Answer:
P(A ∪ B) = P (A) + P(B) – P(A ∩ B)
Step-by-step explanation:
Conditional probability: p(A|B) is the probability of event A occurring, given that event B occurs. For example, given that you drew a red card, what's the probability that it's a four (p(four|red))=2/26=1/13. So out of the 26 red cards (given a red card), there are two fours so 2/26=1/13.

4 miles per hour
Step-by-step explanation:Unit rate is the rate of something per 1 unit. In other words, the unit rate is x units per 1 unit. In this situation, the unit rate is how many miles Hassan walks in 1 hour.
Proportion
First, to find the rate of anything we can set up a proportion. In the question, the rate is described as miles per hour, so the miles will be the numerator and the hours will be the denominator.
This creates the proportion [tex]\frac{12miles}{3hours}[/tex]So, the rate we are given is 12/3.
Unit Rate
To find the unit rate we need to make the denominator equal to 1. To do this, divide both the numerator and denominator by 3.
12/3 equals 43/3 equals 1So, this means that the new proportion is 4/1. Next, we can add our units, which means that Hassan walks 4 miles per 1 hour.
Graph
Now we can resize the bar graph. The purple bar should be set to 4 because this represents the miles. Then, the green bar should be set to 1 because it represents the hours.

A) It's rational because 5.78 = 526/2 33.
B) It's irrational because 5.78 = 5.787878.
C) It's irrational because 5.78= 5.787878.
D) It's rational because 5.78 = 5.787878.
its rational - 5.78 = 5.787878.
D.
explanation:
We have been given a number 5.78. We are asked to choose the correct statement which shows that 5.78 is a rational number.
Upon looking at our given choices, we can see that only option A is the correct choice as it has repeating digits (78) after decimal.
We know that a number with repeating decimals can be written as a fraction, therefore, option D is the correct choice.

Find the area of the clock
Use 3.14 for pi
Area = PI x radius^2
The diameter is given as 25 inches, the radius is 1/2 the diameter.
Radius = 25/2 = 12.5 inches
area = 12.5^2 x 3.14
Area = 490.625 square inches

pls help this is due tomorrow morning and it's 1 am I'll mark brainliest 15 points each
Answer:
Let [tex]\pi[/tex] represent 3.14
SA = 2[tex]\pi[/tex]r^2 + 2[tex]\pi[/tex]rh
SA = 2[tex]\pi[/tex](5)^2 + 2[tex]\pi[/tex](5)(12)
SA = 2[tex]\pi[/tex](25) + 2[tex]\pi[/tex](60)
SA = 50[tex]\pi[/tex] + 120[tex]\pi[/tex]
SA = 50(3.14) + 120(3.14)
SA = 157 + 376.8
SA = 533.8inch^2
Therefore the surface area of the cylinder is 533.8 square inches.
Answer: Let represent 3.14SA = 2r^2 + 2rhSA = 2(5)^2 + 2(5)(12)SA = 2(25) + 2(60)SA = 50 + 120SA = 50(3.14) + 120(3.14)SA = 157 + 376.8SA = 533.8inch^2

which is faster: drive a car at a rate of 40 kilometers per hour or drive a car at a rate of 15 meters per second
Answer:
Step-by-step explanation:
Let's convert one of these measurements so that both measurements have the same units. 15 m/sec is equivalent to 0.015 km/sec, which in turn is equivalent to
0.015 km 3600 sec
--------- -------- ----------------- = 54 km/hr
1 sec 1 hr
This latter result (54 km/hr) is faster than (40 km/hr).

Answer:
√689 ≈ 26.2 leagues
Step-by-step explanation:
For the purpose of calculating the distance between the marked points, the line is considered to be the hypotenuse of a right triangle. The horizontal distance between the points is one leg of the triangle, and the vertical distance is the other leg. The Pythagorean theorem relates these distances.
Pythagorean relationThe Pythagorean theorem relates right triangle sides 'a' and 'b' to hypotenuse 'c' with the formula ...
c² = a² +b²
Taking the square root, we have an expression for 'c' in terms of 'a' and 'b'.
c = √(a² +b²)
Application to distanceThe horizontal distance between the points is the difference of their x-coordinates:
a = x2 -x1 = 2 -(-18) = 20
The vertical distance between the points is the difference of their y-coordinates:
b = y2 -y1 = -10 -7 = -17
When we square these numbers, we find their signs to be irrelevant.
c = √(a² +b²) = √(20² +(-17)²) = √(400 +289) = √689
c ≈ 26.249
The distance between the given points is about 26.2 leagues.
