Zepler [3.9K]

Answer:

  • D.  l = 3  ||  4 < c < y   ||  8l + 7.5c ≥ 70

Step-by-step explanation:

<h3>Work at library</h3>
  • Time  = 3 hours ⇒ l = 3
  • Payment = $8 per hour
  • Total payment = 8l
<h3>Work at coffee shop</h3>
  • Time = between 4 and 7 hours ⇒ 4 < c < 7
  • Payment = $7.5 per hour
  • Total payment = 7.5c

Target income = at least $70 daily  

<u>So the system as per above parameters:</u>

  • l = 3
  • 4 < c < y
  • 8l + 7.5c ≥ 70

Correct option is D

Ainat [17]

Answer:

\Huge\boxed{z

Step-by-step explanation:

Hello There!

Once again we need to isolate the variable using inverse operations

to get rid of the -8.2 we add 8.2 to each side

-8.2+8.2 cancels out

-9.7+8.2=-1.5

now we have

-1.2z>-1.5

now we wan to get rid of the -1.2

to do so we want to divide each side by -1.2

\frac{-1.2z}{-1.2} =z\\\\\frac{-1.5}{-1.2} =1.25

Remember we have to flip the inequality sign because we're dividing by a negative number

we're left with

z<1.25

The sale bin in a clothing store contains an assortment of t-shirts in different sizes. There are 7 small, 8 medium, and 4 large
umka21 [38]

Answer:

P(at least 1 large) = 0.648

P(at least 1 large) = 64.8%

Step-by-step explanation:

We have 7 small shirts, 8 medium shirts and 4 large shirts

Total number of shirts = 7 + 8 + 4 = 19 shirts

The probability that at least one of the first four shirts he checks is a large is given by

P(at least 1 large) = 1 - P(no large)

So first we need to find the probability that the none of the first four shirts he checks are large.

For the first check, there are 15 small and medium shirts and total 19 shirts so,

15/19

For the second check, there are 14 small and medium shirts and total 18 shirts left so,

14/18

For the third check, there are 13 small and medium shirts and total 17 shirts left so,

13/17

For the forth check, there are 12 small and medium shirts and total 16 shirts left so,

12/16

the probability of not finding the large shirt is,

P(no large) = 15/19*14/18*13/17*12/16

P(no large) = 0.352

Therefore, the probability of finding at least one large shirt is,

P(at least 1 large) = 1 - P(no large)

P(at least 1 large) = 1 - 0.352

P(at least 1 large) = 0.648

P(at least 1 large) = 64.8%
