The volume of the solid given is 1073.88 cm³.

Given is a composite solid made up of a cone and a cylinder,

We need to find the volume of the composite solid,

So, to find the same we will add both volumes of both the solids,

V(cylinder) = π × radius² × height

V(cone) = π × radius² × height / 3

So, the volume =

= 3.14 × 6² × 6.5 + 3.14 × 6² × 9/3

= 3.14(6² × 6.5 + 6² × 3)

= 3.14(234 + 108)

= 3.14 × 342

= 1073.88 cm³

Hence the volume of the solid given is 1073.88 cm³.

[tex]\alpha = 1 \quad \textsf{and} \quad \beta=2[/tex]

[tex]b=-3[/tex]

Step-by-step explanation:

If α and β are roots of x² + bx + c = 0 then the equation must be:

[tex](x -\alpha)(x - \beta) = 0[/tex]

Expanding we get:

[tex]x^2-\beta x - \alpha x + \alpha \beta = 0[/tex]

[tex]x^2-(\alpha +\beta ) x + \alpha \beta = 0[/tex]

Equating the coefficients we get:

[tex]\alpha + \beta=-b[/tex]

[tex]\alpha \cdot \beta=c[/tex]

For an equation with the roots α³ and β³, the sum of the roots can be rewritten in terms of (α + β) and (α·β) using the Sum of Cubes formula, and the Square of Binomials formula:

[tex]\begin{aligned}\alpha^3+\beta^3&=(\alpha + \beta)(\alpha^2-\alpha\beta+\beta^2)\\&=(\alpha + \beta)(\alpha^2+2\alpha\beta+\beta^2-3\alpha\beta)\\&=(\alpha + \beta)((\alpha+\beta)^2-3\alpha\beta))\end{aligned}[/tex]

Substitute in the expressions for (α + β) and αβ to find the sum of the roots α³ and β³ in terms of b and c:

[tex]\begin{aligned}\alpha^3+\beta^3&=(\alpha + \beta)((\alpha+\beta)^2-3\alpha\beta))\\&=(-b)((-b)^2-3c))\\&=-b(b^2-3c)\\&=-b^3+3bc\end{aligned}[/tex]

The product of the roots α³ and β³ in terms of c is:

[tex]\alpha \cdot \beta = c[/tex]

[tex](\alpha \cdot \beta)^3 = c^3[/tex]

[tex]\alpha^3 \cdot \beta^3=c^3[/tex]

For a quadratic equation in the form x² + bx + c = 0:

So for x² + bx + c = 0 with roots α³ and β³:

[tex]x^2-(\alpha^3 + \beta^3)x+(\alpha^3 \cdot \beta^3)=0[/tex]

[tex]x^2-\left(-b^3-3bc\right)x+c^3=0[/tex]

[tex]x^2+\left(b^3-3bc\right)x+c^3=0[/tex]

Therefore, the equation with the roots α³ and β³ is:

[tex]\boxed{x^2+\left(b^3-3bc\right)x+c^3=0}[/tex]

Substitute the given value of c = 2:

[tex]x^2+\left(b^3-3b(2)\right)x+2^3=0[/tex]

[tex]x^2+\left(b^3-6b\right)x+8=0[/tex]

If b³ - 6b + 9 = 0, then (b³ - 6b) = -9.

Substitute this into the equation:

[tex]x^2-9x+8=0[/tex]

Factor:

[tex](x-1)(x-8)=0[/tex]

Therefore, the roots of the equation with the roots α³ and β³ are 1 and 8, so the values of α and β are:

[tex]\alpha^3 =1 \implies \alpha = 1[/tex]

[tex]\beta^3=8 \implies \beta=2[/tex]

To find the real roots of b³ - 6b + 9 = 0, substitute the found values of α and β into the expression for b:

[tex]b=-(\alpha + \beta)[/tex]

[tex]b=-(1+2)[/tex]

[tex]b=-3[/tex]

Therefore, the real root of b³ - 6b + 9 = 0 is b = -3.

We can confirm this by substituting b = -3 into the equation:

[tex]\begin{aligned}(-3)^3-6(-3)+9&=-27+18+9\\&=-9+9\\&=0\end{aligned}[/tex]

The best measure of central tendency for Patrick's scores would be the median, which is 72.5.

To determine which measure of central tendency best describes Patrick's scores, let's consider the three main measures: mean, median, and mode.
1. Mean: Calculate the average by adding all scores and dividing by the number of tests.
(70 + 74 + 72 + 71 + 73 + 96) / 6 = 456 / 6 = 76
2. Median: Arrange the scores in ascending order and find the middle value.
70, 71, 72, 73, 74, 96
There are two middle values (72 and 73), so the median is their average: (72 + 73) / 2 = 72.5
3. Mode: Identify the most frequent score.
There is no mode, as all scores occur only once, except for the outlier (96).
The best measure of central tendency for Patrick's scores would be the median, which is 72.5. The median is less influenced by the outlier (96) and provides a more accurate representation of Patrick's typical performance on the science tests.

The function that provides the height of the stack of cups based on any number of cups is height(n) = 7.5 + 1.5(n-1)

Let's assume that the height of one cup is 7.5 inches.

