<span>Simplifying 8k + 2m = 3m + k Reorder the terms: 8k + 2m = k + 3m Solving 8k + 2m = k + 3m Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-1k' to each side of the equation. 8k + -1k + 2m = k + -1k + 3m Combine like terms: 8k + -1k = 7k 7k + 2m = k + -1k + 3m Combine like terms: k + -1k = 0 7k + 2m = 0 + 3m 7k + 2m = 3m Add '-2m' to each side of the equation. 7k + 2m + -2m = 3m + -2m Combine like terms: 2m + -2m = 0 7k + 0 = 3m + -2m 7k = 3m + -2m Combine like terms: 3m + -2m = 1m 7k = 1m Divide each side by '7'. k = 0.1428571429m Simplifying k = 0.1428571429m</span>

According to the manufacturer, about 26% of sour candy in a package of Sandy's Sours are grape. What is the probability that the
Leto [7]

Answer:


Step-by-step explanation:

We assume that there are 100 sour candies, Thus-  

26 % of candy are grape implies that 26% of 100 candies are grape that is equal to 26

Now remaing candies that are not grape are 100-26 = 74

Based on the rule of multiplication:

P(A ∩ B) = P(A)/ P(B|A)  

 In the beginning, there are 26grape candies, probability of choosing first grape candy =  26C1 = 26

 After the first selection, we replace the selected grape candy so there are still 100 candies in the bag P(B|A) =  100C3 = 100 x 99 x 98 x 97!/3! X 97!

= 50 x 33 x 98

So probability =1/ 50 x 33 x 98 x 26

= 1/4204200

Brut [27]
2000 + 1500g ≤ 15000
1500g ≤ 15000 - 2000
1500g ≤ 13000
g ≤ 13000/1500
g ≤ 8 2/3

Therefore, the crane can safely lift a maximum of 8 2/3 cubic meters of gravel.
