As per question, point B is the midpoint of AC.

According to definition of midpoint, AB = BC:

The length of AB is:

Answer:

AB = 18

Step-by-step explanation:

To find:-

Answer:-

We are here given that points A , B and C are collinear and B is the midpoint of AC . From the data provided in the question we have;

Since B is the midpoint of AC, it will divide AC into two equal parts namely AB and BC. And these parts will be equal to one another. ( By Euclid's first axiom, Things which are half of the same thing are equal to one another.)

So we have;

[tex]\sf:\implies AB = BC \\[/tex]

[tex]\sf:\implies 3x = 4x - 6 \\[/tex]

[tex]\sf:\implies 3x -4x = -6 \\[/tex]

[tex]\sf:\implies -x = -6 \\[/tex]

[tex]\sf:\implies\red{ x = 6} \\[/tex]

Finally plug in the value of x, in the given expression of AB as ,

[tex]\sf:\implies AB = 3(x) \\[/tex]

[tex]\sf:\implies AB = 3(6) \\[/tex]

[tex]\sf:\implies \red{AB = 18} \\[/tex]

Hence the value of AB is 18 .

To determine whether 360 is prime, composite, or neither, we need to check if it has any factors other than 1 and itself.

We can start by finding the prime factorization of 360:

First, we can divide 360 by 2 to get 180:

360 ÷ 2 = 180

Next, we can divide 180 by 2 to get 90:

180 ÷ 2 = 90

We can continue dividing by 2 until we can no longer divide evenly:

90 ÷ 2 = 45

45 ÷ 3 = 15

15 ÷ 3 = 5

5 is a prime number, so we have found the prime factorization of 360:

360 = 2 × 2 × 2 × 3 × 3 × 5

Therefore, we can see that 360 is composite because it has more than two factors. We can write it as the product of its prime factors as shown above.

In summary, the number 360 is composite and its prime factorization is:

360 = 2 × 2 × 2 × 3 × 3 × 5

The population of the town after 12 years Aand in 24 years will be approximately 34,461 and 79,171 respectively.

If the population doubles every 10 years, then we can use the formula for exponential growth to find the population after a certain number of years:

P = P₀ x 2^(t/T)

where:

P₀ = initial population = 15,000

P = population after t years

T = doubling time = 10 years

t = number of years

Using this formula, we can find the population after 12 years:

P = 15,000 × 2^(12/10)

P = 34,461

Therefore, the population of the town after 12 years will be approximately 34,461.

Similarly, we can find the population after 24 years:

P = 15,000 ×  2^(24/10)

P = 79,171

Therefore, the population of the town after 24 years will be approximately 79,171.

Corsica adds 3/32 = 0.09375 ounces of water to the bucket per second.

To find how many ounces of water are added to the bucket per second, we need to rearrange the given equation to solve for the rate of change of the water, which is the change in the amount of water per unit of time.

Starting with:

3W = 32S

We can divide both sides by S:

3W/S = 32

Now we can see that the left-hand side represents the amount of water (in ounces) added per second, since W/S is the rate of change of the water with respect to time.

Therefore, we can conclude that Corsica adds 3/32 = 0.09375 ounces of water to the bucket per second.

Answer:

≈ 9.9 feet

Step-by-step explanation:

We can use the Pythagorean theorem to solve this problem. Let x be the distance from the house to the base of the ladder. Then:

x^2 + 15^2 = 18^2

Simplifying and solving for x, we get:

x = sqrt(18^2 - 15^2) = 9.9 feet (rounded to the nearest tenth)

Therefore, Jaquira should place the base of the ladder approximately 9.9 feet away from the house.

The probability that a red ball was selected more than 20 times when 25 balls are randomly selected from the jar with replacement is 0.037.

Given that a jar contains 30 red balls and 20 white balls. Also, 25 balls are randomly selected from the jar with replacements. We need to find the probability that a red ball was selected more than 20 times.

The binomial probability distribution function can be represented as follows:
[tex]P(X = k) = \ ^nC_k . p^k . q^{(n-k)}[/tex]
where n is the number of trials, k is the number of successes,

p is the probability of success,

q = 1 - p is the probability of failure.
Here, the probability of selecting a red ball is 30/50 = 3/5.