When we add the second cup, the bottom of the second cup rests on the top of the first cup, including the 1.5" lip.

Therefore, the height of the second cup is 7.5 inches plus 1.5 inches, or 9 inches.

When we add the third cup, the bottom of the third cup rests on the top of the second cup, including the 1.5" lip.

Therefore, the height of the third cup is the height of the first two cups plus 1.5 inches, or 16.5 inches.

The function we get by continuing this pattern for any number of cups n by using the formula:

height(n) = 7.5 + 1.5(n-1)

Nina will catch up Kevin in 1 hour.

Given that Kevin has completed 90 miles in the race and Nina completed 15 miles less, Kevin continues the race at a constant rate of 25mph and Nina continues the race at a constant rate of 30mph.

So, Nina covered the distance = 90-15 = 75 miles.

So,

When will finish the race, Kevin has already covered 15 miles,

So, Nina needs to catch Kevin by covering 15 + 15 = 30 miles

To find f(8 months), we can use the formula:

f(n) = 6000 - 120n

Substituting n = 8, we get:

f(8) = 6000 - 120(8) = 5160

Therefore, f(8 months) is 5160.

To find f(22 months), we can again use the formula:

f(22) = 6000 - 120(22) = 3480

Therefore, f(22 months) is 3480.

To find f(4 years), we need to convert 4 years to months and then use the formula:

f(4 years) = f(48) = 6000 - 120(48) = 48

Therefore, f(4 years) is 48.

Becky is correct if x + y = 180° ,   indicating that BCDF is a cyclic quadrilateral. Teboho's claim would be valid if x +  y ≠ 180°.

A cyclic quadrilateral, also known as an inscribed quadrilateral in Euclidean  geometry, is a quadrilateral with all   of its vertices on a single circle.

To determine the size of angle C in terms of x and y, we can use the fact that tangent BC touches the circle ABDE at B.

This means that angle C is equal to the angle formed between the chord AD and the tangent BC at point B.

4.1.1

Since AB || EC, we can use the alternate interior angles theorem to determine the relationship between angles C and A₁.

Angle C is equal to angle A₁ because they are corresponding angles.

Therefore, the size of angle C is y.

4.1.2   - To determine if BCDF is a cyclic quadrilateral

 In order to check if BCDF is cyclic, we need to determine if the opposite angles in the quadrilateral add up to 180° .

Let's consider angle BCD and angle BFD:

Angle BCD is equal to angle B₁ (given) and is represented by x.

Angle BFD is equal to angle A₁ (since BCDF is a cyclic quadrilateral) and is represented by y.

If x + y = 180 degrees, then BCDF is a cyclic quadrilateral.

Using the combination formula, we calculate that there are 133,784,560 different 7-card hands that can be chosen from a standard 52-card deck.

A standard 52-card deck has 52 unique cards, and to find the number of different 7-card hands that can be chosen, we use the combination formula, which is C(52,7). This formula represents the number of ways to choose 7 cards out of a total of 52 cards, where order does not matter.

The formula for C(52,7) is derived by using factorials. For example, 52! represents 52 x 51 x 50 x 49 x 48 x 47 x 46 x ... x 2 x 1, which is the total number of ways to arrange all 52 cards.

Step-by-step explanation:

We know that the original recipe is for 6 people, and it requires 800g of pineapple, 4 egg whites, and 1/2 lemon.

If Dan uses 2 1/2 lemons instead of 1/2 lemon, that means he's using 5 times as much lemon juice. Therefore, he's likely making 5 times the original recipe.

So, for Dan's pineapple sorbet, he would need:

800g x 5 = 4000g (or 4kg) of pineapple

4 x 5 = 20 egg whites

1/2 lemon x 2.5 = 1 1/4 lemons (but since we can't really use a quarter of a lemon, we'll just say he needs 1.5 lemons)

Therefore, Dan is making pineapple sorbet for 6 x 5 = 30 people.

When we have two large independent samples from two populations, the difference in the two sample means will follow an approximate normal distribution.

This is due to the central limit theorem, which states that when we have a large enough sample size (typically, greater than 30), the distribution of the sample means will be normal regardless of the underlying distribution of the populations. As the two samples are independent, the difference in means will also be independent. Therefore, we can use the normal distribution to estimate the probability of observing a certain difference in means. It is important to note that this approximation may not hold for small sample sizes, and the underlying distributions of the populations can also impact the shape of the distribution. We can say that the normal distribution approximation is widely used in statistics and hypothesis testing, making it an essential concept for understanding and interpreting data.

Therefore, in a 2x2 table, the pattern of cell frequencies that would indicate independence is d. All cell frequencies are exactly the same.

In a 2x2 contingency table, the expected cell frequencies under the null hypothesis of independence are equal for all cells. If the observed cell frequencies in the table are approximately equal to the expected cell frequencies, then we can conclude that there is no significant association between the two variables being studied. In other words, the pattern of observed cell frequencies is consistent with the null hypothesis of independence. Therefore, if all cell frequencies are exactly the same, it suggests that the variables are independent, as each cell has an equal chance of being filled by any observation regardless of the value of the other variable.
