Answer:
1/6 = 0.1667 = 16.67%
Step-by-step explanation:
If there are 24 students in the class and 7 of them take neither courses, we have 17 students that take one or both courses.
To find the students that took both courses, we can use the formula:
N(Spanish or French) = N(Spanish) + N(French) - N(Spanish and French)
17 = 13 + 12 - N(Spanish and French)
N(Spanish and French) = 8
Then, the number of students that are taking only French is:
N(only French) = N(French) - N(Spanish and French)
N(only French) = 12 - 8 = 4
So the probability of chosing a student that took only French is:
P(only French) = N(only French) / N(total)
P(only French) = 4 / 24 = 1/6
Answer:
6
Step-by-step explanation:
The equation for a circle is (x-h)^2 +(y-k)^2 = r^2
where (h,k) is the center of the circle and r is the radius
(x+5)^2+(y-7)^2=
36
Rewriting
(x+5)^2+(y-7)^2=6^2
The center is at (-5,7) and the radius is 6
1 is 16 units and 2 is idk
Answer:
80 copies
Step-by-step explanation:
4 minutes= 240 seconds. So I did 240 seconds divided by 3 seconds (one copy is made in that time) then you get 80. I don't know if that explanation make sense but the math checks out.
If BD=DC that means triangle CDB is isosceles triangle and the measure of angles ∡CDB and ∡BCD is the same
∡CDB=∡BCD=70°The angles ∡ADB and ∡CDB are adjacent and suplementary angles
It means
∡ADB + ∡CDB = 180°
∡ADB = 180° - ∡CDB
∡ADB = 180° - 70°
<u>∡ADB = 110°</u>
