what is the probability that a family of two children has two boys given that the first child is a boy
Since the first child is a boy, this means we need to find the probability of another boy. This is 1/2 since we assume each gender has the same chance of happening.
A man has extra digits (six fingers on each hand and six toes on each foot). His wife and their daughter have a normal number of digits. Having extra digits is a dominant trait. The couple's second child has extra digits. What is the probability that their next (third) child will have extra digits?.
The probability that their next (third) child will have extra digits is 0.5
Polydactyly refers to the presence of extra fingers in the human body. It is a hereditary condition that is passed down from parents to children. The thumb, middle, and little fingers are the most commonly affected by this condition. Polydactyly refers to the presence of extra fingers in the human body. It is a hereditary condition that is passed down from parents to children. The thumb, middle, and little fingers are the most commonly affected by this condition.
A trait is a distinguishing characteristic that a person possesses. Dominant traits are defined as having only one copy of a gene on a chromosome that expresses a specific trait.
Individuals exhibit the dominant traits most prominently. Polydactyly is the dominant condition in this case.
The father has six fingers and six toes, while the mother is in normal condition. In this particular condition, polydactyly is a dominant trait. Twelve percent of the couple's children are expected to have extra digits.
Because the father has the dominant trait and the mother is in normal condition, there is a 50% chance that this deformity will be passed down to children.
The probability that their next child will have extra digits is 0.5

The values of the variables "a", "b", and "c" are 3.06, 169.74, and 0, respectively. The total amount Gary will pay is $769.74.
Gary purchased a S750 TV on a credit card with a 22% annual percentage rate, and he wants to pay it off in payments of $200 per month. The table shows the information for the first four months after Gary used his credit card. We need to calculate the values of the missing variables and the total amount he will pay.
The variable "a" is the interest charged on the left amount in the third month.
a = (366.68 - 200)*0.018333 = 3.06
The variable "b" is the monthly amount paid by Gary. It is less than or equal to $200, depending on the payment amount. Since the amount to be paid is $169.74, which is less than $200, he will pay the whole amount in one go.
b = 169.74
The variable "c" is the interest charged on the left amount in the fourth month. Since then, the entire amount has been paid.

A prefect is to be chosen from 15 girls and 8 boys. What is the probability that the prefect is a girl?
Answer:
0.6522 or 65.22%Step-by-step explanation:
Total number of candidates is:
15 + 8 = 23Probability of a girl to be chosen as prefect:
P(girl) = number of girls / total number of candidatesP(girl) = 15/23 = 0.6522 or 65.22%Answer:
Probability = 15/23
Step-by-step explanation:
Now we have to,
→ find probability that prefect is a girl.
The total members are,
→ 15 girls + 8 boys
→ s = 15 + 8
→ [ s = 23 ]
Then the probability will be,
→ P = 15/s
→ [ P = 15/23 ]
Hence, the answer is 15/23.

a. Constant of proportionality is equal to 5.
b. Point (12, 60) represents that 12 pounds of sugar required to make 60 cups of coffee.
What is graph ?The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.
In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.
Usually, data that varies over time is represented with a line graph.
Given:
We have the relation between total number of cups of coffee and the total amount of sugar:
Let y represents the number of cups of coffee
and, x represents the amount of sugar
y ∝ x
y = kx
a. 'k' is the constant of proportionality
When y = 20 , x = 4
20 = k × 4
k = 20/ 4
k = 5
b. From the graph point (12, 60) represents 12 is on the x-axis and y is on the y-axis.
12 represents amount of sugar and 60 represents the number of cups of coffee.
Hence, the Constant of proportionality is equal to 5.

