A tub of water is emptied at a rate of 3 gallons per minute. The equation y –12 = –3(x – 1) models the amount of water remaining

, where x is time (in minutes) and y is the amount of water left (in gallons). Analyze the work shown below to determine the initial amount of water. 1. Solve for the y-variable.     y – 12 = –3(x – 1) y – 12 = –3x + 3 y = –3x +15   2. Write the equation using function notation.  f(x) = –3x +15 The tub started with ____ gallons of water.

A bag contains 33 red marbles, 6 white marbles, and 5 gray marbles. You randomly pick out a marble, record its color, and put it
Ksju [112]
<h3>Total 73 times we can expect white or gray marbles.</h3>

Step-by-step explanation:

Total number of marbles = 33

Number of white marbles  = 6

Number of gray marbles  = 5

Now, as we need to pick white or gray marbles, so favorable outcomes

=  6+ 5  = 11 marbles

Now, P(Picking out 1 white or gray marble)  = \frac{\textrm{Total Favorable outcomes}}{\textrm{Total Outcomes}}   = \frac{11}{33}   = (\frac{1}{3})

Here, the same experiment is repeated 220 times.

So, the Combined Prediction

= Probability at first attempt  x Number of repetitions

= (\frac{1}{3} ) \times 220 = \frac{220}{3}  = 73.33 \approx 73

⇒The combined prediction after 220 attempts  = 73

Hence,  total 73 times we can expect white or gray marbles.

Marlon earned $8.50 per hour plus an additional $80 in tips waiting tables on Saturday. He earned at least $131 in all. If h rep
ella [17]

Answer:

<h2>8.50h + 80 ≥131</h2>

Step-by-step explanation:

The answer is not in the option

Step one:

given data:

we are told that the hourly earning= $8.50

then additional tip=$80

total earnings=$131.

Step two:

the linear function for the total earning is the same as the equation of a line

y=mx+c

where

y represents the total earning of $131

m represents the hourly earning= $8.50

x represents the number of hours h

c represents the tip of $80

The expression for the situation is modeled as

<h2>8.50h + 80 ≥131</h2>
