Answer:

The confidence interval is \(0.15 < p < 0.19\)

Step-by-step explanation:

From the question we are told that

  The sample proportion is  \(\^ p = 0.17\)

  The margin of error is \(E = 0.02\)

Generally the confidence interval  for the proportion of oil paintings that contained ultramarine blue is mathematically represented as

       \(\^ p - E < p < \^ p + E\)

=>   \(0.17 - 0.02 < p < 0.17 + 0.02\)

=>   \(0.15 < p < 0.19\)

The sheet decreased by 1.5 meters and is now at 2.5 meters.

An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario.

In this case, s=−0.25t + 4 represents the thickness of the ice over t weeks. To find the thickness at 6 weeks, substitute t=6.

s = -0.25(6)+4

s = 2.5 meters

It started at t= 0 at 4 meters. So it decreased by (4 - 2.5) = 1.5 meters.

The start of spring has 4 meters because when t= 0, s= -0.25(0)+4 = 4

Given statement solution is :- The present value of R13,000 per year invested for 8 years at 10% compound interest is approximately R69,776.60.

To calculate the present value of an investment with compound interest, we can use the formula for the present value of an annuity:

PV = A *\((1 - (1 + r)^(-n)) / r\)

Where:

PV = Present value

A = Annual payment or cash flow

r = Interest rate per period

n = Number of periods

In this case, the annual payment (A) is R13,000, the interest rate (r) is 10% per year, and the investment is made for 8 years (n).

Using the formula and substituting the given values, we can calculate the present value:

PV = \(13000 * (1 - (1 + 0.10)^(-8)) / 0.10\)

Calculating this expression:

PV = \(13000 * (1 - 1.10^(-8)) / 0.10\)

= 13000 * (1 - 0.46318) / 0.10

= 13000 * 0.53682 / 0.10

= 6977.66 / 0.10

= 69776.6

Therefore, the present value of R13,000 per year invested for 8 years at 10% compound interest is approximately R69,776.60.

Answer: Half of them are even and half of them are odd.

Step-by-step explanation:

The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.

The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.

Therefore, out of the given numbers, half of them are even and half of them are odd.

Step-by-step explanation:

1 foot = 12 inches

5 feet = ?

5*12 = 60

\(1\cdot \text{foot} = 12\cdot \text{inches} \implies 5 \cdot\text{foot} =5\cdot 12 \cdot\text{inches} \implies 5 \cdot\text{foot} =60 \cdot\text{inches}\)

The final result of the integral is:

∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,

where Li(x) is the logarithmic integral function and C is the constant of integration.

We have,

To solve the integral ∫ (log(1 + x²) / (x + 1)²) dx, we can use the method of substitution.

Let's substitute u = x + 1, which implies du = dx. Making this substitution, the integral becomes:

∫ (log(1 + (u-1)²) / u²) du.

Expanding the numerator, we have:

∫ (log(1 + u² - 2u + 1) / u²) du

= ∫ (log(u² - 2u + 2) / u²) du.

Now, let's split the logarithm using the properties of logarithms:

∫ (log(u² - 2u + 2) - log(u²)) / u² du

= ∫ (log(u² - 2u + 2) / u²) du - ∫ (log(u²) / u²) du.

We can simplify the second integral:

∫ (log(u²) / u²) du = ∫ (2 log(u) / u²) du.

Using the power rule for integration, we can integrate both terms:

∫ (log(u² - 2u + 2) / u²) du = log(u² - 2u + 2) / u - 2 ∫ (log(u) / u³) du.

Now, let's focus on the second integral:

∫ (log(u) / u³) du.

This integral does not have a simple closed-form solution in terms of elementary functions.

It can be expressed in terms of a special function called the logarithmic integral, denoted as Li(x).

Therefore,

The final result of the integral is:

∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,

where Li(x) is the logarithmic integral function and C is the constant of integration.

Here, the specific subset is adults who prefer watermelon, which is 111. The total number of data points is the sum of all children and adults, regardless of fruit preference, which is 445.

So, to find the joint relative frequency of being an adult who prefers watermelon, you would divide 111 by 445.

Hence, the correct answer is:

C. Divide 111 by 445.

By proving that ΔEAB and ΔFDC have congruent corresponding angles and proportional corresponding sides, we can conclude that ΔEAB ≅ ΔFDC.

Given:

- Triangle ΔAEB and ΔDFC

- Line ABCD is straight (implies AC and BD are collinear)

- AE is parallel to DF

- EB is parallel to FC

- AC = DB

To prove: ΔEAB ≅ ΔFDC

Recall that:

AE || DF

EB || FC

AC = DB

AE || DF, EB || FC (Parallel lines with transversal line AB)

Corresponding angles are congruent:

  ∠AEB = ∠DFC (Corresponding angles)

  ∠EAB = ∠FDC (Corresponding angles)

Corresponding sides are proportional:

  AE/DF = EB/FC (Corresponding sides)

  AC/DB = BC/DC (Corresponding sides)

  AC = DB

  BC = DC (Equal ratios)

ΔEAB ≅ ΔFDC (By angle-side-angle (ASA) congruence)

∠EAB = ∠FDC

∠AEB = ∠DFC

AC = DB, BC = DC

Therefore, by proving that ΔEAB and ΔFDC have congruent corresponding angles and proportional corresponding sides, we can conclude that ΔEAB ≅ ΔFDC.

