A manufacturer produces a large number of toasters. From past experience, the manufacturer knows that approximately 2% are defective. In a quality control procedure, we randomly select 20 toasters for testing. We want to determine the probability that no more than one of these toasters is defective.

Answers

The probability that a randomly selection of 20 toasters for testing, no more than one is defective is: 0.9401

To solve this exercise the formula and the procedure that we have to use for binomial distribution is:

P(x) = n! /[x! *(n-x)!] * pˣ * (1 - p)ⁿ⁻ˣP = P(0) + P(1)

Where:

n = number being sampled or trialsp = probability of getting a success in one trial1 - p = probability of getting a failure in one trialx = number of successes desired

Information about the problem:

n = 20 toastersp = 2% = 0.021 - p = 1 - 0.02 = 0.98x = no more than one

Applying the binomial distribution formula, we get:

P(x) = n! /[x! *(n-x)!] * pˣ * (1 - p)ⁿ⁻ˣ

P(x) = 20! /[x! *(20-x)!] * 0.02ˣ * (1 - 0.02)²⁰⁻ˣ

Using the P formula to calculate the probability that no more than one of these toasters is defective, we have:

P = P(0) + P(1)

P(0) = 20! /[0! *(20-0)!] * 0.02⁰ * (1 - 0.02)²⁰⁻⁰

P(0) = 20! /(0!*20!) * 0.02⁰ * (0.98)²⁰

P(0) = 1/0! * 1 * 0.6676

P(0) = 1/1 * 1 * 0.6676

P(0) = 0.6676

P(1) = 20! /[1! *(20-1)!] * 0.02¹ * (1 - 0.02)²⁰⁻¹

P(1) = 20! /(1!*19!) * 0.02¹ * (0.98)¹⁹

P(1) = (20*19!) / (1!*19!) * 0.02¹ * (0.98)¹⁹

P(1) = 20/1! * 0.02 * 0.6812

P(1) = 20 * 0.02 * 0.6812

P(1) = 0.2725

P = P(0) + P(1)

P =  0.6676 + 0.2725

P =  0.9401

The permutation system is used to locate the special range of preparations that may be shaped through taking r matters from the n to be had matters. Permutations are beneficial to shape distinctive words, quantity preparations, seating preparations, and for al. of the conditions related to special preparations. As consistent with the permutation formula, the permutation of 'r' items taken from 'n' items is identical to the factorial of n divided through the factorial of distinction of n and r.

The formula for permutations is

nPr= n!/(n-r)!

From the given question let us consider,

n= 24    r=3

Now let us solve using formula

24P3= 24!/(24-3)!

in the right angled triangle abc below ab =bc. the size of C is.. ​

Answers

All angles have to add up too 180
So we know B is 90 since it’s a right triangle
and A and C have to be the same
So 180-90=90
Then divide by 2
90/2=45

Answer:

45°

Step-by-step explanation:

AB and BC are congruent which mean ∠BAC and ∠BCA are congruent.

We already know ∠ABC is 90°.

We cans set up the equation with what is given.

180 = 90 + 2c

Subtract 90 from both sides.

90 = 2c

Divide both sides by 2

45 = C

So angle C is 45°

Simplify each trigonometric expression. csc θ / sinθ+cos θcotθ

Answers

The simplified form of trigonometric expression, cosec θ / sin θ + cos θ cot θ is 1.

Given,

The trigonometric expression = cosec θ / sin θ + cos θ cot θ

We have  to simplify this expression.

For that we can use trigonometric identities.

cosec θ = 1 / sin θ

cot θ = cos θ / sin θ

We can substitute the above given identities in the expression.

Then we get,

cosec θ / sin θ + cos θ cot θ = (1 / sin θ) / (sin θ + cos θ x (cos θ/sin θ))

= (1 / sin θ) / ((sin²θ + cos²θ) / sin θ)

Cancel sin θ from both numerator and denominator.

= 1 / sin² θ + cos² θ

We know that sin² θ + cos² θ = 1

So, we get,

1 / sin² θ + cos² θ = 1 / 1 = 1

Therefore, the simplified form of  cosec θ / sin θ + cos θ cot θ is 1.

