you are allowed to work a total of no more than 30 hours each week at your two jobs. Lawn mowing pays $5 per hour and babysittin

timama [110]

Answer:

5X + 8Y >= 300; intersection at (-20, 50)

Step-by-step explanation:

let t = work hours

0 < t < 30

X = time lawn mowing

Y = time babysitting.

X + Y < 30

5X + 8Y >= 300

We could solve...

X < 30 - Y

5(30 - Y) + 8Y >=300

150 - 5Y + 8Y >= 300

3Y >=150

Y >=50

then X < -20

intersection at (-20, 50)

RUDIKE [14]

A) 0.1211
B) 0.3889
C) 0.9782

Explanation:
A) We use a binomial distribution for this:
$_nC_r(p)^r(1-p)^{n-r}
\\
\\_{12}C_3(0.42)^3(1-0.42)^{12-3}=_{12}C_3(0.42)^3(0.58)^9=0.1211$

B) Using a graphing calculator, we find the sum of the binomial probabilities from 0 up to (not including) 5: 0.6111. Now subtract this from 1, since we want everything greater than or equal to 4: 1 - 0.6111 = 0.3889

C) Using a graphing calculator, we find the sum of the binomial probabilities from 0 up to (not including) 8: 0.9782
