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:

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%.

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

Hello!

A cylinder has a radius of 14m and a height of 6m what is the exact volume of this cylinder

Data:

r (radius) = 14 m

h (height) = 6 m

v (volume) = ?  

Formula:

[tex]V = \pi *r^2*h[/tex]

Solving:

[tex]V = \pi *r^2*h[/tex]

[tex]V = \pi *14^2*6[/tex]

[tex]V = \pi *196*6[/tex]

[tex]\boxed{\boxed{V = 1176 \pi\:m^3}}\end{array}}\qquad\quad\checkmark[/tex]

if, we adopt:  π= 3.14, so:

[tex]V = 1176*\pi \to V = 1176*3.14 \to \boxed{\boxed{V \approx 3692.64\:m^3}}\qquad\quad\checkmark[/tex]

Answer:

Point E on the number line represents the approximate volume of a cylinder with a radius of 4 units and height of 4 units.

Step-by-step explanation:

It is given that the radius of the cylinder is 4 units and the height of the cylinder is 4 units.

The volume of the cylinder is

[tex]V=\pi r^2h[/tex]

Where, r is radius and h is height of the cylinder.

Substitute r=4, h=4, π=3.14 in the above formula.

[tex]V=(3.14)\times (4)^2\times (4)[/tex]

[tex]V=200.96[/tex]

The volume of  the cylinder is 200.96. Therefore, point E on the number line represents the approximate volume of a cylinder with a radius of 4 units and height of 4 units.

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

Answer:

agree

Step-by-step explanation:

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.

56 is 0.8 as a decimal fraction of 70.

A fraction represents a part of a whole.

We have to find Fifty six is what decimal part of 70

To find what fraction 56 is of 70,

We have to divide Fifty six by seventy

56 / 70 = 0.8

Therefore, 56 is 0.8 as a decimal fraction of 70.

The statement that justifies how the area of a sector of a circle is derived is:

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.

"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.
