Answer: 3.5 cm

Step-by-step explanation:

SA for cone = \(\pi\)rs + \(\pi\)r²        r=radius=9     s=slant height (not height)

A(cone) = 9\(\pi\)s + 81\(\pi\)

SA for a cylinder = 2\(\pi\)rh +2\(\pi r^{2}\)      r=6     h = 18

A(cyl) = 2(\(\pi\))(6)(8) + 2(\(\pi\))6²

           = 96\(\pi\) + 72\(\pi\)

           =168\(\pi\)

Set the 2 areas equal to each other to solve for slant height

9\(\pi\)s + 81\(\pi\) = 168\(\pi\)

9\(\pi\)s=87\(\pi\)

s=87/9

this is slant height, now you use pythagorean to solve for h

(87/9)²=9²+h²

h=3.5

If the length of the tube is 84.5cm and the diameter of the tube is 2.40 cm, then area of poster is 636.7 cm² ~ 637 cm²

Given that ;

Length of the cylinder = 84.5 cm

Diameter of the cylinder = 2.40 cm

Then the radius is 1.20 cm

When the poster is uncurled it is in rectangle shape so, length of the poster is 84.5cm.

When poster is curled in cylinder, circumference of circle is breadth of poster = 2πr = 2(22/7)1.2 = 7.53 cm

So the area of poster is length × breadth

Area = 84.5cm × 7.53cm

Area = 636.7 cm²

Hence the area of poster is 636.7 cm² ~ 637 cm²

If today it was sunny in the morning and raining in the afternoon, and Laura traveled a total of 24 km in 40 minutes, then she is calculated to have rode the electric scooter for  24 minutes in the afternoon.

Let's assume that Laura rode her scooter for x minutes in the morning and for (40 - x) minutes in the afternoon.

In the morning, she traveled a distance of 45 × (x/60) km.

In the afternoon, she traveled a distance of 30 × ((40-x)/60) km.

The total distance traveled is 24 km, so we can set up the equation:

45 × (x/60) + 30 × ((40-x)/60) = 24

Multiplying both sides by 60, we get:

45x + 30(40-x) = 1440

Simplifying and solving for x, we get:

15x + 1200 = 1440

15x = 240

x = 16

Therefore, Laura rode her scooter for (40-16) = 24 minutes in the afternoon.

The quadrants that satisfy the condition xy > 0 are quadrant I and quadrant III.

Quadrant I is the top-right quadrant, where both the x-coordinate and y-coordinate are positive. In this quadrant, the product of x and y will also be positive, since two positive numbers multiplied together always result in a positive number.

Quadrant III is the bottom-left quadrant, where both the x-coordinate and y-coordinate are negative. In this quadrant, the product of x and y will also be positive, since two negative numbers multiplied together also result in a positive number.

Quadrants II and IV do not satisfy the condition, since in quadrant II, the x-coordinate is negative while the y-coordinate is positive, resulting in a negative product. Similarly, in quadrant IV, the x-coordinate is positive while the y-coordinate is negative, also resulting in a negative product.

Answer:

We can begin by finding the slope of the line 3x+4y=3 by rearranging it into slope-intercept form, y=mx+b:

4y = -3x + 3

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

Thus, the slope of this line is -3/4.

Since the line y=mx+8 intersects the first line at a 45° angle, we know that the product of their slopes must be -1 (since the tangent of a 45° angle is 1). Therefore, we can set up the equation:

(-3/4)(m) = -1

Solving for m, we get:

m = 4/3

Therefore, the value of m that would make y=mx+8 intersect the line 3x+4y=3 at a 45° angle is 4/3.

The solution to the system is x = 2 and y = 6, represented as the ordered pair (2, 6). This corresponds to option (B) in the answer choices.

To solve the system using substitution, we'll substitute the value of one variable from one equation into the other equation and solve for the remaining variable.

Given the system:

x + y = 8

y = 3x

Substituting the value of y from the second equation into the first equation, we have:

x + (3x) = 8

4x = 8

x = 2

Now, substitute the value of x into the second equation to solve for y:

y = 3(2)

y = 6

Therefore, the solution to the system is (2, 6). Option (B) is the correct answer.

The correct option is statistical inference (b).

The professor uses sample data from the population to determine the average age. Anytime inferential statistics or statistical inference is used to make inferences from samples.

Instead of gathering data from the entire institution, the professor took age samples from a class and used those data to draw conclusions about the entire university.

Descriptive statistics in statistics help you describe the facts, whereas inferential statistics assist you in drawing conclusions from the data.

Data from the sample are used in inferential statistics, which allows you to generalise about the population.

Inference generally refers to "guessing," which involves drawing conclusions about something.

So, drawing conclusions about the population is what is meant by statistical inference. It makes use of a number of statistical analytic tools to draw a conclusion about the population.

If MSwithin is smaller than MSbetween, then increasing MSwithin and/or decreasing MSbetween will lead to an increase in the F statistic.

