6 chickens and 14 pigs in the farm.

Let the number of chickens in the farm = x

Let the number of pigs in the farm = y

Number of legs of chickens = 2*x (since chickens have 2 legs)

Number of legs of pigs = 4*y (since pigs have 4 legs)

We are given that there are a total of 30 animals (pigs + chickens)

so, number of chickens + number of pigs = 30

x + y = 30

We are given that there is a total of 68 legs in the farm

so, legs of chickens + legs of pigs = 68

2x + 4y = 68

Solving for number of chickens and pigs:

from the question, we have deduced that:

x + y = 30

2x + 4y = 68

taking the value of x from the first equation and using it in the second equation:

x = 30 - y

2(30-y) + 4y = 68

60- 2y + 4y = 68

40 + 2y = 68

2y = 68-40

2y = 28

y = 14

Using this value of y in the first equation:

x + y  = 30

x + (14) = 20

x = 20-14

x = 6

Therefore, there are 6 chickens and 14 pigs in the farm

The proportion of the area under the curve that lies to the right of t = 2.015 in a t-distribution with 5 degrees of freedom can be calculated using the t-distribution function in a statistical software package such as R.

The answer is approximately 0.9522. This means that 95.22% of the area under the curve lies to the right of t = 2.015. This indicates that the probability of observing a value of t greater than 2.015 is quite high.

This is because the t-distribution with 5 degrees of freedom has a larger spread than the normal distribution, which means that the probability of observing values further from the mean is greater.

The confidence interval .222 < p < .888 can be expressed as p - e, where p = 0.555 and e = 0.333.

In a confidence interval, the point estimate represents the best estimate of the true population parameter, and the margin of error represents the range of uncertainty around the point estimate.

To express the given confidence interval in the form p - e, we need to find the point estimate and the margin of error.

The point estimate is the midpoint of the interval, which is the average of the upper and lower bounds. In this case, the point estimate is (0.222 + 0.888) / 2 = 0.555.

To find the margin of error, we need to consider the distance between the point estimate and each bound of the interval.

Since the interval is symmetrical, the margin of error is half of the range.

Therefore, the margin of error is (0.888 - 0.222) / 2 = 0.333.

Now we can express the confidence interval .222 < p < .888 as the point estimate minus the margin of error, which is 0.555 - 0.333 = 0.222.

Therefore, the confidence interval .222 < p < .888 can be expressed as p - e, where p = 0.555 and e = 0.333.

Answer:

\(A)5\frac{1}{2}\)

Step-by-step explanation:

To multiply a number and a mixed number, first convert the improper fraction to a mixed number. This can be done by multiplying the "number" part of the mixed number by the denominator (number underneath the fraction bar) and then adding the result to the numerator. After doing so, one can either multiply the improper fraction by the number, and then simplify the result, or one can cross simplify the number and the denominator, then multiply by the numerator.

\(4 * 1\frac{3}{8}\\\\4 * \frac{11}{8}\\\\=\frac{44}{8}\\\\= \frac{11}{2}\)

Now one must convert this improper fraction to a mixed number. One can do this by diving the numerator by the denominator, writing the result as the "number" part of the mixed number, and then writing the remainder as the numerator of the fraction.

Step-by-step explanation:

The present age of Earl is 12 years, Robin is 24 years and Adam is 4 years old.

Let us consider the present age of Earl to be x years.

According to the given question, the present age of Robin is twice that of Earl = 2x

And since it is given that Adam is 8 years younger than Earl, then his age

= x - 8

After 6 years, the age of Earl will be x + 6

Robin's age  will be = 2x + 6

Adam's age will be = x - 8 + 6 = x - 2

According to the given question, Robin's age will be thrice the age of Adam.

Hence, 2x + 6 = 3 (x - 2)

⇒ 2x + 6 = 3x - 6     ⇒ 6 + 6 = 3x - 2x     ⇒ 12 = x

Thus, the present age of Earl is 12 years,

Robin's age = 2x = 2 x 12 = 24 years

Adam's age = x - 8 = 12 - 8 = 4 years

Step-by-step explanation:

Using the distributive property, we know that we can distribute to polynomial within parenthesis. So, following this, we can multiple 2*5a and 2*3. This gives us the expression, 10a+6. Showing that these two expressions are equivalent.

Additionally, the expression 2(5a+3) is an example of factoring. The GCF, 2, was factored out of the original expression 10a+6. Since 2(5a+3) is a factored form of 10a+6, they must be equivalent.

Answer:

After 5 months, she will save the same amount using either option.

She would have saved $450 with either option.

Step-by-step explanation:

Set up expressions to represent the amount of money saved for each saving option, where x is the number of months

The first one can be represented by 30x + 300

The second one can be represented by 50x + 200

Set these equal to each other and solve for x:

30x + 300 = 50x + 200

300 = 20x + 200

100 = 20x

5 = x

So, after 5 months, Tina will save the same amount of money with both options.

To find how much she will save, plug in 5 as x into either expression:

30x + 300

30(5) + 300

150 + 300

= 450

So, she would have saved $450 with either option.

