a) The probability that all bolts are of acceptable diameter: From the lot of 90 bolts containing 8 bolts with unacceptable diameter, the number of acceptable bolts is 82. the probability of selecting no unacceptable bolt or one unacceptable bolt: P(No unacceptable bolt) + P(One unacceptable bolt)

= 1 - P(at least 2 unacceptable bolts)The probability of selecting no unacceptable bolt is:P(No unacceptable bolt) = (82/90) × (81/89) × (80/88) × ... × (69/77) × (68/76)The probability of selecting one unacceptable bolt is:P(One unacceptable bolt) = [(8/90) × (82/89) × (81/88) × ... × (69/83) × (68/82)] + [(82/90) × (8/89) × (81/88) × ... × (69/83) × (68/82)] + ... + [(82/90) × (81/89) × ... × (9/83) × (8/82)]P(One unacceptable bolt) ≈ 0.5068 (rounded to four decimal places)Therefore, P(at least 2 unacceptable bolts) unacceptable bolts.μ

= (0 × P(0)) + (1 × P(1)) + (2 × P(2)) + ... + (8 × P(8))

= (0 × P(0)) + (1 × P(1)) + (2 × P(2)) + (3 × P(3)) + (4 × P(4)) + (5 × P(5)) + (6 × P(6)) + (7 × P(7)) + (8 × P(8))= Σxp(x)For example, the probability of selecting exactly 3 unacceptable bolts is: P(3 unacceptable bolts)

= [(8/90) × (7/89) × (6/88)] × [(82/87) × (81/86) × ... × (76/77)]≈ 0.0156 (rounded to four decimal places)

= (0 × P(0)) + (1 × P(1)) + (2 × P(2)) + (3 × P(3)) + (4 × P(4)) + (5 × P(5)) + (6 × P(6)) + (7 × P(7)) + (8 × P(8))≈ 0.7759 (rounded to four decimal places)d) The variance for unacceptable bolts:. The variance for unacceptable bolts is:σ² = [(0 - 0.7759)² × P(0)] + [(1 - 0.7759)² × P(1)] + [(2 - 0.7759)² × P(2)] + ... + [(8 - 0.7759)² × P(8)]≈ 1.2919 (rounded to four decimal places)Therefore, the variance for unacceptable bolts is approximately 1.2919.

Answer:

1 19/360

Step-by-step explanation:

What we know:

The addends in this equation are 7/8 and 8/45.

First, find the LCM of 8 and 45. Since 8 and 45 don't have any common factors other than 1, just multiply the two numbers.

8 * 45 = 360

After that, find the equivalent fraction for both addends

7/8 * 45/45 = 315/360

8/45 * 8/8 = 64/360

Then, add the two new fractions together, and simplify if needed.

315/360 + 64/360 = 379/360 = 1 19/360

Answer:

LCM (k, n) = 10 and HCF(k, n) = 2

Step-by-step explanation:

The given parameters are;

The time after which Keshav takes  a break = k hours

The value of k = The first smallest prime natural number

Therefore, by mathematical definition, k = 2

The time after which Noel takes a break = n hours

The value of n = The fifth smallest composite natural number

The first five composite numbers are given as follows;

4, 6, 8, 9, and 10

Therefore, the fifth smallest composite natural number = 10 = n

The LCM (k, n) = LCM (2, 10) = Least common multiple of 2 and 10 is given as follows;

Dividing by 2, we get;

2/2 = 1,  10/2 = 5

Dividing the result by 5, we get;

5/5 = 1

Multiplying the devisors together gives;

5 × 2 = 10

Therefore, the LCM of 2 and 10 = 10

LCM(2, 10) = LCM (k, n) = 10

The HCF(k, n) = HCF of 2 and 10 = The highest common factor that divides both 2 and 10 is given as follows;

Dividing 2 and 10 by 2 gives;

2/2 = 1 and 10/2 = 5

Therefore, HCF(k, n) = The highest common factor of 2 and 10 = HCF(2, 10) = 2

The function for the model that gives the future value of the investment in dollars after t years is: f(t) = 2000.e⁰·°⁴²t

Give, a lump sum of $2000 is invested at 4.2% compounded continuously.

Hence we have:

P = $2000

years = t

we know that A = Pe^rt

Substitute the above values in the formula.

Amount = f(t)

f(t) = 2000.e⁰·°⁴²t

hence we get the function for the model that gives the future value of the investment is f(t) = 2000.e⁰·°⁴²t

Therefore we get the required function.

