PEMDAS

So you would first multiply 8x4 witch is 32 then you would divide 4*2 witch is 2 then the re-written problem would be 32- 2 + 1 then you would go left to right so 32-2 is 30 and 30 + 1 is 31. so your answer is 31. Hope I helped

Answer:

$\sqrt{1314}$

Step-by-step explanation:

a²+b²=c² so: 33²+15²=x²

1089+225=x²

1314=x²

take the square root of both sides

36.249=x or

$\sqrt{1314 }$

Answer:

a - b2

Step-by-step explanation:

STEP 1 :

Trying to factor as a Difference of Squares:

1.1 Factoring: a-b2

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : a1 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares

Final result :

a - b2

HOPE THIS HELPS!

In a particular region, for families with a combined income of $75,000 or more, 15% of these families have no children, 35% of t

SCORPION-xisa [38]

Answer:

The probability distribution for x:"number of children per family for this income group" is:

$\text{P(x=0)}=0.15\\\\\text{P(x=1)}=0.35\\\\\text{P(x=2)}=0.45\\\\\text{P(x=3)}=0.05\\\\$

Step-by-step explanation:

With the information given we have the relative frequencies of each category.

We know:

$\text{P(x=0)}=0.15\\\\\text{P(x=1)}=0.35\\\\\text{P(x=2)}=0.45\\\\\text{P(x=3)}=0.05\\\\$
