The requried to calculate an F ratio, we need to perform an analysis of variance (ANOVA) test.

To calculate an F ratio, we need to perform an analysis of variance (ANOVA) test. The F ratio is the ratio of two variances, and it is calculated by dividing the mean square of the between-group variability by the mean square of the within-group variability.

The formula for the F ratio is:

F = MSB / MSW

Where MSB is the mean square of the between-group variability and MSW is the mean square of the within-group variability.

The F ratio is used to test the null hypothesis that the means of the groups are equal. If the F ratio is greater than the critical value for a given level of significance (based on the degrees of freedom), we reject the null hypothesis and conclude that at least one group's mean is different from the others.

Answer:

Since \(s=\frac{3}{4}ft\),

27 ÷ s² = 27 ÷ \((\frac{3}{4})^{2}\)

            = 27 ÷ \(\frac{9}{16}\)

            = \(\frac{27}{1}\) × \(\frac{16}{9}\)

            = 48

∴ Mr Grant would need to buy 48 of such square tiles.

Step-by-step explanation:

what that simply means is that the area he needs the files for is 27 ft².

as the tiles are squares, each one has an individual area of s² = 3/4 × 3/4 = 9/16 ft²

how many tiles do we need ?

as b many as how often the area of one tile fits into the total area :

27 ÷ s² = 27 / 9/16 = 27/1 / 9/16 = 27/1 × 16/9 =

= 3/1 × 16/1 = 3×16 = 48

he has to buy 48 tiles.

Answer:

Step-by-step explanation:

"A bill" = "1 bill"

Possibile bills = $1, $5, $10, $20, $50, $100

4 × 1.65 = 6.6

$6.60 is more than $5, but less than $10

Since the student is only using a single bill, it must be the $10 bill

10 - 6.6 = 3.4

If it is impossible for events A and B to occur simultaneously, the events are said to be mutually exclusive. For such events, P(A or B) is equal to the sum of the individual probabilities of events A and B.

In other words, if A and B are mutually exclusive events, the probability of A or B occurring is equal to the sum of the probabilities of A and B individually.

Mathematically, P(A or B) = P(A) + P(B).

This holds true because when two events are mutually exclusive, the occurrence of one event excludes the possibility of the other event happening at the same time. Therefore, there is no overlap in the outcomes, and we can simply add their probabilities to calculate the probability of either event occurring.

Rewriting 48 - 28 using the Distributive Property and the GCF of the numbers, you get 4(5) = 20.

To rewrite 48 - 28 using the Distributive Property and the GCF of the numbers, follow these steps:
Step:1. First, find the GCF (Greatest Common Factor) of 48 and 28.
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The factors of 28 are: 1, 2, 4, 7, 14, 28
The GCF of 48 and 28 is 4.
Step:2. Now, use the Distributive Property to factor out the GCF from both numbers.
48 - 28 = 4(12) - 4(7)
Step:3. Distribute the GCF to both terms in parentheses.
48 - 28 = 4(12 - 7)
Step:4. Finally, simplify the expression inside the parentheses.
48 - 28 = 4(5)
So, rewriting 48 - 28 using the Distributive Property and the GCF of the numbers, you get 4(5) = 20.

Step-by-step explanation:

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

you have a 6 sided die that is numbered 1, 2, 3, 4, 5, and 6.

you roll it once, so the probability that you will roll a five is 1/6

this is because you only want one specific number so that goes on the numerator of the fraction.

then, you have to multiply how many sides you have on the die to the number of rolls. in this case we have one roll and six sides. so the six goes on the denomerator side of the fraction

Explanation:

The boundary line is y = 2x-2. This line goes through (0,-2) and (2,2). Use the slope formula to find the slope to be m = 2, and use the y intercept b = -2 to help form the equation.

Since the boundary line is solid, we will have "or equal to" as part of the inequality sign. This indicates points on the boundary are part of the solution set. Furthermore, we will have a greater than sign because the shaded region is above the boundary. Therefore, we change the equal sign to a "greater than or equal to" sign, going from y = 2x-2 to \(y \ge 2x-2\)

If we simply did \(y > 2x-2\) without the "or equal to" portion, then the boundary line would be dotted or dashed to tell the reader "points on the boundary are not part of the solution set".

