As part of a manufacturing process for widgets, an quality controller at ACME Corporation randomly samples 856 widgets during a day of production to test the current rate of defective widgets. The controller finds 34 defective widgets.The historical rate of defective widgets produced by ACME Corporation was 7%. Approximately, how many standard deviations is the point estimate from 7%?

Answers

Answer 1

The historical rate of defective widgets produced by ACME Corporation was 7%. Approximately, 91.2 is the standard deviations is the point estimate from 7%.

In statistics, standard deviation is a measure of the amount of variation or distribution of a set of values. A low standard deviation indicates that the values ​​tend to be close to the ensemble mean (also called the expected value), while a high standard deviation indicates that the values ​​are spread over a wider range.

The standard deviation can be abbreviated SD, and is most commonly used in mathematical texts and equations with the lowercase Greek letter σ (sigma) for the population standard deviation, or the Latin letter s for the standard deviation of the sample.

The standard deviation of a random variable, sample, population, data set, or probability distribution is the square root of its variance. It is algebraically simpler than the mean absolute deviation, although less robust in practice. A useful property of the standard deviation is that, unlike the variance, it is expressed in the same units as the data.

According to the Question:

Given that:

Defective widgets produced by ACME corporation was 7%

Total sample was 856 widgets.

Therefore, the Standard Deviation estimates from 7% is:

856 of 7% = 91.2

Find the length of the missing side. If necessary, round to the nearest tenth. 16 14 b

Answers

Pythagorean Theorem can be used to find the missing side that is equal to 21.3.

What is the distance formula?

Distance formula states that the distance between two points is equal to the square root of the sum of the squares of the differences of the coordinates.

The missing side can be found by using the Pythagorean Theorem, which states that the square of the length of the hypotenuse (longest side of a right triangle) is equal to the sum of the squares of the lengths of the other two sides.

Therefore, the missing side is equal to the square root of the sum of the squares of the sides we already have:

b² = (16)² + (14)²

= 256 + 196

= 452

b = √452

= 21.3

We can also use the distance formula here.

The distance between (16, 14) and (0, 0) =

√(16² + 14²)

= √(256 + 196)

= √452

= 21.3.

This confirms that the missing side is equal to 21.3.

Answers

So the acute angle of the rhombus is 90 degrees, and the obtuse angle is twice as large, or 180 degrees.

The Pythagorean theorem is a fundamental concept in geometry that describes the relationship between the sides of a right triangle. It states that in a right 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.

Let's start by finding the length of one half of the longer diagonal. We can use the shorter diagonal (which we know is 10 cm) and the side length (which we know is 13 cm) to form a right triangle. The hypotenuse of this triangle is half of the longer diagonal, so we can solve for it using the Pythagorean theorem:

[tex]a^2+b^2 = c^2 \\(13/2)^2 + 10^2 = c^2\\169/4+100 =c^2 \\ 269/4= c^2 \\c = \sqrt{(269)}/2\\[/tex]

Therefore, the length of one half of the longer diagonal is sqrt(269)/2 cm. To find the full length of the longer diagonal, we just need to double this value:

longer diagonal = [tex]2 \times \sqrt{(269)}/2 = \sqrt{(269)}cm[/tex]

Now, we can use the fact that the sum of the angles in a rhombus is 360 degrees to solve for x:

2x + 2x = 360

4x = 360

x = 90

What is the probability of drawing a lettered card from a deck of shuffled 52 cards

Answers

The probability of drawing a lettered card from a deck of shuffled 52 cards is 50%.

Calcuating the probability of drawing a lettered card

There are 52 cards in a deck, and 26 of them are lettered cards (A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2) while the other 26 cards are suited cards (clubs, spades, hearts, diamonds).

If the deck is well shuffled, each card is equally likely to be drawn.

