Answer:  First option is correct.

Step-by-step explanation:

Since we have given that

$12.60 for 7 bottles of juice.

then, cost of each bottle of juice would be

\dfrac{12.60}{7}=\$1.8

$10.98 for 6 bottles of juice.

then, cost of each bottle of juice would be

\dfrac{10.98}{6}=\$1.83

$18.10 for 10 bottles of juice.

then, cost of each bottle of juice would be

\dfrac{18.10}{10}=\$1.81

$16.38 for 9 bottles of juice.

then, cost of each bottle of juice would be

\dfrac{16.38}{9}=\$1.82

Hence, $12.60 for 7 bottles of juice is the best buy as it is the cheapest one.

Therefore, First option is correct.

natulia [17]

Answer:

a. The Venn diagram is explained in the attached word file.

0.61                                    

b. Not independent

Step-by-step explanation:

a. The hypothetical 1000 table for given situation is

                                          Adult(A)        Not Adult (not A)        Total

Travel outside (T)                 610                170                               780

Not Travel outside (not T) 110                110                               220

Total                                 720                280                               1000

P(Adult and travel outside)=P(A and T)=610/1000=0.61

b. Multiplication rule for independent events is

P(A and B)=P(A)*P(B)

P(A and T)=0.61

P(A)*P(T)=0.72*0.78=0.56

As P(A and T) is not equal to P(A)*P(T), so event "being an adult" and "travel outside" are not independent.

Ganezh [65]

Answer:

1.38 to the nearest hundredth.

Step-by-step explanation:

Dividing:

x + 1 ) 3x - 1 ( 3            

          3x + 3

                -4

so (3x - 1) / (x + 1) =  3  - 4 / x+ 1

Integral  of (3  - 4 / x+1 )  = 3x - 4 ln(x + 1)

Between  limits of 1 and 2 we have:

(3(2) - 4 ln 3) - (3 - 4 ln2)

=  1.6056 - 0.2274

= 1.3782.
