Rachel will have ran 114 miles in six weeks.

There's five weekdays in a week: (3.2 x 5) = 16 miles

There's two days in a weekend: (1.5 x 2) = 3 miles

16 [weekday] + 3 [weekend] = 19 miles [7-day week]

8=8 Correct

Answer:

The answer is 576 inches

Answer:

E

Step-by-step explanation:

using the Sine rule in Δ ABC

\(\frac{a}{sinA}\) = \(\frac{b}{sinB}\) = \(\frac{c}{sinC}\)

where a is the side opposite ∠ A , b opposite ∠ B , c opposite ∠ C

we require to calculate ∠ C

∠ C = 180° - (64 + 85)° = 180° - 149° = 31°

then to find a , using

\(\frac{a}{sinA}\) = \(\frac{c}{sinC}\)

\(\frac{a}{sin64}\) = \(\frac{9.3}{sin31}\) ( cross- multiply )

a × sin31° = 9.3 × sin64° ( divide both sides by sin31° )

a = \(\frac{9.3sin64}{sin31}\) ≈ 16.23 ( to 2 decimal places )

then to find b , using

\(\frac{b}{sinB}\) = \(\frac{c}{sinC}\)

\(\frac{b}{sin85}\) = \(\frac{9.3}{sin31}\) ( cross- multiply )

b × sin31° = 9.3 × sin85° ( divide both sides by sin31° )

b = \(\frac{9.3sin85}{sin31}\) ≈ 17.99 ( to 2 decimal places )

m∠NOP = 90° is the value of angle .

What does a math angle mean?

An angle is made up of two rays (half-lines) that have a shared termination. The rays serve as the angle's sides, occasionally serving as the angle's legs and occasionally serving as its arms, while the latter is referred to as the vertex of the angle.

                                           A figure that is created by two rays or lines that have the same endpoint is known as an angle in plane geometry. The Latin word "angulus," which meaning "corner," is the source of the English term "angle". The vertex, which is the shared terminal of the two rays, is referred to as the side of an angle.

The measure of angle A'B'C' in the resulting figure is approximately 142.6 degrees.

The reflection of a point (x, y) across the y-axis is (-x, y). Applying this transformation to the coordinates of A, B, and C, we get:

A' (-2, 1)

B' (-6, 1)

C' (-6, 4)

The rotation of a point (x, y) by 180 degrees counter clockwise is (-x, -y). Applying this transformation to the coordinates of A', B', and C', we get:

A'' (2, -1)

B'' (6, -1)

C'' (6, -4)

Next, we can use the law of cosines to find the measure of angle B:

Answer:

The regression model is:

y = 20.29 + 0.73·x

Step-by-step explanation:

In this case a regression model is to be formed to predict the final average in the course based on the first test grade.

Use Excel to form the regression model.

The output is attached below.

The regression model is:

y = 20.29 + 0.73·x

Predict the final average of a students who made an 83 on the first test as follows:

y = 20.29 + 0.73·x

  = 20.29 + 0.73 × 83

  = 80.88

The final average of a students who made an 83 on the first test would be 80.88.

From the output:

R² = 0.839

Then the correlation coefficient will be:

\(r=\sqrt{R^{2}}=\sqrt{0.839}=0.91597\approx 0.92\)

The value of r is 0.92.

The coefficient of determination R² specifies the percentage of the variance in the dependent-variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent-variable).

In this case, the R² value of 0.839 implies that 83.9% of the variation in the final average can be explained by the grades in the first test.

For the fractions, the calculation of 3/5 of 2/3 of 3/4 of 560 is equal to 168.

To calculate 3/5 of 2/3 of 3/4 of 560, break it down step by step:

Step 1: Calculate 3/4 of 560:

3/4 × 560 = (3 × 560) / 4 = 1680 / 4 = 420

Step 2: Calculate 2/3 of the result from Step 1:

2/3 × 420 = (2 × 420) / 3 = 840 / 3 = 280

Step 3: Calculate 3/5 of the result from Step 2:

3/5 × 280 = (3 × 280) / 5 = 840 / 5 = 168

Therefore, 3/5 of 2/3 of 3/4 of 560 is equal to 168.