Answer:

Step-by-step explanation:

To find the x- and y-intercepts of the graph of the equation 6x + 5y = 366, we set one of the variables to zero and solve for the other variable.

x-intercept: To find the x-intercept, we set y to zero and solve for x.

6x + 5(0) = 366

6x = 366

x = 366/6

x = 61

Therefore, the x-intercept is (61, 0).

y-intercept: To find the y-intercept, we set x to zero and solve for y.

6(0) + 5y = 366

5y = 366

y = 366/5

Therefore, the y-intercept is (0, 366/5) or (0, 73.2) as a decimal.

In summary, the x-intercept is (61, 0) and the y-intercept is (0, 73.2) or (0, 366/5) in fractional form.

Step-by-step explanation:

To find the x-intercept, we set y to zero and solve for x.

6x + 5y = 366

When y = 0:

6x + 5(0) = 366

6x = 366

x = 366/6

x = 61

Therefore, the x-intercept is 61.

To find the y-intercept, we set x to zero and solve for y.

6x + 5y = 366

When x = 0:

6(0) + 5y = 366

5y = 366

y = 366/5

Therefore, the y-intercept is 366/5, which cannot be simplified further.

In simplest form, the x-intercept is 61 and the y-intercept is 366/5.

Thus, the volume of solid generated by revolving this region about the y-axis is given as:  54π/7. The correct option is c.

To sketch the region, we first plot the curves on the coordinate plane.

The curve x=3y^3 is a parabola that opens to the right and passes through the origin. The curve x=3 is a vertical line that intersects the parabola at y=∛(1/3).

The curve y=0 is just the x-axis.

Now, to find the volume of the solid generated by revolving this region about the y-axis, we use the method of cylindrical shells.

We integrate from y=0 to y=∛(1/3) because those are the limits of integration for the region we are revolving.

The radius of each cylindrical shell is just the value of x at that y-coordinate, which is x=3y^3. The height of each cylindrical shell is the length of the curve, which is just 3 (the length of the vertical line).

Thus, the volume is given by:

V = ∫0^(∛(1/3)) 2π(3y^3)(3) dy
V = 54π/7

Therefore, the correct option is (c) 54π/7.

Step-by-step explanation:

If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :).

3. The measure of angle S in the given pentagon is 155.33 degrees. 4. The value of x is 9. 5. The value of x is 40 degrees. 6. The value of angle C is 33 degrees. 7. The polygon has 30 sides.

A polygon having 5 sides and 5 angles is called a pentagon. Two terms, Penta and Gonia, both of which denote five angles, combine to form the word "pentagon." End to end, the sides of a pentagon come together to form a shape. Every side of a regular pentagon has the same length, and its five angles are all the same size. A pentagon is said to as irregular if its side length and angle measurement are not equal.

The sum of angles of a pentagon is equal to 540 degrees.

Thus,

5x + 2 + 10x - 3 + 8x - 19 + 13x - 31 + 7x - 11 = 540

42x - 62 = 540

42x = 602

x = 14.33

The angle of s is:

13(x) - 31 = 13(14.33) - 31 = 155.33

Hence, the measure of angle S in the given pentagon is 155.33 degrees.

4. In a regular hexagon, each angle is equal, and the sum of all the angles is equal to 720 degrees.

6A = 720

A = 120

11x + 21 = 120

x = 9

5. The angle of a nonagon is 140 degrees.

Now, 140 + x = 180

x = 80 degrees.

6. For the given triangle we have:

exterior angle of C = D + E

Substituting the value of D and E as:

7x - 2 = 180 - 9x + 31 + 180 - 4x + 33

7x - 2 = 360 - 13x + 64

20x = 426

x = 21.3

Angle C = 180- (7(21.3) - 2) =  33 degrees.

7. single angle = (n-2) x 180 / n

168n = (n - 2) 180

168n = 180n - 360

360 = 12n

n = 30

The polygon has 30 sides.
