WHAT IS IMPLENTATION?

What do you mean implementation?

Implementation is the execution or practice of a plan, a method or any design, idea, model, specification, standard or policy for doing something. As such, implementation is the action that must follow any preliminary thinking for something to actually happen.

From the complete question, we have the following parameters:

Unit rate = $8.00

Total pounds = 100

Total cost of chocolate sprinkles

So, the total cost of chocolate sprinkles is calculated using the following formula

Multiply both sides of the equations by 100

We can be 99% confident that the true difference between the proportion of men and women who favor Mr. Singleton as a candidate is between 0.059 and 0.219.

Step 1: Determine the values of the \(\mathrm{\hat p_1}\) and \(\mathrm{\hat p_2}\) sample proportions.

The percentage of men who, on average, support Mr. Singleton is:

\(\mathrm{\hat p_1}\)  = \(\dfrac{282}{659}\), or around 0.428

The percentage of women who favour Mr. Singleton, as a sample, is:

\(\mathrm{\hat p_2}\) = \(\dfrac{182}{629}\), or around 0.289

Locate the critical value that must be utilised to build the confidence interval in step 2.

The level of significance is \(\alpha\) = 0.01/2 = 0.005 (divided by 2 because it's a two-tailed test) because we want to determine a 99% confidence interval. The critical value for a z-score with  \(\alpha\) = 0.005 is roughly 2.576 when using a table or calculator.

Step 3: Determine the standard error's value.

The standard error of the difference between two sample proportions is calculated as follows:

\(\mathrm{(\Hat p 2-\Hat p 2) + n_1 + \frac {\hat p_2}{1}}\)

When we enter the values from the issue, we obtain:

\(\mathrm{SE = \sqrt{\dfrac{\hatp_1}{SE}} = (\hat p_1 - \hat p_2) (\hat p_1 - \hat p_1) }\)

Create the 99% confidence interval in step four.

We may create the confidence interval using the sample proportions, critical value, and standard error:

\(\mathrm{SE(\hat p_1 - \hat p_2) 1:00 \ p.m. \ to \ 2:00 \ p.m. \ z \ \alpha \ 2}\)

When we change the values, we obtain:

2.576, × 0.031, = (0.428 - 0.289).

If we simplify, we get:

\($$0.139 \pm \ 0.08$$\).

3. Find the value of the standard error.

The following formula is used to compute the standard error of the difference between two sample proportions:

\(\mathrm{SE = \sqrt{\dfrac{\hatp_1}{SE}} = (\hat p_1 - \hat p_2) (\hat p_1 - \hat p_1) }\)

\(\mathrm{(\Hat p 2-\Hat p 2) + n_1 + \frac {\hat p_2}{1}}\)

When we type in the issue's values, we get:

\($ \mathrm{\sqrt{(\frac{1-0.428}{0.659}) + \frac{1-0.288}{0.629}) }= about \ 0.031 \ for \ SE (\hat p_1 - \hat p_2)}\)

In step four, calculate the 99% confidence interval.

With the sample proportions, critical value, and standard error, we can calculate the confidence interval:

\(\mathrm{SE(\hat p_1 - \hat p_2) 1:00 \ p.m. \ to \ 2:00 \ p.m. \ z \ \alpha \ 2}\)

When the values are changed, we get the following result: \($2.576 \times 0.031 = (0.428 - 0.289)$$\)

Simplifying, we obtain: \($$0.139 \pm \ 0.08$$\).

Answer:

Answers B and D

Step-by-step explanation:

The side lengths must satisfy the Pythagorean Theorem:  a² + b² = c²

Note that in Answer D, 3² + 4² = 5² (or 9 + 16 = 25).

Also:  In Answer B, (3√2)² + 3√2)² = 6² (or 18 + 18 = 36)

Answer:

option B

Step-by-step explanation:

since two two angles are 45 degree it can be said that the other two smaller legs of a triangle are equal.

Hypotenuse is 90 degree because it is opposite of 90 degree (which is a largest angle).

out of these four options A and B are the possible answers.because its two sides are equal. Now we should check which one is correct by using pythagoras theorem.

for option A

a^2 + b^2 = c^2

\((\frac{\sqrt{3} }{2} )^2\) +\((\frac{\sqrt{3} }{2})^2\) = \(\sqrt{\sqrt{2} }\)

\(\frac{3}{4} + \frac{3}{4} = 2\)

take lcm of denominator

\(\frac{3+3}{4} =2\)

\(\frac{6}{4}=2\)

\(\frac{3}{2 } =2\)

this can not be the sides of the right angle because according to the pythagoras theorem to be the right angle sum of square of two smaller sides of a triangle must equal to the square of hypotenuse .But here it is not equal.so it cannot be the sides of right angle triangle.

