P(A) = 0.3
P(B) = 0.5
P(A and B) = 0.3 × 0.5
P(A and B) = 0.15

P(A) = x
P(B) = 0.9
P(A and B) = x · 0.9
          0.45 = 0.9x
           0.9      0.9
           0.5 = x
P(A) = 0.5

Divide 5600 in the ratio 4 :5:7 <br>​
Elis [28]

Answer:

Step-by-step explanation:

So in our case, let assume 'x' as a common factor.

Thus,

4x + 5x + 7x = 5600;

16x = 5600;

x = 5600/16 = 350.

So,

4x= 350*4 =1400;

5x= 350*5 = 1750; &

7x= 350*7 = 2450.

Your answer is, 5600 = 1400+1750+2450 which is in ratio of 4:5:7.

Irina18 [472]

Answer:

Sarah have \frac{5}{4} bottle of water.

Step-by-step explanation:

We are given that,

Total number of bottles = 5

As, each bottle is divided into 4 portions.

The amount of water per person = \frac{1}{4}

Further, Sarah took 1 portion from each bottle and there are 5 bottles.

So, the amount of water Sarah have = \frac{1}{4}\times 5 = \frac{5}{4}

Hence, Sarah have \frac{5}{4} bottle of water.

Find (r-s) (t-s) + (s-r) (s-t) for all numbers r, s, and t. (a) 0 (b) 2 (c) 2rt (d) 2(s-r) (t-s) (e) 2(r-s) (t-s)
lyudmila [28]
Notice that the 2 expressions have 2 common terms.

(r-s) is just (s-r) times (-1)

similarly

(t-s) is just (s-t) times (-1)

this means that :

(r-s) (t-s) + (s-r) (s-t)=-(s-r)[-(s-t)]+(s-r) (s-t)

the 2 minuses in the first multiplication cancel each other so we have:

-(s-r)[-(s-t)]+(s-r) (s-t)=(s-r) (s-t)+(s-r) (s-t)=2(s-r) (s-t)
