A teacher randomly selects students to write the date on the board each day. If there are 12 boys and 9 girls in the teacher’s class, what is the probability the teacher chooses a girl to write the date on the board?
1 over 12
1 ninth
3 sevenths
3 forth
Answer:
c wich is sevenths
Step-by-step explanation:
The probability the teacher that chooses a girl to write the date on the board is :
C) 3 sevenths.
"Probability"
Given:
Boys =12
Girls =9
Total number of students = 12 + 9 = 25.
So the probability of choosing a girl is = n(girl) / n(all students) = [tex]\frac{9}{25}[/tex]
This is close to 3 sevenths.

Find measure of angle PQS
Answer:
ANGLE PQS = 45°Step-by-step explanation:
angle SRT = 180 - 70 = 110
thus angle QSR = 180 - 20 - 110 = 50
BY Angle sum property
angle PQS = 180 - 85 - 50 = 180 - 135 = 45
Answer:
<PTR+<RTS=180 LINEAR PAIR
<PTR=180-20=160°
Step-by-step explanation:
IN QUADRILATERAL PQRT
<P+<Q+<R+<T=360 SUM OF INTERIOR ANGLE OF QUADRILATERAL IS 360
85+<Q+70+160=360
<Q=360-315=45°
angle PQS=45°
When a standard die is rolled, find the probability of getting a. 5 b. A number larger than 2 c. An odd number.
Answer:
P(getting a 5)=[tex]\frac{1}{6}[/tex]
P(number larger than 2)=[tex]\frac{2}{3}[/tex]
P(numbers which are odd) =[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
When a standard die is rolled, we get sample space as {1,2,3,4,5,6}
So, let's use formula
P(E)=[tex]\frac{outcomes favorable to event E}{Total number of outcomes}[/tex]
For part A:
Event is getting a 5.
So, out of 6 samples , we get one 5 as outcome
So,
P(getting a 5)=[tex]\frac{1}{6}[/tex]
For part B:
The numbers larger than 2 are {3,4,5,6}
So, p(number larger than 2)=[tex]\frac{4}{6} =\frac{2}{3}[/tex]
P(number larger than 2)=[tex]\frac{2}{3}[/tex]
For part C:
The numbers which are odd are {1,3,5}
So, p(numbers which are odd)=[tex]\frac{3}{6 } =\frac{1}{2}[/tex]
P(numbers which are odd) =[tex]\frac{1}{2}[/tex]

The sides of a 30°-60°-90° triangle are in the ratio 1:√3:2
The length of the side opposite the 90° angle is 10,
so the length of the side opposite the 30° angle is 5
and the length of the side opposite the 60° angle is 5√3

CAN SOMEONE PLZ HELP ME WITH THIS 1 QUESTION!?!
no because you wouldn't switch the fraction upside down to make it opposite.
Answer:
What Doug probably means to say is that the reciprocal of -2/5 is 5/-2. So, by this definition, Doug would be correct. However, you would not usually call it the "opposite" of a number, rather, the reciprocal.
The numbers are reciprocals of the other as their product is equal to one "-2/5 * 5/-2 = 1"

The equation of a circle is (x-h)^2+(y-k)^2=r^2 where r is the radius of the circle and (h,k) is the coordinates of the center of the circle. We can see that the radius is 3 units and we are given the location of the center as (-3,1) so
(x+3)^2+(y-1)^2=9
Hayley took a total of 9 quizzes over the course of 3 weeks.After attending 7 weeks of school quater,how many quizzes will hayley have taken in total
Answer:
21 quizzes
Step-by-step explanation:
3 quizzes per week 9÷3=3
7 weeks = 3×7 so 21 quizzes
Answer:
21 quizzes
Step-by-step explanation:
What we know:
- Hayley takes 9 quizzes in 3 weeks
What we want to find:
- The number of quizzes Hayley would've taken after 7 weeks
We need to first find the number of quizzes Hayley would take in 1 week and then multiply that number by 7. To find the number of quizzes per week, divide 9 by 3:
9÷3=3
Therefore, every week, Hayley takes 3 quizzes.
Now, we multiply 3 by 7:
3×7=21
Therefore, after attending 7 weeks of school, Hayley would've taken 21 quizzes in total.
I hope this helps!
