A lawyer drives from her home, located 15 miles east and 28 miles north of the town courthouse, to her office, located 6 miles w
natali 33 [55]

Answer:

Step-by-step explanation:

I know the answer is 26 miles but I cannot figure out how they came up with that answer using the distance formula.It looks like you need to find the shortest distance (as the crow flies) between the home and the office.

Use the Pythagorean Theorem.

6^2 + 10^2 = c^2

136 = c^2

11.67 = c

4^2 + 14^2 = c^2

212 = c^2

14.56 = c

11.67 + 14.56 = 26.2 = 26 miles

The manager of a grocery store reports that there is a 12 percent chance that a customer buys apples during a shopping trip, a 5
Ivanshal [37]

Answer:

The probability of a customer buying carrots is 0.10.

Step-by-step explanation:

Here, given:

P (Customer buying apples) = 12%  

⇒   P(A) = 12 \100 = 0.12

P(Customer Buying apples AND Carrots) = 5%  

   ⇒   P(A ∩ C ) = 5 /100 = 0.05

P(Customer buying apples OR carrots ) = 17%    

⇒   P(A∪ C) = 17/100 =   0.17

Now, we know that:

<h3> P(X ∪ Y) = P(X) + P(Y) -  P(X ∩ Y ) </h3><h3></h3>

Now, here substituting the values, we get:

P(A∪ C)  = P(A) + P(C) - P(A ∩ C )

⇒  0. 17  =  0.12 + P(C) -  0.05

or, 0.17 - 0.07 = P(C)

or, P(C) = 0.10

or, P(Customer Buying Carrots) = 0.10

Hence, the probability of a customer buying carrots is 0.10.

A grocery store sells twelve bottles of water for $13.80 a convenient store sells ten bottle of water for $11.80. which store ha
Mrac [35]

At the same rate, the price of 12 bottles of water at the convenience store would be

(12/10)·$11.80 = $14.16 . . . . . this is more than $13.80

On average the cost for the same number of bottles of water is higher at the convenience store. The grocery store has the better buy.
