50% or 1/2 Could be 100% but i think it is 50%
Step-by-step explanation:
Because Changing the coin will make no difference.
The probability of getting heads is same as the probability of tails which is [tex]\frac{1}{2}[/tex].
What is the probability?
The concept of probability is used to assign a numerical description to the likelihood of occurrence of an event.
Probability can be defined as the number of favorable outcomes divided by the total number of possible outcomes of an event.
Here given that,
The [tex]10[/tex] tosses of a coin were all heads, and you switch to a new coin.
So, the probability of getting all heads is [tex]2^{-n}[/tex]
And we have [tex]n=10[/tex],
Then, the probability of getting the heads is
[tex](^{n}C_k)(\frac{1}{2})^k(\frac{1}{2})^{n-k}=2^{-n}(^nC_k)[/tex]
Hence, the probability of getting heads is same as the probability of tails which is [tex]\frac{1}{2}[/tex].

If the base of a rectangle is 27.4 mm and the area is 420.92 mm2 what is the height of the rectangle?
Answer:
15.36mm
Step-by-step explanation:
The area of a triangle can be defined as B x H or L x H,
In your case, I'm assuming you meant base as length, so just plug into the equation:
L x H = 420.92mm2
27.4 x H = 420.92
H = 15.36
If you want to be exact, it is 15.3620438
The required height of the rectangle is 15.36 for the base of a rectangle is 27.4 mm and the area is 420.92 mm2.
The base of a rectangle is 27.4 mm.
The area is 420.92 mm2.
What is the height of the rectangle is to be determined.
The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°. Beside of square its pair of opposide sides are named as length and width sometimes base and height according to the mentions.
The area of a rectangle is a product of is two adjacent sides i.e. length * width
Area of the rectangle = height * base
420.92 = 27.4 * height
height = 420.92/27.4
height = 15.36
Thus, the required height of the rectangle is 15.36 for the base of a rectangle is 27.4 mm and the area is 420.92 mm2.

The point (-2, k) lies on the line 2x – 4y + 3 = 0.
Find the value of k.
Answer:
k = (-1/4)
Step-by-step explanation:
Given that,
The point (-2, k) lies on the line 2x – 4y + 3 = 0.
We need to find the value of k.
Put x = -2 and y = k in the given equation.
2(-2) – 4k + 3 = 0
-4-4k = -3
-4+3 = 4k
-1 = 4k
k = (-1/4)
So, the value of k is equal to (-1/4).

What distinguishes a market economy from a free-enterprise economy?
A market economy is based on set prices that businesses use to produce goods that consumers need.
A free-enterprise economy allows the government to freely regulate the quantity of items produced as supply decreases in a market economy.
A market economy is based on supply and demand, and a free-enterprise economy is based on relying on demand to produce products to make money.
In a market economy, the supply and demand of goods is determined by consumers who are free to set their own prices in a free enterprise
Answer:
Well that question could have multiple answers... one of them being set prices, and money balances. Another being product demand on goods and services. It's really your choice on what you think distinguishes these factors. There's to many opinions on this to just give one answer.

If you add up all of the numbers without including the last one you get 201. You need that number to be 240 because 240÷10=24. So the missing number is 39.

For parties of six or more, a restaurant adds a 20% gratuity (or tip). If a
dinner bill for a large party comes to $148.25, find the total dinner bill with
tip.
Answer: tThe total dinner bill with tip = $177.90
Step-by-step explanation:
Given: Dinner bill = $148.25
Tip percent = 20%= 0.20
Total dinner bill = Dinner bill + Tip percent × (Dinner bill)
Total dinner bill = $ (148.25+0.20×148.25)
Total dinner bill = $ (148.25(1.20))
Total dinner bill = $177.90
Hence, the total dinner bill with tip = $177.90
