Suppose the large number of auto accidents in a small town results in new legislation that requires all citizens of the town to

install new anti-lock brakes on their cars. These new brakes cut the time it takes a car to stop by 50%, allowing drivers to avoid collisions with other cars and pedestrians more easily.
The new brakes _______________ the probability that a vehicle will collide with another vehicle but also give drivers an incentive to drive more _____________, which could potentially ______________ the number of car accidents.

Answer:

Step-by-step explanation:

The new brakes decrease the probability that a vehicle will collide with another vehicle. Because the anti-lock brakes cut the time it takes a car to stop by 50%, then total collision will be reduced.

But also give drivers an incentive to drive faster, which could potentially increase the number of car accidents.

Because drivers know that the new brakes cut the time it takes to stop and if they drive faster than before, maybe the new brakes won´t be able to reduce accidents and maybe collisions will increase.

Ten experts rated a newly developed chocolate chip cookie on a scale of 1 to 50. Their ratings were:
Sunny_sXe [5.5K]

Answer:

Option B.

Step-by-step explanation:

The given data set is

34, 35, 41, 28, 26, 29, 32, 36, 38, 40

We need to find the mean deviation of the given data.

Number of observations, n = 10

Mean of the data is

Mean=\dfrac{\sum x}{n}

Mean=\dfrac{34+35+41+28+26+29+32+36+38+40}{10}

Mean=\dfrac{339}{10}

Mean=33.9

Formula for mean deviation is

\text{Mean deviation}=\dfrac{\sum |x-mean|}{n}

\sum |x-mean|=|34-33.9|+|35-33.9|+|41-33.9|+|28-33.9|+|26-33.9|+|29-33.9|+ |32-33.9|+|36-33.9|+|38-33.9|+|40-33.9|=41.2

\text{Mean deviation}=\dfrac{41.2}{10}

\text{Mean deviation}=4.12

The mean deviation of the ratings is 4.12.

Therefore, the correct option is B.

Which equation is an identity?
spayn [35]
7z + 10 - z = 8z - 2(z - 5)
7z + 10 - z = 8z - 2z + 10
6z + 10 = 6z + 10
6z - 6z = 10 - 10
0 = 0

Therefore, 7z + 10 - z = 8z - 2(z - 5)
