12 sessions.
EXPLANATION:
each session is 1 3/4 hours.
We need enough sessions for 21 hours.

the equation is 1 3/4 x f = 21

using the multiplication property of equality, we can do 21 divided by 1 3/4

The answer is 12 sessions.

Hope it helps!

A restaurant interest survey of 230 citizens in a town showed that 80 want a new Chili's, 120 want a new Red Lobster, and 20 wan
mr_godi [17]

The right solution to the given question is "\frac{2}{23}", "\frac{6}{23}" and "\frac{5}{23}".

According to the question,

  • a+b+c+d = 230
  • b = 20
  • a+b = 80

By putting the value of "b", we get

  • a+20=80

                a = 80-20

                a = 60

  • b + c=120

By putting the value of "b", we get

      20+c=120

              c = 120-20

              c = 100

  • d = 230-60-100-20

By putting the values of "a", "b", "c" and "d", we get    

       d = 50

(a)

P(both Chili's and Red lobster),

= \frac{b}{a+b+c+d}

= \frac{2}{23}

(b)

P(only chili's),

= \frac{a}{a+b+c+d}

= \frac{6}{23}

(c)

P(neither),

= \frac{d}{a+b+c+d}

= \frac{5}{23}

Find the zero of the following function.<br>f(x)=x³-7x²+4x+12 <br><br><br><br><br><br><br><br>​
chubhunter [2.5K]

Answer:

Step-by-step explanation:

Hello, we can notice that f(-1)=0 so (x+1) is a factor and we can write.

f(x)=(x+1)(x^2-8x +12)\\\\=(x+1)(x-6)(x-2)

The sum of the zeros is 8=6+2 and the product is 12=6*2

So the zeroes are 2, 6, -1

thanks
