Answer:

(1 - 0.2)s.

Step-by-step explanation:

It is given that a store is offering 20% off all shoes. Rosalie purchases shoes and clothes.

The expression representing her total cost (including 7% tax) is

c + (1 - 0.2)s + 0.07[c+ (1 - 0.2)s].

Here,

c = Cost of clothes

s = Cost of shoes

(1 - 0.2)s = cost of the shoes after the 20% discount.

0.07[c+ (1 - 0.2)s] = Amount of tax on total purchase of shoes and clothes.

Therefore, (1 - 0.2)s term represents the cost of the  shoes after the discount.

Answer:

A

Step-by-step explanation:

Gets Narrow, and opens opposite direction

Answer:

55 degrees

Step-by-step explanation:

Angle ACE and BDE are congruent so segments AC and BD are parallel.  That makes angles CAE and DBE congruent.

6x - 15 = 5x - 1

x - 15 = -1

x = 14

So, the measure of angle BDE = 4x = 56 degrees.  The measure of angle DBE = 5x - 1 = 69 degrees.

The total of all angles in triangle BDE is 180 degrees, so the measure of angle E = 180 - 56 - 69 = 55

\(\text{We know that,}\\\\\cos \theta = \dfrac{\text{Base}}{\text{Hypotenuse}}\\\\\\\text{For}~ \angle1,\\\\~~~~~~\cos \angle 1 = \dfrac bc\\\\\\\implies \cos \angle 1 = \dfrac 35\\\\\\\implies \angle 1 = \cos^{-1} \left( \dfrac 35 \right)\\\\\\\implies \angle 1 = 53.13^{\circ}\\\\\\\text{For} ~ \angle 2,\\\\~~~~~~~\cos \angle 2 = \dfrac ac\\\\\\\)

\(\implies \cos \angle 2 = \dfrac 45\\\\\\\implies \angle 2 =\cos^{-1} \left( \dfrac 45 \right)\\ \\\\\implies \angle 2 = 36.86^{\circ}\)

\(\text{Hence,}~~ m\angle 1 = 53.13^{\circ}~~ \text{and}~~ m\angle 2 =36.86^{\circ}.\)

An equation that represents the line is:

y = 3/4x - 9/2

Step-by-step explanation:

The slope-intercept form of the line equation

\(y = mx+b\)

where

Given the attached graph of a line.

Taking two points from the line, such as

Determining the slope between (2, -3) and (0, 6)

\(\left(x_1,\:y_1\right)=\left(2,\:-3\right),\:\left(x_2,\:y_2\right)=\left(6,\:0\right)\)

\(m=\frac{0-\left(-3\right)}{6-2}\)

refine

\(m=\frac{3}{4}\)

substituting m = 3/4 and the point (2, -3) in the slope-intercept form of the line equation

y = mx + b

\(\left(-3\right)=\frac{3}{4}\left(2\right)+b\)

\(\frac{3}{2}+b=-3\)

subtract 3/2 from both sides

\(\frac{3}{2}+b-\frac{3}{2}=-3-\frac{3}{2}\)

\(b=-\frac{9}{2}\)

now substituting b = -9/2 and m = 3/4 in the slope-intercept form of the line equation

y = mx + b

y = 3/4x + (-9/2)

Therefore, an equation that represents the line is:

y = 3/4x - 9/2

Composition of functions is when one function is used as the input for another function.

Composition of functions is the process of combining two functions to form a new one. An example of this is the combination of the functions f(x) = x2 and g(x) = x+1. The new function created by this composition is given by h(x) = (x+1)2. This can be expressed in formula form as h(x) = f(g(x)).  For example, let’s say we have two functions, f(x) = x + 1 and g(x) = x2. We can find the composition of these two functions, f(g(x)), which would be equal to x2 + 1. This can be written as f(g(x)) = (x2 + 1). We can also calculate this composition. If x = 2, then f(g(2)) = 22 + 1 = 5. As another example, if we have h(x) = x3 and i(x) = 3x2, then the composition h(i(x)) = (3x2)3 = 27x6. For x = 2, then h(i(2)) = 272 = 729. As these examples show, composition of functions is a powerful tool in mathematics that can be used to quickly calculate complex equations

a. The probability of success (hitting the target) is constant for each trial (88% or 0.88).

b. The probability of hitting the 6th target is:

P(X = 1) = C(1, 1) * 0.88^1 * (1 - 0.88)^(1 - 1) = 0.88

c. Using the binomial probability formula as before, with p = 0.88 and n = 3:

P(X = 1) = C(3, 1) * 0.88^1 * (1 - 0.88)^(3 - 1)

P(X = 2) = C(3, 2) * 0.88^2 * (1 - 0.88)^(3 - 2)

P(X = 3) = C(3, 3) * 0.88^3 * (1 - 0.88)^(3 - 3)

a) The three characteristics of this scenario that indicate we are working with Bernoulli trials are:

The experiment consists of a fixed number of trials (eight shots).

