In a french club, these are the numbers of the students:
=> 10 freshman
=>12 sophomores
=>15 juniors
=> 30 seniors in the club.
Then the adviser needs to select 1 to act as guide for the coming visitor. To know the answer, let's solve the average..
=> 10 + 12 +15 + 30 = 67 students
=> 67 / 4 = 16.75
OR
=> 15/67

(b)m,
(c)a,
(d)n.

Answers

Answer:

see explanation

Step-by-step explanation:

The y- intercept is at (0, 6) ⇒ c = 6

The x- coordinate of the vertex is at the midpoint of the zeros, that is

m = $(-3-1)/(2)$ = $(-4)/(2)$ = - 2

Since the zeros are x = - 3 and x = - 1 then the factors are (x + 3), (x + 1) and

f(x) = a(x + 3)(x + 1) = a(x² + 4x + 3)

Comparing with f(x) = ax² + 8x + 6 ⇒ a = 2

Thus

f(x) = 2x² + 8x + 6

Substitute m = - 2 into the equation for value of n

n = 2(- 2)² + 8(- 2) + 6 = 8 - 16 + 6 = - 2

Hence

c = 6, m = - 2, a = 2, n = - 2

Answer:

c = 6, m = - 2, a = 2, n = - 2

At summer camp the ratio of boy to girls was 7:1. If there were 63 boys, how many girls were there

Answers

For every 7 boys, there is one girl

So: 63/7 = 9

There are 9 girls.

9 girls

Because the ratio is 7:1 ,every 7 boy there is a girl. So you just need to take 63÷7 then you will get the number of girls

$^(16))8-1(11)/(16)= (128)/(16)- (1\cdot16+11)/(16)= (128-27)/(16)=\bold{ (101)/(16)} \n \n 1 (3)/(5)+1 (1)/(4)=^(4))(1\cdot5+3)/(5) +^(5))(1\cdot4+1)/(4)= (32)/(20)+ (25)/(20)=\bold{ (57)/(20)} \n \n 5 (1)/(4)-1 (1)/(8)=^(4))(5\cdot4+1)/(4) -^(2))(1\cdot8+1)/(8)= (84)/(16)- (18)/(16)= (66)/(16)^((2)=\bold{ (33)/(8) }$

$\frac{8}1-1(11)/(16)=(8-1)-(11)/(16)=6(16-11)/(16)=\boxed{6(5)/(16)}$
