The probability of flipping a coin 85 times and getting tails 50 times or fewer 99.8%, the correct option is B
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that;
The coin is flipped 85 times
Now,
The probability of flipping a coin and getting tails on any single flip is 0.5 (assuming it's a fair coin). We can model this scenario using a binomial distribution, where:
n = 85 (the number of coin flips)
p = 0.5 (the probability of getting tails on any single flip)
x = 50 (the maximum number of tails we want to allow)
We want to find the probability of getting 50 tails or fewer, so we need to calculate the cumulative probability of the binomial distribution up to x = 50. We can use a binomial probability calculator or a spreadsheet program to do this calculation.
Using a binomial probability calculator, we get:
P(X ≤ 50) = 99.8%
Therefore, the probability will be 99.8%.

Find Ms. Buggie's mistake in the following problem. Then, give what the correct answer should be.
Find the measurement of angle LKA.
Answer:
Mrs. Buggie should have Subtracted 13 instead of adding 13
LKA = 94°
Step-by-step explanation:
Lets work backwards from the equation so far:
40 = x+ 13
x + 13 = 40
We should subtract 13 because we are adding a number and 13 to 40
Imagine this:
You have 5 apples, but you bought some more and now you have 10
equation would be:
5+x = 10
subtract 5 from 10 to get 5
So you bought 5 apples
Back to the Question:
40 - 13 = 27
3(27) + 13 = 81+13 = 94°
Answer = 94°

Answer:
1.) x=-7
2.) x= -8
3.) x=13
4.) x=2
Step-by-step explanation:
ur lucky idc
1. 4x = -28
By dividing both sides of this equation by 4, we see that x = -7.
2. x - (-6) = -2
Note that x - (-6) is equal to x + 6. To solve the equation x + 6 = -2, subtract 6 from both sides to see that x = -8.
3. -x + 4 = -9
First, subtract 4 from both sides to get that -x = -13. Then, multiply both sides by -1 to see that x = 13.
4. -3x + 7 = 1
First, subtract 7 from both sides to get that -3x = -6. Then, divide both sides by -3 to see that x = 2.

Step-by-step explanation:
3x + 2(4x − 6) = 8x + 1
3x + 8x - 12 = 8x + 1

If 1/8 of my money is $80. What is 50 % of my money
Answer:
$320
Step-by-step explanation:
An easy way to solve this problem is to undo the operations, Find the total amount of money, and then find half of the amount. Since (80) is ([tex]\frac{1}{8}[/tex]) the total amount of money, one has to multiply (80) by (8) to find the total amount of money.
(80) * (8)
= 640
Now one is asked to find (50%) of the money. It is known that (50%) is equivalent to (0.5), therefore multiply (640) by (0.5) to find how much (50%) of the money is.
(640) * (0.5)
= 320

I need help math work (geometry) :P
Answer:
x = 6
Step-by-step explanation:
For the triangles to be similar then the ratios of corresponding sides would be equal, that is
[tex]\frac{DF}{XZ}[/tex] = [tex]\frac{DE}{XY}[/tex] , substitute values
[tex]\frac{3(x-1)}{7.5}[/tex] = [tex]\frac{10}{x-1}[/tex] ( cross- multiply )
3(x - 1)² = 75 ( divide both sides by 3 )
(x - 1)² = 25 ( take the square root of both sides )
x - 1 = ± [tex]\sqrt{25}[/tex] = ± 5 ( add 1 to both sides )
x = 1 ± 5 , then
x = 1 + 5 = 6 or x = 1 - 5 = - 4
But x > 0 then x = 6
For the triangle to be similar then x = 6

If f(x) = x3 - 12x2 + 44x - 48, which of the following is not a factor of f(x)? O (x + 4) O (x - 6) O (x - 2) O (x - 4)
Answer:

x - 2 = 0, so x = 2
x - 4 = 0, so x = 4
x - 6 = 0, so x = 6
The option which is not a factor of the cubic equation is (x+4)
What are cubic equations?The algebraic equations having variables with power 3 are referred to as cubic equations. A generalized form of a cubic equation is ax³+ bx²+ cx + d = 0.
Given here: The cubic function f(x)=x³-12x²+44x-48
Clearly in the options the list of factors are -4,6,2,4
Checking for all 4 options we get
f(-4)=-4³-12×4²+44×(-4)-48
=-64-192-176-48≠0
f(6)=6³-12×6²+44×(6)-48
=216-12×36+264-48
=0
f(2)=2³-12×4+44×2-48
=8-48+88-48
=0
Similarly we can find for x=4 that f(4)=0
Hence, The option which is not a factor of the cubic equation is (x+4)
