Answer:
15 two-point questions and 5 four-point questions.
Step-by-step explanation:
Let x represent number of two-points questions and y represent number of four-points questions.
We have been given that Janice wants to create a test containing 20 questions. We can represent this information in an equation as:

Since all questions are worth 50 points. We can represent this information in an equation as:

From equation (1), we will get:

Upon substituting this value in equation (2), we will get:







Therefore, there are 5 questions that are worth 4 points each.
Now, we will substitute
in equation (1) to solve for x.



Therefore, there are 15 questions that are worth 2 points each.
Find the length of the line from A to C, which would be the radius using the distance formula:
Distance = √(-5 +1)^2 + 1+2)^2)
Distance = √(4^2 + 3^2)
Distance = √25
Distance = 5
The equation of a circle is written as (x-h)^2 + (y-k)^2 = r^2, where h and k is the center point X and y values and r is the radius.
The center of the circle is located at A ( -1,-2) and the radius is 5.
Replace h, k and r with those values:
(x - (-1))^2 + (y- (-2))^2 = 5^2
Simplify to get:
(x+1)^2 + (y+2)^2 = 25
Answer:
2468
Step-by-step explanation:
A2 = 1234*2 = 2468
Hope its correct :)
Answer:100%. Probability
Step-by-step explanation:
Emily = aa
Man = AA
After crossing the two, the result wI'll be Aa, Aa, Aa, Aa
Since every result has a carrier(a) in it, makes it 100% probability.
