Colby graphed a scatter plot of student exam scores (y) and the number of hours each student had slept the night before the exam. She drew the trend line and calculated its equation to be y=9/2x + 60. What is the predicted score for a student who slept 6 hours the night before the exam?

Answer:

12x = $120

Step-by-step explanation:

12 tickets * price = $120

Answer:  [tex]-7 \le x \le 2[/tex]

On a keyboard you can type -7 <= x <= 2

The symbol "<=" without quotes means "less than or equal to".

===========================================================

Explanation:

The domain is the set of all allowed x inputs of a function or relation.

Start at the left-most point on the diagonal line. Draw a vertical line straight down to the x axis. You should arrive at x = -7. Do the same for the right-most point on the diagonal line. You should arrive at x = 2. Refer to the diagram below.

Shade everything between x = -7 and x = 2. This visually shows the set of all values between -7 and 2, including both endpoints. We include both endpoints due to the filled in circles (as opposed to open holes). The diagram shows the domain as the blue segment on the x axis.

To mathematically describe "numbers between -7 and 2 including both endpoints", we can write [tex]-7 \le x \le 2[/tex].

We can say "x is greater than or equal to -7 AND x is less than or equal to 2", but for me it's easier to say "x is between -7 and 2 including both endpoints".

Flying against the wind, a jet travels 1860 mi in 3 hours.

Flying against the wind, a jet travels 1860 mi in 3 hours. Flying with the wind, the same jet travels 9180 mi in 9 hours. What is the rate of the jet in still air and what is the rate of the wind?

Let J = rate of jet in still air

Let W = rate of wind

Distance formula: d = rt so r = d/t

Flying against the wind the Jet flies at a rate of J - W = 1860mi/3hrs = 620 mph

Flying with the wind the Jet flies at a rate of J+W = 9180mi/9hrs = 1020 mph

The average of these two rate is the speed of the Jet in still air

J = (620+1020)/2 = 820 mph

J - W = 620 so

820 - W = 620

W = 820 - 620 = 200 mph

The Jet in still air flies at a rate of 820 mph

The wind speed is 200 mph

Answer:

2 1/3

Step-by-step explanation:

1 3/4  is equivalent to 7/4

1 1/3 is equivalent to 4/3

7/ 4 x 4/3

reduce with greatest common factor so the two 4 are out (show a line crossing out the top and bottom 4 )

now you're left with 7 x 1/3 = 7/3

7/3 = 2 1/3

The product of two given mixed fractions is [tex]2\frac{1}{3}[/tex].

The given mixed fractions are [tex]1\frac{3}{4}[/tex] and [tex]1\frac{1}{3}[/tex].

The product of two fractions is the product of the numerators and the product of the denominators.

Product of two fractions = Product of their denominators / Product of their numerators.

Here, the mixed fraction [tex]1\frac{3}{4}[/tex] can be written as [tex]\frac{7}{4}[/tex] and the mixed fraction [tex]1\frac{1}{3}[/tex] can be written as [tex]\frac{4}{3}[/tex].

Now, 7/4 × 4/3

= 7/3

= [tex]2\frac{1}{3}[/tex]

Therefore, the product of two given mixed fractions is [tex]2\frac{1}{3}[/tex].
