Answer:
Step-by-step explanation:
For this triangle we have to
We want to find the length of b
We know that the sum of the internal angles of a triangle is 180 °
So
Now we use the sine theorem to find the length of b:
Then:
Answer:
The probability of selecting a black card or a 6 = 7/13
Step-by-step explanation:
In this question we have given two events. When two events can not occur at the same time,it is known as mutually exclusive event.
According to the question we need to find out the probability of black card or 6. So we can write it as:
P(black card or 6):
The probability of selecting a black card = 26/52
The probability of selecting a 6 = 4/52
And the probability of selecting both = 2/52.
So we will apply the formula of compound probability:
P(black card or 6)=P(black card)+P(6)-P(black card and 6)
Now substitute the values:
P(black card or 6)= 26/52+4/52-2/52
P(black card or 6)=26+4-2/52
P(black card or 6)=30-2/52
P(black card or 6)=28/52
P(black card or 6)=7/13.
Hence the probability of selecting a black card or a 6 = 7/13 ....
Answer:
Correct choice is B
Step-by-step explanation:
Let x% be your final test score, then the average of all test scores is
Since you must have an average between 80% and 89%, then
X is measured in percent, then the greatest value of x can be 100%. You get that

The flux across a surface is an indicator of the rate at which fluid is flowing through it when there is a fluid flowing in three dimensions and a surface positioned inside that space.
<h3>What is Electric Flux?</h3>
- A feature of an electric field is electric flux. One way to conceptualize it is as the quantity of forces interacting in a specific space.
- According to conventional wisdom, electric field lines begin with positive electric charges and conclude with negative charges.
- A closed surface's field lines are seen as negative when they are directed into it, and as positive when they are directed out of it.
- Every field line that is directed into a closed surface continues through the interior and is often directed outward somewhere else on the surface if there is no net charge present within the surface.
- The net, or total, electric flux is zero because the size of the negative and positive fluxes are just about equal.
- A closed surface that contains a net charge will have a total flux that is proportional to the enclosed charge, positive if it is positive and negative if it is negative.
