Step-by-step explanation:

Assuming the oatmeal raisin and sugar cookies have an equal probability, it is less likely that a chocolate chip cookie will be picked since the other two cookies have a 37.5% chance of being picked. Despite this, it is still both likely and unlikely since it is only a small difference.

To conclude, it depends on what your teacher or textbook think. If they think a 12.5% difference between the other two cookies means that chocolate chip is unlikely, then it's unlikely. In my opinion, it is not equally but near equally likely and unlikely.

Domain : { x ∈ R : x ≥ 7 }

Range: { f ∈ R : f ≥ 9 }

Given function is:

So, Range is all real f's values when f ≥ 9.

2x＝ 3 -5√x using log form, x = log(2x + 5√x) = log(3)

To convert the equation 2x = 3 - 5√x into logarithmic form, we need to isolate the radical expression on one side of the equation. We can do this by adding 5√x to both sides:

2x + 5√x = 3

Next, we'll take the square root of both sides to eliminate the radical:

√(2x + 5√x)^2 = √(3^2)

Expanding the left side and simplifying:

2x + 5√x = 3

Finally, we'll take the logarithm of both sides to get x in logarithmic form:

log(2x + 5√x) = log(3)

To solve for x, we'll need to use logarithmic properties and/or exponential functions to isolate x on one side of the equation. log(2x + 5√x) = log(3)

The equation in x and y whose graph is the path of the particle is y = (x - 4)2 + 5. The velocity vector at t= 4 is v(4) = i + 8j.

A vector in mathematics is a quantity that not only expresses magnitude but also motion or position of an object in relation to another point or object. Euclidean vector, geometric vector, and spatial vector are other names for it.

In mathematics, a vector's magnitude is defined as the length of a segment of a directed line, and the vector's direction is indicated by the angle at which the vector is inclined.

Given r(t) as r(t) = x(t)i + y(t)j

Thus, this means that:

x = t+ 4         y = t2 + 5      

We see that we can solve t as:            

t = x - 4, thus:

y = (x - 4)2 + 5

v(t) is given by r'(t).

r'(t) = v(t) = i + 2tj                      

at t = 4:

v(4) = i + 8j

The acceleration is given by:  r"(t).

a(t) = r"(t) = 0i + 2j

The acceleration at t = 4 is:

a(4) = 0i + 2j

The double integral of (xy y^(-2)) over the region R is equal to 0.

What is double integral ?

The term integral in math is defined as a method of adding or summing up the parts to find the whole and it is basically used to find the volume, area and the central values of many things. Double integrals are a two-dimensional integration method.

The given expression is the integrand of a double integral over the region R defined by the constraints 0 ≤ x ≤ 2 and 0 ≤ y ≤ 2. To calculate this double integral, we would evaluate the following expression:

∬(xy y^(-2)) dA = ∬(xy y^(-2)) dx dy over the region R

We can evaluate this double integral using a change of variables, such as polar coordinates, or using rectangular coordinates.

In rectangular coordinates, we can evaluate the double integral using the following steps:

Evaluate the bounds of integration:

x: 0 to 2

y: 0 to 2

Evaluate the integral with respect to y first, keeping x fixed:

∬(xy y^(-2)) dx dy = ∫(x ∫(y y^(-2)) dy) dx, from 0 to 2

Evaluate the inner integral with respect to y:

∫(y y^(-2)) dy = -y^(-1) = -ln(y) + C, where C is an arbitrary constant

Substitute the solution for the inner integral back into the outer integral:

∫(x (-ln(y) + C)) dx = x(-ln(y)) - xC + D, where D is another arbitrary constant

Evaluate the outer integral with respect to x:

∫(x(-ln(y)) - xC + D) dx = (-x^2/2)ln(y) - (x^2/2)C + xD + E, where E is yet another arbitrary constant

Evaluate the constants of integration C, D, and E using the boundaries of integration for x and y:

-ln(2) - 0C + 0D + E = 0

-2ln(2) - 2^2/2 C + 2D + E = 0

Solving the system of equations, we find C = 2ln(2), D = 0, and E = 0

Substitute the values of C, D, and E back into the solution:

(-x^2/2)ln(y) - (x^2/2)C + xD + E = (-x^2/2)ln(y) - x^2ln(2)

Finally, evaluate the integral over the region R by substituting the bounds of integration for x and y:

(-2^2/2)ln(2) - 2^2ln(2) = -4ln(2) + 4ln(2) = 0

So, The double integral of (xy y^(-2)) over the region R is equal to 0.

