If we know that at least one of the dice is a 4, the probability that the sum of the two dice will be equal to 7 is 1/3.
The probability that the sum of two dice will be equal to seven if we know that at least one of the dice is a 4 can be calculated as follows:
There are two cases to consider:
The first die is a 4 and the second dice can be any value from 1 to 6. The probability of this event is 1/6.The second die is a 4 and the first dice can be any value from 1 to 6. The probability of this event is also 1/6.Since the two events are mutually exclusive, the total probability that the sum of the dice will be equal to 7 is the sum of the individual probabilities, which is
1/6 + 1/6 = 2/6 = 1/3.
In conclusion, if we know that at least one of the dice is a 4, the probability that the sum of the two dice will be equal to 7 is 1/3. This means that there is a 1 in 3 chance of getting a sum of 7 when rolling two dice and knowing that at least one of the dice is a 4.

Riggoletto's Portraits specializes in making circular portraits of people. A large portrait is 18 in. In diameter. A medium portrait is 6 in. In diameter. Estimate the difference between the areas of the two sizes of portraits. Use 3. 14 for T. Round your answer to the nearest whole number.
The estimated difference between the areas of the two sizes of portraits is 226.
First, find the area of the large portrait:
A = πr^2 = π(9)^2 = 3.14 * 81 = 253.94
Next, find the area of the medium portrait:
A = πr^2 = π(3)^2 = 3.14 * 9 = 28.26
Finally, subtract the area of the medium portrait from the area of the large portrait to find the difference:
253.94 - 28.26 = 225.68
Rounding to the nearest whole number, the difference is 226.

Step-by-step explanation:
Condition:
A linear relationship is proportional if the ratio of the change in the dependent variable to the change in the independent variable is constant. This constant is known as the proportionality constant and can be represented by "k" in the equation y = kx. When a linear relationship is proportional, there is a direct relationship between the variables and as one increases, the other increases and vice versa.
The second table (x = -2, -1, 0 and y = -1, 0, 1) represents a linear relationship that is also proportional. A proportional relationship means that the ratio of y to x remains constant, or in other words, y is a constant multiple of x. In this table, for every 1 unit increase in x, y increases by 1 unit, making it proportional.
The third table represents a linear relationship that is also proportional.

parallelogram AB'C' D'?
A parallelogram is a two-dimensional shape with four straight sides that are parallel to one another and with opposite sides that are of equal length. The parallel and equal lengths of the opposing sides give the shape its name.
What is the dilating parallelogram?A rectangle that has been extended or contracted in one direction, or two congruent adjacent rectangles combined, can be used to describe a parallelogram.
a. The scale factor, when a dilation is carried out with centre of dilation A, is the ratio of the lengths of the corresponding sides of the pre-image and image. If the parallelograms ABCD and AB'C'D' have equivalent sides with lengths of AB and AB', respectively, the scaling factor is AB'/AB.
b. Set n equal to the total number of parallelograms ABCD that can fit inside parallelogram AB'C'D'.
Then, by multiplying the area of the parallelogram AB'C'D' by the area of the parallelogram ABCD, the area of the parallelogram AB'C'D' is equal to n times the area of the parallelogram ABCD.
c. The area of the parallelogram AB'C'D' is exactly proportional to the area of the parallelogram ABCD; as a result, if the scale factor of the dilation is k, the area of the parallelogram AB'C'D' is equal to k2 times the area of the parallelogram ABCD.
d. If the area of parallelogram ABCD is 12 square units, then the area of parallelogram AB'C'D' is equal to k2, or k2 times, the area of parallelogram ABCD.
Therefore, A parallelogram's adjacent sides and opposite sides combine to form a pair of neighbouring angles and two parallel lines, respectively.

some of our farm fields are being left unused. does this have any implications for the economy's ppf diagram (with agricultural products on one axis and all other products on the other axis)?
Yes, the implications of leaving farm fields unused for the economy's PPF diagram can be seen in the output of agricultural products.
The PPF diagram shows the maximum output of two products that an economy can produce at a given time, and it is shaped like a curve. When farm fields are left unused, the amount of agricultural products that can be produced is decreased, resulting in a shift in the PPF curve inwards. This means that the economy has to sacrifice other goods to maintain the same level of production of agricultural products, leading to an opportunity cost. Thus, leaving farm fields unused has implications for the economy's PPF diagram, as it reduces the output of agricultural products, resulting in a shift in the PPF curve inwards.

