Answer:

First you convert the mixed numbers into improper fraction

8\frac{3}{8} = \frac{67}{8} \\\\6 \frac{3}{4} = \frac{27}{4}

Solution

A=\frac{\frac{27}{4}  + \frac{67}{8} }{2}

A=\frac{\frac{54 + 67}{8} }{2}

A\frac{\frac{121}{8} }{2}

A=\frac{121}{8} * \frac{1}{2}

A= \frac{121}{16}

A= 7 \frac{9}{16}

What is the simplified form of the following expression? 5√8-√18-2√2
Romashka [77]

Answer:

Option (B) is correct.

To prove

As given the epression in the question is given by

= 5\sqrt{8} - \sqrt{18} - 2 \sqrt{2}

Now simplify the above

Terms are written as

\sqrt{8} = \sqrt{2\times 2\times 2} = 2 \sqrt{2}

\sqrt{18} = \sqrt{3\times 3\times 2} = 3 \sqrt{2}

Put in the above expression.

= 5\times 2 \sqrt{2} -3 \sqrt{2} - 2 \sqrt{2}

= 10 \sqrt{2} -5 \sqrt{2}

=5 \sqrt{2}

Therefore\ the\ expression\ 5\sqrt{8} - \sqrt{18} - 2 \sqrt{2}\ is\ equivalent\ to\ 5 \sqrt{2} .

Given ∆QRS≅∆TUV, QS=5v+3, and TV=6v−9, find the length of QS and TV.?
Kisachek [45]
If <span>∆QRS≅∆TUV, Their corresponding sides would be equal so, 
QS = TV
5v + 3 = 6v - 9
6v - 5v = 3 + 9
v = 12

Now, QS = TV = 5(12) + 3 = 60 + 3 = 63

In short, Your Answer would be Option B

Hope this helps!</span>

The probability that a newborn baby at a certain hospital is male is 50%. Find the probability that 7 or 8 out of 10 babies born
marin [14]

Answer:

0.1611

Step-by-step explanation:

Uaing the binomial probability relation :

p = 0.5 ; q = 1 - p = 0.5

n = 10

Using the relation :

P(x = x) = nCx * p^x * q^(n-x)

P(x = 7) = 10C7 * 0.5^7 * 0.5^3

P(x = 7) = 0.1172

x = 8 ;

P(x = 8) = 10C7 * 0.5^7 * 0.5^3

P(x =8) = 0.0439

P(x = 7 or x = 8) = 0.1172 + 0.0439 = 0.1611