Answer:

Europe 1.86 VS 0.79 US

Step-by-step explanation:

All you have to do is take US gass prices and simply divide it by four then compare.

The price compared with the cost of gasoline in the United States will be $7.44 per gallon.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

In most countries, gasoline is measured in liters. The volume of one liter is approximately one quart. There are four quarts in one gallon.

Then the conversion of liter to gallons will be

1 liter = 1 quart

1 gallon = 4 quarts

1 gallon = 4 liters

In Europe, gasoline costs $1.86/liter.

Then the price compared with the cost of gasoline in the United States will be

⇒ $1.86 / liter

⇒ $1.86 / (1/4) gallon

⇒ $1.86 x 4

⇒ $7.44 per gallon

The price compared with the cost of gasoline in the United States will be $7.44 per gallon.

Answer:

y = 1.78x + 4.28

Step-by-step explanation:

first isolate y

1.8y = 3.2x + 7.7

now that y is isolated, we can divide out the 1.8

y = 1.78x + 4.28

Answer:

\(y=\dfrac{16}{9}x + \dfrac{77}{18}\)

Step-by-step explanation:

To solve for y in this equation, we need to isolate the y term on one side, then multiply by the reciprocal of its coefficient. Remember that any number multiplied by its reciprocal is 1.

3.2x - 1.8y + 7.7 = 0

↓ add 1.8y to both sides

3.2x + 7.7 = 1.8y

↓ represent the decimals as fractions

\(\dfrac{16}{5}x + \dfrac{77}{10} = \dfrac{9}{5}y\)

↓ multiply by the reciprocal of y's coefficient: \(\frac{5}{9}\)

\(\dfrac{5}{9} \cdot \left(\dfrac{16}{5}x + \dfrac{77}{10}\right) = \left(\dfrac{9}{5}y\right) \cdot \dfrac{5}{9}\)

↓ simplify

\(\boxed{\dfrac{16}{9}x + \dfrac{77}{18} = y}\)

Step-by-step explanation:

we need to find the LCM, the least (or lowest) common multiple, of 3 and 4.

that means the smallest number that can be divided by 3 and by 4 without remainder.

and that is simply in our case 3×4 = 12.

so, every 12th day they will walk to the lake "together" (on the same day).

FYI - formality the LCM is found e.g. by prime factorization.

starting with the smallest prime number (2) both numbers are divided by the prime number, if there is no remainder. the quotient is then again divided by the prime number. if there is a remainder, then the next higher prime number is taken for the division.

this goes on until we get a quotient of 1.

the LCM is then the product of the longest streaks of the products of the same prime numbers.

example LCM of 56 and 50

56 ÷ 2 = 28 (0 remainder)

28 ÷ 2 = 14 (0 remainder)

14 ÷ 2 = 7 (0 remainder)

7 ÷ 2 has a remainder, so the next prime number (3)

7 ÷ 3 has a remainder, so the next prime number (5)

7 ÷ 5 has a remainder, so the next prime number (7)

7 ÷ 7 = 1 finished

50 ÷ 2 = 25 (0 remainder)

25 ÷ 2 has a remainder, so the next prime number (3)

25 ÷ 3 has a remainder, so the next prime number (5)

25 ÷ 5 = 5 (0 remainder)

5 ÷ 5 = 1 finished

the longest streaks of prime number products :

2×2×2 = 8

5×5 = 25

7 = 7

the LCM = 8×25×7 = 1400

please consider, this is NOT 56×50 = 2800.

the LCM is not automatically just the product of both numbers. this product is a common multiple, true, but not always the smallest.

in our case here with 3 and 4

3 ÷ 2 has a remainder, so the next prime number (3)

3 ÷ 3 = 1 finished

4 ÷ 2 = 2 (0 remainder)

2 ÷ 2 = 1 finished

the longest prime number product streaks :

2×2 = 4

3 = 3

the LCM = 4×3 = 12

so, in this case the LCM is the direct product of both numbers.

The probability is closer to one than zero.

Probability theory is used to analyze and predict the likelihood of events happening in various fields such as statistics, gambling, physics, finance, and more. It allows us to make informed decisions based on the likelihood of different outcomes. In probability theory, the total number of possible outcomes is important to determine the probability of a single event occurring. By comparing the favorable outcomes to the total outcomes, we can calculate the probability of an event happening.

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it. Probability can range from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event. Probability for Class 10 is an important topic for the students which explains all the basic concepts of this topic. The probability of all the events in a sample space adds up to 1.For example, when we toss a coin, either we get Head OR Tail, only two possible outcomes are possible (H, T). But when two coins are tossed then there will be four possible outcomes,  i.e {(H, H), (H, T), (T, H), (T, T)}.
