The last digit of the product is 5.
How did we get the value?To find the last digit of the product of these numbers, we only need to focus on the last digit of each number, since the other digits do not affect the last digit of the product. We can observe that every odd number has a last digit of 1, 3, 5, 7, or 9. Therefore, we only need to consider the last digit of every fifth odd number in the given sequence.
The last digit of 2001 is 1.
The last digit of 2003 is 3.
The last digit of 2005 is 5.
The last digit of 2007 is 7.
The last digit of 2009 is 9.
The last digit of 2011 is 1.
The last digit of 2013 is 3.
The last digit of 2015 is 5.
The last digit of 2017 is 7.
The last digit of 2019 is 9.
To find the last digit of the product of these numbers, we need to multiply all of these last digits together. We can group the digits into pairs that multiply to 1, and there is one 5 remaining. Multiplying all of these digits together gives:
1 * 3 * 5 * 7 * 9 * 1 * 3 * 5 * 7 * 9 * 5 = 5
Therefore, the last digit of the product is 5.

8.2 A sum of R45 360 has to be shared among three people. Divide the money between Ayanda, (4 Zipho and Palesa according to the ratio of 4:3:2
Answer:
Ayanda will receive R20,160, Zipho will receive R15,120, and Palesa will receive R10,080.
Step-by-step explanation:
We can use the ratio of 4:3:2 to find the total number of parts:
4 + 3 + 2 = 9
This means that the money will be divided into 9 equal parts, and Ayanda will get 4 parts, Zipho will get 3 parts, and Palesa will get 2 parts.
To find the value of one part, we divide the total amount by 9:
45,360 / 9 = 5,040
Therefore, one part is worth R5,040.
Now we can find the amount of money each person will receive by multiplying their respective parts by the value of one part:
Ayanda: 4 parts × R5,040/part = R20,160
Zipho: 3 parts × R5,040/part = R15,120
Palesa: 2 parts × R5,040/part = R10,080
Therefore, Ayanda will receive R20,160, Zipho will receive R15,120, and Palesa will receive R10,080.

A company sells doughnuts. They incur a fixed cost of $25,000 for rent, insurance, and other expenses. It costs $0.25 to produce each doughnut. Let x = number of doughnut produced. Find the Variable cost.
The variable cost for x doughnuts produced is 0.25x.
What is variable cost?
Costs that vary according on how much of an item or service a company produces are known as variable costs.
The fixed cost for the company is $25,000, which is a constant amount that does not depend on the number of doughnuts produced. The variable cost, on the other hand, is the cost that varies with the number of doughnuts produced.
Since it costs $0.25 to produce each doughnut, the variable cost for x doughnuts can be calculated as 0.25x.
Therefore, the variable cost for x doughnuts produced is 0.25x.