Therefore, the probability of drawing a lettered card from a deck of shuffled 52 cards is simply the number of lettered cards divided by the total number of cards:

P(Drawing a lettered card) = Number of lettered cards / Total number of cards

= 26 / 52

= 1/2

Answers

According to the given figure, the area of the shaded region in the shape is 49.5mm2.

Explain area?

The total area of every one of the shapes which cover an object's surface is known as its surface area. The length and width of this type of rectangle are multiplied to determine its area.

To solve the following question we first need to separate the single shape into two according to the shapes given

Therefore we have two shapes with us, i.e., rectangle and triangle.

First of all, we need to calculate the area of both the shares separately:

Firstly, area of the rectangle, formula is:

Area = length x width

By entering the length and width values,

Area of rectangle= 7 x6

Area of rectangle= 42 mm2

Now, we need to calculate the area of the second shape, that is, triangle,

Triangle area is equal to height x base / 2.

Now, by putting values in the formula:

Area of triangle=3 x 5 / 2

Area of triangle= 15/2

Area of triangle= 7.5 mm2

Therefore, the area of the shaded region:

Area = (rectangular area + triangular area)

Area = 42 + 7.5

Area = 49.5 mm2

Therefore, the area of the shaded region of the shape given is 49.5 mm2.

Submit

Answers

Hello and greetings ririleyyyii

The discriminant of 6y² - 9y + 1 = 0 equals 57.

Step-by-step explanation:

6y² - 9y + 1 = 0

We identify the coefficients a, b and c of the quadratic equation.

The coefficients of a quadratic equation are the numbers that multiply the variables together with the independent term.

ax² + bx + c = 0

The coefficient a is usually called the leading or main coefficient and multiplies the term x.The coefficient b is usually called the linear coefficient and multiplies the term x.The coefficient c is the independent or constant coefficient.

So the coefficients are: a = 6, b = -9, c = 1.

We evaluate the discriminant by substituting a, b and c inside the expression b² - 4ac.

The exercise remains: (-9)² - 4 × 6 × 1

                                      (-9)² - 4 × 6

                                      81 - 4 × 6 = 24, so 81 - 24 = 57

Number of girls in the class: 44

Number of girls who walk to school: 17

Number of boys who cycle to school: 14

Number of boys who take the bus to school: 12

Find the inverse function in slope intercept form f(x)=-x+3

What's inverse function?

An inverse function is a function that reverses the operation of another function. More specifically, if f is a function that maps inputs from a set A to labors in a set B, also an inverse function g is a function that maps labors from B back to inputs in A, similar that for any input x in A, applying f and also g (or g and also f) results in the same value. In other words, if f(a) = b, also g(b) = a

by the question.

To find the inverse function of f(x) = -x + 3 in slope-intercept form, we need to solve for x in terms of y.

Start by replacing f(x) with y:

[tex]y=-x+3[/tex]

Now, isolate x on one side of the equation. To do this, we can add x to both sides:

[tex]y+x=3[/tex]

Finally, solve for x by subtracting y from both sides:

let f-1(x) = y

then, f(y) = x

so, (2y)/(9+2y) = x    

 ***remember the thing inside the () in  f(x) can change! y can go in x's place, any number or any other variable can go in x's place! BUT, nothing else can be changed in the function***                

   now just solve for y!

multiply both sides by (9+2y): 2y = 9x + 2xy

bring the y's together (subtract both sides): 2y-2xy =9x

hey! we can factor the left side (where the y's are): 2y(1-x) = 9x

get all the x's together  (divide both sides) : 2y = (9x)/(1-x)

get y alone (divide both sides by 2): (9x)/(1-x) * (1/2)

The quadratic function in vertex form is  f(x) = -(x + 5)^2 - 23

What is the quadratic function?

To find the quadratic function in standard form, we first need to determine the factors of the quadratic equation that corresponds to the given x-intercepts. Since the x-intercepts are at x = -12 and x = 2, we can write the quadratic equation in factored form as:

f(x) = a(x + 12)(x - 2)

where a is a constant that we need to determine.

