A jar of peanut butter contains 442 g with a standard deviation of 10.2 g find the probability that a jar contains less than 436 g assume a normal distribution

Answer:

x = 1, y = -3

Step-by-step explanation:

So, we have two equations to start with: 3x-y=6 and y = x-4, we want to resolve the equations by addition.

We sum up the left sides of the equations together and the right sides together, and simplify, we have:

3x - y + y = 6 + x - 4

3x = 2 + x ==> 2x = 2 ==> x = 1

To find y, we place the value of x in any of the two equations:

y = x - 4 = 1 - 4 = -3

You verify that the solution is valid by entering the values of x and y in the other equation:

3x - y = 6 becomes

3 (1) - (-3) = 6

3 + 3 = 6

Answer:

x = 1 and y = -3

Step-by-step explanation:

The given linear equations are,

3x - y = 6 and y = x - 4

To solve the system of equations

Let 3x - y = 6   -----(1)

y = x - 4

x - y = 4  ----(2)

(2) * -3 ⇒ -3x  + 3y = -4   ----(3)

(2) + (3) ⇒

3x - y = 6  

-3x  + 3y = -12

0   +2y = -6

y = -6/2 = -3

x - y = 4  

x = 4 + y = 4 + -3 = 1

x = 1 and y = -3

Answer:

$140,000(1 - .05)^t

Step-by-step explanation:

you have your total amount $140,000

it is decreased by 5% go behind the number and move two decimal points and you get .05

since is decreasing it would be 1 subtracted by ,05

$140,000(1 - .05)^t

"t" is the years it would be depreciated by

I do not see years but by knowledge i would say it is decreasing

Answer:

Since, the exponential decay function,

[tex]A=P(1-r)^t[/tex]

Where,

P = initial value,

r = rate per period,

t = number of periods,

Here, P = $ 200,000, r = 5% = 0.05,

Thus, the value of the condominium would be,

[tex]A=200000(1-0.05)^t=200000(0.95)^t[/tex]

Which is the required equation.

If A < 140,000

[tex]200000(0.95)^t < 140000[/tex]

By the graphing calculator.

[tex]t< 6.95364[/tex]

Hence, about after 7 years the condominium will be worth less than $140,000.

Answer: 43.3 inches.

Step-by-step explanation:

According to the Pythagorean Theorem:

[tex]a^2=b^2+c^2[/tex]

Where "a" is the hypotenuse, and "b" and "c" are the legs of the right triangle.

Let be "c" the width of the television.

We can indentify in the figure that:

[tex]a=50in\\b=25in[/tex]

Then, we can substitute values and solve for "c":

[tex](50in)^2=(25in)^2+c^2\\\\c=\sqrt{(50in)^2-(25in)^2}\\\\c=43.30in[/tex]

Rounded to the nearest tenth:

[tex]c=43.3in[/tex]

Final answer:

The width of a flat screen television with a 50 inch diagonal and a 25 inch height is found to be approximately 43.3 inches when calculated using the Pythagorean Theorem.

Explanation:

To find the width of a flat screen television with a 50 inch diagonal and a height of 25 inches, we will apply the Pythagorean Theorem. The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Here, the diagonal is the hypotenuse (c), the height is one leg (a), and the width is the other leg (b).

The Pythagorean Theorem is written as:

a2 + b2 = c2

Using the given measurements:

252 + b2 = 502

Solving for b, we have:

b2 = 502 - 252

b2 = 2500 - 625

b2 = 1875

b = √1875

b ≈ 43.3 inches (rounded to the nearest tenth)

Therefore, the width of the television is approximately 43.3 inches.

Answer: 15 cookies and 5 brownies will be required.

Step-by-step explanation:

Given in the question is Eder needs 6 cookies and 2 brownies for 4 plates.

We have to calculate the cookies and brownies required for 10 plates.

Let's first calculate the cookies by unitary method.

⇒ 4 plates required cookies = 6 cookies

⇒  1 plate will require cookies = 6/4

⇒ 10 plates will require cookies = 6×10/4 = 15

Similarly we will calculate the brownies.

⇒ 4 plates required number of brownies = 2

⇒1 plate will require = 2/4 brownies

⇒10 plates will require = 2×10/4 = 5 brownies

⇒Therefore 15 cookies and 5 brownies will be required for 10 plates.

* Hopefully this helps:)

For 4 plates, an editor needs 1.5 cookies and 0.5 brownies. Thus, for ten plates, they will require 15 cookies and 5 brownies.

Let's start by determining the amount of cookies and brownies the editor needs for 4 plates. As per the given information, the editor needs 6 cookies and 2 brownies for every 4 plates. Therefore, for each plate, the editor will need to have 1.5 cookies (6/4 = 1.5) and 0.5 brownies (2/4 = 0.5).

Now, let's compute how much this would translate to if we have ten plates. Using the ratio we determined earlier, for ten plates the editor would need:

This is the simplest way to figure out how many cookies and brownies are needed for a given number of plates, provided you know how much is needed per plate.

Answer:

f(g(-8)) = -26

Step-by-step explanation:

Given:

f(x)=2x and g(x)=2x+3

Required:

f(g(-8))=?

Solution:

First we will find g(-8)

g(x) = 2x+3

g(-8)= 2(-8)+3

      = -16 + 3

      = -13.

so, g(-8) = -13

Now, for calculation f(g(-8)) we can put the value of g(-8) i.e, -13

so, f(x) = 2x

    f(-13)  = 2(-13)

             = -26

so, f(-13) = -26

and f(g(-8)) = -26

The equation to calculate the remaining money on Joan's gym gift card after d gym visits is m = 100 - 12d.

To determine the amount of money (m), in dollars, remaining on Joan's gym gift card after she visits the gym d times, you can use a simple linear equation.

Since she starts with $100 on the card, and each gym visit costs $12, you subtract $12 for each visit from the initial amount. The equation that represents this situation is m = 100 - 12d.

Here, d is the number of times she visits the gym, and m is the money remaining on the card.

7 is the median

The median of the data set [1, 2, 6, 7, 8, 9.4, 9.9, 9.9] is not 9.4, but instead is 7.5, which is calculated by getting the average of the two middle values, in this case, 7 and 8.

The given set of data is: [9.4, 9.9, 9.9, 8, 7, 6, 1, 2]. The first step is to put the data in numerical order, so we have [1, 2, 6, 7, 8, 9.4, 9.9, 9.9]. The median is the middle value in an ordered data set. Since this set has an even number of data values (8), the median is calculated as the average of the two middle values. Here, the middle values are 7 and 8. Therefore, to find the median, we add these two values together and divide by 2. Hence, 7 + 8 = 15, and 15 divided by 2 equals 7.5. Therefore, the median of this data set is 7.5, not 9.4.