x = ?
Answer:
x = 12
Step-by-step explanation:
96 / 24 = 4, 28/ 7 = 4, assuming that it dilated by 4, so use 4 to multiply 25, 4 x 25 = 100 so 6x+28 = 100 then plug it in 6(12) + 28 = 100., 100 = 100
To check use a^2 + b^2 = c^2
28^2 + 96^2 = (6(12)+28)^2
784 + 9216 = (72+28)^2
784 + 9216 = 100^2
784 + 9216 = 10000
10000 = 10000
2. The mean age of a family of seven is 23 years. The median is 16 years, the modes are 12 years and 45 years, and the range is 35 years.
a. Find the ages of the seven family members.
b. Give a scenario that would result in the two given modes.
Let the 7 letters A through G represent the ages of the 7 person family.
A = youngest age = minG = oldest age = max7/2 = 3.5 which rounds to 4 represents the slot number of the median, aka the middle-most position. The 4th letter is D. Because the median is 16, we know that D = 16.
We go from this
A,B,C, D, E,F,G
to this
A,B,C, 16, E,F,G
I put a bit of spacing to help show why D is the middle.
-------------------
The modes are 12 and 45, which means those values show up more than once. Let's assume they show up 3 times each.
That tells us A,B, and C are all equal to 12. Furthermore, that assumption indicates E,F,G are all equal to 45.
We go from this
A,B,C, 16, E,F,G
to this
12,12,12, 16, 45,45,45
But we run into a problem. The range is max-min = 45-12 = 33 and not 35 like we want.
We have no choice but to remove one copy of "12" and remove one copy of "45". We need to remove both because removing only one of those would result in the mode being just one value (rather than two).
-------------------
So we have this now
A,12,12, 16, 45,45,G
where A < 12 and G > 45
range = max - min = G-A = 35
G-A = 35 solves to G = 35+A
We can update the set to
A,12,12, 16, 45,45,35+A
-------------------
Now to figure out what "A" is.
The bit of info we haven't used yet is the mean.
Recall the mean has us add up the numbers and then divide by the number of values.
mean = (sum of the values)/(number of values)
mean = (A+B+C+D+E+F+G)/7
mean = (A+12+12+16+45+45+35+A)/7
mean = (2A+165)/7
Set that equal to the stated mean of 23 so we can solve for "A".
mean = (2A+165)/7
(2A+165)/7 = 23
2A+165 = 7*23
2A+165 = 161
2A = 161-165
2A = -4
A = -4/2
A = -2
That's not good. We should have gotten a positive whole number for "A". Since "A" is negative, it means there is a typo somewhere in the given instructions.
It's impossible to have a family of 7 people where the mean age is 23, the median is 16, the modes are 12 and 45, and the range is 35. At least one of those starting values needs to change. If for instance the "45"s were changed to "41", then the equation above would solve to A = 2.

About how many years will it take for Arthur’s investment to double?
Responses
A.7.73 years
B.7.79 years
C.7.87 years
D.8.04 years
Answer:
Step-by-step explanation:
We can use the rule of 72 to estimate the time it takes for Arthur's investment to double. The rule of 72 states that the time it takes for an investment to double is approximately 72 divided by the annual rate of return.
To apply this rule, we need to calculate the annual rate of return that Arthur is earning on his investment. We can do this by calculating the percentage increase in his account balance from year to year.
From year 1 to year 2, his account balance increased by (118.81 - 109)/109 = 9.81/109 = 0.09 = 9%.
From year 2 to year 3, his account balance increased by (129.5 - 118.81)/118.81 = 10.69/118.81 = 0.09 = 9%.
So the average annual rate of return over this period is approximately 9%. Using the rule of 72, we can estimate that it will take approximately 72/9 = 8 years for Arthur's investment to double.
Therefore, the closest option among the given responses is option D. It will take about 8.04 years for Arthur's investment to double.

The prove that triangle ABE is congruent to triangle CDE is given below
What is congruence?Generally, To prove that triangle ABE is congruent to triangle CDE, we need to show that they have the same size and shape.
First, we can see that angle AED and angle CEB are opposite angles and therefore congruent, since AB || DC.
Also, since line AB = line DC, we know that segment AE is congruent to segment CE and segment BE is congruent to segment DE.
Using these congruent sides and the congruent angle, we can apply the Side-Angle-Side (SAS) congruence criterion to conclude that triangle ABE is congruent to triangle CDE.
Therefore, we have proven that triangle ABE is congruent to triangle CDE.

Find the center and radius of the circle represented by the equation below.
x^2+y^2-8x-20y+52=0
Answer:
Step-by-step explanation:
To find the center and radius of the circle represented by the equation:
x^2 + y^2 - 8x - 20y + 52 = 0
We can start by completing the square for both x and y terms as follows:
(x^2 - 8x) + (y^2 - 20y) + 52 = 0
(x^2 - 8x + 16) + (y^2 - 20y + 100) + 52 = 16 + 100
(x - 4)^2 + (y - 10)^2 = 64
Thus, the equation can be rewritten in the standard form of the circle as:
(x - 4)^2 + (y - 10)^2 = 8^2
Therefore, the center of the circle is (4, 10), and its radius is 8 units.
Step-by-step explanation:
x² + y² - 8x - 20y + 52 = 0
the standard circle equation is
(x - h)² + (y - k)² = r²
where (h, k) is the center of the circle, and r is the radius.
now, we need to find the squared terms in the original equation.
x² and y² are clearly from the (x - h)² and (y - k)².
and then
(x - h)² = x² - 2hx + h²
-2hx = -8x
2h = 8
h = 4
(y - k)² = y² - 2ky + k²
-2ky = -20y
2k = 20
k = 10
h² + k² = 16 + 100 = 116
116 - r² = 52
r² = 64
r = 8
so, the center is (4, 10), the radius is 8.
Where would a person experience the least atmospheric pressure?
A. An altitude exactly at sea level
B. An altitude of 1 km below sea level
C. An altitude of 7 km above sea level
D. An altitude of 1 km above sea level
Answer: The atmospheric pressure decreases with altitude. This is because as we move higher above the earth's surface, there is less air above us and therefore less weight pushing down on us. Therefore, the correct answer is:
C. An altitude of 7 km above sea level
At an altitude of 7 km above sea level, a person would experience the least atmospheric pressure because they would be furthest from the earth's surface and there would be very little air above them. This is why the air pressure in the Earth's upper atmosphere is much lower than at the surface of the Earth.

