If a random variable has binomial distribution with n = 150 and p = 0.6. Using normal approximation the probability; P(X≥ 95) =---

Answers

Answer 1

The required probability is 0.2023.

Given random variable X with binomial distribution with n=150 and p=0.6.

The binomial distribution with parameters n and p has probability mass function:

$$f(x)= \begin{cases} {n\choose x} p^x (1-p)^{n-x} & \text{for } x=0,1,2,\ldots,n, \\ 0 & \text{otherwise}. \end{cases}$$

Now the mean, μ = np = 150 × 0.6 = 90 and standard deviation, σ = √(npq) = √(150 × 0.6 × 0.4) = 6

Using the normal approximation,

we have:

$$\begin{aligned}P(X ≥ 95) &\approx P\left(Z \geq \frac{95 - \mu}{\sigma}\right)\\ &\approx P(Z \geq \frac{95 - 90}{6})\\ &\approx P(Z \geq 0.8333) \end{aligned}$$

Using the standard normal table, the area to the right of 0.83 is 0.2023.

Therefore, P(X ≥ 95) = 0.2023.

Answer 2

According to the given information, the required probability is 0.2019.

The random variable has a binomial distribution with n = 150 and p = 0.6.

We can use the normal approximation to the binomial distribution to find the probability P(X ≥ 95).

Normal Approximation:

The conditions for the normal approximation to the binomial distribution are:

np ≥ 10 and n(1 - p) ≥ 10

The expected value of the binomial distribution is given by the formula E(X) = np

and the variance is given by the formula [tex]Var(X) = np(1 - p)[/tex].

Let X be the number of successes among n = 150 trials each with probability p = 0.6 of success.

The random variable X has a binomial distribution with parameters n and p, i.e., X ~ Bin(150, 0.6).

The expected value and variance of X are:

[tex]E(X) = np = 150(0.6) = 90[/tex],

[tex]Var(X) = np(1 - p) = 150(0.6)(0.4) = 36[/tex].

The probability that X takes a value greater than or equal to 95 is:

[tex]P(X ≥ 95) = P(Z > (95 - 90) / (6))[/tex]

where Z ~ N(0,1) is the standard normal distribution with mean 0 and variance 1.

[tex]P(X ≥ 95) = P(Z > 0.8333)[/tex]

We can use a standard normal distribution table or a calculator to find this probability.

Using a standard normal distribution table, we find:

[tex]P(Z > 0.8333) = 0.2019[/tex]

Thus, [tex]P(X ≥ 95) = 0.2019[/tex] (rounded to four decimal places).

Therefore, the required probability is 0.2019.

This equation has some nested grouping symbols on the left-hand side. As usual, I'll simplify from the inside out. I'll start by inserting the "understood" 1 in front of that innermost set of parentheses:

3 + 2[4x – (4 + 3x)] = –1

3 + 2[4x – 1(4 + 3x)] = –1

3 + 2[4x – 1(4) – 1(3x)] = –1

3 + 2[4x – 4 – 3x] = –1

3 + 2[1x – 4] = –1

3 + 2[1x] + 2[–4] = –1

3 + 2x – 8 = –1

2x + 3 – 8 = –1

2x – 5 = –1

2x – 5 + 5 = –1 + 5

2x = 4

x = 2
It is not required that you write out this many steps; once you get comfortable with the process, you'll probably do a lot of this in your head. But until you reach that comfort zone, you should write things out at least this clearly and completely.

Always remember, by the way, that you can check your answers in "solving" problems by plugging the numerical answer back in to the original equation. In this case, the variable is only in terms on the left-hand side (LHS) of the equation; my "check" (that is, my evaluation at the solution value) looks like this:

LHS: 3 + 2[4x – (4 + 3x)]:

3 + 2[4(2) – (4 + 3(2))]

3 + 2[8 – (4 + 6)]

3 + 2[8 – (10)]

3 + 2[–2]

3 – 4

–1
Since this is what I was supposed to get for the right-hand side (that is, I've shown that the LHS is equal to the RHS), my solution value was correct.

A secret agent wants to break a 6-digit code. He knows that the sum of the digits in even positions is equal to the sum of the digits in odd positions. Which of the following numbers could be the code?

A)12*9*8. B)181*2

Answers

The code could be the number "181*2" since the sum of the digits in even positions (8+2) is equal to the sum of the digits in odd positions (1+1).(option A)

To determine if a number could be the code, we need to check if the sum of the digits in even positions is equal to the sum of the digits in odd positions.

Let's analyze the options:

A) 12*9*8: The sum of the digits in even positions is 1+9 = 10, while the sum of the digits in odd positions is 2+8 = 10. Therefore, this number could be the code.

B) 181*2: The sum of the digits in even positions is 8+2 = 10, and the sum of the digits in odd positions is 1+1 = 2. These sums are not equal, so this number cannot be the code.

Based on the given information, only option A (1298) satisfies the condition where the sums of the digits in even and odd positions are equal.

Let T: R3 → R3 be the linear transformation that projects u onto v = (a) Find the rank and nullity of T (b) Find a basis for the kernel of T.

Answers

The linear transformation T: R³ → R³ that projects u onto v has Rank(T) = 1 and the basis for the kernel of T is {a}.

