Americans who are 65 years of age or older make up 13.3% of the total population. If there are 30.7 million Americans in this age group, find the total U.S. population.
Tuntolu s mnulation is approximately million people.
Answer:
Step-by-step explanation:
13.3% of population = 30.7×10⁶
0.133 × population = 30.7×10⁶
population = 30.7×10⁶/0.133 ≅ 230.8×10⁶
population ≅ 230.8 million
The total U.S. population is approximately 23 million people.
Let the total population be T.Given the following data:

The price of a home is $300,000. After a 10% down payment, the mortgage is $270,000. If this is financed with a 30-year fixed-rate mortgage at 6%, what is the total interest paid over 30 year
Answer:
The correct solution is "$1618.79".
Step-by-step explanation:
The given values are:
Home price,
= $300,000
Down payment,
= 10%
Mortgage,
= $270,000
Rate,
r = 6%
Time,
t = 30 years
As we know,
⇒ [tex]PV=P[\frac{1-(1+r)^{-n}}{r} ][/tex]
On substituting the values, we get
⇒ [tex]270 000= P[\frac{1-(1+\frac{6}{1200} )^{-12\times 30}}{\frac{6}{1200} } ][/tex]
⇒ [tex]P=1618.79[/tex] ($)
Answer:
312,764.40
Step-by-step explanation:
We previously determined that you will make monthly payments of $1,618.79 for 30 years to pay off the loan. You are paying $1,618.79 per month for 360 months.
1,618.79×360−270,000=312,764.40
You are paying a total of $312,764.40 in interest over the life of the loan.
Which expression shows 3 2/5+(7 1/5) as a sum of integer and fractional parts?
Answer:
[tex]3+(-7)+\frac{2}{5}+(-\frac{1}{5})[/tex]
Step-by-step explanation:
We are given that an expression
[tex]3\frac{2}{5}+(-7\frac{1}{5})[/tex]
We have to find the expression which shows the sum of integer and fractional parts.
The given expression can be written as
[tex]3+\frac{2}{5}+(-7-\frac{1}{5})[/tex]
Now, adding integers
[tex](3+(-7)+\frac{2}{5}+(-\frac{1}{5})[/tex]
Now, adding fraction parts we get
[tex]3+(-7)+(\frac{2}{5}+(-\frac{1}{5}))[/tex]
Hence, the expression which shows the given expression as a sum of integers and fractional parts is given by
[tex]3+(-7)+\frac{2}{5}+(-\frac{1}{5})[/tex]
An aircraft flew 5 hours with the wind. The return trip took 6 hours against the wind. If the speed of the plane in still air is 260 miles per hour more than the speed of the wind, find the wind speed and the speed of the plane in still air.
I need this solved asap.
Answer:
Speed of wind = 23.63 miles per hour
Plane speed in still air = 260 miles per hour
Step-by-step explanation:
Given:
Time taken with wind = 5 hour
Time taken against wind = 6 hour
Assume;
Speed of wind = s
So,
Speed of Plane with wind = (260 + s) miles per hour
Speed of Plane against wind = (260 - s) miles per hour
Distance = speed x time
So,
(260 + s)5 = (260 - s)6
1,300 + 5s = 1,560 - 6s
11s = 260
s = 23.63 miles per hour
Speed of wind = 23.63 miles per hour
Plane speed in still air = 260 miles per hour

In American roulette, the wheel has the 38 numbers00, 0, 1, 2, ..., 34, 35, and 36 marked on equally spaced slots. If a player bets $1.00 on a number and wins, then the player keeps the dollar and receives an additional $35.00. Otherwise, the dollar is lost. Find the expected net gain to the player for one play of
Answer:
The expected net gain to the player for one play is -$0.0526.
Step-by-step explanation:
To find the expected net gain, we multiply each outcome by its probability:
Player wins:
Earns $35.
1 out of 38 numbers, so probability 1/38.
Player loses:
Loses $1.
37 out of 38 numbers, so probability 37/38.
Expected value:
[tex]\frac{1}{38} \times 35 - \frac{37}{38} \times 1 = -\frac{2}{38} = -0.0526[/tex]
The expected net gain to the player for one play is -$0.0526.
A group of 824 statistics students enrolled at a private 4-year university were asked to write down a random integer between 1 and 20. Very few people chose the number 1 (less than 1%.) The most common numbers were 7 (10%), 13 (11%), and 17 (13%.) How effective are students at generating random numbers
Answer:
Since the frequency of the numbers vary, the students are not effective at generating random numbers.
Step-by-step explanation:
If they were effective, all the numbers should have around the same probability of being generated.
Between 1 and 20 there are 20 numbers, so the frequency of each number should be around 100%/20 = 5%.
Since the frequency of the numbers vary, the students are not effective at generating random numbers.

solve the equation for z
5z-8=32
A. z=4
B. z=4.8
C. z=6
D. z=8
Answer:
Z=8 is the answer
Step-by-step explanation:
first, you add 8 to both sides which leaves you with 5z=40. then after that you divide both sides by 5 which leaves you with 5/5z = 40/5. then buy dividing 5 by 5 its leaves you with 1 which is equal to z because blank variables equal 1. On the other side if the equation 40 by 5 is 8 so that leaves you with z=8
Step-by-step explanation:
[tex] \tt{5z - 8 = 32}[/tex]
We want to remove the 8 first.
Step 1 : Since the original equation is minus 8 , we are going to use the opposite operation and add 8 to both sides.
⟶ [tex] \tt{5z - 8 + 8 = 32 + 8}[/tex]
Simplify -8 + 8 = 0 on the left. 32 + 8 = 40 on the right. Then we need to think about how to remove the coefficient 5.
⟶ [tex] \tt{5z = 40}[/tex]
Step 2 : Since the opposite of multiplication is division , we are going to divide both sides by 5.
⟶ [tex] \tt{ \frac{5z}{5} = \frac{40}{5}} [/tex]
Simplify. 5 / 5 = 1 on the left. 40/5 = 8 on the right. So , our answer is z = 8.
⟶ [tex] \tt{z = 8}[/tex]
[tex] \pink{ \boxed{ \boxed{ \text{Our \: final \: answer : \boxed{ \underline{ \tt{z = 8}}}}}}}[/tex]

The president of the student council wants to survey the student population about parking. She decides to use a random number table to take a random sample of 100 of the 1,020 students at the school. Refer to the given line from a random number table. Which numbers represent the first 2 students selected?
24000 75983 62200 91518 10198 88936
A.) 2400, 0759
B.) 2400, 8362
C.) 0759, 1518
D.) 0759, 1019
Answer:
C 0759, 1518
Step-by-step explanation:
The numbers which represent the first 2 students selected is the option D.) 0759, 1019.
What is Random Number Table?Random number table are a table of numbers arranged in an unpredictable sequence. These tables are used to select a random sample in certain situations.
We have the line in the random table as,
24000 75983 62200 91518 10198 88936
There are 1020 students in total.
So we have to select four digit numbers of the sequence 0001, 0002, ..........., 1019, 1020.
Any number which is not included in this interval will not be selected.
From the reference line given, the four digit numbers are,
2400, 0759, 8362, 2009, 1518, 1019, 8889, ...
From this line, mark the numbers included in our interval from 0001 to 1020.
The numbers are 0759 and 1019. Other numbers are not included in our required interval.
Hence the first 2 students will represent as the numbers 0759 and 1019.