A campus radio station surveyed 500 students to determine the types of music they like. The survey revealed that 204 like rock,164 like country, and 129 like jazz. Moreover, 24 like rock and country, 29 like rock and jazz, 29 like country and jazz, and 9 like all three types of music. How many students surveyed liked exactly one of the three types of music? (Note: A Venn diagram may be useful here.)
a) 200
b) 500
c) 140
d) 360
e) 9
Answer:
d) 360
Step-by-step explanation:
To solve this problem, we can use a Venn diagram. Let R, C, and J represent the sets of students who like rock, country, and jazz, respectively. We can fill in the diagram with the given information:
J
/ \
/ \
/ \
RC-----C
\ /
\ /
\ /
R
We know that:
The total number of students surveyed is 500.
9 students like all three types of music, so we can put 9 in the intersection of all three sets (RCJ).
24 like rock and country, so we can put 24 in the intersection of R and C (RC).
29 like rock and jazz, so we can put 29 in the intersection of R and J (RJ).
29 like country and jazz, so we can put 29 in the intersection of C and J (CJ).
We can calculate the number of students who like only one type of music by subtracting the number of students who like two or three types of music from the total number of students surveyed:
Total = R + C + J - RCJ
500 = 204 + 164 + 129 - 9
We can use this equation to solve for R, C, and J:
R = 204 - 24 - 29 - 9 = 142
C = 164 - 24 - 29 - 9 = 102
J = 129 - 29 - 29 - 9 = 62
So there are 142 students who like rock only, 102 students who like country only, and 62 students who like jazz only. Therefore, the total number of students who like exactly one type of music is:
142 + 102 + 62 = 306
Therefore, the answer is (d) 360.

The answer is C) 18/48 and 21/56.
Step-by-step explanation:Two ratios are proportional if they have the same ratio when simplified to lowest terms.
A) 7/10 and 10/10 cannot be proportional because 7/10 cannot be simplified further, while 10/10 simplifies to 1/1.
B) To simplify the first ratio, we can divide both the numerator and denominator by 4, giving us 5/7. To simplify the second ratio, we can divide both the numerator and denominator by 3, giving us 5/6. Since these simplified ratios are not equal, the two ratios are not proportional.
C) To simplify the first ratio, we can divide both the numerator and denominator by 6, giving us 3/8. To simplify the second ratio, we can divide both the numerator and denominator by 7, giving us 3/8. Since these simplified ratios are equal, the two ratios are proportional.
D) To simplify the first ratio, we can multiply both the numerator and denominator by 2, giving us 6/10, which simplifies to 3/5. The second ratio is already in simplified form. Since these simplified ratios are not equal, the two ratios are not proportional.

Air pressure decreases during a storm. The difference between the normal air pressure 'n' and the air pressure during the 1935 Florida Keys hurricane was greater than 121 millibars.
Write an inequality that could be used to find the normal air pressure in the Florida Keys before the hurricane?
Answer:
Step-by-step explanation:
Let's assume that the normal air pressure in the Florida Keys before the hurricane is represented by the variable 'p'. The inequality that could be used to find 'p' based on the given information is:
p - 121 > n
This inequality states that the difference between the normal air pressure 'p' and the air pressure during the hurricane ('n') is greater than 121 millibars. By rearranging this inequality, we can solve for 'p':
p > n + 121
Therefore, the normal air pressure in the Florida Keys before the hurricane was greater than the air pressure during the hurricane plus 121 millibars.