Step-by-step explanation:

The probability of winning $100 by matching exactly three of the first five and the sixth numbers is 0.0018. The probability of winning $100 by matching four of the first five numbers but not the sixth number is 0.0003.

To calculate the probability of winning $100 by matching exactly three of the first five and the sixth numbers, we first need to determine the total number of possible combinations for the first five numbers. Since each of the five numbers can be any number between 1 and 69, there are 69 choose 5 (written as 69C5) possible combinations, which is equal to 11,238,513. Out of these 11,238,513 possible combinations, we need to choose three numbers that will match the drawn numbers and two numbers that will not match. The probability of matching three numbers is calculated as 5C3/69C5, which is equal to 0.0018. The probability of not matching the remaining two numbers is 64C2/64C2, which is equal to 1.

Therefore, the probability of winning $100 by matching exactly three of the first five and the sixth numbers is 0.0018 x 1, which is equal to 0.0018. To calculate the probability of winning $100 by matching four of the first five numbers but not the sixth number, we need to determine the total number of possible combinations for four of the first five numbers. Since each of the four numbers can be any number between 1 and 69, there are 69 choose 4 (written as 69C4) possible combinations, which is equal to 4,782,487.

Out of these 4,782,487 possible combinations, we need to choose four numbers that will match with the drawn numbers and one number that will not match. The probability of matching four numbers is calculated as 5C4/69C4, which is equal to 0.0003. The probability of not matching the remaining number is 64/64, which is equal to 1. Therefore, the probability of winning $100 by matching four of the first five numbers but not the sixth number is 0.0003 x 1, which is equal to 0.0003.

Step-by-step explanation:

The crude oil is likely to be paraffinic. Paraffinic crude oils are characterized by having a high API°, low Watson characterization factor, and low refractive index. They also tend to have a high surface tension.

Specific gravity at 60 °F: 0.88

API° at 60 °F: 28

Watson characterization factor: 1.014

Refractive index: 1.44

Surface tension: 20 dyne/cm

Paraffinic, naphthenic, or aromatic: Paraffinic

Specific gravity at 60 °F the specific gravity of a liquid is its density relative to the density of water. The specific gravity of crude oil is typically between 0.8 and 1.0. A specific gravity of 0.88 means that the crude oil is 88% as dense as water.

API° at 60 °F: The API°, or American Petroleum Institute gravity, is a measure of the lightness or darkness of crude oil. A higher API° indicates a lighter crude oil. A crude oil with an API° of 28 is considered to be a medium-heavy crude oil.

Watson characterization factor the Watson characterization factor is a measure of the aromaticity of crude oil. A higher Watson characterization factor indicates a more aromatic crude oil. A crude oil with a Watson characterization factor of 1.014 is considered to be a paraffinic crude oil.

Refractive index the refractive index of a liquid is a measure of how much light is bent when it passes through the liquid. The refractive index of crude oil is typically between 1.4 and 1.5. A refractive index of 1.44 indicates that the crude oil is slightly more refractive than water.

Surface tension the surface tension of a liquid is a measure of the force that acts at the surface of the liquid, tending to minimize the surface area. The surface tension of crude oil is typically between 20 and 30 dyne/cm. A surface tension of 20 dyne/cm indicates that the crude oil has a relatively high surface tension.

Based on the estimated values, the crude oil is likely to be paraffinic. Paraffinic crude oils are characterized by having a high API°, low Watson characterization factor, and low refractive index. They also tend to have a high surface tension.

The absolute maximum and minimum values of the function over the indicated interval and indicate the x-values at which they occur f(x) = x² - 4x - 9; [0, 5],

we need to follow the steps given below:

Step 1: Differentiate the given function to find the critical points and intervals where the function increases and decreases.

f(x) = x² - 4x - 9f'(x)

= 2x - 4= 0

⇒ 2x = 4

⇒ x = 2

Thus, we get a critical point at x = 2.

Now, we will find the intervals where the function increases and decreases using the test point method:

f'(x) = 2x - 4> 0 for x > 2

∴ f(x) is increasing for x > 2.f'(x) = 2x - 4< 0 for x < 2

∴ f(x) is decreasing for x < 2.

Step 2: Check the function values at the critical points and the end points of the interval.

f(0) = (0)² - 4(0) - 9

= -9f(2) = (2)² - 4(2) - 9

= -13f(5) = (5)² - 4(5) - 9

= -19

Step 3: Now, we can identify the absolute maximum and minimum values of the function over the indicated interval

[0, 5].

Absolute maximum value of the function:

The absolute maximum value of the function over the interval [0, 5] is -9 and it occurs at x = 0.

Absolute minimum value of the function:

The absolute minimum value of the function over the interval [0, 5] is -19 and it occurs at x = 5.

Therefore, the absolute maximum and minimum values of the function over the indicated interval [0, 5] and the x-values at which they occur are as follows.

Absolute maximum value = -9 at x = 0

Absolute minimum value = -19 at x = 5