The F statistic is calculated by dividing the variance between groups (MSbetween) by the variance within groups (MSwithin). Therefore, to increase the value of the F statistic, either the numerator (MSbetween) needs to increase, or the denominator (MSwithin) needs to decrease.

So, the answer is:

a. MSwithin > MSbetween

If the variance within groups (MSwithin) is reduced or the variance between groups (MSbetween) is increased, the F statistic will increase. Therefore, if MSwithin is smaller than MSbetween, then increasing MSwithin and/or decreasing MSbetween will lead to an increase in the F statistic.

The null hypothesis is always a statement about the population parameter or the absence of a relationship or difference between variables in a statistical hypothesis test. It is typically denoted as "H0" and assumes no effect or no difference exists.

The null hypothesis can take different forms depending on the specific research question. For example, in a study comparing the mean scores of two groups, the null hypothesis might state that the means are equal. In a correlation study, the null hypothesis could assert that there is no correlation between variables.

The null hypothesis acts as a baseline for comparison in hypothesis testing. Researchers aim to gather evidence against the null hypothesis to support an alternative hypothesis. Statistical analysis helps determine the likelihood of observing the obtained data if the null hypothesis were true.

By specifying a null hypothesis, researchers can objectively evaluate the evidence and draw conclusions about the relationship or difference they are investigating.

In summary, the null hypothesis is a statement about the population parameter or lack of relationship/difference, which serves as a reference point for hypothesis testing. It helps researchers assess evidence and draw conclusions based on statistical analysis.

Answer:

x = 71/8

Step-by-step explanation:

Solve for x:

2 (x - (3 + 1/2)) = 10 + 3/4

Put 3 + 1/2 over the common denominator 2. 3 + 1/2 = (2×3)/2 + 1/2:

2 (x - (7/2)) = 10 + 3/4

2×3 = 6:

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

6/2 + 1/2 = (6 + 1)/2:

2 (x - (7/2)) = 10 + 3/4

6 + 1 = 7:

2 (x - 1/2 7) = 10 + 3/4

Put each term in x - 7/2 over the common denominator 2: x - 7/2 = (2 x)/2 - 7/2:

2 ((2 x)/2 - 7/2) = 10 + 3/4

(2 x)/2 - 7/2 = (2 x - 7)/2:

2 (1/2 (2 x - 7)) = 10 + 3/4

(2 (2 x - 7))/2 = 2/2×(2 x - 7) = 2 x - 7:

(2 x - 7) = 10 + 3/4

Put 10 + 3/4 over the common denominator 4. 10 + 3/4 = (4×10)/4 + 3/4:

2 x - 7 = ((4×10)/4 + 3/4)

4×10 = 40:

2 x - 7 = 40/4 + 3/4

40/4 + 3/4 = (40 + 3)/4:

2 x - 7 = ((40 + 3)/4)

40 + 3 = 43:

2 x - 7 = 43/4

Add 7 to both sides:

2 x + (7 - 7) = 43/4 + 7

7 - 7 = 0:

2 x = 43/4 + 7

Put 43/4 + 7 over the common denominator 4. 43/4 + 7 = 43/4 + (4×7)/4:

2 x = (43/4 + (4×7)/4)

4×7 = 28:

2 x = 43/4 + 28/4

43/4 + 28/4 = (43 + 28)/4:

2 x = ((43 + 28)/4)

43 + 28 = 71:

2 x = 71/4

Divide both sides by 2:

x = (71/2)/4

4×2 = 8:

The price where the manufacture sells the maximum number of toys is $20

Step-by-step explanation:

The given equation for that represents the number of toys the manufacturer can sell is given as follows;

T = -4·p² + 160·p - 305

Where;

p = The price of the toys in dollars

At the point where the manufacture sells the maxim number of toys on the graph of the equation T = -4·p² + 160·p - 305, which is the top of the graph, the slope = 0

Therefore, at the maximum point;

The slope = 0 = dT/dp = d(-4·p² + 160·p - 305)/dp = -8·p + 160

∴ -8·p + 160 = 0

160 = 8·p

8·p = 160

p = 160/8 = 20

The price where the manufacture sells the maximum number of toys is = p = 20 dollars

The length of the base of the triangle is approximately 34.2 cm.

To find the length of the base of the isosceles triangle, we can use the cosine rule.

The cosine rule states that in a triangle with sides of lengths a, b, and c, and the angle opposite to side c is A, we have:

c² = a² + b² - 2ab × cos(A)

In this case, the congruent sides of the isosceles triangle are each 50 centimeters, so we have:

a = b = 50 cm

The vertex angle measures 40°, so A = 40°. Let's calculate the length of the base (c):

c² = 50² + 50² - 2 × 50 × 50 × cos(40°)

Now we can solve for c:

c² = 2500 + 2500 - 5000 × cos(40°)

c² = 5000 - 5000 × cos(40°)

c² = 5000 × (1 - cos(40°))

c = sqrt(5000 × (1 - cos(40°)))

Using a calculator, we find that c ≈ 34.2 cm.

Therefore, the length of the base of the triangle is approximately 34.2 cm.

So, the correct answer is: 34.2 cm