To find the union and intersection of the intervals I₁ = (-2, 2] and I₂ = [1, 5), let’s consider the overlapping values and the combined range.

The union of two intervals includes all the values that belong to either interval. Taking the union of I₁ and I₂, we have:

I₁ U I₂ = (-2, 2] U [1, 5)

To find the union, we combine the intervals while considering their overlapping points:

I₁ U I₂ = (-2, 2] U [1, 5)
= (-2, 2] U [1, 5)

So the union of the intervals I₁ and I₂ is (-2, 2] U [1, 5).

Now let’s find the intersection of the intervals I₁ and I₂, which includes the values that are common to both intervals:

I₁ ∩ I₂ = (-2, 2] ∩ [1, 5)

To find the intersection, we consider the overlapping range between the two intervals:

I₁ ∩ I₂ = [1, 2]

Therefore, the intersection of the intervals I₁ and I₂ is [1, 2].

After completing their trade, Store Owner A has 0 puzzles and 10 puppets, and Store Owner B has 30 puzzles and 0 puppets.

Here,

Let's assume the two toy store owners are Store Owner A and Store Owner B.

Before the trade, Store Owner A has 30 puzzles and 0 puppets, and Store Owner B has 0 puzzles and 10 puppets.

They agree to trade 30 puzzles for 10 puppets at a rate of 3 puzzles for each puppet.

So, for every 3 puzzles, Store Owner A will receive 1 puppet.

Store Owner A gives away 30 puzzles and receives 30 / 3 = 10 puppets.

After the trade, Store Owner A has 0 puzzles and 10 puppets.

Store Owner B gives away 10 puppets and receives 10 * 3 = 30 puzzles.

After the trade, Store Owner B has 30 puzzles and 0 puppets.

Therefore, the perimeter can be calculated by adding up all four sides: p = 2b + 2n.

To find the perimeter (p) of a parallelogram, you need to know the length of all four sides. However, in this case, you are given the ratio of the base (b) to one of the sides (a), which is n/a.
Since a parallelogram has two pairs of parallel sides, the opposite sides are equal in length. Therefore, if the base is b, then the opposite side is also b. Using the given ratio, you can find the length of the other side (n) by multiplying a by n/a, which is n.
So, the length of the other side is also n, and the perimeter can be calculated by adding up all four sides: p = 2b + 2n.
However, if given the ratio of the base to one of the sides, you can use this to find the length of the other side. For this problem, if the base is b, then the opposite side is also b, and the length of the other side is n (where n/a = b/a).

Therefore, the perimeter can be calculated by adding up all four sides: p = 2b + 2n.

Symbolically, they correspond to the relationships between the coefficients of the equations.

A system of 2 linear equations in 2 variables can have one of the following three possible solutions:

One unique solution: In this case, the two lines intersect at exactly one point, and this point is the solution to the system. Visually, the two lines are not parallel, but they are not the same either. Symbolically, the system is represented as:

a1x + b1y = c1

a2x + b2y = c2

where a1, b1, c1, a2, b2, and c2 are constants, and x and y are variables.

Infinitely many solutions: In this case, the two lines coincide and are on top of each other, meaning they have the same slope and the same y-intercept. Visually, the two lines are identical. Symbolically, the system is represented as:

a1x + b1y = c1

ka1x + kb1y = kc1

where a1, b1, and c1 are constants, x and y are variables, and k is any non-zero constant.

No solution: In this case, the two lines are parallel and never intersect. Visually, the two lines are distinct and never meet. Symbolically, the system is represented as:

a1x + b1y = c1

a2x + b2y = c2

where a1, b1, c1, a2, b2, and c2 are constants, and x and y are variables, and the slope of one line is not equal to the slope of the other.

The vector field f(x,y) = 33x^2y^2i + 22x^3yj is conservative, and its potential function is φ(x,y) = 11x^3y^2 + 11x^2y^2 + C.

To determine if a vector field is conservative, we need to check if it is the gradient of a scalar function (i.e., a potential function). We can do this by taking the partial derivatives of each component with respect to their respective variables and checking if they are equal:

∂f_x/∂y = 66xy^2
∂f_y/∂x = 66xy^2

Since these partial derivatives are equal, the vector field is conservative. We can then find a potential function by integrating each component with respect to their respective variable:

φ(x,y) = 11x^3y^2 + 11x^2y^2 + C

where C is the constant of integration.

Therefore, the vector field f(x,y) = 33x^2y^2i + 22x^3yj is conservative, and its potential function is φ(x,y) = 11x^3y^2 + 11x^2y^2 + C.