Each trial (shot) has two possible outcomes: hitting the target or missing the target.

The probability of success (hitting the target) is constant for each trial (88% or 0.88).

b) To find the probability of hitting the 6th target (considered as a single trial), we can use the binomial probability formula:

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

where:

P(X = k) is the probability of getting exactly k successes,

C(n, k) is the binomial coefficient or number of ways to choose k successes out of n trials,

p is the probability of success in a single trial, and

n is the total number of trials.

In this case, k = 1 (hitting the target once), p = 0.88, and n = 1. Therefore, the probability of hitting the 6th target is:

P(X = 1) = C(1, 1) * 0.88^1 * (1 - 0.88)^(1 - 1) = 0.88

c) To find the probability that the first time hitting the target is not until the 4th shot, we need to consider the complementary event. The complementary event is hitting the target before the 4th shot.

P(not hitting until the 4th shot) = P(hitting on the 4th shot or later) = 1 - P(hitting on or before the 3rd shot)

The probability of hitting on or before the 3rd shot is the sum of the probabilities of hitting on the 1st, 2nd, and 3rd shots:

P(hitting on or before the 3rd shot) = P(X ≤ 3) = P(X = 1) + P(X = 2) + P(X = 3)

Using the binomial probability formula as before, with p = 0.88 and n = 3:

P(X = 1) = C(3, 1) * 0.88^1 * (1 - 0.88)^(3 - 1)

P(X = 2) = C(3, 2) * 0.88^2 * (1 - 0.88)^(3 - 2)

P(X = 3) = C(3, 3) * 0.88^3 * (1 - 0.88)^(3 - 3)

Calculate these probabilities and sum them up to find P(hitting on or before the 3rd shot), and then subtract from 1 to find the desired probability.

The magnitude of the moment about the y-axis is the absolute value of the y-component, which is 320.

Option B is the correct answer.

We have,

The position vector is given by the coordinates of the point of application of the force, which is (4,-6,4).

So, the position vector r.

r = <4, -6, 4>

Next, we need to find the cross product of the position vector r and the force vector F to get the moment vector M.

The moment vector.

M = r x F

where x denotes the cross product.

We are given the x and y components of the force, but not the z component.

However, we know that the magnitude of the force is 500, which means that:

|F| = sqrt(Fx^2 + Fy^2 + Fz^2) = 500

Substituting Fx and Fy in the equation above, we get:

sqrt(300^2 + 200^2 + Fz^2) = 500

Simplifying, we get:

Fz^2 = 120000

Fz = 346.41 (approx)

The force vector.

F = <300, 200, 346.41>

Now, we can calculate the moment vector M as follows:

M = r x F

= <4, -6, 4> x <300, 200, 346.41>

= <-800, 320, -200>

The moment vector has components of -800, 320, and -200 along the

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

Suppose that the number in consideration be N

Then, we get:

Increased number = N + 50% of N

Since 50% of N is: ,

thus, the increased number = N + N/2 = 3N/2

Now this result is decreased by 50%

Decreased number = result - 50% of  result

Since 50% of result is:

Thus, Decreased number = 3N/2 - 3N/4 = 3N/4

Let us suppose that the original number N is decreased y% to get 3N/4(the final number)

Then,

3N/4 = N - y% of N

y% of N is calculated as:

The 90 % confidence interval is ( 19.92 , 20.18 )

A confidence interval is defined as the range of values that we observe in our sample and for which we expect to find the value that accurately reflects the population.

The relationship between a value and the mean of a set of values is expressed numerically by a Z-score. The Z-score is computed using the standard deviations from the mean. A Z-score of zero indicates that the data point's score and the mean score are identical.

The Z-score is calculated using the formula:

z = (x - μ)/σ

where z: standard score

x: observed value

μ: mean of the sample

σ: standard deviation of the sample

Given data ,

Let the number of samples n = 15

Let the mean of the sample be μ = 20.05

Let the standard deviation σ = 0.3

Now , the z score of 90 % confidence interval is z = 1.645

The 90% confidence interval is calculated by the equation

A = μ ± z ( σ / √n )

Substituting the values in the equation , we get

P = μ + z ( σ / √n )

Q = μ - z ( σ / √n )

Now , the value of P is

P = 20.05 + 1.645 ( 0.3/√15 )
