Answer:
A) x=39
Step-by-step explanation:
117 = 3x
117 divided by 3 = 39
3x = 117
3(39) = 117
117 = 117
A) x = 39
Answer:
$460
Step-by-step explanation:
let the number of melons be x
4x + 3x + 3x = 200 melons
10x = 200 so, x will be 20
4x = 80 melons
3x = 60
3x = 60
amount made by 1st child = 80 × $2 = 160$
the remaining melons are 60 + 60 = 120
amount collected: they sold them in groups of 2 and each group was $5. so,
120÷2 × $5 = $300
total amount = 300 + 160 = $460.

Answer:
True
Step-by-step explanation:
Point estimation of a population parameter provides an estimate of a single value calculated from the sample that is likely to be close to its value to the unknown parameter. Itis to be noted that a point estimate will not in general be equal to the population parameter as the random sample used is one of the many possible samples which could be chosen from the population.
For example, in estimation, we may estimate the mean and the variance of a population by computing the mean and the variance of the sample drawn from a population.
