Using the binomial probability relation ; the probability that an head is obtained at least 50 times is 0.0271
Using the binomial probability relation :
P(x = x) = nCx * p^x * q^(n-x) p = probability of success = 0.4q = 1 - p = 0.6n = number of trials = 100P(x ≥ 50) = p(x = 50) + p(x = 51) + ...+ p(x = 100)
Using a binomial probability calculator :
P(x ≥ 100) = 0.0271
Therefore, the probability that atleast 50 heads are obtained in the trial is 0.0271

Paloma evaluated the expression 1 3/4 − 5/8. What is a way she can check her work?
9514 1404 393
Answer:
add the subtrahend to the difference
Step-by-step explanation:
The usual way to check a subtraction problem is to add the subtrahend to the difference to see if you get the minuend as a result.
Paloma can add 5/8 to her result to see if she gets 1 3/4.
__
She can also perform the subtraction using decimal fractions to see if she gets the same result.

Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 5 hours. Together they charged a total of $950. What was the rate charged per hour by each mechanic if the sum of the two rates was $125 per hour?
Answer:
First mechanic: $65.
Second mechanic: $60.
Step-by-step explanation:
Let the rates be x for the first mechanic and y for the second.
x + y = 125
10x + 5y = 950
Multiply first equation by - 5
-5x - 5y = -625
Adding the last 2 equations:
5x = 325
x = 65
y = 125-65 = 60 .

Answer:
x = 45
Step-by-step explanation:
180-136 = 44
x - 1 = 44
x = 44 + 1
x = 45
x = 45°
Step-by-step explanation:
The two angles are supplementary so
[tex]136° + (x-1) = 180°[/tex]
[tex]\Rightarrow x - 1 = 44°[/tex]
or
[tex]x = 45°[/tex]

Se le conoce como medidas o parámetros que se sitúan hacia el centro de un conjunto de valores,
con el objetivo de analizar un análisis profundo de los resultados
Las medidas o parámetros que se sitúan hacia el centro de un conjunto de valores, con el objetivo de analizar un análisis profundo de los resultados, son denominadas "medidas de tendencia central".
Una medida de tendencia central da una impresión del centro de una cantidad de datos o una distribución. Dependiendo de la medida de centro utilizada, el centro puede significar el centro de los datos o la distribución, o el lugar más probable donde se encuentran la mayoría de los datos.
Por tanto, una medida de centro da una impresión de los datos o la distribución en un número y, a veces, también se utiliza como un resumen de un solo número de los datos o la distribución. Las medidas conocidas del centro son la media aritmética y geométrica, la mediana, la moda y el centro del rango (el valor exactamente entre los valores mínimo y máximo).

Answer:
4294967296 Kilograms
Step-by-step explanation:
Great Pyramid has 2^21 blocks
2^21 = 2097152, so
2097152 blocks
Blocks weigh 2^11 each
2^11 - 2048, so
2048 kg per block
2097152(number of blocks) x 2048(weight in kilograms per block) = The Great Pyramid in Egypt weighs 4294967296 Kilograms
Step-by-step explanation:
More than 2,300,000 limestone and granite blocks were pushed, pulled, and dragged into place on the Great Pyramid. The average weight of a block is about 2.3 metric tons (2.5 tons).
How much is that? Well, you can think of it in terms of refrigerators. An average refrigerator weighs about 91 kg. If 1 metric ton = 1,000 kg, how many refrigerators equal a 2.3-metric ton block?
A 25 refrigerators
B 5 refrigerators
C 90 refrigerators

A sports tournament has b teams. Each team has 8 players. Using b, write an expression for the total numbers of players in the tournament.
Answer:
The answer is 8b
Step-by-step explanation:
Hey, a variable is a filler for an unknown number. Don't let it confuse you too much!
If there were 5 teams, there would be 8(5) = 40 players, right??
With b teams, there are 8b players. We are lazy as mathematicians and don't say 8(b) or 8 x b. It's just 8b.
Thus, The answer is 8b

An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. The drain pipe can be used to empty the pool in 34 hours. If the pool is [tex]\frac{2}{3}[/tex] filled and then the inlet pipe and drain pipe are opened, how many more hours would it take to fill the pool? Round your answer to two decimal places, if needed.
Answer:
374 hoursStep-by-step explanation:
Filling rate is 1/33Draining rate is 1/34The difference is the filling rate with both lines open:

Answer:
-3 ≤ x ≤ 19/3
Step-by-step explanation:
This inequality can be resolved to a compound inequality:
-7 ≤ (3x -5)/2 ≤ 7
Multiply all parts by 2.
-14 ≤ 3x -5 ≤ 14
Add 5 to all parts.
-9 ≤ 3x ≤ 19
Divide all parts by 3.
-3 ≤ x ≤ 19/3
_____
Additional comment
If you subtract 7 from both sides of the given inequality, it becomes ...
|(3x -5)/2| -7 ≤ 0
Then you're looking for the values of x that bound the region where the graph is below the x-axis. Those are shown in the attachment. For graphing purposes, I find this comparison to zero works well.
__
For an algebraic solution, I like the compound inequality method shown above. That only works well when the inequality is of the form ...
|f(x)| < (some number) . . . . or ≤
If the inequality symbol points away from the absolute value expression, or if the (some number) expression involves the variable, then it is probably better to write the inequality in two parts with appropriate domain specifications:
|f(x)| > g(x) ⇒ f(x) > g(x) for f(x) > 0; or -f(x) > g(x) for f(x) < 0
Any solutions to these inequalities must respect their domains.

The Blazers hockey team has won 5 of its first 12 games. No game was tied. The Rockets’ record is 5 wins and 3 losses. Which team has the better record?
help please
Answer:
The Rockets' team has the better record.
Step-by-step explanation:
The Blazers hockey team has played 12 games but they won only 7 out of the 12 games, so that means that they loss the other 5 games. So that makes the Blazers record 7 wins and 5 losses.
The Rockets' team has played 8 games but they won only 5 out of the 8 games, so that means that they loss the other 3 games. So that makes the Rockets' record 5 wins and 3 losses.
So, the Rockets' team has the better record because they loss less games than the Blazers team did.

2) A pool is being filled with a hose. The equation y=12x represents the relationship between
the number of gallons of water in the pool (y) and the number of minutes the water runs (X). If
this relationship is represented on a graph, which ordered pair would not lie on the line?
NEED HELPS ASAP PLS AND THANK U
Answer:
D)
Step-by-step explanation:
y = 12x.
A) x=8, so that y = 12(8) = 96. It's on the line
B) x = 10, so that y = 12(10) = 120. It's on the line
C) x = 15, so that y = 15(12) = 180. It's on the line
D) x = 18, so that y = 18(12) = 216, not equal to 206. So, the point is not on the line.
