For the X intercept you set y = 0 and solve for x

Y = - \frac{8}{3}x + 9
0= - \frac{8}{3}x + 9 subtract 9 from both sides
-9 = -\frac{8}{3} x divide both sides by 3
-3 = -8x  divide both sides by -8
\frac{3}{8} = x

X-intercept = (\frac{3}{8}, 0)

lidiya [134]

Answer:

696 miles at the first day, and 174 miles at the second day.

Step-by-step explanation:

Given:

Richard and Linda enjoy visiting Hilton Head Island, South Carolina.

The distance from their home to Hilton Head is 870 miles.

So, the drive takes them 2 days.

<u>Richard and Linda travel four times as far the first day as they do the second day.</u>

Question asked:

How many miles do they travel each day?

Solution:

Let Richard and Linda traveled at the first day = x\ miles

Then Richard and Linda traveled at the second day will be = 4x\ miles

Total distance from their home to Hilton Head = 870 miles

Traveled at the first day in miles + Traveled at the second day = 870

4x+x=870\\ \\ 5x=870\\ \\ Dividing\ both\ sides\ by\ 5\\ \\ x=174\ miles

By substituting the value:

Richard and Linda traveled at the first day = x\ miles = 174 miles

Richard and Linda traveled at the second day will be =  4x\ miles

=4\times174=696\ miles

Therefore, they traveled 696 miles at the first day and 174 miles at the second day.

Natalija [7]

Answer:

Step-by-step explanation:

given that a certain  test preparation course is designed to help students improve their scores on the LSAT exam. A mock exam is given at the beginning and end of the course to determine the effectiveness of the course. The following measurements are the net change in 6 students' scores on the exam after completing the course:

We find

Mean 13.66666667  = 13.7

Standard Error 1.801234145

Margin of error for 90% = 1.645*std error = 2.963

Confidence interval = Mean ±Margin of error

=(10.704, 16.630)

Sample mean = 13.7
