Hello : 
note 1 : 
 p(A|B) = p(A∩B)/<span> p(B)....(1)

note 2 : 
</span> A and B independent: p(A∩B) = p(A)×p(B)......(2)
subsct in (1) :  p(A|B) = p(A∩B)/ p(B)
                                   =  (p(A)×p(B))/p(B)
    p(A|B) = p(A) = 0.70

Points (3,2) and (-5,6) are endpoints of the diameter of a circle.
vichka [17]

Answer:

A.8 B.(-1,4) C.(1,4)

Step-by-step explanation:

First, know that (3,2)=(x1,y1) and (-5,6)=(x2,y2)

A. The diameter is 8, given the diference between x1 and x2: 3-(-5)=8

B. The center point is given by (x1+x2)/2 and (y1+y2)/2

(x1+x2)/2 and (y1+y2)/2 = (3-5)/2 and (2+6)/2 = (-1,4)

C. The symmetric point of C about the x-axis is (1,4)

Amanda spent a total of 70 minutes competing her chores this week. Write and solve an equation to represent the number of minute
gtnhenbr [62]

Answer:

28 minutes spent in washing the dishes.

Step-by-step explanation:

Given the table

Chore             time in minutes

Sweeping           42

Dishes                  ?

Amanda spent a total of 70 minutes competing her chores this week

Total of 70 minutes spent

42 minutes spent in sweeping . to find the number of minutes Amanda spent in washing the dishes , subtract 42 minutes from the total time spent

let x be the number of minutes spent washing the dishes

42+x=70

To solve for x , subtract 42 from both sides

42+x=70\\x= 70-42\\x=28

28 minutes spent in washing the dishes.

Find a general term an for the sequence whose first four terms are given.<br> 2, 4, 8, 16, ...
lapo4ka [179]

Answer:

  an = 2·2^(n-1)

Step-by-step explanation:

There are simple tests to determine whether a sequence is arithmetic or geometric. The test for an arithmetic sequence is to check to see if the differences between terms are the same. Here the differences are 2, 4, 8, so are not the same.

The test for a geometric sequence is to check to see if the ratios of terms are the same. Here, the ratios are ...

  4/2 = 2

  8/4 = 2

  16/8 = 2

These ratios are all the same (they are "common"), so the sequence is geometric.

The general term of a geometric sequence with first term a1 and common ratio r is ...

  an = a1·r^(n-1)

Filling in the values for this sequence, we find the general term to be ...

  an = 2·2^(n-1)
