Using it's concept, it is found that there is a 0.25 = 25% probability of obtaining a prime number and a head.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
For the dice, 3 out of 6 outcomes are prime(2, 3 and 5), hence P(A) = 3/6 = 0.5.For the coin, 1 out of 2 outcomes is heads, hence P(A) = 1/2 = 0.5.The events are independent, hence the probability of both is given by:
P(A and B) = P(A) x P(B) = 0.5 x 0.5 = 0.25.
0.25 = 25% probability of obtaining a prime number and a head.

95 students choose to attend one of three after school activities: footbal,l tennis or running. There are 28 boys. 38 students choose football, of which 26 are girls. 23 students choose tennis. 29 girls choose running. A student is selected at random. What is the probability this student choose running? Give your answer in its simplest form.
Answer:
34/95
Step-by-step explanation:
Since 38 students choose football and 23 students chose tennis, then 95 - 38 - 23 = 34 students chose running. The probability is 34 / 95.

Since 64 is a perfect cube ³√64 = 4
and the exponents 27 and 125 are also perfect cubes ³√27= 3 and ³√ 125 = 5 respectively.
Answer:
D.
Step-by-step explanation:
64 = 4³
x^(27) = (x^3)^3
y^(125) = y^(5*5*5) =(y^5)^3
D. 64x^(27)y^(125) = (4x^3 y^5)^3
Triangle J L N is cut by line segment K M. LIne segment K M goes from side J L to side L N. The length of J K is 10, the length of K L is 16, the length of L M is 24, and the length of M N is 15. Is KM ∥ JN? Why or why not? No, because StartFraction 16 Over 10 EndFraction not-equals StartFraction 24 Over 15 EndFraction. Yes, because StartFraction 10 Over 24 EndFraction equals StartFraction 15 Over 16 EndFraction. Yes, because StartFraction 16 Over 10 EndFraction equals StartFraction 15 Over 24 EndFraction Yes, because StartFraction 16 Over 10 EndFraction equals StartFraction 24 Over 15 EndFraction.
Answer:
D. Yes, because StartFraction 16 Over 10 EndFraction equals StartFraction 24 Over 15 EndFraction.
Step-by-step explanation:
When two line are parallel, they do not meet even with continuous extension of their length.
In the given triangle JLN, line segment KM would be parallel to side JN if;
[tex]\frac{KL}{JK}[/tex] = [tex]\frac{LM}{MN}[/tex]
Given that: KL = 16, JK = 10, LM = 24 and MN = 15.
⇒ [tex]\frac{16}{10}[/tex] = [tex]\frac{24}{15}[/tex]
[tex]\frac{8}{5}[/tex] = [tex]\frac{8}{5}[/tex]
Therefore, since the ratios are the same then KM ∥ JN. So that the statement; Yes, because [tex]\frac{16}{10}[/tex] equals [tex]\frac{24}{15}[/tex] is correct.

The answer is D on edge.

HELP ITS ABOUT POINTS AND EQUATIONS AND WHAT THE PERSON FAILED IN DOING EXPLANATION NEEDED PLEASE
Answer:
see below
Step-by-step explanation:
First find the slope
m= ( y2-y1)/(x2-x1)
= (-5- -7.5)/ ( 2 - -3)
= (-5+7.5) / ( 2+3)
= 2.5 /5
=1/2
Then using the slope intercept equation of a line
y = mx+b where m is the slope and b is the y intercept
y = 1/2x+b
Using a point from above
-5 = 1/2(2) +b
-5 =1+b
Subtract 1 from each side
-6 = b
We have the y intercept
y = 1/2x-6
Tahlia forget to find the y intercept for the equation
Answer:
y = 0.5x - 6
Step-by-step explanation:
(-3. -7.5) ; (2 , -5)
[tex]Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-5-[-7.5]}{2-[-3]}\\\\=\frac{-5+7.5}{2+3}\\\\=\frac{2.5}{5}\\\\=0.5[/tex]
m = 0.5 ; (2, -5)
equation of line : y-y1 = m(x-x1}
y -[-5]=0.5(x - 2)
y + 5 = 0.5x - 0.5*2
y + 5 = 0.5x - 1
y = 0.5x - 1 -5
y = 0.5x - 6

