Answers

Answer 1

Answer:

Step-by-step explanation:

Let the consecutive even integers be 2n and 2n+2.

lesser integer = 2n

Greater integer = 2n+2

If twice the lesser of two integers is 4 less than two times the greater integer, this is expressed mathematically as;

2(less integer) = 2(greater integer) - 4

Substituting the given integers;

2(2n) = 2(2n+2)-4

2(2n) = 2[(2n+2)-2]

2n = 2n+2-2

2n = 2n

2 = 2

This two values cancels out and become 0 = 0. This equality shows that it is an identity pair and it is true for all even integers.

The measures of the angles are

TLN = 51 degrees, NLM = 129 degrees and MZQ =  129 degreesJZQ = TLN = 99 degreesLMO= ZMR = 34 degrees and  LMR = y = 166 degrees

How to determine the measures of the angles?

1. Angle TLN, MZQ and NLM

The angles TLN and NLM are supplementary angles

So, we have

TLN + NLM = 180

This gives

3x - 18 + y = 180

Also, we have

TLN + MZQ = 180

So, we have

3x - 18 + 5x + 14 = 180

Evaluate the like terms

8x -4 = 180

This gives

8x = 184

Divide

x = 23

Substitute x = 23 in 3x - 18 + y = 180

3 x 23 - 18 + y = 180

Evaluate

51 + y = 180

So, we have

y = 129

The above computations imply that:

TLN = 3 x 23- 18 = 51 degrees

NLM = y = 129 degrees

MZQ = 5 x 23 + 14 = 129 degrees

2. Angle JZQ and TLN

The above means that

JZQ = TLN

So, we have

9x + 9 = 8x + 19

Evaluate

x = 10

So, we have

JZQ = TLN = 9 * 10 + 9

JZQ = TLN = 99 degrees

3. Angle ZMR, LMO and LMR

The angles ZMR and LMO are congruent angles

So, we have

ZMR = LMO

This gives

x + 14 = 2x - 6

Evaluate

x = 20

Also, we have

LMR + LMO = 180

So, we have

y + 2x - 6 = 180

y + 2 x 10 - 6 = 180

y + 14 = 180

So, we have

y = 166

The above computations imply that:

LMO= ZMR = 20 + 14 = 34 degrees

LMR = y = 166 degrees

The lateral area of the smaller cylinder is 25pi and the lateral area of the larger cylinder is 64pi. If the volume of the smaller cylinder is 150pi, what is the volume of the larger cylinder?

The lateral area of the smaller cylinder is 25pi and the lateral area of the larger cylinder is 64pi.

Answers

The volume of the larger cylinder is (25/8)πR³.

What is volume?

Volume is a measure of the amount of space occupied by a three-dimensional object. It is typically measured in units of cubic meters, cubic centimeters, cubic feet.

According to question:

Let's denote the radius and height of the smaller cylinder as r and h, respectively, and the radius and height of the larger cylinder as R and H, respectively.

We know that the lateral area of a cylinder is given by the formula:

Lateral area = 2πrh

Using this formula for the smaller and larger cylinders, we get:

25π = 2πrh

64π = 2πRH

Dividing both sides of the first equation by 2π, we get:

rh = 25/2π

We also know that the following formula determines a cylinder's volume:

Volume = πr²h

Using this formula for the smaller cylinder, we get:

150π = πr²h

Substituting rh = 25/2π from above, we get:

150π = πr²(25/2π)

r² = 12

Taking the square root of both sides, we get:

r = √12 = 2√3

Substituting this value into rh = 25/2π, we get:

h = 25/(2πr) = 25/(4π√3)

Now, we can use the ratio of the lateral areas to find the ratio of the heights:

25π/64π = (2πrh)/(2πRH)

25/64 = rh/RH

25/64 = (2√3)(25)/(4πR)(H)

H = 2hR/r

Finally, we can use the formula for the volume of the larger cylinder to find its volume:

Volume = πR²H

Volume = πR²(2hR/r)

Volume = 2πR³h/r

Substituting the values we found for r, h, and H, we get:

Volume = 2π(R³)(25/(4π√3))/(2√3)

Volume = (25/8)πR³

Therefore, the volume of the larger cylinder is (25/8)πR³.

Aaron ate ½ as much pizza as David. If Aaron ate ¼ of a pie, what fraction of the pie did David eat? Write and solve an equation.

Answers

Given that Aaron ate half as much pizza as David and Aaron ate 1/4 of a pie, we can determine the fraction of the pie David ate by setting up an equation and solving for it.

Let's assume that David ate x amount of pizza, which represents the fraction of the pie he consumed. Since Aaron ate half as much pizza as David, we can express Aaron's portion as (1/2)x. We are also given that Aaron ate 1/4 of a pie, so we can set up the equation:

(1/2)x = 1/4

To solve for x, we can multiply both sides of the equation by 2 to eliminate the fraction:

2 * (1/2)x = 2 * (1/4)

x = 1/2

Therefore, David ate 1/2 of the pie. This means that Aaron ate half as much pizza as David, while David consumed the remaining half of the pie.