Answer:

34.8 N at 2.5 degrees from the positive x-axis

Step-by-step explanation:

From the given information:

The force F makes an angle A with the positive x axis can be expressed in terms horizontal and vertical components.

\(F_x = F cos A\\\\ F_y = Fsin A\)

Given that

\(F_1 = 50 \ N\)

\(\theta_1 = 30 ^0 \ \ \ (x-axis)\)

\(F_{1x} = F_1 \times Cos A_1\)

=  50 × cos 30

= 43.3 N

\(F_{1y} = F_1 \times Sin \ A_1\)

= 50 × sin 30

= 25 N

Similarly;

\(F_2 = 25 \ N\)

\(\theta_2 = 250 ^0 \ \ \ ( x-axis)\)

\(F_{2x} = F_2 \times cos \ A_2\)

= 25 × cos 250

= - 8.55 N

\(F_{2y} = F_2 \times A_2\)

= 25 × sin 250

= -23.5 N

The total net force;

\(F_{net} = F_{(net)}_x + F_{(net)}_y\)

\(F_{net} = (F_{1x} + F_{2x} ) i + (F_{1y} + F_{2y} )j\)

\(F_{net} = (43.3 - 8.55) i + (25-23.5 ) j\)

\(F_{net} =34.75 i + 1.5 j\)

\(|F_{net} | = \sqrt{F_{net}_x^2 + F_{net}_y^2}\)

\(|F_{net} | = \sqrt{34.75^2 + 1.5^2}\)

\(|F_{net} | = 34.8 \ N\)

Finally, the direction of the angle for the net force is:

\(tan \theta = \dfrac{F_{net_y}}{F_{net_x}}\)

\(\theta = tan^{-1} \Big (\dfrac{F_{net_y}}{F_{net_x}} \Big)\)

\(\theta = tan^{-1} \Big (\dfrac{1.5}{34.75}} \Big)\)

\(\theta = tan^{-1}( 0.043165)\)

\(\theta \simeq 2.5^0\ with \ positive \ x-axis\)

In the given question,

We have to explain which of the following is unlikely to be a primary building block in a company's organizational structure.

Organizational structures can be tailored to fit the needs of companies in certain sizes and industries by using functions, markets, products, regions, or processes as their guides.

According to your company's demands, you can add additional building blocks or components to an organisational structure, which normally comprises four basic components.

The value chain framework consists of four secondary activities, procurement and purchasing, human resource management, technological development, and business infrastructure, in addition to five primary activities: inbound operations, operations, outbound logistics, marketing and sales, and service.

The sampling method used by the restaurant manager allows for efficient data collection and a representative sample, it may introduce bias and lacks randomization.

Based on the information provided, we can identify the following statements that are true about the sampling method used by the restaurant manager to evaluate customer satisfaction with the new smoothie:

1. The manager uses systematic sampling: The manager surveys every other customer who orders the new smoothie. This systematic approach involves selecting every second customer, providing a consistent and organized sampling method.

2. The sample is representative: By surveying every other customer who orders the new smoothie, the manager ensures that the sample includes a variety of customers, reflecting the customer population as a whole.

3. The sample size may be smaller than the total customer base: Since the manager surveys every other customer, the sample size may be smaller compared to surveying every customer. This allows for efficient data collection and analysis.

4.The sampling method may introduce bias: The manager may inadvertently introduce bias by only surveying every other customer. Customers who are skipped in the survey may have different preferences or opinions, leading to a potential bias in the results.

5. The sampling method lacks randomization: Randomization is not employed in this sampling method, as the manager systematically selects customers. This could potentially introduce bias or exclude certain types of customers from the sample.
