area of triangle is = 1/2 * base * altitude
1- each side is made 8 times
so the net change in area is 64 times
The area of A'B'C' is 64 times the area of ABC
2- each side is made 4 times
so the net change in area is 16 times
The area of D'E'F' is 16 times the area of DEF
3- each side is made 3 times
so the net change in area is 9 times
The area of A'B'C' is 9 times the area of ABC
50% of babies are born female. Olive wants to find the probability that 20 or more of the 50 babies born today were female. Use the simulation data to find the probability. Round to the nearest percent.
To find the probability that 20 or more out of 50 babies are female, use a binomial distribution with parameters n=50 and p=0.5. Calculate the cumulative probability for P(X ≥ 20). Based on a potential sample output, the probability rounded to the nearest percent is 95%.
Finding the Probability Using Binomial Distribution
The question is about finding the probability that 20 or more out of 50 babies born today are female, given that 50% of babies are born female. This scenario can be modeled using a binomial distribution.
In a binomial distribution, n represents the number of trials (in this case, 50 babies), and p represents the probability of success on a single trial (in this case, the probability of a baby being female, which is 0.5). The binomial distribution formula is:
P(X = k) = (nCk) * (p^k) * ((1-p)^(n-k))
Where nCk represents the combination of n items taken k at a time.
To find the probability that 20 or more out of 50 babies are female, we need to calculate the cumulative probability from 20 to 50:
Use a binomial table or software to find P(X ≥ 20) for n=50 and p=0.5.If using a calculator or software: P(X ≥ 20) = 1 - P(X < 20).After calculating or using a binomial table, you might get a result. For example, suppose the cumulative probability is found to be 0.9523. Rounded to the nearest percent, the probability is 95%.

a triangle has interior angles measuring 36° and 112° which triangles are similar to this triangle select true or false for each triangle
Answer:
Triangle with interior angles measuring 36° and 32°
Triangle with interior angles measuring 32° and 112°
Step-by-step explanation:
we know that
If two triangles are similar, then its corresponding angles are congruent
If two triangles have two equal internal angles, then the triangles are similar by AA Similarity Postulate
step 1
Calculate the measure of the third internal angle
Remember that the sum of the internal angles of a triangle must be equal to 180 degrees
so
Let
x------> the measure of the third internal angle
[tex]x\°+36\°+112\°=180\°\\ \\x=180\°-148\°\\ \\x=32\°[/tex]
step 2
Verify each triangle
case A) Triangle with interior angles measuring 36° and 32°
Is true -----> by AA Similarity Postulate
case B) Triangle with interior angles measuring 36° and 148°
Is false -----> Is not a triangle because the sum of its internal angles is greater than 180 degrees
case C) Triangle with interior angles measuring 32° and 112°
Is true -----> by AA Similarity Postulate
case D) Triangle with interior angles measuring 112° and 148°
Is false -----> Is not a triangle because the sum of its internal angles is greater than 180 degrees

We are given a parallelogram with sides:
3 1/8 and 2 3/16.
Let us convert each into improper fraction.
3 1/8 = 25/8
2 3/16 = 35/16
Now perimeter of parallelogram is given by:
[tex] P = 2(sum of non parallel sides) [/tex]
[tex] P= 2(\frac{25}{8} + \frac{35}{16}) [/tex]
Now we have to find lcd of 8 and 16.
lcd of 8 and 16 is 16.
[tex] P= 2(\frac{25*2}{8*2} + \frac{35}{16} ) [/tex]
[tex] P=2( \frac{50}{16} + \frac{35}{16} ) [/tex]
[tex] P= 2(\frac{50+35}{16} ) [/tex]
Perimeter = 85/8 km
Answer : Perimeter of parallelogram is given by 85/8 km.

what was sal finding when he plugged t=10 into the expression 5t+3?
a. The cost of 10 tickets
b. The cost of 53 tickets
c. The number of tickets that would cost 10 dollars
d. The number of tickets that would cost 53 dollars
Answer:
a. The cost of 10 tickets
Step-by-step explanation:
We don't know what the expression is supposed represent, but the answer choices suggest that ...
c = 5t +3
represents the cost of t tickets. Then, when t=10, c = 53 will represent the cost of 10 tickets.
What is the following product? 4 square root 7
"4√7" means four times the square root of 7, approximately equal to 10.582, an irrational number with decimal expansion.
The expression "4√7" represents the square root of 7, multiplied by 4. Let's break it down step by step:
1. Square Root: The square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 9 is 3 because 3 × 3 = 9. Similarly, the square root of 25 is 5 because 5 × 5 = 25.
2. √7: This symbol (√), called the radical symbol, represents the square root. So, √7 represents the square root of 7, which is an irrational number, meaning it cannot be expressed as a simple fraction and has decimal places that go on indefinitely without repeating.
3. 4√7: This means you're taking the square root of 7 and then multiplying it by 4. So, if you calculate it, it's like doing 4 times the square root of 7.
To give a numerical example, if we want to find the value of 4√7:
4 × √7 ≈ 4 × 2.6457513110645905905016157536393... (approximately)
Thus, 4√7 is approximately equal to 10.582, depending on how many decimal places you round to.
In summary, "4√7" represents four times the square root of 7, which is an irrational number, approximately equal to 10.582.
Which explanation justifies how the area of a sector of a circle is derived?
- Determine how many triangles can fit into a circle. Divide 360° by the number of triangles. Multiply the quotient by the area of the circle .
- Calculate the area of the circle. Then, determine the central angle of the sector and divide this angle by 360° to get a fraction. Multiply the area of the circle by this fraction.
- Partition the circle into unit squares. Determine the area of the sector and multiply the area by the degree of the circle.
- Determine the degree of the sector. Divide by 180° and then multiply it by the area of the triangle the sector is in.
The statement that justifies how the area of a sector of a circle is derived is:
Calculate the area of the circle. Then, determine the central angle of the sector and divide this angle by 360° to get a fraction. Multiply the area of the circle by this fraction.What is an area?This refers to the quantity that expresses the extent of a region on the plane such as on a curved surface.
Furthermore, the area of sector of a circle is talking about the amount of space enclosed within the boundary of the sector.
Generally, it is explained in step that we first calculate the area of the circle. Then, determine the central angle of the sector and divide this angle by 360° to get a fraction. Multiply the area of the circle by this fraction.
Therefore, the Option B is correct.

Stewart wants to know how many students in his school enjoy watching sports on TV. He asks this question to all 25 students in his science class and finds that 60% of his classmates enjoy watching sports on TV. He claims that 60% of the school's student population would be expected to enjoy watching sports on TV. Is Stewart making a valid inference about his population?
Yes, it is a valid inference because he asked all 25 students in his science class
Yes, it is a valid inference because his classmates make up a random sample of the students in the school
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school
No, it is not a valid inference because he asked all 25 students in his science class instead of taking a sample from his math class
Answer:
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school.

The smaller rectangle was scaled by a factor of 4 to produce the larger figure.
Use the drop-down menus to show the missing dimensions of the scaled figure.
Answer:
Step-by-step explanation: so the problem is asking for the missing dimensions of the rectangle. The smaller rectangle has a length of 12 inches, a width of 8 inches, and an area of 96 inches. To clarify, 8x12 is 96 so when looking at the bigger rectangle, it says that it was scaled by a factor of 4.
The Answer-
Length:48
Width:32
Area:1,536
