high school students on various sports teams. The study includes a survey composed of 5 statements to which students
respond on a scale of 1-5. A response of 5 indicates strong agreement with the statement and a response of 1 indicates
strong disagreement with the statement. The results of the statement, "Participating in a sport helps to improve a person's
ability to prioritize his or her free time," shows an average response score of 3.2 and a standard deviation of 1.2. One
conclusion in the report of the study states that participation in sports markedly improves a student's ability to make good use
of free time.

Which statements regarding the report are true?

Select each correct answer.

A)The report should be considered accurate only if the sample is a stratified sample of students playing sports.
The study is biased since the survey includes only students playing a sport so the report should not be considered

The value of the angle a is 38⁰

The value of the angle b is 52⁰

The value of the angle c is 104⁰

The value of the angle d is 90⁰

The value of the angles is calculated by applying intersecting chord theorem, which states that the angle at tangent is half of the arc angle of the two intersecting chords.

a = ¹/₂ x arc 76⁰

a = 38⁰

Since the chord passed through the center, arc c is calculated as;

arc c = 180 - 76 (sum of angles of a semicircle)

arc c = 104⁰

b = ¹/₂ x 104⁰

b = 52⁰

d = 180 - (a + b) (sum of angles in a triangle)

d = 180 - (38 + 52)

d = 90⁰

First, let us calculate the amount of rubber and steel belts required for the production of passenger car and truck tires.

Passenger car tires,

Rubber,

66,000 tires x 33 lb. per unit = 2,178,000 lb.

Steel belts,

66,000 tires x 5 lb. per unit = 330,000 lb.

Truck tires,

Rubber,

20,000 tires x 77 lb. per unit = 1,540,000 lb.

Steel belts,

20,000 tires x 13 lb. per unit = 260,000 lb.

Next, let us calculate the total amount of rubber and steel belts needed for production.

Rubber,

2,178,000 lb. + 1,540,000 lb. = 3,718,000 lb.

Steel belts,

330,000 lb. + 260,000 lb. = 590,000 lb.

To calculate the total amount of rubber and steel belts required for purchase,

Add the desired ending inventories and subtract the estimated beginning inventories,

Rubber,

3,718,000 lb. + 62,000 lb. - 73,000 lb. = 3,707,000 lb.

Steel belts,

590,000 lb. + 13,000 lb. - 11,000 lb. = 592,000 lb.

Finally, calculate the total cost of rubber and steel belt purchases.

Rubber,

3,707,000 lb. x $2.90 per pound = $10,749,300

Steel belts,

592,000 lb. x $3.80 per pound = $2,249,600

Answer:

Step-by-step explanation:

To differentiate y = 3x cos(x) + sin(x), we can use the product rule and the chain rule.

Let's start by differentiating the first term, 3x cos(x), using the product rule:

d/dx (3x cos(x)) = 3 cos(x) - 3x sin(x)

Next, we can differentiate the second term, sin(x), using the chain rule:

d/dx (sin(x)) = cos(x)

Putting it all together, we get:

dy/dx = 3 cos(x) - 3x sin(x) + cos(x)

Simplifying the expression, we get:

dy/dx = (4cos(x)) - (3xsin(x))

Therefore, the derivative of y = 3x cos(x) + sin(x) is dy/dx = 4cos(x) - 3xsin(x).

Answer:

We can use the proportion method to solve this problem.

Let's define the rate of dough preparation as the amount of dough Lia can prepare per hour. We can write:

rate = amount of dough / time

We are given that Lia prepared 35 kg of dough in 7 hours. We can use this information to find her rate of dough preparation:

rate = 35 kg / 7 hours = 5 kg/hour

Now we can use this rate to find how much dough Lia will prepare if she works for 9 hours:

amount of dough = rate x time

amount of dough = 5 kg/hour x 9 hours = 45 kg

Therefore, if Lia works for 9 hours, she will prepare 45 kilograms of dough.

Robert can make a maximum of 8 milkshakes with the remaining chocolate syrup.

Converting the mixed number 2 2/5 to an improper fraction: 2 2/5 = 12/5

Subtracting the amount of chocolate syrup used per milkshake from the total amount of chocolate syrup:

12/5 - 1/4 = (48 - 5) / 20 = 43/20

Therefore, Robert has 43/20 cups of chocolate syrup left, which is the maximum amount he can use to make milkshakes.

For maximum number of milkshakes:

(43/20) / (1/4) = (43/20) x (4/1) = 172/20 = 8.6

Since Robert cannot make a fraction of a milkshake, he can make a maximum of 8 milkshakes with the remaining chocolate syrup.

The rectangle's circumference is 27+ (3/2) fee and one of its sides is a semicircle.

We can start by finding the perimeter of the rectangle, which is simply the sum of the lengths of all four sides:

Perimeter of rectangle = 2(length + width) = 2(12 + 3) = 30 feet

Next, we need to find the perimeter of the semicircle.

The diameter of the semicircle is equal to the width of the rectangle, which is 3 feet. The formula for the perimeter of a semicircle is:

Perimeter of semicircle = (π/2) x diameter + diameter

Plugging in the values, we get:

Perimeter of semicircle = (π/2) x 3 + 3 = (3/2)π + 3

Now, we can add the perimeter of the semicircle to the perimeter of the rectangle to get the total perimeter:

Total perimeter = Perimeter of rectangle + Perimeter of the semicircle- 2*diameter of the semicircle

= 30 + (3/2)π + 3 - 3*2

= 27+ (3/2)π

So θ=−7π4, and r must be positive, as the angle is measured from the positive x axis. Thus, the polar coordinates are (1,−7π4).

The equation of line is,

⇒ y = 1/2x + 2

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (- 4, 0) and (0, 2).

Now,

Since, The equation of line passes through the points (- 4, 0) and (0, 2).

So, We need to find the slope of the line.

The value that would help Charlie find out how long it takes his basketball to reach the highest point is "x at the vertex". The correct option is A.

When the basketball reaches the highest point, its vertical velocity is zero. The time taken to reach this point can be found using the equation:

t = -b / (2a)

where a is the acceleration due to gravity (-9.8 m/s²) and b is the initial vertical velocity of the basketball.

The vertex of the parabolic path that the basketball follows is the point where the basketball reaches its maximum height. This point occurs at the halfway point of the ball's total flight time. The horizontal distance the basketball travels during this time is called "Ox at the vertex".

Therefore, by finding the "x at the vertex", Charlie can calculate the total flight time of the basketball, and then use the equation above to find the time it takes to reach the highest point.
