Step-by-step explanation:

People have given you correct answers but not explained why, perhaps because it seems so obvious.

One of Bayes laws of probability says that if two events e1 and e2 are independent (unrelated), then the probability of both happening together is the product of their individual probabilities.

The die and the coin are independent events. Each is a 50% chance (odd number on a die, heads on a coin). Thus the probability of both happening together is 50% * 50% = 25%.

The probability of obtaining an odd number and a head is 1/4.

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

Let A be Sam rolls a fair dice.

Sample space, s = { [tex]1,2,3,4,5,6[/tex] }

⇒ [tex]n(s)=6[/tex]

An event A is obtaining an odd number, e = { [tex]1,3,5[/tex] }

⇒ [tex]n(e)=3[/tex]

The probability of A is obtaining an odd number,

[tex]P(A)=\frac{n(e)}{n(s)}[/tex]

⇒ [tex]P(A)=\frac{3}{6}[/tex]

⇒ [tex]P(A)=\frac{1}{2}[/tex]

Now, let B be Sam flips a fair coin.

Sample space, s = { [tex]H,T[/tex] }

⇒ [tex]n(s)=2[/tex]

An event B is getting a head, e = { [tex]H[/tex] }

⇒ [tex]n(e)=1[/tex]

The probability of B is getting a head,

[tex]P(B)=\frac{1}{2}[/tex]

Both A and B are independent events.

Thus the probability of obtaining an odd number and a head is

[tex]P(e)= P(A)P(B)[/tex]

⇒ [tex]P(e)=(\frac{1}{2})( \frac{1}{2} )[/tex]

⇒ [tex]P(e)=\frac{1}{4}[/tex]

Hence we can conclude that the probability of obtaining an odd number and a head is 1/4.

Answer:

Dec 10

Step-by-step explanation:

0.25 liter = 250 ml

4 ml * 3 = 12 ml

250/12 = 20.83 days

Nov 20 - Nov 30: 11 days

Dec 1 - Dec 9: 9 days

On December 9, she can still take her 3 doses.

By December 9, she will have taken 12 ml per day for 20 days for a total of 240 ml. She has 10 ml left for Dec 10th.

On Dec 10, she will take 2 doses of 4 ml and 1 dose of 2 ml, and she will finish the medicine.

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Length of remnant fabric = 9.7m

Number of 0.85m length needed for patio = 12

Total length needed = (0.85 * 12) = 10.2m

The length of fabric needed is more than the length of remnant fabric found ;

10.2 m - 9.7m = 0.5m

Hence, Alex will need 0.5m more fabric

Answer:

B

Step-by-step explanation:

There are more consonants in the phrase than vowels so Hal has a better chance of pulling a winning letter. Also, before any tiles have been drawn, Hal has a 9/14 chance of pulling a winning tile while Renee has a 5/14 chance.

Option B is correct.

As given the bag has 14 tiles, each with a letter from the phrase the probability on it.

What is probability?

Probability is nothing but the ratio of number of favorable outcome and total number of outcomes.

Now,

As we know a phrase always consist of vowels and consonants and the number of consonants is always greater than vowels.

Therefore, Hal has better chance of pulling a willing letter. Also before any tiles have been drawn, so Hal has a 9/14 chance of pulling a winning tile while Renee has a 5/14 chance.

Hence, option B is the correct option.

Answer:

-13 = x

Step-by-step explanation:

:))

Answer: x = 13

Step-by-step explanation:

First subtract -4 on both sides because your adding by 4

-x + 4 = -9

    -  4    -4

The 4 - 4 cancels out

So, -9 - 4 is -13

Then we change the sign because we cannot leave x negative.

-x = -13

x = 13

Answer:

Option C. 4.0313×10²⁷ molecules.

Step-by-step explanation:

We'll begin by calculating the volume of oxygen in the room. This can be obtained by calculating the volume of the room since the gas will eventually fill the room.

Width (W) = 5 m

Length (L) = 10 m

Height (H) = 3 m

Volume (V) =?

V = L × W × H

V = 10 × 5 × 3

V = 150 m³

Thus, the volume of oxygen is 150 m³

Next, we shall convert 150 m³ to L. This can be obtained as follow:

1 m³ = 1000 L

Therefore,

150 m³ = 150 m³ × 1000 L / 1 m³

150 m³ = 150000 L

Finally, we shall determine the number of molecules of oxygen in the room. This can be obtained as follow:

22.4 L = 6.02×10²³ molecules

Therefore,

150000 L = 150000 × 6.02×10²³ / 22.4

150000 L = 4.0313×10²⁷ molecules

Thus, the number of molecules of oxygen in the room is 4.0313×10²⁷ molecules

Answer:

60cm^2

Step-by-step explanation:

We assume that is a circumscribing quadrilateral, rather than one that is circumscribed. It is also called a "tangential quadrilateral" and its area is ...

 K = sr

where s is the semi-perimeter, the sum of opposite sides, and r is the radius of the incircle.

 K = (12 cm) (5cm) = 60 cm²

_____

A quadrilateral can only be tangential if pairs of opposite sides add to the same length. Hence the given sum is the semiperimeter.

Hello!

We are given that lines A and B are parallel lines cut by a transversal, and we are comparing the angles of 7 and 2.

We can see immediately that they are alternate exterior angles, because they are on opposite sides of the transversal, and they are on the exterior of the two parallel lines being cut.

According to the Alternate Exterior Angle Theorem, when two parallel lines are cut by a transversal, the resulting exterior angles are congruent, meaning that they are of the same angle measure.

So when it is given that the measure of Angle 7 is 115 degrees, we can conclude that the measure of Angle 2 is 115 degrees as well.
