The proportion of heads after the first 10 tosses of a coin is zero i.e 0/10 = 0
A probability is a number that reflects the likelihood or probability that a particular event will occur. Probabilities can be expressed as percentages ranging from 0 to 1, and can also be expressed as percentages ranging from 0% to 100%. A probability of 0 indicates that the particular event is unlikely to occur, and a probability of 1 indicates that the event will definitely occur.
Probability is calculated by dividing the number of ways the event can occur by the total number of outcomes.
We have given the following points ,
A coin is tossed 10 times and it comes with tail in each time of first 10 tosses.
When a coin is toosed , there two possibilities either it comes with head or tail. Both can't be come at once.
As we see first ten tosses of a coin gives tails as a result . Then, there is no chance of occurrence head in first 10 tosses.
So, there in no heads in first 10 tosses. The probability or proportion of heads after the first 10 tosses is 0/10 = 0..

#Complete Question:
Probability works not by compensating for imbalances but by overwhelming them. Suppose that the first 10 tosses of a coin give 10 tails and that tosses after that are exactly half heads and half tails. (Exact balance is unlikely, but the example illustrates how the first 10 outcomes are swamped by later outcomes.) (Use decimal notation. Give your answers as exact numbers.)

amy is making donuts as shown below the donut has a diameter of 5 inches and the center has a radius of 1 inch . what is the approximate area of the dunut? use 3. 14 for n
Answer:
The area of the dount is about 35.325 in²
Step-by-step explanation:
In order to find the area of a donut with a hole on the center we need to find the area of the center and the area of the circle of the donut (as if the donut was whole)
*The radius is half of the diameter or r = d/2
The area of a circle is A = n(3.14) r² or pi(3.14)× radius
Find the area for the center of the donut which is 3.14 × 1² which is 3.14 in² Find the area of the circle of the donut which is 3.14 × (5/2)*² the answer would be 38.465 Subtract the empty space from the rest of the donut so 38.465 - 3.14. The final answer is 35.325 in²a 13 card hand is dealt from a well-shuffled standard 52-card deck. what is the probability that 2 red cards and 11 black cards are dealt?

Mrs. Wong is researching what it would cost to order flower arrangements for a fancy party. She wants one large centerpiece for the head table, and smaller arrangements for the smaller tables. Lakeside Florist charges $19 for each smaller arrangement, plus $50 for the large centerpiece. Spencer's Flowers, in contrast, charges $42 for the large centerpiece and $23 per arrangement for the rest. If Mrs. Wong orders a certain number of small arrangements, the cost will be the same at either flower shop. How many small arrangements would that be? What would the total cost be?
Step-by-step explanation:
so, we have 2 cost functions. each consisting of 1 large centerpiece, and x smaller arrangements.
cost1(x) = 19x + 50
cost2(x) = 23x + 42
to get the value for x we know that the cost is the same either way.
that means
cost1(x) = cost2(x) = 19x + 50 = 23x + 42
19x + 50 = 23x + 42
50 = 4x + 42
8 = 4x
x = 2
so, she orders 2 small arrangements.
the total cost is
19×2 + 50 = 38 + 50 = $88
cross check with the other function :
23×2 + 42 = 46 + 42 = $88

line JK passes through points J(-4,-5) and k(-6,3). if the equation of the line is written in slope-intercept form, y=mx+b, what is the value of b?
The value of b of the equation is -9/5
How to find the value of b with the equation in slope-intercept form?Given that: line JK passes through points J(-4,-5) and K(-6,3) and if the equation of the line is written in slope-intercept form, y=mx+b
The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system
Using the y-y₁/y₂-y₁ = x-x₁/x₂-x₁
where (x₁, y₁) = (-4,-5) and (x₂, y₂) = (-6,3), the equation is:
y-(-5) / 3-(-5) = x-(-4)/-6-(-4)
y+5 / 3+5 = x+4 /6+4
(y+5)/8 = (x+4)/10 cross multiply:
10(y+5) = 8(x+4)
10y + 50 = 8x + 32
10y = 8x +32 - 50
10y = 8x - 18
y = 8x/10 - 18/10
y = 4x/5 - 9/5
Comparing y = 4x/5 - 9/5 with y=mx+b
b = -9/5
Therefore, the value of b is -9/5

What is the effect on the graph of y = 2x + 2
when it is changed to y = 2x-2?
Answer:
shifted down 4 units
Step-by-step explanation:
You want to know the effect on the graph of changing y=2x+2 to y=2x-2.
Y-interceptThe constant in the equation y=2x+2 is the y-intercept. The line described by this equation crosses the y-axis at y=2.
When the equation is changed to y=2x-2, the y-intercept changes from +2 to -2, a shift down of 4 units. The shifted line has the same slope as the original, so is parallel to it.
The effect on the graph is to move it down 4 units.

given that £1 = $1.62
how much is £650 in $
Answer:
$1053
Step-by-step explanation:
If we have that £1 = $1.62, then we can multiply both sides by 650 in order to get £650 on the left side of the equality. We must multiply the right side also by 650, and so we get £650=$1.62 * 650.
To do this multiplication, we can break 1.62 down simply into $1.00 +$0.6+$0.02
650*$1.00=$650, 650*$0.6=650*6/10=65*6=$390, and 650*$0.02=650*2/100=6.5*2=$13.
When we add these three products together, we get $650+$390+$13=$1053. And so, £650=$1053