Total number of video games sold on Friday and Saturday = 3,878 + 8,999 = 12,877
Total number of video games sold over the three days = (number sold on Friday) + (number sold on Saturday) + (number sold on Sunday)
We know that the total number of video games sold over the three days is the sum of the number sold on Friday and Saturday plus the number sold on Sunday. We can rearrange this equation to solve for the number sold on Sunday:
Number sold on Sunday = Total number sold over three days - Number sold on Friday and Saturday
Substituting in the values we know, we get:
Number sold on Sunday = (number sold on Friday) + (number sold on Saturday) + (number sold on Sunday) - (number sold on Friday) - (number sold on Saturday)
Number sold on Sunday = Total number sold over three days - Number sold on Friday and Saturday
Number sold on Sunday = (3,878 + 8,999 + X) - 12,877
Number sold on Sunday = X - 0
Simplifying this expression, we get:
Number sold on Sunday = 6,000
Therefore, Cloey sold 6,000 video games on Sunday.
65% of the people in Missouri pass the driver’s test on the first attempt. A group of 5 people took the test. What is the probability that less than 3 in the group pass their driver's tests in their first attempt?
Round your answer to three decimal places.
Remember: 65% = 0.65.
Answer:
Step-by-step explanation:
This problem involves a binomial distribution where the probability of success (passing on the first attempt) is 0.65, and the probability of failure (not passing on the first attempt) is 0.35. We want to find the probability that less than 3 out of 5 people pass on their first attempt.
We can use the binomial probability formula to calculate this:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)
Where X is the number of people who pass on their first attempt.
P(X = 0) = (5 choose 0) * 0.65^0 * 0.35^5 = 0.0024
P(X = 1) = (5 choose 1) * 0.65^1 * 0.35^4 = 0.0289
P(X = 2) = (5 choose 2) * 0.65^2 * 0.35^3 = 0.1323
So,
P(X < 3) = 0.0024 + 0.0289 + 0.1323 = 0.1636
Therefore, the probability that less than 3 out of 5 people pass their driver's tests on the first attempt is approximately 0.164, rounded to three decimal places.
the price of petrol increased from R12,58 per litre to R13,28 per litre. Determine the percentage increase in the price
Therefore, the percentage increase in the price of petrol is approximately 5.57%.
What percentages were converted?One tenth of any amount is represented by the relative number 10% in the image. Since one percent (1%) represents the one tenth of something, 100 percent (100%) denotes the entire thing, and 200 percent (200%) denotes twice the amount indicated. percentage. Mathematical percentile is a similar subject.
To find the percentage increase in the price of petrol, we can use the formula:
percentage increase = (new value - old value) / old value x 100%
Here, the old value is R12.58 per litre, and the new value is R13.28 per litre. Substituting these values into the formula, we get:
percentage increase = (13.28 - 12.58) / 12.58 x 100%
percentage increase = 0.70 / 12.58 x 100%
percentage increase = 0.0557 x 100%
percentage increase = 5.57%
Therefore, the percentage increase in the price of petrol is approximately 5.57%.

Suppose you have an outstanding balance of $400 on your credit card, which has a 15%
APR. You have carefully considered your budget and decided that you can afford to pay
$75 per month until the balance is paid in full. You have also decided that you will not
make any additional purchases using the card.
4
Assuming that the card compounds daily, what will the balance be after the first payment
at the end of the first month?
Answer:
The first step is to calculate the daily interest rate. We can do this by dividing the annual percentage rate (APR) by 365 (the number of days in a year):
Daily interest rate = 15% / 365 = 0.00041096
Next, we need to calculate the interest that accrues on the outstanding balance for the first month. Since there are 30 days in a typical month, we can multiply the daily interest rate by the outstanding balance and the number of days in the month:
Interest for first month = 0.00041096 × $400 × 30 = $4.93
This means that the outstanding balance after the first payment will be:
$400 + $4.93 - $75 = $329.93
So the balance after the first payment will be $329.93.