To find the rank and nullity of the linear transformation T: R³→ R³, we need to determine the dimensions of the image space (range) and the kernel (null space) of T.

(a) Rank of T:

The rank of T is equal to the dimension of the image space. Since T projects u onto v, the image of T is the span of the vector v. Therefore, the rank of T is 1.

Rank(T) = 1

(b) Basis for the kernel of T:

The kernel of T consists of all vectors u in R³ that are mapped to the zero vector in R³. In other words, it consists of all vectors u perpendicular to the vector v.

To find a basis for the kernel, we need to solve the equation T(u) = 0. Since T projects u onto v, we can express this as u - proj_v(u) = 0.

For any vector u in R³, the projection of u onto v can be computed as:

proj_v(u) = (u · v) / (||v||²) * v

where u · v represents the dot product of u and v, and ||v|| is the norm (length) of v.

In this case, v = (a), so we can rewrite the projection formula as:

proj_v(u) = (u · (a)) / (||a||²) * (a)

Since T(u) = u - proj_v(u) = 0, we have:

u - (u · (a)) / (||a||²) * (a) = 0

This equation can be rearranged as:

u = (u · (a)) / (||a||²) * (a)

Now we can find a basis for the kernel by setting u to be a free variable and expressing it in terms of (a).

Let's denote the scalar (u · (a)) / (||a||²) as k:

u = k * a

Therefore, any vector in the kernel of T can be written as k * a, where k is a scalar.

A basis for the kernel of T is {a}.

So, the basis for the kernel of T is {a}.

Taking the given data into consideration we reach the conclusion that the IQ score ranging the bottom 15% from the top 85% is approximately 79.2, under the standard deviation 20.

Let us assume that adults have IQ scores that are normally expressed  with a mean of 100 and a standard deviation of 20, we need to calculate the IQ score ranging the bottom 15% from the top 85%, which is denoted as [tex]P_{15}[/tex]
To find the answer for this problem, we need to evaluate the z-score that corresponds to the 15th percentile. We can utilise a standard normal distribution table to  evaluate this value.
Implementing a standard normal distribution table, we could evaluate that the z-score corresponding to the 15th percentile is approximately -1.04.
[tex]z = (P_{15} - mean) /standard deviation[/tex]
[tex]-1.04 =( P_{15} - 100) /20[/tex]
[tex]- 20.8 = P_{15} - 100[/tex]

If the point (-4,-8) is on the graph of the function L(x) and the slope of the line is 15, what is the equation for the function L(x).

Answers

The equation of the function L(x) is given by y = 15x + 52.

To find the equation of the function L(x), given that the point (-4, -8) is on the graph of the function L(x) and the slope of the line is 15, we use the point-slope form of the equation of a line.

Let's assume that the equation of the function L(x) is of the form y = L(x).

The slope of the line, m = 15

The point (-4, -8) is on the line, which means that it satisfies the equation of the line: y - y1 = m(x - x1),

where (x1, y1) = (-4, -8)

Substituting m, x1 and y1 in the equation of the line, we get:

y - (-8) = 15(x - (-4))y + 8

= 15(x + 4)y + 8

= 15x + 60y

= 15x + 52

The equation of the function L(x) is y = 15x + 52.

A graphical interpretation of the 2-point backward difference formula for approximating f'(x) is the slope of the line joining the points of abscissas xo - h and X, with h > 0 is False

The 2-point backward difference formula for approximating f'(x) is given by:

f'(x) ≈ (f(x) - f(x - h)) / h

In this formula, the slope is calculated using the values of f(x) and f(x - h) at two points: x and x - h. The graphical interpretation of this formula involves finding the slope of the line passing through these two points.

However, the given statement states that the line is joining the points of abscissas xo - h and X, with h > 0. This implies that the line is connecting a fixed point xo - h to a variable point X. This interpretation does not align with the 2-point backward difference formula.

The velocity vector of a particle moving in the XY plane has components given by dx/dt= sin(t^2) and dy/dt= e^(cost). At time t=4 the position of the particle is (2,1). What is the y-coordinate of the position vector at time t=3.

Answers

The y-coordinate of the position vector at time t=3 is approximately 1.446.

For the y-coordinate of the position vector at time t=3, we first need to integrate the given velocity components with respect to time to obtain the position components:

x(t) = ∫(dx/dt) dt = ∫sin(t²) dt

= (1/2)∫sin(u)/√(u) du

(where u = t²)

y(t) = ∫(dy/dt) dt

= ∫[tex]e^{cos t}[/tex] dt = [tex]e^{cos t}[/tex] + C

We can then use the given initial condition at time t=4 to determine the constant value C for the y-component:

x(4) = 2, y(4) = 1

Plugging in t=4 to the position equations, we get:

x(4) = (1/2)∫sin(u)/√(u) du = 2

y(4) = [tex]e^{cos 4}[/tex] + C = 1

Solving for C, we get:

C = 1 -  [tex]e^{cos 4}[/tex]

Now we can plug in t=3 to find the y-coordinate of the position vector:

y(3) =  [tex]e^{cos 3}[/tex] + C

y(3) =  [tex]e^{cos 3}[/tex] + 1 -  [tex]e^{cos 4}[/tex]

y(3) ≈ 1.446 (rounded to three decimal places)

Therefore, the y-coordinate of the position vector at time t=3 is , 1.446.
