Orlov [11]

Answer:

Option: A is the correct answer.

         The number of weeds is decreasing by a multiplicative rate.

Step-by-step explanation:

Clear;y from the scatter plot we could observe that with the increasing value of one variable the other variable is decreasing.

Hence, The number of weeds is decreasing.

Also as we could see that the line of best fit is a curve and not a line Hence, the number of weeds are not decreasing by a additive rate  ( since the rate or a slope of a line is constant) it is decreasing by a multiplicative rate.

<em>Based on the graph of a regression model:</em>

<em>Option: A is correct.</em>

Your new job is 25 miles away from your house. If you drive to work at a rate of 50 miles per hour, how long does it take you to
sergeinik [125]

the time taken to get to your work place is 0.5 hour.

The given parameters;

  • distance between  your new job and your house  = 25 miles
  • speed to work, v = 50 mph

The time taken to get to work is obtained by dividing  the distance between your new job and your house, by speed of your motion to work.

Distance = speed x time

Time = \frac{Distance }{speed} \\\\T ime = \frac{25}{50} \\\\Time = 0.5 \ hour

Thus, the time taken to get to your work place is 0.5 hour.

PLS HELP ME PLS I WILL MARK BRAINLIEST PLS
Vesnalui [34]

Answer:

AB = 25

Step-by-step explanation:

First things first, we know that these triangles are similar. Now let's find BC using the Pythagorean Theorem. BC = 5\sqrt5, this side is similar to the 5 side of the smaller triangle. That means each side of the larger triangle \sqrt5 times larger than the corresponding side on the small triangle. That means AB is \sqrt5 times larger than BC as well. So multiply BC by \sqrt5 get us the answer.
