9.Carolyn is taking a long walk. Two miles into the walk, she starts recording her distance and finds the distance from her starting point can be represented by the equation y = 3.5% * 2. What does the slope of
Carolyn's model mean?
(1) She walks at a rate of 2 miles per hour.
(2) She walks at a rate of 3.5 miles per hour.
(3) She was 2 miles away from her starting point when she started recording her distance.
(4) She was 3.5 miles away from her starting point when she started recording her distance

What is 140 squared pleas me i am dumb

Atechnician compares repair costs for two types of microwave ovens (type i and type ii). he believes that the repair cost for type i ovens is greater than the repair cost for type ii ovens. a sample of 6767 type i ovens has a mean repair cost of $79.79$⁢79.79. the population standard deviation for the repair of type i ovens is known to be $19.18$⁢19.18. a sample of 5555 type ii ovens has a mean repair cost of $75.24$⁢75.24. the population standard deviation for the repair of type ii ovens is known to be $21.40$⁢21.40. conduct a hypothesis test of the technician's claim at the 0.050.05 level of significance. let μ1μ1 be the true mean repair cost for type i ovens and μ2μ2 be the true mean repair cost for type ii ovens. step 2 of 4 : compute the value of the test statistic. round your answer to two decimal places.
