Arlecino [84]2 years ago
8 0

Answer:

3 \frac{13}{44}

Step-by-step explanation:

First let's write our equation

13  \frac{9}{10}  \div 3  \frac{1}{2}

Now let's make them improper fractions

\frac{139}{10}  \div  \frac{7}{2}

Now since we're dividing we with fractions we do the reciprocal and multiply

\frac{139}{10}  \times  \frac{2}{7}

or

\frac{139}{5}  \times  \frac{1}{7}  =  \frac{139}{42}  = 3 \frac{13}{42}

According to the National Vital Statistics, full-term babies' birth weights are Normally distributed with a mean of 7.5 pounds a
Sav [38]

Answer:

68.26% probability that a randomly selected full-term pregnancy baby's birth weight is between 6.4 and 8.6 pounds

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 7.5, \sigma = 1.1

What is the probability that a randomly selected full-term pregnancy baby's birth weight is between 6.4 and 8.6 pounds

This is the pvalue of Z when X = 8.6 subtracted by the pvalue of Z when X = 6.4. So

X = 8.6

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

Z = \frac{8.6 - 7.5}{1.1}

Z = 1

Z = 1 has a pvalue of 0.8413

X = 6.4

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

Z = \frac{6.4 - 7.5}{1.1}

Z = -1

Z = -1 has a pvalue of 0.1587

0.8413 - 0.1587 = 0.6826

68.26% probability that a randomly selected full-term pregnancy baby's birth weight is between 6.4 and 8.6 pounds

If 5 to the power of 4 m =5 to the power of 12, what is the value of m​
skelet666 [1.2K]

Answer:

the answer would be three because when an exponent is on the inside of the parenthesis and one is outside too, then they are multiplied. If it wasn't, then it would be added.

Given an actual demand of 64, a previous forecast of 59, and an of .3, what would the forecast for the next period be using simp
BartSMP [9]

Answer: 60.5

Step-by-step explanation:

The forecast for the next period using the simple exponential smoothing method is given by:

D\times \alpha+F(1-\alpha) , where D= actual demand for the recent period, \alpha= smoothing factor, F= forecast for the recent period .

Given: D= 64, \alpha=0.34 , F= 59

The forecast for the next period  = 64\times0.3+59(1-0.3)

\\\\= 64\times0.3+59\times0.7\\\\=19.2+41.3\\\\=60.5

Hence, the forecast for the next period = 60.5
