A mango farm has 1250 mango trees......each tree produces 160 mangoes...so each farm produces : 1250 * 160 = 200,000 mangoes

g A visit to a hospital emergency room for something as simple as a sore throat could have a mean cost of $328. Assume that this
Rasek [7]

Answer:

The cut-off dollar amount is $328.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean cost of $328, standard deviation of $82.

This means that \mu = 328, \sigma = 82

If you want to be in the bottom 50%, what will be the cut-off dollar amount?

The 50th percentile, which is X when Z has a pvalue of 0.5. So X when Z = 0.

Z = \frac{X - \mu}{\sigma}

0 = \frac{X - 328}{82}

X - 328 = 0*82

X = 328

The cut-off dollar amount is $328.

What are the solutions of the quadratic equation (x + 3)2 = 49? x = –2 and x = –16 x = 2 and x = x = 4 and x = –10 x = 40 and x
steposvetlana [31]
Im gonna assume you are solving for x, the equation (x + 3)2 = 49 x is equal to 21.5 or 21 and 1/2. however the rest aren’t equations they’re just x = number and there isn’t much to do with that
