4(3)+2/2
Use PEMDAS
12+2/2
14/2
Divide
7
If you replace x with 3, you are left with the equation 4(3)+2 divided by 2. When you multiply you get 12+2=14/2 is 7

Scott Disick is known for his club scene. Although he is optimistic about the nightlife in Philly, he is more of a NYC guy when he is in the East Coast. He is concerned about the overall quality of the nightlife. He believes the probability is 0.50 that the scene will be excellent, 0.20 that it is average and 0.30 that the scene will not be up to his standards. He also estimates that the probability of Leo Di Caprio coming in an excellent scene will be 0.7, the probability of him coming at an average setting it is 0.3 and the probability that it will not be up this standards at .2 List out the probabilities of an excellent scene, an average scene and a below standards scene.

Answers
Answer:
1.)
P(E) = 0.5
P(A) = 0.2
P(N) = 0.3
Conditional probability ;
0.47
Step-by-step explanation:
Let :
E = Excellent ; A = Average ; N = not up to standard
P(E) = 0.5
P(A) = 0.2
P(N) = 0.3
If Leo shows up ; this type of probability is called a conditional probability. It is the likelihood of an event based on a certain or already satisfied condition.
The probability that Leo is coming :
Leo ; Excellent = 0.7
Leo ; Average = 0.3
Leo; Not up to standard = 0.2
Hence, probability they Leo is coming :
(0.5 * 0.7) + (0.2 * 0.3) + (0.3 * 0.2)
0.35 + 0.06 + 0.06
= 0.47

The length of a planet's orbit around a star is approximately 17,680,000 km.
It takes the planet about 860 Earth days to complete a full orbit.
What is the planet's average speed in kmh 1 to 3sf?
Answers
Answer: 856.59 km/h
Step-by-step explanation:
Length of a planet's orbit around a star = 17,680,000 km.
Days to complete full orbit = 860 days
Number of hours to complete full orbit = 860 × 24 hours = 20640 hours
The planets average speed in km/h will be:
= Distance / Time
= 17,680,000 / 20640
= 856.59 km/h
Note: 24 hours = 1 day

If there are 48 double decker buses in a depot and 24 single, what percentage of the buses are single decker?
Answers
Answer:
17.28
Step-by-step explanation:
Totall buses: 48+28 = 72
% Of single decker: 72×(24÷100) = 17.28
Approximately 33.33 percentage of the buses in the depot are single-decker buses.
To find the percentage of single-decker buses, we need to calculate the ratio of the number of single-decker buses to the total number of buses (single-decker and double-decker) and then multiply by 100.
The total number of buses in the depot is given as 48 double-decker buses + 24 single-decker buses = 72 buses.
The number of single-decker buses is 24.
The ratio of single-decker buses to the total number of buses is 24 buses / 72 buses = 1/3.
To find the percentage, we multiply the ratio by 100:
(1/3) * 100 = 33.33%
Therefore, approximately 33.33% of the buses in the depot are single-decker buses.

A scientist is studying the relationship of two quantities S and T in an experiment. The scientist finds that
under certain conditions, as the quantity of S increases, the quantity of T decreases. After taking
measurements, the scientist determines that the rate of change of the quantity of S with respect to the
quantity of T present is inversely proportional to the natural logarithm of the quantity of T. Which of the
following is a differential equation that could describe this relationship?
Answers
Differential equation is a way to represents the function and its variable by relating them.Hence the differential equation that describe the relationship between S and T is,
[tex]S \propto \dfrac{1}{log_e T}[/tex]
Given-
The quantity of S increases, the quantity of T decreases.
The rate of change of the quantity of S with respect to the quantity of T present is inversely proportional to the natural logarithm of the quantity of T.
What is differential equation?Differential equation is a way to represents the function and its variable by relating them.
As the quantity of S changes with respect to the quantity of T present is inversely proportional. Thus,
[tex]S \propto \dfrac{1}{T}[/tex]
But quantity of S changes inversely proportional to the natural logarithm of the quantity of T. The natural logarithm of a number is its logarithm to the base of e (constant).
Thus the equation can be given is,

how do i factorise x^2+6x-40 ?
Answers
9514 1404 393
Answer:
(x +10)(x -4)
Step-by-step explanation:
Compare the factored and expanded forms:
(x +p)(x +q) = x^2 +(p+q)x +pq = x^2 +6x -40
That is, the constants in the binomial factors will be factors of -40 that have a sum of 6. This is where your knowledge of multiplication tables is helpful.
-40 = -1×40 = -2×20 = -4×10 = -5×8
The sums of these factor pairs are 39, 18, 6, 3, respectively. So, the one we want is (-4)(10) = -40. Now that we know the values of 'p' and 'q', we can write the factorization ...
x^2 +6x -40 = (x -4)(x +10)