The sample standard deviation is A. 5.9

What is Standard Deviation ?

It is a measure of how evenly distributed numbers are. It is the square root of the Variance, which is the average of the squared deviations from the Mean.

To find the sample standard deviation, first, we have to find the mean of the data, then subtract each data point from the mean, square each deviation, sum them, divide by the sample size minus 1, and then take the square root of the result.

Here's the calculation:

Mean = (1 + 5 + 12 + 16 + 15 + 12 + 19 + 5 + 10) / 9 = 11

Deviations = [-10, -6, 1, 5, 4, 1, 8, -6, -1]

Squared deviations = [100, 36, 1, 25, 16, 1, 64, 36, 1]

Sum of Squared deviations = 239

Sample Variance = Sum of Squared deviations / (Sample size - 1) = 239 / (9 - 1) = 239 / 8 = 29.875

[tex]Sample \ Standard\ Deviation=\sqrt{(Sample Variance)} \\\\Sample \ Standard\ Deviation=\sqrt{29.875}\\\\ Sample \ Standard\ Deviation= 5.9[/tex]

The fully factored form of the equation is 2x(x + 3) (2x - 1) that is option B.

Synthetic division and the rational root theorem can be used to demonstrate this. According to the rational root theorem, p must divide the constant term and q must divide the leading coefficient if p/q is a rational root of the polynomial f(x). The constant term in this example is -6, the leading coefficient is 4, and the potential rational roots are 1, 2, 3, and 6.

When we divide 4x3 + 10x2 - 6x by 2x - 1 using synthetic division, we arrive at the following result:

4x^3 + 10x^2 - 6x = (2x - 1) (2x^2 + 8x + 6)

We can then factor the remaining quadratic, 2x^2 + 8x + 6, as (x + 3)(2x + 2).

Thus, the completely factored form of 4x^3 + 10x^2 - 6x is:

It follows that continuity at infinity is provided by having the same limit while approaching it from either side, i.e., the limit towards + and, which makes sense based on your understanding.

When a function can be extended to P1, it is said to be "continuous at infinity" (R).

Calculus's idea of the limit describes how a function behaves as its input gets closer to a particular value. As long as the limit is present, the value that f(x) approaches as x moves closer to c is represented by the notation lim(x -> c) f(x), which stands for the limit of a function at the point x = c.

You must demonstrate that all three of the following conditions are true in order to prove that a function f is continuous on an interval:

Every point in the interval has f specified, and the interval has f's bound.

For each and every > 0, there is a corresponding > 0 such that |x - c| implies |f(x) - f(c)| for all x and all c in the interval.

F is considered to be continuous on the interval if these requirements are met.

The solution to the exponential inequality in this problem is given as follows:

x < 1.72.

The exponential inequality for this problem is defined as follows:

3^(4x - 5) < 8.

The number 8 is not a base of 3, hence the way to isolate the variable x is applying the log of base 3 to both sides, as follows:

log3(3^(4x - 5)) = log3(8)

4x - 5 = log3(8)

The logarithm of base 3 of 8 can be obtained applying the change of base property, as follows:

log3(8) = log(8)/log(3)

log3(8) = 1.893.

Normal Approximation to Binomial:

The normal distribution is used to approximate for the binomial distribution. The condition when binomial distribution is approximated to normal is that n should be large and probability should be close to 0.5

"Information available from the question"

n = 30

Probability, p(heads) = 1/2

Since sample size is large, we check for normal approximation.

np = 30(1/2) = 15

and, n(1 - p) = 30(1 - (1/2)) = 15 both are greater than 5, we use normal approximation.

Mean, μ = np = 30(1/2) = 15

Standard deviation, σ = [tex]\sqrt{np(1-p)}[/tex]

Standard deviation, σ = [tex]\sqrt{30(1/2)(1-1/2)}[/tex]

Standard deviation, σ =2.739

We have to find P (X ≥ 15). Using continuity correction, we deduct 0.5

P(X ≥ 15) = P(X > 14.5)

The respective Z-score with X = 14.5 is

Z = (x - μ)/ σ

Z = (14.5 - 15)/2.739

Z = -0.18
