Answer:

Part A = D

Part B = 5 and 50

Step-by-step explanation:

Part A:

area = 5*4x = 20x

so, $100 \leq 20x \leq 1000$

Part B:

to leave it only by x, you divide both sides by 20

100/20 = 5, 1000/20 = 50

which $5\leq x\leq 50$

The chart shows the cost of tuition at a certain state university. Model the data in the chart with a linear function, using the

Dimas [21]

Answer:

The cost in 2007 - 2008 = $15,795.5

The linear model for the data is y = $650.5·x + $9290.5

Step-by-step explanation:

The given data can be presented as follows;

College year, x, Estimated tuition, y

1997-1998, 0, $9412

1998-1999, 1, $9941

1999-2000, 2, $10561

2000-2001, 3, $11242

2001-2002, 4, $11965

2002-2003, 5,

2003-2004, 6,

2004-2005, 7,

2005-2006, 8,

2006-2007, 9,

2007-2008, 10,

With points (1, 9941) and (3, 11242), we have the slope given by the equation;

$m = \dfrac{y_2 - y_1}{x_2 - x_1}$

Which gives;

$m = \dfrac{11242 - 9941}{3 - 1}= 650.5$

Therefore;

y - 11242 = 650.5 × (x - 3)

y= 650.5·x - 650.5 ×3 + 11242

y = 650.5·x + 9290.5

Therefore from the above table at 2007 - 2008, the value of x should be 10, we therefore have;

y = 650.5×10 + 9290.5 = $15,795.5

The cost (estimated tuition) in 2007 - 2008 = $15,795.5

The linear model for the data is y = 650.5·x + 9290.5.

Please help with probability

Nastasia [14]

Step-by-step explanation:

2. The total number of calculators is 6 + 9 + 2 = 17.

When she hands out the first calculator, the probability that it is blue is 2/17.

When she hands out the second calculator, there is one less calculator total, so the probability that it is yellow is 9/16.

The probability of both is therefore:

P = 2/17 × 9/16

P = 9/136

3. There are 13 clubs in a standard deck of 52 cards.

The probability that the first card is clubs is 13/52 = 1/4.

Since you replace the card, there are still 52 cards in the deck. So the probability that the second card is clubs is 13/52 = 1/4.

The probability that both cards are clubs is:

P = 1/4 × 1/4

P = 1/16

4. The total number of pieces of gum is 6 + 9 + 5 = 20.

When you pick the first piece, the probability that it is grape is 6/20.

When you pick the second piece, there's one less piece of gum, and one less grape flavor, so the probability is 5/19.

The probability that both pieces are grape is:

P = 6/20 × 5/19

P = 3/38

5. The total number of drinks is 6 + 3 + 4 = 13.

Since the coach replaces the first drink, the second selection will be independent of the first. So the probability is still P = 6/13.

6. A die has six sides. They are numbered 1 through 6. Three of the numbers are even. Each roll is independent, so the probability of a previous roll does not affect the probability of future rolls.

The probability that you get 3 even numbers, followed by a one, is:

P = (3/6) (3/6) (3/6) (1/6)

P = 1/48
