The total number of cans in the display is 611.
What is the total number of cans in display?Let's denote the number of cans in the first row as x.
According to the problem statement, each subsequent row has 5 fewer cans than the row beneath it.
Therefore, the number of cans in the second row will be x - 5, the number of cans in the third row will be x - 10, and so on.
We are given that there are 13 rows in total, and the top row has 1 can. Therefore, we can write the following equation:
x + (x - 5) + (x - 10) + ... + (x - 60) + (x - 65) = 1 + 2 + 3 + ... + 12 + 13
Simplifying the left-hand side, we can combine like terms:
13x - (5 + 10 + 15 + ... + 60 + 65) = 91
Using the formula for the sum of an arithmetic series, we can evaluate the sum of the numbers in parentheses:
5 + 10 + 15 + ... + 60 + 65 = (13/2)(5 + 65) = 455
Substituting this value into the equation, we get:
13x - 455 = 91
Solving for x, we find that:
x = 46
Therefore, the number of cans in each row is:
46, 41, 36, ..., 1
To find the total number of cans, we can use the formula for the sum of an arithmetic series:
n/2(a + l)
where;
n is the number of terms, a is the first term, and l is the last term.In this case, n = 13, a = 46, and l = 1. Plugging in these values, we get:
13/2 x (46 + 1) = 13/2 x 47 = 611.5
Since we can't have a fraction of a can, the total number of cans in the display is 611.

Joan’s finishing time for the Bolder Boulder 10k race was 1.84 standard deviations faster than women’s average for her age group There were 395 women who ran in her age group assuming a normal distribution how many women ran faster than Joan(round down your answer to the nearest whole number)
Rounding down to the nearest whole number, we can conclude that about 12 women in her age group ran faster than Joan.
What is a whole number?A whole number is a number that is not a fraction, decimal or negative. Whole numbers include all positive integers (1, 2, 3, ...), as well as zero (0). They are also sometimes referred to as counting numbers, as they are commonly used for counting objects or items.
What is standard normal distribution?A standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1. It is a specific type of normal distribution that has been standardized to have these specific parameters, which makes it easier to calculate probabilities and perform statistical analyses.
In the given question,
We can use the standard normal distribution to solve this problem. Since Joan's finishing time was 1.84 standard deviations faster than the mean for her age group, we know that her finishing time is in the top (100% - 1.84% = 98.16%) of the distribution.
To find the number of women who ran faster than Joan, we need to find the area under the standard normal distribution curve to the right of her z-score. Using a standard normal distribution table or calculator, we can find that the area to the right of a z-score of 1.84 is 0.0322.
Therefore, approximately 395 x 0.0322 = 12.729 women in Joan's age group ran faster than her. Rounding down to the nearest whole number, we can conclude that about 12 women in her age group ran faster than Joan.

c) The probability event that sum is 6 in case of both dice are 4 -sided is equals to the 3/16.
d) The probability event that sum is 6 in case of one die is 4 -sided and one is 6 sided is equals to 5/24.
There are five fair dice in my pocket, three are 4-sided and two are 6-sided. Randomly select two of the dice, roll them, and record the sum. We have to determine the probabilities for different events. First, When two six-sided dice are rolled, total possible outcomes = 36
= {1,2,3,4,5,6}{1,2,3,4,5,6}
Similarly, When two four-sided dice are rolled, total possible outcomes = 16 = {1,2,3,4}{1,2,3,4}
Also, when one 4-sided and othe 6-sided faire dice are rolled, total possible outcomes = 24 = {1,2,3,4 } {1,2,3,4,5,6}
a) Let the event for sum is 6 be 'E'. The probability the sum is 6, P(E) = 5/36 + 3/16 + 5/24 = ( 20 + 27 + 30)/144
= 77/144
b) The probability that sum of the dice is 6 for both dice are 6 -sided = 5/36
c) Possible outcomes of occurrence of event E in case of both dice are 4 -sided = 3
The probability of occurrence of event E in case of both dice are 4 -sided, P(E)
= 3/16
d) Possible outcomes of occurrence of event E in case of one die is 4 -sided and one is 6 sided = 5
The probability one die is 4 -sided and one is 6 sided = 5/24
Hence, required probability is 5/24.

signing bonus.
• B. Hunter's wage is $35 an hour, and it appears that he received a
signing bonus of $25.
O C. Hunter's wage is $25 an hour, but it appears that he received no
signing bonus.
• D. Hunter's wage is $25 an hour, and it appears that he received a
signing bonus of $35.
Answer: C
Step-by-step explanation:
The correct answer is C.
The slope of the line represents the hourly wage, so Hunter's wage is $35 an hour, as given in option A and B. However, the y-intercept of the line represents the starting pay or the pay for zero hours worked. In this case, the y-intercept is 25, which means Hunter received $25 even if he did not work any hours. Hence, option C is correct as it states that Hunter's wage is $25 an hour, but it appears that he received no signing bonus.

