G) 1/12
♡ Step-by-step explanation ♡
In order to figure out this problem, we have to take a few relatively simple steps.
First, we must count the total number of coins in the cash register. Do not change the value of these coins. Simply take the numbers listed in the problem and add them up. Your process for completing this step should look something like this: 10+11+13+6 equals 40. With this being said, there are 40 coins in the cash register.
Next, we must remember the values of the two coins the question is asking for: pennies and dimes. Keep in mind that, out of all 40 coins, 10 of them are pennies and 13 of them are dimes.
Then, we write the fractions used to find the answer to this problem. In the question, the cashier (hypothetically) draws a penny first, and then a dime. This means a penny is drawn before a dime is drawn. (Although it seems like a miniscule detail, this knowledge is actually something extremely important to remember. This small piece of information can actually change the entire answer if not used properly.)
In this problem, the cashier would choose a single penny out of the 10 in contrast to the total 40 coins. Since there are 10 pennies overall, and 40 coins overall, the probability of choosing a penny first is 10/40.
After we complete the probability of choosing a penny before all else, we must find the probability of choosing a dime after choosing a penny. Since the dime will be chosen after the penny is chosen, one coin will be gone: the chosen penny. So, the total amount of coins within the cash register changes (or more specifically decreases (by 1)) from 40 to 39. However, the amount of dimes, 13, stays the same. With this information in mind, we can write a fraction of 13/39 for the probability of choosing a dime after choosing a penny.
Finally, now that we have both probability fractions, we can figure out the answer to the question. In order to do this, we multiply and simplify both fractions. 10/40*13/39 is 130/1560. 130 ÷ 130 is 1. 1560 ÷ 130 is 12. 1 ÷ 12 can also be written as 1/12. Therefore, the answer to this problem is G) 1/12.
(The paragraph and author's note below are technically optional thought processes and information, but read them if you wish. Although I would recommend reading further, considering another way to solve the question is mentioned, it is entirely you (the reader's) choice.)
You can also check this answer through the other/alternate way of solving this problem: by simplifying both probability fractions before you multiply them. 10/40 can be simplified to 1/4. 13/39 can be simplified to 1/3. After doing this, we multiply both simplified probability fractions in order to find, or in this case check, the answer. 1/4*1/3 is 1/12. 1/12 is the same fraction as the one present in choice G. This is the same answer as the one we previously got. This enforces the idea that G) 1/12 is indeed the answer to this question.
A/N (Author's Note): Although it took quite a while to jot down, this was truly a blast to write and explain! I hope this helped those that needed/wanted it. Have a wonderful week reader(s)!

Workers install 840 chairs at a constant rate. After 8 days, the workers still have to install 360 chairs. How much time does it take to install the chairs from start to finish?
It took them 4 days to install 480 chairs which means if they were working at a constant rate they got 120 chairs installed daily. with 360 chairs left that means in 3 days they will finish. so overall, it took the workers 7 days to finish, or a week.

A company has borrowed $50000 at 10% compounded quarterly. The debt is amortized by equal payment each quarter ove 15 years. Find the quarterly payments and how much interest will be paid?
7500000 is interest will pay quarterly .
What do compound and simple interest mean?
Simple Interest is the amount returned for using the borrowed funds over a predetermined amount of time. When the total principal amount surpasses the payment due date and the interest rate over a certain period of time, this is known as compound interest. S.I. = (P, T, and R) x 100 is the formula.p = $50000
r = 10%
t = 15 years
interest = 50000 * 10 * 15 /100
= 7500000

If the mean span of automobile tires is 34000 miles and standard deviation is 2350 miles then the z scores that corresponds to the life spans of sample showing 33000 miles,37000 miles and 32000 miles are -0.4255, 1.2766 and -2.1277.
Given that mean span of automobile tire is 34000 miles and standard deviation is 2350 miles.
We are required to find the z score of the sample of 33,000 miles, 37,000 miles, and 32,000 miles.
A z-score basically gives us an idea of how far from the mean a data point is.
Z=(X-μ)/σ
In our case we have to find the mean of life span of three samples.
For the life span of 33000 miles,
Z=(33000-34000)/2350
=-1000/2350
=-0.4255
For the life span of 37000 miles,
Z=(37000-34000)/2350
=3000/2350
=1.2766
For the life span of 32000 miles,
Z=(32000-37000)/2350
=-5000/2350
=-2.1277
Hence if the mean span of automobile tires is 34000 miles and standard deviation is 2350 miles then the z scores that corresponds to the life spans of sample showing 33000 miles,37000 miles and 32000 miles are -0.4255, 1.2766 and -2.1277.

A linear function has the equation 4x+6y= 50. What is the
value of a when y = 3?
x =
Answer: x=8
Step-by-step explanation:
4x+6y=50
4x+6(3)=50
4x+18=50
4x=32
x=8
The value of x when y = 3 in the linear function 4x + 6y = 50 is x = 8.
Use the concept of linear fucntion defined as:
The formula for a linear function is f(x) = mx + b, where m and b are real values. The slope-intercept form of a line is represented by the equation,
y = mx + b.
The given linear fucntion is:
4x+6y= 50
To find the value of x when y = 3,
Substitute y with 3 in the equation and solve for x.
4x + 6(3) = 50
4x + 18 = 50
To isolate x,
Subtract 18 from both sides:
4x = 50 - 18
4x = 32
Now we divide both sides by 4:
x = 32/4
x = 8
Hence,
When y = 3, the value of x in the linear function 4x + 6y = 50 is 8.

On being asked her age, Shalu replies, 'My brother was born 2 years before me and my sister 4 years after me, and the sum of their ages is 30 years." How old is Shalu?
Shalu is 16 years old.
The equation can be defined as a mathematical term that refers to a situation in which several factors must be considered. It is defined as the state of being equal and is frequently represented as a math expression with equal numbers on either side.
Two expressions joined by an equal sign form a mathematical statement known as an equation.
Shalu's brother was born 2 years before Shalu.
Shalu's sister was born 4 years after Shalu.
And the sum of Shalu's brother and sister's age is 30 years.
Let x be the age of Shalu.
As Shalu's brother was born 2 years before her = x + 2
As Shalu's sister was born 4 years after her = x - 4.
Therefore,
x + 2 + x - 4 = 30
2x - 2 = 30
Adding 2 on each side of the equation,
2x -2 + 2 = 30 + 2
2x = 32
Dividing each side of the equation by 2.
2x / 2 = 32 / 2
x = 16
Therefore, Shalu is 16 years old.

WHAT IS DERIVATIVE?The derivative is what calculus is all about. The instantaneous pace at which a function changes with regard to one of its variables is known as the derivative. Finding the slope of the tangent line to the function at a given point is equal to doing this.
CALCULATIONf'(x) = d/dx ( 4 e^sin(x))
using differential rule d/dx (a x f ) = a x d/dx(f)
f'(x) = 4 x d/dx ( e ^ sin(x))
use the chain rule
f'(x)= 4 x d/dg ( e^g) x d/dx (sin (x))
f'(x)= 4 e^g x d/dx (sin (x))
