The weight of bags of coffee beans at the grocery store follows a Normal distribution with a mean of μ = 7 ounces and a standard deviation of σ = 2 ounces. Suppose we pick four bags of coffee beans at random from the shelf and find their total weight, W. Which of the following statements describes the random variable W?
A. The random variable W is Normal, with a mean of seven ounces and a standard deviation of two ounces.
B. The random variable W is Normal, with a mean of 28 ounces and a standard deviation of 16 ounces.
C. The random variable W is Normal, with a mean of 28 ounces and a standard deviation of four ounces.
D. The random variable W is binomial, with a mean of 28 ounces and a standard deviation of four ounces.
E. The random variable W is binomial, with a mean of seven ounces and a standard deviation of two ounces.
Answer:
C.
Step-by-step explanation:
The random variable W is Normal, with a mean of 28 ounces and a standard deviation of four ounces.
mean of total = 7+7+7+7 = 28
Variance of total = 4+4+4+4 = 16
SD of total = sqrt(16) = 4

Answer:
1/16
Step-by-step explanation:
Find the common denominator between 3/4, 1/8, and 1/16. 3/4 and 1/8 denominator can be 16. Then we have to make their denominator the same so multiply 3/4 with 4/4 and multiply 1/8 with 2/2:
3/4 + 1/8 + 1/16 = 12/16 + 2/16 + 1/16 = 15/16
now canola oil is the only thing left to find so that means:
16/16 - 15/16 = 1/16

En un distrito, hay una calle peatonal. El municipio decidió colocar faroles, bancas y sembrar árboles para mejorar el ornamento. Los faroles serán colocados cada 30 metros, las bancas cada 20 metros y los árboles serán sembrados cada 50 metros. ¿Cada cuántos metros volverán a coincidir un farol, una banca y un árbol?
Answer:
El lugar donde la linterna, los bancos y los árboles se encuentran nuevamente está a 300 metros del punto de inicio.
Step-by-step explanation:
Los parámetros dados son;
El espacio entre las linternas = 30 metros.
El espacio entre los bancos = 20 metros.
El espacio entre los árboles = 50 metros.
Por lo tanto, tenemos, la ubicación donde la linterna, los bancos y los árboles se encuentran nuevamente, está dada por el mínimo común múltiplo de cada una de sus distancias de separación individuales como sigue;
2 divide 30 20 50 [tex]{}[/tex]
[tex]{}[/tex] 5 divide 15 10 25
[tex]{}[/tex] 3 2 5
El LCM = 2 × 5 × 3 × 2 × 5 = 300
El lugar donde la linterna, los bancos y los árboles se vuelven a encontrar está a 300 metros del punto de inicio.

What is 7/12+5/6?
Add the fractions, please
Answer:
1 5/12
Step-by-step explanation:
first we have to convert the denominator(bottom number) to 12
6x2=12
Now we have to multiple 2 to the numerator(top number)
since we have to do the same to the top and bottom
5x2=10
now we add the fractions
7/12+ 10/12=17/12
now we simplify the fraction
17/12= 1 5/12
hopefully you understand how to do it.

Ms. Hamm bought a new car for $37,500. It is said that her car depreciates at a rate of 7% each year
Answer:
This would mean that the next year her car's value would go down by $2,625. The new value of the car would consequently be $34,875.
Step-by-step explanation:Here is how you can solve this problem:
Okay, so first, let's find 7% of $37,500. To do this, the simple way would be to find first 1% of $37,500. 1% of $37,500 is $375. This is because you are moving the decimal point two spaces to the left.Now that we know that 1% of $37,500 is $375, let's multiply this value by 7.
375 x 7 = 2625.Subtract 2625 from 37,500.You will get $34,875.Let's say that the next year, her car value goes down by 7% again.
THIS IS THE IMPORTANT PART:
YOU FIND 7% OF THE NEW VALUE, NOT $37,500. YOU WOULD FIND 7% OF $34,875.
Hope this helps! :)
What is the end behaviour of this radical function?
[tex] f(x) = - 2 \sqrt[3]{x + 7} [/tex]
Answer: The square root function f(x)=√x has domain [0,+∞) and the end behaviour is. as x→0 , f(x)→0. as x→∞ , f(x)→∞. Note: "end behavior"
Step-by-step explanation:
So, the sign of the leading coefficient is sufficient to predict the end behavior of the function. To predict the end-behavior of a polynomial function, first check whether the function is odd-degree or even-degree function and whether the leading coefficient is positive or negative.
The end behavior of the function is, when x approaches positive infinity, f(x) approaches negative infinity.
Option A is correct.
End behavior of function:We have to find the end behavior of the given radical function.
To check end behavior, we have to check limit of function at x tends to infinity and x tends to minus infinity.
Given function are,
[tex]f(x)=-2\sqrt[3]{x+7}[/tex]
We can not put [tex]x=-\infty[/tex], because variable under square root must be greater than equal to zero.
When we check limit at [tex]x=\infty[/tex].
[tex]\lim_{x \to \infty} f(x)= \lim_{x \to \infty} -2\sqrt[3]{x+7}=-\infty[/tex]
Hence, the end behavior of the function is, when x approaches positive infinity, f(x) approaches negative infinity.
