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

The solutions to the quadratic equation are:
x = (-9 + 3√(5)) / 2 or x = (-9 - 3√(5)) / 2
Option A is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
Quadratic equation x² + 9x + 9 = 0.
a = 1, b = 9 and c = 9
We can use the quadratic formula.
x = (-b ± √(b^2 - 4ac)) / 2a
where a, b, and c are the coefficients of the quadratic equation.
Now,
Plugging in the given values.
x = (-9 ± √(9^2 - 4(1)(9))) / 2(1)
Simplifying.
x = (-9 ± √(81 - 36)) / 2
x = (-9 ± √(45)) / 2
x = (-9 ± 3√(5)) / 2
Therefore,
The solutions to the quadratic equation x^2 + 9x + 9 = 0 are:
x = (-9 + 3√(5)) / 2 or x = (-9 - 3√(5)) / 2

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

Malawi exports approximately 1 × 10 3 metric tons of coffee per year, and Venezuela exports approximately 3 × 10 4 metric tons of coffee per year. Approximately how many times greater is Venezuela's coffee export amount than Malawi's?
Answer:
Venezuela's export of coffee is 30 times greater than Malawi's.
Step-by-step explanation:
Malawi's exports = 1 × 10³ = = 1 × (10 × 10 × 10) = 1 × 1000 = 1000 metric tons
Venezuela's exports = 3 × 10⁴ = 3 × (10 × 10 × 10 × 10) = 1 × 10,000 = 30,000 metric tons
To find by how many times greater is Venezuela's coffee export amount than Malawi's, we will divide the former by the later.
[tex]\frac{Venezuels's\ export}{Malawi's\ export} = \frac{30,000}{1000} = 30[/tex]
Therefore, Venezuela's export of coffee is 30 times greater than Malawi's.

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! :)

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

4x+y=6
y=-4x-1
HELP ME
Answer:
No solutionStep-by-step explanation:
Given
4x+y=6 y=-4x-1Solution 1Substitute y in the first equation:
4x + (-4x - 1) = 64x - 4x =6 + 10 = 7Incorrect, therefore no solution
Solution 2Writing both equation as lines:
y = -4x + 6y = -4x - 1As we see both lines have a same slope. It means they are parallel and no intersection.