For option B

a^2 + b^2 = c^2

\((3\sqrt{2} )^2 + (3\sqrt{2})^2 = 6^2\)

\(3*3*2 + 3*3*2 =36\)

\(18 + 18 =36\)

\(36 = 36\)

since both sides are equal it satisfies the pythagoras theorem.

therefore answer is option B.

Answer:

f^ - 1 (x) = x/3 + 1/3​ is not the inverse function of f(x) = 3x + 1

Step-by-step explanation:

F(x) = 3x + 1

Inverse:

x = 3y + 1

3y = x - 1

y = x/3 - 1/3 or f^ - 1 (x) = x/3 - 1/3​

so

f^ - 1 (x) = x/3 + 1/3​ is not the inverse function of f(x) = 3x + 1

Answer:

$70.

Step-by-step explanation:

Since Neda sells televisions, and she earns a fixed amount for each television and an additional $ 15 if the buyer gets an extended warranty, if Neda sold 19 televisions with extended warranties and earned $ 1,615, to determine how much is the fixed amount Neda earns for each television must perform the following calculation:

(19 x 15) + X = 1615

285 + X = 1615

X = 1330

1330/19 = 70

Thus, the fixed amount Neda receives for each television is $70.

Answer: $70

Step-by-step explanation:

Since Neda sells televisions, and she earns a fixed amount for each television and an additional $ 15 if the buyer gets an extended warranty, if Neda sold 19 televisions with extended warranties and earned $ 1,615, to determine how much is the fixed amount Neda earns for each television must perform the following calculation:

(19 x 15) + X = 1615

285 + X = 1615

After this step, you can see that the x is already isolated and no number next to it. This is a good thing because you only need to subtract 285 on both sides.

x = 1330

Then...

1330/19 = 70.
Thus, the fixed amount Neda receives for each television is $70.

Answer:

Option (2)

Step-by-step explanation:

In this question we have to calculate the rate of earning or proportionality constant of Abigail.

Since, earning of Abigail (y) ∝ Time worked (t)

y = kt

Here, k = Proportionality constant

From the table attached,

If y = $709.80 and x = 21 hours

709.80 = 21k

k = \(\frac{709.8}{21}\)

k = $33.80 per hour

Therefore, rat of earning or proportionality constant is $33.80

Option (2) will be the correct option.

To find arcsin, we need to use the identity:

sin(arcsin(x)) = x

Since arcsin is negative, sin(arcsin) is also negative. Therefore, we can say:

sin(arcsin) = -sqrt(1 - (cos)^2)

where (cos)^2 = 8/17

Substituting, we get:

sin(arcsin) = -sqrt(1 - (8/17))

Simplifying, we get:

sin(arcsin) = -sqrt(17/17 - 8/17)

Simplifying further, we get:

sin(arcsin) = -sqrt(9/17)

Therefore, arcsin = -sqrt(9/17)

To find arctan, we need to use the identity:

tan(arctan(x)) = x

Substituting, we get:

tan(arctan) = -8/17

Therefore, arctan = -8/17

So, arcsin is -sqrt(9/17) and arctan is -8/17.

Based on the information in the image, it can be inferred that the sides of the box measure 5 cm each.

To find the measure of the sides of the box we must carry out the following mathematical procedure:

As we know the volume of a cube is the equivalent to the length of its sides raised to the cube (raised to the 3). In this case, to identify the value of the sides we must find the cube root of the volume and the result is the length of the sides.

So this cube has a volume of 125cm³, so its sides would be the cube root of 125.

\(\sqrt[3]{125} = 5\)

According to the above, the length of the sides is 5 taking into account that all the sides are equal.

y = kx

Where:

Next, we would determine the constant of proportionality (k) by using various data points as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k = 3/10 = 6/20 = 9/30

Constant of proportionality, k = 3/10.

Therefore, the required linear equation is given by;

11^2 must be equal to 4^2 + 7^2

11^ = 121

4^2 + 7^2 = 16 + 49 = 65
