Trava [24]3 years ago
6 0

Answer:

y = \frac{1}{-1}x + 0    or     y = \frac{1}{-1}x

Step-by-step explanation:

y = mx + c

m = \frac{y_{2} -y_{1}}{x_{2} - x_{1} } }

(x_{1},y_{1}) = (-1,1)\\(x_{2},y_{2}) = (-2,2)

m = \frac{2 - 1}{(-2) - (-1)}

m = \frac{2 - 1}{-2 +1 }

m = \frac{1}{-1}

c = 0

y = \frac{1}{-1}x + 0    or     y = \frac{1}{-1}x

professor190 [17]

Answer:  

We are 85% confident that the proportion of adults who dreaded valentines day is within the range of 8.8% to 21.2%.

Step-by-step explanation:  

Proportion of adults who dreaded valentines day = 15% = 0.15

The margin of error with 85% confidence = 6.2% = 0.062

The confidence interval is given by

p ± margin of error

0.15 ± 0.062

Lower limit = 0.15 - 0.062

Lower limit = 0.088

Lower limit = 8.8%

Upper limit = 0.15 + 0.062

Upper limit = 0.212

Upper limit = 21.2%

So it means that we are 85% confident that the proportion of adults who dreaded valentines day is within the range of 8.8% to 21.2%.

Devon set out to bicycle from Exeter to the beach, a distance for 10 miles. After going a short while at 15 miles per hour, the
enyata [817]

Answer:

Distance between Exeter and the point where flat tire occurred was 1.875 miles.

Step-by-step explanation:

Let the distance of Exeter and the point where bike developed the flat tire was = x miles

Then time taken to reach that point with speed 15 mi per hour = \frac{\text{Distance traveled}}{\text{Time taken}}

= \frac{x}{15} hours

Devon comes back with a speed of 3 miles per hour then time taken to come back = \frac{x}{3} hours

Total time for the entire episode = 48 minutes or \frac{3}{4} hours

Therefore, \frac{x}{15}+\frac{x}{3}=\frac{3}{4}

\frac{x+5x}{15}=\frac{3}{4}

\frac{6x}{15}=\frac{3}{4}

x = \frac{3}{4}\times \frac{15}{6}

x = \frac{15}{8} miles

x = 1.875 miles

Therefore, distance between Exeter and the point where flat tire occurred was 1.875 miles.