How long does it take for a deposit of $1400 to double at 5% compounded continuously?
Deposit of $1400 will be double in 14.2 years.
What is compound interest?Compound interest is the interest calculated on the principal and the interest accumulated over the previous period. It is different from simple interest, where interest is not added to the principal while calculating the interest during the next period.
Given,
Deposited Principal Amount P = $1400
Rate of interest r = 5% = 0.05
Amount A = double the deposit = 2× $1400 = $2800
Let the number of years = n
Amount A = P(1 + r)ⁿ
$2800 = $1400(1 + 0.05)ⁿ
(1 + 0.05)ⁿ = 2
Taking log on both side
n log(1.05) = log2
n = log2 / log(1.05)
n = 0.3010/0.0212

Using the fact that the sum of the interior angles must be 180°, we will get:
∠B = 101°
XYZ = 76°
How to find the measure of angle B?Let's solve the problem for the first triangle.
Ok, remember that the sum of the interior angles of any triangle is always equal to 180°, then we can write:
∠B + ∠C + ∠A = 180°
Replacing the values that we know we will get:
∠B + 44° + 35° = 180°
Now we can solve that equation to get:
∠B = 180° - 44° - 35° = 101°
So the answer is 101°.
For the second triangle, the interior angles are:
(5x + 1)
(3x + 11)
And, the one at the right is:
180° - 12x + 20
Then the sum gives:
(5x + 1) + (3x+ 11) + 180° - 12x + 20 = 180
5x + 1 + 3x + 11 - 12x + 20 = 0
-4x + 32 = 0
-4x = -32
x = 32/4 = 8

Answer: Diploid cells divide to form four haploid daughter cells during mitosis.
Step-by-step explanation:
The answer is: Sister chromatids separate to form haploid daughter cells during meiosis.
What is chromatids?One of a chromosome's two identical halves that has undergone replication in order to facilitate cell division is referred to as a chromatid. A chromosomal region known as the centromere is where the two "sister" chromatids are fused.
One of the two identical copies of a duplicated chromosome is called a chromatid. At the centromere, a portion of the chromosome, the twin copies of the DNA join together during cell division. Sister chromatids are those that are joined. A chromosome is a protein and DNA-based structure that resembles a thread. It contains an organism's whole genetic makeup. Parents pass this on to their children. One of a chromosome's halves is called a chromatid. There is just one chromatid per chromosome.
The chromatids in each thread-like structure in the chromosome are the result of the chromosome's DNA replicating itself. Haploid cells are produced as a result of the segregation of the chromatids during meiosis II.

To determine the number of rectangles needed to achieve a desired accuracy, one could start with a small number of rectangles, calculate the approximation error, and then increase the number of rectangles until the error is within the desired range.
How determine the number of rectangles?The number of rectangles to use in a rectangle approximation of a definite integral depends on several factors:
The desired accuracy: The smaller the desired accuracy, the more rectangles will be required.
The shape of the function: If the function is highly curved, more rectangles will be required to capture the shape of the function than if the function is more linear.
The range of integration: The larger the range of integration, the more rectangles will be required.
In general, to determine the number of rectangles needed to achieve a desired accuracy, one could start with a small number of rectangles, calculate the approximation error, and then increase the number of rectangles until the error is within the desired range. Alternatively, one can use mathematical techniques such as adaptive quadrature methods that automatically adjust the number of rectangles to achieve a desired accuracy.

1/3 of the cake was left. The next day, George ate half of what was left. Choose the model that shows what fraction of cake George ate.
Answer: 4 aka the one on the bottom
Step-by-step explanation: There is 3 sections, only one filled in to make 1/3, then you split that in half
Answer:
1/6
Step-by-step explanation:
If we know that only 1/3 of the ice cream cake was left, and George ate 1/2 of that, we can use the equation:
1/3 ÷ 2 = 1/6
If we were to divide a fraction, we would take the denominator, in this case its 3, and multiply that by the amount being divided, which is 2.
2 × 3 = 6
Now that we have 6, simply add it back to the fraction denominator with the same numerator which is 1. This would make it 1/6.
Therefore, the picture that best matches this is the last one.
