Answer:
2
Step-by-step explanation:
Answer:
The answer is a). 5/24.
Step-by-step explanation:
For the seventh graders there are 4 Boys + 2 Girls which totals 6 students.
- The probability that a girl will be picked from the <em>seventh graders is 2/6</em>
For the eighth graders, there are 3 Boys + 5 Girls which totals 8 students
- The probability that a girl will be picked from the <em>eighth graders is 5/8</em>
To find the<u> probability that both are girls</u>, we multiply the two fractions together:
Answer:
y= -x^2+5
Step-by-step explanation:
It normally expontionally goes up, so across the x axis is down so it is negative, and is is all scales up, so the start is 5 up from the origin on the y axis, so it would be y=-x+5
Hope this helped!
Since triangle ABC is isosceles, then angles 1 and 9 are congruent.
4x + 3 = 9x - 47
-5x = -50
x = 10
m<1 = 4x + 3 = 40 + 3 = 43
m<1 = m<9 = 43
Triangle DBE is equilateral, so it is also equiangular.
m< 4 = m<5 = m<6 =60
Angles 3 and 8 are supplementary to congruent angles that measure 60 deg, so 180 - 60 = 120, so
m<3 = m<8 = 120
For angles 2 and 7, use the sum of the measures of the angles of a triangle is 180 deg.
m<1 + m<2 + m<3 = 180
43 + m<2 + 120 = 180
m<2 + 163 = 180
m<2 = 17
m<2 = m<7 = 17
