If a random sample of size n = 43 is drawn, find μx, σ x and p(28 ≤ x ≤ 30). (round σx to two decimal places and the probability to four decimal places.)

How to solve a simultaneous equation involved with fractions?

Problem situation: caren is making rice and beans. she can spend no more than $10 on ingredients. she buys one bag of rice for $4.99. beans cost $0.74 per pound. how many pounds of beans, x, can she buy? inequality that represents this situation: 10≥4.99+0.74x drag each number to show if it is a solution to both the inequality and the problem situation, to the inequality only, or if it is not a solution.
