29.) This is simply interpreting the linear function.
The function:
96+2.1x
a.) The 96 is what you start with from the beginning. So, we know Rachel weighed 96 ounces when she was born.
b.) Again, interpretation. The 2.1 is the slope, or the change in the line. So we know that Rachel gains 2.1 ounces each day.
30.) For this one, you just have to plug 9 into the equation for x.

There are 60 office suites in a downtown building. For how many office suites does company C service the computers? -Company A s
natima [27]
Company C services 16 office suites.

Company A services 1/3 of the suites and Company B services 2/5; together they service 1/3+2/5.  Find a common denominator; 15 is the smallest:

1/3=5/15
2/5=6/15

5/15+6/15 = 11/15

This means that 1-11/15 = 4/15 of the suites are serviced by Company C.

4/15 of 60 = 4/15(60) = 4/15(60/1) = 240/15 = 16

Find the Z-scores that separate the middle 61% of the distribution from the area in the tails of the standard normal distributio
professor190 [17]

Answer:

Z-scores between -0.86 and 0.86 separate the middle 61% of the distribution from the area in the tails of the standard normal distribution

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.

Middle 61%

Between the 50 - (61/2) = 19.5th percentile and the 50 + (61/2) = 80.5th percentile.

19.5th percentile.

Z with a pvalue of 0.195. So Z = -0.86

80.5th percentile.

Z with a pvalue of 0.805. So Z = 0.86.

Z-scores between -0.86 and 0.86 separate the middle 61% of the distribution from the area in the tails of the standard normal distribution
