<u>The correct answers are:</u>
$47.50;
$24.25;
$5.75;
$123.03;
$18;
$59;
Home by $7.50; and 
separate rentals.

Explanation:
<u><em>For the first question:</em></u>
Your family purchases 2 adult tickets at $8 each; 2*8=16.  You then purchase 1 10-18 ticket for $7.25 and 1 under 10 ticket for $4.25.  You then purchase $20 in soda and popcorn.  This gives us a total of:

16+7.25+4.25+20=47.50.

<u><em>For the second question:</em></u>
You purchase your ticket for 7.25 and a ticket for each of your siblings at 4.25, which is 2*4.25=8.50.  You then purchase $10 in soda and popcorn.  This gives us a total of:

7.25+8.50+10=25.75.

The change will be:
50-25.75=24.25.

<u><em>For the third question:</em></u>
5 tickets at $16.85 each would be 5*16.85=84.25.

This gives us
90-84.25=5.75 in change.

<u><em>For the fourth question:</em></u>
7 tickets at $13.79 each will cost 7*13.79=96.53.

The handling for all 7 tickets, at $2.50 each, will be 7*2.50=17.50

These together with the shipping charge will be
96.53+17.50+9=$123.03.

<u><em>For the fifth question:</em></u>
The book of 8 tickets, which cost $5.25 each, will be 8*5.25=$42.

This will give us
60-42=$18 in change.

<u><em>For the sixth question:</em></u>
He has buy one get one free tickets; this means he will buy 3 tickets and get 3 free for the first 6 tickets. He will then need to buy the 7th ticket; this means he will pay for 4 tickets:
4*10.25=$41.

Out of $100, he will have 
100-41=$59 in change.

<u><em>For the seventh question:</em></u>
The tickets at Theatre Y cost 8.25*2=16.50.  Two drink/popcorn combos at the theatre will cost 4.50*2=9.  Together, this is 16.50+9=25.50.

The cost of the dvd rental (4.50), soda (1.50) and popcorn (2.00) at home is 4.50+1.50+2=8.  This makes staying at home the cheaper option; it is 
25.50-8=$17.50 cheaper.

<u><em>For the eighth question:</em></u>
4 separate rentals will cost 4*3.99=$15.96.  This is cheaper than $20.

uppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.2 and a standard deviation of 1.49. Us
liubo4ka [24]

Answer:

99.85% of American women have shoe sizes that are less than 12.67

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 8.2

Standard deviation = 1.49

Using the empirical rule, what percentage of American women have shoe sizes that are less than 12.67

12.67 = 8.2 + 3*1.49

12.67 is 3 standard deviations above the mean.

Since the normal distribution is symmetric, 50% of the measures are below the mean and 50% are above. Of those 50% above, 99.7% are between the mean and 12.67. So

0.5 + 0.997*0.5 = 0.9985

99.85% of American women have shoe sizes that are less than 12.67

The mass of an electron is approximately 9.11 × 10 -28 grams. Find the mass of 401,000,000 electrons. 3.65311 × 10-19 grams 3.65
NNADVOKAT [17]

Answer:

Total\ Mass = 3.65311 * 10^{-19} grams

Step-by-step explanation:

Given

Mass = 9.11 * 10^{-28}g

Required

Determine the mass of 401,000,000 electrons

To do this, we simply multiply the mass of 1 electron by the number of electrons.

This gives:

Total\ Mass = 401,000,000 * 9.11 * 10^{-28}

Total\ Mass = 3653110000 * 10^{-28}

Express 3653110000 as a standard form

Total\ Mass = 3.65311 * 10^9 * 10^{-28}

Apply law of indices:

Total\ Mass = 3.65311 * 10^{9-28}

Total\ Mass = 3.65311 * 10^{-19}

Hence, the mass of 401000000 electrons is 3.65311 * 10^{-19}\ grams
