Answer:

33.33%

Step-by-step explanation:

78x = 52

52/78 = x

0.6667 = x

to get this as a percentage, multiply 0.6667 by 100 to get 66.67%

this is the discounted percentage but to get the discount percent, you subtract 100 by this percentage to get 33.33% off

The weight, X, of cherry tomatoes selected at random from a very large bin at the local supermarket follows a Normal distributio
Vesna [10]

Answer: the probability that exactly 5 of the 8 cherry tomatoes weigh less than 4 oz is 0.05

Step-by-step explanation:

Given that;

X has normal distribution has mean µ = 3

standard deviation σ = 2  

now

P( x< 4) = P( (x-µ)/σ /(3-4)/5)

= P( z < -0.5 )

= 0.3085  {from the z-table}

X has binomial distribution with n = 8 and p = 0.3085

so P(x=5)

P(x=5) = 8C₅(0.3085)⁵ (1 - 0.3085)⁸⁻⁵

= 0.0517  ≈ 0.05

Therefore the probability that exactly 5 of the 8 cherry tomatoes weigh less than 4 oz is 0.05
