there were 3 coins and they were tossed 200 times total. 23 times, 3 of them showed heads, 72 times, 2 of them showed heads, 77 times, 1 of them showed heads, 28 times, 0 showed heads. whats probability for each of the events?
Answers
Answer:
Step-by-step explanation:
If the three coins are simultaneously tossed again, compute the probability of 2 heads coming up.Solution:Probability of an event, P(E) = Number of occurrences where the event takes place / Total number of occurrencesThe probability of 2 heads coming up when three coins are tossed simultaneously is given by the ratio of the number of times a particular outcome occurs to the total number of tosses.Total number of tosses = 200Number of 2 heads outcomes = 72Probability of 2 heads outcomes = Number of 2 heads outcomes / Total number of tosses= 72/200= 9/25

given f(x)= 8x+1/2x-9 what is the end behaviors of the function
Answers
The behavior of the function f(x) describes the direction of the function
The behavior of the function is as x -> ∞, f(x) -> 4 and x -> -∞, f(x) -> 4
How to determine the end behavior?The function is given as:
f(x)= 8x+1/2x-9
Start by plotting the graph of the function f(x).
From the graph (see attachment), we have the following highlights:
The function has an asymptote at y = 4This means that: as x approaches infinity or negative infinity, f(x) approaches 4Hence, the behavior of the function is as x -> ∞, f(x) -> 4 and x -> -∞, f(x) -> 4

Step-by-step explanation:
There are L, O, O, P, H, O, L, E; 8 letters in LOOPHOLE. However, three letters repeat: OOO. That means we cannot count them as different and use ! for them.
L,P,H,L,E,O are the letters not double counted. There are SIX letters, so 6!, however, you still have to divide since there are the Os you have to consider.
You have to divide by 3! as they repeat 3 times.
Thus, 6!/3!

In general, repetitions are taken care of by dividing the permutation by the factorial of the number of objects that are identical" -www. ck12. org > probability > lesson > permutation

Step-by-step explanation:
[tex]\sf \cfrac{x^2+10+25}{x+5}-\cfrac{x^2-6}{x-5}[/tex]
First, Let's factor the expressions that are not already factored in x^2+10+25/x+5
[tex]\sf \cfrac{(x+5)^2}{x+5}-\cfrac{x^2-6}{x-5}[/tex]
Now, cancel out x+5 in both numerator and denominator:-

Expand equations to make their denominators the same before adding or subtracting them. Multiply x+5 * x-5/x-5:-
[tex]\sf \cfrac{(x+5)(x-5)}{x-5}-\cfrac{x^2-6}{x-5}[/tex]
Now, Since [tex]\sf \frac{(x+5)(x-5)}{x-5}[/tex] and [tex]\sf \frac{x^2-6}{x-5}[/tex] and similar denominator, we'll subtrac their numerators.

Answers
Barbara's net loss on the sale of the stocks she purchased last year is 1245.63.
What is the net loss?A net loss is earned when the cost price of purchasing the stock is greater than the selling price.
Net loss = cost price - selling price
Cost price = 8500 + (8500 x 1.25%) = 8606.25
Selling price = 7324 + (7324 x 0.5%) = 7360.62
Net loss = 8606.25 - 7360.62 = 1245.63

Juan created 35 long swordsmen, 35 spearmen and 15 crossbowmen.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represnt the number of long swordsmen, y represent the spearmen and z represent the crossbowmen. Hence:
75x + 40y = 4025 (1)
25x + 40z = 1475 (2)
And:
30y + 30z = 1500 (3)

x = 35, y = 35 and z = 15

Prove that y=tan(mx) = sin(mx)/cos(mx)
Answers
The equation tan(mx) = sin(mx)/cos(mx) is a trigonometry equation
The trigonometry equation tan(mx) = sin(mx)/cos(mx) is true
How to prove the statement?The equation is given as:
tan(mx) = sin(mx)/cos(mx)
The tangent of an angle is the ratio of the sine and the cosine of the angle.
This means that:
tan(α) = sin(α)/cos(α)
By comparison, we have:
α = mx
Substitute α = mx in tan(α) = sin(α)/cos(α).
So, we have:
tan(mx) = sin(mx)/cos(mx)
Hence, the trigonometry equation tan(mx) = sin(mx)/cos(mx) is true

Hey there!
ORIGINAL QUESTION: “FINDING OUT WHATS EQUIVALENT TO 5/6”
We’re NOT sure what your equation should look like so we will make it like:
5/6 = z/6
CURRENT EQUATION:
5/6 = z/6
FIRST: CROSS MULTIPLY the NUMBERS
5(6) = z(6)
5(6) = 6(z)
NEW EQUATION (TEMPORARILY)
30 = 6z
6z = 30
DIVIDE 6 to BOTH SIDES
6z/6 = 30/6
CANCEL out: 6/6 because it give you 1
KEEP: 30/6 because it help solve for the z-value
NEW EQUATION: z = 30/6
SIMPLIFY IT!
z = 5
Thus, your answer is: 5/6 = 5/6
FUN FACT: THERE IS MULTIPLE FRACTIONS THAT ARE EQUIVALENT TO THE GIVEN FRACTION.