Write the lower and upper bounds for the following to the given degrees of accuracy. a 64mins (nearest 1 min) c 30m/s (nearest 5m/s) b 20g (nearest 10g) d 7500 (nearest 100mm)

Answers

The lower and upper bounds for the following to the given degrees of accuracy are: a- 64 mins (63.5 ≤ 64 < 64.5) c- 30m/s (27.5 ≤ 30 < 32.5) b- 20g (15 ≤ 20 < 25) d-7500mm (7450 ≤ 7500 < 7550)

The upper and lower bounds can be found by dividing the degrees of accuracy by 2 and then subtracting and adding with the value to give the lower and upper bounds respectively.

For a- 64 mins (nearest 1 min)

As the degree of accuracy is to the nearest 1 min;

1 min ÷ 2 = 0.5 min

Upper bound = 64 + 0.5 = 64.5 min

Lower bound = 64 - 0.5 = 63.5 min

For c- 30m/s (nearest 5m/s)

5m/s ÷ 2 = 2.5 m/s

Upper bound = 30 + 2.5 = 32.5 m/s

Lower bound = 30 - 2.5 = 27.5 m/s

For b- 20g (nearest 10g)

10g ÷ 2 = 5

Upper bound = 20 + 5 = 25g

Lower bound = 20 - 5 = 20g

For d- 7500(nearest 100mm)

100mm ÷ 2 = 50mm

Upper bound = 7500 + 50 = 7550mm

Lower bound = 7500 - 50 = 7450mm

For each pair of functions, find f(g(x)) and g(f(x)) .

Answers

A composite function exists as a function that depends on another function. A composite function exists formed when one function exists substituted into another function.

The value of g(3x) = 9x.

What is meant by composition function?

In mathematics, function composition exists as an operation ∘ that takes two functions f and g, and has a function h = g ∘ f such that h(x) = g. In this operation, the function g exists used to the result of applying the function f to x.

Function composition is a mathematical procedure where two functions, f, and g, are taken and a function, h = g ∘ f, is produced such that h(x) = g(f(x)). The function g exists used in this operation on the outcome of applying the function f to x.

Let the two functions be f(x) = 3x and g(x) = x²

f(g(x)) = f(x²)

f(x²)  =  3x²

simplifying the above equation, we get

g(f(x)) = g(3x)

g(3x) = (3x)²

g(3x) = 9x

Therefore, the value of g(3x) = 9x.

What is a linear equation in mathematics?

A linear equation is an algebraic equation of the form y=mx+b, including only a constant and a first-order (linear) component, where m is the slope and b is the y-intercept. The preceding is sometimes referred to as a "linear equation with two variables," where y and x are the variables.

According to the given data:

y = ax2 + bx + c

When:

x = 0 , y = 6

y = a(0)2 + b(0) + c = 6

c = 6

When x = 2, y = 22

a(2)2 + b(2) + 6 = 22

4a + 2b = 16

On dividing the entire equation by 2,

2a + b = 8 → (1)

When x = 4, y = 22

a(4)2 + b(4) + 6 = 22

16a + 4b + 6 = 22

16a + 4b = 16

On dividing the entire equation by 4,

4a + b = 4 → (2)

Subtracting (1) from (2)

2a = -4

a = -2

b = 4 - 4(-2) = 4 + 8

b = 12

y = -2x2 + 12x + 6

y = -2x + 12x + 6

Solve the equation.

On solving using quadratic formula,

x = (-12 ± √(144 - 4*-2*6) ) / -4

x = (-12 ± 13.8564) / -4

x ≈ -0.46 and x ≈ 6.46

The ball is above seconds

-2x2 + 12x + 6 = 10

2x2 - 12x + 4 = 0

On solving the above equation using quadratic formula,

x ≈ 0.354 and x ≈ 5.646

So, the ball is above 10 feet for about,

5.646 - 0.354 = 5.3 seconds

5.3 seconds

According to the solving the ball will be in the air for:

Roman saves $500 each year in an account earning interest at an annual rate of 4% compounded annually. How much interest will the account earn at the end of the first 2 years?

Answers

First what needs to be done is find out what 4% of $500 is, and add that to $500 to get how much money you would have after the first year.
4% of 500 would be 20, so you'd have $520 after the first year.
Now, find 4% of $520, for the second year. 4% of $520 would be 20.8, so add that and get $540.8.
Now for the last year, find 4% of $540.8.
That would be 21.632.
Round 21.632 to the nearest hundredth:
21.63
add that to $540.8: $562.43.