So, the probability of selecting a white ball is 2/5.
Here, we have n = 25 trials, p = 3/5, q = 2/5.

Let X be the number of times a red ball is selected. Then we need to find P(X > 20).
So, P(X > 20) = 1 - P(X ≤ 20)
= 1 - Σ P(X = k), k = 0 to 20
[tex]= 1 - \sum \ ^nC_k . p^k . q^{(n-k)}[/tex], k = 0 to 20
[tex]P(X = k) = \ ^nC_k . p^k . q^{(n-k)}[/tex]

[tex]P(X > 20) = 1 - \sum \ ^nC_k . p^k . q^{(n-k)}[/tex], k = 0 to 20

= [tex]1 - { \ ^nC_0 . p^0 . q^{(n-0)} + \ ^nC_1 . p^1 . q^{(n-1)} + \ ^nC_2 . p^2 . q^{(n-2)} + ... + \ ^nC_{20} . p^{20} . q^{(n-20)}}[/tex]
= 1 - {1 . (3/5)^0 . (2/5)^25 + 25 . (3/5)^1 . (2/5)^24 + 300 . (3/5)^2 . (2/5)^23 + ... + 1.623 x 10^10 . (3/5)^20 . (2/5)^5}
= 1 - 0.963
= 0.037

Therefore, the probability that a red ball was selected more than 20 times when 25 balls are randomly selected from the jar with replacement is 0.037.

Answer:

37 customers preferred cake.

Step-by-step explanation:

A percentage is a ratio or a number expressed in the form of a fraction of 100. Percentages are often used to express a part of a total.

To find out how many customers preferred cake, we need to multiply the total number of customers (105) by the percentage of customers who preferred cake (35%):

(35% = 0.35)

Rounding this to the nearest whole number gives us 37. Therefore, approximately 37 customers preferred cake.

Answer:

35% of 105 is 36.75. ( Rounded up 37). So 37 customers preferred cake the most

Let's represent the total distance that Mira plans to run with "x".

According to the problem, 2 miles is 40% of the total distance, so we can write:

2 = 0.4x

To find the value of "x", we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.4:

2 ÷ 0.4 = x

Simplifying the left side gives us:

5 = x

Therefore, Mira plans to run a total of 5 miles.

The width of the rectangle is 3/2 cm and the length is 17 cm.

The formula for the area of a rectangle is A = L x W, where A is the area, L is the length, and W is the width. To solve this problem, we can rearrange the formula to solve for W: W = A / L. In this case, A = 6 cm and L = 2W + 11 cm. Substituting these values, we get W = 6 / (2W + 11). We can solve this equation by dividing both sides by 2W to get 1/W = 6 / (2W + 11) * 1/2W. Simplifying, we get 1/W = 3 / (11 + 2W). Subtracting 3/11 from both sides, we get -2/11 W = -3/11. Finally, we can solve for W by dividing both sides by -2/11 to get W = 3/2 cm.

Therefore, the width of the rectangle is 3/2 cm, and the length of the rectangle is 2W + 11 = 11 + 6 = 17 cm.

The Midsegment Theorem states that the segment joining the midpoints of two sides of a triangle is parallel to and half the length of the third side.

This simply means that:

The middle segment = half the third side

From the image:

Using the Midsegment Theorem

x + 10 = 1/2 × (x + 23)

Solve for x

Multiply both sides by 2

2( x + 10 ) = 1/2 ×2 (x + 23)

2( x + 10 ) = x + 23

2x + 20 = x + 23

Answer: The correct answer is:

The y-intercept is 3.79, which means a student with no absences is predicted to have a GPA of 3.79.

Explanation:

To determine the relationship between the number of absences and the GPA, the student can use linear regression analysis. The regression line can be obtained using software such as Excel or R. The y-intercept of the regression line represents the predicted value of the response variable (GPA) when the predictor variable (number of absences) is zero.

Using technology, the y-intercept for this data set is found to be 3.79. This means that a student with zero absences is predicted to have a GPA of 3.79. Therefore, the correct answer is that the y-intercept is 3.79 and it does make sense to interpret it in this context.