T/F. Star clusters with lots of bright, blue stars of spectral type O and B are generally younger than clusters that don't have any such stars.
The given statement "Star clusters with lots of bright, blue stars of spectral type O and B are generally younger than clusters that don't have any such stars." is True. The reason for this is that O and B stars are short-lived and burn through their fuel quickly.
The reason for this is that O and B stars burn through their fuel quickly, causing them to exhaust their nuclear fuel and end their lives in a relatively short period, typically within a few tens of millions of years.
On the other hand, stars of lower mass and cooler temperatures, like G and K type stars like our sun, have longer lifetimes and take billions of years to exhaust their nuclear fuel.
Therefore, clusters without any bright, blue stars are likely to have evolved for longer periods, allowing these short-lived stars to have already expired.

The linear sf of two similar shapes is 2:5 if the area of the similar shapes is 78cm determine the area of the bigger solid
The area of the bigger solid is 67.24 cm².
How to calculate the area of solid ?Assume the smaller shape has a length of 2x and a width of 2y. The larger shape would then have 5x length and 5y width.
Because the area of a rectangle is the product of its length and width, the area of the smaller shape is:
Area of smaller shape = 2x * 2y = 4xy
We know that the similar shapes have an area of 78 cm2. As a result, we can write:
4xy + larger area = 78
(larger shape area) / (smaller shape area) = (linear scale factor)²
Substituting the values from the problem yields:
(larger shape area) / (4xy) = (5/2)2 = 25/4
When we multiply both sides by 4xy, we get:
larger shape area = (25/4) * 4xy = 25xy
Now we can plug the expression we discovered for the area of the smaller shape into the equation we found earlier:
4xy + 25xy = 78
29xy = 78
xy = 78/29
Substituting this xy value into the expression we discovered for the area of the larger shape yields:
larger shape area = 25xy = 25 * (78/29) = 67.24 cm2 (rounded to two decimal places)
As a result, the larger shape has an area of approximately 67.24 cm2.

d)Rana and Sophie each plan to bike 3 hours tomorrow . How much farther will Sophie bike than Rana
Answer: I got you!
Step-by-step explanation:
a) Sophie's distance is given by the formula: distance = rate × time. Therefore, her distance yesterday is s × t miles.
b) Rana's time is given by the formula: time = distance ÷ rate. Therefore, her time yesterday is m ÷ r hours.
c) Sophie's time is given by the formula: time = distance ÷ rate. Let's call the time Sophie waits for Rana "w". Then we have two equations:
Sophie's distance: s × (w + t) = 20
Rana's distance: r × (w + t) = 20 - m
We can solve for "w" by substituting the second equation into the first equation:
s × (w + t) = 20 - r × (w + t) + m
(s + r) × (w + t) = 20 + m
w + t = (20 + m) ÷ (s + r)
w = (20 + m) ÷ (s + r) - t
Therefore, Sophie waits for Rana for (20 + m) ÷ (s + r) - t hours.
d) Sophie's distance tomorrow is s × 3 miles, and Rana's distance tomorrow is r × 3 miles. Therefore, the difference in distance is (s - r) × 3 miles.

Answer:
The total labor charges for the job are P3,500.
Step-by-step explanation:
To find the total labor charges for a job that takes 2 1/2 hours, we need to look at the labor charges for each hour and a half-hour fraction and add them up.
For the first hour, the charges are P1,200. For the second hour, the charges are P1,400. For the third hour (the half-hour fraction), the charges are P1,800 / 2 = P900.
So, the total labor charges for 2 1/2 hours of work are
P1,200 + P1,400 + P900 = P3,500
Therefore, the total labor charges for the job are P3,500.

The area is multiplied by 1/16 and the correct option is (a) The area is multiplied by 1/16.
When the radius of a circle is multiplied by 1/4, the effect on the area can be calculated using the formula A = πr², where A is the area and r is the radius. The new radius becomes (1/4)r, so the new area can be calculated by substituting (1/4)r for r in the original formula. Simplifying this expression, we get A' = π((1/4)r)² = (1/16)πr². This shows that the area is multiplied by 1/16, so the correct answer is (a) The area is multiplied by 1/16.

Which mapping does not represent a function?
Answer: C
Step-by-step explanation:
For any function, a value plugged in (x) cannot have more than 1 outcome (y). C states that when x = 10, y has 2 values; 30 and 35. This means C is not a function.
Give an example to show that if d is not prime and n2 is divisible by d, then n need not be divisible by d.
If d is not a prime number and n^2 is divisible by d, it does not necessarily mean that n is also divisible by d, example is d = 6 and n = 3, where n^2 = 9 is divisible by 6, but n = 3 is not divisible by 6.
A prime number is a positive integer greater than 1 that has exactly two distinct factors: 1 and itself. For example, 2, 3, 5, 7, 11, 13, and 17 are all prime numbers.
If a number d is not prime, then it has at least one factor other than 1 and itself. Let's assume that d is not prime, and let p be a factor of d such that p is not equal to 1 or d. Then, by definition, p divides d evenly with no remainder.
Consider the case where d = 6 and n = 3.
Here, d is not a prime number, and n^2 = 9, which is divisible by d since 9 is a multiple of 6. However, n = 3 is not divisible by d = 6, as 6 does not divide 3 evenly.
