D. Mrs. Buchanan decided to throw her daughter a sweet sixteen party. She rented a room at a local venue for $500 a night plus $

8 per person. If the bill was $1140, how many people attended the party? Mrs. Miller wants to buy a snake that costs $242. She already has $62 and she plans to save $12 per week. In how many weeks will she have enough money to buy the snake?​

Answer:

1) 80 people  2) 15 weeks

Step-by-step explanation:

(x = the number of people)

500 + 8x = 1140  ← ($500 initially plus $8 per person equals $1140)

8x = 640 ←(subtract the $500 from each side)

x = 80 ←(divide by the $8 per person to get the number of people)

------

(x = the number of weeks)

242 = 62 + 12x  ←(The cost of the snake ($242) is equal to her $62 plus $12 she saves every week)

180 = 12x  ←(subtract the $62 from both sides)

15 = x  ←(divide by the $12 per week)

The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. So therefore, the numbers would be 2 and 4.

Assume adults have IQ scores that are normally distributed with a mean of 102 and standard deviation of 16. Find the probability
Andre45 [30]

Answer:

57.49% probability that a randomly selected individual has an IQ between 81 and 109

Step-by-step explanation:

When the distribution is normal, we use 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 question, we have that:

\mu = 102, \sigma = 16

Find the probability that a randomly selected individual has an IQ between 81 and 109

This is the pvalue of Z when X = 109 subtracted by the pvalue of Z when X = 81. So

X = 109

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

Z = \frac{109 - 102}{16}

Z = 0.44

Z = 0.44 has a pvalue of 0.67

X = 81

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

Z = \frac{81 - 102}{16}

Z = -1.31

Z = -1.31 has a pvalue of 0.0951

0.67 - 0.0951 = 0.5749

57.49% probability that a randomly selected individual has an IQ between 81 and 109

B, because 10 is a multiple of 5, so anything divided by 10 could be divided by 5 (sort of how any even number can be divided by 2)
