Probability that you will role an even number on the first roll: 3 even / 6 total = 3/6 chance = 1/2 chance
probability that you role a number greater than 4 on the second: only numbers greater than 4 are 5 and 6, so you have 2 numbers / 6 total = 2/6 chance = 1/3 chance
because it says AND, you have to multiply the first role probability by the second role probability
so 1/2 x 1/3 = 1/6
answer: 1/6
Answer:
The cost to rent a snorkel is 9$
(<em>espanol</em>) el costo de un snorkel es de 9$
Step-by-step explanation:
(English)Given that the group of tourists have spent $153 in renting snorkels and fins and there are 12 snorkels and 15 pairs of fins being rented, allow x to be the amount paid for the rent of the snorkels and y to be the rent for pairs of fins then 12x + 15y = 153. Given also that the rent for a snorkel is three times the rent of a pair of fins then x = 3y then, 12(3y) + 15y = 153. Simplify the equation, 36y + 15y = 153. 51y = 153. Solve for y by dividing both sides of the equation by 51 then, y = 153/51 = 3. Therefore, renting a pair of fins costs $3. To compute for the rent of a snorkel, use the equation x = 3y then, x = 3($3) = $9.
(Espanol) Dado que el grupo de turistas han gastado $153 en el alquiler de snorkels y aletas y hay 12 snorkels y 15 pares de aletas que se alquilan, permitir x para ser la cantidad pagada por el alquiler de los snorkels y y para ser el alquiler para pares de aletas entonces 12x + 15y 153. Dado también que el alquiler para un snorkel es tres veces el alquiler de un par de aletas y luego x a 3y, entonces, 12 (3y) + 15y a 153. Simplifique la ecuación, 36y + 15y a 153. 51y a 153. Resuelva para y dividiendo ambos lados de la ecuación por 51 entonces, y á 153/51 a 3. Por lo tanto, alquilar un par de aletas cuesta $3. Para calcular el alquiler de un snorkel, utilice la ecuación x á 3y, a continuación, x a 3($3) a $9.

To get the number of factors, simply take each item from the expression and isolate it. Given the formatting limitations, I can't write the factor 2 over 5 and will instead represent it as 2/5.
So the expression is
2/5ab
where there's an implied multiplication between all the factors. Making that multiplication explicit, the equation becomes
2/5 * a * b
And each possible factor also becomes quite explicit. Namely, the factors are
2/5
a
b
The reason that the 2 and 5 aren't considered factors is because technically, you could consider the 2 to be a factor, there isn't a corresponding factor of 1/5. So you have to consider 2/5 to be a single entity.</span>
The median is 50, answer B. It is the middle number of the data set so it is the median. If there are an even set of numbers, so obviously there will be two numbers in the middle, then you simply need to add them and divide by two. Hope this helps! :)
Answer:
97.5 miles
Step-by-step explanation:
=65mi=60 min
All you need to do is add half of 65
=65+32.5
=97.5 miles
So therefore in 90 minutes you would drive 97.5 miles
