:
La mediana será el promedio de la quinta y sexta observación: (19 +19) / 2 = 38/2 = 19
C) No, la media aritmética no parece ser un buen representante de la observación de 10 datos con el valor de peso recién agregado de 43 kg, ya que el valor parece considerablemente más alto que el conjunto de los 9 valores anteriores. Con el peso recién agregado, la media aritmética se convierte en: Media = (15 + 16 + 17 + 18 + 19 + 19 + 24 + 25 + 26 + 43) / 10 Media = 222/10 = 22.2