The equation of the polynomial is P(x) = 0.16875x² - 0.3375x - 13.5

How to determine the equation of the polynomial

From the question, we have the following parameters that can be used in our computation:

The graph

On the graph, we have the following readings:

A root of multiplicity 1 at x = -8A root of multiplicity 1 at x = 10y-intercept = -13.5

A polynomial is represented as

P(x) = a * (x - zero)^multiplicity

Using the above as a guide, we have the following:

P(x) = a * (x + 8)(x - 10)

The y-intercept is -13.5

So, we have

a * (0 + 8)(0 - 10) = -13.5

This gives

a = 0.16875

Recall that

P(x) = a * (x + 8)(x - 10)

So, we have

P(x) = 0.16875(x + 8)(x - 10)

Expand

P(x) = 0.16875(x² + 8x - 10x - 80)

P(x) = 0.16875(x² - 2x - 80)

Remove bracket

P(x) = 0.16875x² - 0.3375x - 13.5

Hence, the expression is P(x) = 0.16875x² - 0.3375x - 13.5

Answers

 The sample we collect plays a cruciThe sample we collect can significantly affect our understanding of a population,

especially when it comes to making generalizations or drawing conclusions about the entire population based on the sample data. The key aspect in this regard is whether the sample is representative of the population.

A representative sample is one that accurately reflects the characteristics, diversity, and distribution of the population from which it is drawn. When our sample is representative, we can have greater confidence in generalizing the findings from the sample to the larger population. However, if our sample is not representative, our understanding of the population may be biased or limited.

In the provided example, the given data represents different age groups and their reported time spent with friends per day. If we were to collect a sample from this population, it would be crucial to ensure that the sample includes individuals from each age group in proportion to their representation in the population. This would help ensure that our sample accurately reflects the age distribution of the population.

If our sample is not representative, it may lead to inaccurate conclusions. For instance, if we only surveyed individuals from the age group 55-64 and ignored the other age groups, our understanding of the population's time spent with friends would be limited to that specific age group. We wouldn't be able to generalize our findings to the entire population because we would have missed important variations in behavior across other age groups.

To improve the representativeness of our sample, we could use random sampling techniques, such as simple random sampling or stratified sampling, to ensure that individuals from all age groups are included in the sample. By doing so, we can enhance our understanding of the population as a whole and make more accurate inferences.

In conclusion, the sample we collect plays a crucial role in shaping our understanding of a population. A representative sample enables us to make valid generalizations and draw reliable conclusions about the entire population. It ensures that the characteristics and diversity of the population are properly reflected in the sample, allowing for more accurate insights and informed decision-making.al role in shaping our understanding of a population

Lindsey is working really hard to improve her grade. on her first quiz she scored 67 point, on her second she scored 71, and on her third she scored 75. her scores continue to increase at the same rate. write a recursive and explicit formula for this geometric sequence.

Answers

The recursive formula for Lindsey's scores is aₙ = aₙ₋₁ \(\times\) r, and the explicit formula is aₙ \(= 67 \times r^{(n-1).\)

To find the recursive and explicit formulas for the given geometric sequence, let's analyze the pattern of Lindsey's scores.

From the given information, we can observe that Lindsey's scores are increasing at the same rate.

This suggests that the scores form a geometric sequence, where each term is obtained by multiplying the previous term by a common ratio.

Let's denote the first term as a₁ = 67 and the common ratio as r.

Recursive Formula:

In a geometric sequence, the recursive formula is used to find each term based on the previous term. In this case, we can write the recursive formula as:

aₙ = aₙ₋₁ \(\times\) r

For Lindsey's scores, the recursive formula would be:

aₙ = aₙ₋₁ \(\times\) r

Explicit Formula:

The explicit formula is used to directly calculate any term of a geometric sequence without the need to calculate the previous terms.

The explicit formula for a geometric sequence is:

aₙ = a₁ \(\times r^{(n-1)\)

For Lindsey's scores, the explicit formula would be:

aₙ \(= 67 \times r^{(n-1)\)

In both formulas, 'aₙ' represents the nth term of the sequence, 'aₙ₋₁' represents the previous term, 'a₁' represents the first term, 'r' represents the common ratio, and 'n' represents the term number.

Dan is doing a study of start-up costs for small businesses. A random sample of 15 specialty clothing stores had sample mean start-up costs $92,000 with sample standard deviation $24,000. An independent random sample of 12 coffee houses had mean start-up costs $74,000 with sample standard deviation $18,000. Required:

Test to see if the data supports the hypothesis that the start-up costs of the two types of businesses are different. Use a 1% significance level.

Answers

The data supports the hypothesis that the start-up costs of the two types of businesses, specialty clothing stores and coffee houses, are significantly different at a 1% significance level.

The null hypothesis (H₀): The start-up costs of specialty clothing stores and coffee houses are equal.

The alternative hypothesis (H₁): The start-up costs of specialty clothing stores and coffee houses are different.

The significance level (α) is given as 1% or 0.01.

The test statistic for a two-sample t-test is given by:

t = (x₁ - x₂) / √[(s₁²/n₁) + (s₂²/n₂)]

Plugging in the given values:

x₁ = $92,000, x₂ = $74,000, s₁ = $24,000, s₂ = $18,000, n₁ = 15 and n₂ = 12

t = (92,000 - 74,000) / √[(24,000²/15) + (18,000²/12)]

Since the significance level is 1% (0.01), we need to find the critical value for a two-tailed test with a degree of freedom equal to (n₁ + n₂ - 2).

We can use a t-table or statistical software to find this value.

For a significance level of 0.01 and degrees of freedom (15 + 12 - 2 = 25), the critical value is approximately ±2.796.

If the absolute value of the calculated t-statistic is greater than the critical value from Step 4, we reject the null hypothesis.

Otherwise, we fail to reject the null hypothesis.

Let's calculate the test statistic:

t = (92,000 - 74,000) / √[(24,000²/15) + (18,000²/12)]

= 18,000 / √[(3,840,000/15) + (3,240,000/12)]

= 24.82

Since the absolute value of the calculated t-statistic (|24.82|) is greater than the critical value (2.796) at the 1% significance level, we reject the null hypothesis.