Miguel is playing a game in which a box contains four chips with numbers written on them. Two of the chips have the number 1, one chip has the number 3, and the other chip has the number 5. Miguel must choose two chips, and if both chips have the same number, he wins $2. If the two chips he chooses have different numbers, he loses $1 (–$1). Let X = the amount of money Miguel will receive or owe. Fill out the missing values in the table. (Hint: The total possible outcomes are six because there are four chips and you are choosing two of them.) Xi 2 –1 P(xi) What is Miguel’s expected value from playing the game?
Answer:
The answer is "[tex]\bold{-\frac{1}{2}}[/tex]"
Step-by-step explanation:
Miguel's choose the best way to win the 2 dollars by pulling the two chips with the number 1. In total, there are four balls, so his probability of winning is:
[tex]\to \frac{2}{4} \times \frac{1}{3}= \frac{1}{6}[/tex]
The chances of losing a dollar add up to that amount, so 5/6.
Price predicted = [tex]\frac{1}{6} \times (2) + \frac{5}{6} \times (-1)[/tex]
[tex]=\frac{1}{6} \times 2 + \frac{5}{6} \times -1\\\\=\frac{1}{3} - \frac{5}{6} \\\\=\frac{2-5}{6}\\\\=\frac{-3}{6}\\\\=- \frac{1}{2}\\[/tex]
The final answer is "[tex]-\frac{1}{2}[/tex]"

Solve the simultaneous equations
4x + 3y = 21
and
4x + 2y = 16
Answer:
x = 3/2 y=5
Step-by-step explanation:
4x + 3y = 21
4x + 2y = 16
Subtract the two equations
4x + 3y = 21
-4x - 2y = -16
-----------------------
y = 5
Now find x
4x+3y = 21
4x +3(5) = 2a
4x+15 = 21
Subtract 15
4x = 6
Divide by 4
4x/4 = 6/4
x =3/2
Tenía 5.00 $ que mi mamá me dio 10.00 $, mientras que mi papá me dio 30.00 $ y mi tía y mi tío me dieron 100.00 $ y yo tenía otros 5.00 $, cuánto dinero hizo Realmente lo tengo?
Responder:
$ 150Explicación paso a paso:
Si inicialmente tengo $ 5 y mi madre me dio $ 10, el dinero total inicial que tengo será $ 5 + $ 10 = $ 15
Si mi papá me dio $ 30, mi tía y mi tío me dan $ 100, el monto recibido de mi tía y mi tío será de $ 30 + $ 100, es decir, $ 130
Como tengo otros $ 5 para todo este dinero, el dinero que realmente tengo será la suma total de todo el dinero recibido más mi dinero personal.
Dinero que realmente tengo = $ 15 + $ 130 + $ 5
= $ 150
El problema de palabras con la suma puede ser bastante complicado si no se maneja con cuidado. Para resolverlo y comprenderlo mejor, enumeremos los parámetros de la información proporcionada:
Tenía = $5.00Su mamá le dio = $10.00Papá le dio = $30.00Su tía y su tío le dieron = $ 100.00 (esto implica que tanto su tía como su tío le dieron $ 100.00 ya que no especificaron que es individualConcluye diciendo que tenía otros $ 5.Entonces, la cantidad total de dinero que tiene es la suma del dinero que recibió de los miembros de su familia con la cantidad de dinero que tenía con él.
Para determinar eso, tendremos que sumar todas las cantidades.
i.e.
= $(5.00 + 10.00 + 30.00 + 100.00 + 5.00)
= $150.00
Por tanto, podemos concluir que la cantidad total que realmente tiene es $150.00

find the smallest square number that is divisible by each of the number 8,12,18 and 30
Answer:
3600.
Step-by-step explanation:
8 = 2*2*2
12= 2*3
18= 2*3*3
30 = 2*3*5
The lowest common multiple of the these is
2 * 2 * 2 * 3*3* 5 = 360.
So the smallest square number = 2*2*2*2*3*3*5*5
(We make all the sets of factors a square).
So it's 16 * 9 * 25 = 3600.