To find the value of a, we can use the given minimum y-value of -49. Since the vertex of a quadratic function occurs at the axis of symmetry, which is the midpoint of the x-intercepts, we can find the x-coordinate of the vertex by taking the average of the x-intercepts:

x-coordinate of vertex = (-12 + 2)/2 = -5

Substituting this value of x into the factored form of the quadratic function, we get:

f(-5) = a(-5 + 12)(-5 - 2) = 49a

Since the minimum y-value is -49, we have:

f(-5) = 49a = -49

Solving for a, we get:

a = -1

Substituting this value of a into the factored form of the quadratic equation, we get:

f(x) = -(x + 12)(x - 2)

Expanding this equation, we get the quadratic function in standard form:

f(x) = -x^2 - 10x - 24

To find the quadratic function in vertex form, we can complete the square on the standard form of the equation:

f(x) = -x^2 - 10x - 24

f(x) = -(x^2 + 10x) - 24

f(x) = -(x^2 + 10x + 25) + 1 - 24

f(x) = -(x + 5)^2 - 23

In a jar , there are 4 blue marbles, 3 green marbles, 7 red marbles and 2 white marbles. Find p(g)

Answers

The probability of selecting a green marble from a jar containing 4 blue marbles, 3 green marbles, 7 red marbles, and 2 white marbles is 0.1875 or 18.75%.

To find p(g), we need to first determine the total number of marbles in the jar, and then determine the number of green marbles in the jar.

Total number of marbles = 4 blue marbles + 3 green marbles + 7 red marbles + 2 white marbles = 16 marbles.

Number of green marbles = 3.

So p(g) = number of green marbles / total number of marbles = 3 / 16.

Therefore, p(g) = 0.1875 or 18.75%.

Mrs.Carter took her family and friends to the movies. There were a total of 16 people. Children tickets cost $6 and adult tickets cost $9. She spent a total of $129. How many children went to the movies

Answers

Answer:

11 adults

Step-by-step explanation:

First, set up a system of equations:

Let x = number of children and y = number of adults

There is a total of 16 people, so x+y = 16. This is your first equation.

Each child ticket costs $6, so 6x = cost of children's tickets based on the number of children present (x)

Each adult ticket costs $9, so 9y = cost of adult's tickets based on the number of adults present (y)

The total cost of tickets is $129, so 6x+9y = 129. This is your second equation.

Your system of equations is now this:

x +   y = 16

6x + 9y = 129

You can solve this system using the method of elimination, where we will eliminate the variable x (number of children), since we are focused on y (number of adults).

Multiply the top equation by -6. This will give the following equation:

-6x - 6y = -96

You can now solve the system of equations by placing the new equation under the second equation like this:

6x + 9y = 129

-6x - 6y = -96

Now, add the two equations together.

6x + (-6x) = 0

9y + (-6y) = 3y

129 + (-96) = 33

After doing this, you get the following equation:

3y = 33

As you can see, the variable x has been eliminated, and you are left with y.

Solve the equation for y:

3y = 33

y = 33/3 = 11

y = 11 adults

Answers

Using a calculator, the line of best fit for the ice cream sales in the function of the daily temperature is given by:

y = 6.5x - 279.1.

To find the equation, we need to insert the points (x,y) in the calculator. The same is true for any regression equation such as quadratic or exponential. However, as the problem states, a line of best fit is calculated in this problem.

From the table presented in the problem, the points are given as follows:

(58.2, 112), (64.2, 135), (64.3, 138), (66.8, 146), (68.4, 166), (71.6, 180), (72.7, 188), (76.2, 199), (77.8, 220), (82.8, 280).

Inserting these points into the calculator, the line of best fit for the ice cream sales in the function of the daily temperature is given by:

y = 6.5x - 279.1.

Here

x is the daily temperature, in F.

y is the sales, in dollars.