Let us take x =1
Now substitute the x vale in student 1 expression
1/4(10 x+8) = -(1/2 x +13)+3(x +5)
1/4(10 (1)+8) = -(1/2 (1)+13)+3(1 +5)
1/4(18) = (-1/2 -13)+3(6)

Determine the convergence of divergence of the sequence. If the sequence converges, find its limit.
The sequence converges and its limit is zero
What is a sequence?A sequence is an ordered set of numbers governed by a rule.
What is the limit of a sequence?The limit of a sequence is the value the sequence approaches
What is convergence of a sequence?The convergence of a sequence is when the sequence approached a definite value
What is divergence of a sequence?The divergence of a sequence is when the sequence does not approach a definite value.
How to determine the convergence of divergence of the sequence?Since we have the sequence (√3 - √1), (√4 - √2), (√5 - √3), (√6 - √2), We need to find the general term of the sequence.
Observing this, we find that the general term Uₙ = √(n + 2) - √n
To determine if the limit converges or diverges, we take the limit of the sequence as n → ∞.
So,
[tex]\lim_{n \to \infty} U_n = \lim_{n \to \infty} \sqrt{n + 2} - \sqrt{n} \\= \lim_{n \to \infty} \sqrt{n + 2} - \lim_{n \to \infty} \sqrt{n} \\= \sqrt{\infty - 2} - \sqrt{\infty} \\= \sqrt{\infty} - \sqrt{\infty} \\= \infty -\infty[/tex]
Since this is an indeterminate form, we use L'hopital's rule to find the limit.
Uₙ = √(n + 2) - √n
= √n{√[(n + 2)/n] - 1}
= √n÷ 1/{√[(1 + 2/n] - 1}
Differentiating, we have
lim n → ∞ Uₙ = lim n → ∞ d√n/dn ÷ d(1/{√[(1 + 2/n] - 1})/dn
= 1/(2√n)/-√[(1 + 2/n] - 1})⁻² × 1/2√(1 + 2/n] × (-2/n²)
= n²[√(1 + 2/n] - 1})²/(2√n)√(1 + 2/n]
= n²[√(1 + 2/n] - 1})²/(2√n)√(1 + 2/n)]
Dividing through by n², we have
= n²[√(1 + 2/n] - 1})²/n² ÷ (2√n)√(1 + 2/n)]/n²
= [√(1 + 2/n] - 1})² ÷ (2(√n)³√(1 + 2/n³)]
Dividing both the numerator and denominator by (√n)³, we have
= [√(1 + 2/n] - 1})²/(√n)³ ÷ (2(√n)³√(1 + 2/n³)]/(√n)³
= (1 + 2/n] - √(1 + 2/n] + 1)/(√n)³ ÷ [2√(1 + 2/n³)]
= (1(√n)³ + 2/n²] - √{(1 + 2/n]/n)³} + 1/(√n)³) ÷ [2√(1 + 2/n³)]
= (1(√n)³ + 2/n²] - √{(1/n³ + 2/n⁴} + 1/√n)³) ÷ [2√(1 + 2/n³)]
So, lim n → ∞ Uₙ = lim n → ∞ (1(√n)³ + 2/n²] - √{(1/n³ + 2/n⁴} + 1/√n)³) ÷ [2√(1 + 2/n³)]
= (1(√∞)³ + 2/∞²] - √{(1/∞³ + 2/∞⁴} + 1/√∞)³) ÷ [2√(1 + 2/∞³)]
= (0 + 0] - √{(0 + 0} + 0) ÷ [2√(1 + 0)]
= (0 - 0 + 0)/2
= 0/2

A. 45°, 65°, 70° C. 40°, 60°, 80°
B. 50°, 60°, 70° D. 60°, 60°, 60°
The angles of the triangle will be 50°, 70°, 60° .
let the 3 angles of a triangle be A, B and C
The first acute angle A is given by = x + 20
The second acute angle B is given by = 2x + 10
The third acute angle C is given by = 4x - 60
Now we know that the sum of the angles of a triangle is 180°
So ,
A + B + C + = 180°
x + 20 + 2x + 10 + 4x - 60 = 180°
7x - 30 = 180°
7x = 210°
x = 30°
So, from the value of x , we can calculate the value of each angle
Therefore, the required angles are :
angle A = (x + 20)° = 30° + 20° = 50°
angle B = (2x + 10)° = 60° + 10° = 70°
angle C = (4x - 60)° = 120° - 60° = 60°
