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?
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

While playing a real-time strategy game, Juan created military units for battle: long swordsmen, spearmen, and crossbowmen.
Long swordsmen require 75 units of food and 25 units of gold. Spearmen require 40 units of food and 30 units of wood.
Crossbowmen require 30 units of wood and 40 units of gold. If Juan used 1475 units of gold, 1500 units of wood, and 4025 units
of food to create the units, how many of each type of military unit did he create?
Juan created
long swordsmen.
Parti
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)
Hence;
x = 35, y = 35 and z = 15
Juan created 35 long swordsmen, 35 spearmen and 15 crossbowmen.

The difference between the squares of two numbers is 15. Three times the square of the first number increased by the square of the second number is 49. Find the numbers
Answer: 256,1
Step-by-step explanation:
[tex]\sqrt{x} - \sqrt{y} =15\\\sqrt{y} = 49-3\sqrt{x} \\\\\sqrt{x} -(49-3\sqrt{x} ) =15 \\so, x=256\\substitute \{x}\ :\\\\\sqrt{y} = 49-3\sqrt{256} =y=1[/tex]
so, 256=x
and, y=1

Answer:
1, 4 or -1, -4
Step-by-step explanation:
Let the two numbers be x and such that x > y.
According to the first condition:
[tex]x^2 -y^2= 15[/tex]
[tex]\implies x^2 =y^2+15[/tex]......(1)
According to the second condition:
[tex]3x^2 +y^2= 49[/tex]
[tex]\implies 3(y^2+15) +y^2= 49[/tex]
(From equation 1)
[tex]\implies 3y^2+45 +y^2= 49[/tex]
[tex]\implies 4y^2 =49-45[/tex]
[tex]\implies 4y^2 =4[/tex]
[tex]\implies y^2 =\frac{4}{4}[/tex]
[tex]\implies y^2 =1[/tex]
[tex]\implies y =\pm 1[/tex]
When y = 1
[tex]\implies x^2 =(1)^2+15=1+15=16[/tex]
[tex]\implies x =\pm 4[/tex]
When y = -1
[tex]\implies x^2 =(-1)^2+15=1+15=16[/tex]
[tex]\implies x =\pm 4[/tex]
Thus, the required numbers are either 1, 4 or -1, -4

The answer would be ⁻[tex]\frac{19}{x-5\\}[/tex]
Answer:
[tex]\underline{\boxed{\sf \cfrac{-19}{x-5}}}[/tex]
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:-
[tex]\sf x+5-\cfrac{x^2-6}{x-5}[/tex]
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.
[tex]\sf \cfrac{(x+5)(x-5)-(x^2-6)}{x-5}[/tex]
[tex]\sf \cfrac{x^2-5x+5x-25-x^2+6}{x-5}[/tex]
Combine like tems in [tex]\sf x^2-5x+5x-25-x^2+6[/tex] :-
[tex]\sf \cfrac{-19}{x-5}[/tex]

given f(x)= 8x+1/2x-9 what is the end behaviors of the function
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

barbara purchased stock last year for 8500 and paid a 1.25% broker fee. she sold it for 7324 and had to pay a .5% broker fee.
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

Find the number of permutations of the letters of the word LOOPHOLE
Answer:
6!/3!=6x5x4x3x2/3x2=6x5x4=120
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

1 yard (yd) = 3 feet (ft); 1 foot (ft) = 12 inches (in) how many inches are there in 5 yards?
Answer: 180 inches
Step-by-step explanation:
We can use dimensional analysis. Our desired units are inches per yard. Begin by writing down:
[tex]\frac{12in}{1ft}[/tex]
Then use the conversion factor of feet to yard. The units of feet will cancel giving:
[tex]\frac{12in}{1ft} *\frac{3ft}{1yd}=\frac{36in}{1yd}[/tex]
Multiply the top and bottom by 5 to get:
[tex]\frac{36in}{1yd} *\frac{5}{5} =\frac{180in}{5yd}[/tex]

Prove that y=tan(mx) = sin(mx)/cos(mx)
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
